A field experiment was conducted during kharif season of 2008-09 to study the effect of crop geometries and fertility levels on growth, yield and residual nutrients of cotton (Gossypium hirsutum L.) hybrids under rainfed condition. Cotton hybrids MLCH 318 was planted under wider crop geometry of 90 cm × 60 cm which recorded significantly higher growth parameters, monopodial branches and seed cotton weight/plant. However, yield potential of MLCH 318 were higher under closer crop geometry (60 cm × 60 cm) and recorded significantly taller plant, yield attributes and yield of cotton over wider crop geometry of 90 cm × 60 cm (S1) due to more number of plants stand at initial and harvest stages, respectively. Although, cultivar VBCH 2231 (V2) with crop geometry of 90 cm × 60 cm (S1) recorded more in residual status of N (200.44 and 204 kg/ha), P (16.82 and 16.67 kg/ha) and K (496.50 and 489.04 kg/ha), respectively. Among fertility levels, growth characters, yield attributes and yield of cotton with residual N (204.11), P (17.24) and K (495.26 kg/ha) were significantly higher under highest levels of fertility, i.e. 62.5: 31.25: 31.25 kg N: P: K/ha. Thus, it concluded that sowing of cultivar MLCH 318 at crop geometry of 60 cm × 60 cm and fertilized with. 62.5: 31.25: 31.25 kg N: P: K/ha produced significantly higher yield attributes and yield under rainfed condition.

The field experiment consisted of two crops geometry (S1-90 × 60 cm and S2- 60 × 60 cm), three cotton hybrids (V1-MLCH-318, V2-VBCH-2231 and PKV Hy-2) and three levels of NPK (F1-37.5: 18.75: 18.75, F2-50: 25: 25 and F3-62.5: 31.25: 31.25 kg N:2O5:K2O/ha). Closer crop geometry of 60 X 60 cm significantly produced more plants population (271.51 '00'/ha and 242.77 '00'/ha at initial and harvest, respectively), lint yield (345 kg/ha), seed cotton yield (910 kg/ha) and stalk yield (1058 kg/ha) with uptake of N (40.39), P (14.78) and K (46.59 kg/ha) over wider crop geometry of 90 × 60 cm (S1). Among hybrids, MLCH-318 (V1) showed significantly superiority to VBCH-2231 (V2) and PKV Hy-2 (V3) in respect of lint yield (407 kg/ha), seed cotton yield (1034 kg/ha) and stalk yield (1054 kg/ha). MLCH-318 (V1) when sown at crop geometry of 60 × 60 cm recorded the highest uptake of N (41.47 and 40.39), P (15.08 and 14.78) and K (48.01 and 46.59 kg/ha) with total uptake of NPK (104.56 and 101.76 kg/ha), respectively. The application of 62.5:31.25:31.25 N:P2O5:K2O/ha produced the maximum lint yield (393 kg/ha), seed cotton yield (972 kg/ha), stalk yield (988 kg/ha) and recorded higher uptake of N (40.33), P (15.08), K (46.81 kg/ha) and total uptake of NPK (102.22 kg/ha). The interaction effect between hybrids and crop geometries was found significant.
