“…Agronomic practices that promoted water conservation and soil fertility (e.g., mulching) had been shown to produce higher lentil yield under rainfed condition (Singh et al, 2009). Similar practice might also improve the yield of common bean as nitrogen (N2) fixation of the species was particularly sensitive to high soil temperature (Piha and Munns, 1987) and water stress (Ramos et al, 2003). Breeding for drought-tolerant lentil, common bean, and pigeon pea, however, might require combination with their wild species, considering that the cultivated species exhibited narrow level of genetic diversity due to geographical isolation during domestication events (Ferguson et al, 1998;Kwak and Gepts, 2009;Yang et al, 2006).…”

As a result of climate change, drought is predicted to pose greater pressure on food production system than in the past. At the same time, crop yield co-varies with both environmental (e.g., water, temperature, aridity) and agronomic variables (i.e., crop species, soil texture, phenological phase).To improve our quantitative understanding on the effect of these co-varying factors on agricultural productivity, we synthesized previous meta-analysis studies summarizing the results of numerous independent field experiments on drought and its effect on the production of cereal, legume, root and/or tuber (root/tuber) crops. We also included new crops species that were not covered in previous meta-analyses and the effects of heat stress. Our results indicated that cereals tended to be more drought resistant than legumes and root/tubers. Most crops were more sensitive to drought during their reproductive (i.e., grains filling, tuber initiation) than during their vegetative phase, except for wheat, which was also sensitive during vegetative phase. Recovery from drought impact at reproductive phase was either: (i) unfeasible for crops experiencing damage to their reproductive organs (e.g., maize, rice) or (ii) limited for root/tuber crops, provided that water was abundant during the subsequent root/tuber bulking period. Across soil texture, the variability of yield reduction for cereals was also lower in comparison to legume or root/tuber crops, probably due to the extensive and deep rooting system of cereal crops. As crop species, plant phenology, and soil texture were important co-varying factors in determining drought-induced crop yield reduction, no single approach would be sufficient to improve crop performance during drought. Consequently, a combination of approaches, particularly site-specific management practices that consider soil conditions (i.e., intercropping, mulching, and crop rotation) and selection of crop varieties adjusted to the local climate should be adopted in order to improve the sustainability of agricultural production in a changing climate.3

Rooting, nodulation and growth ability of cowpea growing under limited water supply was investigated at the Teaching and Research Farm of the Imo State University, Owerri, Nigeria. The experiment was conducted in plastic buckets arranged in a completely Randomized Design with three replications, and treatments represented as 500ml, 1000ml, and 1500ml of water, respectively. Control treatment was represented by cowpea plants that grown with rain-fed water. The 500ml and 1000ml of water were applied two times a week to the receiving cowpea plants while the 1500ml was applied daily to the receiving cowpea. Data were collected on the number of nodules/plant, root length/plant (cm) measured at 2 and 4 wks after planting (WAP) respectively, number of leaves/plant, number of branches/plant and seed yield (kg/ha) collected data were subjected to analysis of variance at the 5% level of significance. Results showed that cowpea plants that received 500ml of water produced mean nodule of 6.0 which was significantly (p<0.05) from the mean nodule of 13.2 produced by cowpea plant that grew under rain-fed condition. Cowpea plants that received 500 and 1000ml of water produced mean roots length of 9.8cm and 19.5cm at both 2 weeks and 4 weeks after planting, respectively, which were significantly (p<0.05) longer than 5.2cm and 13.4cm mean roots length in the control, at 2 and 4 WAP. Cowpeas that received 500ml of water produced mean plant height of 117cm and number of branches of 1.0 which were significantly different (p<0.05) from the mean plants height of 47cm and number of branches of 4.1 in the control plants. Seed yield was significantly (p<0.05) higher in the control plants than in the plants that received 500 and 1000ml of water, respectively. It was concluded that root characteristics nodulation potential and seed yield of cowpea were affected by the limiting water supply. Optimal water supply for cowpeas growing in pots should therefore be studied for better irrigation management and optimal performance of cowpea.

“…It also maximizes the assimilation and accumulation of the protein amount in the grain. The symbiotic fixation of atmospheric N 2 occurs due the nodule formation, in which it promotes the nitrogen assimilation (Ramos et al 2003), it is presented as an advantage in smaller expense with nitrogen fertilizer.…”

The study aimed at evaluating and comparing changes provoked by the water deficit on water relations and nitrogen fixation in two Vigna unguiculata cultivars, as well as at indicating which cultivar is more tolerant under water deficiency. The experimental design used was entirely randomized in factorial scheme, with 2 cultivars (Pitiuba and Pérola) and 2 water regimes (control and stress). The parameters evaluated were the leaf relative water content, stomatal conductance, transpiration rate, nodule number, nodule dry matter, nitrate reductase enzyme activity, ureide concentration and leghemoglobin in nodule. The stomatal conductance of the Pitiuba and Pérola cultivars under water deficit were 0.20 and 0.01 mmol H 2 O/m 2 /s, respectively. The nitrate reductase activity of the plants under stress was significantly reduced in both cultivars. The leghemoglobin in the Pitiuba and Pérola cultivars under water stress had the concentrations of 58 and 41 g/kg dry matter, respectively. The parameters investigated in this study suggest that the Pitiuba cultivar under water deficit suffers from smaller changes, when compared with Pérola cultivar.
