The correlation test between P uptake by plant and determination method of available P is the initial stage in the establishment of fertilizer recommendations. This study aimed to examine various extraction methods of available P in the soil and determine the appropriate P extraction method for dry acid soil (Inceptisol) used to cultivate chili crop. The study was conducted at the screen house of Indonesian Vegetable Research Institute, West Java, Indonesia from January to December 2015. A randomized block design with five treatments and five replications was set up for this experiment. The treatment of status of soil P was obtained by administering SP-36 at various doses, namely: 0X, Â¼X, Â½X, Â¾X, and 1X, where X = 250 kg SP-36 ha-1. To obtain the desired P nutrient status, the Inceptisol soil that has been added with SP-36 fertilizer with different doses was incubated for four months. The chili seedlings were then planted on each of those soils, and the analysis of P absorption was carried out at the age of 60 days after planting. There were six extraction methods used to analyze available P in the soil, i.e. HCl 25%, Bray I, Bray II, Mechlich, Truog, and Morgan Vanema. The results showed the different response of crop on P uptake to the level of soil P nutrient status. Plant P uptake increased with the increase in soil P nutrient status. The best P extraction methods for Inceptisols for chili cultivation were HCl 25% and Mechlich with correlation coefficient values reached 0.7802 and 0.7351, respectively.

Maize (Zea mays) is one of the major crops and widely grown in Indonesia. On average, current maize yields are still below its potential. Thus, it needs to increase by good agricultural practices such as applying biofertilizer, which consists of beneficial bacteria. This research was aimed to find out the impact of the bacterial consortium of nitrogen-fixing bacteria (BPN) and phosphate solubilizing bacteria (BPF) on the maize growth. The study was conducted in the greenhouse and arranged in a completely randomized design (CRD) with treatments, i.e.: (1) negative control (no inorganic fertilizer and BPN-BPF); (2) positive control (100% inorganic fertilizer); (3) only BPN-BPF applied (no inorganic fertilizer); (4) 75% inorganic fertilizer + BPN-BPF; and (5) 50% inorganic fertilizer + BPN-BPF. The results revealed that the consortium of nitrogen-fixing bacteria and phosphate solubilizing bacteria significantly improved certain soil chemical properties, such as C-organic, cation exchange capacity (CEC), and the availability of nitrogen and phosphorus in the soil. Besides, the consortium of BPN and BPF also increased the maize growth and total biomass up to 19%. Further, a consortium of BPN and BPF increased the fertilizer efficiency by reducing the dosage of inorganic fertilizer up to 50%.

Liming increases soil fertility through improved soil conditions in acidic soils (Ultisols). This study aimed to determine the effect of limes [CaO; Ca(OH)2; CaCO3 and CaMg(CO3)2 ] on the chemical properties of Ultisols of Limau Manis Padang. Treatments tested in this study application of four types of lime, i.e. A = CaO; B = Ca(OH)2; C = CaCO3; dan D = CaMg(CO3)2. on an Ultisol. A control treatment with no application of lime was also included in this study. After incubation of the soil-lime mixtures for two weeks, the results of the study showed that liming using dolomite [CaMg(CO3)2] was more effective in improving the chemical properties of Ultisols, compared to other types of lime [CaO; Ca(OH)2; CaCO3]. The effect of dolomite on 1*exchangeable Al (1 me Ca 100 g-1) improved chemical properties of an Ultisol from Limau Manis Padang such as pH H2O by 0.35 unit, available P by 1.03 ppm, exchangeable Al by 0.91 cmolc kg-1; exchangeable H by 0.92 cmolc kg-1; CEC by10.49 cmolc kg-1; exchangeable K by 0.03 cmolc kg-1; exchangeable Ca by 0.44 cmolc kg-1 and exchangeable Mg by 1.34 cmol ckg-1, compared to control.

One of the heavy metals that most contaminates the environment and soil is copper (Cu) that mostly comes from the activities of electroplating industries. This study aimed to identify the ability of Boehmeria nivea in absorbing Cu absorption from planting medium containing Cu. The Boehmeria nivea plant was grown on soil contaminated with six CuSO4 concentration levels, i.e.Â 0 ppm Cu (P0), 10 ppm Cu (P1), 20 ppm Cu (P2), 30 ppm Cu (P3), 40 ppm Cu (P4), and 50 ppm Cu (P5). The results showed that Boehmeria nivea plant could absorb Cu and survive in the Cu levels of 25 â€“ 125 ppm in the soil. The Bioremediation Index indicated that Boehmeria nivea could reduce copper in the soil up to more than 50%. The mechanism of phytoremediation was categorized into phytostabilization, since the result of all treatments showed the value of translocation factor (TF) of less than 1. The presence of Cu in the soil affected plant height and leaf number of the plant Boehmeria nivea. However, on the actual condition, Boehmeria nivea did not show any symptom of Cu toxicity

Chlorophyll in leaves affects the reflection of infrared light, where healthy plants can reflect more infrared light than unhealthy plants which is one of the factors increasing production in coffee plants. Normalized Difference Vegetation Index (NDVI) is a plant index that utilizes red and infrared light. Therefore, in this study, the algorithm used to determine the chlorophyll content is NDVI. The purpose of this study was to assess the value of chlorophyll content, the value of vegetation index, and to estimate chlorophyll content in coffee plants in PTPN XII Bangelan Village using a remote sensing method. The results showed that the average chlorophyll content of coffee plants assessed using the SPAD (Soil Plant Analysis Development) aid was 65.95 mg g-1. The average Vegetable Index of coffee plants was 0.59. NDVI vegetation index was directly proportional to the value of chlorophyll content in the leaves of coffee plants with the formula of y = 97.665x + 7.684 with R = 0.7153 where the x value is the NDVI value. Thus, remote sensing can be used to estimate the chlorophyll content of coffee plants.

