“…The number of leaves on the plant was the highest with a treatment of 1.0 t ha -1 DPR and when the application of the DPR was lower, the number of leaves per plant was not significantly different. The results were similar to those obtained by Soeparjono and Kadiyasari (2021) on black soybean, Suntoro et al (2018) and Krismawati et al (2022) on maize. When DPR was applied to ryegrass, the dry weight increased (Yang et al, 2012).…”

“…Phosphate rock is relatively slow to release soluble P; however, compared to industrial P fertilizers, phosphate fertilizer is low in price, making it a very appealing fertilizer (Hellal et al, 2019). Moreover, dolomite is rich in calcium and magnesium and it helps improve soil conditions, such as neutralizing pH and soil structure and helps plants develop good roots (Krismawati et al, 2022). According to Chutichude et al (2010), dolomite is frequently utilized as soil fertilizer in a variety of soils for agricultural applications..…”

Background: The study was carried out to determine the amount of the dolomite phosphate rock (DPR) on the growth and seed yield of black sesame in a paddy field. Methods: A randomized complete block design was used for the field experiment, which included four treatments, each with four replications. Treatments were applied without the DPR and with 0.25, 0.5 and 1.0 t ha-1 DPR. Result: Experimental results showed that sesame plants were fertilized with the following formula: 60 N x 60 P2O5 x 30 K2O kg ha-1. Moreover, the addition of 0.5 t ha-1 DPR increased plant height (129.7 cm), the number of leaves and pods per plant (47.4 pods), total chlorophyll content in leaves (12.4 µg/cm2), the number of seeds per pod and seed yield (1.61 t ha-1). The phosphate content increased in the stem but not in the leaves and seeds. The pH of the soil (0-20 cm) and the amount of NH4+, NO3- and PAvailable were also increased.

Improving soil quality is vital so plants can adapt to climate change. Indonesia's acid soils cover about 147.5 million hectares, and are generally acidic, with low levels of calcium and magnesium, and high levels of aluminum. This study aims to study the effect of dolomite application on acid upland soils that have been applied with rock phosphate to improve soil chemical properties and increase maize yields. The research was conducted in Jati Agung using a randomized block design with 5 treatments and 5 replications. The treatment consisted of 5 application levels of dolomite: 0, 500, 1000, 1500, and 2000 kg ha-1. The size of the experimental plot was 10 m x 10 m. Hybrid maize varieties were used as indicators. The results showed that applying dolomite increased soil pH, Ca, Mg, and K levels and decreased exchangeable and Al saturation. It also increases plant height, maize yield, and biomass. The implication of this study is that the application of dolomite 1000 kg ha-1 after rock phosphate is applied can improve soil chemical properties in acid soils.

“…Increasing soil pH to neutral directly affects nutrients in the soil. The lime application can increase soil pH so that it can increase the availability of nutrients that can be absorbed by plants [8,9]. Measurement of soil nutrient status after the research indicated a decrease in soil nutrient levels (table 1).…”

Cocoa is known as shade-loving plants, i.e. plants that suitably grow with shaded conditions. Therefore, particular cultivation techniques are needed, such as planting shade trees to cover cocoa trees from direct sunlight exposure. The utilization of shade-loving plants from annual and seasonal crops, such as coconut and corn, can provide several benefits for farmers, including optimal early growth of cocoa seedlings, and the byproduct of shade-loving plants can provide short-term economic benefits for farmers. Corn plants in sustainable cocoa farm management are grouped as pioneer plants that can provide temporary shade so that cocoa plants can be protected from direct sunlight because cocoa is known as a shade-loving plant. One of the efforts to get short-term income for farmers is to utilize corn as an intercrop while allowing for the generative phase of cocoa plants. This research aimed to find the growth and production of several corn varieties and their effect on cocoa growth under shade. It was conducted in a farmer’s field in Bualo Village, Paguyaman subdistrict, Boalemo District, Gorontalo Province from June to November 2022. This research employed a Randomized Group Design consisting of four treatments of corn varieties, namely: BISI 18 (V1), BISI 99 (V2), NASA 29 (V3); and NK 6172, repeated 4 times with 16 experimental units. The results explained that all varieties of corn were able to adapt and tolerate conditions under coconut trees as shades, while the BISI 18 variety showed the highest production yield. Furthermore, there is a positive correlation between the use of corn as an intercrop with the vegetative growth of cocoa plants.
