Abstract

An experiment in greenhouse was conducted to study the effect of biochar and fertilizer potassium against leaching and uptake of potassium on the growth of maize during the two cropping seasons. In the experiment, a randomized block design with seven treatments and three-time replication was applied, namely control (without biochar and KCl), biochar (30 t ha-1) with various doses of potassium fertilizer (0, 50, 100, 150 and 200 kg KCl ha-1) and potassium fertilizer treatment of 200 kg KCl ha-1 without biochar. The first planting used 90 kg N ha-1 basic fertilizer and 100 kg P2O5 ha-1, while the second planting fertilizer was added with 90 kg N ha-1. The results showed that biochar containing potassium was soluble and leached. The amount of potassium leached from the soil given the biochar 30 t ha-1 did not differ from that given 200 kg KCl ha-1. The amount of potassium leached was not different, ranging from 439-449 mg l-1 in the first growing season (MT I) and 16-23 mg l-1 in the second growing season (MT II) at various doses of KCl with biochar.Keywords: biochar, leaching, potassium, uptake

Abstract

The best rubber planting materials are needed to build the best rubber plantation. Humic acids could be used to improve the growth of rubber planting materials. Humic acid plays a role as a hormone-like substance. This research was aimed to determine the optimal concentration of foliar application of humic acid in order to enhance the growth of rubber tree planting materials. This research was arranged in a completely randomized block design with five treatments and four replicates. The treatments were the concentrations of humic acids, i. e. 0; 250; 500; 750; and 1,000 ppm. Observations were made on rubber tree diameter, plant height, shoot and root biomass, and nutrient content of leaves and the stem. The results showed that foliar application of 1,000 ppm of humic acids could enhance the growth of rubber tree planting materials. Foliar application of 500 – 1,000 ppm of humic acids could increase K content of the stem. The effects of foliar application of humic acids were more apparent in the root part than in the shoot part.Keywords : Hevea brasiliensis, humic acid, growth, hormone, nutrient uptake, and planting materials

Abstract

Providing virus free potato seeds in order to increase potato production in Indonesia could be carried out by using microtuber resulting from microcutting. The growth of single node microcutting potato can initiate microtuber formation when growth inhibiting substances such as alar in combination with dark photoperiod treatment is applied. This study was aimed to elucidate the effect of alar and dark photoperiod on the date of microtuber emergence and production. The experiment was arranged in a factorial Randomized Completely Block Design in which alar concentrations i.e. 0, 10-3, 5 x 10-3, and 10-2 mg/L, served as factor I, and dark photoperiods i.e. 16, 20, and 24 hrs/day, were used as factor II. Each treatment combination was replicated three times giving rise to 36 experimental units. Data were analyzed using ANOVA (F test) followed by Duncan Multiple Range Test (DMRT) when significant effect of the treatments existed. The results showed that alar and dark photoperiod affected individually on the date of microtuber emergence, while the best alar concentration to increase microtuber production was 10-3 mg/L with 10.67 microtubers/cutting. Dark period has no significant effect on the induction of potato microtuber. Keywords: potato microtuber, alar, dark photoperiod

Abstract

The experiment was to determine the relationship between yield and yield contributing traits and select the promising genotypes. Twenty two genotypes and two check varieties were evaluated at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during Rabi season, 2008-2009 in a RCBD with three replications. Significant variation among the lentil genotypes were observed in respect of days to first flowering, days to maturity, plant height, pod/plant, 100-seed weight and yield. The genotype BLX-02009-06-3 flowered and matured earlier. Among the test entries, BLX- 02009-18-3 and BLX-02009-18-1 were tall. The highest number of pod per plant was obtained in BLX-02009-04-5. The large seed size was found in LR9-130 and LR9-25. The highest yield was found in BLX-02009-04-1 followed by BLX- 02009-04-5 than the two check varieties. Difference between genotypic coefficient of variation and phenotypic coefficient of variation was small for the traits as plant height, days to maturity, days to first flowering and 100-seed weight. Among different traits, grain yield had high variation both at genotypic and phenotypic level due to the differences of genetic materials and also the differences of the environment. Grain yield was found to be positively and significantly correlated with plant height, pods/plant, 100-seed weight at genotypic and phenotypic levels.Keywords : Lentil, genetic diversity and PCA

Abstract

This study was conducted to evaluate root exudates from sub-Saharan indigenous weed species to induce germination of Strigahermonthica(Del.) Beth., a root parasitic weed.Significant variation in Striga seed germination was observed, ranging from an absence to the induction of 74.1% Striga seeds. Direct comparison of Striga germination was obscured by differences in weed root biomass as within most of the species, a direct proportional relation between Striga seed germination and weed root dry weight was observed. Expression of Striga seed germination in % g-1root dry weight (GIC) was found a suitable solution, as stable values for GIC were obtained, despite considerable variation in root dry weight. GIC was significant for 25 species and highest with Commelinaforskalaeiand Sesamumalatum(9.91; 9.78 % g-1 dry root, respectively). Striga seeds did not germinate following application of exudates from Mitracarpusscaberand Phyllanthuspentrandus. These results show that a substantial number of indigenous weed species may serve as alternative trap crops to control the parasites seed bank. Furthermore, the timing of weeds in the cropping system may provide a (partial) explanation for the erratic infestation levels found across fields and years that has dazedresearchers for many years.

