Abstract

The aim of the research is to evaluate whether climate change has occurred in Simalungun Regency and study its impact on rice productivity and pest attacks. The research was carried out in March – May 2023 in Simalungun Regency, North Sumatra Province. With the results of the study of the impact of climate change on productivity and disease in rice plants in Sei Merbau village, Ujung Padang subdistrict, Simalungun district, carried out using the location survey method and taking climate data from the BMKG office, data on production, productivity and disease pests on rice plants were taken. from the agricultural service office. The climate data for 3 years that has been obtained is compared each year by looking at the results of developments in productivity and pests and diseases in rice plants in Sei Merbau village, Ujung Padang sub-district, Simalungun district. In 2018-2020, the climate in Simalungun district experienced fluctuations every year which could have an impact on the development of rice plant productivity and rice plant diseases in Simalungun district every year. There is a significant level of correlation between rainfall and rainy days on rice production and productivity in Simalungun Regency.

Abstract

The main objective of this research is to determine the growth response and production of glass gem corn plants (Zea mays L.) using trichocompost soil amendments and the application of eco enzyme. This research used a factorial randomized block design (RAK) consisting of 2 treatment factors with 16 combinations and 3 replications to obtain a total of 48 plots. The parameters observed in this study were Vegetative Growth which consisted of flower age, plant height, number of leaves, root length, leaf area, stem diameter, net assimilation rate, fresh and dry root weight, shoot fresh and dry weight, plant growth rate. . The second observation is production which consists of cob length, cob diameter, cob weight per sample, cob weight with sample husks/plants. The research results showed that the results of the analysis of trichocompost fertilizer content were Nitrogen 1.93%, P2O5 1.93%, K2O 3.56; C-Organic 25.35%; Cu 23.29 Ppm, Fe 0.23%, Mn 181.95 Ppm, Zn 0.01 Ppm, pH 8.71, and water content of 50.50%. Furthermore, the results of the analysis of the eco enzyme fertilizer content are Nitrogen 0.25%, P2O5 0.02, K2O 0.04; C-Organic 0.93%; Cu >0.0002 Ppm, Fe 34.44 Ppm Mn 4.43 Ppm, Zn 0.01 Ppm, pH .25. The use of fruit waste as liquid organic fertilizer and cow dung as organic fertilizer is effectively used to increase the growth rate and productivity of corn plants, especially galss gem corn.
