Abstract

Aim: The aim of the study is to ascertain the response of pearl millet under intercropping system with pulses and their ability to produce higher yield under intercropping conditions. Study Design:  The study was carried out in Randomized block design (RBD). Place and Duration of Study: The field experiment was conducted during rabi season of 2023-2024 at Karunya Institute of technology and Sciences, Coimbatore, Tamil Nadu. Methodology: The experiment was laid out in randomized block design and replicated thrice. It consisted of eleven treatments comprising of pearl millet as main crop and pulses viz., blackgram, greengram, redgram, cowpea and bengalgram as intercrops. Pulses were intercropped with pearl millet in replacement series of 4:1 and 6:1 row proportion. Results: Significantly higher plant height (186.03cm), dry matter accumulation (7386kg/ha), grain yield (2493 kg/ha) and B:C (2.50) ratio was recorded in pearl millet + blackgram (4:1). Further pearl millet equivalent yield (PMGEY) (2711.1 kg/ha) and Relative Crowding Coefficient (RCC) were higher in pearl millet with blackgram 4:1 ratio and Land Equivalent Ratio (LER) were higher in pearl millet + redgram at a ratio of 4:1. Conclusion: These results confirmed that, pearl millet + blackgram 4:1 intercropping system may be suggested to get greater net return and B: C ratio.
