abstract
Need for horizontal expansion of redgram led to new niches like rice fallows, which offer a huge potential for short duration pulses. Selecting suitable variety with an optimum planting density and fertilizer dose is necessary towards improved growth apart from higher yields. The present investigation was carried out to study the influence of varieties, planting densities and phosphorus levels on growth and yield of rice fallow redgram. The experiment was carried out during rabi, 2022-23 and 2023-24, at RL 12, block 3 and 4, International Crops Research Institute for Semi-Arid Tropics (ICRISAT), Patancheru, Hyderabad. The findings revealed that, among the varieties, ICPV-21333 registered higher plant height, leaf area, dry matter production and seed yield during both the years. While planting density at 30 x 10 cm resulted in higher plant height, dry matter and seed yield, but on the other hand leaf area plant^-1 was highest with 45 cm x 10 cm. Application of 50 kg P₂O₅ ha^-1 recorded higher growth and seed yield and remained at par with application of 37.5 kg P₂O₅ ha^-1, respectively.
