Abstract:
Fertilizer rate of NPK blue was tested for chilli planting. The experiment was carried out at Green House, Universiti Malaysia Terengganu (UMT). This study was conducted to evaluate the effect of NPK blue on growth, flowering, fruiting and quality of chilli (Capsicum annum L.) grown on bris soil. Nitrophoska Blue Special 12: 12: 17 :2 have definite composition and major fertilizing nutrients such as nitrogen,
phosphorus and potassium. There are four treatments which were used in this project. The result of the study indicated that fertilizer rate of NPK blue had no influence the
plant diameter. The application of high rate of NPK blue have resulted in even better plant's height in treatment 4 than other treatments especially after 8 th weeks of
planting. The application of high rate of 800 kg/ha NPK blue (treatment 4) have resulted the high number of leaf than other treatments after 6 th weeks of planting. On
the 3rd week of planting, the plant of treatment 3 give higher number of flowers, followed by treatment 1, treatment 4 and lastly treatment 2. On the 4th weeks of
planting, plant in treatment 3 give higher numbers of fruits followed by treatment 1, treatment 4 and treatment 2. Overall, fruit in treatment 4 had higher pH, followed by
treatment 3, treatment 2 and treatment 1. Besides, fruit in treatment 4 also noticed that higher soluble sugar concentration followed by treatment 3, treatment 2 and treatment 1. Fruit diameter in treatment 3 noticed that higher fruit diameter followed by treatment 4, treatment 2 and treatment 1. The plant in treatment 4 showed better fruit length followed by treatment 3, treatment 2 and treatment 1. Generally, based on the parameter such as number of leaf, height of plant, number of fruit, and number of flower , the application of 800 kg/ha of NPK blue and 600 kg/ha of NPK blue gave best results to the treatments.
