Abstract

Four similar experiments were conducted at the Isabela Substation during 1972-73 to determine the effect of N, P2O5 and K2O on the yields and quality of head-cabbage variety Hybrid Head Start. The experiments were conducted during the four seasons of the year. Two planting distances were also studied. There was a tendency for maximum marketable yields with N applications of 0.2 units (224.2 kg/ha) to 0.4 units (448.4 kg/ha); 0.8 units of P2O5 (896.8 kg ha); and plant density of 71,700/ha. There was no measurable response to K applications. Variations in applied N, P, or K did not affect solidity (firmness) of the heads. Yield of marketable cabbage was somewhat higher in winter, but a reasonable production was obtained throughout the year in four experimental plantings.
