Effect of INM on growth and yield components of Brinjal (Solanum melongena L.) under Teak (Tectona grandis L. f.) based silvi-horticultural system in South Gujarat region

Abstract

The experiment entitled “Integrated nutrient management of Brinjal (Solanum melongena L.) Under Teak (Tectona grandis L. f.) based Silvi-horticultural system in South Gujarat region” was carried out at College Farm (Block-A, Plot No-21), N. M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat during the year of 2016-17. A Brinjal (Solanum melongena L.) Variety – Surati Ravaiya was grown under twenty three years old plantation of Teak (Tectona grandis L. f.) planted at 3m X 2m spacing. Growing of brinjal crop in open condition resulted in significant increase in various growth as well as yield parameters as compared to growing brinjal crop under INM treated teak based Silvi-horticultural system. The significantly maximum plant height (73.90 cm) and number of branches per plant (5.33) were noted in T14: 100% RDF in open condition. Similarly, various yield parameters viz., number of fruits per plant (24.89), fruit circumference (14.14 cm), fruit length (8.64 cm), average fruit weight (45.64 g) and yield (20357.35 kg/ha) were also recorded significantly maximum in T14: 100% RDF in open condition. The same treatment was remained at par with 75 % RDF along with different organics for majority of growth and yield parameters. Moreover, INM treatment of T2: Azotobactor alone under teak based Silvi-horticultural system reported minimum growth and yield parameters. The slight reduction was registered in INM treated teak based Silvi-horticultural system as compared to open condition.
