Growth analysis of sweet corn plants treated with a soil amendment

Abstract

This study examined the effect of Zeolite soil amendment on performance (growth and yield) of sweet corn.The experiment was carried out in rice fields in KP. Mojosari, Mojosari District, Mojokerto Regency in MK II 2021 (April to September 2021), with 10 fertilization treatments which are the combination of the best Zeolite soil improver fertilization dose on sweet corn plants, including treatment A (control), B (Urea 200 kg/ha, ZA 100 kg/ha, NPK 275 kg/ha, without Zeolite), C (Urea 200 kg/ha, ZA 100 kg/ha, NPK 275 kg/ha, Zeolite 1,250 kg/ha), D (Urea 200 kg/ha, ZA 100 kg/ha, NPK 275 kg/ha, Zeolite 2,500 kg/ha), E (Urea 200 kg/ha, ZA 100 kg/ha, NPK 275 kg/ha, Zeolite 3750 kg/ha), F (Urea 200 kg/ha, ZA 100 kg/ha, NPK 275 kg/ha, Zeolite 5,000 kg/ha), treatment G (Urea 150 kg/ha, ZA 75 kg/ha, NPK 200 kg/ha, Zeolite 1,250 kg/ha), H (Urea 150 kg/ha, ZA 75 kg/ha, NPK 200 kg/ha, Zeolite 2,500 kg/ha), I (Urea 150 kg/ha, ZA 75 kg/ha, NPK 200 kg/ha, Zeolite 3,750 kg/ha), J (Urea 150 kg/ha, ZA 75 kg/ha). ha, NPK 200 kg/ha, Zeolite 5,000 kg/ha), which was repeated 3 times, using a Randomized Block Design (RAK), analyzed by ANOVA if significantly different followed by Duncan’s Significant Difference Test (DMRT 5%). Parameters measured were leaf area, leaf area index, plant growth rate, net assimilation rate, ear length, ear diameter, weight per plant ear and cob weight per hectare. The results showed that Zeolite soil enhancer was quite effective in increasing growth which affected the yield of sweet corn obtained. Provision of Zeolite soil amendment as much as 1,250 kg/ha accompanied by Urea fertilization 200 kg/ha + ZA 100 kg/ha + NPK 275 kg/ha obtained the highest yield of sweet corn cobs of 22.35 t/ha.

Application of liquid micro compound fertilizer to increase yield and agronomic feasibility of sweet corn

“…At the beginning of growth, namely the observation at 14 DAP did not show a significant increase in leaf area and was strongly influenced by the development of the number of leaves per plant (Table 5). According to the results research by Aisyawati et al (2022) that, the lowest leaf area per plant was found in the treatment without fertilization (treatment A), while between other fertilization treatments there was no significant difference [22]. This shows that the land used is less fertile so it is very IOP Publishing doi:10.1088/1755-1315/1253/1/012023 6 responsive to the application of fertilizer, although the variation in the increase in leaf area per plant is not significantly different between the doses of fertilization given to sweet corn plants.…”
