The effects of deficit irrigations on yield and yield components of silage corn (Zea mays L.) irrigated with the subsurface drip irrigation method

This study was conducted to determine the effects of deficit irrigations on yield and quality parameters of the corn at Isparta University of Applied Sciences, Faculty of Agricultural, Education, Research and Application Farm in 2017. In this research, six different irrigation subjects (I150, I125, I100, I75, I50 and I25) were applied to silage corn. The experiment was conducted with 3 replications according to randomized block design. Plant height, number of leaves, stalk thickness, first cob height, leaf stalk ratio, cob length, green yield, hay yield, crude protein ratio, crude protein yield, ADF and NDF ratios were determined in this research. According to the analysis of variance, the effect of deficit irrigation application on all investigated features except number of leaves and leaf ratio were statistically significant. The experiment was conducted with 3 replications according to randomized block design. Plant height, number of leaves, stalk thickness, first cob height, leaf stalk ratio, cob length, green yield, hay yield, crude protein ratio, crude protein yield, ADF and NDF ratios were determined.
