Abstract

The use of nitrogen chemical fertilizers tends to be high in soils with low nitrogen; this can affect the balance of the global N cycle. One alternative to minimize the above problem is to optimize the utilization of biological nitrogen fixation. The purpose of this study was to determine the effect of increased nitrogen uptake of yields and some soybean varieties. The study was conducted using a split plot design that consisted of three factors where the first factor was Rhizobium (R) inoculation, the second factor was soybean (V) variety, and the third factor was N (N) fertilizer. Results of this study showed that the N fertilization treatment gave a significant response while Rhizobium (R) treatment and variety (V) did not provide a significant response to the harvest index parameters. The interaction of varieties and N fertilization (VxN) gave a significant response while the interaction of Rhizobium and varieties (RxV), Rhizobium and N (RxN), Rhizobium fertilization, varieties and N (RxVxN) fertilization did not provide a significant response to the harvest index. The highest Index was Wilis variety that was harvested without N (V3N0) fertilization but was not significantly different from V3N1, V3N2 and V3N3. The production of soybean seeds had not been able to increase ESN because the plant dry weight and N uptake were not comparable.

Abstract

There are still many farmers in Indonesia who use a single fertilizer such as N, P, or K fertilizer. While the needs of plant nutrients are not only that nutrients but also other macronutrients. One of single fertilizer used is KCl fertilizer which only contains essential K nutrients and micro Cl nutrient elements. To overcome this problem, another source of K fertilizer that does not contain Cl is used, especially in Pamelo citrus nurseries. POLY4 fertilizer is used as a source of K nutrients, because it has an excess of containing several nutrients such as K (14%), Ca (17%), Mg (6%), and S (19%). This research was conducted at the BALITJESTRO screen house and the Soil Department Laboratory, Faculty of Agriculture, Brawijaya University. The research design used was a completely randomized design with 5 treatments i.e P0 (100% MOP), P1 (50% POLY4 + 50% MOP), P2 (100% POLY4), P3 (150% POLY4), and P4 (200% POLY4). Parameters of this research were plant height, numbers of leaf, soil pH and exchangeable K, and K content in plant. Result of this study indicated that application of 50% POLY4 + 50% MOP (642 kg ha-1 POLY4 + 150 kg ha-1 MOP) significantly affected the height and number of leaves of Pamelo orange seedlings in 12 weeks, respectively 6.39% and 13.6 % compared to 100% MOP/control (300 kg ha-1 MOP). Application of 150% POLY4 (1,927 kg ha-1 POLY4) significantly increased plant K level by 9.40% compared to control (300 kg ha-1 MOP). Application of POLY4 fertilizer had no significant effect on pH and exchangeable K. The best dose of fertilizer in Pamelo citrus nurseries is the application of POLY4 642 kg ha-1 POLY4 + 150 kg ha-1 MOP (50% POLY4 + 50% MOP).

Abstract

Pesticide exposure in the soil is indicated to affect soil fertility as well as nutrient uptake by the plant due to its active ingredient that can affect soil sorption. This research focused on organic matter effect on soil fertility (pH, organic-C, N, P, K) in the soil under several doses of pesticide exposure as well as nutrients (N, P, K) uptake by the green mustard plant. Treatments consisted of control, d and four doses of pesticide application (50%, 100%, 150%, 200% of recommendation dose), four doses of pesticide application combined with two doses of manure application (0 and 2 t ha-1). Soil pH, organic C, N, P, and K were measured before treatments and after harvest. Nutrients uptake (N, P, K) and yield of green mustard were measured at harvest.  Results of the study showed that the exposure of pesticide in soil reduced the yield of green mustard by 40% compared to control. Nutrients (N, P, K) uptake by plant decreased by 72%, 92%, dan 78% compared to control in soil with exposure of 0,2 ml pesticide 500 ml-1 water even though with the addition of organic matter.

