Influence of aqueous extracts from banana peel and soybean plants on soybean grain yield

Abstract

Foliar aqueous extract application has a positive effect on soybean yield and quality. The aim of this research wos to examine the influence of foliar application of aqueous banana peel and apical soybean plant part extracts on the yield of five soybean varieties that are of different maturity groups. This way, plant material would be used for soybean grain yield increase, and synthetic artificial fertilizer use would be avoided along with environmental polution. The results were processed via tri-factorial experiment variance analysis, and significancy of differences was tested via LSD test. Foliar application of aqueous banana peel extract increased soybean yield in a three-year experiment by 4.07% (annually from 1.33% to 6.62%), and the application of aqueous apical soybean plant part extract by 4.21% (annually from 1.21% to 6.90%). Greater yield increase was recorded during years that were unfavorable for soybean production, with the varieties Rubin (5.69% and 5.90%) and Merkur (4.34% and 4.40%) having a greater yield increase compared to other soybean varieties included in the experiment (NS Kaća 3.73% and 3.30%, NS Maximus 3.37% and 3.76%, NS Apolo 3.04% and 3.38%). The year immensely influences soybean yield, primarily depending on precipitaton distribution and quantity and temperature conditions during the vegetation period. Aqueous banana peel and apical soybean plant part extracts significantly increase soybean yield.
