Abstract
The experiment was conducted at N.E. Borlaug Crop Research Centre of G. B. Pant University ofAgriculture and Technology, Pantnagar, Uttarakhand during Rabi season of 2021-22 to study on saving of water, soil properties and yield in pea (Pisum sativum L.) with the use of surfactant and different nutrient inputs. Five treatments viz control (T1), vermicompost + irrigation (T2), NPK + irrigation (T3), vermicompost + irrigation with surfactant (T4) and NPK + irrigation with surfactant (T5) were tested in field condition and water use studies were done under three water table regimes W1 (30 ± 1.5 cm), W2 (60 ± 1.5cm) and W3 (90 ± 1.5 cm) in lysimeters. It is clear from the results that the treatment of vermicompost + irrigation with surfactant (T4) resulted in maximum plant height (37.0 cm), number of branches per plant (13.3), number of pods per plant (4.7), pod length (8.3 cm), number of grains per pod (8.3) and yield of green pods (110.1 q/ha) in field condition. Maximum soil organic carbon content (0.76 %), available nitrogen (254 kg/ha), infiltration rate (32.1 mm/hr) and lowest bulk density at 0-20cm (1.18 Mg/m3) and 20-40 cm (1.30 Mg/m3) were also observed under treatment T4. However, available phosphorus (21.42 kg/ha), potassium (154.80 kg/ha) and EC (0.15 dS/m) were recorded maximum under T5 treatment. The application of vermicompost and irrigation with surfactant positively influenced the yield of vegetable pea and important soil physical & chemical properties. In Lysimeter, all yield attributes and yield of vegetable pea were recorded maximum (98.29 q/ha) under the water table depth of W1 (30 ± 1.5 cm). The highest WUE of 33.41 kg/ha/mm was recorded under W3 followed by W2 (27.05 kg/ha/mm) and then W1 (26.36 kg/ha/mm).
