Abstract:
A field experiment was conducted during kharif 2013-14 in rainfed Vertisols of Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with a view to study the performance of cotton compact varieties under high density planting system with different spacings and varied sowing time intervals for higher production and to reduce the cost of cultivation under changing climatic conditions. The experiment was laid out in factorial randomized block design in four replications. Three compact varieties AKA-5, AKA-7 and AKA-8 were taken as main treatments with three spacings, 60cmX15cm, 45cmX15cm and 45cm X 8cm. The results revealed that AKA-5 genotype found significantly superior (120 DAS) in terms of leaf area (60.18dm2/ plant), leaf area index (3.55), total dry matter production (79.76g/plant), whereas, spacing 45cm x 8cm found significant in parameters like Plant height (134.95cm) at 150 DAS and leaf area index (3.83) at 120 DAS compared to spacings 45cm x 15 cm and 60cm x 15cm.
