Title

EFFECT OF ROW SPACING AND PLANT POPULATION ON GROWTH AND DEVELOPMENT GRAIN CORN IN DAMGHAN PROVINCE

Pages

  45-57

Abstract

 The experiment was condncted at Azad University of Damghan Iran in 1996 by using split plot desigan based on randomized complete bloch with three replication. The main plost were two levels of row spacing (60 and 75 cm) and sub plots were the factorial of two corn hybrids single cross 704 (late maturity) and three way cross 647 (medium maturity) and three levels of plant population (75,90 and 105 thousand plant/he). The differences between hybrids for the plant characters such as, the number of days from planting at pollination and physiological maturity, plant height, dry weight of leaf and stem at pollination and physiological maturity, number of node, corn node and corn sheath at the stage of pollination and dry weight of cob, ear, male inflorescence and whole plant at pollination and physiological maturity were significant. Among characters under study the stem dry weight at physiological maturity, stem and leaf dry weight at pollination and the male inflorescence initiation and the whole plant dry weight at pollination and physiological maturity and also the grain yield were all affected by row spacing. The number of days from planting to pollination and plant height, stem diameter, dry weight of male inflorescence and whole plant dry weight at pollination and physiological maturity, dry weight of stem and corn leaf at pollination, and pollination maturity dry weight of cob at pollination, dry weight of cob, corn sheath and ear, at physiological maturity and also the grain yield were affected by plant population. It could be concluded that the 60 cm row spacing with 90 thousand plants per hectare and also row spacing of 60 cm with 105 thousand plants per hectare are the best combination for single cross 704 and three-way cross 647, respectively
