Water productivity and crop yield in five chickpea varieties – how important is...
Silva, LL; Duarte, I; Simões, N; Lourenço, E; Chaves, MMChickpea (Cicer arietinum L.) is one of the most important pulse crops in the world as a source of protein for human consumption. In Mediterranean regions, chickpea is traditionally grown as a rainfed crop, thus highly dependent on rainfall. In this situation, supplemental irrigation may be applied. The objective of our study was to evaluate the improvement in crop yield and water productivity with supplemental...
Evaluating chickpea genotypes for abiotic stress tolerance
Duarte, I; Silva, LL; Simões, N; Imtiaz, M; Lourenço, E; Chaves, MMBeing a leguminous crop chickpea (Cicer arietinum L.) is important for the establishment of sustainable and economically viable farming systems. Chickpea is grown and consumed across five continents, making this crop more important in international markets than other food legumes. Adaptation trials of 15 accessions of chickpea, 13 from the ICARDA collection and 2 from the Portuguese national catalogue, took pla...
Leaf temperature and photosynthetic performance in chickpea
Pinheiro, C; Simões, N; Costa, M; Toureiro, A; Ribeiro, IC; Lourenço, ME; Silva, LL; Duarte, I; Chaves, MMThe responses of photosynthetic rate and leaf conductance to leaf temperature were evaluated in two contrasting chickpea genotypes (Elixir and FLIP03-46C) grown under field conditions (Elvas, Portugal). Photosynthetic performance was assayed with leaf temperatures ranging from 24ºC to 40º C under controlled VPD. Technical constraints and physiological implications are discussed.
