Effect of season and environmental conditions on softwood grafting of sapota under Saurashtra region of Gujarat cv. Kalipatti

Abstract

An investigation on “Effect of season and environmental conditions on softwood grafting of sapota under Saurashtra region of Gujarat cv. Kalipatti” was carried out at Hi-Tech Horticulture Park, Department of Horticulture, JAU, Junagadh during the year 2019-20. The treatments comprised of three level of season (S) viz., S1 = February-March (Summer), S2 = June-July (Kharif), S3 = September-October (Winter) and three level of environmental conditions (C) viz., C1 = Open field, C2 = Net house, C3 = Polyhouse. The experiment was laid out in Completely Randomized Design (CRD) with Factorial concept comprising nine treatment combinations with three replications. The result indicated that among season June-July recorded minimum number of days required for emergence of sprout (11.72). February-March recorded highest success rate (56.94%, 59.72%, 59.72% and 59.72%) with minimum mortality (43.06%, 40.28%, 40.28%, and 40.28%), maximum survival percentage (56.94%, 58.00%, 55.56% and 55.56%) at 30, 60, 90 and 120 DAG, respectively. The result indicated that among environmental conditions polyhouse recorded minimum number of days required for emergence of sprout (10.34), highest success rate (40.17%, 44.00%, 44.00% and 44.00%), minimum mortality (59.83%, 56.00%, 56.00% and 56.00%) and maximum survival percentage (40.17%, 43.00%, 43.44% and 43.44%) at 30, 60, 90 and 120 DAG, respectively.
