dc.description.abstractA field study was initiated in the spring of 1996 to investigate the N and P fertility requirements of chickpea. Experiments with desi- and kabuli-type chickpea were conducted in the Dark Brown Soil zone at Outlook, Moose Jaw, Elbow and Watrous on soils with relatively low levels of available N and/or P. The experiments consisted of 12 treatments which included four levels of "starter N” (46-0-0 at 0, 15, 30, and 45 kg N ha-1) and 3 levels of seed-placed P2O5 (11-54-0 at 0,20, and 40 kg P205 ha-l). Regular monitoring of the plots indicated that although growth stages during active plant growth (i.e., days to flowering, pod formation, etc.) were largely unaffected by fertilizer application, seed maturity was, in some instances, extended as a consequence of fertilizer application. Symbiotic N, fixation was estimated using the difference method with flax (var. McGregor) as the non-fixing reference crop. Data suggest that increasing increments of fertilizer N resulted in concomitant reductions in symbiotic N, fixation by kabuli-type chickpea whereas symbiotic N, fixation by desi-type chickpea was less sensitive to inorganic N. Application of “starter N” and seed-placed P205 did not confer a predictable seed yield advantage to either desi- or kabuli-type chickpea.en_US
