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.
不同灌溉间隔下接种丛枝菌根对萨哈107水稻生产性能的影响
本试验于2017年和2018年水稻生长季在埃及Kafr El-Sheikh Sakha水稻研究与培训中心(RRTC)的实验农场进行,以确定不同灌溉间隔下接种丛枝菌根真菌(AMF)对Sakha 107水稻品种生产性能的影响。试验采用裂区设计,3个重复。以连续淹水(I1)、每6天灌一次(I2)、每9天灌一次(I3)和每12天灌一次(I4)为主要处理。各亚样地采用对照(M1)和苗床接种种子(1.2 kg ha-1 (M2))两个接种水平。结果表明,灌水处理对萨哈107的生长、产量及其性状、籽粒对氮磷的吸收均有显著影响。I1处理最高,I2处理次之,I4处理最低。与M1处理相比,M2处理增加了上述参数。当间隔期延长至6、9和12 d时,籽粒平均减产3.48%、14.96%和24.59%,节水6.62%、12.46%和25.00%。I2处理灌溉水生产力最高,其次是I4处理。
