Abstract

Bean plants are one of the groups of legumes that are popular with the public. In addition, beans are one of the sources of vegetable protein, vitamins A, B, and C found in their seeds. The demand for beans is increasing every year. Fertilization is an effort to increase the harvest of a plant cultivation. The use of organic fertilizers, both liquid and solid, can be a solution to reduce excessive application of inorganic fertilizers, because organic fertilizers can improve the physical, chemical, and biological properties of the soil. The purpose of this study was to determine the effect of giving Guano fertilizer and SP-36 fertilizer doses on the growth and yield of bean plants. This study used a Factorial Randomized Block Design with 2 factors: Factor l, namely Guano fertilizer (G) with 4 levels, namely: G0 = 0 g/plant (Control), G1 = 30 g/plant, G2 = 60 g/plant and G3 = 90 g/plant. Factor 2, namely the provision of SP36 (K) fertilizer with 4 levels, namely: K0 = Control (0 g/plant), K1 = 1.5 g/plant, K2 = 3 g/plant, K3 = 4.5 g/plant. The parameters observed in this study include plant height, number of branches, number of pods/plant and weight of pods/plant. The results of the study showed that the provision of Guano fertilizer had no significant effect on plant height, number of primary branches, number of pods and weight of pods. Guano fertilizer is a biological fertilizer that is given to add organic material to bean plants

Abstract

Sweet corn plants have good prospects for cultivation, because they have a higher selling price than ordinary corn and have a relatively short production life. To meet the increasing demand, farmers need to make efforts to improve good cultivation systems. Among them are empowering the use of organic materials. The purpose of the study was to determine the response of CMA fertilizer and varieties to sweet corn plant production. This study was conducted at the UNIVA agricultural land on Jalan Simalingkar B Medan. This study was conducted from April to July 2024. This study used a factorial randomized block design consisting of two factors, namely: Factor 1, CMA fertilizer consists of 45 levels, namely: C0 = control, C1 = Liquid fertilizer dose 5 ml / liter, W2 = Liquid fertilizer dose 10 ml / liter, W3 = Liquid fertilizer dose 15 ml / liter, W4 = CMA fertilizer dose 30 gr / plant, C2 = CMA dose 60 gr / plant, and C3 = CMA dose 60 gr / plant. Factor 2The second factor is the variety consisting of 4 levels, namely: V1 = Secada, V2 = Panglima, V3 = Sweet boy, V4 = Bonanza F1. The results of the study showed that the use of CMA fertilizer was significantly different from the gross weight of production per sample and the net weight of production per sample. The best treatment was C3 with a dose of 90 grams / plant. The use of varieties was significantly different from the gross weight of production per sample and the net weight of production per sample, the best variety was V4, namely the Bonanza F1 variety.Keywords: Sweet Corn, biofertilizer, Varieties

Abstract

Naphthaleneacetic acid (NAA) and kinetin play a crucial role in plant growth but must be used in correct proportions in order to produce the best outcomes. An optimal combination of both can enhance shoot, leaf, and root growth, whereas inappropriate doses may otherwise inhibit growth due to hormonal imbalance. This study examined the effects of the interaction between NAA and kinetin on the growth of chrysanthemum plants at eight weeks of age. The research was carried out using the Completely Randomized Design (CRD) in triplicate. The medium used was MS medium, supplemented with NAA at concentrations of 0–1.5 mg/L and kinetin at concentrations of 0–3 mg/L. The results indicate that NAA and kinetin positively influenced plant growth, but only when the optimal concentrations were applied. The best combination of NAA at 1.0 mg/L (N2) and kinetin at 3.0 mg/L (K3) produced the best results in terms of height (153 mm), number of leaves (31 leaves), number of roots (26 roots), and fresh weight (5.85 g). Increasing kinetin concentrations (K0-3) generally promoted plant growth, whereas excessive NAA concentrations (> 1.0 mg/L, N3) produced the opposite effect, likely due to toxicity or hormonal imbalance. The interaction between kinetin and NAA exhibited a synergistic effect up to a certain threshold, while excessive NAA application negatively impacted on plant development.
