effects of relay cropping date, plant density and harvest method on growth and yield of baby corn cv. golden kernel

considering importance of baby corn as a new food, this study was conducted to evaluate effect of different sowing date; planting density and harvest methods on growth and yield of baby corn ksc403su varieties in agricultural research center and natural resources of khorasan razavi province during on 2007-2008. was considered at three levels of sowing date (14th  june, 3th  july, 24th july) as main plots and planting density (65, 85 and 105 plant. ha-1) and two harvest methods (baby corn ,sweet corn and together) as sub factor. these experiments were considered out in a factorial split plot design based on rcbd with four replications. the results showed significant differences between different sowing date for number of leaf/plant, number of leaf above ear, stem diameter, ear length, no. of ear /plant, dehusked baby corn yield. the highest dehusked baby corn yield with 3051 kg ha-1 was belonged to 24 july sowing date on harvest method baby corn. the plant density had significant effects only for stem diameter, dehusked baby corn yield and forge yield. in addition, the harvest method had significant effects on number of leaf above ear, no. of ear /plant, dehusked baby corn yield, fresh forge yield and ear and plant harvest index. therefore, sowing date 14 june and with planting density (105000 plants / hac), is recommended for maximum and better standard ear marketing.
