Field experiments were conducted at the National Root Crops Research Institute sub-station, Otobi, in 2006 and 2007 to assess the suitability of improved sweet potato varieties for intercropping with pigeonpea and also to determine the planting pattern and the productivity of the intercropping system. Intercropping decreased total fresh root and saleable root yields of sweet potato when mixed or row-intercropped with pigeonpea. All intercropping combinations of sweet potato varieties and pigeonpea had land equivalent ratio above 1.0, except intercropping with WA Gabolige, signifying high intercrop advantages. TIS 87/0087 produced the highest total fresh root and saleable root yields in both cropping systems, irrespective of the planting pattern used. TIS 2532.O.P.1.13 and TIS 86/00356 sweet potato varieties had comparable yields with TIS 87/0087 in both cropping systems. Pigeonpea was the more competitive component of the intercrop. Farmers showed willingness to adopt the sweet potato + pigeonpea intercropping. Keywords: Intercropping, sweet potato, pigeonpea, Guinea Savanna, Nigeria.

Fifty broiler farms of district Peshawar suspected for infectious bursal disease (IBD) were studied during the period of 25 th September to 20 th October 2007. On the basis of history and detailed postmortem pathological lesions, the prevalence of IBD in district Peshawar was 7.75% and was highest in town 3 of Peshawar district (8.085%). The mortality and morbidity rates were found to be 6.38% and 1.35%, respectively. In district Peshawar the highest mortality rate was recorded in town 1 of district Peshawar with 7.037% and morbidity was highest in town 2 with 1.847%. The major macroscopic lesions observed in this study were hemorrhages on thigh and breast muscles, kidneys were found swollen and principal lesions were in the bursa of fabricious which appeared inflamed, edematous, hyperemic and finally hemorrhagic and atrophied. Four weeks old broilers were highly susceptible to IBD (38%) followed by 3 rd week (28%) and 5 th week (28%) and no clinical case was found positive for IBD in first two weeks of age.

The morphological features of so named “winding layer” in the secondary cell wall of normal and abnormal thin hairs for cotton varieties G. hisutum L., G. barbadense, G. herbaseum L. were studied. Last one is known as defective “thin filament”. The nature and features of normal and thin hairs swelled in cuproammonium solution (Schweitzer’s reagent) is described. The comparative analysis of “winding layer” of two kinds of cotton hairs is performed and it is shown that linear density helixes of winding layer along hair 3-5 times as much than for normal cotton hairs. It is shown that against of normal hairs in thin hairs the cellulose micro fibrils are oriented not under 8-30o (as usual take place for normal cotton hairs) along growth axis. Based on the features of coiled layer of thin cotton hairs the example of pathological defective thin filament is discussed.
