Effect of calcium application on yield and post harvest qualities of potato

Abstract

Three years of studies were conducted at Potato Research Station, SDAU, Deesa, to study the effect of calcium application in the form of gypsum on yield and post-harvest qualities of potato cv. Kufri Badshah. Results revealed that calcium application did not have a significant influence on the growth and yield of potato. However, application of 80 kg/ha calcium at the time of planting in the form of gypsum enhanced net returns, benefit-cost ratio, and percentage dry matter of tubers over the rest of the treatments. Post-harvest studies indicated that split application of 40 kg/ha calcium during planting and 40 kg/ha calcium at earthing up reduced tuber weight loss, number of sprouts, and rotting of tubers during 90 days of storage.
