Abstract
Planting density is the most active factor and plays pivotal role in crop management practices. Hence plant density is the enduring topic for crop production improvement. The rational plant population is an important attribute to high yield of cotton, because it can provide a beneficial micro-environment within the canopy for plant growth and development as well as yield formation. A field investigation was carried out at the field of All India Coordinated Research Project on Agro-meteorology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MS) during Kharif season of 2015-16.Three cotton genotypes viz. G.hirsutum cotton AKH-081, G. arboretum cotton AKA-7 and G. hirsutum hybrid Bt. cotton Balwan with three plant densities with the population level of 100,150and 200 per cent of normal for respective genotypes were laid out in Factorial Randomized Block Design with three replications. The results revealed that, cotton genotype G. arboreum AKA-7 with 150 to 200 per cent planting density recorded maximum fraction of PAR, lowest fraction of transmitted PAR and canopy temperature with high canopy temperature depression and greater tolerance to environment stress with comparative to genotypes AKH-081 and Bt. cotton Balwan recorded significantly higher number of picked bolls, boll weight, higher seed cotton weight and harvest index (17.59 g, 3.21 g, 56.49 g and 39.50 %) as compared to genotype AKA-7 and genotype AKH-081. However, AKA-7 registered significantly higher seed cotton yield, cotton stalk yield and biological yield (1715, 3038 and 4753 kg ha-1) than Bt. cotton Balwan and hirsutum cotton genotype AKH-081. Normal plant density recorded higher number of picked bolls plant-1, seed cotton weight plant-1 (11.67 and 33.97 g) which are significantly more over high planting density of 150 and 200 per cent of normal population. However, normal planting at 100,150 and 200 per cent population was recorded being at par. High density planting (200 per cent of normal density) produced maximum seed cotton yield, cotton stalk yield and biological yield i.e.1802, 3338 and 5140 kg ha-1, respectively. Whereas, high density planting at 100 per cent of normal density produced maximum harvest index (38.08 %) which are significantly higher than 200 per cent high density planting (35.07%) an statistically at par with high density planting of 150 per cent. Different cotton genotype as well as plant density were statistically not significant in respect of quality studies of cotton.
