Performance of Different Varieties of Brinjal( Solanum melongena L.) under Young Plantation of Gamhar( Gmelina arboreal Roxb.)

Abstract

The investigation entitled “Performance of different varieties of Brinjal (Solanum melongena L.) under young plantation of Gamhar (Gmelina arborea Roxb.)” was carried out at Instructional Farm, College of Forestry, Navsari Agricultural University, Navsari, Gujarat, during Summer 2022. In this experiment, four varieties of Brinjal viz.; V1: GNRB – 1, V2: Swarna Mani, V3: Surti Ravaiya, V4: GAOB – 2 with RDF (100:50:50 NPK/ha) were grown in open condition and under Gamhar (G. arborea Roxb.) with three repetitions in Factorial Completely Randomized Design.

Among four varieties, variety V1 performed well for plant height (96.27 cm), number of branches per plant (8.67), number of fruits per plant (23.28), fruit yield per plant (1.36 kg), fruit yield per plot (17.15 kg) and fruit yield per hectare (48353.91 kg), however, V4: GAOB showed better performance for earlier flowering (43.23 days). Between two growing conditions, maximum plant height (85.44 cm), number of branches per plant (7.32), number of fruits per plant (20.27), fruit yield per plant (1.14 kg), fruit yield per plot (14.57 kg) and fruit yield per hectare (37233.02 kg) were noted in sole crop as compared to agroforestry (G. arborea + Brinjal) system.

The combined effect of variety and growing conditions had not any significant effect on plant height, number of branches per plant, days to first flowering, number of fruits per plant,fruit yield per plant, fruit yield per plot and fruit yield per hectare.

The V1: GNRB – 1 grown in sole condition gave highest net realization (₹ 4,60,899.90) and BCR (3.86). On the basis of present findings, it is recommended that growing of Brinjal crop under young planation of Gamhar can provide sustained and additional income to the farmers.
