methods to improve crop production

1. Plant introduction usually means the introduction of the plants from places outside the county, may be of same or another continent. Polyploids which originate by multiplication of the chromosomes of a single species are known as autopolyploids or autoploids and such situation is called allopolyploidy Autopolyploids are generally larger in size, have larger cells, stomata, pollen grains and seeds. These approaches have relied on classical econometric methods. Clonal selection generally may be practiced with non-flowering or those species which produce seeds poorly or only under special conditions. Others involve improvements in farm practices, irrigation, drainage, and herbicide, pesticide and fertiliser use. 10 Sustainable farming methods and practices. Any plant material therefore brought from another place may be within or outside the country, may be termed as introduced material or method of plant introduction. The plant part which is used in regeneration is called explants). This method is helpful in conserving hybrid vigour for several generations. (iv) Intrastate or Inter-district plant introduction: Introduction of plant material into different states within the country or from another district within the same state, for e.g., distribution of state recommended varieties of different crops from one district to another within the same state for general cultivation. It can be defined as the “process of introducing plants from their growing locality to a new locality.”. Fertilizers feed the crops by providing them with essential nutrients like phosphorus, potassium & calcium. The ultimate stages of crop production are harvesting and storage. Thus, they can be used in seasons when food i… For maintaining voluntary soil conditions for crops use of fertilizers is a must. The better a crop, the more you make in a good year. A sudden heritable change in a characteristic of an organism is called mutation; function of mutations with the aid of mutagens is called mutagenesis. In 1856, a French man Louis Leveaue de Vilmorin utilized the progeny test to increase the sugar content in the wild sugar beet, hence it is also known as Vilmorin principle. In India, efforts are being made to develop aphid resistant transgenic brassicas by expressing in them protease inhibitor genes from wheat etc.. The following points highlight the six methods of crop improvement. expressing this gene are being cultivated in U.S. A. glutinosa (2n = 24). Answer Now and help others. Most vigorous plants from the mixed population of a crop are selected. It can be practiced in both self-pollinated and cross-pollinated crops. (iii) Inbreeding may be avoided if sufficiently large number and diverse progenies are selected. (D) This method of crop improvement is not applicable to self-pollinated crops (due to less amount of heterozygosity). Johanssen (1903), a Danish botanist, and is commonly used to improve the self- pollinated crops. NIFA programs are working to increase crop production while maintaining the environment by providing services such as: Conducting research on issues that affect horticultural breeding, growth, and production Improving productivity of field and forage crops Ensuring sound use of natural resources, reducing soil erosion, and improving soil quality ii. Storage and Preserving the produced Crops. Likewise, progenies of seeds selected from Pure Line No. This method is also used both in self and cross-pollinated crops for production of pure lines and inbreeds. 5. Acclimatization 3. Enhance the understanding of the basic biology of seed development, maturation, germination, and dormancy to improve seed quality, improve emergence and early season growth of crop species, and allow for more natural management of weed and crop seed banks. The test of genotypic value of an individual based on the basis of performance of its progeny is called progeny test. Mutation Breeding: Crop Improvement Method # 5. What is the role of saliva in the digestion of food? More than 300 varieties have been developed through mutagenesis in various countries. These inputs increase production costs, but they can make a large improvement in plant quality. Share Your Word File Selection of desirable clones from the mixed population of vegetative propagated crops is known as clonal selection. can be isolated from a heterogeneous or mixed population of an old variety. Strip-till is one of the popular farming techniques that warms that soil better and boosts up the crop production. Our mission is to provide an online platform to help students to share notes in Biology. A notable case of recent domestication is that of several members of family Euphorbiaceous producing latex. In India, a number of varieties have been developed by mutation breeding e.g., BGM 408 (Chick pea), Hans (pea), JRO 3690 (Jute), Sharbati Sonora, (Wheat), Jagannath (Rice), Co8152 (sugarcane) etc. 2. In cross pollinated crops it is usually practiced for population improvement purposes, whereas in self pollinated crops it has only a limited use of maintaining purity of a variety. 