RESPONSE OF SWEET CORN TO BACTERIAL BIOFERTILIZERS AND SPRAYING WITH MINERAL NUTRIENTS

Abstract

This study was aimed to investigate response of two sweet corn hybrids to bacterial biofertilizers and spraying with Mg+2 and Ca+2 and their impact on the Yield during Spring season 2022, CASH seeds (H1) and ROI SOLEIL seeds (H2) were planted in pots, when they reached 2-3 leaves treated with four treatments which included without biofertilizer (B0), with Azospirillum brasilense (B1) with Pseudomonas fluorescens (B2) and the interaction with Azospirillum brasilense and Pseudomonas fluorescens (B3) then transferrd to the field, and sprayed the seedling after 20 and 30 days of seedling with three concentrations which included control, without spraying (N0), spraying with Mg++ and Ca++ with concentration of 25 mg L-1 (N1) and 50 mg L-1 each elements (N2), The experiment was carried out according to RCBD with in split plot arrangement. The results showed that hybrid H2, the treatment of bacterial biofertilizers B3 and the foliar spraying of Magnesium and Calcium N2 had significant effect in all studied traits. H2B3N1 had significant effect in plant height and the number of leaves, H2B3N2 had significant effect in leaf area and leaf area index and plant dry weight, H2B1N2 had significant effect in total chlorophyll concentration in leaves, It was found that the study factors and their interactions had a role in increasing the vegetative growth indicators of the sweet corn hybrids.
