Effects of Different Types and Dosage of Green Mulch on Yield and Quality of Aloe vera L. on Coastal Sandy Soil

A complete content of chemical substance from Aloe vera leaf makes this plant has many functions such as the ingredient of functional food for health, cosmetics, and herbal medicines. This research was aimed to determine the yield and quality of Aloe vera L. on various types and rates of green mulch in coastal sandy soil. The research was conducted in coastal sandy soil of Poncosari Srandakan, Bantul, Yogyakarta and done in a Randomized Complete Block Design (RCBD) of two factors with three replications. The first factor was four types of green mulch (shrimp evergreen, cashew, acasia and gliricidia). The second factor was various rate of green mulch consisted of three levels rates of leave mulch (5.0, 10.0, and 15.0 tons ha-1). Soil without mulching was used as a control treatment. The variables observed were yield at the first harvest time and leaf content quality which includes water, protein, fat, carbohydrate, ash, fiber, and mineral (Ca, Fe and Zn). The results showed that there was interaction between types and rates of leave mulch in all variables observed. Gliricidia leaf mulch gave the best effect with optimum rate about of 10 ton ha-1. The effectiveness of green mulch abilities on improving the observed variables from higher order to low was gliricidia, acasia, cashew and shrimp-type evergreen with the rate range between 10 up to 15 tons ha-1

Variabel pengamatan meliputi komponen pertumbuhan dan hasil polong kedelai jepang. Analisis statistik dengan sidik ragam dan dilanjutkan dengan Duncan’s Multiple Range Test pada tingkat signifikan 5%. Kesimpulan: tidak terjadi interaksi antara pemberian dosis pupuk NPK dan mikoriza terhadap semua variabel pengamatan. Pemberian pupuk NPK dosis 150 kg per ha meningkatkan karakter agronomi dan indeks tanaman. Pemberian mikoriza dosis 150 kg per ha meningkatkan karakter agronomi bobot polong namun tidak meningkatkan indeks tanaman. Pemberian pupuk NPK dan mikoriza meningkatkan karakter agronomi dan indeks tanaman edamame dibandingkan dengan kontrol. Kata kunci: Bobot polong segar, efektivitas bintil akar, mikoriza

Potential Liquid Fertilizer Made from Goat Feces to Improve Vegetable Product

This study was carried out to examine the production of liquid fertilizer made from goat feces (LFGF) as well as the potency of LFGF for increasing plant growth and yield of vegetables. The study was conducted through 3 studies. The first study was begun with compiling a formulation for LFGF. The selected-raw-material was goat feces added with sugar and ZA, as well as EM (Lactobacillus sp., Actinomycetes sp., Streptomyces sp. and Yeast). The experimental results indicated that an increase in the concentration of ZA resulted in an increase in the total N and S content, as well as an increase EC of LFGF. Increased sugar concentration results in a decrease in pH and an increase in lactic acid content, whereas an increase in ZA decreases the formation of acetic acid. The use of sugar 25 g L−1 water and ZA 50 g L−1 water could produce the best quality of LFGF. The second study was to examine the selected LFGF combined with AB-Mix nutrient solution on the growth and yield of three types of leaf vegetables which were cultivated hydroponically. The results indicated that LFGF can potentially replace AB-Mix fertilizer by up to 50% in hydroponic vegetable cultivation. The third study was to examine the selected LFGF as nutrients availability of mustard that was cultivated in pots, given through planting media with a concentration of 1:40 L−1 water (EC 2300 μS cm−1). It shows that LFGF has the potential to increase the growth and yield of mustard plants in pots
