| Abstract | ||
| To investigate the evaluation of the efficiency of spraying with seaweed extracts, chemical pesticides and dates spray on some physical, chemical and productive properties of date palm cv. khastawi, a field experiment was conducted during of 2018 in one of the private palm orchards infected with dust mite (Oligoneychus afrasaiticus) in the village of Al-Bu'ali al-Jassim, northwest of Ramadi, RCBD with three replications as factorial at two factors was used. first factor was sprayed with 2.5 ml L-1 seaweed extract (Stimplex), Two types of pesticides Koffex and Miteclean were sprayed with 1ml L-1, seconed was spraying dates (15 / 4, 15 / 6). The results showed significant differences between the two dates in properties under study. The results showed that the treatment of pesticide Miteclean with seaweed extract was significantly higher in the two date in properties, fruit length (36.58 mm), the diameter of the fruit (24.17 mm), kernel weight (1.05 gm) and the diameter of the kernel (8.89 mm), and scrod the highest percentages of total sugars (27.91%) and percentage of N (0.98%), P (0.18%), K (1.10%) and total chlorophyll in the leaves (0.95 mg. gm-1). as well as of this study showed an increase in the productive Features, (shark weight, number of fruits by shark 1 and the total yield of date plam), the highest values were scored which were 230.10 gm, 19.63 fruit. shark-1 and 157.04 kg respectively, and reduced percentage of infestation with dust mite, which achieved value 0.00% compared with pesticide alone (7.00%). Therefore it can be concluded that the application of seaweed extracts and acaricides was the most efficient in properties under study and the positive consequences on total yield and yield components of date plam. | ||
