Abstract

Sweet corn (Zea mays L. var. saccharata) is a variety of corn that differs from regular corn due to its sweet taste, which is caused by its high sugar content. The productivity of sweet corn in the country is still low compared to other producing countries. The application of humic acid soil conditioner can enhance the absorption of micro and macro elements in plants. Humic acid can also improve plant growth by increasing bioavailability and nutrients through soil environment improvement around the roots. This study aims to determine the effect of humic acid soil conditioner and the appropriate dosage on the growth and yield of sweet corn. The study used a Non-Factorial Randomized Block Design (RBD) with 4 treatment levels: (H0: without humic acid soil conditioner (control), H1: 5 kg/ha, H2: 10 kg/ha, H3: 15 kg/ha). The results showed that the application of humic acid soil conditioner can increase plant height, cob diameter, and cob length of sweet corn. The best dosage of humic acid organic fertilizer for the growth and yield of sweet corn is 15 kg/ha. Keywords : sweet corn, soil conditioner, humic acid

Abstract

Soybean production in Indonesia has not shown a satisfactory trend, compounded by drought problems that adversely affect plant growth and metabolism. One of the various solutions offered is the use of drought-resistant/tolerant soybean varieties. This study aims to examine how drought-resistant/tolerant varieties differ from drought-susceptible varieties in their morphophysiological response to drought. The study was conducted in a plastic house in Aras Kabu Village, Beringin Subdistrict, Deli Serdang Regency, North Sumatra, using a randomised block design with two factors and three replicates. The first factor was soil moisture conditions, consisting of 80% field capacity (FC) and 40% FC. The second factor was the testing of the Grobogan and Dering varieties. The observation parameters consisted of the number of leaves and leaf K uptake. The results showed that there was a significant interaction between the use of varieties and drought conditions, where the Dering variety significantly reduced the number of leaves, while the Grobogan variety, which is susceptible to drought, increased leaf K uptake to survive. Keywords: soybean, drought, stress, varieties
