Response of Biofertilizer and Foliar Spray of Organic Amendments on Economics and Yield Attributes of Cowpea (Vigna unguiculata L.)

Abstract

Field experiment was conducted on cowpea during Kharif 2021 at (CRF) Crop Research   Farm, Department of Agronomy, Naini Agricultural Institute. SHUATS, Prayagraj  (U.P) India. The experiment entitled as “Response of biofertilizer and foliar spray of organic amendments on economics and yield attributes of cowpea (Vigna unguiculata L.)”, to    study treatments consisting of three kinds of biofertilizers viz.Rhizobium, PSB and Rhizobium + PSB and three types of organic amendments viz. Panchagavya, Jeevamrutha and Beejamrutha. Each of the nine treatments was replicated three times and laid out in a Randomized Block  Design with various treatment combinations. T1: Rhizobium 20 g + Panchagavya 3% foliar spray, T2: Rhizobium 20 g + Jeevamrutha 5% foliar spray,T3: Rhizobium 20 g + Beejamrutha 2% foliar spray ,T4: PSB 20 g + Panchagavya 3% foliar spray,T5: PSB 20 g + Jeevamrutha   5% foliar spray,T6: PSB 20 g + Beejamrutha 2% foliar spray, T7: Rhizobium + PSB 20g + Panchagavya 3% foliar spray,T8: Rhizobium + PSB 20g + Jeevamrutha 5% foliar   spray,T9: Rhizobium + PSB 20g + Beejamrutha 2% foliar spray. The results revealed that treatment 9 (Rhizobium + PSB 20g + Panchagavya 3% foliar spray) recorded maximum on no. of pods per plant (15.43), length of pod (19.53), seeds per pod (10.68), test weight (133.40), seed yield (1025.50), harvest index (41.74), and B:C ratio (2.42).It is concluded that seed treatment  with Rhizobium + PSB 20g + Panchagavya 3% foliar spray was found more productive and economical.
