Effects of sowing windows on gradewise yield of tubers of potato

Abstract

The field trial was conducted during both the seasons (2009-10 and 2010-11) on PGI Farm without changing randomization. The experiment was laid out in rabi season. The various components of yield and yield contributing characters were calculated. The growth and yield contributing characters, small (19.28 and 16.99 q ha-1), medium (123.94 and 50.97 q ha-1), large sized (132.20 and 271.81 q ha-1), pooled yield (307.59 q ha-1) and pooled haulm yield (12.23 q ha-1) were higher in 1.2 IW/CPE ratio (5 irrigations at 18 to 20 days interval) and planting on 44th MW (Oct 29-Nov 04) with sugarcane trash mulch as compared to other treatments.
