“…However, it would be better to combine the treatment with organic materials, such as Empty Fruit Bunch (EFB) which could increase the root growth (Santoso et al, 2019). The techniques need to be combined with cover crop management to reduce the erosion rate (Fuady et al, 2019), help maintain soil moisture, and the litter can enrich soil organic matter (Ariyanti et al, 2016).…”

Spodosols have been widely used for oil palm plantations, specifically in Kalimantan, Indonesia. However, they are sub-optimal for agriculture due to a lack of water and nutrient-holding capacity and a spodic layer that limits plant root development. Therefore, proper agriculture practices are needed for oil palm to enhance its potential yield. This study aims to determine the effect of the mounding technique on the physiological performance and yield of oil palms in spodosol. The study location was well-managed, with eight blocks of oil palm plantations planted in 2008 on spodosols (Typic Haplohumod) in Central Kalimantan. The mounding technique was applied to four blocks of oil palm planted in 2015, while the remaining four were left without mounding. The parameters observed were soil moisture, transpiration, number of bunches, bunch weight, and yield. The results showed that the average moisture in the mounded soil was 4% greater than the control. Additionally, the average daily transpiration of oil palm with the mounding was up to 2.30 mm day-1 or three times higher than the control. The implication was that the average yield of oil palm increased from approximately 1.84 to 3.71 tons ha-1 year-1 compared to no-mounding treatments. Furthermore, the average yield was 19-66% higher than the block without the mounding application.

“…Bima is high 17.23 tons/ha, then biological organic fertilizer can increase nutrient N absorption (201.33, 182.67, 170.67 and 161.33)% nutrient P (357.89, 273.68, 173.68 and 142.11)% and soybean yield (228.00, 208.00, 201.33 and 19 4.67) % (Marlina & Gusmiatun, 2020). According to (Fuady & Satriawan, 2019). Provision of organic fertilizers combined with inorganic fertilizers can increase the chlorophyll content of leaves (Buyana et al, 2019).…”

One effort to increase food security is to increase rice production by providing adequate nutrition to rice plants with organic fertilizers and growth regulators (PGR). The aim of this study was to measure the growth and production of black rice (black oryza), as well as the distribution of the average plus or minus data through the treatment of various concentrations of PGR and doses of organic fertilizer. The research design was a two-factor factorial randomized block design. The first factor of PGR concentration (Z) consisting of 5, namely 0 (Z0), 1 (Z1), 1.5 (Z2), 2 (Z3) and 2.5 (Z4) ml/L of water. The second factor of organic fertilizer (P) consisting of 5, namely 0 (P0), 1 (P1), 2 (P2), 3 (P3) and 4 (P4) tons/ha. The treatment was repeated 5 times so that 125 experimental units were provided. The best grain yield 47.03 g/panicle was resulted from a single effect of PGR treatment at a concentration of 2 ml/L, whereas single treatment using organic fertilizer at a dose of 4 ton/ha produced grain of 46.23 g/panicle. The best combination of PGR concentration of 2 ml/L of water with organic fertilizer 4 tons/ha, resulted the highest grain yield of 50.24 g/panicle, equivalent to average dry harvested grain of 5.02 ton/ha or 3.26 ton/ha of dry unhusked grain. The distribution of the average plus minus data is good with a low average distribution for all measurement components.
