Abstract

The objectives of the experiment were to evaluate effectiveness of seed treatments to eliminate Cmm of infected tomato seed lot, evaluate physiological quality of Cmm infected tomato seed lot after treatments with plant extracts. The research used curcuma rhizomes, betel vine leaf extract, cinnamon and clove oil to eliminate Cmm in tomato seed. Part of the seeds were dipped in either suspension of curcuma rhizomes, betel vine leaf extract, cinnamon and clove oil for 20 minutes and the others were matriconditioned using a mixture of burned rice hull (at 22 0C and RH 60-70%) plus either of plant extracts or oils. Elimination of Cmm from infected seeds was observed 10 days after treatments, and physiological seed qualities were evaluated before and after seed treatments. Results of the experiment indicated, dipping infected seeds in either 5% of curcuma, betel vine extract, cinnamon oil or 0.5% of clove oil suspension or matriconditioning plus either these extracts, eliminated 99% of infected Cmm on tomato seeds. Seed treatments using plant extracts for elimination of Cmm did not reduce seed germination, germination rate, vigor index, and did not increase time to reach 50% total germination (T50) of infected tomato seed except the seed treatment by using 5% cinnamon oil with or without matriconditioning.Key words: plant extracts, physiological quality, seed viability, vigor

Abstract

The objective of this research were analyzed the suitability of Horton and Philips infiltration models in various land use in upper Progo sub watersheds. Infiltration rate was measured in the field used inundation method by double ring infiltrometer. This research also needed soil physic data, shape and land use area of upper Progo sub watersheds. Models were tested by comparing measurement infiltration rate and infiltration rate of the model, were tested statistically using correlation coefficient (R), deterministic coefficient (R2), and paired test (T test). The test results showed that Tcounted value were smaller than Ttable for both Horton and Philips infiltration model at various types of land use, but R and R2 value of Philips infiltration model higher than Horton. Conclusion of this research, that both Philips and Horton infiltration models were still quite suitable for determination infiltration rate in upper Progo sub watersheds. Philips infiltration model was better because simpler, constants more easily searchable, and not too influenced by subjectivity.Keywords : infiltration models, land use, suitability analysis, watersheds

Abstract

The research was aimed to know production potency of five New Superior Varieties of Rice Plant (Oryza sativa) of Stock Seed that was grown in Banjar District Pandeglang Regency of Banten Province. Research was conducted in the village of Kadu Bale, Banjar District Pandeglang Regency in May until August 2011. The research used a Randomized Completely Block Design with five new superior varieties as factor that consisted of five levels with five replications. Parameter observed were: 1) the percentage of replace with new rice seedling, 2) the number of maximum tillers, 3) the percentage of non productive tiller, 4) age of panicle appear, 5) number of panicle, 6) the percentage of green panicle more than 80 % , 7) number of grain each longest panicle, 8) percentage of empty grain each panicle, 9) weight of 100 full grain, 10) ratio of long and weight full grain, 11) production of dry harvest grain , and 12) productivity of dry harvest grain per hectare. The result showed that qualitative observed of the six varieties still suitable with the their description. The quantitative observed was influenced by physical condition naturally and cultivation. For positive effect were showed by the parameter observed : 1) the percentage of replace with new rice seedling, 2) the number of maximum tillers, 3) number of panicle, 4) weight of 100 full grain, but for negative effect were showed by the parameter observed: 1) the percentage of green panicle, more than 80 % , 2) number of grain each longest panicle, 3) percentage of empty grain each panicle, and 4) production of dry harvest grain. For cultivation action gave the best physiology effect only to Ciherang. The percentage of green panicle more than 80 % was 6,39 % fewer than another varieties (inpari 1, Inpari 7, Inpari 8, and Inpari 13).Key words: rice, stock seed, new superior varieties, potential production.

Abstract

The experimen was done to know the best combination of the treatment with the used of different types of explan conducted in Tissue Culture Laboratory, 633 Biotechnology Building - Center for the Assessment and Application of Biotechnology (Biotech Center of BPPT), Agency For The Assesment and Application of Technology (PUSPIPTEK), Serpong July to October 2009. The results of this study is expected to be used as a reference in the process of guava rapid regeneration (in vitro) in order to support quality improvement activities of the guava plant. Research used Completely Randomized Designed (RAL) with 3 factors, BAP concentrations level (0; 2.5; 5; 7.5 and 10 mg/L), IBA concentrations level (0 and 0.5 mg/L) and types of explan (cotyledon, hipokotil and tip). Results showed that combination treatment of 0 mg/L BAP and 0.5 mg/L IBA was good for callus initiation hipokotil and cotyledon at 2 weeks after palnting, diameter of callus in the cotyledon and the number of roots. Treatments combination which most effective in inducing shoot growth is the tip treatment with the concentration of 10 mg/L BAP and 0.5 mg/L IBA in 6 weeks after planting. Concentration of 2.5 mg/L BAP and 0.5 mg/L IBA is a combination of the best growth regulator substances to the shoot height, number of leaves and node. Provision of BAP, IBA and Explan either single or interaction between the second and third generally provide a significant effect on the growth of Psidium guajava L.Key words: guava plant, Psidium guajava L., BAP, IBA

Abstract

The experiments were conducted to determine soybean growth and yield responses to various ways of placement and dose of urea fertilizer. Experiments using a randomized block design factorial, with four replications. The first factor is the ways of placement of urea consists of two levels, namely: be placed next to the planting hole and placed along the bolt in between the rows of plants. The second factor is the dose of urea fertilizer consists of four levels, namely: 50 kg ha-1, 100 kg ha-1, 150 kg ha-1, and 200 kg ha-1. The results showed that the growth of soybean (plant height and number of leaves) showed no differences due to different ways of placement urea but soybean yield components and the yield showed differences due to different ways of placement of urea. Yield components (pod number, pod dry weight, and number of seeds) and yield (seed dry weight) of soybean is higher when the ways of placement of urea along the bolt is placed in between rows of plants compared with plants placed on the side. Differences urea dose given either 50 kg ha-1, 100 kg ha-1, 150 kg ha-1, and 200 kg ha-1 showed no difference on the growth and yield of soybean plants.Key words: doses, fertilizers placement, soybean, urea

Abstract

The research aimed to know the influence of competition with weeds K fertilizer on the growth and yield of green bean plant, has been held in the shadow home Crop Science Study Program Graduate of Sriwijaya University, from September to December 2010. The designs used in this study were factorial randomized block design with three replications. The first factor is rhizome reeds: R1 = 0, R2 = 2, R3 = 4, R4 = 6, R5 = 8 rhizome polybag-1. Factor II doses of fertilizer K, K1 and K2 = 0 g = 1.25 g KCl polybag-1. The results showed that the growth and yield of green beans decreased with the increasing number rhizome weeds that compete, either with or without fertilizer K fertilizer K. But with the growth and yield of K fertilization gives better results than without fertilizer K.Key words: competition, weed, fertilizer K, green beans

Abstract

Rhizobacteria was a colonialist bacterial at rooting area that had capacity to produce IAA and enhance plant growth. Rhizobacteria indigenus chili had ability to produce IAA and induces various of plant growth. IAA production was not always linked with the ability to enhance plant growth.