Psament is a soil that has a low fertility rate which is characterized by low organic matter content (BO) so there are less water and nutrients available. Utilization of Psament for agricultural development must first be improved through other inputs such as BO and lime. This study aims to look at the interaction between KOJETO types and KOJETO doses on the chemical properties of Psament, to look at the effect of KOJETO types on the chemical properties of Psament, and to look at the effect of increasing KOJETO doses on the chemical properties of Psament. This research was conducted at the Wire House and Soil Laboratory of the Faculty of Agriculture, Andalas University, Padang. The experiment was designed according to a Factorial Randomized Complete Design with 2 factors and 3 replications. The main factor was the type of KOJETO which consisted of KOJETO A (0.75 PB Recommendations); KOJETO B (1 PB recommendation); KOJETO C (1.5 PB Recommendations). The second factor was KOJETO dose which consisted of (2.5, 5.0, 7.5, and 10.0) t ha-1. The results showed that the type of KOJETO with several doses interacted to increase the chemical properties of Psament with the highest value in the KOJETO C treatment with a dose of 10.0 t ha-1 namely N-total content of 0.34 %, CEC 15.87 cmol kg-1, Cadd 1,27 cmol kg-1 and Mgdd 0.69 cmol kg-1. The application of KOJETO C yielded the highest values of C-organic 2.80 %, Kdd 0.53 cmol kg-1 and Nadd 0.51 cmol kg-1. The single effect of increasing dose with the highest values at 10 t ha-1 were soil pH 5.80, P-available 14.59 ppm, C-organic 2.89 %, Kdd 0.52 cmol kg-1 and Nadd 0.50 cmol kg-1.

Rice field management affects the physical, chemical and biological characteristics of the soil, as well as crop productivity. Efforts are needed to maintain soil conditions by measuring the soil quality index. The purpose of this study was to determine the characteristics of the soil as a reference pattern of soil quality distribution. This research was conducted in July - November 2019 in Turen District, Malang, using a free survey method based on the Land Map Unit. Soil samples were taken at a depth of 0-20 cm at each observation (24 points) and analyzed in the laboratory. The soil quality index was calculated according to limiting factors and scores relative to 10 soil quality indicators. Soil quality classes are grouped into 5 classes, i.e. (i) very good (<20), (ii) good (20-25), (iii) moderate (25-30), (iv) bad (30-40) and (v) very bad (> 40). The results showed that the soil in irrigated and rainfed rice fields had different limiting factor values in the levels of available-P, total-N, soil organic-C and microbial biomass-C which caused differences in soil quality. Crop productivity on the land showed differences based on land suitability classes resulting in S1 and S2 classes

This study aimed to determine the effect of various types of solid (oil palm empty fruit bunches) and rice husk charcoal on the production of tomato plant (Solanum lycopersicum L). The treatments tested for this study consisted of two factors. The first factor was the provision of solid, i.e. S0 = without solid (control), S1 = 0.50 kg solid polybag-1, S2 = 0.70 kg solid polybag-1, and S3: 1 kg Â solid polybag-1. The second factor was the provision of rice husk charcoal, i.e. P0 = without husk charcoal (control), P1 = 0.2 kg husk charcoal polybag-1, and P2 = 0.4 kg husk charcoal polybag-1. Each polybag contained 5 kg of air-dried soil. The results of this study indicated that the provision of solid and rice husk charcoal against tomato plant production had no significant effect on stem diamater, total number of fruits per plant, and total weight of fruits per plant. However, the treatment interaction of 1 kg solid polybag-1 and 0.2 kg husk charcoal polybag-1 increased stem diameter, total number of fruits per plant, Â and total weight of fruits per plant.

The decline in lowland rice production can be caused by nitrogen nutrient loss through volatilization. The application of humic acid and Phonska 15-15-15 fertilizer can be a solution. This study aimed to determine the effect of humic acid and Phonska 15-15-15 fertilizer on nitrogen uptake by rice plant, rice plant growth, and nitrogen residues in paddy soils. The research used a randomized block design with 8 treatments and 3 replications. The treatments in this study included K (Control), A (Humic Acid 5 kg ha-1), P (Phonska fertilizer 240 kg ha-1), A1 (Humic Acid 1 kg ha-1 + Phonska 240 kg ha-1), A2 (Humic Acid 2 kg ha-1 + Phonska 240 kg ha-1), A3 (Humic Acid 3 kg ha-1 + Phonska 240 kg ha-1), A4 (Humic Acid 4 kg ha-1 + Phonska 240 kg ha-1), and A5 (Humic Acid 5 kg ha-1 + Phonska 240 kg ha-1). Â The parameters observed included nitrogen uptake in rice plants, rice plant growth, and nutrient residues in the soil. The results showed that humic acid and Phonska 15-15-15 fertilizer significantly affected N nutrient uptake, the highest effect was found in A3, which was 1.03 g plant-1 in 4 MST and 1.77 g plant-1 in 6 MST. Humic acid and NPK Phonska 15-15-15 fertilizer yielded the highest plant height at 4 MST and 6 MST was A3 treatment. The number of tillers at the age of 4 MST treatments gave the highest results, namely in the treatment of A3 and A4 as many as 3.33 tillers. At the age of 6 MST the treatment that gave the highest results was A3 treatment with 8 puppies. The nitrogen residues in the soil showed a significant effect where the highest residual yield in the soil was obtained from the A3 treatment of 0.23% as well as pH and C-organic respectively 6.69 and 3.10%.
