Standardization of grafting time and height on success of softwood grafting in mango (Mangifera indica L.)

Abstract

The experiment was conducted at Sakkarbaug, Fruit research station, Department of horticulture, college of Agriculture, Junagadh Agricultural University, Junagadh during June 2015 to February 2016. The treatments comprised of six grafting times and three grafting height. The experiment was laid out in a Completely Randomized Design with factorial concept and three replications. Interaction effect was observed significant in majority of parameter except carbohydrate content, phenol content, days to shoot emergence, success percentage, survival percentage, length of taproot and girth of taproot. Significantly maximum shoot length and plant height were reported at 15th September grafting with 60 cm grafting height (T3H3). However, it was at par with treatment combination of 30th August with 60 cm (T2H3). While, maximum stock girth and leaves were recorded in 30th August with 60 cm (T2H3) followed by T3H3. Likewise, maximum scion girth was noted in treatment combination of 30th August with 40 cm (T2H2). Similarly, poor result in plant height, number of leaves and scion girth were reported in 30th October with 20 cm (T6H1). Whereas, lowest shoot length was noted in 15th October with 20 cm (T5H1) and lowest stock girth was also reported in 30th October with 40 cm (T6H2).
