Abstract
An experiment entitled “Evaluation of brinjal (Solanum melongena L.) grafts for growth, yield and yield attributing characters” was conducted with the major objectives of monitoring the changes induced by different rootstock-scion combinations in terms of plant growth and yield of brinjal at Research block, Department of Vegetable Science, COH, Bengaluru, GKVK Post, Karnataka during the year 2017-18.
The experiment was laid out in Randomized Block Design with two brinjal hybrids Galine-F1 and Mahy-11 grafted onto seven different rootstocks and non-grafted were used as control. The highest graft success (96.67%) was recorded in T1 (Galine F1 grafted onto Solanum torvum Swartz). Overall vegetative growth was highest in grafted plants. Among different treatments, T1 ( Galine F1 grafted onto Solanum torvum Swartz ) recorded maximum plant height (93.00 cm). Maximum number of leaves (372.98) and number of branches (15.29) and number flowers per plant (41.55) was recorded in T7 (Mahy-11 grafted onto Solanum torvum Swartz). A positive effect of grafting was recorded when Solanum torvum Swartz was used as rootstock. The highest average fruit weight was recorded in T1 (Galine F 1 grafted onto Solanum torvum Swartz) (257.57 g). Galine F 1 grafted onto Solanum torvum Swartz (T1) recorded the highest fruit diameter, fruit length and fruit volume. Mahy-11 grafted onto Solanum torvum Swartz (T7) observed maximum number of fruits per plant (30.18) and yield per hectare (61.11 t/ha).
The cost of graft production was Rs. 4.14 /- and 4.12 /- per graft of Galine F1 and Rs. 3.61/- and 3.59/- per graft of Mahy-11 when grafted onto wild rootstock and cultivated rootstock respectively. The highest BC ratio (1 : 2.71) was recorded in T7 (Mahy-11 grafted onto Solanum torvum Swartz). Grafted Mahy-11 performed best in flowering and yield characters when Solanum torvum Swartz was used as rootstock.
