Abstract

Organic cultivation in egroforestry system by biofertilizer potentialy conducted for soybean.  Soybean cultivation in agroforestry system there are several limitations but it have to effort since the area of ideal land decreasing year by year.  The aim of the research by experiment method is increasing yield of soybean by organic cultivation in agrofrestry system either quality or quantity.  The experiment design is randomized block design (RBD) with two factor trearments.  The first factor are kinds of variety (Grobogan and Local) as mainplot and the second one are biofertilizer duration (no biofertilizer as control, 4, 5, 6, 7 weeks applies ones a week).  So there are 10 combination treatments and replicated three times for each of them.

Abstract

The study aimed to determine which substrate and nutrition that gives the best result in improving growth and yield of Capsicum frutescens. The study design using CRD (completely randomized design) with two factors, namely substrates (6 levels: charcoal husks, fractional tiles, fractional bricks, arenga fiber, beach sand, husk steamed) and nutrition (2 levels: standards, standards with NPK). The study was conducted October 2015 until March 2016 in screen house Faculty of Agriculture, Sebelas Maret University. Data were analyzed using analysis of variance and if significant difference continued with DMRT (Duncan Multiple Range Test) level of 5%. The results showed that the kinds of substrates significantly affect all variables of Capsicum frutescens (plant height, leaf number, branch number, total interest, diameter trunk, root length, root volume, fresh weight of plants, plant dry weight, fruit weight and number of fruit), and the addition of NPK nutrition significantly affect variable leaf number, branch number, and fresh weight of plants.

Abstract

The research aims to assess the yield of baby kale that can be consumed almost all of the parts and generate organic manure free. Field research was conducted in Sindon Village, Ngemplak, Boyolali in September to October 2016. The research method uses Randomized Complete Block Design factorial with two factors, these are the dosage of manure and the age of harvest. Manure consisted of 4 doses O1 (0 ton/ha), O2 (6 tons/ha) and O3 (8 tons/ha) and O4 (10 tons/ha), and age of harvest consisted of P1 (16 DAS), P2 (20 DAS), and P3 (24 DAS). Variables observed were plant height, number of leaves, internode length, fresh weight, dry weight, leaf area index, and harvest index. The result showed that age of harvest has significant influence plant height, internode length, the number of leaves, leaf area index, fresh weight, dry weight, and harvest index. Manure doses only influence dry weight. Manure dosage of 8 ton/ha and harvest age of 16 DAS is the best combination of baby kale. Manure dosage of 10 ton/ha and harvest age of 16 DAS produce baby kale that can be consumed almost in all parts of the plant with the highest harvest index that is equal to 0.83.
