Plant Density and Genotype Evaluation for High Density Planting System of Cotton under Rainfed Condition

Year: 2020

Type: article

Abstract: A field experiment was conducted to evaluate optimum plant density and suitable G. hirsutum cotton genotype for high density planting system under rainfed condition. Plant growth parameters, seed cotton yield and economics of cotton genotypes under various high planting densities were studied during kharif, 2013-14 to 2015-16 on medium soil. Increase in plant density has reduced monopodial branches plant-1 whereas, number of bolls plant were increased with increase in density. The plant density of 1.66 lakh plants ha-1 (spacing 60 x 10 cm) resulted in higher seed cotton yield (1705 kg ha-1) and net monetary returns (Rs. 40,496/- ha-1). The hirsutum cotton genotypes NH 615, NH 635 and Suraj were found suitable for high density planting system as exhibited greater number of bolls plant-1, yield plant-1, seed cotton yield ha-1 (1742 kg ha-1 and 1683 kg ha-1, respectively) and monetary returns. The genotype Suraj was found to be high ginner (37.40 per cent) followed by NH 615 (37.35 per cent).
