Potential Growth of Corn Plants in Vegetative Phase with Application of Volcanic Ash and Straw Compost in Karo Regency

Abstract

Corn is third importance of the food crop group, behind rice and cassava. The demand has been rising yearly, especially for sweet corn. The aim of this research to determine of application volcanic ash (A), and straw compost (J), also the interaction of the two treatments in vegetative growth of maize plants. With a Randomized Complete Block Design (RCBD), in three levels for each treatment which of 9 treatments in three reps. R-Studio 4.3.2 was used to analize the data with DMRT test (5%), if the result was significant different. The study was showed that of two treatments had a real effect on plant height; stem diameter, number of leaves, and leaf area. Similarly the results for the interaction, between two and two treatments were significantly different.  After application to corn plants of volcanic ash  and straw compost were showed the better effects on vegetative growth of the plants. This indicated that the two treatments can used for corn vegetative growth.
