EFFECT OF DIFFERENT FERTILITY LEVELS ON TUBER YIELDS, INPUT USE EFFICIENCY AND ECONOMICS OF POTATO VARIETY KUFRI CHIPSONA-3

Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 49

Abstract

A field study on different levels of NPK i.e.,-0-0, 165-84-165,330-168-330, 495-252-495 and 660-336-660 kg N-P2O5-K2O/ha were conducted on processing potato variety Kufri Chipsona-3 at Potato Research Station, SDAU, Deesa (Gujarat) during rabi season for two consecutive years 2012-13 and 2013-14. Results clearly revealed that application of 330-168-330kg N-P2O5-K2O/ha had significantly higher tuber yield (23.13 t/ha) over lower dose of NPK (165-84-165kg N-P2O5-K2O/ha), while reducing tuber cracking than higher doses of NPK (495-252-495 and 660-336-660 kg N-P2O5-K2O/ha). Nutrient use efficiency of NPK decreased with subsequent increase in levels of NPK, while water use efficiency and crop productivity registered significant improvement under elevated doses of NPK up to 330-168-330 kg N-P2O5-K2O/ha. From economic point of view, 330-168-330kg N-P2O5-K2O/ha registered highest net income (₹27,032/ha) and return per day (₹275.84/ha/day).
