Standardization of fertilizers and its effect on growth and yield of cauliflower (Brassica oleracea) under Bamyan condition

Abstract

The current study was conducted on the effect of different dose of NP fertilizer on cauliflower in Fuladi valley of Bamyan during the year 2017. The objective of the study was to know the optimum dose of fertilizer, namely NP in cauliflower. The experiment had three levels of NP fertilizer T2 (50%), T3 (75%), T4 (100%) and T1 (zero NP) based on recommended dose of NP. The result showed that the highest plant height (45.66 cm) was observed at T2 (50% NP) followed by (44.33 cm) at T4 (100% NP) and the lowest plant height was (36.33 cm) recorded at T1 (control treatment), maximum plant spread (68.66 cm) was recorded at T4 (100% NP) fertilizer followed by (66.66 cm) at T2 (50% NP) recommended fertilizer dose and minimum plant spread (58.33 cm) was recorded at T1 (control treatment) and the observation which was recorded at 20th July the maximum No. of leaves/plant (19.33 leave/plant) were observed at T3 (75% NP) followed by (18 leave/plant) with T2 (50% NP) and (16 leave/plant) with T4 (100% NP) application, while the minimum number of leaves/plant was obtained (15.66 leave/plant) at T1 (control treatment).The highest yield (46.2 m ton/ha) was recorded at T4 (100% NP) followed by (44.2 m ton/ha) at T3 (75% NP) and lowest yield (28.6 m ton/ha) obtained in control treatment. This might be due to nutrient availability by applying different level of chemical fertilizer. The study concluded that application of 100% of NP might be useful under Bamyan condition.
