The experiment entitled “Studies on effect of age of rootstock and scion on success, survival and growth of brinjal grafts” was carried out in 2018-19 to standardize the age of scion and rootstock seedlings for grafting which consists of nine treatment combinations viz.T1: 20 days old scion grafted on 20 days old rootstock, T2: 25 days old scion grafted on 20 days old rootstock, T3: 30 days old scion grafted on 20 days old rootstock, T4: 20 days old scion grafted on 25 days old rootstock, T5: 25 days old scion grafted on 25 days old rootstock, T6: 30 days old scion grafted on 25 days old rootstock, T7: 20 days old scion grafted on 30 days old rootstock, T8: 25 days old scion grafted on 30 days old rootstock, T9: 30 days old scion grafted on 30 days old rootstock and each treatment was replicated thrice in Randomized Block Design.The brinjal cultivar Swarn Pratibha was used as rootstock and Kali-rawai was used as scion. Less number of days (7.60) were required for graft union in T1 whereas highest number of days (8.20) were required for graft union in T6. Highest grafting survival (75.33%) at 30 DAG was observed in treatment T5 whereas lowest grafting survival (70.67%) at 30 DAG was observed in treatment T3 and T7.
The present investigation was carried out to study the effect of season on the survival and growth of Hibiscus cuttings in konkan agro-climatic condiation under polyhouse at Hi-tech project of Dr. Balasaheb Sawant Konkon Krishi Vidyapeeth, Dapoli during January 2018 to December 2018. Propagation through semi-hardwood cuttings of Hibiscus, the cuttings were planted in season such as T1: January, T2: February, T3: March, T4: April, T5: May, T6: June, T7: July, T8: August, T9: September, T10: October, T11: November, T12: December and the experiment was conducted in randomized block design with twelve treatments and three replications. The maximum survival and sprouting percentage, leaf area, length of sprout were recorded in the treatments T2 (February). It can be concluded that propagation through semi-hardwood cuttings in the treatment T2 i.e. February month had proved to be the best month for propagation under polyhouse conditions in konkon conditions of Maharashtra.
