Abstract
A field experiment was conducted during rainy (kharif) season of 1993 and 1994 at Indore, to evaluate the productivity of different plant types (KH 100-2237 l and 79 BH 5-3) of upland cotton (Gossypium hirsutum L.) under various fertility levels (i.e. 40 20 l0,60 30 : 15 and 80 40 20 kg N : : : : : : : P Wha) and planting geometries (60 cm x 30 cm, 60 cm x 45 cm and 60 cm x 60 cm). KH 100-2237 had higher cotton yield, lint yield, bollslplant and yieldlplant but significantly low seed and lint index. Plant spacing did not have significant effect on seed-cotton yield, lint yield, boll size and physical parameters. However, closer intra-row - planting gave numerically higher seed-cotton yield than wider inter-row spaced crop at 60 cm x 60 cm, but reverse trend was noted for bollslplant and yieldlplant. Application of 80, 40 and 20 kg N,P and Wha recorded significantly higher yield of cotton, lint yield and seed index. However, the various F levels did not have any impact on yield attributes.
