Effects of light intensity and cocopeat amendments on the growth and yield of Kulai chili (Capsicum annuum L.udvar. Kulai)

摘要

Capsicum (capsicum annuum L. var. Kulai) is becoming increasingly popular as a spice and food colourant. The objectives of this study were to determine the effect ofuddifferent light intensity (50%, 70% and 100%) and different types of amended coco peat (coco peat only, coco peat with EM, cocopeat with biochar and cocopeat with EM and biochar) on the growth and yield of Kulai Chilli (Capsicum annuum L. var. Kulai).The experiment was carried out at School of Sustainable Agriculture, Universiti Malaysia Sabah, Sandakan Campus, Sandakan, Sabah, Malaysia. The study was a fieldudand laboratory study. A Random Complete Block Design (RCBD) was used with seven treatments replicated three times. Parameters were the leaf number, plant height (cm), fruit length (cm), number of matured fruits per plant, circumference of fruits (cm), wet weight of fruits (g), and dry weight of fruits (g). Probability test (Two-wayudAN OVA) was used to analyse the data collected at 0.05 Significant level. There were Significant effect of light intensity towards the growth, production and quality of Kulai Chilli. The growth of Kulai Chilli plant increased with the increase of light intensity. 100% light showed the highest mean for plant height (32.58 cm) and number of leafudper plant (31.00). The production of number of matured fruits per plant also showed the highest mean at 100% light intensity (2.92). The quality of fruits produced in termsudof length of fruits (12.21 cm), circumference of fruits (5.42 cm), wet weight of fruits (15.79 g), and dry weight of fruits (3.16 g) also showed the highest mean at 100%.udThere were also Significant effect of different types of amended cocopeat towards the growth, production and quality of Kulai Chilli. The best combination for amendedudcocopeat is cocopeat with EM and biochar which showed the highest mean for plant height (33.73 cm), number of leaf per plant (35.67), number of matured fruits per plant (2.22), length of fruits (10.34 cm), circumference of fruits (5.47 cm), wet weight of fruits (12.79 g), and dry weight of fruits (2.56 g). There was no significant interaction between light intensity and coco peat amendments towards plant height, number of leaf per plant and number of matured fruits per plant. There were significant interaction between light intensity and coco peat amendments towards theudlength of fruits, circumference of fruits, wet weight of fruits, and dry weight of fruits.