0 4 ne, ny iii. Our mission is to provide an online platform to help students to share notes in Biology. Synthesized by a cross between Nicotiana tabacum (2n = 48) and TV. These introductions are also termed as exotic collection (EC, Introductions may be from outside the country) or indigenous collections (IC, Introduction may be from other parts or other states of the same country). Crop protection is a critical aspect of production, and it has been shown that … A strain made up of the progeny of a single self-fertilized homozygous individual. Selection with in the original lot of beans was effective because the plants have genetic variation. 2. Domestication of plants is the change of ideotype to adopt them better to manmade environments. Annual crop has better acclimatization capacity than perennial crop because in annuals each generation would produce new gene recombination every year. Some crops are compatible with multi-cropping .In such cases; combination can improve the quality in many ways. Generally a period of 10 to 11 years is required to produce a variety by pure line selection in cross pollinated crop. Tissue Culture 6. Synthesized by a cross between wheat (Triticum aestivum, n = 7) and rye. Efficient use … by John Orlowski, Ph.D – Research Agronomist, Growers In precision agriculture, we often focus on seed and fertilizer to optimize crop production. The new species is called as N. digluta. 1) produced beans averaging 0.64 g in weight (Fig. Acclimatization 3. Crop Improvement Method # 1. (iii) If the progeny of each plant is tested in isolation, it would require lot of area which is not practically possible. 3. Domestication of wild species is still being done and is likely to continue for a long time in near future. He picks of a few plants of better qualities from mixed populations and tries to propagate them. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? It also helps to eliminate unproductive and undesirable types. Crop management software, data science, precision farming technology, and soil health and nutrient management techniques are all ways technology is driving crop protection in modern agriculture. If you can reliably increase yields and, effectively, improve the health of your soil and fields, you’ll have more good years. The other key element needed for plant growth is nitrogen. 4. The cry gene transfers have been so far the most successful. Welcome to BiologyDiscussion! Better systems and methods capable of measuring specific plant parameters (e.g., nutrient status, water status, disease, competing weeds) on a timely basis are becoming available, and are expected to provide information required to enhance crop modeling use and thus improve within‐season management. Isolation, introduction and expression of foreign DNA in plants and animals is called genetic engineering. It is the simplest and oldest breeding method. Domestication is the taming and training of plants to suit the human needs and putting them under cultivation. Many floriculture crops are vigorous and require management of plant height. This approach, called biotechnology , has been shown to increase crop yields worldwide. This method can isolate only superior genotypes from the mixed population. Poehlman (1959). It is the first step in the development of cultivated plants. It can be defined as the process of isolating a desirable homozygous individual from the mixed population and multiplying the same without contamination to release as a new variety. Insect resistant transgenic varieties of maize, soybean, cotton etc. (E) In cross pollinated crops variety produced is heterozygous i.e., mixture of different genotypes. The consumption of fertilizer in … Another pure line (Pure Line No. Content Guidelines 2. Legumes and dried beans have a longer shelf-life and are cheap to buy. (i) This method is very simple and convenient. Plant Introduction: Crop Improvement Method # 2. Hayes, Immer and Smith (1955), A strain in which all members have descended by self-fertilization from a single homozygous individual. The methods are: 1. Discovering Ways To Improve Crop Production and Plant Quality Kim M.Wilkinson 17 Working with plants is a process of discovery. This method of farming has changes in recent years and farmers are using latest equipments for this. The introduction of the genotypes from the place where it is grown to an entirely new area. (ii) Certain methods of progeny selection are complicated. Every crop has specific requirements and a built-in genetic potential for production. (ii) In the identification of superior genotypes, this method is more effective than mass selection because it is based on progeny test and not on the phenotypes of the individual plant. According to the Darwin’s principle “Survival of the fittest” plants which survive through the adversities of nature are preferred and the weaker ones are wiped out. TOS4. (i) All the individuals of a clone are genotypically and phenotypically identical. Why do lymph nodes often swell and become tender or even painful when you are sick? There are 4 methods of artificial selection: It can be defined as selection of a number of phenotypically superior plants heads or seeds from the field population, harvesting and bulking their produce together for sowing the next year’s crop and repeating this process till desired characters are achieved. 