| Abstract | ||
| A field experiment was conducted during the summer season of 2014, in rice research station in Al Meshkhab of the agricultural research department (AL Najaf Province) in order to study the effect of five planting dates )6/1 , 6/15 , 7/1 , 7/15 , 8/1) in the yield and yield components for five rice varieties (Anber 33 , Yasmin , Forat 1 , Anber al Baraka , Bhoth 1). Use Split plot design with randomized complete block design RCBD with three replication , was usedThe planting date represented the main plot, while the varieties referrd to sub plot which is the most important factor Data analyzed statistically by using the method of analysis of variance and the means tested by the test of less significant difference (LSD). The results showed, thatAnber al-Baraka significantly superior in number of panicles per area unit , and the economical and biological yields with means 265.4 panicle.m-2 , 4.632 ton.ha-1 , and 13.99 tan.ha-1 respectively, The planting date 1/6 was superior in number of panicles per area unit, number of grain per panicle and the economical and biological yields with means 272.3 panicle.m-2 , 99.86 grain.panicle-1 , 6.054 tan.ha-1 and 15.71 ton.ha-1 respectively.The interaction between plouting dates (traetments) found that Forat 1 cultivated in 1/6 in the percentage of non-fertile and the economical and biological yields with means 13.26% , 8.651 ton.ha-1 and 18.70 ton.ha-1 respectively.The study concluded that chosing the approprial plating date and the variety has an effect in the yield and yield components for rice crop . | ||
