Abstract

Utilization Compost of Durian Shell to Reduce Dose of N Inorganic Fertilizer in Green Cabbage (Brassica junceae) Production. The high public demand for organic products are not comparable with the level of production. One of alternative producing agricultural healthy products is using agricultural waste as organic fertilizer for crop production. Durian shell can be used as an alternative material to make organic fertilizer. The study said that the durian shell can be used into useful organic fertilizer for plants and improving soil chemical properties. Based on this potential, research on the use of organic fertilizer from shell of durian need to performed. The results indicate that the solid organic fertilizer durian shell contains 14.6% C- organic, 1.69% N, 0.16% P2O5, and 1:20% K2O. The research aims to determine the effect of organic fertilizer from shell of durian and test their effectiveness in reducing the dose of inorganic N fertilizer on growth and yield of green cabbage (Brassica junceae). This research was conducted with randomized complete block design at the Experimental Garden Trilogy University, Jakarta. Research in the field include the dosage of organic fertilizer (0, 10, and 20 t / ha) and inorganic N fertilizer (0%, 50%, 75% and 100% of the dose recommendation of 250 kg / ha). The results showed no differences plant growth in all treatments. Fresh wet of shoot in the treatment of 20 tons of organic fertilizer + 50% inorganic fertilizer dose did not differ significantly by treatment with 20 tons of inorganic fertilizer + 100% inorganic fertilizers. This result conclused the application of organic fertilizer durian shell is able to reduce the dosage of inorganic fertilizer up to 50%.

Abstract

Efforts to Increase Production and Quality of “Kristal” Guava Variety (Psidium guajava L. cv. Kristal) by Fertilization. Nowadays “Kristal” guava variety (Psidium Guajava L. cv. Kristal) is very popular for consumers because it has several advantages such as flesh fruit is crunchy, sweet-sour taste with slightly seeds or seedless, and shelf life of fruit relatively long that can be up to 1 month if stored at temperature of 10-15 oC. The challenge faced by farmers are the production and fruit quality still low, due to inadequate maintenance done. This research was conducted to study the effect of fertilizer to increase the production and quality of “Kristal” guava variety. Research was carried out in farmers garden at Pelaga Village, District of Petang, Badung Regency, Bali, from April-November 2016. The study was a randomized block design (RBD) with fertilizer treatment consisted of 4 levels and each repeated 6 times. The results showed that fertilization increase production and quality of “Kristal” guava fruit compared to the control. The highest weight of fruit per plant (18.28 kg / plant) were obtained on plants fertilized with compost 5kg/plant + urea 200 g/plant + KCl 250 g/plant + TSP 250 g/plant + gypsum 500 g/plant+ micro fertilizer CuSO4 and ZnSO4 1.5 g/plant, respectively, given once at the beginning of the study and significantly different compared to the lowest weight of fruit per plant which obtained on controls (8.99 kg/plant). The highest fruit diameter (8.72 cm) obtained on plants fertilized with compost 5kg/plant + urea 200 g/plant + KCl 250 g /plant + TSP 250 g / plant + gypsum 500 g/plant + micro fertilizer CuSO4 and ZnSO4 each 1.5 g/plant, respectively, given three times i.e at the beginning of the study, at the phase of anthesis, and at the maturity of fruit and significantly different compared to control (7,50 cm).
