The Effects of Plant Density and Organic Fertilizer on Growth and Yield of Sweet Corn (Zea mays L. var. saccharata Sturt)
Öz
The present study was conducted to investigate the effect of plant density (A1:80000, A2:120000, and A3:160000 plant ha-1) and organic fertilizer (B1:0 and B2:25 ton ha-1) on growth and yield of sweet corn (Zea mays L. var. saccharate, Sturt cv. Succar, F1) in a private farm in Qushtapa, 30 km far from the center of Erbil in Iraq, during the spring seasons in 2017 and 2018 years. The experiment was designed in a factorial randomized complete block design (RCBD) with three replications. The traits studied were: plant height (cm), number of leaves, number of branches, chlorophyll content, leaf areas (m2), dry matter content, cob length (cm), number of seed per row, com diameter (cm), number of cob per plant and number of row per con, seed number per cob, fresh seed yield(ton ha-1) and fresh cob yield (ton ha-1). The results of the experiment revealed that plant density and organic fertilization and their interaction were significant in almost all traits in both years.
