Title

EFFECT OF SOWING DATE AND PLANT DENSITY ON YIELD AND YIELD ITS AND SOME AGRONOMIC CHARACTERISTICS OF BABY CORN CV. KSC403 SU

Pages

  449-463

Abstract

 This study was conducted to evaluate effect of different summer SOWING DATEs and plant densities on yield and yield components and some agronomic characteristics of BABY CORN cv. KSC403 su (Zea mays L.) in Agricultural and Natural Resources Research Center of Khorasan Razavi Province, Mashhad, Iran in 2008 cropping season. This experiment was carried out using split plot arrangements in a RCBD with four replications. The SOWING DATE (14th June, 3th July, 24th July) and plant densities (65000, 85000 and 105000 plant. ha-1) were assigned in main and sub plots, respectively. Results showed significant differences between different SOWING DATE for palnt height, dehusked and husked BABY CORN yield, ear height, stem diameter, ear length, ear diameter, standard and sub-standard dehusked BABY CORN yield, standard and sub-standard ear percentage and fresh forge yield. The highest BABY CORN yield of 13240 kg ha-1 obtained in 24th July SOWING DATE. Delay in SOWING DATE led to increase of growth period and suitable weather (cooler temperatures) at anthesis, therefore, ear yield increased, but ear length decreased and ear diameter increased. Ear marketing decreased, not only for fresh consumption but also for industry. PLANT DENSITY had significant effect on stem diameter, no. of ear/plant, plant height, dehusked BABY CORN yield, fresh forage yield, standard and sub-standard dehusked BABY CORN yield and harvest index. The highest BABY CORN yield was harvested from the highest PLANT DENSITY (722 kg ha-1). Finally, the interaction of SOWING DATE × PLANT DENSITY was significant only for standard ear percentage (p<0.05). SOWING DATE 14th June with planting density of 105000 plants ha-1 was determined as suitable package for BABY CORN production and marketing in Mashhad region.
