Influence of different organic nutrient sources on nodulation and economics of lentil (Lens culinaris L.) under certified organic production system

Abstract

The field experiment was conducted during Rabi 2019 at SMOF (SHIATS Organic Modal Farm). Department of Agronomy, SHUATS, Prayagraj (UP). The soil of the experimental field is sandy loam in texture, nearly neutral in soil reaction (pH 7.6), the available N, P, K fertilizer is applied through organic fertilizers i.e. Vermicompost and Poultry manure. The treatment consisted of application of Vermicompost and Poultry manure in different levels viz: whose effect is observed on IPL-316. The experiment was laid out in Randomized Block Design with nine treatments which are replicated thrice. The treatment with Vermicompost 2.5 t/ha + Poultry manure 2.5 t/ha shown significantly higher number of nodules (18.85 at 60 DAS) and growth parameters. The maximum gross return (123793.3 ₹/ha), net return (77273.33 ₹/ha) and benefit cost ratio (1.55) is recorded in treatment with Vermicompost 2.5 t/ha + Poultry manure 2.5 t/ha.
