“…In 2006, however, ITH98-46 together with Vuli-1 recorded the highest concentrations of Fe, Zn, Cu, Mn and B in edible leaves, as well as Fe, Cu and Mn in grain (Table 4). These variations in the mineral profile of cowpea leaves and grain between years could be attributed to soil factors, including moisture, available mineral N and quality and quantity of soil bacteria nodulating cowpea [28][29][30]. We have reported elsewhere that cowpea genotypes exhibit nodulation preferences for their microsymbionts even when planted in the same soil [31].…”

Legumes are a good source of calories, protein and mineral nutrients for human nutrition and health. In this study, the edible leaves and grain of 27 field-grown cowpea genotypes were assessed for trace elements and macronutrient density at Manga in the Sudano-Sahelian zone of Ghana in 2005 and 2006, using inductively coupled plasma-mass spectrometry. The genotypes differed markedly in their accumulation of trace elements and major nutrients in edible leaves and grain. Except for P, the concentrations of K, Ca, Mg, S and Na were much higher in edible cowpea leaves than grain in 2005. A similar pattern was observed for Ca, Mg, S, Na in 2006. However, more dramatic variations were found in the micronutrient concentrations between edible cowpea leaves and grain. The levels of the trace elements Fe, Cu, Zn, Mn and B were sometimes 2-to 20-fold greater in leaves than grain of cowpea. Furthermore, there were strong geno-typic differences in mineral density of cowpea leaves and grain. For the major nutrients, for example, IT93K-2045-29 and IT90K-59 accumulated greater concentrations of P, K, Ca, S and Na in both edible leaves and grain in 2006, while ITH98-46, which showed the least macronutrient density, exhibited the highest concentrations of Fe, Zn, Cu, Mn and B in edible leaves, as well as Fe, Cu and Mn in grain. These results have implications for cowpea breeding, as well as for human nutrition and health.

. 2010. Nitrogen dynamics of chickpea: Effects of cultivar choice, N fertilization, Rhizobium inoculation, and cropping systems. Can. J. Plant Sci. 90: 655Á666. Understanding N dynamics in relation to cultural practices may help optimize N management in annual legume crops. This study was conducted at six environsites (location )year combinations) in southern Saskatchewan, 2004Á2006, to quantify N uptake, N 2 fixation, and N balance in chickpea (Cicer arietinum L.) in relation to cultivar choice, cropping systems, rhizobial inoculation, and soil N fertility. The cultivars Amit, CDC Anna, CDC Frontier, and CDC Xena were grown at N fertilizer rates of 0, 28, 56, 84, and 112 kg N ha (1 with no Rhizobium and at 0, 28, and 84 kg N ha (1 combined with Rhizobium inoculation, evaluated in both conventional tilled-fallow and continuously cropped no-till systems. Flax was used as a non-N-fixing reference crop. The cultivar CDC Xena had the lowest yield (1.57 Mg ha(1 ) and seed N uptake (54.4 kg N ha (1 more N into the seed and 5 kg ha(1 more N into the straw than chickpea that was not inoculated. The amount of N fixed as a percentage of total N uptake was 15% for non-inoculated chickpea and 29% for inoculated chickpea, resulting in negative N balance regardless of cropping system. Increasing N fertilizer rates decreased NUE, with the rate of decrease being greater for noninoculated chickpea compared with inoculated chickpea. We conclude that optimum productivity of chickpea can be achieved with application of effective Rhizobium inoculants, and that best N management practices must be adopted in the succeeding crops due to a large negative N balance after a chickpea crop. For personal use only.

“…At 75 DAS the maximum number and dry weight were achieved under irrigation at  = -0.03 MPa at 30 cm soil depth (I 3 ) where the rate of increment were 9.17 and 9.67% over the treatment receiving irrigation at  = -0.05 MPa 30 cm soil depth (I 2 ), respectively. Water restriction drastically affected nodulation of the crop was stated by Kurdali et al (2002). Broad bean treated with 75 kg P 2 O 5 ha -1 (P 4 ) recorded maximum nodule number and dry weight plant -1 which was followed by the treatment comprised of 50 kg P 2 O 5 ha -1 (P 3 ).…”

A field experiment was carried out during rabi seasons of 2009-10 and 2010-11 to study the effect of irrigation and phosphorus levels on growth, yield and nodulation of broad bean. Treatment receiving irrigation at  = -0.03 MPa at 30 cm soil depth (I 3 ) maintained its superiority with 5.11 and 34.97% higher seed yield compared to irrigation at  = -0.05 MPa at 30 cm soil depth (I 2 ) and rainfed (I 1 ), respectively. Treatment receiving 75 kg P 2 O 5 ha -1 (P 4 ) was significantly superior with 9.26 and 28.26% higher seed yield over 50 kg P 2 O 5 ha -1 (P 3 ) and 25 kg P 2 O 5 ha -1 (P 2 ) treatments, respectively. Growth, yield attributing characters and nodulation also followed the trend of seed yield. The treatment combination receiving irrigation at = -0.03 MPa at 30 cm soil depth along with 75 kg P 2 O 5 ha -1 (I 3 P 4 ) proved as best treatment combination.
