A field experiment was conducted during Rabi season (November- April) 2015-2016 to study the “Effect of bio-fertilizer and different levels of inorganic fertilizers for soil amelioration growth and yield of field pea (Pisum sativum L.)â€at the Research Farm of Department of Soil Science, Sam Higginbottom Institute of Agriculture, Technology & Science, Allahabad, The experiment was laid out in randomized block design with three levels of NPK ( 0%, 50%, 100%, RDF ) kg ha-1 and three levels of Bio-fertilizer (PSB, Rhizobium and PSB + Rhizobium 75% t ha-1 The treatments combinations were replicated three times and were allocated at random in each replication .The treatment combination T6 [Rhizobium + 100% RDF [N (25 kg ha-1),P(60 kg ha-1),K(20 kg ha-1)] gave the best result with the respect to plant height (82.02cm), number of branches plant-1 (16.93), Number of leaves plant-1(81.33), number of nodules plant-1 (13.27), fresh weight of plant (g)(114.93), dry weight of plant (g) 22.73 it gave highest number of pods plant-1 18.27, number of seeds pod-1-6.73, length of pod (cm)-7.00 and test weight 253.07g. Combined use of inorganic fertilizer and bio-fertilizers resulted in significant increase on enrichment of soil fertility status. The treatment T6 resulted in a slight decrease in soil PH 7.00 and significantly increases EC 0.277dSm-1, bulk density 1.34 g cm-3, particle density 2.67 g cm-3, soil pore space 49.69%, % organic carbon 0.81%, available N 330.59 Kg ha-1, P 32.37 Kg ha-1, K 197.85 Kg ha-1 in the soil .From the economical point of view, the same treatment gave the maximum profit of Rs 64,413with C:B ratio of 1: 2.34. |
