Abstract

Yellow sap contamination is one of the constraints in producing export quality of mangosteen. The contamination can be reduced by strengthening cell walls with an application of Ca during the fruit growth stage. This study aimed to explore dosages and application times of dolomite (CaMg(CO3)2) and their effects on yellow sap contamination. The experimental design was a Randomized Block Design with two factors and the factors were arranged factorially with three replications. The first factor was dosage of dolomite (D) that consisted of 0 g/tree, 3000 g/tree, and 9000 g/tree, and the second factor was time of dolomite application that consisted of 2 weeks after anthesis (WAA) and 6 WAA. The results showed that the application of dolomite at 3000 g/tree and 9000 g/tree reduced the percentage of yellow sap contamination in fruit by 23,07% and 24,20%, repectively as compared to no dolomite application treatment. Meanwhile, time of application did not affect yellow sap contamination in fruit. It is suggested to apply 3000 g/tree of dolomite at the fruit growth stage to reduce yellow sap contamination in mangosteen fruit.

Abstract

This study aims to determine the effect of several low light intensities on the growth and yield of F7 generation vegetable beans. This research was conducted in October 2019 to January 2020. The method used was experimental with an experiment in the Agarwood Glasshouse of the Faculty of Agriculture, University of Mataram. The experimental design used was a Completely Randomized Design (CRD) with 4 treatments and was repeated 5 times so that 20 experimental units were obtained. Data were analyzed by analysis of diversity at the 5% level. If there is a significantly different treatment (P <0.05) then the follow-up test with the Duncan's Multiple Range Test (DMRT) at 5%. The treatment given is the effect of low light intensity consisting of N0 = 100% light intensity (without shade), N1 = 45% light intensity (55% shade), N2 = 35% light intensity (65% shade), and N3 = intensity light 15% (shade 85%). The results showed that low light intensity had an effect on reducing the weight of seeds per plant, but at low light intensity 35% and 15% were not significantly different, but lower than the low light intensity of 45%. At low light intensity 15% decreases the pod weight per plant, but does not decrease at low light intensity 45% and 15%. In addition, low light intensity results in fewer leaves and branches compared to without shade, but increases leaf area and plant length.
