تأثير التداخل بين المادة العضوية ولقاح الفطر Trichoderma harzianum في معايير نمو وأنتاجية نبات الطماطة esculentum Lycopersicon

Abstract

The interaction effect between organic agriculture and fungus inoculum T. harzianum on growth parameter and productivity of Tomato plant A field experiment was conducted in loamy sand soil at Al-najaf – province ,desert reigon.to study the effect of inter action between organic matter levels and the activity of T.harzianum fungus in planting Tomato crop. Three levels of organic matter were used 15, 30, 60 Ton/ha with three levels of T. harzianum inocculum 0 , 1 , 2gm/ m2 used RCBD Desigin . salt wells water was used with drip irrigation method . The aim of this study is to evaluate the population of T.h during7, 35, 63, 91, 119, 147 days and its role in improvement the growth parameter and productivity of Tomato plant . results showed superior fungus treatment at level of 2 gm/m2 of inoculum in increasing plant production which reached to 20.5 Ton /ha compared with the control which gives 15 Ton/ ha , while the interaction treatement at 30 Ton/ha level of organic matter and 1gm/m2 of inoculcm gives 25Ton /ha of Tomato compared with same level of orgainic matter alon which give 16 Ton/ha.Al so the inoculutm treatment have an increase in length of tomato plant which reached to 72, 85, 83cm for the treatment 0, 1, 2gm/ m2 respectively . results al so showed that the time affected on the population of fungus which give CFU 0.1 *1O6 for each gm/ dry soil after 7days 0f inoculation while after 147days became 1.5*103 CFU/gm of dry soil.
