Chili (Capsicum annuum L.) is one of the horticultural commodities that have high economic value which is used as vegetables or cooking spices, industrial raw materials, and has export opportunities. The development of superior chili varieties requires a large variety of germplasm that can be used as parents to be crossed with each other to obtain new superior traits. One of the efforts to determine the diversity of plants is to characterize the morphology and production. The purpose of this study was to obtain distinguishing characters among ten genotypes of large chilies, to determine the value of genetic parameter estimators for several genotypes of large chilies and to identify important characters that influence the yield of large chili genotypes. The study was a single factor field experiment in the form of 10 large chili genotypes arranged in a Completely Randomized Block Design (RCBD) with 3 blocks as replication. Genotypes of large chili are: Arimbi, Baja, Beautiful, Dewa Rengku, Gada, Jayadi, Jenio, Simpatik, Panex, and Thunder. Observation variables included morphological characters (plant habit, leaf color, leaf position, leaf shape, flower position, anther color, pistil color, leaf edge, fruit color), growth variables (plant height, stem diameter, number of leaves), and yield variable (weight per fruit, fruit length, fruit weight per plant). The results showed that all morphological characters for all varieties were the same, namely having an upright habitus, pointed leaf shape, green leaf color, leaf position falling, flower position lowering, purple anther warrant and green pistil stalk warrant, and red fruit skin color.

Maize (Zea mays L.) is one of crops that source of carbohydrate than rice. The maize production needs to production goal. The problems is traditional variety haved low yield. This study aims to determine the agronomic character and potential yield of several hybrids maize.. The research method used was randomized completely block design was repeated 3 times. The treatment factor namely hybrid maize genotype. The data obtained were analyzed in theirs diversities by using variace at 5 % level, if there were significant difference, continued by using the least significant increase at 5% level to compared of variety tester. The results shows that hybrid maize genotypes, G2KPW-43, G2KPW-45, and G2KPW-48 haved superiorities in agronomic character and higher potential yield.Key words: genotypes, potential yield, maize

Salah satu inovasi untuk mengurangi serangan penyakit di musim penghujan dan penggunaan pupuk kimia dalam meningkatkan produktivitas bawang merah yaitu dengan menggunakan varitas berumur pendek dan zat pengatur tumbuh alami ekstrak jagung manis muda, ekstrak air kelapa, dan ekstrak batang pisang serta pemberian biourin sapi. Tujuan penelitian adalah membandingkan pertumbuhan dan hasil tanaman bawang merah dengan perlakuan pupuk kimia dan kombinasi zat pengatur tumbuh alami plus biourin sapi. Penelitian dilaksanakan pada bulan Oktober 2019 sampai Januari 2020 di Temon Wetan, Temon, Kulon Progo, Daerah Istimewa Yogyakarta. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap, yang terdiri dari dua faktor ditambah satu kontrol (pupuk kimia). Faktor pertama adalah zat pengatur tumbuh alami: ekstrak jagung manis muda, ekstrak batang pisang dan ekstrak air kelapa. Faktor kedua adalah konsentrasi biourin sapi: 25%, 50%, dan 75%. Data dianalisis dengan analisis keragaman pada taraf 5%, Contras Orthogonal pada taraf 5% dan Uji DMRT dengan taraf 5%. Hasil penelitian menunjukkan bahwa kontrol dengan kombinasi perlakuan tidak berbeda nyata terhadap pertumbuhan dan hasil bawang merah. Jenis perlakuan zat pengatur tumbuh alami dan konsentrasi biourin sapi memberikan pertumbuhan dan hasil bawang merah yang sama.

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

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
