Effect Of Shade, Organic Materials And Varieties On Growth And Production Of Upland Rice

Abstract: There is a shade factor and low organic matter content of the soil is a problem that needs to be addressed in the development of upland rice cultivation as intercrops in the plantation area. Based on these considerations, then one study that needs to be done is to conduct experiments on the effect of shade factor combined with the the provision of the organic material to the some varieties of upland rice that has been recommended nationally. The objective of experiment is to study the influence of shade, organic materials and varieties on the growth and production of upland rice. This research using experimental design of Split - Split Plot Design with 3 treatment factors and 3 replications or blocks. The first factor is the treatment of shade with 3 levels shade percentage (0%, 20% and 40%). The second factor is the dosage of organic material consists of 3 levels (0 g / polybag, 25 g / polybag, 50 g / polybag and 75 g / polybag). The third factor is the treatment of varieties consists of 4 types of upland rice varieties (Si Kembiri, Situ Patengggang, Situ Bagendit and Tuwoti). The research results showed that the effect of shade on upland rice varieties decrease number of tillers, number of panicles, number of productive grains, grain production per hill of uplnd rice plants and total sugar content of upland rice plants. Effect of organic matter increases number of panicles, number of productive grains, grain production per hill of upland rice plants and total sugar content of upland rice plants. It is known that the the variety of Situ Patenggang provides better growth and production compared with three other varieties (Si Kembiri, Situ Bagendit and Tuwoti) in shaded conditions.
