Pertumbuhan Beberapa Kultivar Padi Gogo (Oryza Sativa L.) Lokal Pada Berbagai Interval Waktu Penyiraman

Abstract

A common problem that often occurs on dry land is the availability of very little water so that it only relies on rainfall, this causes large fluctuations in soil moisture content, causing inhibition of metabolic processes in plants. One of the efforts that can be made in the development of upland rice will be faced with the availability of water. This research was arranged using a completely randomized design (CRD) with a twofactor factorial pattern. The first factor consisted of 3 local upland rice cultivars namely Uva Buya Cultivar (K1), Buncaili Cultivar (K2) and Kalendeng Cultivar (K3). The second factor consisted of five watering intervals, namely daily watering (P0), one-day interval watering (P1), every other day watering (P2), every three days watering (P3) and every four days watering (P4 ). Thus, 3 x 5 = 15 treatment combinations were obtained. The uva buya and buncaili cultivars were able to grow well at watering intervals of every day, one day to every two days. The kalendeng cultivar was able to grow well at watering intervals of every day and one day intervals. The uva buya and buncaili cultivars produced better growth than the kalendeng cultivar. Upland rice was able to grow well up to the level of watering interval of every three days. Keywords: Watering Interval, Local upland rice, Drought.
