Abstract

Considering importance of baby corn, the study was consisted of sowing date (14th June, 3th July and 24th July) as main Plots and plant densities (6.5, 8.5 and 10.5. plant m-2) as sub Plots and two harvest methods (baby corn, as first harvest sweet corn and next ear as baby corn) on Growth parameter and yield of baby corn (Zea mays L. Var SC403su) in agricultural Research Center and Natural Resources of Khorasan Razavi Province, Mashhad on 2009. The experiment was carried out in a factorial split plot design based on randomized completely block design with 4 replications. The results showed the highest plant height on sowing date 3thJuly with average 168.6 cm. Also the highest standard ear percentage that one of the important factors for food manufactory had on sowing date 24th July with plant density 10.5 plants plant m-2, by harvesting method baby corn with 63.9 percentages. Also The results showed the highest substandard ear percentage of baby corn was belonged to sowing date 24th July with 8.5 plant m-2, by harvesting method (baby corn sweet corn) with 74.6%. The highest harvest ear index was belonged to sowing date14thJune, by harvesting method (baby corn sweet corn) with 35.29 percentages. Therefore, sowing date 3thJuly for forage production with average 4 kg m-2 by harvesting method baby corn are recommended for lateral produce production. Considering to Mashhad weather conditions, producing the highest and best standard ear percentage, density, 10.5 plants per square meter and 24th July planting is recommended.
