Abstract

This study aims to evaluate the effects of crop rotation on soil quality and water use efficiency in Gunungsitoli. The method used was a Randomized Complete Block Design (RCBD) with treatments consisting of monoculture and crop rotation systems. Data were collected from soil pH analysis, organic matter content, nutrient levels (N, P, K), and measurements of water use efficiency during the growth period. The results indicated that crop rotation significantly improved soil pH, organic matter content, and water use efficiency compared to the monoculture system. The implementation of crop rotation proved effective in enhancing soil quality and supporting sustainable agricultural practices. This study recommends crop rotation as a strategy to boost agricultural productivity and preserve natural resources.

Abstract

Response of kangkung (Ipomoea aquatica Forsk.) to irrigation with rice washing water over a 24-hour period in Gunungsitoli. Sustainable agriculture increasingly emphasizes the use of natural resources, and rice washing water is known to contain essential nutrients for plants. The research aims to identify early physical changes in plant height and leaf count, as well as the visual condition of kangkung after the application of rice washing water. The method used was a controlled experiment with two groups: control (irrigated with plain water) and treatment (irrigated with rice washing water), each with replications. Plant height measurements and leaf counts were taken at the start and after 24 hours of treatment, accompanied by visual observations. Results indicated a slight average increase in plant height for the treatment group (0.2 cm) compared to the control (0.1 cm) within 24 hours. However, no significant change in leaf count was observed for both groups. Visually, plants treated with rice washing water appeared slightly brighter. While this response is minimal, the study suggests the potential of rice washing water as an early growth stimulant and highlights the importance of longer observation durations for a comprehensive understanding of its nutritional impact.

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.
