GROWTH, YIELD, ECONOMICS, WATER AND NUTRIENT USE EFFICIENCY OF POTATO AS INFLUENCED BY DIFFERENT METHODS OF DRIP FERTIGATION AND VARIETIES
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 38
Abstract
Field experiments were conducted during rabi season in 2011-12, 2012-13 to 2014-15 to study the effect of different methods of drip fertigation and varieties on growth, yield, water and nutrient use efficiency and economics of potato. Results showed that drip fertigation of 100% of recommended dose of N and K at 9, 16, 23, 30, 37 43, 51, 58 and 65 days after planting markedly increased growth attributes like plant emergence and plant height and ultimately gave significantly higher>75 g grade and total tuber yield of potato over conventional method. Further, this method had improved crop productivity, water and nutrient use efficiency along with more net return and benefit-cost ratio, which was much higher than conventional method. Although, Kufri Pukhraj registered highest total tuber yield, with slightly higher crop productivity, water and nutrient use efficiency, net return and benefit-cost ratio, the difference between varieties of potato was non-significant.
