Effect of Npk-Levels on Productivity and Seed Quality of Some Groundnut Genotypes under Newly Reclaimed Sandy Soils Conditions

Abstract

At the Station of Experimental Research in Ismailia, ARC, Egypt, in 2014 season a field experiment was conducted, and the same field experiment was replicate in 2015 seasons to find out the influence of NPK-rates on productivity and seed quality of some groundnut genotypes lower newly reclaimed sandy soils conditions in Ismailia Governorate. In design of strip-plot, the experiment was carried out using four replications. Results showed that Strain 13 among the studies genotypes had the highest values of plant height and crude protein percentage in seeds. While, Gregory cultivar recorded the highest values of oil percentage in seeds. However Strain 281 significantly surpassed other studied genotypes and recorded the highest means of other considered traits. In each seasons, plants of groundnut were mineral fertilizing by 45.0 + 30.0 + 24.0 kg NPK per feddan, respectively (100 % of the recommended doses) surpassed other studied NPK-levels under study and produced the highest means of every one of considered means, followed by using 80 % and then 60 % of the recommended doses. It could be recommended that mineral fertilizing groundnut Strain 281 or Strain 10 or Gregory cultivar with 45.0 kg N + 30.0 kg P 2 O 5 + 24.0 K 2 O per feddan to recorded highest productivity under newly reclaimed sandy soils conditions in Ismailia Governorate.

Influence of Foliar Application of Some Micronutrients Levels on Growth, Yield, Yield Attributes, Micronutrient Content and Fatty Acids of Two Groundnut (Arachis hypogaea L.) varieties

“…This may be due to genetic factors formed by the varieties used moreover the interaction between varieties and environment. These finding are in a good line with Seadh et al (2017), Abdel-Motagally et al (2016) and Mohammed et al (2018) showed highly significant difference among groundnut genotypeby-season interaction for most of the traits studied.…”
