“…Sweet corn kernels' highest observed sugar content was found at a dose of 4.28 g. The K-Ca-Mg-S compound fertilizer contains potassium nutrients that function in sugar and starch formation. Potassium, although playing an essential role in plant growth, especially during the maturation period of plants, can affect photosynthesis in the formation of chlorophyll, seed filling and is essential in the formation of carbohydrates [10]. It is proven in this study that the application of 4.28 g / polybag K-Ca-Mg-S compound fertilizer produces the highest seed sugar content.…”

The natural mineral of polyhalite, which consists of potassium, sulphur, magnesium, and calcium, has the potential to be to supply various essential nutrients to complete the plant’s nutrient requirement, such as sweet corn. The aim of this study to determine the effect of multiple doses of K-Ca-Mg-S fertilizer on sweet corn plants. This research was conducted at Medan City, North Sumatra, with a height of ± 25 meters above sea level from March to May 2023. This study used a Non-Factorial Randomized Block Design with 5 replications and 5 treatments consisting of the dose of fertilizer, namely 0; 2.14, 4.28, 6.42, and 8.57 g/plant. The results of the study showed that several doses of K-Ca-Mg-S compound fertilizer were able to accelerate the male flowering age, which was 53.8 days after planting (dap), the female flowering age was 57.4 dap, and was able to increase the weight of husked cobs, namely 157.758 kg, and seed sugar content of 15.6 % Brix, but did not increase the harvest index.

“…According to Wirosoedarmo et al [4], efective depth afects root growth and development, making plants grow and develop properly. Moreover, the levels of organic C, total N, and CEC are infuenced by soil organic matter [76], while potassium plays a role in the growth and development of maize [77].…”

The significant effect of land quality on maize production has not been fully considered in the existing land suitability criteria. Therefore, this study aims to determine land suitability criteria for hybrid maize in Boalemo Regency based on the optimum yield and land quality. It was carried out in Boalemo Regency, Indonesia, where the land unit of 67 units was surveyed to obtain land characteristics data. A partial least square of structural equation model (PLS-SEM) with SmartPLS 8.0 was used to select a robust land quality controlling hybrid maize yield, while the boundary line method was used to determine optimum yield and differentiating of land suitability criteria. The result showed that land qualities that define the optimum yield of hybrid maize were root conditions, nutrient availability, nutrient retentions, land preparation, and erosion hazard. The soil characteristics were effective depth, coarse material, organic C, total N, K exchangeable, slopes, soil erosion, rock outcrops, and surface rocks. Furthermore, the highest optimum yield of 8.54 ton/ha was achieved by the total N and slopes for a very suitable class (S1), while the lowest of 5.58 ton/ha was obtained by exchangeable K for class S1. This showed that the combination of PLS-SEM and boundary line analysis was a better approach to developing new land suitability criteria for hybrid maize.

“…Sebagai pembanding digunakan urea dengan dosis 100% N, yang selanjutnya disebut sebagai perlakuan N standar. Aplikasi pupuk N dengan dosis 100% N didasarkan pada kebutuhan N, P2O5, dan K2O tanaman jagung, masing-masing 135 kg N/ha setara dengan 293,5 kg urea/ha, 75 kg P2O5/ha setara dengan 208,3 kg SP36/ha, dan 150 kg K2O/ha setara dengan 250 kg KCl/ha (Alfian & Purnamawati 2019).…”

Nitrogen (N) fertilizer of the urea type is very commonly used in Indonesia. The demand for this fertilizer is expected to increase, so an alternative is needed as a complement. Ammonium chloride (NH4Cl) is a by-product produced in the soda ash industry. This compound contains 26% N, which can be an alternative source of N nutrients for plants. The level of the following element, namely chlorine (Cl), is relatively high, so it is a concern that might affect the plant growth. This field experiment aimed to evaluate the effect of the application of ammonium chloride combined with potash fertilizers on the growth, production, and uptake of N and Cl nutrients in sweet corn plants. The trial was designed in a randomized group with nine treatments of 0%, 100%, 150%, and 200% N, combined with potassium sources from KCl and K2SO4. As a comparison, the source of N is urea at a dose of 100% N is referred to as the standard N treatment. Parameters observed included plant height, the weight of corn cobs and corn stover, N and Cl nutrient uptakes in seeds, leaves, and stems. The results showed that the application of ammonium chloride combined with different K sources markedly affected plant height, cob and plant stover weight, and N and Cl uptakes of sweet corn compared to controls. Applying N-ammonium chloride with KCl and K2SO4 showed no significant effect in growth and yield compared to standard N. The N dose showed no significant effect on plant growth and yield compared to the standard N dose. Keywords: by-product, nitrogen fertilizer, soda ash
