EFFECT OF MULCHING SOIL AND BIOFERTILIZER BY YCORRHIZA FUNGI Glomus mosseae IN SOME CHARACTERERES YIELD TOW CULTIVARS TOMATO lycopersicon esculenatum CULTIVATED IN GYPSIFEROUS SOIL.

Abstract

Field experiment was carried out during spring season 2009 on two Tomatocultivars ;superqueen and Berek under gypsiferous soil. and soil mulching with threelevel: with out mulching, mulching with plastic covers and mulching with strew andthe other factor with out fungi inoculation and with fungi inoculation factorialexperiment with in split plots design was used to study: Tomato cultivars as themain split plot . where as, the other two factors biological fertilization and soilmulching which were distributed randomly with in the main spilt plots. L.S.D testunder %5 probability level was used to comparre between the means of treatments .The results could be summarized as follows;Tomato Berek cultivar was significant supereminent as compared withsuperqueen cultuivar in most characteres yield. Micorrhizal inoculation increasedsignificantly most studied properties as compared with the un inoculation treatments.Black plastic covers treatment was significant supereminent in early yield, totalyield, NO.of fruits,yield per plant wile With out mulch. second interation increasedsignificantly most studied properties as compared with signle factor. interactionbetween berek cultuvar,black plastic mulching and micorrhizal biofertilization weresupereminent for most of studied properties as compared with the effect of all singlefactors and the coupled interactions under investigation.
