Abstract

This research aims to determine the best dose of KCl fertilizer and humic acid for peanut yields. The study was conducted using a split-plot design with two factors, and each factor was repeated three times. The dose of KCl as a subplot consisted of 4 levels (0, 50, 75, and 100 kg/ha), while humic acid as the main plot consisted of 4 levels (0, 10, 20, and 30 kg/ha). Observation included the number of non-productive gynophores, the number of pods, dry weight harvest yield (pods per plant, pods per plot, seeds per plant, and seeds per plot), and the weight of 100 seeds. The single factor of KCl dosage significantly affected the dry weight of pods per plant, dry weight of seeds per plant, and dry weight of seeds per plot. The single factor of humic acid treatment had no significant effect on all observation variables, while the interaction of KCl and humic acid doses significantly affected the number of non productive gynophores and the weight of 100 seeds. The best dosage was 100 kg/ha, producing the highest yield with a dry seed weight per plot of 147.43 g. The combination of KCl 75 kg/ha and humic acid 30 kg/ha produced peanuts with the best quality, with weight 100 seeds of 39.47 g. Keywords: Humic acid, KCl, Peanut, Potassium, Yield.

Abstract

Melon (Cucumis melo L.) is a fruit known for its sweet and refreshing taste. Traditionally, melon cultivation has relied on conventional farming methods. The use of biofertilizers offers an alternative to reduce dependency on synthetic fertilizers. This study aimed to enhance the production of healthy, high-yielding melon plants by substituting Mutiara NPK fertilizer with Bioto Grow Gold (BGG) biofertilizer. Conducted in Sukosongo Village, Kembangbau District, Lamongan Regency, East Java, the experiment employed a factorial Completely Randomized Design (CRD).Two factors were tested: BGG fertilizer at four concentrations (0 ml/L [P0], 1 ml/L [P1], 2 ml/L [P2], and 4 ml/L [P3]) and NPK fertilizer at four doses (0 g/plant [N0], 60 g/plant [N1], 70 g/plant [N2], and 80 g/plant [N3]). Results indicated that BGG fertilizer influenced both vegetative and generative growth variables, as did the Mutiara NPK fertilizer doses. The optimal combination was achieved with a BGG concentration of 3 ml/L and an NPK dose of 70 g/plant, which significantly increased the sucrose content in melons. Keywords: Bioto Grow Gold fertilizer, Biofertilizer, Melon, NPK Mutiara fertilizer.

Abstract

Fig cuttings often face problems with failure of the roots to grow from the cuttings, so efforts are needed to encourage root induction by administering auxin growth regulators. Rootone F is an exogenous PGR from the auxin group which can stimulate root growth. In order for the roots to grow, develop and function well, plants need an ideal planting medium. The ideal planting medium to support good growth of plant seeds is a proportional composition of physical, chemical and biological elements. The aim of the research was to examine the combined effect of Rootone F concentration and planting media composition on the vegetative growth of fig cuttings. The research consisted of two treatment factors, namely the concentration of Rootone F (0 ppm (Control), 100 ppm, 150 ppm and 200 ppm) and the composition of the planting media (soil: husk charcoal: cow manure) with a ratio (1:1:1), (2:1:1), and (3:1:1). The best treatment combination is 150 ppm Rootone F and planting media mixed with soil: roasted husks: organic cow fertilizer with a ratio of 3:1:1 which has a significant effect on shoot length, root length, fresh weight of roots and percentage of live cuttings (%). A concentration of 100 ppm Rootone F gave the best results when the first shoots appeared (DAT), a concentration of 150 ppm Rootone F gave the best results on the number of leaves. A planting medium composition of (3:1:1) gives the best results when the first shoots appear (DAT).   Keywords: Auxin, Growth regulator, Influence, Nutrient, Vegetative.
