Abstract

Katuk (Sauropus androgynus (L.) Merr.) is an indigenous leafy vegetable whose growth is affectedby nitrogen element. This study was aimed at assessing the agronomic performance of four katukaccessions grown with various rates of cattle urine. A factorial completely randomized design wasused. The first factor was katuk accession consisting of four levels, namely Pandeglang, Cianjur,Sukabumi, Leuwiliang, and Kemang. The second factor was cattle urine rates consisting of 5 levels,namely 0%R cattle urine (0.0 ml/plant), 50%R cattle urine (468.75 ml/plant), 100%R cattle urine(937.50 ml/plant), 150% R cattle urine (1406.25 ml/plant), and 100%R urea (8.2 g/plant). Thegrowth and productivity of katuk of Cianjur accession had the highest number of buds, total lengthof buds, number of leaves, number of leaflets, fresh weight, and dry weight. The utilization of 50%R,100%R, and 150%R of cattle urine was found to have higher fresh and dry weight than did theutilization of 0%R cattle urine and 100%R urea. The best quality katuk was Cianjur accessionwhich was found to have the highest vitamin C and chlorophyll contents. No significant effects ofall treatments were found in all vegetative variables except plant height and root fresh and dryweight. It was concluded that cattle urine could be used as a urea substitute.Key words: Sauropus androgynus, number of buds, dry weight, indegenous plant

Abstract

The research aims to determine the prey abilily and preferences of Harmonia axyridisagainst Mizus persicae on citrus. The study was conducted at the screen house and EntomologyLaboratory of the Research Institute for Citrus and Sub-Tropical Fruits, in January-March 2016.The test for prey ability used the first larval stage of H. axyridis to imago for 30 individuals in eacharena. Data were analyzed by counting of M. persicae which eaten per day from each stage, i.e.larva instar, and H. axyridis imago, as well as the average prey during their life cycle. The resultsshowed that the highest prey of H. axyridis occurred in instar larvae 4, which reached 428.3% ofis body weight, with a number of preys 9.81 ± 1.01 head / day. Preferences of H. axyridis in instarslarvae 1,2, and 3 were instar nymphs 1 from M. persicae, and for H. axyridis the instar larvae 4and imago preferred of instar nymph 4. H. axyridis had a life cycle with a range of 6.6 -9.7 days.The duration of egg stage of the H. axyridis was 3 days, the larvae consisted of 4 instars, theduration of the stage for each instar was 2.4 days for instar 1 and 2; 5 days for instar 3; 12 daysfor instar 4, and 18.5 days for imago.Keywords: Prey, predator Harmonia axyridis, Mizus persicae, citrus

Abstract

This study was conducted at the experiment garden of Agrotechnology Department, DjuandaUniversity, Bogor, from July to September 2018. The study was aimed at assessing the effects ofthe application of nitrogen fertilizer and mung bean sprout extract on the growth and productionof edamame (Glycine max L. Merril) plants. The experimental design used was a factorialcompletely randomized design. The first factor is the dose of N fertilizer with four levels, namelywithout N (0 kg N / ha), a half recommendation of N fertilizer (34.5 kg N / ha), one recommendationof N fertilizer (69 kg N / ha), and one and a half recommendation of N fertilizer (103.5 kg N / ha).The second factor is the concentration of mung bean sprout extract with four levels, namely withoutmung bean sprout extract (0g tauge extract / l water), a half recommendation of mung bean sproutextract (75g tauge extract/ l water), one recommendation of mung bean sprout extract (150g taugeextract / l water) and one and a half recommendation of mung bean sprout extract (225g taugeextract/ l water). The results showed that the dose of N fertilizer significantly affected the widestleaf area. The concentration of mung bean sprout extract significantly affected the number of shootsat 6 and 7 weeks after planting (MST).Keywords: edamame soybean, N fertilizer, mung bean sprout

