Abstract:
The research was carried out in the gardens nursery of Tishreen university in the spring of the agricultural season (2020), within net plastic bags, and used in the research, sandy clay virgin soil ,to study the effect of double inoculation with two biofertilizers Arbuscular Mygorayza Fungi(AMF) andTrichoderma harzianum (T.h),on the growth and productivity of the potato crop (Spunta variety),the randomized complete block design (RCBD) was adopted to implement the research, the research included studying the effect of double inoculation with the biofertilizers (AMF),(T.h)with or without adding the recommended mineral fertilizers for potato plants with percentages of (25%,50%) and comparing it with the control without mineral fertilization and treatment of farms which the recommended amount of fertilizer was added per unit area for one plant (6.5g/plant potassium sulfate 50% ,8.5g/plant triple super phosphate 46% ,5.85 g/plant ammonium sulfate 33%),in three replications, the results showed that thedouble insemination treatment with biofertilizers, in (AMF+T.h) with the addition of 50% of the recommended amount of mineral fertilizer,it was significanty superior to all treatments for the studied traits compared with the control,it also achieved double insemination treatment with biofertilizers (AMF+T.h) only a significant increase in the area of the leaf surface, the number of leaves, the height of plants, the size of large tuber,and the standard production,as for the average tuber weight and plant productivity,the increase was not significant compared to the control,thus the effective role of double inoculation with biofertilizers (AMF+T.h) is evident in reducing the amount of mineral fertilizers(50%)while increasing productivity
KeyWords: Potato, Bio-enriched (AMF), Bio-enriched (T.h), the growth, productivity
