Title
Investigation the effects of density and planting date in corn, sorghum and forage amaranth in Fars province conditions
Authors
Abstract
Abstract
A field study was conducted in 2013 in Fars province to investigate the effects of density and planting date on some traits of 3 forage plants: corn, sorghum and amaranth. The experiment was in a split split plot as randomized complete blocks design with 3 replications. Treatments consisted of plant type ( a1: sorghum, a2:corn, a3:amaranth), density( 66000 plant per ha=b1:25cm, 83000 plant per ha=b2:20cm, 110000plant per ha=b3:15cm) and planting date( c1:22Jun, c2:6Jul, c3:21Jul). The measured parameters were plant dry weight, plant height, stem diameter, grain yield, and 1000-grain weight. The results indicated that there were significant differences among treatments in dry weight, height, stem diameter, grain yield and1000-grain weight. Amaranth had the highest dry weight, stem diameter and grain yield and the lowest valurs were found in sorghum. So experimental results showed that the amaranth at planting date of 6Jul with 66000 plants per ha (25cm) was the best treatment compared with other treatments.
