Abstract

Potassium is really needed by melon plants to increase the sweet taste of the fruit. The element potassium can improve the size and quality of fruit during the plant's generative period and can add a sweet taste to the fruit. Meanwhile, phosphorus functions in the process of forming plant flowers and fruit as well as increasing fruit production and ripening. The aims of the research were to study interaction between the concentration and time application of MKP fertilizer on the production and quality of melon (Cucumis melo L.) and the effect of concentration and time application of MKP fertilization on the production and quality of melon (Cucumis melo L.). This experiment used Randomized Complete Block Design, which consist 2 factors, first factor was concentration of MKP fertilizer. Second factor was time application of MKP fertilizer. Data obtained were analyzed with F test, and were continued with HSD at 5 percent when significant. Results showed that there is an interaction between the concentration of MKP fertilizer and the time of application of MKP fertilizer for melon production and quality on the parameters of fruit weight, fruit diameter and total soluble solids. Providing MKP fertilizer with a concentration of 9 g.l-1 and application time of MKP fertilizer 42 and 49 days after planting is a good combination for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total dissolved solids (13.73 °brix). Providing MKP fertilizer with a concentration of 9 g.l-1 is the best fertilizer concentration for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total soluble solids (13.73 °brix). MKP fertilizer application time of 42 and 49 HST is the best time for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total soluble solids (13.73 °brix).

Abstract

Oyster mushroom is a commodity that is in high demand in the community. Oyster mushroom production in Indonesia is decreasing year after year as wood sawdust, which is often used as a media for oyster mushrooms, becomes increasingly difficult to get. Bamboo has a nutrient content similar to wood sawdust; therefore, bamboo sawdust can be utilized as a media for growing oyster mushrooms. The aim of this research was to find the best mixture of bamboo and wood sawdust for the growth and yield of oyster mushrooms (Pleurotus ostreatus). This research was carried out from July to October 2023 at Lampung State Polytechnic. This study used a randomized block design with one factor that was repeated four times. The following treatments were used: C0 = 100% wood sawdust, C1 = 90% bamboo sawdust + 10% wood sawdust, L2 = 80% bamboo sawdust + 20% wood sawdust, C3 = 70% bamboo sawdust + 30% wood sawdust, C4 = 60% bamboo sawdust + 40% wood sawdust, and C5 = 50% bamboo sawdust + 50% wood sawdust. The collected data was analyzed using analysis of variance (ANOVA) and then evaluated with LSD test at the 5% level. The results of this research were that the treatment of C5 = 50% bamboo sawdust + 50% wood sawdust gave the best results on the parameter of the mycelium growth rate, the time of the fruit body initiation (FBI), the number of hoods, the diameter of the hood, the thickness of the hood, the harvest, the harvest weight per baglog, and the total harvesting per plot.

Abstract

This study aimed to evaluate the growth and yield response of kailan (Brassica oleraceae var. Albograba) to various plant spacings and growing media under a hydroponic NFT system. The experiment was conducted from September to November 2024 using a split-plot randomized block design with two factors: plant spacing (10 × 10 cm, 15 × 15 cm, and 20 × 20 cm) and growing media (cocopeat, rice husk charcoal, and rockwool), resulting in nine treatment combinations with three replications. Observed variables included plant height, number of leaves, leaf width, leaf length, fresh weight per plant, fresh weight per plot, and dry weight per plant. The results showed that plant spacing significantly affected plant height and fresh weight per plot, with the closest spacing (10 × 10 cm) yielding the highest biomass accumulation per plot. Growing media had a significant effect on all measured variables, where cocopeat consistently produced the highest values for plant height, leaf growth, fresh weight, and dry weight, followed by rice husk charcoal, while rockwool resulted in the lowest performance. No significant interaction was found between plant spacing and growing media. Overall, the study demonstrates that a spacing of 10 × 10 cm combined with cocopeat as the growing medium provides the most optimal growth and yield in hydroponic kailan cultivation.
