Abstract

This study aims The Number of Seeds and Pruning of Maize Yields (Zea mayz L). The research was conducted in April to December in the village of Pandes, Wedi Subdistrict, Klaten Regency, Central Java Province. High land 115 m type soil Vertosol. This research used a completely random factorial 2 x 4 randomized Block design. The First factor is the number of corn seeds per planting hole (B), consisting of 2 levels B1: 1 seed per planting hole with a spasing (column) of 20 cm, B2: 2 seeds per planting hole white a inter spasing (row) 40 cm. The second factor is pruning (P), consisting of 4 levels: P0 white out pruning (control), P1 pruning leaves under the corn cob, P3 pruning male lowers (tassel) and P4 in combination. Results, all treatment parameter had no interaction, except the weight of corn seeds per cob. All treatment parameter was not significantly different except the weight of corn kernels per corn cob. The largest seed weight is the combination of B1P2 (183,93 grams per corn cob, number of seeds 1 grain planting hole with pruning of leaves and male lowers. The smallest seed weight is the combination of B1P0 (176,88 grams per corn cob, number of seeds 1 grain planting hole without pruning.

Abstract

The research titled the Inluence and haw to plant shallot (Allium ascalonium L.) on the result was conducted on March to October 2016 in BP3K Girimulyo, Girimulyo Kulon Progo with height of 250 m on soil type vertisol. The research used randomized block design arranged in factorial consisting two treatment factors with three replications. The irst factor (P) consists of 2 levels, P0=without cutting, P1= cutting 1/3 of tuber. The second factor of how to plant shallot consist of 4 levels, (S1)=spacing 20 X 20 cm population 177.778 clumps per hectar, (S2)= planting jajar lewogo 2:1 spacing 20 X 20 cm population 271.111 clumps per hectar, (S3) spacing 20 X 15 cm population 231.111 clumps per hectar, (S4)= planting jajar lewogo 2:1 spacing 20 X 15 cm population 351.111 clumps per hectar. The result showed there is interaction of second treatment to parameter of wet bulb weight per clumps highest (71.26 gram), parameter diameter of dry tuber treatment P1S1, P2S1 highest (19.65 mm, 19.95 mm). Conclusions of this study are: 1. On how to plant, cutting 1/3 of tuber tip gives good result to most of observation parameters; 2. The Tajarwo 2:1 system is better than the conventional system (non tajarwo) to shallot yield per plot of size 4,6 m2 parameter; 3. the Conventional system can increase the diameter of the shallot bulbs.

The results showed no interaction between the two treatments. Conclusions of this study are: 1. The addition of manure 100% or 4 part give the most of the number and weight of fruit per plant (planting medium soil: manure=1:1) 2. The addition of rice husks 50% or 2 part, give the most of the weight of fruit per plant (planting medium soil rice husks: manure=2:1). 3. There is no interaction of treatment to the number and weight of chilies per plant.

Abstract

The Research purpose was to study the arrangement of primary branch number and crop reduction on the yield and seed quality of Kaliurang tomato variety. A field experiment was conducted on regosol soil located in Agriculture Extension College Yogyakarta at 115 m above sea level (asl). The experiment was carried out following 3X3 factorial design arranged in Completely Randomized Block Design with 3 replications. The first factor was branch with 3 levels i.e. 1 primary branch, 2 primary branches and 3 primary branches. The second factor was reduction of tomato fruit set consisting 3 levels i.e. 0,96 reduction, 15% reduction and 30% reduction. The results show that 3 primary branch and 15 94, or 30 96 crop reduction best crop growth rate, leaf area index on 6 weeks plant growth. The treatment of 3 primary branches and 15% crop reduction gave the highest tomato yield per hectare. And the best weight of 1000 seeds was obtained front the combination of 1 primary branch with 30 % tomato reduction.

Abstract

Hubungan kekerabatan pada persilangan three-way terung dilakukan untuk membantu seleksi pedigree dengan perolehan galur bertipe “pondoh”. Persilangan antar tetua jantan ‘Lokal Gunungkidul’ dan tetua betina ‘Teho F1’ menghasilkan terung bertipe “pondoh” sebagai kajian dalam pengkayaan ragam tipe buah di Indonesia. Pengamatan dilakukan secara single plant dengan mengamati karakter tetua dan hasil persilangan sebanyak 100 populasi. Jarak koefisien antar tetua menunjukkan nilai sebesar 66,88, sedangkan antar tetua dengan hasil persilangan berkisar 9,69-36,69. Analisis clustergram menunjukkan adanya klaster tetua yang terbentuk pada nilai similaritas 0% – 5,96%. Adapun hasil persilangan membentuk klaster pada nilai similaritas 38,21 dengan bentuk buah ellipsoid dan 92,55% - 94,18% dengan bentuk buah obovate dan pear shaped (tipe “pondoh”). Hasil persilangan membentuk 4 klaster dengan nilai similaritas yang berbeda. Klaster AI dan BI menjadi pilihan dalam perolehan galur harapan terung tipe “pondoh” sebagai fokus bahan kajian dalam pemurnian galur generasi berikutnya.

Abstract

Cocopeat merupakan media tanam yang berasal dari sabut kelapa, dapat menyerap dan menyimpan air dengan baik serta memiliki pH bekisar antara 5.0-6.8, namun cocopeat memiliki kekurangan yakni mengandung zat tanin yang tinggi sehingga bersifat toksik bagi tanaman dan dapat menurunkan efisiensi penyerapan nutrisi. Penelitian ini bertujuan untuk mengurangi kandungan zat tanin dalam cocopeat. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan dua faktor perlakuan, yaitu lama perendaman cocopeat (0, 2, 4, dan 6 hari) dan dosis CaCO₃ (0, 0,5, 1, dan 1,5 gram/kg cocopeat). Percobaan terdiri dari 16 kombinasi perlakuan dan setiap kombinasi perlakuan terdapat 3 ulangan, sehingga total terdapat 48 unit percobaan. Hasil penelitian menunjukkan bahwa kandungan zat tanin perlakuan kombinasi perendaman 6 hari dan CaCO₃ 1,5 g/kg (D3P3) memberikan hasil terbaik dalam menurunkan kandungan tanin (hingga 639,33 ppm), dan Perlakuan meningkatkan pH media tanam (menjadi 5,53). Sementara itu, umur berbunga dan produksi benih per tanaman tidak menunjukkan perbedaan signifikan antar perlakuan.

Abstract

This study aims to analyze the factors that influence farmers' interest in participating in the Makmur Program initiated by PT Pupuk Indonesia and implemented by PT Petrokimia Gresik in Kalisoro Village, Tawangmangu District, Karanganyar Regency. This program is an effort to empower farmers through the provision of production facilities, technical assistance, and support for increasing productivity. The research method used is a quantitative approach with binary logistic regression analysis techniques. The number of respondents in this study was 70 farmers, who were taken proportionally from farmer groups that had and had not participated in the program. The results of the analysis show that of the six variables studied age, length of farming, productivity, agronomic role, role of farmer groups, and role of resource providers there are two variables that have a significant effect on farmers' interest in participating in the Makmur Program, namely age and productivity. The age variable has a significant positive relationship, which means that the older the farmer, the greater the tendency to participate in the program. Meanwhile, the productivity variable also shows a positive effect, indicating that farmers with high yields are more open to programs that support their farming efforts. Based on these findings, it can be concluded that the success of participation in the Makmur Program is influenced by internal factors of farmers, especially age and productivity achievement. The results of this study are expected to be the basis for policy makers in designing communication strategies and approaches that are more targeted to farmer groups.
