Abstract

The experiment was conducted with sixteen treatment combination using four planting dates (22nd October, 1st, 11th and 21st November) and four fertilizer doses (75; RFD1, 100; RFD2, 125; RFD3 and 150%; RFD4) of recommended dose (150:50:100 Kg ha−1 of NPK). The highest percentage of A-grade tubers and marketable yield was recorded with 1st November (D2) planting followed by 22nd October planting (D1), while the lowest values were recorded with 21st November (D4) planting. Percentage of D-grade tubers was highest in 21st November planting, indicating the decrease in tuber size (non-marketable) with delayed planting. Percentage of A and B grades, marketable and total tuber increased with increase in fertilizer dose. However, the percentage of C and D grade tubers decreased with fertilizer dose. Therefore, 1st November planting coupled with higher fertilizer dose may result in improved marketable yield under sandy loam soils.
