Crop genetic improvement, whether through GM technology or conventional methods, is just one avenue for enhancing crop performance. Various other strategies such as refining farm practices and optimizing the use of irrigation, drainage, herbicides, pesticides, and fertilizers contribute significantly to boosting crop production.
Implementing advanced farm practices, optimizing irrigation and drainage systems, using herbicides and pesticides judiciously, and adopting strategic fertilization methods are essential for maximizing crop productivity. Crop genetic improvement, whether through genetic modification or conventional breeding, remains crucial but must be complemented with a holistic approach to ensure sustainable and efficient crop production.
Crop genetic improvement, by GM or conventional approaches, is only one of many methods that can be used to improve crop performance. Others involve improvements in farm practices, irrigation, drainage, and herbicide, pesticide and fertiliser use.
What is the most thirsty crop?
Some of the most popular, water-intensive crops include: Rice. Sugarcane. Corn.
What is the formula for crop productivity? The formula is H/P x Y where H is acres harvested, P is acres planted and Y is the yield per acre. Example, 20,000 acres was planted in crop X. The yield for the crop was 50 bushels per acre. 18,000 were actually harvested.
Why is GMO bad for crops?
Research indicates that GM crop technology can result in a net increase in herbicide use and can foster the growth of herbicide resistant weeds. In addition, there is concern that the use of GM crops may negatively impact the agriculture ecosystem.
Which method is used for crop improvement?
If you know which gene(s) underlie the trait you want to introduce into your crop, you can use marker-assisted breeding (also called molecular breeding). This method is much faster than traditional breeding, and it can be used for traits like drought tolerance that involve variations in multiple genes.
Which factor is mostly used in crop improvement?
Biotic factors include diseases, pests, weeds, and nematodes, whereas abiotic factors include water logging, drought, salinity, etc. All of these factors have an impact on crop productivity. Crop production can be increased by developing resistant varieties to these factors.
What are the three factors for improving crop quality?
b) Improvement of quality: The crops have increased amounts of nutrients like proteins, minerals like zinc, calcium etc. c) Resistance to biotic and abiotic stress: Insects, pests, dry environments can cause stress to the crops, so it has to be controlled to improve the variety of crops.
What is the quickest method of crop improvement?
The correct answer is mutation breeding: Plant breeding is the technique used to improve the variety of plants for human welfare. Introduction, selection, hybridization and mutation breeding are the main methods of crop improvement along with polyploid breeding, tissue culture and genetic engineering.
What is one way farmers can improve crop yields?
Fertilisers. Chemical fertilisers can improve plant yields by providing crops with optimum levels of mineral ions and replacing any mineral ions that are missing. Selective breeding. Crops and livestock can be improved through selective breeding.
Which factor does not increase productivity of crop?
Answer: change in maturity duration. Explanation: because change in maturity duration will only give us the product faster but not more in quantity, the quantity of the crop will remain the same.
How many years of crops do we have left?
Today, scientists are trying to conclude on how many harvests we have left and the numbers are worrying. The figure circling around global media and discussed by scientists is that we may only have 60 harvests left to feed the world. However, a precise figure cannot be exactly finalised.
Does corn height affect yield?
Are there yield consequences of unusually shorter corn? There are probably no negative consequences, unless the short height is dramatic enough to significantly reduce crop canopy cover and harvest of sunlight.
What is the formula for crop yield?
Count the number of grains in at least 20 heads or pods and average (B) Using Table 1 determine the grain weight for the crop concerned (C) Yield in t/ha = (A × B × C) / 10,000.
Which of these is required for a good yield?
There are certain conditions which are very important for producing the good crop yield. Fertile and right kind of soil, seeds, water and protection of crops from weeds and pests as well as the use of proper implements and practices-all determine the quality and quantity of crop.
What decreases crop yield? For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.
What is the major determinant of crop yield?
The major factors affecting crop growth and development are radiation, temperature (yield determining), water, nutrition (yield limit- ing), and pests and diseases (yield reducing) (Van Ittersum and Rabbinge, 1997).
In conclusion, improving crop production requires a multifaceted approach that encompasses sustainable farming practices, adoption of innovative technologies, and investment in research and development. By promoting soil health, water conservation, and biodiversity, we can enhance crop yields while minimizing environmental impact. Additionally, empowering farmers with knowledge and resources, creating resilient supply chains, and prioritizing food security will be crucial steps in ensuring a sustainable future for agriculture. Collaborative efforts among stakeholders, policymakers, and communities will play a key role in driving positive change and fostering a more productive and resilient food system for generations to come.
