Title: Yield and water use efficiency of groundnut (Arachis hypogaea L.) cultivars as influenced by time of sowing under irrigated and rainfed conditions in central Punjab
Abstract: A field study was conducted during three consecutive kharif seasons of 2004, 2005 and 2006 to evaluate the water use efficiency (WUE) of groundnut cultivars viz, M-522 (V1) and M-548 (V2) sown on three dates (D1: 1st June, D2: 20th June and D3: 10th July) under irrigated (I1) and rainfed (I2) conditions in central Punjab. Soil water extraction was found higher under irrigated as compared to rainfed crop for both the cultivars. Dry matter production and seed yield were also found higher under irrigated conditions except under first date of sowing during kharif 2005 and 2006, as higher amount of rainfall was received during these two years as compared to kharif 2004. Among different dates, higher pod yield was obtained from the 20th June sown crop. Water use efficiency for pod yield ranged between 1.7 to 4.7, 1.8 to 3.6 and 1.9 to 4.1 kg ha−1 mm−1 during three consecutive kharif seasons of 2004, 2005 and 2006. Among the varieties, water use efficiency was found to be higher for M-522 as compared to M-548, however, the difference was narrowed down during second and third year, when the amount of rainfall increased. The study indicates that only M-522 performed better under less rainfall conditions, whereas under high rainfall, the performance of M-548 was also improved.
