The Effect of some Agricultural Treatments on number of the Morphological and productive Characteristics of the coriander p

Abstract

 The research was carried out at kafar Sandal Research Station in Idlib Governorate, during the (2018-2019) agricultural season. The experiment was carried out by applying the design of Split random sectors, Where the seeds of coriander were planted in two different dates a month apart between the first sowing date and the other. To specify more, they are respectively in the first of February, and the first of March. And during these two dates, two rates of triple super phosphate were applied 46% with three replications per treatment. In fact, the two rates were (150,120 kg\h), in addition to the treatment of witness (0) kg\h. The research results showed that delaying the date of planting resulted in the early date of blooming and ripening, and in a significant increase in the number of branches on the plant. Both of increasing the rates of phosphate fertilizers, up to (150 kg'\h), and delaying the sowing date gave the highest number of branches\plant, flowering inflorscences \plant, and a significant increase in the weight and number of the seeds in the plant. It is important to mention that such results appeared when adding (180 kg\h) of the super phosphate fertilizer per hectare. As the number of seeds in the plant reached (232.7) seeds\plant. In fact, this number is considered to be an increase of (49.3) seeds\plant over the general average. As a matter of fact, the early cultivation date, with the use of the phosphate fertilization at an average of (150 kg\h), also led to a significant increase in the height of the Coriander plant, the number of plants per unit area, and an increase in the seed yield, as the production reached (969 kg\h).
