Influence of foliar application of nutrients and plant growth regulators on yield and yield components in Pigeonpea (Cajanus cajan L.)

Abstract

Pigeon pea is most important pulse crop in Kalaburagi district of Karnataka. Yield of pigeon pea is decreasing due to flower drop and pod setting in climatic vulnerability situation. Field experiment was conducted to study source and sink relationship in pigeon pea (Cajanus cajan L.) as influenced by nutrients and plant growth regulators. The results in this investigation noticed that among all the treatments pulse magic spray on pigeon pea variety TS3R have significantly increased the yield (1442 kgha-1) compared to the control (1182 kgha-1) which increased the yield by 22% over control by improving the yield components such as number of pods per plant (212.91), pod length (5.63 cm), test weight (12.48 g) and harvest index (27.80). Pulse magic is a combi product, released by university of agricultural sciences, Raichur as it contains major nutrients, micro nutrients and PGR which helped the crop to achieve maximum yield potential.
