Abstract

Yard-long bean (Vigna unguiculata L.) is an important horticultural commodity that requires optimal nutrition for maximum growth and production. This study aimed to determine the optimal dose of compost fertilizer that can improve the yield and quality of yard-long bean plants. The research was conducted using a Completely Randomized Design (CRD) with 5 compost fertilizer dose treatments: K0 (control), K1 (10 tons/ha), K2 (20 tons/ha), K3 (30 tons/ha), and K4 (40 tons/ha), each replicated 4 times. The observed parameters included plant height, number of leaves, pod length, number of pods per plant, pod weight per plant, and chlorophyll content. The results showed that compost fertilizer application significantly affected all growth and production parameters. Treatment K3 (30 tons/ha) gave the best results with an average plant height of 185.5 cm, 42.3 pods per plant, and pod weight of 245.7 g per plant. The highest chlorophyll content was also obtained in K3 treatment with a value of 48.2 SPAD. Application of compost fertilizer at a dose of 30 tons/ha is the optimal dose for improving the yield and quality of yard-long bean plants, with a production increase of 67.3% compared to the control.

Abstract

This study aimed to analyze the effect of shading on the growth and photosynthetic rate of red chili pepper (Capsicum annuum L.). The results showed that shading treatment had a significant effect on morphological parameters, namely plant height and total dry weight, but did not significantly affect leaf width, leaf number, and leaf length compared to plants grown without shading. Physiologically, shading influenced quantum yield, photochemical quenching, and non-photochemical quenching, whereas the maximum photosynthetic rate (Pmax) did not show a significant difference. From an ecophysiological perspective, shading treatment significantly increased proline and ascorbic acid contents. These findings indicate that red chili pepper exhibits a high adaptive capacity to low light intensity conditions. This study is expected to contribute as a reference material and learning resource in the fields of plant physiology and plant biology.
