Evaluation of some peanut genotypes under two planting methods and different fertilization levels

Abstract EN

A field experiment was carried out at Arab Elawamr Research Station Farm, Oil Crops Department, Assiut Governorate, Agriculture Research Center (ARC), Egypt, during the summer of 2013 and 2014 seasons.

This work aimd to study the evaluation of some peanut genotypes under two planting methods and different fertilization levels cultivated in sandy calcareous soil.

The experiment was laid out in randomized complete block design (RCBD) using split-split-plot arrangement with three replicates.

The two planting methods (Farming on the furrows 60 cm apart and Farming on the terraces each terrace contain two rows 60 cm apart) were assigned to the main plots.

The sub – plots were allocated to three peanut genotypes (Giza 6, Sohag 104 and Sohag 110), while the three fertilization combination (20 m3 organic/ fed, 10 m3 organic / fed with 50% of the recommended NPK and 100% recommended NPK ) were placed on sub-subplots.

The results show that the studied planting methods had a significant effect on most studied traits.

Here too, studied genotypes varied significantly in all studied traits except seed and oil yields in the second season.

Moreover, all studied traits reacted significantly to studied fertilization levels in the two growing seasons.

Also, cultivated Giza 6 genotype by terraces method (M2) received F2 fertilization treatment gained the highest mean values (640.0 and 313.7 kg fed-1 ) of seed and oil yields, respectively, in the first season while in the second season the highest mean values (818.0 and 396.7 kg fed-1 ) for seed and oil yields, respectively, were obtained from cultivated Sohage 110 genotype using furrow(M1) planting methods subjected to F2 fertilization treatment.
