Abstract

Land circumstances on Seputih Mataram, Lampung included in dried area which is consist of Ultisols soil (soil taxonomy). Ultisol consist of H2O which has pH of less than 5.5. It will cause the amount of soil nutrient that absorbed is not optimal yet. This research aimed to know the influence of adding dolomite to the soil chemical content (pH number of H2O, KCl, content of total N, available P, exch-K, exch-Ca, exch-Mg, Organic-C, ratio C/N, exch-Al, exch-H, CEC), nutrient content on the leaf (such as N, P, K, Ca, Mg) and sugar cane physic. This research used Completely Randomized Design 2 factors with 3 blocks repetition. First factor was the dolomite doses in six contents: without the dolomite (K0), 500 kg/ha (K1), 1000 kg/ha (K2), 2000 kg/ha (K3), 4000 kg/ha (K4) and 6000 kg/ha (K5). The second factor (R) was the depth of dolomite placement, consist of: (R1) dolomite with 0-20 cm depth and (R2) dolomite with 20-40 cm depth. The observation used to know the soil chemical content, the leaf nutrients and the variables that used into the research. The observation results variant analyzed (ANOVA) in 5 % and continued with the Duncan’s Multiple Range Test (DMRT) in 5 % if the result showed the real differentiation. The result showed that the depth of dolomite was not real influence to the amount of Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), and Magnesium (Mg) in leaf. Dolomite addition was real influence for Calcium (Ca) uptake in leaf, but it was not real influenced the leaf uptake. Dolomite addition was real influence in the leaf content and leaf Magnesium (Mg) uptake. 6000 kg/ha dolomite for physical soil characteristic ( pH H2O, pH KCL, C/N ratio, K, P, Ca, Mg,Exch-H), leaf nutrient ( N, K, Ca), Mg and Ca uptake on leaf also sugar cane tonnage per hectare showed the maximum result.

Abstract

An approach to minimize the loss of nitrogen (N) evaporating from urea is by inhibiting urease activity by urea coating with N- (n-butyl) thiophosphoric triamide (NBPT) and N- (n-propyl) thiophosphoric triamide (NPPT). The effect of urease inhibitor to minimize N loss has not been done in inceptisol soil. The purpose of this study was to study the effect of urease inhibitor coated urea on growth, physiological activity and yield of maize in Inceptisol Jogonalan, Klaten, Indonesia. The treatment was laid out in a Randomized Complete Block Design with 4 replications namely N0 (without fertilizer), N1 (urea + NBPT 348 kg ha-1) and N2 (urea + NBPT 278 kg ha-1). All treated plants was fertilized once in one growing season 3 weeks after planting (WAP). Observations were done on several variables: soil physicochemical characteristics, plant physiological activity as well as growth and yield of maize. Data were analyzed using Analysis of Variance (ANOVA), and then the mean comparisons were done by using Least Significance Difference (LSD) test at 5%. The results showed that fertilization affected all observed variables. The effect of urea-coated urea inhibitor urease (NBPT+NPPT) compared with N0 (control) showed very optimum result, especially in N2 treatment. The urea coated with NBPT + NPPT (urease inhibitors) was more effective at lower dose of 278 kg ha-1 and tended to provide better results indicated by the growth and yield of maize in Inceptisol, Jogonalan, Klaten. The better growth as well as the higher yield of maize that was indicated by seed weight of 11,45 tons ha-1 and 100-seed weight of 37.75 g were obtained from N2 treatment as compared to other treatments. The hybrid maize (P35) has an optimum yield potential of 12.1 tons of dry pipes per hectare.

