Response of growth characters, yield and yield attributes of groundnut (ARACHIS HYPOGAEA L.) cultivars to some micronutrients foliar spraying application

Abstract

Two field experiments were carried out during two successive summer seasons (2015 and 2016) at the Production and Research Station, National Research Centre, El-Nubaria Province, El-Beheira Governorate, Egypt to investigate the response of two groundnut (Giza 6 and Gregory) varieties to some micronutrients foliar application i.e. Zinc, Manganese and Boron and their interaction with different growth stages on yield, yield attributes and some chemical traits of groundnut seeds under reclaimed sandy soil condition. Cultivar Giza 6 showed high value of growth characters compared with Gregory variety for all traits except plant height at 75 DAS. On the other hand, data illustrate that combination of Zn+ Mn+ B surpassed over all treatments and control. The interaction effect between groundnut varieties and micronutrient foliar application revealed a high significant difference for all studied traits. Yield attributes (number of pods plant-1, number of seed plant-1, weight of pods plant-1 and seed weight plant-1 and 100 seed weight) were effected significantly due to foliar spraying with micronutrient treatments. The data recorded that Giza 6 show high performance for all studied traits comparing with Gregory. Mixture of (Zn+Mn+B) recorded high value comparing with dual effect of (Zn+Mn, Zn+B and Mn+B) also single effect (Zn, Mn and B) for yield components. Influence of interaction revealed that Giza 6 variety recorded high performance for all yield characters except harvest index and oil %. Therefore, Giza 6 variety responded positively to treatments with Zn 400 ppm +Mn 400 ppm+ B 0.06 as boric acid for pod, seed, straw, biological, oil and protein yield faddan-1.
