Title : Productivity of soybean (Glycine max L.) and soil properties as affected by integrated nutrient management practices

Abstract :

A field carried out at research farm Department of Soil Science and Agricultural Chemistry, J N. Krishi Vishwa Vidyalaya, Jabalpur during Kharif season of two consequentive years of 2016 and 2017. Experiment was laid out in a Randomized Block Design by replicating thrice. The crop was fertilized with NPK and organic manures as per treatments and applied as basal in all the treatments. Application of all combinations of sources nutrients found to be unable to bring out significant changes in soil properties with respect to pH, EC and OC. However, the status of NP and K markedly increase over control under organically amended treatments and 100% NPK through chemical fertilizers. Furthermore, these three nutrient statuses in post harvest soils showed superiorly over initial value of soil. As regards to the content of chlorophyll a, b and chlorophyll a and b initially it increases with increasing rate up to 60 DAS then the content start decreasing. The treatment having vermicompost @ 1.5 t ha-1 enriched with PSB and Rhizobium and remaining dose of NPK was applied through chemical fertilizers proved as good as 100% NPK through chemical fertilizer alone with respect to chlorophyll content during both the years. The treatment T5 (Vermicompost @ 1.5 t ha-1 enriched with PSB & Rhizobium + RRDFCF) possessed the values of 2.02, 1.13 and 3.15 at 30 DAS 2.07, 1.58 and 3.65 at 45 DAS as well as 2.21 1.64 and 3.85 mg g-1 at 60 DAS a, b and a+b chlorophyll respectively. The highest seed and stover yields (1923 and 3192 kg ha-1), were found under T5. On the other hand, the significantly the lowest yield was secured from the control treatment. The protein per cent in soybean seed was seen to increase up to maximum extent of 41.7% due to application of 100% NPK followed by T3 (FYM @ 2 t ha-1 enriched with PSB & Rhizobium + RRDFCF) i.e. 41.4%.