Abstract

Nitrogen is a macro nutrient need by plants to enhance growth and productivity. Nitrogen element can be supplied through inorganic fertilizer, compost or biological fertilizer. The purpose of this study was to analyze the effect of vinasse compost and endophyte bacteria of Klebsiella sp. on nitrogen uptake and sugarcane growth. The treatments tested in this study were K0 = control (no compost vinasse and Klebsiella sp.), P1 = (Klebsiella sp. + 75% ZA + 25% vinasse compost), P2 (Klebsiella sp. + 50% ZA + 50% vinasse compost), P3 (Klebsiella sp. + 100% ZA fertilizer + 0% vinasse compost), P4 (without inoculation of Klebsiella sp. + 75% ZA + 25% vinasse compost), P5 (without inoculation of Klebsiella sp. + 50% ZA + 50% Vinasse compost). The treatments were arranged in a completely randomized design with five replicates. The results showed that endophyte bacteria could only enter in P1 treatment. The total N-content, N-available and N-absorption were associated with P1 treatment. Vegetative growth of sugarcane did not show significant different. The P1 treatment had the highest value of plant height and number of leaves. As for the number of tillers, on 4 terms, the highest value was observed on P2 treatment.

Abstract

This study was aimed to elucidate the level of degree of mycorrhiza infection with some way of land preparation and weed management in Deli Serdang, Karo and Simalungun Regencies of North Sumatera Province. The percentage of degrees of mycorrhiza infection in maize roots was observed in the laboratory at the end of the vegetative period using a magnification microscope of 100 times. It was carried out by choosing a fine root (root hair) from a representative of various sides of the roots with a diameter of between 0.2 and 2 mm, washed with clean running water then put the root into 10% KOH solution and left for 24 hours. Results of the study indicated that the best treatment of soil treatment and weed control was 32.67% in T3 treatment (OTS 21 and 42 HST weeded) and the lowest was 11.00% in T6 treatment (TOT 21 and 42 HST paraquat application) and had a significant effect on Karo Regency with the best value of 31.33% T1 (OTS 21 and 42 HST paraquat applications) and the lowest value of 10.00% in T10 treatment (TOT and no controlled weeds). Soil treatment with twice weedings caused the highest degree of mycorrhiza infection in Deli Serdang Regency, while soil treatment with twice application of paraquat resulted in the highest degree of mycorrhiza infection in Karo Regency.

Abstract

Environmentally friendly and conventional cultivation systems that are selected and used by farmers can directly or indirectly affect microbes in the soil. Microbial population diversity can be used as a sensitive parameter to soil quality. Bacterial populations are a determining factor in ecosystems that are important because of biological and biogeochemical cycles, and heterotrophic activities. This study suggests looking at environmentally friendly (O1) and conventional (K1, K2, K3) soil bacteria on soil planted with sweet maize and function of bacteria in ecosystems. The results of this study that diversity on environmentally friendly was higher than conventional soil. The value was 1,775; while those of the conventional lands 1, 2 and 3 were 1,587; 1,245 and 1,320. In O1 soil, the most common genus was Agrobacterium and bacteria which were only found in environmentally friendly soils were Bacillus and Clostridium. Bacteria found such as O1F and O1G which were related to B. paramycoides could be used as biological agents against Cercospora leaf spot disease, B. megaterium could bind nitrate to the rhizosphere and dissolve phosphate in the soil, and B. aryabhattai which was potential as biological fertilizers and bioremediation

