The Response of Potato to Differences in the Watering Intervals and Composition of the Growing Media in the Medium Plains

Jajang Sauman Hamdani, Sumadi Kusumiyati, Wawan Sutari, Maria Kristina

Abstract: The cultivation of potatoes in the medium land is constrained by low air humidity and high temperatures which causes a lack of water availability due to the high evapotranspiration. Therefore, watering intervals and growing media compositions are needed that can support the growth of potato plants. This research was conducted to determine the effect of the interaction between watering intervals and growing media compositions on the growth and yield of potato cv. Medians in medium land. The research was conducted at the Research Station Ciparanje Jatinangor, Faculty of Agriculture, Universitas Padjadjaran (±685 m above sea level),. The experimental was using Split Plot Design consisted of two factors. The main plot factor was the watering intervals, consisted of 3 levels. The sub-plot factor was the growing media compositions, consisted of 4 levels. The experimental results showed that there were some effects o fno interactions between watering intervals and growing media compositions on the, plant height, leaf area indexs, khlorophyl conten, stomata conductance and leaf water contenr elatif. Growing media composed of soil, compost, charcoal, cocopeat (4: 1: 1: 1) showedplant heigt, leaf area index, stomatal conductance, leaf relative water content, were higher than other treatments. Watering intervals of 2 days gave the highest plant height and stomatal conductance.
