Abstract:
The present investigation deals with the effects of foliar spray treatments on growth characters, biochemical attributes, yield attributes and quality parameters by using four growth regulators viz., Salicylic acid @ 200 ppm, Brassinosteriods @ 0.1 ppm, Triacontanol @ 5 ppm and NAA @ 40 ppm, and four organics viz., Seaweed extract @ 1.0%, Humic acid @ 1.0%, Panchagavya @ 5.0% and Vermiwash @ 5.0% were tested as foliar spray treatments in brinjal cv VRM-1. Water spray also was given as control treatment. Panchagavya treatment recorded maximum values in number of leaves, number of flowers per plant and number of fruits per plant. Panchagavya treatment as the best performing treatment among the foliar spray treatments in terms of fruit yield per plant. Next to Panchagavya treatment, foliar spray of Vermiwash produced maximum values on number of branches. Seaweed extract and Vermiwash sprays were found good in increasing ascorbic acid content in brinjal fruits. Triacontanol and Salicylic acid were effective in increasing total phenols. Humic acid and Seaweed extract treatment fared better in increasing total soluble solids.
