Abstract

The aimed of this study was to determine the effect of chicken manure application on red chili plants using conventional and floating cultivation techniques. The research was carried out on the experimental farm for conventional cultivation techniques and in research pond for floating cultivation located in the Faculty of Agriculture, Sriwijaya University, Indralaya Campus, Ogan Ilir, South Sumatra with an altitude of 10 m above sea level from July to November 2022. The experiment used a randomized block design with one factor, namely chicken manure (0, 10, 20 and 30 tons/ha) with three replications. While the floating experiment used 200 cm x 100 cm of bamboo rafts. Parameters observed included plant height, number of leaves, crown diameter, fruit length, fruit diameter, fruit weight per fruit, and total fruit weight per plant. Data were analyzed using Analysis of Variance (ANOVA) at the 5% level. The results showed that increasing the dose of chicken manure up to 30 tons/ha in both cultivation techniques increased plant height and number of leaves. Likewise for the number and weight of fruit, obtained at the same dose in conventional techniques, namely 30 tons/ha. However, fruit length and diameter parameters were higher in floating cultivation at all doses of chicken manure treatments. Therefore, it was concluded that the use of chicken manure could increase the growth of chili plants in both cultivation techniques, although the size of the polybags used could not support the growth and yields optimally.

Abstract

Chaya leaves (Cnidoscolus aconitifolius (Mill.) I.M. Johnst.) are leafy vegetables that contain many vitamins and minerals. Information about the intensification of chaya cultivation is still rare. Chaya propagated by stem cuttings. The maturity level of stem cuttings and planting media were expected to affect the success of plant propagation. This study aims to determine the maturity level of cuttings material that can grow well and deter-mine the type of media that can support the growth of chaya propagation. This research has been carried out from July to October 2022 in an off-campus experimental outdoor facility located in Inderalaya, South Suma-tra. This study was conducted using a randomized block design with 2 factors. The first factor was the level of maturity of stem cuttings material (upper, middle, and basal), and the second factor was the type of growing medium (control, chicken manure, and cow manure). The results showed that the use of cuttings from the mid-dle and basal has a better percentage of growth ability than the upper cuttings. Chaya plants used basal stem cuttings exhibited slower shoot grow but produced higher number of leaves, greater leaf area, canopy area, and biomass. The use of cow manure in a mixture of growing medium gave the best results on growth of chaya plants.

Abstract

[GROWTH AND HARVESTING FREQUENCY OF RED CHILI PLANTS WITH THE APPLICATION OF  NPK FERTILIZERS CULTIVATED ON SUB-OPTIMAL LAND IN FLOATING CULTURE SYSTEM]. The low productivity of red chili in South Sumatra is mostly due to its cultivation was conducted in sub-optimal land that is less favorable for producing vegetable crops. This study aimed to evaluate growth and yield of red chili plants under suboptimal conditions using various doses of NPK fertilizer. The experiment was carried out from June to October 2022, at the water reservoir and experimental field (as a comparison) at the Faculty of Agriculture Universitas Sriwijaya, Indralaya, South Sumatra with an altitude of 10 m above sea level. Both experiments were arranged in a randomized block design with three replications and one factor in the group, namely NPK fertilizer doses (0, 5, 10, and 15 g/polybag). For the experiment in the water reservoir, each treatment was arranged randomly in a 200 cm x 100 cm bamboo raft (for each group). The results showed that the application of NPK fertilizer in floating cultivation did not increase plant height, number of leaves, shoot diameter, and harvesting frequency of red chili. It was concluded that the application of NPK fertilizer in floating cultivation did not increase growth and harvesting frequency of red chili.
