This research had been conducted in the greenhouse and the Soil Laboratory of the Faculty of Agriculture, Andalas University, Padang, West Sumatera. The study was done from March until October 2011.  The aims of this research were to get the effect of compost from jengkol shell on chemical properties of paddy soil and rice yield.  The experiments were conducted in a greenhouse and the experimental units were arranged based on completely randomized design (CRD).  The treatments were application of compost K0 = 0 tons/ha (0 g/pot), K1 = 5 tons/ha (20 g/pot), K2 = 10 tons/ha (40 g/pot), K3 = 20 tons/ha (80 g/pot), K4 = 40 tons/ha (160 g/pot).  The data were compared to the criteria of soil chemical properties and plant data were statistically analysed for the variance.  If the F calculated > F table, the analyses were continued   by using DNMRT at 0.05 level of significance.  The results showed that application of 160 g compost/pot increased soil pH by 21.78%, N-total by 123.07%, organic-C by 65.84%, available P by 93.55%, K exch. by 238.35%, Ca exch. by 133.33%, Mg exch. by 90.00%, CEC by 238.90%, Cu exch. by 54,10%, as well as the yield by 12,68% compared to the treatment without compost application.Keywords : jengkol, nutrients, paddy soil, production

Gromoxone 267 SL Herbicide (GH) is widely used in weed control, and its contamination in the soil has the potential for contamination in agricultural land. The purpose of this study was to explore the effect of the application of soluble Gromoxone 267 SL herbicide on changes in the chemical properties of Inceptisols. This study used a completely randomized design with 4 treatments and 3 replications, namely A = 0% R (0.00 mL GH 7.34 mL H2O); B = 50% R (0.03 mL GH 7.34 mL-1 H2O); C = 100% R (0.06 mL-1 HG 7.34 mL-1 H2O) and D = 150% R (0.09 mL HG 7.34 mL-1 H2O), where 100% recommended soluble Gromoxone 267 SL herbicide (soluble) is assumed to be equivalent to (~) 100% Paraquat Dichloride (276 g L-1) in the Gromoxone 267 SL herbicide. The results of this study showed that 150% application of the recommended soluble Gromoxone 267 SL herbicide had a very significant effect on reducing CEC, total N, K, Ca and Mg-dd. It also had a significant effect on organic C and N of Inceptisols compared with control or without application of Gromoxone 267 SL herbicide.

The purpose of this study was to determine the best dose of swallow droppings that affect soil chemical properties with parameters of pH, Organic C, N, P, K on the soil and growth and yield of red chili. This research was carried out for 6 months starting from July 2017 to January 2018. The research location was on Jl. Mount Lingai North Samarinda. The design used was Randomized Block Design (RBD) consisting of five treatments and five replications. (P0) 0 g bokashi swallow bird polybag-1, (P1) 50 g bokashi swallow bird polybag-1, (P2) 100 g polybag-1, (P3) 150 g polybag-1, (P4) 200 g polybag-1. Soil seals were composted, then analyzed with soil pH parameters, organic C, N, P, K. The soil data obtained were analyzed based on the status of soil chemical research that had been developed by the Bogor research center in 2005. Plant data analyzed were plant height, number fruit/plant and fruit/plant weight. Plant data obtained were analyzed using variance, and followed by LSD testing at the level of 5%. The results of this study indicate that giving bokashi swallow droppings with a dose of 200 polybag-1 in P4 treatment showed an influence on some soil chemical properties, including soil pH from 5.01 to 5.31 with acid status; Organic C from 1.92 to 4.79 with very high status; Phosphorus (P) from 17.05 to 176.82 with very high status; Potassium (K) from 23.89 to 78.22 with a very high status on the soil. Meanwhile, Nitrogen (N) has decreased N levels from 0.26 to 0.25 with very low status on the soil. The bokashi application of swallow droppings showed a very different effect on the high growth of red chilli plants, while the yield of plants was not significantly different, namely the number of fruit and the weight of fruit/red pepper plants. The best response was found in P4 treatment which used a dose of 200 g polybag-1 with an average plant height of 32.12 cm; average number of fruits/plants 3.00; average fruit/plant weight 22.32 g.

The present research was conducted on two factor Completely Randomized Design (CRD) with eight treatments and three replications. A set of experiments were carried out to evaluate the effect of postharvest ethephon treatment and packaging on ripening of mango cv. Maldah. The treatments consisted of ripening agent i.e., ethephon and control treatment under different packaging condition i.e., fiber with hole, fiber without hole, plastic with hole and plastic without hole. The result revealed that different packaging condition and ripening agents influenced the ripening behavior of mango. The highest TSS (15.26), sugar-acid ratio (23.66) and juice content (126.05) were recorded with fiber (without hole) and the lowest TSS (12.60), sugar-acid ratio (9.01) and juice content (116.05) with plastic (without hole). The highest TA (1.44) was recorded with plastic (without hole) and the lowest (0.66) with fiber (without hole). Similarly, the highest BT (2.83) was recorded with fiber (with hole) and the lowest (1.66) with plastic (without hole). Firmness, sweetness, TSS and juice content were the highest with the interaction effect of fiber bag (without hole) and ethephon treatment. In conclusion, mango fruits with ethephon treatment packed in fiber bag (without hole) enhances quality and ripening of mango whereas under controlled condition and without hole plastic packaging mangoes had low quality performance in terms of physio-chemical properties.

The objective of this study was to analyze the effect of soil fertilization with sulfur-based fertilizers, sulfate and elemental sulfur forms on biomass production, nutrient characteristics of sorghum and soil chemical properties. The experiment was carried out in a 4 x 4 factorial scheme (four sulfur sources: single superphosphate, agricultural gypsum, elemental sulfur powder and elemental sulfur granulated with bentonite, and four sulfur doses: 0, 40, 80, 120 mgdm-3) using four replications in a completely randomized design, being cultivated in pots under greenhouse conditions. The sorghum was cultivated for a period of 51 days after emergence of the seedlings. The shoot dry mass, shoot macronutrients content, root and soil and pH of the soil were evaluated. There were interactions between sources and sulfur doses in the variables such as shoot dry mass, sulfur in the root, sulfur and calcium in the soil. Elemental sulfur (granulate) showed lower concentrations of phosphorus, sulfur and N:S ratio in the shoot. The concentrations of potassium, calcium and magnesium did not show significant differences, both for the shoot and the root. The pH of the soil was reduced depending on the sources and doses of elemental sulfur. The sources and doses of sulfur did not influence the levels of phosphorus, potassium, and magnesium in the soil. The elemental sulfur in the form of powder is the best source of sulfur for forage sorghum cultivated in soil with alkaline pH.

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.
