RESPONSE OF YIELD AND QUALITY OF TWO GROUNDNUT (Arachis hypogaea L.) CULTIVARS TO FOLIAR APPLICATION WITH SOME MICRONUTRIENTS IN NEWLY RECLAIMED SANDY SOIL

Abstract

Two field experiments were carried out during two summer successive seasons (2016 and 2017) at the Production and Research Station, National Research Centre, El- Nubaria Province, El-Beheira Governorate, Egypt. This study aimed to investigate the response of two groundnut (Giza 6 and Gregory) cultivars to some micronutrients foliar application at different growth samples (75 and 90 days after sowing) on growth, yield and yield attributes as well as chemical characters of seeds under reclaimed sandy soil condition. The experimental design of this investigation was laid out in split-plots design with four replicates, where cultivars were assigned in the main plots and micronutrients foliar application with Zn, Mn, and B and their combinations were randomly distributed in the sub-plots. The experimental unit area was 10.5 m2 contained five rows, 60 cm between the rows. Seeds of two groundnut cultivars (Giza 6 and Gregory) at the rate of 40 - 45 kg /faddan. Seeds of peanut cultivars were sown at the mid of May in the two seasons. Micronutrients foliar application were applied twice at 45 and 60 days after sowing. The results obtained can be summarized as follows: 1. Growth characters a. Effect of groundnut cultivars and micronutrients foliar application on growth characters. 1. The data indicate that Giza 6 and Gregory cultivars show highly significant differences at 75 and 90 DAS, however, Giza 6 surpassed Gregory cultivar in most of studied characters at two growth samples except, plant height at 75 DAS. 2. Significantly increases were obtained by micronutrient foliar spraying
