Evaluation of variety and plant density on grain yield, number of seed per cob and 100 grain weight in maize (Zea mays L.)
Abstract
Maize is ranked third among cereal crops after wheat and rice. Maize is used as staple food. Maize is also used as feed for livestock. Planting density plays an important role in achieving high productivity per unit area. Plant density is invariably linked with yield, the more plant stands there are up to a certain limit, the higher the expected yield. The experiment was conducted at the Research Station in sohrabad khash. The field experiment was laid out in randomized complete block design with factorial design with three replications. Treatments included variety (v1: s.c 704, v2: s.c 540, v3:sc 301) and plant density consisted of D1: 6.5 plant/m2, D2: 7.5 plant/m2, D3: 8.5 plant/m2 and D4: 9.5 plant/m2. Analysis of variance showed that the effect of variety on characteristics was significant.