3). This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. Acclimatization follows the introduction and both processes go side by side. If the period of acclimatization is very long, the mutation also plays an important role in acclimatization. (C) Pollination need not to be controlled to provide a new variety. It cannot bring any new change in the genotype. The selection pressure ultimately resulted in the appearance of many differences between species and subspecies. Polyploidy 5. The test evaluates the breeding value of a singe plant by the performance of its progeny. (ii) Intercontinental or Inter-countries plant introduction: Introduction of plant material from another country within same continent, for e.g., Litchi and loquat from China. Strip-till is one of the popular farming techniques that warms that soil better and boosts up the crop production. Due to high degree of homozygosity, variations among the varieties are also limited. Books and people can help us learn about plants in the nursery, but the very best teachers are the plants themselves. Similarly, many transgenes have been shown to generate resistance to fungal diseases (e.g.. Vacuolar’chitinase, (β-1, 3-glucanase, groundnut stilbene synthase etc.). Plant growth regulators (PGRs) are also sometimes applied to stimulate branching and/or flowering, to inhibit lower-leaf yellowing, or to increase flower longevity. Some important facts about the acclimatization are: i. The latex of these plants may be commercially used for extraction of petroleum products including petrol and diesel. Make use of fertilisers: As part of the process, soil cultivation is important to maintaining optimal soil conditions for your crops. Share Your PPT File. It is also called as German method or German method of broad breeding because once it was used nicely in Germany for improving the sugar beets and small grains such as rye and wheat. crop production. Natural selection has given the cultivated crops and ‘ecotypes’ in plants. He found that seeds obtained from each plant varied in size and weight but on average the large seeds parents produced progeny with heavier seeds and the smaller seed parents give rise to plants with smaller and lighter seeds. A general procedure for developing a new variety by mass selection is as follows: (A) It is more of an art than a science because it needs no scientific knowledge. Progeny (offspring) can be defined as new individual organisms that results from the process of sexual or asexual reproduction. (D) To meet the need of the farmers, it is the only method for improving the local or wild varieties. They are served as a staple food for the majority of population. In this method, gamma rays and X-rays are the most commonly used physical mutagens, while EMS (ethyl methane sulphonate), EI (ethylene imine) and sodium azide are the most commonly used chemical mutagens. Food crops are crops that contribute to the world’s major food supply. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. v. Varieties are as stable as pure lines and easy to maintain because there is no danger of deterioration due to segregation and recombination. It is very lengthy and laborious process. This is the method BioFlora has used successfully for the past 40 years. It can be defined as to choose certain individual plants for the purpose of having better crop from a mixed population where the individuals differ in characters. Intensification of crop production over the last 50 years has come to be known as the ‘green revolution’ and has been achieved by the use of modern high-yielding varieties while greater benefits have been realized from chemical fertilizers, irrigation, and weed and pest control. These practices can reduce greenhouse gas emissions at the source and, at the same time, maintain or improve yields and enable crop systems to adapt to the projected impacts of climate change. Genetic variability must be present in the introduced material for acclimatization to occur. When a tadpole turns into a frog, its tail shrinks and is reabsorbed. Protecting crops sustainably . Sustainable farming system doesn’t have to be only organic agriculture. Most of the crops were domesticated by the prehistoric man under domestication and the crop species have changed considerably. Domestication is the process of bringing wild species under human management. A group of plants all obtained from a single self-fertilized homozygous plant. Some of our crops are autopolyploids e.g., potato, coffee, sweet potato, ground nut, alfa alfa, banana etc. Best genotype for yield, disease resistance, insect resistance, earliness, quality