Influence of Pseudomonas and Biofertisol as a Foliar Spray on Soil Properties under STCR Approach

A field experiment was conducted during the rabi season in the Experimental field, Department of Soil Science, JNKVV, Jabalpur (M.P.) under RBD design with four replications comprising five treatments of two types of biofertilizers: Pseudomonas and Biofertisol and scheduled combinations of inorganic fertilizers based on STCR (Soil Test Crop Response) for achieving targeted yield by using variety of vegetable pea, PSM-3. The best response was recorded from the application of treatment T5 (TY120 q(87:147:74) +5tFYM) for increasing the content of soil available nutrients (N, P and K) by 7.89, 29.95 and 8.25%, respectively over that from control. Effect due to T4 was significantly prominent on the proliferation of microorganisms viz., Rhizobium sp., Pseudomonas sp., and Lactobacillus sp. better by 6.79 log cfu (61.38 x 105 cfu g-1 soil), 6.44 log cfu (27.67 x 105 cfu g-1 soil) and 4.42 log cfu (26.18 x 103 cfu g-1 soil), respectively over control. The same treatment T4 induced the enzyme activity of dehydrogenase by 86.99% as compared to that of the control (5.23 µg TPF hr-1 g-1). Yields of the crop were best harvested due to T4 by 81.91% over that of control 56.93 kg ha-1. The vegetable pea (Pisum sativum L.), a cool-season crop and an important pulse crop in India. One of the impediments to supporting vegetable pea production and productivity is low soil fertility. Anthropogenic causes such as heavy use of fertilizer exacerbated the problem. A combination of fertilizers, biofertilizers and FYM are the solution to the problem since it makes use of available organic and inorganic nutrients and microbes to create an environmentally sound and economically sustainable farming system.
