Effect of nutrient and weed management on growth and productivity of field pea [Pisum sativum L. var. arvense]

Abstract

In order to study the effect of different nutrient and weed management practices a field experiment, entitled “Effect of Nutrient and Weed management on growth and productivity of field pea (Pisum sativum L. var. arvense)” was conducted at the Agricultural Research Farm (Department of Agronomy), Raja Balwant Singh College, Bichpuri (Agra) during Rabi seasons of 2021-22 and 2022-23 with the objectives, to study the effect of nutrient management on growth and productivity of field pea, to find out the suitable nutrient and weed management for field pea and to study the economic feasibility of the treatments. Experiment was laid out using two factor viz., main plot treatments (4): NM0-Control, NM1-100% RDF (20:40:20 NPK kg ha-1), NM2-75% RDF + 2 t FYM ha-1, NM3-75% RDF + 2 t FYM ha-1 + Rhizobium + PSB and sub plot treatments (5): WM0-Unweeded, WM1-Weed free, WM2-Pendimethalin 30% EC @ 1.0 kg a.i. ha-1 as PE + 1 Hand weeding at 30 DAS, WM3-Imazethapyr 10% SL @ 25 ml a.i. ha-1 as PoE at 15-20 DAS, WM5-Quizalofop ethyl 5% EC @ 75 g a.i. ha-1 as PoE at 10-15 DAS. Highest productivity of field pea have been achieved with the application of 75% RDF + 2 t FYM ha-1 + Rhizobium + PSB with weed control using pendimethalin 30% EC @ 1.0 kg a.i. ha-1 as PE + 1 Hand weeding at 30 DAS and the maximum net returns was fetched when nutrient management was done by application of 75% RDF + 2 t FYM ha-1 + Rhizobium + PSB and weeds were controlled with pendimethalin 30% EC @ 1.0 kg a.i. ha-1 as PE + 1 Hand weeding at 30 DAS. But, Maximum B: C ratio was fetched when nutrient management was done by application of 75% RDF + 2 t FYM ha-1 + Rhizobium + PSB, (2.06, 2.27 and 2.16) and weeds were controlled by Imazethapyr 10% SL @ 25 ml a.i. ha-1 as PoE at 15-20 DAS, (2.16, 2.36 and 2.26),during first year, second year and pooled respectively.
