Effects of irrigation and sowing date on phenology and yield of pinto beans(Phaseolus vulgarisL.) in Canterbury, New Zealand

Abstract

The phenology, yield, and yield components of pinto beans (Phaseolus vulgaris L.) were examined in the 1994/95 and 1995/96 growing seasons in Canterbury, New Zealand. In the first season, irrigation treatments (nil and full) combined with two sowing dates (27 October and 24 November) were studied. In 1995/96, pinto beans were sown on four dates (1, 15, 29 November and 13 December) with or without irrigation. Temperature was about average during the two seasons, but they were drier (50 and 60% of the long-term mean total rainfall, respectively) than usual. There was a highly significant positive relationship (r 2 = 0.98; P < 0.0001) between the rate of development from emergence to flowering (E-F) and mean temperature, but no relationship with photoperiod. All the development stages depended on accumulated thermal time above a base temperature of 7°C. The mean accumulated thermal times for E-F, flowering to podding, podding to physiological maturity, and sowing to harvest were 306, 79, 392, and 974°C days, respectively. Seed yield was up to 378 g/m 2 with irrigation. Fully irrigated crops (averaged over both seasons) yielded 50-70% higher than the unirrigated crops. The mid-late November-sown crops that were irrigated yielded 362 g/m 2 , 15% greater than the irrigated late October-early November and December-sown crops. Seed yield differences among treatments were highly influenced by the number of H98050

Phenology and growth response to irrigation and sowing date of Kabuli chickpea (Cicer arietinum L.) in a cool-temperate subhumid climate

“…Summerfield & These results provide valuable new information for modelling chickpea growth and development in cooltemperate subhumid climates. Simulation models of lentil (McKenzie et al 1994) and pinto bean (Phaseolus vulgaris L., Dapaah et al 1999) growth and development have shown various responses to temperature and photoperiod. The lack of response to photoperiod shown in the present work with these chickpea cultivars indicates that simulation modellers will need to use appropriate equations when modelling all stages, but e-f in particular.…”

Agronomic Practices to Increase the Yield and Quality of Common Bean (Phaseolus vulgaris L.): A Systematic Review

“…Additionally, limited water availability (i.e., soil moisture levels) due to high levels of evaporation also negatively impacts yield components [10], fresh pod [7,9] or grain yields [8,99]. The detrimental effects of prolonged water deficit stress were also recorded in the studies of Dapaah et al [100,101] and Love et al [102], where common bean plants were exposed to no irrigation during the whole cultivation period. Conversely, excess application of water, i.e., to levels above the plant requirement, also limits yield [95] and introduces favourable conditions for disease proliferation, such as that of white mould [103].…”

Yield Response to Pea (Pisum sativum L.) Genotype, Population and Sowing Date

“…Plots with 50 plants m -2 had the highest mean number of pods plant -1 (13.42) and 400 plants m -2 , the least (3.37), a drop of 75%. Dapaah et al, [24] found that a low plant population of pinto beans (Phaseolus vulgaris) gave more pods plant -1 in a November sowing in Canterbury. The reduction in pods plant -1 at high density was due to increased interplant competition.…”
