interactive effect of genotypes and plant density on peanut yield and yield components

ABSTRACT

This experiment was conducted during the 1998, 1999 and 2000 growing seasons, using three genotypes of peanut IPA2 [runner type], IPA 4 [bunsh type] and IPA 8 [semi erect type] in Raihana Experiment Station at Anna in Alanbbar Province, to study the effect of spacing between rows which were 60,75 and 90 cm and spacing between hills which were 20,35 and 50 cm on yield and yield components of peanut. Results showed that the genotype IPA 2 surpassed the other genotypes in terms of; pods number/plant [71.23] pods weight / plant [103.91 gm], seeds weight / plant [63.33 gm], pods yield [5859 kg / ha] and seed yield [3658 kg/ha], while it did not differ from other genotypes in shelling percentage. The density [90x50] was superior in terms of pods weight / plant [119.26 gm] and seed weight / plant [74.37 gm], meanwhile the density [60x35] surpassed the others densities in terms of pods yield [7041 kg / ha] and seed yield [4255 kg / ha], on the other hand it gave the lowest value of shelling percentage [60.43%], while the density [90x20] gave the highest shelling percentage [64.55%].The study recommends that farmers must grow this crop at the density [90x35] for runner types, [60x35 cm] for bunsh types and the [75x20 cm] for semi erect types
