Abstract
Sweet corn has a sturdy and strong stem growth and is very suitable for cultivation in tropical climates. Research on the effect of horse manure compost combined with NPK fertilizer on the growth of sweet corn has been done with the aim of obtaining information: (1) the effect of different doses of horse manure compost on the growth of sweet corn, (2) the effect of different doses of NPK fertilizer on the growth of sweet corn, (3) The interaction effect of horse manure compost and NPK fertilizer on sweet corn vegetative growth. The application of NPK fertilizer was carried out with 4 treatment doses while the application of horse manure compost was carried out with 5 treatment doses. In this study, information was obtained (1) the application of NPK fertilizer increased the growth of sweet corn, (2) the application of horse manure compost increased the growth of sweet corn, (3) There was no increase in growth of sweet corn due to the combination treatment of NPK fertilizer and horse manure compost
Highlights
Sweet corn has a sturdy and strong stem growth and is very suitable for cultivation in tropical climates
Based on the above background, research was conducted on the vegetative growth of sweet corn (Zea mays L. saccharata) due to differences in the doses of compost and NPK fertilizer
The highest number of leaves was 14 leaves, found in the combination treatment of 1.8 kg of horse manure compost and 8 grams of NPK fertilizer Te Anova test gives the result that the interaction of compost and NPK fertilizer treatment had no significant effect on the total of sweet corn leaves
Summary
Sweet corn has a sturdy and strong stem growth and is very suitable for cultivation in tropical climates. Efforts to increase the growth of sweet corn can be done by applying fertilizer to the growing media. Some researchers found that the use of compost is very supportive of increasing plant growth. The treatment of compost and phosphorous fertilizer with a dose of 3 grams gave a very significant result in increasing plant height and leaf area with the highest green bean height reaching 32,5 cm, the most leaves being 13,5 leaves and the highest leaf area being 12,55 cm (Suratmin at al., 2017). Composting can increase the growth of green beans (Vigna radiate L.) which included the parameters of stem height and plant leaf area. Based on the above background, research was conducted on the vegetative growth of sweet corn (Zea mays L. saccharata) due to differences in the doses of compost and NPK fertilizer. The aims of this study were to determine: 1) the effect of different doses of horse manure compost on the growth of sweet corn, (2) the effect of different doses of NPK fertilizer on the growth of sweet corn, (3) The interaction effect of horse manure compost and NPK fertilizer on sweet corn vegetative growth
