Abstract

The study conducted at the Integrated Laboratory of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang, aimed to formulate granule and liquid biofertilizers for corn cultivation on dry land in Indonesia, covering 144.47 million hectares. Corn is a crucial agricultural commodity in the country, aligning with the Sustainable Food Self-Sufficiency Policy program. Fertilizers, especially biological ones with plant growth-promoting rhizobacteria (PGPR), play a pivotal role in enhancing both the quality and quantity of corn production. The research utilized a Nested Split Plot Design, considering varying levels of drought stress (100%, 70%, and 40% of field capacity) and bacterial density (control, 10^9, 10^8, and 10^7). Results indicated no significant interaction between granular and liquid fertilizer densities across different field capacities. While the PGPR consortium in both fertilizer types showed limited effectiveness in boosting maize growth and yield, the highest average performance was observed at a density of 10^7. Additionally, certain stress levels did not contribute to increased maize growth and yield, except for the 100% field capacity treatment. It was noted that extreme temperatures, reaching up to 54°C in the plastic house, might have hindered the expected interaction. Plant growth tends to decrease drastically below 15°C or above 40°C, as these temperatures activate physical and chemical processes in plants. The study underscores the importance of considering environmental factors in optimizing biofertilizer effectiveness for sustainable corn cultivation on Indonesian dry land.

Abstract

Basil can be grown in all regions of Indonesia. The purpose of this study was to identify the response of 2 types of basil against the use of N fertilizer dose on the early growth. In the growth process, plants require sufficient nutrients so that the physiological processes in plants’ organs can be held properly. The nutrients used by plants can be sourced from within the soil itself or in the form of fertilizers that have been put into the soil. Plants will grow properly if the elements needed by plants are fulfilled. The research was carried out from February to April 2022 at the Experimental Field of the Faculty of Agriculture and Animal Husbandry at the University of Muhammadiyah Malang. The design used in this study was the factorial Randomized Complete Block Design (RCBD) with a treatment dose of Urea fertilizer in basil type. The results showed that there was no interaction between the types of basil and the dose of urea at all the observation parameters. On the other side, the type of basil affects the parameters of the number of leaves, plant height, and total fresh weight where the type of tidore basil was better than other types of basil. Furthermore, the urea fertilizer dose treatment affected the number of leaves, plant height, and total fresh weight where the better urea fertilizer dose was N125.
