Potatoes (Solanum tuberosum L.) highly consumed in the form of vegetable and processed potato so that the needs of potatoes have not been fulfilled by domestic production. One effort to increase national potato production is to assemble high-yield varieties of potato. This study aimed to test the production of several IPB potato promising clones. This research was conducted in Garut, West Java in May to August 2016. This research used Completely Randomized Design with clone as the factor and repetition as many as three replications as the group. The planting material used was IPB Potato promising clones which consisted of PKHT 2, PKHT 4, PKHT 6, PKHT 9, and PKHT 10 and Granola and Atlantik as the comparison. The results showed that PKHT 4, PKHT 6, PKHT 9, and PKHT 10 are IPB potato promising clones that have high production equivalent to Granola and higher than Atlantik as commercial varieties. Based on physical criteria PKHT 4 and PKHT 6 suitable to be processed potato chips and PKHT 9 and PKHT 10 suitable to be vegetable potato.Keywords: atlantic, granola, potato as vegetable, processed potato

This research was aimed to determine the effect of the PGR 2.4-D (Dichlorophenoxy Acetid Acid) in various concentrations on induceing callus of Dombu potato (Solanum tuberosum L.). This research was performed based on Completely Randomized Design (RAL) with 6 treatments and 3 times repetation, so there were 18 experiment units. Each experiment used 3 explants so as there were 54 explants. The combination of concentration of the tested PGR in the culture media were T1 = MS0+ 2.4-D 0 ppm (control), T2 = MS0+ 2.4-D 0.5 ppm, T3 = MS0+ 2.4-D 1 ppm, T4= MS0+ 2.4-D 1.5 ppm, T5 = MS0+ 2.4-D 2 ppm and T6 = MS0+ 2.4-D 2.5 ppm. The results showed that callus induction was appeared in the concentration of 1.0, 1.5, 2.0, and 2.5 ppm. Callus was generally formed on the Day-8 after plantation. Callus color was mostly greenish transparent, callus texture was mostly crumb type, and callus formation percentage was almost 100%. The best media for inducing the callus was in treatment T4 (1.5 ppm 2.4-D), it referred to the formed callus biomass

ABSTRACT Brazil is the second largest soybean producer in the world, with a yield of around 96.2 million tons per crop. This high yield leads to a great amount of waste resulting from soybean cultivation, which can reach approximately 41 million tons of waste per year. This material has lignocellulosic properties, which may enable its use as a raw material for particleboard production. Therefore, the objective of this study was to evaluate the use of soybean pods in particleboard production. For particleboard manufacture, wood of the hybrid Eucalyptus urophylla and Eucalyptus grandis was used, added with soybean pods, at proportions of 0%, 25%, 50%, 75% and 100%. For particleboard evaluation, a completely randomized design was used, with five treatments and three replicates, using linear regression and the Scott-Knott test at 5% significance for comparison among the different treatments. The properties apparent density, compaction ratio, water absorption after 2 and 24 hours, thickness swelling after 2 and 24 hours in water immersion, internal bonding, modulus of rupture and modulus of elasticity in bending properties were evaluated. The ratio soybean pod waste and eucalyptus particles in the panels led to an increase in water absorption values and thickness swelling, in addition to a decrease in mechanical properties. The production of panels with approximately 23% soybean pods is feasible.

An experimental trial was conducted to find out the effective potting mixture and low cost quality planting material through semi-hardwood cuttings propagation of endangered medicinal plant Commiphora wightii (Arn.) Bhandari. The experiment was carried out in CRD (Completely Randomized Design) with six treatments, three replications and 20 cuttings per treatment. Growth in cutting was measured by eleven parameters. Parameter such as sprouting percentage (88.67%), rooting percentage (83.45%), minimum days for sprouting (9.82), number of sprouts (7.17), length of shoot (15.25cm), diameter of shoot (3.950mm), number of leaves (24.83), chlorophyll content a, b and total (7.6290, 5.7083 and 13.3374 mg/100g, respectively) was significantly superior under potting mixture S+S+V (soil+sand+vermicompost). Furthermore rooting parameter such as number of roots (7.51), length of root (14.60cm), diameter of root (1.338mm) was found higher in media containing S+S+C (soil+sand+cocopeat).

Background: In a Mediterranean agrosystem of low productivity, a study was carried out on the effects of municipal solid waste compost (MSWC) compared to other organic and inorganic amendments on the production, quality and yield of three potato varieties (Solanum tuberosum L.) and an advanced clone. Method: Simultaneously, the agronomic and nutritional parameters of the potato crop, the degree of bioavailability and the possible risks of heavy metal contamination were studied. Results: Two stages are observed in the yield and content of macro, micronutrients and heavy metals. The addition of all amendments and especially that of urban waste compost increased potato production and the content of macronutrients, micronutrients and heavy metals in the soils of all varieties, showing a progressive accumulation in tubers. Nevertheless, the performance is not maintained over time with a notable decrease during the second stage of its application. Conclusion: Highlighting the potato clone A7677 not only in its performance but also in the concentration of iron, zinc, copper, essential micronutrients for human consumption and especially for populations deficient in these trace elements.

Seven quantitative traits of the cultivated potato (Solanum tuberosum L.) were studied in a partial diallel cross experiment. Large specific combining ability effects were observed for total and marketable yields, total number of tubers, and number of marketable tubers. Large general combining ability effects were obtained for average weight per tuber, average weight per marketable tuber, and specific gravity. The SCA effect for specific gravity was also significant. It is suggested that the difference of combining ability performance noted above for the two yield components was due to a long history of directional selection for high yield and stabilizing selection for tubers within the marketable size range. There were low frequencies of both GCA and SCA effects showing significant difference from the population mean. This is interpreted as an affirmation of the narrow genetic base which exists in the present gene pool in Solanum tuberosum. Heritability estimates based on GCA effects indicated that parents can be efficiently selected for average tuber weight and specific gravity.

Set Up

Pest is one of the biological limiting factors that led to low production of potatoes. The use of pesticides is a solution in controlling pests. The objective of this study was to determine the diversity and evenness of insect; and potato yield losses due to insecticide applications methods. The treatment was controlled and intensive insecticide application which were compared with no insecticide application.  The experiment was set up in completely randomized design with five replications. The results showed that the insects are dominated by Empoasca sp, Liriomyza sp and Miridae. The highest insect population was Empoasca sp. i.e 80.83 Empoasca sp. which was found in control treatment. Controlled and intensive  application of insecticides decreased insect  population up to 56.50 and 26.17. Evenness index of insect and economic value of lost results unaffected by differences in pesticide application methods
