    A Note on Some Reproductive Traits in Crossbred Dairy Cows at Elneshasheba Dairy Farm in Wad Medani, Sudan
    (Faculty of Agriculture, University of Khartoum, Shambat, Sudan, 2001) Elimam, M.E. ; Ali, S.M.
    Dairy records were collected from Elneshasheba Dairy Farm at Wad Medani, Sudan, to study the reproductive performance of crossbred dairy cows in the area. Age at first calving was the least for 62.5% exotic blood, and was significantly different from the two groups (50% and 75%) which were not significantly different from each other. The number of services/conception and gestation length were not significantly affected by the percentage of exotic blood or calving number. The percentage of exotic blood and calving number significnalty affected calving intervals. The birth weight of calves was significantly affected by calving number but not by the percentage of exotic blood.

    A Note on Yield of Groundnut, Sesame and Millet Under Alley Cropping with Acacia senegal (L) Willd. in Northern and Southern Kordofan States
    (Faculty of Agriculture, University of Khartoum, Shambat, Sudan, 2001) Hussein, S.G. ; Fadl, K.M.
    A study was conducted in two forest reserves in Northern and Southern Kordofan States to (i) evaluate the effect of Acacia senegal on the growth and yield of groundnut, sesame and millet, (ii) determine the suitability of these crops under alley cropping, and (iii) indicate the feasibility of agroforestry as a farming practice. Yield of the three crops was more with alley cropping than with sole cropping in the two sites, and groundnut proved to be most compatible with Acacia senegal followed by sesame and millet.

    A Note on a Detection Survey of Citrus Tristeza Virus and Indexing Citrus Germplasm Collection in the Gezira, Sudan
    (Faculty of Agriculture, University of Khartoum, Shambat, Sudan, 2001) Mohamed, M.E.
    A survey was carried out on several citrus plantings in the Gezira State and citrus germplasm collection at the Gezira Research Station to detect Citrus Tristeze Virus (CTV). ELISA test gave negative results for all samples used, indicating that CTV, if found in the Sudan, is not spreading. The test also confirmed that the newly introduced budwood is free from CTV.

    An Economic Analysis of Wheat, Broad Bean and PRIVATE Sorghum Production in the Northern State of the Sudan
    (Faculty of Agriculture, University of Khartoum, Shambat, Sudan, 2001) El Fiel, M.A. ; Babiker, B.I. ; Davis, J.
    This study was carried out (i) to identify the main economic constraints on the production of three main field crops (wheat, broad bean and sorghum) in the Northern State of the Sudan; (ii) to examine the efficiency of farmers in allocating resources to these crops; and (iii) to determine the attitude of farmers towards risk and the influence it may have upon their production decision-making process. The results indicated that although resources appeared to be allocated efficiently, there were severe constraints on the supply of certain inputs, and credit to purchase inputs was virtually unavailable. Given such an inelastic supply of some inputs, farmers pre­ferred tto minimize risk rather than maximize profit.

    Groundnut Shared Tenancies and Farmer's AllocativePRIVATE Efficiency in the Rahad Agricultural Scheme
    (Faculty of Agriculture, University of Khartoum, Shambat, Sudan, 2001) Eisa, E.A.H.M ; El Fiel, M.A.
    This study was carried out to assess the implications of groundnut share contracts on farmer's allocative efficiency in the Rahad Agricultural Scheme. One hundred respondents were randomly selected through a field survey during 1995/96 season. A log-log Cobb-Douglas production function was fitted to the data as well as tabular and descriptive statistics. The study revealed that groundnut owner cultivators were efficient in allocating land and capital expenses, whereas those engaged in groundnut share contracts were only efficient in allocating their labour. In addition, not only poor tenants do share their groundnut holdings but also rich ones do so. Moreover, sharecropping was found to reduce farmer's income realized from share holding although the two types of holdings did not differ significantly in groundnut yield.
