Abstract

  A field trial was conducted at Mallawi Agricultural Research Station, Minia Governorate, ARC, during 2016 and 2017 seasons in a high naturally infested field with charcoal rot and wilt diseases complex, as well as under artificially infestation with charcoal rot and wilt pathogens i.e. Macrophomina phaseolina and Fusarium oxysporum, respectively. The aim of this working to study the effect of intercropping guar with sesame at three planting densities of 100, 67 and 50% from sole guar and number of once and twice to reduce charcoal rot and wilt diseases complex, and yield and yield components of both crops. All intercropping patterns were significantly decreased disease incidence of charcoal rot and wilt diseases compared to the sole sesame under field and pots conditions. The intercropping 100% Sesame + 100% guar was the best pattern to reduce the incidence of charcoal rot & wilt disease complex in both seasons and pots experiment. Sesame seed yield/fad with guar at 50% plant density was increased by 32.66, 23.27% and 28.51, 18.58% than those of guar at of 100% and 67% in the 1 st and 2 nd, seasons, respectively. The highest value of total fresh yield/fad (ton) and total dry yield/fad (ton) of guar with sesame at intercropping pattern 100% guar were 5.91, 0.79 and 6.69, 0.69 ton/fad in the first and second seasons, respectively. Intercropping 50% guar with sesame and one cut guar recorded the highest values for LER, net return and MAI (monetary advantage index) in both seasons. Meanwhile, the lowest net return was recorded for intercropping 100% with two cuts of guar. Our study concluded that intercropping crop guar can be used for the protection of sesame charcoal- rot and wilt disease complex and produced greater seed yield than either crops grown alone.
