Abstract :

In order to study of effect of cultivator and simultaneous cropping on grain yield and yield components in Varzaneh reign (Esfahan province). A stripe plot arrangement of treatment in a randomized complete block design with three replications was used. Cultivator is considered as a main factor with 3 levels: (C1= not cultivator application, C2= application of cultivator in 30 cm stage of corn, C3= application of cultivator in 60 cm stage of corn) and treatment of simultaneous cropping is considered as sub factor in 5 levels: (S1= Cultivation of pure corn, S2= Cultivation of corn + alfa-alfa, S3= Cultivation of corn + mung bean, S4= Cultivation of corn + cowpea, S5= Cultivation of corn + soybean) were assigned in sub plots. Each sub plot consisted of 4 rows; 6 m long with 60 cm between rows space and 20 cm between plants on the rows and S.C 704 hybrid was used. The result have shown that the effect of cultivator application was significant in stem height, wet stem and leaf weight, grain yield, number of ear in m2. Simultaneous cropping affect on grain yield, number of grain in a row and number of ear in m2. The maximum and minimum of grain yield (1859 and 1559 kg ha-1) were obtained with the not application of cultivator and application of cultivator in 60 cm stage of corn, respectively. In the treatment of Simultaneous cropping as the most and least amount of grain yield with an average 1802 and 1620 kh ha-1, were pure corn cultivation and treatment of Simultaneous cropping (corn + mung bean), respectively.
