Effect of Irrigation and Fertigation Levels on Soil Fertility and Yield of Watermelon (Citrullus lanatus Thunb.)

Aims: To study the effect of different irrigation and fertigation levels as well their Indeterminate on soil fertility, nutrient uptake, fruit yield watermelon.
 Study Design: Strip-plot design.
 Place Duration Study: A field experiment was conducted at Department Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during summer season 2018-19 2019- 2020.
 Methodology: Two factors three in each factor nine combinations were evaluated against Results: The results revealed that pH reduced while organic carbon content increased with an increase levels. In general, pooled mean available nitrogen (N), phosphorus (P), potassium (K) higher by 4.8, 16.9, 4.5%, respectively, F1 (125% RDF through fertigation) over F3 (75% significantly maximum availability observed under treatment combination I2F1. uptake N, P, K I1 (100% water requirement (IWR)) about 12 22, 27 21, 32 31% level I3 (60% IWR) F3, respectively. data I2 (80% had 35.39 36% watermelon compared to Among levels, a I2F1, followed I2F2.
 Conclusion: demonstrated superiority combining I2F1 for improving fertility yield, potentially saving up 20% water.
