Abstract

the experiment was effectuated at the experimental farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Egypt in 2017 and 2018 rice growing seasons to determine the performance of Sakha 107 rice cultivar as affected by inoculation of Arbuscular Mycorrhizal fungi (AMF) under different irrigation intervals. The experiment was carried out in a split plot design with three replications. Irrigation treatments (continuous flooding (I1), irrigation every 6 (I2), 9 (I3) and 12 days (I4) considered as the main plots. However, the sub plots were occupied by two levels of inoculation of AMF, control (M1) and inoculation seeds in nursery bed by 1.2 kg ha-1 (M2). Results revealed that growth, grain yield and its attributes of Sakha 107 rice cultivar, as well as N and P uptake by grain were significantly influenced by irrigation treatments in both seasons. I1 treatment gave the highest values, followed by I2 treatment, while I4 treatment recorded the lowest values. The M2 treatment increased the previous parameters as a compared to M1 treatment. The average reduction in grain yield were found to be 3.48, 14.96 and 24.59% with corresponding values of water saved of 6.62, 12.46 and 25.00% when the interval period was prolonged up to 6, 9 and 12-day, respectively. I2 treatment gave the highest values of productivity of irrigation water (PIW) followed by I4 treatment.
