Impact of Wheat Seeding Rates with Sugar Beet, Humic Acid and N Fertilizer Rates on Yield and Chemical In Both Crops

A field Experiment was conducted during 2022/2023 and 2023/2024 in Etay El-Baroud,  Research Station, El Beheira Governorate,(ARC), Giza, Egypt to study the effect of four fertilizer treatments (80% N of recommended + 10L. Humic acid fed^-1, 60% N of recommended + 10L. Humic acid fed^-1, 40% N of recommended + 10L. Humic acid fed^-1 and 100% N which is recommended fed^-1) under three intercropping rates of wheat with sugar beet (100% sugar beet + 12.50% wheat, 100% sugar beet + 25% wheat  and 100% sugar beet + 37.50% wheat). Split plot design with three replications. Results indicated that all studied traits of sugar beet achieved the highest values with 100% N fed^-1 or 80% N + 10L. Humic acid fed^-1. Sowing sugar beet under an intercropping rate of 100% sugar beet + 12.50% wheat recorded the highest values of yield and quality of sugar beet in both seasons. Interaction between intercropping of 100% sugar beet + 12.50% wheat and application of 100% N fed^-1 recorded the highest values on most sugar beet traits in the first and second seasons. Application of 100% N fed^-1 or 80% N + 10L. Humic acid fed^-1 recorded the highest values of wheat in both seasons.  intercropping rate of 100% sugar beet + 37.50% wheat recorded the highest grain yield of wheat in both seasons. Sowing wheat of 100% sugar beet + 37.50% wheat and application of 100% N fed^-1 achieved the highest yields of wheat. Using 80% N of recommended + 10L. Humic acid fed^-1 fertilizer treatment and the intercropping rate of 100% sugar beet + 12.50% wheat recorded the highest LER, MAI and income.
