بررسي تاثير الگوهاي مختلف كاشت و تراكم بوته بر عملكرد و اجزاء عملكرد ذرت دانه اي (ZES MAYS L. HYBRID K.S.C.704) در شرايط آب و هوائي اهواز

Assessment of Planting Patterns and Plant Density on Yield and Yield Components of corn (Zea Mays 1,. Hybrid K.S.c.704) under Ahwaz climatic Conditions

The objective of this study was to study the effect of pL.:J.nllng: patterns and plant density on yield and yield componens of corn (Hybrid K,S.C 704). The research ʹvas carried out in Agricultural Research Station of Azad University in Ahwaz. The trial was arranged In factorial with randomized complete hlock design with three rcnhcations. Om: factor W.1S planting patterns (one-row and two-row planting on a ridge] and another factor was three levels of plant distances on each row (25, 30 and 35 centimeters). The findings in the present study showed that planting patterns had sigmrlcant cffccts on the number of cubs per square and the number of seeds on one row of cub, hut the other yield componentvʹere not statistically significant. Effect of planung patterns had significant effect 1111 gram yield. The maximum and the minimum grain yield product bclouged to two-row planting (2655 kg! ha) and one-row planting {2411 kg/ haj respcctively. with respect to the effect of plant density for yield components, the results showed that the number of seeds per row on cubs was highly affected hy plant density but in Lase of other yield components the result was not significant. furthermore, the grain yield indicates thai the effect of plant density on grain yield was varidable in which the hlghesl and the lowest grain yield were obtained for 25 and 35 centimeters seed distances (2671 kg.ʹlm and 21.14 kg/ha respectively).
