Abstract:In the
rabi season of 2019-2020, research entitled “Studies on water requirement of different wheat genotypes grown under irrigation (
Triticum aestivum L.)” was carried out at the farm of Wheat Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). The treatments entailed of 15 treatment combinations comprised of three irrigation levels i.e., two irrigation (CRI, Flowering), four irrigation (CRI, Tillering, Flowering and Milk stage), six irrigation (CRI, Tillering, Jointing, Flowering, Milk and Dough stage) and five wheat genotypes
viz., AKAW-4627, AKAW-4832, WSM 109-4, PDKV SARDAR, and PDKV WASHIM. Three replications of a factorial randomized block design were used to set up the experiment. The soil had a pH of 7.64, was clayey, and had 212.72, 22.27 and 368.45 kg ha
-1 of readily available N, P and K.
Consumptive use of water was highest in six irrigation that were irrigated frequently. Maximum water productivity and water use efficiency were observed under two irrigations (CRI, Flowering) with genotype AKAW-4627. Under six irrigation scenarios, the genotype AKAW-4627 produced the highest gross monetary returns, net monetary returns, and benefit cost ratio (CRI, Tillering, Jointing, Flowering, Milk and Dough stage).
