Comparative performance of cotton genotypes under different soil depth

摘要

Field experiments were conducted from 1993 to 1996, to study the performance of G. arboreum, G. hirsutum and intrahirsutwn hybrids genotypes under medium (< 60 cm soil depth) and deep (> 60 cm soil depth) soils. Results revealed that on deep soils hybrid JKHy-1 exhibited superior over all types of G. arboreum and G. hirsutum, though it appeared at par to JKHy-2. G. arboreum varieties viz. Jawahar Tapti and Maljari performance better in all types of soils in comparison to G. hirsutum varieties Khandwa-3 and LRA-5166. Similarly the pooled data on seed cotton yield was found to be increased by 4.78 per cent of G. arboreum, 13.21 per cent G. hirsutum and 30.83 per cent intra hirsutum hybrids when grown on deep soils as compared to medium soils.
