Abstract

his research was conducted in a plastic house at the Lampung State Polytechnic from June to October 2022. The study was a factorial experiment consisting of two factors with a randomized block design. The first factor is the type of planting media with 4 kinds, such as cocopeat, husk charcoal, sand, and soil. The second factor is the polybag size, such as small, medium, and large sizes. Each factor or treatment was repeated 3 times. The tools and materials used are drip irrigation, digital scales, polybags, pearl NPK fertilizer and caisim seeds. The objectives of the study were (1) to measure the growth and production of caisim plants on various planting media and polybag sizes, (2) to measure the amount of irrigation water used, and (3) to calculate the water productivity of caisim plants. The observed variables included crop production, amount of water use, and water productivity. Data analysis using ANOVA at the 5% significant difference test level. The results showed that there was no interaction between the type of planting media and the size of polybags, but the response in the treatment between types of planting media and between polybag sizes was significantly different. The type of media significantly affected the number of leaves, plant height, production, and water productivity of hydroponic caisim plants using a drip irrigation system. Polybag size did not significantly affect the number of leaves, plant height, production, and water productivity of hydroponic caisim plants using a drip irrigation system. In hydroponic caisim cultivation using drip irrigation, cocopeat growing media gave an average number of 9.8 leaves, plant height 34.4 cm, production 97.1 g, and water productivity 6.18 kg/m3 and was not significantly different from soil medium.

Abstract

Deficit irrigation is the application of water to crops in amounts lower than their full water requirement without causing a significant reduction in yield. This study was conducted to investigate the effect of deficit irrigation on Sultan melon plants using a randomized block design with four levels of deficit irrigation applied from planting to harvest: 0% deficit irrigation (control), 15%, 30%, and 45%. Each treatment was replicated three times, with each replication consisting of three experimental units. The results showed that deficit irrigation had no significant effect on the number of leaves and plant height of Sultan melon, but it significantly affected leaf area, fresh stem weight, and fruit weight. The average fruit weight of Sultan melon under 0% deficit irrigation was 0.785 kg per plant, which was not significantly different from 15% deficit irrigation at 0.680 kg per plant. The deficit irrigation level that provided optimal yield and water productivity for Sultan melon was 15%, with fruit weight and water productivity of 0.704 kg per plant and 15 kg per m³ of water, respectively.
