Influence of Varieties and Spacings on Growth, Yield Attributes and Productivity of Pigeonpea

Abstract

Background: The field experiment was conducted to evaluate pigeon pea varieties viz., AL 882 and Pusa Arhar 16 under different spacing in Amritsar region” during kharif season 2019-2020 at Students’ Research Farm, Department of Agriculture, Khalsa College, Amritsar. Methods: The experiment was laid out in Randomized Block Design (factorial), replicated thrice. There were six treatments of spacing S1 (30 × 12.5), S2 (40 × 12.5), S3 (50 × 12.5), S4 (30 × 25), S5 (40 × 25), S6 (50 × 25cm) and two varieties V1 (Pusa Arhar 16) and V2 (AL 882). All the cultural practices were performed to get maximum productivity of pigeonpea from each plot. Result: The results revealed that cv. AL 882 performed better under spacing 30 × 12.5 cm for growth parameters such as plant height and LAI whereas dry matter accumulation, crop growth rate and number of primary and secondary branches were significantly higher in spacing 50 × 25 cm. Among yield attributes, cv. AL 882 showed significantly higher number of pods per plant, pod length (cm), number of seeds per plant and 100 seed weight (g) under spacing 50 × 25 cm than cv. Pusa Arhar 16. However, seed yield was maximum in wider spacing (50 × 25 cm) and narrow spacing (30 × 12.5 cm) with cv. AL 882 and Pusa Arhar 16, respectively. However, both varieties produced highest stover and biological yield under narrow spacing 30 × 12.5 cm.
