Yield and economic impact of spacings and varieties of rajma (Phaseolus vulgaris L.) cultivation during kharif season

Abstract

A field experiment was carried out during kharif season of 2023-2024 at Experimental farm, Agronomy section, Oilseed Research Station, Latur. To study Effect of spacings on economics and seed yield of rajma (Phaseolus vulgaris L.) varieties in kharif season. The soil of experimental plot was black clayey in texture, slightly alkaline in reaction having pH (7.7) with chemical composition such as available nitrogen (231 kg ha-1), very low in available phosphorous (18.2 kg ha-1) and very high in available potassium (498.58 kg ha-1). It was well drained and favourable for optimum crop growth. The experiment was laid out in factorial Randomized Block Design with two factors are Spacing and Varieties have nine treatments. The treatments were S1: 45 cm × 10 cm, S2: 45 cm × 20 cm, S3: 45 cm × 30 cm, V1: Phule Rajma, V2: Phule Varun, V3: Arka Komal. The gross size of each experimental unit was 5.4 m × 4.5 m and Net plot size as per treatment. Sowing was done on 9th July 2023 by dibbling method with seed rate as per treatment. The recommended dose of fertilizer for Rajma crop was 120:60:60 NPK kg ha-1. The result of the experiment revealed that among the spacing higher yield attributes such as seed yield (1744 kg ha-1), straw yield (2388 kg ha-1), GMR (Rs.1,39,520 ha-1), NMR (Rs. 92,250 ha-1) and B:C ratio (2.96) was observed with an application of 45 cm × 10 cm (S1) while among varieties higher growth and yield attributes, seed yield (1524 kg ha-1), straw yield (2348 kg ha-1), GMR (Rs.1,21,973 ha-1), NMR (Rs.75,703 ha-1) and B:C ratio (2.63) was observed with a Phule Rajma (V1). In case of seed yield and net monetary returns (Rs. ha-1) application of spacing 45 cm × 10 cm (S1) and variety Phule Rajma (V1) performed better.