etc. 4. Answer Now and help others. The growth of tissues of living organism in a suitable culture medium (in vitro)I is called tissue, culture. Mango, citrus, apple, many fruit trees, rose, and many ornamental plants. This method matches crop strains to local soils and climate, applies more precise dates for sowing and makes efficient use of fertilisers. There are more methods that overlap in many principles that are sustainable in the long-run and may be 100 percent organic or at least from the biggest part. Welcome to BiologyDiscussion! This method was developed by Hopkins (1908) and is extensively used in maize. It cannot be used for development of varieties in cross-pollinated crops. Progeny selection is the selection procedure in which superior plants are selected from a heterogeneous population on the basis of performance of their progenies. Crop Improvement Method # 1. Disclaimer Copyright, Share Your Knowledge hirusutum (American cotton) and G. barbadense (Egyptian cotton). (B) Simplest, easiest and quickest method of crop improvement. It is the only method to improve the clonal crops. Disclaimer Copyright, Share Your Knowledge Selection Method for Crop Improvement: It is the simplest and oldest breeding method. (i) In this method no new genetic variability can be created. Impact of Plant Biotechnology in Crop Improvement, Introduction and Selection | Methods | Plant Breeding | Botany, Vegetative Reproduction: Meaning, Methods and Significance | Botany. Thus, nature itself selects the fittest organisms. Continuous breeding leads to homozygosity. Precision Farming Increases Crop Yields Combining sensors and imaging of every plant with real-time data analytics improves farm outputs and reduces waste By Geoffrey Ling , … What is the significance of transpiration? (With Methods)| Industrial Microbiology, How is Cheese Made Step by Step: Principles, Production and Process, Enzyme Production and Purification: Extraction & Separation Methods | Industrial Microbiology, Fermentation of Olives: Process, Control, Problems, Abnormalities and Developments. After reviewing the best evidence, the researcher suggests that … Modern Methods to Improve Crop Production in Plants Crop improvement technologies improve the potentialities of higher yield and food quality in crops. In other words, primary selection refers to selection of plants from a diverse population on the basis of their progeny test. It can be defined as preservation of certain individual plants of desirable characters. Selection within the original mixed lot of beans was effective in isolating lines that were genetically different). wheat varieties from Delhi. In simplest form selection means choosing plants of one’s choice. They comprise grains, seeds, nuts, vegetables, fruits, legumes, spices, herbs, beverages, etc. Mass selection is based on phenotype (external characters) and the harvested seeds are composited without progeny testing. Artifical polypleids have also been synthesized. Therefore, the millennium challenge is to produce more food from less land. Another concern besides harvesting is storage. The process of domestication started when man started superior plants for use. This potential is seldom reached because of limiting factors. Share Your PDF File It operates in the nature without human interference. iii. These are: (iii) Normal flowering and seed setting species: Citrus, mango, pear, peach apple, litchi, loquat and many ornamental plants (to maintain the heterozygous balance vegetative reproduction is essential). Acclimatization is the adaptation or adjustment of an individual plant or a population of plants under the changed climate for a number of generations: Thus, it is a sort of natural selection operating into the introduced plant material. Autopolyploids are produced spontaneously by gamma irradiation, tissue culture and with treatment of the chemicals like colchicine. Another method to improve the productivity of the crop is by using different farming techniques. ii. It is the easiest or most common method of crop improvement. Banana, Pine-apple, aloe, agave, Chrysanthemum. Protecting and Harvesting Crops. Share Your PDF File Here the selecting agent is man. 19 were similar to their parent line in average seed weight. Polyploidy 5. Which part of the male reproductive system store the sperm? Introduction of plant material from another state within the same country, for e.g., N.P. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? Man exploits the variations existing among the species. He first of all suggested the term pure line and defined it as the descendants of a single self-fertilized organism of homogeneous factorial composition. ii. Genetic Engineering. Selection within a pure line is not effective because all the plants in a pure line have exactly the same genotype. 1 were similar to those of the parent line. Developing a drainage system in your crops can help prevent waterlogging and salinization in your soil, both of which can stifle growth and production.
