The Callosobruchus Spp. Controlled Using Soursop Seed Extracts by Several Organic Solvent on Mungbean Storaged Seeds

The aims of the experiment was to get extract of sour-sop plant part and the kind of organic solvents for decreasing Callosobruchus spp development on mungbean storaged seed. The experiment was conducted at Plant Protection Laboratory, Faculty of Agriculture, UPN “Veteran” Yogyakarta from March to August 2013. It consisted of two factors: the part of sour-sop plant powder (leaves, and seeds) and the kind of organic solvents (Petroleum-eter; Dietil-eter and methanol) and one control: no extract application. It was arranged in Randomized Complete Design with four replications. Data collected was subjected to an analysis of variance followed by DMRT at 5% significance level. The results showed that: 1) The seeds and leaves extract that being solved in organic solvent could supress Callosobruchus spp development better than the control (no extract). 2) The soursop seeds in methanol solvent could supress Callosobruchus development, weight loss of mungbean seed and seed conductivity.Keywords: sour-sop powder, Callosobruchus spp., organic solven

STUDY OF GROWTH YIELD AND SEED QUALITY OF CUCUMBER (Cucumis sativus L.) ON BIOFERTILIZER AND LIQUID SMOKE FERTILIZER

The application of biofertilizer and liquid smoke fertilizer is either method to increase the production of cucumber according to the environmentally friendly because it’s made from organic materials. The purpose of this research is to get the biofertilizer dose and the best concentration of the liquid smoke fertilizer to increase the growth and yield of fruit as well as the quality of seed cucumber. This research method is a field experiment that arranged by Completely Randomized Group Design (RAKL). The first factor is biofertilizer dose (P) that consist of 3 levels, that is: 5 ml/plant, 10 ml/plant and 15 ml/plant. The second factor is the concentration of the liquid smoke fertilizer (O) that consist of 3 levels that is: 1%, 2% and 3%. The control crops were fertilized according to the farmer’s habit of using NPK without biofertilizer and liquid smoke fertilizer treatment. The obtained data were analyzed by diversity analysis level 5%. To find out the significant differences between the control and the treatment, we did Contras Orthogonal Test level 5% and  Duncan Multiple Distance Test level 5%. The result showed that the combination of treatment was significantly better than the control. There is an interaction between the dose of  biofertilizer and concentration of liquid smoke on the vigor index parameter. The combination of P2O2 (biofertilizer 10 mL/plant and liquid smoke 2%) treatment is the best treatment on vigor index parameter.  The best P2 (dose of biofertilizer 10 mL/plant) treatment was on the parameter of fruit weight per plant. O2 (concentration of liquid smoke 2%) treatment was best on the parameters of fruit weight per swath

THE EFFECTIVENESS OF INNOVATION OF DRYING FLOOR ON THE DELAY OF DRYING POSTPONEMENT AND SEED LAYER THICKNESS TOWARDS VIGOUR AND GROWTH OF RICE SEEDS (Oryza sativa L.)

Drying is one of the important post-harvest activities. Limitations on the location of drying, labor and during the rainy season cause delays in drying. Delays in drying and improper seed layer thickness can reduce the quality of the resulting seed. The purpose of this study is to determine the time delay for drying and the maximum thickness of the seed that did not reduce the viability and growth of rice plants. The study used the innovation drying floor of UPT BBP Barongan, Bantul and Split Plot Design with 2 factors. The first factor as Main Plot was the treatment of drying delay: 2.4 and 6 days. The second factor as a sub plot is the thickness of the seed layer: 3, 5, 7, and 9 cm. The treatment is repeated 3 times. The research data were analyzed with Analysis of variance 5% and further tested with DMRT 5% (Duncan's Multiple Range Test). The results showed that the treatment of delaying drying for up to 6 days and the thickness of the seed drying layer up to 9 cm can be tolerated with innovative drying tools so it does not reduce the seed vigour and growth of rice plants. Keyword: drying delay, seed layer thickness, innovation drying floor, rice vigour and growt

WATER DEFICIT EVALUATION ON SEED VIABILITY AND VIGOUR OF VARIOUS CHILI VARIETIES (Capsicum annum L.) USING VARIOUS CONCENTRATION OF PEG 6000 IN GERMINATION AND GROWTH PHASE

The research was carried out to find out chili varieties which gave high seed viability and vigour on germination and growth phase in water deficit evaluation using PEG-6000. There were 2 experiments, the first experiment was 4x10 Factorial arranged on Randomized Complete Design with three replicates using petridish. The first factor was PEG-6000 concentration of: 0%, 10%, 15% and 20%. The second factor was chili varieties namedly TM 33 , TM 99, Kastilo , OR Doni 77 , OR Twist 42 , Kaka 99 , OR Twist 22, Red sabel, Rimbun 3, Amro 99. The second experiment was 6x2 Factorial arranged on Randomized Complete Design with four replications using polybag. The first factor was chili varieties which had high viability and vigour on first experiment: TM 33 , Kastilo , OR doni 77, OR twist 22 , Red sabel and Rimbun 3 varieties. The second factor were normal and deficit watering. The data was subjected to an analysis of variance followed by Duncan’s Multiple Range Test and LSD 5%.The results indicated that TM 33, Kastilo, OR twist 22, Red sabel and Rimbun 3 had high viability on germination phase in water deficit evaluation using PEG-6000. TM 33, OR twist 22 and Rimbun 3 had tolerance growth in deficit watering.Keywords: chilli, water deficit, PEG-6000, viability, vigo

APPLICATION OF NATURAL PLANT GROWTH REGULATOR AND COW BIOURINE ON GROWTH AND YIELD OF SHALLOT IN RAINY SEASON (Allium cepa L.)

The use of natural hormones of young sweet corn extract, coconut water extract, and banana stem extract and application of cow biourine has been introduced as an innovation to reduce the use of chemical fertilizers to increase the productivity of shallot. This study aims to compare the growth and yield of shallot with chemical fertilizer treatment and that of shallot treated with a combination of the natural hormone and cow urine. The study was conducted from October 2019 to January 2020 in Temon Wetan, Temon, Kulon Progo, Special Region of Yogyakarta using a Complete Randomized Block Design, which consists of two factors and one control (chemical fertilizer). The first factor is a natural hormone: young sweet corn extract, banana stem extract, and coconut water. The second factor is the concentration of cow urine: 30%, 40%, and 50%. Data were subjected to an analysis of variance followed by Duncan’s Multiple Range Test and Orthogonal Contrast at 5% It was revealed that the control group with combined treatments was not significantly different from the growth and yield of shallot of the group with chemical fertilizers. Types of treatments with natural hormone and cow urine concentrations provided the same growth and yield as that of chemical fertilizer
