A study to identify an appropriate dose of nitrogen and phosphorus for late season
cauliflower (May production) was accomplished in the upper mid hills of eastem Nepal.
The experiment was conducted during the two consecutive years of 2000 and 2001. Three
level of nitrogen (60, 100 and 140 kg/ha) and the same level ofphosphoms (40, 80 and 120
kglha) were tested to Kibo Giant variety mailllaining a plant spacing of 45x30 em between
and within rows. Application of a minimum level (60:40:50 N: P20 5: K20 kg/Ita) of mineral
fertiliur yielded about a double ( 12.02 t/ha) curd yield titan that of only using compost at a
rate of 30 t/ha (6.77 t/ha). Among the different combinations of Nand P205fertilizers, only
different doses of nitrogen played role on curd yield. Analysis of variance of nitrogen,
phosphorus and their illferaction showed a significant (p<. 001) effect of nitrogen and nonsignificant
effect of different levels ofphosplwrus and their interactions. Nitrogen 140 kg/ha
yielded statistically the highest ( 19.65 t/ha) curd yield, which was followed by 100 kg
nitrogen per hectare ( 16.79 t/ha). There was a positive trend of increased level of nitrogen
(y=10.96+2.9x) belt not a clear trend of phosphorus. Pre and post experiment soil and plant
analysis failed to show significant correlation among N, P20s. K20, pH and OM contellts.
The results have given new direction in relation with fertilizer management for late season
cauliflower cultivation in the upper mid hills of east em Nepal.
