Determination of the effect of different sowing rates on grain yield and some agromorphological characteristics of popcorn (zea mays everta) in the Çukurova region conditions

This investigation was conducted to determine the effect of different seeding rates (6 cm, 10 cm, 14 cm, 18 cm and 22 cm) on the grain yield and several agromorpholgical characters of popcorn, with a split plot arrangement with three replications in the main crop conditions of Çukurova University, Agricultural Faculty, Field Crops Department Research Fields. The results showed that, different seeding rates afected significantly plant density per area, stem diameter, ear length, number of seeds per ear, ear weight, grain weight per ear, lodging, 1000 grain weight and grain number per ear row. Significant differences were observed for hectoliter weight, unpopped grain rate, grain number per ear row and grain yield between the popcorn varieties. It can be concluded that, In the Çukurova Region conditions the optimum seedin rate was 10-14 cm for maksimum grain yield.
