Date of sowing and nitrogen levels influenced on phenological effects of irrigated groundnut under climate change

Abstract

The groundnut (Arachis hypogaea L.) crop is subjected to varied climatic conditions and monsoon vagaries on grown under irrigated and rainfed conditions. An experiment was led at Agricultural College and Research Institute, Madurai. Effects on dates of sowing and nitrogen levels influenced on phenology of groundnut (Arachis hypogaea) under climate change. Twelve treatment blends with four dates of sowing (D1: 9 th February, D2: 19 th February, D3:29 th February, and D4:9 th March) and three nitrogen levels on (100% RDN, 75% RDN, 125% RDN) in factorial randomized block deign was recreated thrice. The results revealed that phenological parameters was significantly higher influenced days to 50% flowering, days to pod initiation and days to maturity recorded early sowing in 9 th February and the dose was increased 25% RDN followed by 100% RDN and lowest 75% RDN was observed. It strength be due to well disseminated rainfall received during the cropping period.
