Title : PERFORMANCE OF DIFFERENT GRAFTED VARIETY AND MULCHING IN BRINJAL (Solanum melongena L).

Abstract :

A field experiment on grafting three cultivars of brinjal, namely GJB-3, GAOB-2 and Suratiravaiya onto the rootstock of Solanum torvum Swartz was conducted to find out the interaction effect of different grafted and non-grafted varieties and different mulching on plant survival and other horticultural parameters. The variation due to different mulching treatment was found significant for growth and yield parameter. Significantly, highest plant height (113.80) cm), No. of branches per plant (8.97), No. of fruit per plant (12.94), average fruit weight (86.26 gm), marketable fruit yield (1.10 kg/plant and 29.76 t/ha) and lowest days to 50% flowering at TP (49.30), days to first picking (67.96) and days to last picking (173.20) were recorded in treatment M2 (Silver Mulch). Similarly, variety variation was observed significant for growth, yield and yield attributes. Significantly, maximum average fruit weight (107.73 gm), marketable fruit yield, (1.25 kg/plant and 34.78 ton/ha) were recorded with variety (V1): GJB-3 grafted on solanum torvum, whereas, highest plant height (121.18 cm), no. of branches/plant (9.95) and no. of fruits per plant (15.68) were noted in V3: Surtiravaiya grafted on solanum torvum and lowest days to 50% flowering (43.94%), days first picking (67.28) and days to last picking (170.56) were registered with V2 (GJAB-2 grafted on solanum torvum). Interaction effect was found non-significant for maximum character except no. of branches/ plant, no. of fruit per plant and marketable fruit yield. Variation between treatments of mulching was recorded significant for quality and insect pest infestation parameters. Significantly, highest TSS (7.67oB), plant survival (87.59%) and lowest acidity (0.171%), fruit and shoot borer, jassid and white fly infestation (23.24%, 21.81% and 63.59% respectively) were registered with M2 (Silver mulch). For varieties, variation was recorded significant for quality and insect pest infestation parameter. Maximum TSS (8.24oB), minimum acidity (0.102) and fruit and shoot borer infestation (19.72%) were recorded with V3. Whereas, highest plant survival (92.00%) and lowest Jassids and white fly infestation (15.11% and 62.67%) were noted in V2. Interaction effect for quality and insect pest infestation parameters were noted non-significant except TSS and acidity. The farmers of South Saurashtra Agro-climatic Zone growing brinjal are recommended to use variety GJB-3 grafted on Solanum torvum (wild brinjal) with silver black mulch (25 micron) for higher yield.
