Pengaruh Sudut Potong Bibit Singkong Varietas Garuda Terhadap Gaya Tekan Penanaman dan Respon Pertumbuhan

Abstract

Cassava is the main food source that has high economic value and is one of Indonesia's local food sources after rice and corn (Adielea et al., 2020). The main problem in planting cassava seeds is the large compressive force required to plant the stems into the soil. If the compressive force is too great, it can cause damage to the seedlings, changes in stem orientation, and difficulty in planting large quantities efficiently. This research analyzes the effect of variations in the cutting angle of Garuda variety cassava seedlings on the compressive force and plant growth response. Optimal cutting angles are expected to reduce the physical burden of planting, accelerate growth and increase productivity. This study used cutting angles of 0°, 20°, 35°, and 45° for testing. This research uses a RAL factorial design with two factors, namely cutting angle (A) and number of shoots (T). The tools used include knives, rulers, digital scales, as well as materials such as air, fertilizer and Garuda variety cassava seeds. From the research results for cutting angle A2, the compressive force required to reach a depth of 7 cm is greater compared to cutting angles A3 and A4, that is, it requires a load of 4 kg, while A3 requires 3 kg, and for A4 treatment it only requires 2 kg. Treatment A4 has the highest efficiency because the shape and nature of the A4 angle are sharper, allowing for a more even distribution of pressure at the end of the bar. In general, the cutting treatment model (A) affects plant height, number of leaves, number of roots. The amount of tuna (T) treatment affected leaf area and plant height.
