ABSTRACT
An experiment was conducted during kharif seasons of 2011-12, 2012-13 and 2013-14 at Experimental Farm of Division
of Vegetable Science, SKUAST Kashmir to explore the effect of calcium treatments on growth, yield and post-harvest traits of potato variety Shalimar Potato-1. Results revealed that the maximum tuber yield (38.12 t/ha) was recorded with the highest application of Ca at the planting time viz., 120 kg Ca/ha (T6), followed by T4 viz., application of 80 kg Ca/ha at the time of planting (36.24 t/ha). Tuber weight loss per 5 kg sample of each treatment was recorded at 30, 60 and 90 days. Maximum tuber weight loss (6.85%) was recorded with treatment T1 i. e. No application of Ca, while as minimum tuber weight loss at 90 days after storage (4.05%) was also recorded in treatment T6 . Maximum number of sprouted tubers (6) and minimum weight of sprouted tubers (0.32 kg) at 90 days after storage were recorded with treatment T1 viz., No application of Ca and minimum number of sprouted tubers (3) and minimum weight of sprouted tubers (0.11 kg) at 90 days after storage were recorded with treatment T6 viz., application of 120 kg Ca/ha at planting.
