Abstract

The purpose of this study was to determine the productivity and adaptability of ten soybean genotypes in red-yellow podzolic soils. The experiment conducted in Balunijuk village, Merawang subdistrict, Bangka on July-October 2010. Experimental design used randomized complete block design with 10 genotypes soybean replicated three times. Tested genotypes consisted of six promising lines (KH 8, KH 9, KH 31, KH 38, KH 55, and KH 71) and 4 national varieties (Slamet, Anjasmoro, Wilis and Tanggamus) as comparison. The results indicated that there were significant differences among genotypes for character plant productivity, seed size, plant height, number of root nodules, effective number of root nodules, number of pods, number of productive branches, and sheer number of seeds. Entire promising lines tested had a larger grain size than the check varieties, and the largest grain size and the highest productivity was obtained in KH 71. Therefore, KH 71 considered more promising to be released as new varieties for red-yellow podzolic soils.

Abstract

Optimization of planlets growth during acclimatization can be done by using plant growth regulator. This research was aimed to know the effect of two foliar fertilizer and benzyladenin on the growth of Phalaenopsis hybrid orchid planlets during acclimatization stage. The treatment was Growmore and Bayfolan as the foliar fertilizer with the various concentrate of benzyladenin (BA) at BA 0 mg/l, BA 15 mg/l and BA 30 mg/l. The results showed that Growmore foliar fertilizer had the better response of plant height and fresh weight plant compared to Bayfolan foliar fertilizer. BA 30 mg/l was increased the leaf number, and BA 15 mg/l and 30 mg/l was decreased root length and fresh weight plant. There was no interaction between foliar fertilizer and benzyladenin on the growth of Phalaenopsis hybrid orchid planlets.

Abstract

Utilization of waste chicken feather and crab shells as compost material is an alternative to reduce the environmental pollution caused by waste. This research is identify and study the effect of the addition of crab shells during composting of chicken feather in improving the physical and chemical quality compost chicken feather. The composition compost consists of 1.75 kg of chicken feathers  + 0.15 kg of chicken manure + 0.1 kg bran. Treatmentincludesresearch R0 without the addition of crab shells, R1 0,2 kg, R2 0,4 kg, R3 0.6 kg shell crab. This research used a cluster randomized design (RAK) consisting of 4 treatment, which was repeated 3 and each treatment has 3 samples, 36 samples were obtained observations.

Abstract

Bangka Island is known to have red-yellow podzolic soil type with acid characteristic and is rarely to take as agricultural land. Planting cassava in local area might be a source for local food needs diversify. The purpose of this study was to determine the productivity of the 10 genotypes cassava landrace on red-yellow podzolic soils type. The experiment conducted in the Balunijuk village, Bangka as reference. Experimental design used randomized block design with 10 genotypes Bangka cassava landrace (Upang, Sekula, Bayel, Mentega, Kuning, Batin, Pulut, Sutera, Rakit and Selangor) as treatments. The results showed that 10 genotypes cassava tested produce well on a red-yellow podzolic soils. Morphological analysis performed on tuber parts of Bangka cassava landrace showed outer skin color, skin and tuber flesh color were vary among genotypes. Sutera had the highest tuber production for 2960 g/plant. Cluster analysis based on isozyme markers divided in two groups with similarity coefficient of 0.742. First group consisted of genotype upang, bayel, mentega, pulut, and sutera. Second group consisted of genotype sekula, batin, kuning, rakit, and selangor.

Abstract

In order to fulfill food needs, we need another food resources beside rice. Cassava (Manihot esculenta L.)  is one of the sources food that substitutes the rice. Beside that, utilization of ultisols as cropland can support the efforts to fulfill food needs. This study was conducted to determine the effect of giving Phosphate Solubilizing Fungi (PSF) to one variety (Malang 1) and three accesions of cassava (Sutera, Kuning, and Bayel) on planting in ultisol land. The experiment were conducted with a split plot design, where the main plot consists of PSF and non PSF, while the subplot consists of 1 variety and 3 accessions of cassava. The results showed that addition of Phosphate Solubilizing Fungi (PSF) gives good effects to some characters such as plant height, number of leaves, number of tuber, and tuber weight if compared without PSF. Furthermore, only the Kuning accesion that shows the interaction with PSF for the number of leaves character.