Abstract

Post-harvest handling in shallot such as drying of bulbs can influence its quality during and after storage. The objective of this study was to determine the impact of drying and storage treatment on the quality of shallot bulbs during 12 weeks of storage . The study was carried out in Samiran hamlet, Parangtritis village, Bantul district, Special Region of Yogyakarta and Crop Science Laboratory of the Faculty of Agriculture, Universitas Gadjah Mada, from June until November 2016. It was arranged in factorial randomized complete block design (RCBD) and consisted of two factors. The first was the drying treatments: drying the bulbs on the field and on woven bamboo nets both plastic covered and uncovered. The second was the storage treatments: storing the bulbs in the farmer’s warehouse (31,030C±0,04 and RH of 60,50%±0,28), in air-conditioned room (22,40oC± 0,02 and RH of 61,60%±0,09), and at room temperature (30,47oC±0,03 and RH of 60,50%±0,12). Each treatment combination was replicated three times as blocks. The results showed that water content of all treatments were changing followed by fluctuating of the total soluble solid throughout the storage period while bulb firmness tended to decrease. Bulbs which were stored in air-conditioned rooms showed the highest percentage of sprouted bulbs, vigor index and germination rate than other treatments. Meanwhile, drying treatment did not give significant influence.

Abstract

Telomere has special roles at the ends of eukaryotic chromosomes that consisting of repeated DNA sequences. It protects chromosomes and DNA from damage. The plant sex and the leaf development may change in telomere length. Snake fruit (Salacca zalacca GART. VOSS.) is dioecious plants that have female and male organs on separate plants. The aim of this research is to determine the telomere length of snake fruit from different plant sex and the leaf development. In this research, we observed telomere length in snake fruit (female and male plants) using Polymerase Chain Reaction (PCR) procedure. The results from this study showed that telomere lengths of male and female are equal. Telomere lengths in the leaf development showed that younger leaves of both male and female leaves are longer compared to older and dried leaves.

Abstract

Nitrogen (N) fertilizer efficiency can increase by adding N-(n-butyl) thiophosphoric triamide (NBPT) and N-(n-propyl) thiophosphoric triamide (NPPT) as urease inhibitor in urea fertilizer and adding 3,4-dimethyl pyrazole phosphate (DMPP) as nitrification inhibitor in ammonium sulfate (ZA) fertilizer. The research objectives were to examine the effectiveness of urease inhibitor (NBPT and NPPT) and nitrification inhibitor (DMPP) on the physiological activity and oil palm yield on red-yellow podzolic. Field experiment was done using a Randomized Complete Block Design (RCBD) of single factor and three replications as block. The single factor was nine fertilization treatments of urea with or without urease inhibitor, and ZA with or without nitrification inhibitor. The use of urease inhibitors decreases the amount of volatilization and N loss fertilizer. The higher dose of broadcasting N fertilizer (on the same type of fertilizer) resulted in the higher amount of N loss and volatilization. All fertilization treatments did not have any significant influence to the width and the length of opening stomata, nitrate reductase activity (NRA), N concentration in oil palm leaf, Oil Extraction Rate (OER), and Free Fatty Acid (FFA). Meanwhile, The oil palms at yellow red podzolic applied with urea 195 kg/ha combined with 0.12% of NBPT-NPPT resulting in higher fresh fruit bunch productivity.

Abstract

Increased productivity of rice is required to meet the increasing food demand. Utilization of marginal lands, such as saline land is one of the solutions applicable to increase rice production. The objective of this study was to determine the growth and yield of Inpari 29 rice variety planted on raised-bed and different depths of sunken-bed in saline field. This study used the Split Plot Design with two treatments. The depth as the main plot consisted of two depth levels: a depth of 50 cm and a depth of 25; and the planting area field as the subplot that consisted of two levels: raised-bed and sunken-bed. The treatment was repeated three times. The rice planted in sunken-bed showed higher growth than in raised-bed as indicated by the high content of chlorophyll a, chlorophyll b, total chlorophyll, nitrate reductase activity and plant height. The rice planted in the sunken-bed yielded higher than in raised-bed as indicated by higher harvest index and the weight of grain per clump. Rice planted in 25 cm depth showed higher nitrate reductase activity and grain weight per clump than in 50 cm depth.
