Response of Pod Quality Of Snap Bean (Phaseolus vulgaris l.) To Rhizobium Inoculation, And Foliar Spray With Iron And Boron

This study was conducted during the season of 2021/2022 and 2022/2023 seasons.at the experimental Farm of Horticultural Research Station, Kassasin Region, Ismailia Governorate, Agricultural Research Centre, Egypt to investigate the effect of rhizobium inoculation and Fe and B as foliar application on pod quality of snap bean cv. Poulista under sandy soil conditions, The layout of the experiment was laid out in randomized complete block design (RCBD) with three replicates. The experiment included 10 treatments as follows: T1 (control), T2 foliar application with Boron (B) at 25 ppm , T3 foliar application with Boron (B) at 50 ppm,T4 foliar application with iron (Fe) at 50 ppm, T5 foliar application with iron (Fe) at 100 ppm, T6 Seed inoculation with Rhizobium , T7 Rhizobium seed inoculation + foliar application with B at 25 ppm, T8 Rhizobium seed inoculation + foliar application with B at 50 ppm, T9 Rhizobium seed inoculation + foliar application with Fe at 50 ppm, and T10 Rhizobium seed inoculation + foliar application with Fe at 100 ppm. Results indicated that Rhizobium inoculation +foliar spray with B at the rate of 50 ppm, being the most effective on pod quality, i.e. N, B, Fe, total carbohydrates, total protein contents and lowest percentage of fibers. Conclusively: it can be concluded that Rhizobium inoculation and foliar spray with B at the rate of 50 ppm, increased pod quality of snap bean.
