Effect of Drip Irrigation and Fertigation on Soil Water Dynamics and Productivity of Greenhouse Tomatoes

The proficient supply of water and nutrients is a key factor for successful vegetable production under greenhouses. This field experiment was conducted during 2018–2019 completely randomized design to evaluate the effects drip irrigation nutrient schedule on soil dynamics productivity greenhouse tomato. consisted two schedules, i.e., I1 (irrigation applied from week 1 2 basis 100% pan evaporation (Epan), 3 8 40% Epan, 9 14 60% 15 20 80% 21 24 Epan) I2 Epan throughout crop period) with five-nutrient schedule, viz., F1 (100% NPK through conventional method), F2 N fertigation + PK F3 NK P F4 fertigation) F5 (50% method 150% fertigation). moisture content (SMC) its depletion were measured growing season. tomato yield significantly higher I2. However, use efficiency (WUE) treatment. Among WUE in net returns highest lowest F1. Benefit:Cost ratio level treatment best strategy obtaining maximum greenhouse. It can be concluded that drip-based enhances therefore may promoted increase income farmers.
