Aims: This research was carried out in order to guide farmers andresearchers by determining the effect of high plant densities on forageyield of some silage maize genotypes in twin row planting pattern inEastern Mediterranean ecological conditions.Methods and Results: In this study, we evaluated the responses of threesilage maize genotypes (DKC 6589, Cadiz and Bolson) to high plantdensities (9, 10, 11, 12, 13, 14 and 15 plant m-2) in twin row plantingpattern (50:20 cm). Research results showed that forage and hay yieldstended to increase with increasing plant densities up to 14 plants m-2, butdecreased in 15 plants m-2 density. The maximum yields were obtained at14 plants m-2in twin row planting pattern. It was determined that theyields of DKC 6589 and Cadiz genotypes were higher than Bolson. It wasconcluded that with the combination of appropriate genotype and plantdensity, silage yield can be obtained over 7 tons per hectare.Conclusions: Due to the improvement of new maize genotypes continually,it is important to determine the responses of new varieties to agronomicpractices. It is important to determine suitable plant densities in twin rowplanting pattern, which is an alternative practices in maize farming. Theresults of this study indicated that silage maize can be planted in highdensities in twin row planting pattern according to the traditional 70 cmsingle row planting method and the 14 plants m-2 density was the mostsuitable planting density in twin row planting pattern.Significance and Impact of the Study: The study revealed the effect of highplant densities in twin row planting, which is an alternative approach insilage maize production, and has revealed practical data for theMediterranean climate zone. Also, research results reveal importantsource data for farmers and researchers about silage maize farming whoseproduction area is constantly increasing.
