Humic acid is recommended to increase crop P uptake since it is capable of competing with P to be bound to soil adsorption complexes. Humic acid extracted from composted manure (MHA) is a good alternative to humic acid because it is more reactive and has a higher complexation ability compared with leonardite. Therefore, the effectiveness of soil-applied MHA combined with P was evaluated to improve corn yields in acidic soils from the aspect of crop nutrient uptake efficiency and crop physiological performance. Two high-yielding corn cultivars that are highly accepted by Indonesian farmers and resistant to downy mildew disease were subjected to five different types of MHA and P combinations. The amount of P fertilizer was equivalent to 120 mg P2O5 kg−1 soil. The H10P1 produced the most significant result p < 0.05 in terms of total crop dry weight, grain dry weight, a...

Indonesia is currently challenged by corn self-sufficiency, with a target to increase corn production by 1 t ⋅ ha −1. However, one of the major constraints of land for corn production is a low P availability. To support the increase in production, and provide a database of potential production, the identification of corn land that has P availability problems is extremely required. In this study, the approaches are to observe the distribution of soil parent material from geological maps, soil maps to determine the type of soil, statistical data from the statistics bureau to get the center area of corn, and field observations. From the survey conducted, we found that most of the land evolved from volcanic material, karst material, and acid soils are the soils with a problem of P. However, some areas of the soils showed a high P availability. Further identification of P availability in acid, volcanic, and karst soils needs to be done so that the database of potential corn production can be structured as a basis of corn land management policies in Indonesia.

This study evaluated the short-term effects of in situ biochar briquettes on nitrogen loss reduction and determined an optimum scenario for hybrid rice grown in an agroforestry system among kayu putih stands. This three-year experiment (2019–2021) was conducted using a randomised complete block design factorial with three blocks as replications. The treatments included biochar briquettes made from kayu putih waste (0-, 2-, 4-, and 6-grain plant−1 or 0, 5, 10, and 15 tonnes ha−1) and urea fertiliser (0, 100, 200, and 300 kg ha−1). The results demonstrated that the eco–environmental scenario was the most efficient strategy that improved the soil quality, the physiological characteristics, and the yield of the hybrid rice with the optimum application of the biochar briquettes at 5.54-grain plant−1 and the urea fertiliser at 230.08 kg ha−1.

This study aimed to evaluate the difference between biochar sources, namely Melaleuca cajuputi waste and rice husk, for controlled nitrogen loss in hybrid maize planted between Melaleuca cajuputi stands. A split-plot design with three replications was used. The main plot was composed of biochar sources (BS), i.e., without biochar application (WB), Melaleuca cajuputi biochar (MCB), and rice husk biochar (RHB). The subplot was the urea fertilizer dosage, i.e., 0, 150, 300, and 450 kg/ha. The observation parameters were nitrate reductase activity (NRA), total chlorophyll (TC), leaf photosynthesis rate (LPR), nitrogen loss (NL), nitrogen use efficiency (NUE), and seed yield per hectare (SY). The data were analyzed with ANCOVA and LS-means. The results showed that there was no significant difference between mixing MCB or RHB in UF for all hybrid maize parameters, whereas significant differences were observed wit...

It has potential to be used as an organic fertilizer source due to its nutrient content (macro and micro) which is higher than organic fertilizer from animals. The use of kayu putih waste is useful to complement and increase the efficiency of nitrogen fertilizer in soybean intercropping with kayu putih. This study aimed to determine the optimum values of kayu putih waste and nitrogen fertilizer based on three scenarios: economic, environmental, and eco-environmental. A two-year experiment (2018-2019) was carried out in a central composite design (CCD) with two replications as the response surface methodology (RSM) at the Menggoran Forest Resort, Playen District, Yogyakarta Forest Management, Indonesia. The treatments consist of biochar and compost levels made from kayu putih waste (0, 2.5, and 5.0 t ha-1) and nitrogen fertilizer levels supplied by ammonium sulfate (0, 50, and 100 kg ha-1) as independent variables. The observations conducted on nitrate reductase activity (NRA), total chlorophyll (TC), leaf photosynthesis rate (LPR), nitrogen loss (NL), nitrogen use efficiency (NUE), and seed yield (SY). The response variables were fitted in a full quadratic polynomial model. The results showed that the resource-based on the eco-environmental scenarios was the most favorable cropping strategy for the soybean production intercropping with kayu putih with the optimum value of 2.890 t ha-1 of biochar, 2.27 t ha-1 of compost, and 67.85 kg ha-1 of ammonium sulfate. This recommendation can reduce the use of ammonium sulfate by 32.

Though agriculture in this region makes the highest contribution to Gross Regional Domestic Product, the productivity of this sector is still low. Drought is a classic problem and represents the largest barrier in agricultural development, despite high precipitation. This paper describes the design of an efficient irrigation technology to increase agricultural productivity. Specifically, this research aims to determine marginal-land suitability, analyze and design a suitable model of rainwater-harvesting-based irrigation technology. Using the method of combining field study and desktop analysis, the results indicate that the land in the research site is considered suitable given the conditions of a particular treatment for the commodities of upland rice, soybean, corn, green beans, peanuts and cassava. The model rainwater irrigation reservoir is built by considering the drainage flow and the contour of the rainwater catchment area. The feasible irrigation distribution models are the pitcher irrigation system and perforated pipe irrigation system. The pitcher system from the existing reservoir can support a maximum of 24.75 m 2 of land, 120 plants and at least 66 service days. The optimum range of pitcher water is around 25 cm with a 50-cm space between plants and one pitcher serving 4 plants. Meanwhile, the perforated pipe is mounted near the root zone (10-25 cm) at the depth of 17.5 cm, with 25 cm left-right spacing between plants. An L-shaped pipe can serve 10 plants; one side is mounted underground while the other side is above the land surface for water intake. The pipe system from a reservoir can serve a maximum of 129.5 m 2 land. The study results lead to the conclusion that the most suitable irrigation model in the study area is the perforated pipe system.
