Effects of plant populations and nitrogen doses on fresh ear yield and yield components of sweet corn (Zea mays saccharata Sturt.) grown under Bursa conditions.

摘要: This research was carried out under Bursa conditions in 1995 and 1997. In this study, the effects of plant population nitrogen doses on fresh ear yield some components hybrid variety Merit were investigated. Row spacing constant distances within rows 10, 15, 20, 25, 30 35 cm used. Five (0, 100, 200, 300 400 kg N/ha) also applied. According to mean two year results, found be statistically significant height, diameter, seed number ear, weight, ears each yield. Plant x level interaction significant. It shown that a distance 21.4 (71900 plants/ha), dose 280 kg/ha suitable combination for maximum according regression analysis.
