The Effect of The Dates of Application of Biohealth Fertilizer and Levels of Mineral Fertilization on The Yield and Components of The Legume Crop (Vicia Faba L.)

Abstract

A field experiment was conducted during the winter semester 2020-2021 in Wasit Governorate - University of Wasit - College of Agriculture, Iraq. In loamy sandy soils to study the effect of dates application for Biohealth biological fertilizer in (growth stage, elongation stage and growth and elongation stage) + with (0%, 25%, 50%, 75%, 100%) from the mineral fertilizer recommendation for some plant traits in Broad bean (Vicia Faba L.). The experiment was Indicated according to a split-plots system using a randomized complete block design by three replications. A results of the study showed significant superiority in adding biological fertilizer in growth and elongation stage with highest mean of the yield and its components, Amount to (plant pods number 15.45 pod plant-1 and the number of seeds per pods 5.02 seed pod-1 and 100 seed weights 119.17 g and green pods yield 14.29 t ha-1 and seed yield 4.45 t ha-1 and biological yield 11.00 t ha-1). It also significantly outpered the addition of biological fertilizer + with 75% of the recommendation for mineral fertilizer with highest mean of yield and its components, Amount to (plant pods number17.75 pod plant-1 and number of seeds per pods 5.71 seed pod-1 and 100 seed weights 122.72 g and green pods yield 16.21 t ha-1 and seed yield 4.72 t ha-1 and biological yield 11.57 t ha-1). The interactions showed a significant effect on yield characteristics and its studied components, as the interaction treatment exceeded date of adding biological fertilizer + with 75% of fertilizer recommendation at growth and elongation stage highest mean of studied characteristics.
