Yield and Water Productivity of Chickpea (<i>Cicer arietinum</i> L.) as Influenced by Different Irrigation Regimes and Varieties under Semi Desert Climatic Conditions of Sudan

Abstract

A field experiment was conducted at Hudeiba Research Station Farm, located at Ed-Damer, Sudan during 2011/2012 and 2012/2013 winter seasons to investigate the effect of different irrigation regimes and varieties on chickpea (Cicer arietinum L.) yield, yield components and water productivity. The treatments include three irrigation regimes; irrigation every 10 days (I 1 = full irrigation), irrigation every 15 days (I 2 = moderate stress) and irrigation every 20 days (I 3 = severe stress) and two varieties (Borgieg and Wad Hamid). The treatments were arranged in factorial randomized complete block design (RCBD) with 3 replications. Irrigation water being applied, grain yield, yield components (number of pods per plant, number of seeds per pod and the 100 seeds weight) and crop water productivity (CWP) and irrigation water productivity (IWP) were recorded. Results showed that the number of pods per plant, number of seeds per pod, 100-seeds weight, grain yield and irrigation water applied were significantly (p ≤ 0.001) affected by irrigation regimes. The highest values of these traits obtained with full irrigation, whereas the lowest values were recorded under severe water stress conditions. Results also indicated that, moderate and severe water stress regimes saved irrigation water by 24% and 32%, respectively compared with full irrigation. This study indicated that treatment I1 which was irrigated every 10-days did * Corresponding author. M. K. Alla Jabow et al.1300 not produce the highest IWP, while treatment I 2 which irrigated every 15-days gave the highest IWP. The lowest IWP occurred at severe water stress regime (I 3 ). It could be concluded that moderate water stress might be adopted. Contrarily, the adoption of severe water stressed that produce high water savings would lead to yield losses that might be economically not acceptable. The late maturing chickpea variety of Borgieg significantly (p ≤ 0.05) out-yielded the early maturing variety Wad Hamid by 11%. Borgieg displayed the highest values of CWP and IWP.

Effects of Water Intervals on Growth and Yield of Three Chickpea Cultivars (Cicer arietinum L.)

“…The highest number of pods per plant was observed in 10 days intervals in Atmore (late flowering) than Wad Hamid and Shendi (early flowering). Similar results were reported by (AllaJabow, et. al., 2015).…”

“…And this perhaps referred to the role of water stress in old leaves, which will lead to shedding and resulting to reduce the total number of leaves. (AllaJabow, et. al., 2015) they found that the effect of water stress coincides with various growth stage such as germination; seedling and shoot length.…”

Effect of Water Regimes and Polyvinyl Alcohol on Faba Bean Yield, Chemical Composition and Water Use Efficiency

“…Such trend is mainly due to the differences in climatic conditions and sowing date between both seasons of study. Similar conclusion was reached by Mohammad (2014), Moursi et al (2014) and Jabow et al (2015). Appropriate frequency of irrigation can be determined from the available soil moisture retaining capacity and the rate of faba bean evapotranspiration taking into consideration that it better replenish the soil moisture when about 50% of the total available soil water is exhausted (Allen et al,1998) With respect to, the effect of applied different concentrations (0.2, 0.1, 0.05 and zero %) of polyvinyl alcohol as soil conditioner on total mean actual faba bean evapotranspiration (ETa) results illustrated in Table 3& Table 4 and Figure1.…”

Impact of Irrigation Methods, Irrigation Scheduling and Mulching on Seed Yield and Water Productivity of Chickpea (Cicer arietinum)

“…The farmers practice (CB7) recorded the lowest WP of 0.30 kg/ m 3 . Interestingly Jabow et al (2015) observed that in desert conditions of Sudan, chickpea crop exhibited higher water productivity when the interval of irrigation was 15 days as compared to 10 days.…”