Abstract

The research was aimed to obtain the optimum concentration of BAP to buds growth as in vitro. It was conducted in the Tissue Culture Laboratory at Forestry and gardening seedling Unit of Forestry and Gardening Office of Banten Province from April until December 2008. The research used Randomized Completely Design on MS base medium with different BAP concentration: (1) B1 = MS + Kinetin 0.1 ppm + BAP 1 ppm, (2), B2 = MS + Kinetin 0,1 ppm + BAP 2 ppm, (3) B3 = MS + Kinetin 0,1 ppm + BAP 3 ppm, (4) B4 = MS + Kinetin 0,1 ppm + BAP 4 ppm, (5) B5 = MS + Kinetin 0,1 ppm + BAP 5 ppm. Each treatment was replicated ten times. The data was analyzed and continued with Duncan Multiple Range Test (DMRT) 5 percent. The explant which grew in MS media with different BAP concentration showed radicle appearance. It tended to grow to be embryo, where it began with radicle length and was followed by bud formation. Higher BAP application for each treatment increased the germination. The best concentration of embryo germination which would be grown to be bud was 4 or 5 ppm BAP.

Abstract

Populations of F1, F2 and BC1F1 were formed from an interspecific cross between green-flowered Jatropha curcas and red-flowered J. integerrima (dwarf type) to observe for segregation in flower colors and to select for ornamental segregants. The crossing to produce F1 and BC1F1 was successful only when J. curcas was used as the female parent. The suitable time for crossing was between 08:00 – 13:00 o’clock with fruit setting rate of 65-78%. The F1 segregated into white- and pink-flowered plants. While flowers of the F2 population segregated into nine different colors, viz. light green, green, white, very light pink, light pink, pink, deep pink, very deep pink, and red. When J. curcas was backcrossed by a pink-flowered F1, its BC1F1 progenies segregated into green, light green, white, very light pink and light pink flowers. While another set of BC1F1 progenies obtained from a white-flowered F1 parent segregated into green, light green, and white. The segregating progenies in both sets showed smaller plants than jatropha and bore colorful flowers suitable for ornamental purpose. Six plants were chosen and registered at Kasetsart University and the Thai Department of Agriculture as commercial cultivars, ‘Kamphaeng Saen 1’ to ‘Kamphaeng Saen 6’. Keywords: ornamental jatropha, interspecific cross, flower color, crossing durations

Abstract

The role of N, P and K on temulawak have not been clear enough to explain the need  in  temulawak  rhizome in order to get high yield. The experiment was conducted in a screen house in  Malang East Java with an altitude of 500 m asl. from Desember 2010 - August 2011. There were 4 experiments in series, consisting of N, P, K various level and N,K alone and combination on the growth and  quantity  of rhizome arranged in  randomized block design comprising 7 levels of fertilizer per plant with 3 replications. The treatments of urea (N), SP36 (P) consisted of 0, 1,25, 2,5, 3,75, 5, 6,25 and 7.5 g. The KCl (K) comprised 0, 1,5, 3, 4,5, 6, 7,5 and 9 g. The N, K alone and combination treatments consisted of (No fertilizer, N, K, NK g /plant). The results of this research were N, P, K optimum dose of each N 6.25 g N / plant P2O5/tan P 6.25 g, K 7.5 g K2O / plant increased temulawak rhizome dry weight. Combination 4.5 g N + 2.8 g K / plant could increase temulawak rhizome dry weight by 33% compared to the addition of N and 220% when compared to the addition of a single K harvesting age 6 months.

Abstract

The adaptation trial was applied to determine the benefits of genotype-environmental interaction, adaptability and stability of lines. The previous research successfully obtained 8 UB lines which had high yield and tolerant to aphids. These lines belong to plant breeding laboratory of Brawijaya University, which had stability and a high potential can be immediately released to the public. Research was conducted in 2010, dry and rainy season, on 3 locations of yardlong bean, namely Malang, Kediri and Jombang. Randomized Block Design was applied in these locations.Genotype-environment interaction was analyzed with combined analysis of nested design.The adaptability and stability were known from regression analysis based on the stability of Eberhart and Russel. There were 6 stabile lines, namely UB7070P1, UB24089X1, UB606572, UB61318, UB7023J44, and UB715, respectively. They were recommended to be released as new varieties which had pest tolerance and high yield. The UBPU was suitable to be developed in marginal land. The 6 new varieties had registered to Agriculture Department Republic of Indonesia, namely, Brawijaya 1, Brawijaya 3, Brawijaya 4, Bagong 2, Bagong 3 dan Bagong Ungu, respectively.
