At the Crop Research Farm, Department of Agronomy, SHUATS, Allahabad (U.P.). A field experiment was undertaken during the Zaid season (2021-22). The soil texture of experimental plot was sandy loam, soil pH 7.1, less in organic carbon (0.28 %), available N (225 kg/ha), available P (19.50 kg/ha) and available K (213.7 kg/ha). IR1 (Irrigation at 25DAS), IR2 (Irrigation at Vegetative Stage (35DAS)), IR3 (Irrigation at Vegetative(35DAS) and Pod Formation Stage (55DAS)) were different 3 irrigation scheduling, and (20 kg/ha), (40 kg/ha) and (60 kg/ha) were different 3 levels of Phosphorus. The experiment was conduct in Randomized Block Design with nine treatments and was repeated three times. The result displayed the application of Irrigation at Vegetative (35DAS) and Pod Formation(55DAS) +60Kg P/ha topmost plant height (41.70 cm) recorded in research, Number of nodules/plant (5.90), plant dry weight (11.00 g/plant), pods/plant (40.30 cm), number of seeds per pod (6.80), length of pod (8.40), test weight (36.00 g), grain yield (854.08kg/ha), straw yield (1928.70 kg/ha) and harvest index was non-significant. Highest Gross retunes (59017.7 INR/ha), Net retunes (37832.3INR/ha) and B:C ratio (1.78) also recorded in treatment 9 with apply Irrigation at Vegetative (35DAS) and Pod Formation(55DAS) +60Kg P/ha. Improper Irrigation scheduling and phosphorus application is bigger challenges for Indian farmers to decreases productivity of green gram. Presently the farmer they are given the irrigation as an when they give the water through the canal, there for due to over irrigation in field that they get less yield, but If we give irrigation scheduling in critical growth stages so we can save the number of irrigation and increase the yield of green gram. Application of higher levels of phosphorus was also showed maximum in growth and yield during such as root development, pod maturity, increases the weight of pods, dry weight and seeds per plant so that production can be increased. So that with combination of both irrigation scheduling and phosphorus level we can expect maximum production in green gram.

Irrigation, Growth, Yield, phosphorus, Zaid

On the basis of one season experimentation it can be concluded that with the application of Irrigation at Vegetative (35DAS) and Pod Formation (55DAS) + 60Kg P/ha was found significantly superior in Pods/plant (40.30), Seeds/pod (6.80), Test weight (36.00 g), Grain yield (854.08 kg/ha), Stover yield (1928.70 kg/ha)and economically viable (1.78) so this treatment is viable for farmers
