Abstract

Cucumber (Cucumis sativus L.) is rich in nutrients and vitamins, an is popular for fresh salads and various processed foods. The objective of this work is to study the effects of branch pruning and NPK fertilizer dose on the growth and yield of baby cucumber in order to solve the decrease in cucumber production. The research was executed in Dander Village, Bojonegoro Regency, East Java. The experiment was performed according to a Randomized Block Design with two factors. The first factor is branch pruning, and the second factor is the dose of NPK fertilizer. Branch pruning was carried out in four ways: no pruning, pruning branches at nodes 1–3, nodes 1–4, and nodes 1–5. The NPK fertilizer dose was also applied at four levels: 800, 900, 1,000, and 1,100 kg/ha. The observed parameters included plant length, number of leaves, time to female flower appearance, fruit length, number of fruits per plant, total fruit weight per plant, and fruit weight per hectare. The data were analyzed using analysis of variance (ANOVA) and tested with HSD at 5%. The results showed that the combination of no pruning and the application of 1,100 kg/ha NPK fertilizer produced the best results in terms of fruit weight per hectare.   Keywords: Baby cucumber, Branch pruning, Harvest, Macro-nutrients, Photosynthate translocation.

Abstract

Cayenne pepper cultivation in urban areas faces several obstacles, including infertile soil, irregular watering due to busy daily activities, pests and diseases that spread more easily in urban areas, and high temperature changes. This study aims to obtain the optimal concentration of paclobutrazol and Gandasil fertilizer for the development and production of cayenne pepper. This study used a factorial completely randomized design with two factors, namely paclobutrazol concentration consisting of 4 levels (0 ppm, 75 ppm, 100 ppm, and 125 ppm) and Gandasil B/D fertilizer consisting of 4 levels (1 g/L, 2 g/L, 3 g/L, and 4 g/L). Results showed that treatment combination of paclobutrazol 100 ppm and Gandasil 3 g/L gave the best results on the number of flowers per plant (822.0), number of fruits per plant (144.5), and fruit weight (156.77 g/plant). This combination may, however, result in low fruit yield and inhibit vegetative development, including leaf number and plant height. The fastest flowering age was obtained at combination paclobutrazol 125 ppm and Gandasil concentrations of 4 g/L with a value of 39.33 days.   Keywords: Concentration, Gandasil fertilizer, Growth, Paclobutrazol, Yield.

Abstract

The demand for avocados in Indonesia continues to rise, while the availability of high-quality seedlings remains limited. Propagation through stem cuttings with the application of IBA (Indole Butyric Acid) is expected to improve propagation success. This study aims to determine the effect of IBA concentration on the growth of avocado stem cuttings. The research was conducted in Bojonegoro, East Java, using a Completely Randomized Design (CRD) with one factor, namely five concentrations of IBA: 0, 75, 100, 125, and 150 ppm. Observed parameters included shoot length, number of shoots, number of leaves, and number of primary roots. The results showed that IBA concentration had a significant effect on all observed parameters, while cutting length had no significant effect. A concentration of 100 ppm produced optimal growth of 1.92 cm, 2.50 shoots, and 4.33 leaves. The treatment without IBA resulted in the lowest values. The application of IBA at concentrations of 75–100 ppm effectively enhanced the growth of avocado stem cuttings, particularly in shoot and leaf development.
