Abstract

A field experiment was conducted during 2010-11 and 2011-12 to evaluate the effect of inorganic, organic and biofertlizers on growth, yield and economics of garden pea. Application of 100% RDF (NPKS i.e. 40:20:20:20) along with 50% RDN (20 kg nitrogen through vermicompost) to garden pea result in higher growth attributes such as plant height (52.05 and 53.85 cm), number of branches plant-1 (5.94 and 6.25), dry matter production plant-1 (31.92 and 33.45 g), root dry weight (1.83 and 2.13 g plant-1), number of nodules plant-1 (20.51 and 21.80) and nodules dry weight (66.63 and 67.88 mg) in the year of 2010 and 2011, respectively. The yield attributes viz, number of pods plant-1 (15.43 and 16.58), number of seeds pod-1 (5.84 and 6.09), 100-grain weight (20.30 and 20.76 g); and grain yield (11.94 and 12.88 g   plant-1) and straw yield (21.50 and 22.30 g plant-1) were significantly higher recorded with the application of 100% RDF along with 50% RDN during both the years, respectively. The grain (11.53 and 12.62 q ha-1), straw (21.86 and 23.32 q ha-1) and biological yield (30.95 and 35.93 q ha-1) were recorded with above treatment in respective years. Gross return, net return, B:C ratio, production efficiency (kg day-1 ha-1) and economic efficiency (Rs. ha-1 day-1) were also noted higher with 100% RDF +50% RDN during both the years. The seed inoculation with biofertilizers + zinc @ 5 kg ha-1 gave the significantly higher growth and yield attributes; seed yield (10.73 and 11.97 q ha-1), straw yield (19.65 and 21.15 q ha-1) and biological yield (30.56 and 33.13 q ha-1) in both the years, respectively. In both the years, gross return (Rs. 36131 and 40151), net return (Rs. 24495 and 28515), B: C ratio (2.07 and 2.42), production efficiency (9.67 and 10.99 kg day-1 ha-1) and economic efficiency (Rs. 221 and 262 day-1 ha-1) were obtained with the combined applied of biofertilizers + zinc @ 5 kg ha-1 during both the years, respectively
