فعالية المعاملة بجسيمات الزنك النانوية المحضّرة بطرائق مختلفة في تشكّل العقد الآزوتية ومحتوى البذور من البروتين والجدوى الاقتصادية لصنفين من الفول العادي

Abstract

This research was conducted in the countryside of Safita area, Tartous Governorate during the two agricultural seasons 2021/2022 and 2022/2023 according to a randomized complete block design (R.C.B.D) with a split plot system with three replicates for each treatment. The experiment included four different treatments with zinc oxide nanoparticles. Two treatments by soaking the seeds with biologically and chemically synthesized zinc nanoparticles at a concentration of 25ppm, and two treatments by foliar spraying with biologically and chemically synthesized particles at a concentration of 50ppm, during three stages of plant growth in addition to the control.

The results showed the Cypriot variety plants sprayed with biologically synthesized nano zinc outperformed number of nitrogenous nodules (79.2 node/plant) and biological yield (6250 kg/ha). The plants of Hama2 variety sprayed by chemically synthesized nanoparticles showed superiority in the weight and size of nitrogenous nodules (2.74 g, 2.88 cm³) respectively. Hama2 plants treated by soaking seeds with chemically synthesized nanoparticles achieved the highest value for the protein content in seeds, reaching (26.24 %). The highest value of economic feasibility achieved with the treatment by soaking seeds with biosynthesized nanoparticles, reaching (199.4 %).
