Effect of PGR's on growth biochemical changes & yield of mustard

Rapeseed-mustard is the third important oilseed crop in the world after soybean (Glycine max) and palm oil (Elaeis guineensis Jacq.). Brassica (rapeseed-mustard) is the second most important edible oil seed crop in India after groundnut and accounts for nearly 30 per cent of the total oilseeds production when compared to other edible oils the rapeseed-mustard oil has the lowest amount of harmful saturated fatty acid. It also contains adequate amount of the two essential fatty acids (i.e linoleic and linolenic) which are not present in many of the other edible oils. The low production of oilseeds has converse the scientists to increase the production of oilseeds. To innovate and implement methods for boosting the yield through proper nutrition plant protection measure improved varieties good physiological practices maintaining internal harmonal balance & source sink relationship.PGRs are extremely important agent and play an important role from germination upto senescence of the plant. PGR''s can play an important role in increasing its yield by making the plants photosynthetically more effective by increasing the rate of photosynthesis and chlorophyll content.
