Abstract

The research aimed to identify (1) the attractiveness of leaf extract of Ocimum sp. and M. bracteataon fruit flies in chili plantation and (2) species of fruit flies collected from the plantation. The studywas conducted from March to April 2009 using a Completely Randomized Block design with 3treatments of traps and 4 replications. The results showed that leaf extract of Occimum sp. and M.bracteata were effective attractants for trapping and controlling fruit flies at the chili plantation.The number of fruit flies trapped on both attractant was significantly higher compare with thattrapped on control (without attractant) but M.bractetata extract showed a higher attractiveness tofruit flies compare with Occimum sp. extract. However, the effectiveness of those attractants wasdecreased with time. The species of fruit flies recorded was Bactrocera dorsalis Hendel.Key words: Attractans, fruit flies, Occimum sp., M. bracteates.

Abstract

The aim of this research was to determine the effect of inorganic fertilizer proportion and organic fertilizer as well as its interaction to N uptake, N uptake efficiency, and physiological characters of rice plant. This research was conducted in the Experimental Farm of Agriculture Faculty of Jenderal Soedirman University Purwokerto, with soil type used was Inceptisol and located 110 m above sea level. This research was arranged using split plot design with four replicates. The main plots were the type of organic fertilizers i.e cow manure 5 t/ha, and straw compost 5 t/ha. The subplots were the proportion of inorganic fertilizers i.e P1: general dose recommendation (250 kg Urea, 150 kg SP-36 and 150 kg KCL), P2: 75% of general dose recommendation (187.5 kg Urea, 112.5 kg SP-36 and 112.5 kg KCL), P3: 50% of general dose recommendation (125 kg Urea, 75 kg SP-36 and 75 kg KCL), P4: P and K according to soil nutrient status + N according to Leaf Color Chart scale (LCC), P5: 150 kg SP-36, 150 kg KCl, and N according to LCC scale, and control (without fertilizer). The observed variables were leaf area index, leaf greenness, leaf chlorophyll content, N uptake, and N uptake efficiency. Data was analyzed using F test and if the differences were significant, the analysis was proceed with DMRT test at 5% error levels and orthogonal contrast test. The results showed that the dose of inorganic fertilizer increased the leaf area index, chlorophyll content, N uptake and N uptake efficiency. The reduction of inorganic fertilizer dose up to 50% of general dose increased the content of chlorophyll a. N uptake efficiency was higher in the N fertilizer added based on LCC and P and K based on soil nutrient status treatment than the recommendation dose when straw compost was applied.

Abstract

The experiment was conducted on the Technical Irrigated Rice Field in D.I. Yogyakarta with soil type is Regosol. The study took place in July to December 2010. The research aim was to obtain agronomic characters and optimal planting distance that could increase the productivity of land with furrow irrigation system (FIS). The research used a factorial design (2 x 4+2) with 3 replications. Factor 1 was cultivars (K): K1 (Cimelati) and K2 (Sarinah). Factor 2 was planting distances (J): J1 (20 x 20 cm), J2(20 x 15 : 40 cm; legowo 2:1), J3(20 x 12,5 : 40 cm; legowo 2:1), and J4(20 x 12,5 : 45 cm; legowo 2:1). Controls were Cimelati and Sarinah cultivars grown in wetland rice field. The experimental results showed that the ability of plants to form seedlings in FIS was better than in the rice fields. The ability of plants to form seedlings in FIS at different planting distances was similar. Net assimilation rate (NAR) and relative growth rate (RGR) in the wetland system was better than FIS, but the leaf area index (LAI) and crop growth rate (CGR) was better in FIS. The NAR, RGR, and CGR in both systems were similar. Larger panicle and grain panicle number, 1000 grain weight and percentage of filled grain rice were found in FIS than in the rice field. The growth of rice in FIS was not affected by differences in both cultivars and planting distance. Dry harvested grain weight in FIS was lower than in the rice field. Dry harvested grain weight of Cimelati cultivar (8.04 t/ha) in FIS with planting distance of 20 x 12,5 : 40 cm (legowo 2:1) was comparable with that in the rice field (8.05 t/ha).

Abstract

The aim of this research was to find the culture technology of organic rice production based on liquid organic fertilizer and botanical pesticide with high yield and efficiency. This research was conducted at Purwosari Village, Baturaden Subdistrict, Banyumas Regency, Central Java from August to November 2010. This research was arranged using a Randomized Completely Block Design with seven cultures of organic rice production technology as the treatments. The agronomic variables were plant height, number of tillering, and rice yield (ton/ha). Financial variables were fixed cost, variable cost, and farming revenue. The agronomic variables were analyzed by F test, and if the effect of the treatments were significant the analysis was proceed by Duncan’s Multiple Range Test at 5% level. The financial variable was analyzed using R/C analysis, profit rate analysis, and break even point analysis. Results of the research showed that the assembly of the organic rice production technology which was the most efficient in maintaining high production was the technological assembly with component of straw + cow manure of 5 tons/ha per ha + soil liquid organic fertilizer (LOF) (4 ml/l) + leaf liquid organic fertilizer and botanical pesticide consisting of maja and gadung (6%) + biological agent of Trichoderma harzianum (10 ons per plot) at 2 days after planting with the production level 0f 5.04 tons/ha, and the profit rate of 92.35% and the technological assembly with component of straw + cow manure of 5 tons/ha + soil LOF (4 ml/l) + the combination of leaf LOF + botanical pesticide of maja and gadung (6%) + fermented of palm juice (applied on 45 and 55 days after planting) with the production level of 4.6 tons/ha and the profit rate of 81.73%.

Abstract

The experiment of applying several kinds of media compositions and doses of KCl fetilizer aimed to determine media composition and potassium doses best for tomato plant (Lycopersicon esculentum Mill.) growth and yield. This experiment was conducted on February until Juny 2011 at “Balai Benih Induk Hortikultura” farm (± 625 m above sea level), Ngipiksari, Kaliurang, Sleman, Yogyakarta. The experiment used a Completely Randomized Factorial Design with three replications. The first factor was kinds of planting media composition (v/v/v): M1 =soil:goat faeces:sand (1:1:1); M2= soil:goat faeces:sand (2:1:1); and M3= soil:goat faeces:sand (1:1:2). The second factor was doses of potassium: D1 = KCl 75 kg ha-1; D2 = KCl 100 kg ha-1; = KCl 125 kg ha-1; and D4 = KCl 150 kg ha-1. The results of experiment showed that there is significant interaction between media compositions and doses of potassium on plant dry weight, and fruit diameter and thick. The M2D3 treatment resulted in highest contens of vit. C while the M2D2 in sugar content. The M1D1, M2D3, M3D2, and M3D3 treatments produced better taste than the others. The vegetatif growth (plant height, flowering time and harvest time) was only significantly affected by the media composition while the fruit yield by potassium fertilizer in which largest yield was found in the D3 treatment (3.75 g plant-1).
