Abstract:
An experiment was conducted to assess the effect of planting dates on growth and yield response of potato Cv. Kufri Pukhraj at the Instructional Farm, Department of Horticulture, College of Agriculture, Latur, Maharashtra during September 2012 to March 2013. Eight planting times (September 30, October 10, October 20, October 30, November 10, November 20, November 30 and December 10) with a spacing of 60 x 15 cm were laid out in randomized complete block design with three replicates. The earliest planting date of 30^th September recorded maximum emergence percentage (at 15 and 20 DAP). Data revealed that the maximum height (52.93 cm and 70.23 cm) at 45 and 75 DAP respectively and maximum number of leaves at both 45 and 75 DAP was recorded in the tuber planted on 10^th October while the minimum values were observed on tuber planted on 10^th December. Further, the maximum number of tubers (8.20) per plant was recorded in planting date of October 10 which was at par with planting on 30^th October and 10^th November, while the minimum number of tubers (4.00) per plant was obtained in planting date of 10^th December. The highest yield (44.93 kg/plot and 27.74 t/ha) was recorded in planting date of 10^th October which was statistically at par with 20^th October planting_. While, the lowest yield (17.45 kg/plot and 10.77 t/ha) was observed in planting date of 10^th December. Study conclusively revealed that the potato crop planted on 10^th October recorded maximum plant height, number of leaves and yield.
