| Abstract | ||
| A field experiment was conducted at Agricultural Research Station Farm in Shandaweel Island, Sohag Governorate to assess the intercropping for grain sorghum with soybean during 2020 and 2021 seasons under different systems about yield and its attributes of the two crops. The experiment was carried out in a randomized complete block design (RCBD) using strip plot arrangement with three replications. The obtained results showed that foliar spray with salicylic acid and intercropping system enhanced significantly all studied soybean and sorghum traits in this study in both seasons. Thus, the highest mean values of previous measured traits were observed from plants that were sprayed with salicylic acid at the rate of 100 ppm of the two crops in the two successful seasons. In addition, maximum yield and its attributes of sorghum were produced from intercropping system of 2 rows sorghum: 2 rows soybean in both seasons. On the other hand, the maximum soybean yield and its related traits were obtained from intercropping system 1 sorghum: 1 soybean and 2 sorghum: 2 soybean of sorghum and in the first and second years, soybean respectively. The greatest ratios of land equivalent (LER) which wear 1.33 and 1.67 in the two respective seasons) were obtained from 2 sorghum: 2 soybean intercropping system under 100 ppm salicylic acid. The greatest values of monetary advantage index (MAI) (6750.40 and 17000.80 LE in the first and second seasons, respectively) were recorded from intercropping system of 2 sorghum: 2 soybean under100 ppm salicylic acid. | ||