Abstract

The Inceptisol of Karangploso Malang has low pH (5.33) and low C-organic content (1.39%). Efforts can be made to improve these problems through land management with the use of organic fertilizer. Bokashi is one of the composts produced from fermentation process with EM4 which can improve soil chemical properties, because bokashi has elements of N, P, K, Na, Ca, and Mg respectively 1.22%, 0.53%, 1.71%, 5.64%, 0.62% and 2.01%. This study was carried out at the Greenhouse and Chemical Laboratory of Soil Science Department, Agriculture Faculty, Brawijaya University. The design of this research was a completely randomized design with O0 treatment (control); O1 (Bokashi 5 t ha-1); O2 (Bokashi 10 t ha-1); O3 (Bokashi 15 t ha-1); O4 (Bokashi 20 t ha-1); O5 (Bokashi 25 t ha-1); O6 (Bokashi 30 t ha-1) which was repeated 3 times. Parameters measured were pH, CEC, BS, K-exch, Na-exch, Ca-exch, and Mg-exch on 1 MAI (month after incubation), and 2 MAI. The results showed that  increasing the dose of bokashi application at 1 MAI significantly increased K-exch and Mg-exch compared to the control treatment, but did not significantly affect pH, CEC, BS, Na-exch, and Ca-exch. Furthermore, increasing the dose of bokashi application on 2 MAI significantly increased pH and K-exch compared to the control treatment, but did not significantly affect CEC, BS, Na-exch, Ca-exch, and Mg-exch.

Abstract

Verification of oil palm plants is done to cross check with census data on the number of plants to find out the number of oil palm plants in each. Unfortunately the company still has difficulty detecting the amount of palm oil in each block. One effort to overcome this problem is to use GIS (Geographic Information System). The purpose of this study was to determine the effect and differences in the use of photogrammetric methods with the waypoint method, the role of GIS (Geographic Information System) and determine the number of oil palm trees to be planted in the blocks in Afdeling I and Afdeling IV. This research through the preparation stage by preparing a sub-block map and flight plan, data collection stage by collecting aerial photo data, waypoint, block SHP, information on block area, planting year information and initial basic information on oil palm, the data processing stage using the mosaicking approach on the Agisoft PhotoScan Propessional application, waypoint conversion with Global Mapper and overlaying aerial photos with a waypoint with ArcMap 10.3. The results showed that the waypoint using GPS had higher accuracy compared to aerial photography and had an effect on the overlay results at the planned waypoint distance with the initial principal palm oil object. GIS is useful for processing aerial photo data and waypoints from GPS, and can speed up side verification. The plan is to insert in the B37 Block as many as 462 principal, B38 Block as many as 928 principal, B39 Block as many as 1,611 principal, B40 Block 351 principal, Block D29 1,063 principal, D30 Block 1,085, A53a Block 2,665 principal, A55a Block 539 subjects , C55 Block as many as 371, C56 Block as many as 510 principal, D55 Block as many as 157 principal, D56 Block as many as 375 principal, D57 Block as many as 1,561 and Block D59 with 1,431.

Abstract

The national production of garlic that is currently under fluctuations and could not fullfill demand for garlic that led Governments to perform the import. Land extensification for garlic in East Java, Pujon district, Malang is expected to be the solution to increase production. However, restricted by the limitations of the information of land characteristics that remains unclear, it takes effort to find out the land characteristics for garlic in the subdistrict of Pujon. Research was carried out for gathering information of land characteristic and to analyze relationships between land characteristics and garlic production. This study was carried out using survey method include groundcheck, minipit observation, soil sampling, and interviews to the farmers. Then, post survey analysis activities include laboratory analysis, soil classification, and statistical data analysis to test the correlation between land characteristics with garlic production. Results of the research showed that land of garlic in Pujon District has Inceptisols and Alfisols. The land characteristics in Pujon district has difference, among others, land elevation are 861–1.213 mdpl, slope of land are 3–36%, soil texture are “loam” to “clay “, soil aggregate are “very-stable”, soil pH ranging from very acid to semi acid, soil CEC are “moderate” to “very-high”, and the base saturation are “low” to “very-high”. The relationship between land characteristics to crop production, proved by correlation between variable such as elevation (r =-0.559), CEC (r =-0.515), base saturation (r = 0.561), % sand fraction (r = 0.541), and % clay fraction (r = -0.675). Other factors affecting garlic production are varieties of garlics and soil tillage, these correlation are not significant.
