    EFFECT OF FERTIGATION AND DRIP IRRIGATION ON PRODUCTIVITY OF TOMATO UNDER PROTECTED ENVIRONMENT.
    (CSK HPKV, Palampur., 2019-07) Singh, Jaspreet; Sandal, Sanjeev K.
    The present study was conducted at experimental farm of CSKHPKV, Palampur during the year 2018 with the objectives to study the effects of fertigation and drip irrigation schedule on soil, water productivity, crop productivity and NPK uptake. The treatments comprised of two drip irrigation levels DI1 (drip irrigation applied from week 1 to 2 @ 1.0 PE, week 3 to 8 @ 0.4 PE, week 9 to 14 @ 0.6 PE, week 15 to 20 @ 0.8 PE, week 21 to 24 @ 1.0 PE) and DI2 (Drip irrigation applied @ 1.0 PE from week 1 to till harvest) with five nutrient schedules viz., T1 100 % NPK applied through conventional method (C), T2 (C + 100 % N fertigation), T3 (C + 100 % NK fertigation), T4 (C+ 100 % NPK fertigation) and T5 (50 % NPK applied through Conventional method + 150 % through NPK fertigation). The tomato (lycopersicum esculentum) crop was transplanted on April 20, 2018. The results indicated that the soil water content and soil water stock was higher under DI2 and lower under DI1 treatments. The plant height and relative leaf water content (RLWC), biological yield and fruit quality parameter (titrable acidity) and root length were significantly higher under DI2 and lower under DI1 treatments. Among nutrient schedules, plant height, root weight, root length, ascorbic acid, titrable acidity, total soluble solids, biological yield, total NPK uptake were significantly higher under T5 and lower under T1. However, the root volume was significantly higher under T3 and lower in T1. The gross return was highest under T5D2 and lowest under T1D1. The B: C ratio was highest in T3D2 and lowest under T1DI1.The study concluded that the drip irrigation level DI2 (Drip irrigation applied @ 1.0 PE from week 1 to till harvest) and fertigation treatment T5 (50 % NPK through applied conventional method + 150 % through NPK fertigation) were the optimum treatments for obtaining maximum crop productivity.
