Abstract

This study aimed to determine the effect of arbuscular mycorrhizal fungi (AMF) and phosphate (P) fertilizer on the nutrient content, phosphate uptake and in vitro digestibility of alfalfa (Medicago sativa L.).The research was conducted at green house of Forage and Pastures Science Laboratory, Faculty of Animal Science Universitas Gadjah Mada. The experiment was arranged in Completely Randomized Design using 3x4 factorial patterns with four replications. The first factor was dosage of phosphate fertilizer SP 36 (0, 60, and 120 kg/ha). Second factor was the dosage of AMF (0, 0.8, 1.6, and 2.4kg/ha). The variable measured was nutrient contents (crude protein, dry matter, and organic matter), total P uptake and dry matter and organic matter in vitro digestibility. The results showed that the interaction of AMF and P fertilizer had no significant effect on crude protein and total P uptake, but highly significant effect on the parameters of dry matter, organic matter and dry matter and organic matter in vitro digestibility.

Abstract

Corn production can be increased by proper urea fertilizers. Fertilization techniques commonly used by farmers are broadcast or buried into soil. But in both of these techniques can make to lose urea faster, because nature of urea is easily changed to ammonium (NH4+), then changed to ammonia (NH3) which leads to volatilization or leaching. This study aims to compare urea fertilization techniques commonly used by farmers and their effects on the growth and yield of corn in Vertisol on rainy season. The research method used was a single factor in randomized complete block design (RCBD) with four blocks as replications. The treatments were without urea (N1), buried urea into soil (N2), and broadcast of urea (N3), with a urea dose of 348 kg/ha obtained from soil sampling analysis. The observation of parameters (1) Climatic condition, (2) physical and chemical characters of soil, (3) Plant height, (4) Effect N fertilization on root and shoot, (5) Chlorophyll content and nitrate reductase activity, (6) observations of harvested. The data were analyzed using Analysis of Variance (ANOVA) at 5% levels, and continued Duncan Multiple Range Test (DMRT) at test level of 5%. The results showed that fertilization affecteds all parameters. Buried into soil (N2) and broadcast (N3) technique was significantly different only in leaf N content that is 3,31% (N2), 2,16% (N3) and also in higher plant, but not significantly different in other variables. Based on this research, farmers still use broadcast techniques because they are more efficient in terms of time and energy.

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

The low yield of rice in thick peat can be overcome by provisioning complete nutrients. Various efforts have been made to increase the productivity of Indonesian peatlands, one of which is by adding salted fish waste and cow manure. This research was carried out on a plastic house scale from October 2017 to January 15, 2018, in Pelalawan District, Pelalawan Regency, Riau. This research was arranged in a Completely Randomized Design (CRD), consisting of eight treatments, namely L0 = Control, L1 = 1.5 ton.ha-1 of fish waste, L2 = 2.25 ton.ha-1 of fish waste, L3 = 7 tons/ha of cow manure, L4 = 15 ton.ha-1 of cow manure, L5 = 1.5 ton.ha-1 of fish waste + 7 ton.ha-1 of cow manure, L6 = 1.5 ton.ha-1 of fish waste + 15 ton.ha-1 of cow manure, L7 = 2. 25 ton.ha-1 of fish waste + 7 ton.ha-1 of cow manure, and L8 = 2.25 ton.ha-1 of fish waste + 15 ton.ha-1 of cow manure. The results showed that the application of cow manure and salted fish waste could increase soil pH, total NPK, and NPK uptake. The application of 2.25 tons/ha of fish waste and 15 tons/ha of cow manure resulted the best results in soil pH, total NPK, and NPK uptake, therefore it is recommended for the cultivation of lowland rice on peat soil.

Abstract

Shade trees are used in agroforestry pattern for production and service aspects. Cocoa-tree agroforestry pattern is expected to improve atmospheric and rhizosphere zone in cacao plantations. However, the information related to this is still quite limited. This study was conducted using a nested design, with types of shade trees as nest. Shade trees used were Falcataria moluccana, Cocos nucifera, and Cassia spectabilis, and without shade was used as control. Variables observed were light, air temperature, humidity, soil temperature, soil texture, bulk density, permeability, and moisture content. Soil chemical properties were also observed, including organic C, pH, total N, P, K, Ca, Mg, B and content of available P, K, Ca, Mg, and B. The results showed that cacao agroforestry pattern using F. moluccana and C. spectabilis was able to improve the microclimate characteristics and soil fertility. However, F. moluccana showed lower soil fertility than C. spectabilis. F. moluccana and C. spectabilis shade trees were able to optimize light plants from 33 % to 34 %, and from 38 % to 39 %, respectively. F. moluccana could provide optimal air and soil temperature of 30 ⁰C to 32 ⁰C and 27 ⁰C, respectively. Meanwhile, C. spectabilis could provide optimal air and soil temperature of 29 ⁰C to 31⁰C and  26 ⁰C to 27 ⁰C, consecutively. Cocoa-tree agroforestry pattern using C. Spectabilis shade trees could optimize soil moisture content, pH, total N, and P, and availabilities of K, Ca, Mg, and B in soil.

Abstract

Fermented complete feed (CF) based forage-fodder and agricultural by product as feed for ruminants can be implemented in the household and industrial purpose. Complete feed technology is one of alternative to solve the problems of stock and quality of feed. The nutritional value can be set by determine the number and type of mixture, livestock will not has an opportunity to choose so that it can minimize residual feed, practical, and can be stored for long periods. Fermented complete feed very much match to be implemented in the dry season or in the emergency situation. During Merapi Volcano eruption in 2010 was one of moment which is need CF technology. Rice straw can used for CF that can be socked during dry season, also the quality might improve (from 3—4% of crude protein content became 7—8%) with addition of rice brand or other ingredients. Fermented complete feed based on rice straw, forage-fodder or agricultural by product has a multifungtion in the emergency situation, reduce disaster risk, and feed security conservation.

Abstract

This study investigated the effectiveness of mycorrhizal fungal multi-spores and inorganic fertilizers in increasing NPK uptake and growth of maize on ombrogenous peat soils in Riau. The experiment, which was carried out in a plastic house, was arranged in a completely randomized design (CRD) with two factors, consisting of five replications. The first factor was the application of mycorrhizal fungal multi-spores, consisting of two levels (with and without application). The second factor was the application of inorganic fertilizer, consisting of three levels (P0: without fertilizer, PM-1: mixture of 225 kg Urea + 100 kg SP-36 + 75 kg KCl + 1000 kg Dolomite, and PM-2: mixture of 450 kg Urea + 200 kg SP-36 + 150 kg KCl +2000 kg Dolomite). Observed data consisted of agronomic observations, soil observations, and mycorrhiza observations. Agronomic observations consisted of plant height, root dry weight, shoot dry weight, and N, P, K nutrient uptake, and soil observations consisted of total and available N, P, K nutrients in the soil. Meanwhile, mycorrhiza observations consisted of infected roots and spore populations. The data obtained were then analyzed using DMRT to see the significant effect of the treatments. There was no interaction effect of mycorrhiza and compound fertilizer on the variables of shoot and root dry weight, but the interaction effect was observed on the variables of of shoot N, P, K uptake and root P and K uptake.
