Abstract

To study SOWING DATE, and rate of NITROGEN effect on yield and YIELD COMPONENTs of OILSEED RADISH (Raphanussativus L.) this experiment has been done in KARAJ. This experiment carried out in strip plot in the basis of randomized complete block design with 3 replications. In this design, the vertical Plots were in three levels, 20 July, 8 August, and 6 September and horizontal plots with various rates of NITROGEN had 4 levels,0, 60, 100, and 140 kg.ha-1 in pure NITROGEN from source of urea. The results of measurements of yield and YIELD COMPONENTs of plant show that the SOWING DATE in 1% probability has a significant effect on shoot dry weight and in 5% probability it has, significant effect on leaf dry weight. And even has a significant effect on weight of inflorescence, root too shoot ration and vegetative to reproductive ration. This effect was too much so that 8 August SOWING DATE from other treats has the most weight of shoot dry that we measured leaf and vegetative to reproductive ration as 383.584 , 220.932, 4.702 respectively that leaf dry weight with SOWING DATE of 6 September state in a statistic group. The most ration of root to shoot dry weight was relative to 6 September SOWING DATE with 0.560 gr.m-2. The NITROGEN factor on 5% probability level has just effect on dry material of inflorescence so that the most rate was belongs to treat control and 100 kg.ha-1 NITROGEN. Altogether, The reproductive members have increased with NITROGEN application. In general, the maximum rate of dry material of whole plant belonged to 8 August SOWING DATE with 523.712 gr.m-2 among NITROGEN’s treats, either applying 60 kg.ha-1 NITROGEN, 489.102 gr.m-2 and spending NITROGEN up to 140 kg.ha-1 level, 488.160 gr.m-2 was added to dry material of whole plant that of course these factors didn’t showed a significant effect.
