| Summary: | <p align="justify">Indonesian SRI cultivation technique method is an effort intensification process in increasing rice production with the use of compost that acts as plant microbioreactor. Currently, SRI method has been developing semi-organic and non organic with the addition of synthetic fertilizers. The application of drip irrigation certainly can improve the efficiency of water use and support the SRI method. Differences in technology and inputs on the cultivation can affect the production of biomass and water consumption of plants. In this study the method used to calculate actual water consumption of paddy (ETc) (mm / day) by calculated the weight difference of polybag without holes after 24 hours in the screen house. The water productivity of crop is calculated by dividing the harvest biomass results with the volume of water used (kg / m3). This study used a randomized block design with 4 treatments and 6 repetitions. Data were analyzed by ANOVA statistic test and 95% DMRT advanced test. The results showed the highest water consumption to the lowest on the treatment is TKP 6.48, TK 6.31, TP 5.15, T 3.81 mm / day. Water productivity based on dry grain from the highest to the lowest on the treatment is TK 1.39, TKP 1.33, TP 0.92, T 0.46 kg / m3. While water productivity based on total dry biomass from the highest to lowest on the treatment is TKP 4.74,TK 4.27, TP 3.22 and T 2.32 kg / m3 (Exp. T: Soil, K: Compost, P: N, P, K Fertilizer). Based on the DMRT test 95% there is no significant difference in the TKP and TK treatment both on the results of water consumption and water productivity. Based on the comparison with the literature, drip irrigation can decrease paddy water consumption by 27% and increase paddy water productivity by 54% compared to traditional irrigation.<p align="justify"> |
