  • Effects of nitrogen source and effective micro-organisms on vegetative growth of shrubs of selected grapefruit (Citrus paradisi Macf) cultivars

ABSTRACT

   Grapefruit (Citrus Paradisi Macf.) is one of the most important citrus fruits in the Sudan. It can be successfully grown throughout the country where there are suitable soils and sufficient water to sustain tree growth. The objectives of this study were to find out the effects of different nitrogen sources, effective microorganisms (EM) and their combinations on the vegetative growth of shrubs of selected grapefruit cultivars. A field experiment was carried out at Umbarona, Wad Medani, Gezira State, Sudan, latitude 14.38 N, longitude 33.48 E and altitude 409 masl, in June 2012. Treatments consisted of three grapefruit cultivars: Marsh Seedless, Red Blush and Shamber. Fertilizer treatments were urea (100%), chicken manure (100%), urea with chicken manure (50% each), urea with EM, chicken manure with EM, urea (50%)+ chicken manure (50%)+ EM and unfertilized control. All fertilizer treatments were applied at the rate of 43 kg N/ha. Treatments were arranged in a split- plot design with two replicates. Grapefruit cultivars were allotted to the main plots and fertilizer treatments to the sub-plots. Data were collected on plant height (cm), stem diameter (cm), number of new branches, length of new branches (cm) and diameter of new branches (cm). Results showed that Marsh Seedless cultivar had the most vigorous vegetative growth compared to the other two cultivars. The results showed that the combination of urea, chicken manure and EM significantly gave the highest vegetative growth values, followed by chicken manure with EM, urea with chicken manure, urea with EM, urea alone, chicken manure alone and the least values of growth parameters were recorded for the unfertilized control. It is recommended to grow Marsh Seedless grapefruit cultivar and fertilize it with a combination of urea, chicken manure and EM.

  • Effects of filtermud on growth and yield of three banana cultivars grown in KenanaSugar Scheme area, central Sudan

ABSTRACT

     Banana is an important fruit crop in the Sudan and its production is mainly confined to the alluvial deposits ofrivers. Organic matter is known to improve soil physical and chemical characteristics and provide plant mineral nutrients. Therefore, the objective of this research was to evaluate the effects of filtermud levels on vegetative growth, yield components and total yield of the mother, first, second and third ratoon crops of three banana cultivars. Field experiments were conducted during December 2012 to November 2014 at KenanaSugar Scheme area. Banana cultivars were the introduced banana clones Williams Hybrid and Grand Nain and the local cultivar Dwarf Cavendish. Levels of filtermudwere 15% and 30% by volume. Treatments were arranged in a randomized complete block design with four replicates. Three months after planting, two plants from each plot were randomly selected, tagged and used for growth and yield measurements.Results showed significant differences among cultivars in vegetative growth, yield components and total yield. The introduced banana clones Williams Hybrid and Grand Nainhad the most vigorous vegetative growth and the highest yield components and total yield compared to that of the local cultivar Dwarf Cavendish.However, Dwarf Cavendish was earlier than the introduced clones. Application of filtermudat both rates resulted in a significant increase in all vegetative growth parameters and in the earliness of banana crop. Filtermud also produced a significant increase in all yield components and total yield compared to the untreated control.It is recommended to grow the introduced cultivars Williams Hybrid and Grand Nain and apply filtermud at the rate of 15% by volume in heavy clay soils.

  • Use of ICTs in Agricultural Higher Education: A case study of the Faculty of Agricultural Sciences, University of Gezira ,Sudan

Traditional forms of higher education systems are no longer exists in many universities and higher institutes in the majority of the developed countries. The use of information and communication technologies (ICTs) in agricultural higher education will lead to improve class room teaching learning process. The purpose of study was to investigate the use of ICTs in agricultural education in the Faculty of Agricultural Sciences, University of Gezira ,Sudan. Field survey was used to collect data from 90 teachers. The collected data were statistically analyzed and interpreted using percentage and frequency distribution and chi-square test. The results showed that the majority of teachers used the ICTs  irregularly because of the lack of them in the majority of the class rooms, therefore they used instead of them the traditional boards such as blackboard and greenboard .It can be concluded that the Faculty of Agricultural Sciences, University of Gezira ,Sudan is still using the conventional systems of higher education as in public universities in developing world. Thus, the faculty members should be motivated, empowered and supported  in order to use the available  ICTs in their teaching activities, the constraints which are facing  the use of ICTs in the  teaching and learning process in the faculty  should be solved and integrating the use of ICTs into the faculty`s strategies and  policy planning.

  • Capacity Building OfAgricultural Extension Staff For Sustainable And Effective Extension Services In Gezira State, Sudan.

This paper investigates the capacity
building (frequency and areas of training )  of the
extension staff ,Gezira State, Sudan in order to
reveal the training needs of them which in turn will
improve the agricultural extension services
delivered to meet the needs of the target groups
they serve. The study was based on primary
(qualitative) data. Thedata were gathered by
administering a questionnaire among all
agriculture staff in the State Descriptive statistics
were employed to analyze and interpret the
collected data using percentage and frequency
distribution. The results showed insufficient
number of training sessions offered to extension
staff in the State. The study established that
according to government employment policy
considerable number of extension staff lack process
skills or human how skills. Therefore the number of
training sessions on process skills or human how
skills should be increased in coordination and
collaboration with agricultural institutions in the
State and the government employment policy
should be directed to give priority to graduated
agricultural cadre specialized in agricultural
extension more than other agricultural disciplines.

  • Role of Private Agricultural Extension Sector in Gezira State, Sudan

Abstract
The aim of this study was to assess the role of private agricultural extension sector in Gezira State ,Sudan. Field
survey was used to collect data from 100 small scale farmers in 2014/2015 growing season using full count
methods. The collected data were statistically analyzed and interpreted using percentage, frequency distribution
and chi-square test. The majority of the results showed significant association between all kind of  extension
services provided by private agricultural extension sector and increase in farmer`s production.
It can be concluded that private agricultural extension sector in Gezira State can play more effective role if it
can be supported by enough well trained extension officers . Thus, The private agricultural extension sector in
Gezira State should be supported by all concerned input companies, local NGOS , individuals and other
agribusiness enterprises and the number of extension field staff should be increases and well trained.
