Abstract

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 growth

Abstract

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, vigor

Abstract

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 solvent
