Growth response of various rice varieties showed a different result to the application of Vesicular Arbuscular Mycorrhiza (VAM) in rainfed lowland rice field. The purpose of this study was to determine the leaf area index, leaf area duration, crop growth rate, net assimilation rate and relative growth rate of rice varieties applied with the treatment of VAM in rainfed lowland rice field. The research design was Randomized Completely Block Design with 2 factors and 3 replications. The first factor was rice varieties (IR64, Mentikwangi, Pepe, Mekongga, Way Apo Buru, Inpari, Situbagendit and Mamberamo). The second factor was the application of VAM (without VAM and with VAM). The research was conducted in the rice field in Demangan, Sambi, Boyolali, Central Java, Indonesia with 113 m above sea level. The results indicated that the VAM applications can increase the leaf area index of IR64, Mentikwangi, Pepe, Way apoburu, Inpari and Mamberamo variety; leaf area duration of IR64, Pepe, way Apoburu and Inpari variety; crop growth rate of all varieties except mekongga and mamberamo; net assimilation rate of IR64, Pepe and Inpari variety and relative growth rate of Mekongga variety. A significantly positive correlation was obtained between the leaf area index to the leaf area duration, crop growth rate, net assimilation rate and relative growth rate. The application of VAM to various of rice varieties in rainfed lowland rice field can increase the leaf area index, leaf area duration, crop growth rate, net assimilation rate and relative growth rate. There was a significance and positive correlation between the leaf area index to the leaf area duration, crop growth rate, net assimilation rate and relative growth rate. |
