تهدف هذه الدراسة إلى التعرف على الغطاء النباتي بمنطقة قبر جيرة بالجبل الأخضر \"ليبيا\" وذلك من أجل المساعدة في إيجاد قاعدة بيانات حول الأنواع المنتشرة بالمنطقة تساعد المختصين في وضع برنامج مناسب للمحافظة على هذه الأنواع، حيث تم اختيار 40 موقع لحصر أنواع النباتات الزهرية المنتشرة بها. أوضحت نتائج الدراسة أن هناك 74 نوعا من النباتات الزهرية تنتمي إلى 58 جنسا موزعة على 22 فصيلة منها 19 فصيلة من ذوات الفلقتين و 3فصائل من ذوات الفلقة الواحدة. وتعتبر هذه الدراسة أول دراسة تجرى على هذه المنطقة والتي تتميز بوجود نشاطات بشرية كبيرة تتمثل في الزراعة المطرية والرعي والتوسع العمراني حيث يتعرض فيها الغطاء النباتي لضغوطات كبيرة نتيجة لهذه الأنشطة.

Damazin, in Eastern Sudan, is a centre for rainfed agriculture with a cultivable area estimated at 3,000,000 feddans (1,260,000 ha). Both mechanized and traditional manual farming methods are presently adopted in the area. A dominant implement was a seed spreader pulled by a tractor from the models that prevailed during early years of the last quarter of the twentieth century. The combination was found difficult to transport through narrow lanes to small farms scattered in a characteristically mountainous area. Conventional manual farming with traditional hand tools was labour intensive and needs indigenous efforts for improvement through the development and introduction of better tools that combine more than one operation. A hand operated planter developed at the faculty of agricultural technologies of the University of Al Neelain could provide a positive step in that direction. The planter comprised a seed hopper, a metering mechanism with a seed delivery tube, a slot opener, and a seed coverer. The implement was simple to fabricate, to operate and to transport..

A field experiment was conducted for two consecutive rainy seasons (2008/09 and 2009/10) in the Experimental Farm of the Faculty of Agriculture at Abu Naama, University of Sinnar to study the response of Sorghum bicolor L. Variety \"Wad Ahmed\" to sowing date and seed rate under rainfed conditions. The experiment was laid out in a factorial randomized complete block design with four replications, the treatments consisted of three different sowing dates (5/July, 20/July and 5/August) and three different seed rates (2Kg/Fed., 3Kg/Fed. and 4Kg/Fed.). The results showed that, sowing date and seed rate showed significant effect on number of tillers/plant, number of heads/plant, grain yield and 1000-grain weight in both seasons. The interaction between sowing date and seed rate showed significant effect in number of tillers/plant and number of heads/ plant in both seasons. Moreover, the interaction showed significant effect in grain yield in the second season only and 1000-grain weight in the first season only. The best sorghum grain yield was observed on maximum seed rate with early sowing date, and low seed rate with mid and late sowing date

Two experiments were conducted at Abunaama area in season 2000-2001 to investigate the fertilizing effect of different neem preparations on growth and yield of rainfed groundnut ( Arachis hypogaea). The treatments were: Neem leaves powder (NLP) at 50 and 100kgfed; neem seed cake powder(NSCP) at 25 and 50kgfed, neem seed Kernel powder (NSKP) at 25 and 50 kgfed and a control treatment. This was done in a groundnut field as soil incorporation before planting, using a Randomized Complete Block design (RCBD) with four replicates. Shoot dry weight (SDW) in g. was determined three times at monthly intervals, starting at 30 days after germination. Yield (pod) was determined at maturity. Results revealed that NSCP at 50Kgfed and NLP at 100Kgfed slightly increased shoot dry weight, but increased pod dramatically at the two sites. The increase ranged from 87% (NSKP 25 kg/fed.) to 144% (NLP 100kg/fed.) at the college farm and from 3% (NSKP 25kg /fed.) to 188% (NSCP 50kg /fed.) at Kenaf farm
