Several potential new pulses recently identified from an adaptation screening study have entered into the first phase of determining best management practices for production. The study objective was to determine seeding date influence on performance of two cool- and two warm-season new pulses in North Dakota. The experimental design was a RCBD, with four replicates, in a split plot arrangement with three seeding dates as the main plot and pulse crops as the subplot. Seeding dates were targeted for early/mid and mid/late May and early June at Carrington and Prosper. Faba bean and lupin were the cool season, and adzuki and otebo bean the warm season pulses. Field pea and pinto bean were the cool and warm season check pulses, respectively. Traits evaluated were flowering, plant height, seed yield, and seed weight. Seeding date did not influence seed yield for adzuki, faba, pinto, and otebo bean at Prosper, but yield was reduced at the late seeding date for field pea and lupin. Seed yield was reduced for all pulses at the late seeding date at Carrington. Mean pulse seed yield averaged across seeding dates ranged from 558- (lupin) to 3925-kg/ha (pinto bean), and 649- (lupin) to 1405-kg/ha (field pea), at Prosper and Carrington, respectively. Highest pulse yield was achieved from early seeding at Carrington and for early seeding field pea and lupin at Prosper. The study is being repeated in the 2013 growing season at both locations to substantiate seeding date influence on yield response.
