Study of productivity and economics of pearl millet (Pennisetum glaucum L.) Variety Jaigro 2828 in relation to phosphorus and plant growth regulators

Abstract

Background: Pearl millet can thrive in a wide range of local conditions. In areas where sorghum cannot thrive, pearl millet is a viable alternative. Sorghum and maize can't compete with pearl millet when it comes to soil moisture utilisation and heat tolerance. Objectives: Effects of phosphorus and plant growth regulators on yield and economics of pearl millet. Methods: With the goal of studying the effect of phosphorus and plant growth regulators on yield and economics of Pearl millet (Pennisetum glaucum L.) Var. Jaigro-2828 under a Randomized block design with 10 treatments (T1-T10 The experimental results revealed that Phosphorus 50 kg/ha + NAA 50 ppm + Triacontanol 250 ppm, produced ear head length (22.57 cm), Number of grains/ear head (1989), grain yield (2.77 t/ha), Stover yield (3.80 t/ha) harvest index (43.00%). T9 Phosphorus 50 kg/ha + NAA 50 ppm + Triacontanol 250 ppm produced greater gross returns (1,44,040 INR/ha), net returns (97,650.00 INR/ha), and benefit-to-cost ratios (2.10).
