  • The role of Rural Women Schools (RWSs) on increasing income, improving nutrition and food security of rural families, Gezira State, Sudan

The objective of this study was to determine the role of Rural Women Schools (RWSs) on increasing income and improving nutrition and food security of rural families, Gezira State. Field surveys were used to collect data from two rural women schools in the State in the year 2013 and 2014 growing season. 25 RWS participants were selected from each school. Equal number of non-RWS participants (50) were used for comparison, by using the simple random sampling technique. The collected data were statistically analyzed and interpreted using percentage, frequency distribution and chi-square test. The results showed significant association between number of seasons of participation in RWS and adoption of recommended package components for rural women by RWS participants. It can be concluded that the RWS non-formal education approach is very efficient in the transfer of recommended package components for rural women through their participation in various activities of RWS. Thus, RWS approach should become national policy, share authority of extension organizations in control and execution of RWS activities with farmer and women unions for more effective participations of rural women in all activities of the schools and the current curriculum of RWS should be developed.

  • Use of ICTs in Agricultural Extension Services, Gezira State, Sudan

This study attempts to investigate the use of ICT in agricultural extension services, Gezira State, Sudan. Field survey was used to collect data from 100 extension officers in the Gezira State in 2014/2015 growing season using the full count method. The collected data were statistically analyzed and interpreted using percentage, frequency distribution and chi-square test. The results showed that there are many constraints facing the use of ICTs in agricultural extension services in the State. It can be concluded that the majority of agricultural extension services of Gezira State, Sudan are still depending on the use of traditional ICTS in it`s services given to beneficiaries. Thus, The authors recommend that more efforts should be exerted to train extension officers and beneficiaries on the use of modern ICTs and the constraints which are facing the use of ICTs in the agricultural extension services in the State should be solved by all concerned partners.

  • Assessment of genotype x environment interaction and stability of sesame (Sesamum indicum L.) seed yield under rainfed and supplementary irrigation in central Sudan

Sesame knowledge of genotype x environment interaction (GEI) is advantageous in order to have a cultivar that gives consistently high yield in a broad range of environments and to increase the efficiency of breeding programs and selection of the best genotypes. Fifteen genotypes of sesame (Sesamum  indicum L.) were evaluated during 2011 and 2012 rainy seasons, at Wad Medani, Rahad (under supplementary irrigation) and Gedarif (under rainfed), to assess genotype x environment interaction and stability of seed yield. A randomized complete block design with four replicates was used in each location. The analysis of variance procedure revealed highly significant differences among the 15 sesame genotypes for seed yield over the eight environments. The mean squares of environment, genotype and genotype x environment interaction were highly significant for seed yield. Both statistical stability models, i. e. Eberhart and Russell (1966) as well as the Additive Main Effect and Multiplicative Interaction (AMMI) analysis, indicated that genotypes Elgezouli, Promo, Um Shagra and Kenana-2 were the most high yielding and stable genotypes and can be recommended for both rainfed and irrigated areas of central Sudan.

  • Combining ability analysis for seed yield and its components in sesame

Sesame (Sesamum indicum L.) experiments, were carried out in central Sudan during the rainy season of 2009 at two locations (Abu Naama and Sinnar). The hybridization plan consisted of seven male and seven female parents giving 49 crosses following line x tester arrangement. Treatments were arranged in a randomized complete block design with three replicates. The crosses and their parents were sown on the 7th of July for all the experiments at both locations. The traits measured were days to 50% flowering, days to maturity, plant height, number of capsules per plant, number of seeds per capsule, capsule length, 1000-seed weight and seed yield. Analysis of variance revealed that genetic variability was highly significant for all the characters studied at both locations and across them. Combining ability analysis showed that additive gene effects were important for inheritance of days to 50% flowering, plant height, number of capsules/plant, number of seeds per capsule, capsule length, 1000-seed weight, days to maturity and seed yield, whereas non-additive gene effects were important for number of seeds/capsule, indicating that the inheritance of this trait is due to specific combining ability (SCA). Combining ability analysis showed that parents, L7, L5, T2, T5 and T6 were good combiners for high seed yield as well as for most of the other traits measured in this study. Assessment of SCA effects for seed yield at Abu-Namma revealed that hybrid T4 x L4 had a maximum positive SCA effect and a high per se performance followed by T2 x L2, T5 x L5 and T6 x L3, while at Sinnar T6 x L6 had the highest positive SCA effects followed by T6 xL3, T1 x L5 and T2 x L6. However T6 x L3, T1 x L5, T4 x L2 and T2 x L1 exhibited the highest SCA effects across sites. The present study suggested hybrids T6 x L3, T1 x L5 and T4 x L2 to be tested in multi-location trials for commercial utilization, while, parents L7, L5, T2 and T6 can be used in recurrent selection.

  • Genetic variability and interrelationships of grain yield and its components of irrigated rice in Gezira

Nineteen genotypes of irrigated rice were evaluated at the Gezira Research Station Farm, Wad Medani, Sudan, for two consecutive seasons (2004 and 2005) in a randomized complete block design with three replicates. This study was conducted to estimate the genotypic and phenotypic variability, broad sense heritability and traits correlation with grain yield. The highest genotypic coefficient of variation and genetic advance were recorded for plant height and number of panicles/m2, and the lowest for number of tillers/plant, days to 50% flowering, days to 50% maturity and panicle length, in both seasons. High heritability estimates (>80%) were recorded for plant height, days to 50% flowering, days to 50% maturity and 1000-grain weight. The highest estimate of heritability combined with the highest genetic advance as percentage of the mean was shown by plant height and 1000-grain weight, in both seasons. The high yielding genotypes were WITA5 (TOX 3255-82-1-3-2), IRI 3240-108-2-2-3(SAHEL.108)(FKR44) and TOX 3081-36-2-2-3-1. Their grain yields were 4.9, 4.9 and 4.6 t/ha, respectively. Grain yield/ha was significantly and negatively correlated with the percentage of unfilled grains/panicle, plant height and days to 50% flowering. How-ever, it was significantly and positively correlated with number of tillers/ plant, number of panicles/m2,number of filled grains/panicle and 1000-grain weight, in both seasons. Path coefficient analysis indicated that number of filled grains/panicle, 1000-grain weight and number of panicles / m2 were the most directly related traits to grain yield/ha.
