Studies on the effect of micronutrients and biofertilizers on seed production of brinjal (Solanum melongena L.) var. Kashi Taru under Chhattisgarh plain condition

Abstract

The present investigation "Studies on the effects of micronutrients and bio-fertilizers on seed production of Brinjal (Solanum melongena L.) var. Kashi Taru under Chhattisgarh Plain condition," was conducted at Indira Gandhi Krishi Vishwavidyalaya, Krishi Vigyan Kendra, Raipur farm, C.G. during the year of 2022-23 and 2023-24. A randomised complete block design with three replications was used to set up this experiment. Thirteen treatments combination of three micronutrients ZnSO4, FeSO4 and Borax via foliar application at 30, 40, 50 days after transplanting and two biofertilizers i.e. PSB, Azotobacter @ 2 l/acre through soil drenching technique, including control (RDF 100%) had designed. The experiment was comprised of thirteen treatment i.e., micronutrients sole with 100% RDF and biofertilizers and micronutrients in different combination with 75% RDF. According to the study, application of treatment T13 (ZnSO4 0.2% + Borax 0.1% PSB + AZ + RDF 75%) was found highly significant on yield attributes and seed yield and its quality traits viz., no. of fruits per plant, average fruit weight (g), fruit length (cm), fruit girth (cm), number of seeds per fruit, seed yield per fruit (g), seed yield per plant (kg), seed yield per hectare (kg ha-1), 1000 seed weight (g), germination %, seedling length (cm), radicle length (cm), plumule length (cm), and seedling vigour index-I during the year of 2022-23 and 2023-24. Where seedling dry weight (mg) and seedling vigour index-II was recorded non-significant during both the season. The findings showed that yield attributes and seed yield and its quality parameters of brinjal var. Kashi Taru were found to be significantly increased with the application of T13 (ZnSO4 0.2% + Borax 0.1% + PSB + AZ + 75% RDF) followed by T12 (FeSO4 0.2% + Borax 0.1% PSB + AZ + RDF 75%). Whereas the minimum values for above parameters were recorded under T1 (control).
