  • The Density Of Anopheles arabiensis (Diptera: Culicidae) In Correlation To Malaria Cases and Some Environmental Factors In Three villages around Wad Medani Town

This work aimed at studying the population density of  Anopheles arabiensis and the incidence of malaria, during July–December 2001 and 2002. The study was conducted in three villages, namely Kereba, Barakat and Hantoub. The mean temperature and amount of rain fall were also recorded during this study.

          The results showed that the species of Anopheles arabiensis (Larvae and Adults) was recorded in all villages. The numbers recorded for this vector species was higher during September, in Kereba and Hantoub villages and during August in Barakat village than during the other months, during 2001. In 2002, the means recorded for this species were higher during September and October in Kereba and during August and September in Barakat and Hantoub than during other months. The species was not recorded during November and December 2002 in all villages. The overall mean number of the vector recorded in all villages was higher in 2001 than in 2002.

          The number of malaria cases recorded in all villages were highly correlated with the number of vectors recorded and with the environmental factors (mean temperature and the amount of rain fall), During 2001, the amount of rainfall was high and this may have led to the increase of the breeding sites, and hence, the malaria cases recorded.

          During both years the numbers of vectors and of the resulting malaria cases were higher in Kereba and Barakat villages, than in Hantoub village.

  • The Developmental Period Of Two Species Of Anopheles Mosquitoes (Diptera: Culicidae) From three villages around Wad Medani Twon

This work aimed at studying the developmental periods of the different stages of  the vector under laboratory conditions. The study was conducted in three villages around Wad Medani, namely Kereba, Barakat and Hantoub.      The research was targeting three species of the vector in all three villages viz. Anopheles arabiensis and  A. pharoensis. The tests was conducted in 2001.

          The oviposition period was longer in A. arabiensis and A. pharoensis (3.0 and 3.2 days, respectively). The oviposition rates were 214.6 and 239.6 eggs/female/day, respectively. Consequently the mean fecundity was higher for those two vector species (762.0 and 760.3 eggs/female).

          Under laboratory conditions the developmental period of the eggs, larvae, pupae, adult stages and total life cycle for the two species, ranged 2.0-2.5, 5.5 – 6.0, 2.0 – 2.3, 15.5 – 19.5 and 25.0 – 30.0 days, respectively

  • THE ROLE OF URBAN AGRICULTURE IN SELF-SUFFICIENCY OF FOOD: THE CASE OF KHARTOUM STATE
  1. Conclusion

It appears from this the case study that urban farming provides solutions to the multifaceted problem caused by the rapid migration. Thus, the labor intensive farming alongside the banks of the Blue and White Niles as well as the banks of the River Nile provide many opportunities for the job seekers unskilled migrants from the rural areas. Also, the vast business activities of marketing of the crops produced within the urban agriculture, as well as the marketing of inputs consumed in urban agriculture provide unlimited job opportunities. In addition, the small scale labor intensive urban agriculture is capable of producing increased amounts of food products that are needed in the urban centers.

  • Determination of crop coefficients, water requirements and water productivity for maize (Zea mays L.) under central Gezira clay soil conditions, Sudan

ABSTRACT

   Development of site specific crop coefficients (Kc) helps tremendously in irrigation management and furthermore provides precise water application in the region. This study was conducted at the Experimental Farm, University of Gezira, during seasons 2014/15 (first season) and 2015/16 (second season) to estimate crop coefficients (Kc), crop water requirements (CWR) and water productivity (WP) of maize cultivar Hudaiba2. The reference evapotranspiration (ETo) was calculated using the FAO computer program (CROPWAT). Actual crop evapotranspiration (ETc) was estimated by the gravimetric method. Crop coefficients were derived from the relationship between reference evapotranspiration and actual crop evapotranspiration.  The results showed that crop coefficients values for maize were 0.51 and 0.47 for initial stages, 1.26, and 1.15 for the mid stages and then decreased gradually to 0.53 and 0.42 for the late stages, in the first and second season; respectively. The peak Kc occurred during the period 60 to 70 days after sowing (DAS), coinciding with the maximum ETc of 6.75 mm/day at the mid-season stage for maize. The crop consumptive water use of maize were 491 mm (4910 m3/ha) for the total growing period. The mean yield of maize was 4285kg/ha and the crop water productivity was 0.58 kg/m3.

الخلاصة

 

  ان حساب معامل المحصول (Kc)  يساعد بشكل كبير فى ادارة مياه الرى وتطبيق دقيق للماء المضاف فى المنطقة. أجريت هذه الدراسة بمزرعة جامعة الجزيرة – كلية العلوم الزراعية بولاية الجزيرة في موسمين 2014/ 2015م و 2015/2016م. بهدف حساب معامل المحصول (Kc)  والاحتياج المائى (CWR) وكفاءة استخدام المياه (WP) لمحصول الذرة الشامى  (صنف حديبة 2 (. تم حساب البخرنتح المرجعي (ETo) باستخدام برنامج CROPWAT كما تم حساب البخر نتح للمحصول(ETc) باستخدام الطريقة الوزنية ومن ثم تم تقدير معامل المحصول (Kc) من العلاقة بين البخرنتح المرجعى والبخرنتح للمحصول. أوضحت النتائج أن معامل المحصول  يبدأ من 0.36 و 0,41 فى المراحل الأولية من عمر المحصول حتى يصل إلى أعلى قيمة له 1,26 و 1,30 ومن ثم يتناقص تدريجيا إلى أن يصل أدنى قيمة له 0,44 و 0,47 فى الطور النهائي لمحصول الذرة الشامى للموسم الاول والثانى على التوالي. أعلى قيمة لمعامل محصول الذرة الشامى كانت بعد مرور 60 و 70 يوم من تاريخ الزراعة وهى 6.53 و 6.98 ملم/يوم. الاستهلاك المائي خلال الموسم بلغ 448 و 380 ملم و كانت الإنتاجية 4650 و 3920 كجم/هكتار على التوالى أما  متوسط كفاءة استخدام المحصول لمياه الري فكانت0.58  كجم/م3. لهذا فان قيم معامل المحصول يجب ان تستخدم لحساب كمية الماء المضاف لزيادة الانتاجية وكفاءة استخدام المياه.
