The experiment design was R .C .B .D.

where treatments were in split - split plots arrangement replicated three times the results showed that there were significant effect all factors on all Characteristics under the study in such that the spacing 30 cm and the cultivates IPA 2052 gave the highest grain yield (172.5 and 165.6g/plant respectively).

Also the treatments combination of (30cm * IPA 2052) gave the highest yield (217.75 g/plant).
