Influence of INM on nutrient uptake and quality of soybean in black cotton soil of Maharashtra

Abstract

A field experiment was conducted on typic haplustert at Department of soil science and Agricultural Chemistry, College of Agriculture Latur during Kharif season of 2008-2009 on Soybean. Uptake and quality of soybean was significantly influenced by integrated nutrient management. There was a significant increase in uptake of N, P, K and S at all the critical growth stages of soybean with combined application of chemical fertilizers along with enough bulk of farm yard manure. Uptake of nutrients were significantly higher with treatment (T9) 100 % RDF + 10 t FYM ha-1 + 45 kg S ha-1 + Biofertilizer Followed by T8 (50%RDF+10t FYM ha-1 +45kg s ha-1 + Biofertilizer). At all the critical growth stages of soybean maximum value of 100 seed weight (14.67g) of soybean was recorded with treatment T9 and it was at par with treatment T8. Both protein content and protein yield were significantly improved due to treatment T9. Treatment T9 recorded highest protein content (40.68%) in soybean than the rest of the treatment. The treatment T9 recorded maximum oil content (20.0%). which was significantly superior over all other treatments while highest oil yield (546.2 kg ha-1) due to treatment T9 was at par with the treatment T8 and T4.