Abstract

Diaphorina citri is an important pest in citrus plants because of its role as a vector of CitrusVein Phloem Degeneration (CVPD) disease. The study was a follow-up test of the preliminarytests carried out previously. The aim of this study was to determine the effective concentrationof bioinsecticide of Japansche Citroen (JC) orange peel extract in controlling D. citri in thephases of nymph and imago. The concentration tested was 0% (control); 0.01%; 0.1%; 1%;and 10% (v / v) with a comparison of imidacloprid insecticide 0.1%. The test results showedthat the JC citrus peel extract at a concentration of 0.1 effectively controlled the D. citri nymphstarting at 96 hours after application (HAA) with a mortality of 69%. The concentration of 1%was effective from 24 HAA with a mortality of 65% and thereafter reaching up to 100% at 120HAA, this was not significantly different from the 10% concentration treatment andimidacloprid insecticide 0.1%, yet was significantly different from other treatments andcontrols. Citrus peel extract was effective for controlling imago of D. citri on 10% concentration. The concentration that was able to provide mortality above 50% was the highestconcentration of 10% at 96, 120 and 144 HAA. The results of the probit analysis showed thatthe LC50 values at 24 HAA on nymphs was 1.86 and the LC90 value was 9.10. The treatment onimago the LC50 at 48 HAA was 21.34 and the LC90 was not achieved. The results of thecalculation of the LC50 and LC90 values showed that the value in nymphs was smaller than inimago. This showed that the bioinsecticide of JC citrus peel extract was more effective againstnymphs than imago of D. citri. Bioinsecticide of JC citrus peel extract was effective againstpsyllid nymph of D. citri at concentrations of 0.1 and 1% and against the imago phase waseffective at 10%.Keywords: Toxicity, citrus peel extract, Diaphorina citri

Abstract

The research had been done in Nagari Ikur Lubuk Padang Panjang East District, Padang PanjangCity, with a height of 720 m above sea level. The experiments were conducted on March 2017-July2017. The aimed of this research was to obtain the best variety of rice and liquid organic fertilizerto produce a good forage feed. The experiments were arranged in a split-plot, the main plot beingthe rice crop; Cisokan and Pandan Wangi. The subplot consists of three types of organic liquidfertilizer (OLF), namely; Crocober Plus, Unitas Super, and NASA Commercial LOF replicate 3times to 18 plots. Forage pruning was done at 30 days after cutting ratoon. The data obtainedwere analyzed by F test 5% real level, if the treatment had real effect followed by SignificantDifference (LSD) test 5% real level. The included proximate analysis, digestibility of crudeprotein, fat, crude fiber, organic matter, dry matter, acid detergent fiber (ADF), neutral detergentfiber (NDF), hemicellulose, cellulose, and an extract substance without nitrogen. The results canbe concluded that the Pandan Wangi rice is able to produce the highest fresh weight of forage feedif given by 10% OLF of a Unitas Super.Keywords: Cisokan, forage animal feed, organic liquid fertilizer, Pandan Wangi, ratoon rice crop

Abstract

Basil is not only useful as a vegetable, but also has many medicinal properties. This encourages thedevelopment of environmentally friendly basil cultivation, through the use of natural fertilizers.This study aims to determine the response of various basil accessions to the composition of sourceN fertilizer derived from cow urine, kipahit (Tithonia) compost and Urea. The study was conductedwith a factorial completely randomized design. The first factor is the accession of basil, namelyKemang, Ciaruten, Cijujug and Gasol. The second factor is the combination of N fertilizer (10levels), namely 100% N-Urea, 100% N- cow urine, 100% N-kipahit, 75% N-Urea + 25% N- cowurine, 75% N-Urea + 25 % N-kipahit, 50% N-Urea + 50% N-urine cow, 50% N-Urea + 50%kipahit, 25% N-Urea + 75% N-cow urine, 25% N-Urea + 75% N - kipahit, 0% N-Urea + 0% Ncow urine + 0% N-kipahit. The dosage of N fertilizer used is 150 kg N ha-1. The results showedthat the accession of basil which showed good growth and production was 'Ciaruten' and 'Gasol'.The application of Urea fertilizer composition with kipahit compost and Urea with cow urineproduces better growth and production compared to the use of Urea fertilizer or organic fertilizerseparately.Keywords: basil, cow urine, kipahit compost
