Abstract
The study was carried out on the experiment field of Ismailia Agricultural Research Station, Ismailia Governorate during the two successive summer seasons (2019 and 2020) using two genotypes of peanut (Giza 6 & Intro. 293). To study effect of bio-agent such as Streptomyces erythrogriseus 2 (100%, 75% and 50% cell suspension) and fungicide (Rizolex T 50% WP) on controlling soil borne fungi (Fusarium semilectum, Aspirigillus niger, Aspirigillus ochraceus, Tricoderma sp., and Penicilium sp.) on peanut crop. Results indicated that Intro. 293 was surpassed cultivar Giza 6 in most of growth characters and seed yield parameters. The concentration of 50% bio-agent Streptomyces erythrogriseus 2 with the two studied genotypes gave the highest result in chlorophyll a (55.10). The highest seed oil percent (52.43%) for Intro. 293 was observed with concentration 75% of bio-agent Streptomyces erythrogriseus 2, in the second season. The growth of the A. flavus fungus, Alternaria alternaria and Cladosporum sp. was inhibited 100%, when, Streptomyces erythrogieseus sub sp 2 treatment through all concentrations compared to control, seeds were subjected to seed healthy test. The percentage was less in case of Fusarium semilectum, Aspirigillus niger, Aspirigillus ochraceus, Tricoderma sp., and Penicilium sp. Phenolic compounds test showed that concentration 100% filtrate give the heights result 20.38 µg/g of fresh weight. CO2 test showed high percent in concentration 100% filtrate, 187 mg/100mg soil. An economic evaluation of the experiment was also conducted, where the concentration of 75% of bio-agent with the Intro. 293 gave the highest production value per acre of 9441.1322 pounds per acre in the first and second seasons.
