Field experiment was conducted to study the performance of potato CV. Kufri Khyati to aberrations of temperature and rains in relation to production and incidence of disease and pests at Central Potato Research Station, Gwalior, India. Potato cultivar Kufri Khyati was planted with four planting windows viz 15th September, 30th September, 15th October and 30th October for three consecutive years during 2009-10, 2010-11 and 2011-12. Data revealed that early planting of potato CV. Kufri Khyati at higher temperature delayed tuberization, reduced tuber number (259,000/ha) and finally there was a drastic reduction in tuber yields (9.5 t/ha) with net returns showed negative (Rs 14612/ha) trend. The B: C ratio was also less than 1 in 15th September planted crop along with higher incidence of mite, thrips and stem necrosis disease. The highest N uptake (92 kg/ha) was recorded with 15th October planted crop, however it was lowest with 15th September planted crop. The highest nitrogen use efficiency (182 kg tuber/kg N applied) and water use efficiency (109 kg tuber/mm water) was recorded with 15th October planted crop with low incidence of pests and diseases. Severe mite, thrips and stem necrosis disease incidence were recorded in 15 and 30th September planting window of potato. Thus, the planting window of 30th October is the most suitable planting date for potato cv. Kufri Khyati for ware crop to get maximum tuber yield, low incidence of mite and thrips and higher net profit in Central India.
