Abstract

The use of compost added by Trichoderma is one of improving the soil's chemical properties and can be used to increase the production of pakcoy plants. The purpose of this study was to determine the effectiveness of compost derived from various types of palm oil waste and the application of Trichoderma on soil chemical properties as well as production and nitrogen content in pakcoy plants. This study used an experimental method with parameters observing plant fresh weight. The research used two factors. The first factor was three types of palm oil waste, midrib leaf, oil palm empty bunches, and solid decanter. The second factor was the dose of Trichoderma, 50 ml, 100 ml, and 150 ml per plant. Planting media derived from solid decanter was able to intensification the production of pakcoy compared to midrib leaf and oil palm empty bunches.

Abstract

Hydroponic crop cultivation generally uses AB mix nutrient. However, the expensive price of AB Mix nutrient caused increasing production costs. In addition to the expensive price, the availability of AB Mix is also limited. As an alternative, there is a need for more affordable fertilizer such as compound fertilizer and foliar fertilizer. The purpose of this study was to (1) determine the best compound fertilizer concentration to growth and yield of Pakcoy; (2) determine the best foliar fertilizer concentration to growth and yield of Pakcoy; (3) determine the interaction between compound and foliar fertilizer to growth and yield of Pakcoy. This study was used Split Plot Randomized Block Design consist 2 replicated. Main plot was compound fertilizer concentration and sub plot was foliar fertilizer concentration.The resulted of this study was (1) 2.5 g/L compound fertilizer concentration provide the best growth and yield of Pakcoy; (2) there was no significant effect of foliar fertilizer concentration; (3) there was no interaction between tho treatnments.

Abstract

Stem cutting propagation is commonly used to vegetative propagated of Aglaonema sp, however the growing roots has not been much growth. Nevertheless, the shoots that grow only one to three buds with the length of time shoots and roots appear is about 50-75 days after cuttings. It is all depends on the genotype of the Aglaonema sp. The aims of this study was to (i) determine the effect of IBA and NAA concentration in inducing roots of Aglaonema sp. Var Siam Aurora stem cuttings; (ii) to determine the interaction of IBA and NAA treatments to inducing roots of Aglaonema sp. Var Siam Aurora; (iii) determine the best combination of IBA and NAA to inducing roots of Aglaonema sp. Var Siam Aurora. The experimental design was Randomized Block Design (RBD) Factorial with the first factor is the IBA concentration; 0 mg.l-1(I0) and 1000 mg.l-1(I1). The second factor is NAA concentration; 0 mg.l-1(N0), 500 mg.l-1 (N1), 1000 mg.l-1 (N2), 1.500 mg.l-1 (N3)and 2000 mg.l-1 (N4) and resulting 10 combination treatments of IBA and NAA. The data was conducted with analysis of variance and followed by BNT test at 5% and the variable observed were root length, number of roots, first time of roots growth, first time of buds growth, the percentage of cutting stem. The result showed that the combination of IBA and NAA 1000 mg.l-1 give significant effect to inducing cutting stem of Aglaonema sp. Var Siam Aurora.

Abstract

Organic chili cultivation has become a necessity nowadays as awareness increases about the dangers of chemical residues used in conventional cultivation practices. Chili is one of three main of vegetables commodities in Lampung. However, pepper yellow leaf curl disease is still a major obstacle faced by farmers to increase chili productivity. Therefore, the aim of this research is to study the characteristics of symptoms and the incidence rate of pepper yellow leaf cull disease of Capsicum annuum L. and Capsicum frutescens in organic cultivation practice. The results shown that the characteristics or early symptoms of pepper yellow leaf curl disease on chilies are yellowing of young leaves, mosaic and malformation which are found in C. annuum L and C. frutescens. The intensity of disease attacks on chili plants by giving POC from the Mimosa pudica roots (PM) gave positive efect with an average low attack intensity in the 8th week, namely 32% compared to giving POC from bamboo roots (AB) with an average attack intensity 45.5%. This indicates that POC from the roots of Mimosa pudica (PM) is capable of being a bioprotectant for chili plants. The application of POC type 3 also provided a positive response with a low intensity of pepper yellow leaf curl disease on C. frutescens.
