“…The TPRI site had both higher minimum and maximum temperatures than SARI, with maximum temperatures averaging 36˚C in 2016 and 33˚C in 2017. This was also hotter than the sites tested in Whitbread et al [22](maximum 32˚C), and in Sennhenn et al [23] (maximum 31˚C). A growth chamber experiment by Sennhenn et al [24] testing the effect of temperature on development of lablab found that flowering was delayed at temperatures higher than 28˚C.…”

“…Previous studies also report a wide range in lablab yields with few consistent responses to precipitation. Whitbread et al [22] tested 33 lablab accessions in South Africa and found in one site year at 475 mm of precipitation yields ranged from 1-576 kg ha -1 . Sennhenn et al [23] tested lablab over a moisture gradient and found lablab grain yields as high as 1271 kg ha -1 with 190 mm of rainfall.…”

Climate change is posing severe challenges in Africa, where resilient crops are urgently needed to withstand drought periods and unreliable rainfall. Multipurpose legume species, such as lablab (Lablab purpureus (L.) Sweet), have been under-utilized yet have the potential to overcome climate challenges. While lablab is native to Africa, there are few characterized varieties and it is under-utilized by smallholder farmers due to a lack of information and access to varieties. Knowledge is especially lacking on the performance of this crop by genotype, management, and environment. We conducted a two-year field study at two sites to evaluate 29 lablab cultivars under sole and maize intercrop management, with 14 cultivars selected for in-depth study. Cultivars were evaluated on vegetative biomass and grain yield production, with N fixation assessed for one site year. Biomass and grain production differed across environments and cultivars, with only biomass affected by intercropping. Average grain yield was substantially reduced to only 37 kg ha-1 in environments with maximum temperatures greater than 33˚C, but biomass production yielded comparable amounts across high temperatures and in dry (<500 mm rainfall) environments. Tradeoffs were found between biomass and grain yield across high yielding cultivars, with the top three grain accessions averaging 612 kg ha-1 of grain and 1.97 Mg ha-1 biomass whereas the top three biomass accessions produced 327 kg ha-1 grain and 2.52 Mg ha-1 biomass across all environments. In a comparison of production and N fixation measurements, cultivars were identified which may have high performance in both. Suitability of lablab for grain and biomass production were visualized across Tanzania in a map comparing max temperature thresholds for grain and biomass against average regional livestock populations. This provides a way forward for identifying potential areas for lablab cultivation as a novel means to enhance fodder and pulse production with smallholder farmers.

“…Green manuring with legumes in pre-cultivation has the potential to increase soil fertility and incorporate N in production systems of family farmers (Fageria and Baligar, 2005;Nyambati et al, 2006). Their use for common bean production can prove economical as compared to that of mineral nitrogen (N) fertilizers (Teixeira et al, 2006;Pietsch et al, 2007), while improving soil properties and increasing crop productivity in a sustainable way (Teixeira et al, 2006;Whitbread et al, 2011). There are reports of the use of legumes as green manure for the common bean crop.…”

“…There are reports of the use of legumes as green manure for the common bean crop. However, its effectiveness varies considerably owing to a number of factors, such as chemical, physical, and biological soil properties; the legume species used; local growing conditions; and the residual effect of N fixed by legumes, as well as interactions of these and other factors (Roldán et al, 2007;Whitbread et al, 2011).…”

“…Both species are already cultivated by some family farmers and can be easily grown at Minas Gerais Atlantic Forest Zone. The hyacinth bean grows well in a variety of environmental conditions and is tolerant to low soil fertility (Maass et al, 2010;Whitbread et al, 2011;Guretzki and Papenbrock, 2013). The jack bean has early maturity, is erect, and shows semi-determinate growth, in addition to being adaptable to various climatic conditions, ranging from the adverse arid and semi-arid regions to the hot and humid climate of the regions with tropical forests (Teodoro et al, 2011).…”

The use of legumes in pre-cultivation on the common bean has the possibility of providing atmospheric N to the soil, making it available to this crop, and may cover part of its N demand and increase grain yield. The objective of present study was to evaluate the effect of hyacinth bean and jack bean as green manures on the production of common bean grown in two seasons. Cover crops were evaluated for fixed N 2 , dry matter yield, nitrogen (N) and carbon (C) concentrations, C:N ratio and N accumulation in the shoot. The jack bean accumulated higher biomass and more total N than hyacinth bean and spontaneous vegetation (control). However, both legume species, when used as green manure, resulted in an increase in the N concentration of common bean. Compared to the spontaneous vegetation, hyacinth bean residue increased yield of common bean by 32% and jack bean residue increased the bean yield by 46%. These yields were recorded when common bean was cultivated a few weeks after residues incorporation into the soil and about seven months later, thus showing a flexibility to family farmers for making their decisions on the best cropping season.
