Effect of Calcium in the Form of Gypsum on Growth, Yield and Quality of Potato (Solanum tuberosum L.)

The experiment was carried out at Horticulture Farm, Department of Horticulture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during the rabi 2010–2011. Treatment T₅-80 kg ha⁻¹ full dose of gypsum produced significantly higher plants emergence as well as number of shoot, number of leaves, and fresh weight of plant. Treatments T₇ and T₈ significantly lowest regards morphological traits, yields attributes and quality parameters. Tuber yields grades wise (0-25g, 25-50g, 50-75g, >75 g) per hectare and total tuber per hectare was observed significantly highest in T₅-80 kg ha⁻¹ FDG and number of tuber grades wise per hectare (0-25g, 25-50g, 5075g, >75g) and total number of tuber per hectare was also observed significantly highest in under T₅-80 kg ha⁻¹ FDG. The skin damaged tuber yield per hectare and skin damaged tuber number was found significant lowest in under T₅-80 kg ha⁻¹ FDG. Under the treatments combinations T₄-60 kg ha⁻¹ FDG, T₆-100 kg ha⁻¹ FDG, T₁₁-50 kg ha⁻¹ SDG and T₁₀-40 kg ha-¹ SDG performs better regards vegetative character, yields attributes and quality parameters. In T₅-80 kg ha⁻¹ FDG given better response related to during storage at 30, 60, and 90 days after harvest found that lowest rotted tuber, tuber weight loss and skin damaged tuber number and weight. The treatment combination 5 (T₅-80 kg ha⁻¹ FDG) and with recommended NPK @ 150:100:100 found remarkably superior to all the other treatment combinations as regards to all morphological traits, yields attributes, and quality parameters.
