Long term application of fertilizers and manure on productivity and quality determinants of soybean grown on black soil


Author(s): Verma Rohit, Nagwanshi Anil and Dwivedi AK

Abstract: A long term field experiment on different doses of fertilizers along with integration of organic manure in soybean- wheat cropping sequence is in progress at the Jawaharlal Nehru Agricultural University, India since 1972. The effect of continuous fertilizer application on soil nutrient status was evaluated after 43 years of cropping cycle on a Vertitisol with ten treatments replicated four times. The results revealed in the maximum chlorophyll synthesis was noticed when 100% NPK with FYM was practiced. Application of fertilizer in balance amount was also found to have a prominent effect on chlorophyll a, chlorophyll b, total chlorophyll content and Carotenoid content in soybean leaves at 30, 45 and 60 days, stage of growth which was found to increase with successive addition of higher dose of fertilizer over 100% N alone and control. The data also indicated that highest grain yield of soybean was obtained in treatment receiving optimal dose of NPK along with organic manure (100% NPK + FYM) on the contrary and the lowest yields of soybean was recorded with imbalance fertilizer addition and control. However, integrated application of fertilizer with organic manure noticed remarkable higher content of protein and oil content in soybean crop grown on a Vertisol.
