This research studies the effect of mixing some locally available and cheap materials such as river sand, berlite, saw dust and lime powder with peat-moss as an alternative to pure peat-moss in making the casing layer of mushroom basins. Research in
cludes 14 treatments.
The results show that saw dust and berlite at levels of 10, 20 and 30% with peat-moss contribute in increasing the capacity of the water retention of the casing soil, compared with other treatments, having thus a positive role in increasing the production of the agricultural mushroom significantly in the first week. Saw dust treatment at 20% level recorded (16.33 kg/m2) in the same week, which is the highest production rate in comparison with the control treatment (9.5 kg/m2). Also, the total production of the first and second weeks recorded (26 kg/m2) for the 20% saw dust treatment compared to
(21.5 kg/m2) for the control.
A significant increase has been recorded in the amount of total production in all saw dust treatments, and decline in the rest of the treatments in comparison with the control. The lowest production of mushroom was (8.17 kg/m2) with lime powder treatment at 30% level. The treatments of saw dust levels of 10, 20 and 30% and berlite 20% registered an increase in the net profit and the earning potentials compared to the cost of production.
إكثار الزيتون باستخدام زراعة القمة النامية يهدف هذا البحث لدراسة تاثير عوامل مختلفة في اكثار وتطور العقل المخبرية من الزيتون صنف جلط تحت ظروف الزراعة المخبرية
تعد شجرة الزيتون من أقدم الأشجار التي عرفها الإنسان السوري و مارس
زراعتها من آلاف السنين، و قد تطورت هذه الزراعة تطورًا كبيرًا مذ ذلك الوقت.
تتأثر زراعة الزيتون بمجموعة من العوامل يأتي في مقدمتها الظروف البيئية
الطبيعية ممثلة بالشروط المناخية ( ال
حرارة، الأمطار، الرياح، الرطوبة، الضباب،
البرد و الصقيع) و التربة و أنوعها، إلى جانب العوامل البشرية ممثلة بإعداد الأرض
و الري و التسميد و عمليات خدمة الأشجار.
Sahl Al-Ghab zone is characterized by the availability of natural and human
appropriate conditions for the cultivation of cotton, and it's one of the most desired
agricultural crops for export, in addition to the big need for local textile mills wi
th both of
its public and private sectors, and it's also one of the strategic and social crops. However,
between 2005-2013, cotton cultivation fell back in this region to be replaced mainly by
wheat in addition to other crops, and the main reasons for this decline is that there is no
proportionality between the price of cotton and production costs, as the price of the
kilogram of cotton rose from 31 S.P in 2005 to 100 S.P in 2013, while the price of the liter
of diesel – the main factor in the cultivation of cotton – rose from 25 S.P in 2005 to 60 S.P
in 2013.
Through this research, We knew the reasons for the decrement of cotton cultivation
in Sahl Al-Ghab zone and choosing the wheat and nothing else to replace it, especially that
wheat cultivation didn't achieve better economic returns of cotton.
On the contrary, it had negative results in terms of non-application of the agricultural
cycle and the spread of diseases such as wheat rust disease that spreaded in Sahl Al-Ghab
zone in the last years and which reflected negatively on production.
A successful and detailed in vitro propagation system for rapid
micropropagation of three apple rootstocks: MM ١٠٦, EM ٧ and M ٢٦ has
been developed. Shoot tips and axillary buds excised from field-grown trees
were used as explants, which were surface-disinfected with mercury bichloride,
or with solution of sodium or calcium hypochlorite followed by three rinses
with sterile distilled water.
