英文摘要	Peanut cultivation during the summer needs precise management of nutrient and water resources particularly in arid and semi-arid areas to sustain agricultural productivity where water is a scarce commodity. Application of NPK fertilizers both normal and water-soluble was evaluated using soil and drip fertigation methods for their effect on productivity, profitability, enzyme activities, and soil nutrient balance. Application of 100% NF at sowing through drip irrigation (T-10) significantly (p =.05) enhanced leaf area index (LAI), yield attributes, pod, kernel, and oil yields, and net returns over T-1, which was found at par to the staggered application of 75% or 100% water-soluble fertilizers (WSF) through drip except for net returns at T-5 and T-8. However, the highest plant height, dry weight, and haulm yield was observed under T-4. The highest PFP was recorded with treatment T-6 and showed a declining trend with an increase in fertilizer dose. Activities of phosphatase enzymes increased up to 60 DAS and thereafter, showed a declining trend except for alkaline phosphatase under T-1. Significantly higher dehydrogenase activity was reported under T-9 at 60 DAS except under T-1 and T-6. Compared to initial status, actual available N, P, and K status after harvest increased in all the treatments but maximum actual gains were recorded under T-1. The results clearly indicated that pod yield and net returns obtained under treatments T-2 to T-9 were comparable to T-10 except for net returns at T-5 and T-8. Therefore, 25% NPK requirement could be saved without affecting yield and net returns with treatment T-6 in the summer peanut.
