Effect of different grafting dates and wrapping materials on increment in length and girth of scion and increment in length and girth of root stock of softwood grafting in custard apple (Annona squamosa L.) cv. GJCA-1 under Saurashtra condition

Abstract

An investigation was carried out to see the effect of different grafting dates and wrapping materials on success of softwood grafting in Custard apple (Annona squamosa L.) cv. GJCA-1 under Saurashtra condition during Feb- August of the year 2017 at Lalbaugh Farm, Department of Horticulture, College of Agriculture, Junagadh Agricultural University, Junagadh (Gujarat). The treatments comprised of seven different grafting dates and two different wrapping materials. The experiment was laid out in Completely Randomized Design with factorial concept and replicated three times. The results revealed that amongst different grafting dates and wrapping materials grafting done on 01.04.2017 with graft tied with degradable tape observed significantly maximum increment in length of scion (4.00%, 10.10% and 16.83%) at 30, 60 and 90 DAG (Table.2), maximum increment in length of root stock (1.30%, 3.95% and 5.84%) was recorded at30, 60 and 90 DAG (Table.3), maximum increment in girth of root stock (18.48%, 26.97% and 43.18%) was recorded at 30, 60 and 90 DAG (Table.3). While, grafting done on 15.03.2017 with graft tied with degradable tape recorded maximum increment in girth of scion (19.57%, 45.97% and 46.37%) was recorded at 30, 60 and 90 DAG (Table.2) when, as compared to other treatments.
