Sweet corn (Zea mays saccharata Sturt.) is such a popular commodity that it has good market opportunities. Increase productivity of sweet corn, necessary through improving its physical, chemical, and fertility properties. Continuous use of inorganic fertilizers can reduce soil fertility. Biofertilizer is an alternative to improve and enhance soil quality to increase growth and increase plant’s yield and quality significantly. The study aimed to determine the effect of biofertilizers’ application on the growth and yield of sweet corn on the upland. The research was conducted in 2016 in Tapin district, South Kalimantan Province. It is using a randomized block design with four treatments and eight replications. The treatments consisted of Po without biofertilizer + NPK fertilizer at a dose of 100%, P1 biofertilizer + NPK fertilizer at a dose of 100%, P2 biofertilizer + NPK fertilizer at a dose of 75%, P3, biofertilizer + NPK fertilizer at a dose of 50 %. The variables observed were plant height, cob weight with husk, cob weight without husk, cob diameter, cob length, number of seed columns, and production. The results showed that applying biofertilizer increase cob weight and sweet corn production.

Sweet corn (Zea mays saccsharata Sturt.) is one of the plants that is widely produced and a source of food staples in Indonesia, such as processed food, drinks, and so on. The low productivity of sweet corn in North Lampung is caused by the use of excessive doses and the wrong fertilization method. This problem can be overcome by implementing a good cultivation system, including applying fertilization with the right dosage so that plants can produce according to their potential results.The purpose of this study was to determine the effect of NPK fertilizer treatment on the growth and yield of sweet corn at the best dose of NPK fertilizer on the growth and yield of sweet corn. This research was conducted experimentally using RAL (Completely Randomized Design). It consists of one factor with 3 levels, namely K0: Control, K1: Giving NPK 150 kg/ha (1.8 kg/plant plot) K2: Giving NPK 300 kg/ha (3.6 kg/plant plot).The results showed that the NPK treatment had a significant effect on plant height at 30 HST. The stem diameter showed a significant effect when the sweet corn was 30 and 45 HST. The number of leaves shows that NPK fertilizer has no real effect. The length of the cobs with husks, the length of the cobs without husks, the weight of the husked cobs, the weight of the cobs without husks and the weight of the stover showed real results. 

Sweet corn fruit is one of the food favored by the people of Indonesia. The growth and yield of sweet corn can be increased by fertilizing. Research on the response of sweet corn growth to organic and NPK fertilizer was conducted in the Terong Tawah Village, West Lombok Regency. The purpose of this research was to determine: (1) response of the growth of sweet corn to the organic fertilizer treatment, (2) response of the growth of sweet corn to the NPK fertilizer treatment, (3) the effect of the interaction between organic and NPK fertilizer on the growth of sweet corn. The growth parameters of sweet corn are stem height, leaf lenght, number of leaf and stem diameter. Research data were analyzed using analysis of variance. The results showed that: (1) sweet corn growth has a positive response to the organic fertilizer, organic fertilizer can increas stem height, leaf lenght, number of leaf and stem diameter, (2) sweet corn growth has a positive response to the NPK fertilizer, NPK fertilizer can increase all growth parameter, (3) the interaction between organic and NPK fertilizer has no significant effect on all growth parameters, (4) the optimum dose of organic fertilizer is 1.5 kg m-2 of agricultural land, (5) The treatment of 6 g NPK fertilizer was better than other treatments.

This study aimed to evaluate the effect of compost fertilizer and potassium chloride (KCl) fertilizer, as well as their interaction, on the growth and yield of sweet corn (Zea mays saccharata Sturt). The experiment was conducted from May to August 2022 in Kuning Village, Bambel District, Southeast Aceh, using a factorial randomized block design with two factors: compost dosage (480 g/plot, 960 g/plot, 1,440 g/plot) and KCl dosage (20 g/plot, 40 g/plot, 60 g/plot), each replicated three times for a total of 27 plots. Observed parameters included plant height, stem diameter, leaf area, days to flowering, ear length, and ear weight per plot. Results indicated that compost and KCl fertilizers significantly affected plant height, leaf area, days to flowering, and ear length, but had no significant effect on stem diameter or ear weight per plot. The interaction between compost and KCl produced the highest plant height (165.89 cm) and ear length (21.69 cm) in treatment K3C1. The findings suggest that optimal fertilization using compost and KCl can enhance sweet corn productivity by improving vegetative growth and reproductive development. Nevertheless, the absence of significant effects on stem diameter and ear weight per plot indicates that nutrient balance, especially nitrogen (N) and phosphorus (P), remains crucial for maximizing yields. Therefore, integrating compost and KCl with complementary sources of macronutrients could promote more consistent outcomes. This research also highlights the role of organic matter in enriching soil fertility, maintaining soil structure, and supporting sustainable agriculture. The combination of organic and inorganic fertilizers demonstrates the potential for eco-friendly crop management practices that balance productivity with environmental responsibility. These results provide valuable insights for farmers, agronomists, and policymakers in developing efficient fertilization strategies for sweet corn cultivation within local conditions.

Plant growth regulator is one of the major factors affecting sweet corn growth and yield. Although many worldwide studies were done to evaluate the effect of this factor on sweet corn, it is still necessary to do more study to add knowledge in this area because environmental factors will have significant effect on growth and yield of sweet corn. Experiments were performed on August to December 2018 using split plot design with four replications. Analysis of variance (ANOVA) with probability value @ 0.05 using LSD was used to analyse the obtained data. Objective of the experiment was to increase quality component of high plant density using application of plant growth regulators. The experiment was carried out at Institute of Bioscience, UPM, Serdang with application of different type of plant growth regulators (IBA and GA3), different concentrations (0, 50 and 100 mg/l) and time of applications (vegetative and reproductive growth stages). A significant variation in growth rate when GA3 produced the tallest in plant height (4427.068 cm/week), while IBA produced optimum in stem diameter (16.420 cm/week) both at 100 mg/l at vegetative stage. Application of PGR during vegetative stage was the highly significant in cob weight (456.76 g) followed by reproductive stage (444.76 g). Indole-butyric acid produced the optimum significant results on cob length at 18.80 cm compared to gibberellic acid at 18.53 cm. Concentrations stated significant results with the highest was 100 mg/l on cob diameter at 5.66 cm followed by 50 mg/l at 5.46 cm and the lowest was 0 mg/l at 5.26 cm. For quantity components, application IBA at 100 mg/l during vegetative stage produced the highest yield per hectare at 51, 840 kg/ha. This experiment indicated that interaction of plant growth regulators and concentrations in two times of applications would optimize plant growth and afterwards increase yield components.
