Polyunsaturated fatty acid (PUFA) is commonly found in plants oil. These are considered as essential fatty acid, meaning that they cannot be synthesized by the human body but are vital for normal metabolism. PUFA has been shown to lower the risk of heart attack1 and other cardiovascular diseases1. There is limited evidence that may be useful as an add on for the treatment of depression . The DHA obtained through the consumption of PUFA is vital for grey matter structure of human brain, retinal stimulation and neurotransmission2 From our present studies i.e. effect of organic manure and the bio pesticide “Azadirachtin” on the quality of Soyabean seeds, it has been observed that the percentage of PUFA in the organic soyabean seeds sample is comparatively high i.e.11.20%, 11.79%, 11.56 % during the successive years than the percentage of PUFA in the seeds obtained by the conventional method (11.14%, 11.54%, 11.28 %) during the year 2009, 2010 and 2011 successively. This shows that the organic soyabean seeds quality is quite better. Hence farming of soyabean by using bio-fertilizer and neem based bio-pesticides is preferable.

The striking feature of biopesticides is environment friendliness and easy biodegradability, thereby resulting in lower pesticide residues and largely avoiding pollution problems associated with chemical pesticides. Further, use of biopesticides as a component of Integrated Pest Management (IPM) programs can greatly decrease the use of conventional (chemical) pesticides, while achieving almost the same level of crop yield.³
