Performance of cotton as influenced by distance between hills and NPK levels [Philippines]

Bansilan, B.L.
Results showed insignificant influence of both distance between hills and NPK levels on the days to 50% emergence and days to 50% formation of cotton bolls. The main effect of distance between hills revealed significant advantage of planting at wide distance (40 cm) over that of narrow distance (25 cm) by ensuring higher percentage of germination. The application of 50-50-50 kg NPK/ha significantly delayed the days to 50% squaring, days to 50% flowering, days to 50% flossing. Interaction between distance between hills and NPK levels showed the least number of bolls per plant when plants remained unfertilized and planted at a close distance of 25 cm between hills while highest boll weight was obtained at wide planting of 40 cm between hills and fertilized at 50-50-50 kg NPK/ha.
