Abstract

 One potato cultivar (Diamant) was grown for two consecutive seasons (2004/5 -2005/6) at Darmali Irrigated Karu Soils (clay 42-52%) to test different correlations between fertilizer, yield and some yield components (crop- ground cover of the canbay and number of stolons/plant). Twenty out of 72 experimental plot unit, were arranged in split plot design and considered for correlation analysis to obtain different correlation coefficients between the above mentioned traits .Results revealed that in all tested traits, correlations were positive in various degrees, however, in some of them was not significant. Fertilizer showed highly significant and positive correlation with crop cover and yield. With regard to stolons, the relation though positive, was not significant in the two seasons. Yield- crop cover correlations were significantly positive for the two seasons, while, yield –stolon correlations were positive but only significant for season 2004/5 .Crop cover-stolons correlations were not significant, though positive for the two seasons.

  

الإرتباط بين التسميد و الإنتاجية وبعض مكوناتها لمحصول البطاطس المروى باراضي الكرو في ولاية نهر النيل, السودان

اجريت تجربة علي محصول البطاطس الصنف دايمونت لموسمين متتاليين(2004- 2005 و 2005-2006) تحت الري في اراضي الكرو بدارمالي لدراسة الإرتباط بين التسميد والإنتاجية وبعض مكوناتها (نسبة تغطية النبات وعدد السيقان الارضية). فقط 20 من72 وحدة تجريبية اجريت وفق تصميم القطع المنشقة هي التي استخدمت لتحليل معامل الإرتباط بين التسميد والخواص المقاسة المذكورة. اثبتت النتائج أن معامل ألإرتباط لكل القياسات المذكورة إيجابي وفق مستويات مختلفة رغم أنه لم يكن معنويا في بعض منها. بالنسبة للتسميد فقد أوضحت الدراسة إرتباطه العالي والمعنوي مع ألإنتاجية ونسبة تغطية النبات ولكن لعدد السيقان ألأرضية فقد كانت النتيجة معنوية فقط لموسم واحد. ألإرتباط بين ألإنتاجية ونسبة التغطية كان معنويا للموسمين بينما كان معنويا في موسم واحد مع عدد السيقان ألأرضية. الإرتباط بين نسبة التغطية والسيقان الأرضية لم يكن معنويا رغم أنه كان إجابيا في الموسمين.

A field experiment was conducted for two consecutive seasons (2004/5 and 2005/6) at Krikur farm, Dar Mali, Naher El Neel State, Northern Sudan. The experiment was laid out in a splitsplit plot design with four replications, to study the response of potato (Solanum tuberosum) to different cultural practices. Treatments included three row spacings (70, 80 and 90 cm) assigned as main plot, sowing depth (10, 15 and 20 cm) as subplots and earthing up (once or twice) as sub-sub plots. Parameters measured were days to emergence, number of stems, crop cover, number of stolons/ hill, yield (t ha-1), dry matter content and sugar content of the tubers. The results indicated that number of days to emergence and number of stems were unaffected by either of the treatments applied. Increasing ridge spacing decreased significantly crop cover and tuber yield, and increased dry matter content of the tubers, but did not affect sugar content. Increasing sowing depth increased significantly the number of stolons, tuber yield, dry matter and sugar content of the tubers. Reridging twice (earthing up) had no significant effect on any of the tested parameters.

In Sudan, due to a short growing season, potato has to be sown in early November. With climate change, temperatures at this time are high, causing  seed decay. An experiment in a split-plot design with three replications was conducted for two growing seasons (2008/9 and 2009/10) to examine the effects  of seed size and seed treatment with disinfectants on the growth and yield of potato planted during early November. Seed tuber size (<35 mm, 3555 mm  and splitted >55 mm) was assigned to the main plots, while treatment with disinfectants was assigned to the sub-plots. Cupric sulphate solution of 1.5%, commercial Clorox (5% sodium hypochlorite) 2% conc. and tap water (as control) were used as disinfectants by dipping potato tubers in them for 2030 minutes. Parameters measured were percent emergence, number of stems per hill, crop canopy cover, severeness of leaf blight infection, number of tubers per  plant and weight of tubers (g/plant). Results revealed that germination and crop cover were significantly reduced and leaf blight was increased in splitted largesized seed tubers. Seed treatment increased significantly the number of tubers and tuber weight per plant. Number of stems per hill was not affected by either of the experimental treatments. The highest tuber weight per plant was obtained by small-sized seed treated with Clorox in the first season (414 g) and mediumsized Clorox-treated seed in the second season (381 g).

Abstract: Fertilization experiment was conducted in Krikur farm at Dar Mali, Naher Elneel State, Sudan in season2004/5, 2005/6 to evaluate the response of different fertilizer types and levels on the yield and qualities of ware potatoes. Three levels of ADB foliar fertilizer (control, spraying every 14 days and spraying every 7 days) with concentration of 30 ml dissolved in 10 liters of water, were the main plots and six levels of urea or a combination of urea and chicken manure (0N/ha, 180kgN/ha, 270kgN/ha, 360kgN/ha, 180kgN/h+10m3 chicken manure and 180kgN/ha+20m3 chicken manure) were the sub plots. Parameters measured were days to emergence, number of stems, crop cover, number of stolons/hill, yield (ton/ha), dry matter content and    sugar content of the tubers. Results revealed that; days to emergence and number of stems were unaffected by either of the treatments applied. Increasing urea or combination of urea and chicken manure increased significantly crop cover, number of stolons, yield and sugar content of the tubers but did not affect dry matter content. The highest tuber yield was obtained by 180kgN + 20m3 chicken manure /ha in both seasons.  Foliar fertilizer had no significant effect on either of the parameters tested. The significance of interactions observed in this study implies further investigations.
