Abstract

Strawberries are a fruit commodity that has high economic value. The obstacle in strawberry production is the lack of high-quality seed availability with disease-free properties. Tissue culture offers a promising solution to increase both the quantity and quality of strawberry seeds. This study aims to assess the effect of different concentrations of tomato juice and tryptone on the growth of strawberry explants under in vitro growing condition. The research was conducted at the Plant Breeding Laboratory, Faculty of Agriculture, Universitas Jenderal Soedirman, from December 2022 to May 2023. The study employed a Completely Randomized Design (CRD) with two factors. The first factor was tomato juice (Z), consisting of Z0 = 0 mL/L, Z1 = 50 mL/L, Z2 = 100 mL/L. The second factor was tryptone (T), consisting of T0 = 0 g/L, T1 = 1 g/L, T2 = 2 g/L, T3 = 3 g/L. The addition of 50 mL/L tomato juice solely (T0Z1) resulted in the highest plant height, number of leaves, number of branches, and leaf width. Meanwhile, the addition of2 g/L tryptone solely showed the highest germination rate.

Abstract

Melon is one of the horticultural commodities with considerable economic potential. Cultivation through hydroponic systems can provide efficiency and increase production if complemented by superior varieties. This study aims to identify the best hydroponic system and melon variety combination with the highest yield. The research was conducted from November 2023 to April 2024 at the screen house in Pasir Kulon Village, Karanglewas District, Banyumas Regency, at 110 m above sea level. The study used a split-plot factorial design with a basic design of a Completely Randomized Block Design. The first factor was the hydroponic system, consisting of S1 = Dutch bucket and S2 = drip irrigation. The second factor was the variety, consisting of V1 = Golden Aroma, V2 = Rangipo, and V3 = Sweet Net. The results showed that the best yield was found in the Dutch bucket system and the Golden Aroma variety, with a fruit flesh thickness of 3.3 cm and a total soluble solids content of 17.18 °Brix.

Abstract

Rabbit urine liquid organic fertilizer (LOF) can be used as an alternative fertilizer to reduce the use of inorganic fertilizers, especially for shallots, as a national food commodity. This study aims to determine the best concentration of rabbit urine LOF, the best dose of NPK fertilizer dose reduction, and a combination of rabbit urine LOF and NPK fertilizer dose reduction on the physiological characters of shallot plants. The observed variables consisted of net assimilation rate, crop growth rate, stomatal density, stomatal aperture, and chlorophyll content. The experimental results showed that a concentration of 200 mL L-1 of rabbit urine LOF had the best effect on several physiological characteristics studied. In addition, a 50% reduction in the NPK dose had the best effect on physiological characteristics compared to other treatments. Rabbit urine LOF 200 mL L-1 and a 50% reduction in NPK doses had a significant interaction effect on the physiological characters of shallot plants.
