“…The Bima 19 variety with 131.5 kg ha -1 of N fertilizer provide the highest weight of 1000 grains with 314.33 g. This result is not different with the Bima 20 corn variety with 109 kg ha -1 and 131.5 kg ha -1 of N fertilizer and similar to JH 21 corn variety with 86.5 kg ha -1 and 131.5 kg ha -1 of N fertilizer. These results consistent with another study of Bima 19 maize variety that planted among young rubber plants on the weight of 1000 grains of 280 g [11]. Nitrogen fertilization with a dose of 112.5 kg ha -1 has the same seed weight different from a nitrogen dose of 22.5 kg ha -1 [16].…”

The need for maize in West Kalimantan is around 320,000 tonnes per year, most of which is still imported from outside the region. Cultivating the maize under the shade of coconut trees is an alternative to meet the needs of maize in West Kalimantan and hence improvement on the cultivation of maize under the shade of coconut trees should be taken seriously. This study aims to determine the effect of nitrogen (N) fertilizer on the growth and yield of hybrid maize under the shade of coconut trees. The research method used a factorial randomized block design consisting of 2 factors. The first factor is maize variety (Nasa 29, Bima 19, Bima 20, JH 21 and Pioneer 35) and the second factor is nitrogen fertilization (64 kg ha-1, 86.5 kg ha-1, 109 kg ha-1, and 131.5 kg ha-) of N, hence 20 treatment combinations are obtained and repeated 3 times. The results showed that the Nasa 29 variety with N fertilizer of 131.5 kg ha-1 produced the highest maize grains yield of 4.8 t ha-1. Therefore the using of Nasa 29 variety with the 131.5 kg ha-1 of N fertilizer is recommended for intercropping system under the shade of coconut trees.

“…The calculation of dry weight of kernel production per hectare indicated the highest yield in the BISI 18 variety. The results of this research agree with the research of Suparwoto et al [14]. The research reported that the BISI 18 corn variety can adapt well as an intercrop in rubber plantations.…”

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.
