Wheat is grown for food, Groundnut is a legume crop and an oil seed also, most portion of it is grown for the production of groundnut oil. Jute is a well-known fiber plant, grown in India on a commercial level and sugar beet is used to produce beet sugar because of its 16% of sugar content.

Nitrogen losses in any field occur mainly because of ammonia volatilization, denitrification, leaching, agricultural runoff, etc. And as in rice cultivation plantation is submerged type, ammonia based fertilizers are not recommended in flooded rice systems due to potential N loss through denitrification in the anaerobic plough layer. Denitrification losses of nitrogen in rice can be prevented by placing ammonical fertilizers into the reduced zone.

Soybean is a legume crop, that forms symbiotic association with rhizobium bacteria in the root area to form nodules for fixing atmospheric nitrogen. Soybean is mostly inoculated with Rhizobium japonicum.

Magnesium is the central core of the chlorophyll molecule in plant tissue. Chlorophyll is the pigment that is required for the process of photosynthesis, thus magnesium plays a vital role in the process of food synthesis in plants.

Rice is a short day plant, photo periodically those plants which require around 8 hrs of day light for flowering, fruiting, and its proper growth is short day plant while those which require around 12 hrs of daylight for heading and flowering to occur.

The cohesiveness and tenderness of cooked rice depend largely on starch while starch is a mixture of two polymers amylose and amylopectin, so it ultimately depends upon the proportion of amylose and amylopectin present in the rice. Rice with high amylose content becomes firm and dry after cooking, whereas rice with medium amylose content makes the rice softer and stickier and low amylose content makes it quite soft and sticky.

Genetically modified organisms (GMO) is the term used for the organisms produced through the process of Genetic Engineering using techniques like recombinant DNA technology, and reproductive Cloning to experiment with genes and DNA.

Boron is the essential element required for the translocation of sugars in sugarcane. Translocation as the term suggests means the transfer of sugars produced in the leaves to all other parts of the plant via the phloem.

A major proportion of our atmosphere constitutes nitrogen and it is present in different forms of our atmosphere. Nitrogen is very important for the proper growth and development of plants. Plants take nitrogen in the form of nitrates. Moreover, nitrates can be easily lost to groundwater. Some of the nitrogen in the form of ammonia is also absorbed by plants but it is directly used in protein synthesis.

A Cotton bale is a standard sized and weighed pack of compressed cotton lint after grinning. Different countries have their standards of bale size, in India, the standard bale size is 170 kgs. The cotton yield is calculated in terms of the number of bales.
