Abstract
This research aimed to examine growth and yield responses of various promising lines of upland red rice to different doses of P fertilizer and different levels of watering, by conducting pot experiment in a plastic house of the Faculty of Agriculture (University of Mataram), located in the experimental farm in Narmada, West Lombok, Indonesia. The experiment was designed according to Randomized Complete Block Design, consisting of three treatment factors, i.e. upland red rice genotypes (G1= M-G8; G2= M-G11; G3= M-G13; G4= M-G17); levels of watering (W1= 200 and W2= 300 ml/day); and doses of P fertilizer (P0= 0; P1= 100; P2= 200 kg/ha of SP-36 fertilizer). Each treatment combination was prepared in three blocks as the replicates grouped according to the different sources of the soil used to fill the pots. Results indicated levels of watering appears to have most dominant effects, in which the higher level of watering resulted in higher leaf number, panicle length, dry straw weight, filled grain number, and grain yield, but increasing P doses only increased plant height and grain yield, while genotypes were significantly different only in plant height, tiller number, panicle number and straw dry weight. Although both increased P doses and watering levels increased grain yield of red rice, there was a strong indication that increased P doses can increase grain yield only when level of watering is also increased, or vice versa
