“…The variation among wheat genotypes in number of spikes/m 2 could be attributing to genetic variation (Table 2). These results are in harmony with those reported by Salem, (2005) found significant differences among eight bread wheat varieties in number of spikes/m 2 , Khalil et al, (2006), Gab Alla (2007, Abd El-Rahman (2008) and Abdel-Nour and Fatheh (2011) confirmed similar obtained results. Data presented in Table (4) indicated that, the genotype; Gemmeiza 11 recorded the highest values for number of grains/spike, biological yield, and straw yield.…”

This investigation was performed during the two successive growing seasons 2018/19 and 2019/20 to study the effect of three irrigations and three nitrogen levels on yield and yield components of four common wheat cultivars. The highest number of spikes/m 2 , grains/spike, straw yield, biological yield, grains/spike and 1000-grain weight recorded by increasing number of irrigations from one to four irrigations. Grain yield/fad were significant only in the second growing season. Plants that received two or four irrigations produced the highest significant values of grain yield/fad. Concerning fertilization, the highest significant values of yield and yield components were obtained from fertilized wheat plants with 100 kg N/fad in both seasons, while the lowest one was obtained from 50 kg N/fad in both seasons. Banei Sweif 6 cultivar recorded the highest number of spikes/m 2 in both seasons, while Gemmeiza 11 recorded the highest number of grains/spike, straw yield and biological yield. The highest means of 1000-grain weight, and grain yields were detected in Banei Sweif 1 in both seasons. The interactions of irrigations regimes x N fertilization levels were significant for biological yield, straw yield in the second season. The interactions of irrigations regimes x genotypes were significant for biological yield, straw yield in both season and for harvest index in one season. On the other hand, interaction among the three study factors did not reach the level of significance for all studied traits. We conclude from the results that irrigation four times and twice gave the highest yield values compared to irrigation once, and it is recommended to add nitrogen fertilizer at a rate of 100 kg nitrogen per feddan to maximize the productivity of the wheat crop, under the environmental conditions of this experiment.

“…The high % of "No" response indicated that the farmers hardly considered irrigation schedule in farming systems and agricultural practices. The farmers might not see irrigation scheduling practice as a primary tool to improve water-consuming efficiency, enrich availability of water resources, enhance soil quality and boost crop yields (Khalil et al 2006). The respondents might hardly see the necessity for crop water productivity linked to irrigation scheduling, which FAO (2003) emphasized as a useful indicator.…”

The threats of climate change on agricultural systems, water availability and crop performance put pressure on food security and zero hunger. The effects call for multifaceted mitigation and necessitate this research to investigate water management (W.M.) and crop varieties (CRV) adaptation being used by the rain-fed farmers that have the records of yearly high agricultural produce. The research distributed 1600 copies of pretested questionnaire across four (Benue, Edo, Niger and Ondo) states in Nigeria through the national Agricultural Development Programmes offices. The retrieved copies were coded in Excel spreadsheet, descriptively analysed in SPSS v23 and subjected to multiple regression analysis. The results indicated that three W.M. (riverside cultivation, irrigation practising and mulching) entered the Benue model but each for Ondo, Edo and Niger, respectively. All the CRV (SDT: selecting different technology, HYV: high yielding varieties, WRV: water-resistant varieties, DRV: drought-resistant varieties except DiRV: disease-resistant varieties) entered the Benue model, but DRV for Edo, WRV and DRV for Niger while DiRV for Ondo. General data of each state was significant (p < 0.05). Benin and Niger States had the highest variance (12.5 % W.M. and 21.7 % CRV). Durbin-Watson value < 2 indicated positive autocorrelation. Mulching worked best for farmers across the states while WRV and DRV were not in Ondo and Edo. Choice of W.M. and CRV differed across the study states and the research would suggest different climate change adaptation for farmers on both water management and crop varieties.
