Abstract

The variety MCU 5 and hybrid TCHB 213 both responded well for heavy doses of fertilizer levels, eventhough the response to fertilizers was felt much in MCU 5 than TCHB 213. Comparatively more seed cotton yield and seed yield were obtained by a fertilizer dose of 200:150:100 NPK kg ha'. For this levels of NPK, MCU 5 and TCHB registered 2588 and 2750; 1719 and 1846 kg ha-1 seed cotton yield and seed yield respectively. It was 48 and 41 per cent and 51 and 47 per cent higher seed cotton and seed yield than recommended level in MCU 5 and TCHB 213 respectively. Under laboratory condition, the resultant seeds of variety and hybrid recorded significantly higher per cent germination, seedling growth measurements, drymatter production and vigour index with corresponding increase in fertilizer levels except in 200:0:200 NPK kg ha¹.
