“…Even though bambara groundnut has been reported to be drought tolerant, water stress was still able to affect yield. These results are similar to other studies in the literature (Babiker, 1989;Berchie et al, 2010;Berchie et al, 2012;Mabhaudhi and Modi, 2013), which all reported reduced seed yield in bambara groundnut landraces in response to limited water availability under field conditions. In this study, reduced seed yield, through reduced pod mass and number, may be related to a shorter flowering duration, which limited pod number, while low pod mass may be linked to earlier senescence which affected pod filling.…”

Bambara groundnut is a protein-rich legume, with food-security potential. Effects of irrigation levels and seed coat colour on growth, development, yield and water-use efficiency of local bambara groundnut landrace selections were evaluated under a rain shelter. Emergence was slow, although variation was indicated between landraces. Limited water availability was shown to lower stomatal conductance, although chlorophyll content index was shown to be unaffected. Additionally, growth indices of plant height, leaf number and leaf area index were shown to be lower in response to decreasing water availability. Furthermore, landraces generally flowered and matured earlier while also demonstrating higher water-use efficiency at lower water availability. Seed yield was lower under limited water availability resulting from lower pod mass and pod number. Drought tolerance in bambara groundnut landraces was achieved by reduced canopy size, early flowering and maturity, and maintaining high water use efficiency under stress. 'Brown' and 'Red' landraces responded to water stress better than the 'Light-brown' landrace, suggesting an effect of seed colour on possible drought tolerance.

“…This confirms the crop's resilience as a drought tolerant crop and justifies every research effort to improve and promote it as a food security crop especially for the dry areas. Berchie et al (2010b) observed that farmers and consumers have a preference for white and cream coloured bambara groundnut landraces. Burkina was identified as having a cream seed colour, which Berchie et al 255 gives the landrace an additional advantage in terms of consumer acceptability.…”

The need to obtain crop varieties that are tolerant to heat and drought cannot be overemphasised especially with the threat of climate change to agricultural productivity in sub-Saharan Africa. Bambara groundnut has been identified as a drought tolerant crop; however, variations exist among landraces with respect to drought tolerance. An experiment was therefore conducted to evaluate the performance of five bambara groundnut landraces: Black eye, Burkina, NAV 4, NAV Red and Tom, to drought and heat stress, at the Irrigation Company of Upper East Region (ICOUR) at Tono-Navrongo in the Upper East Region of Ghana. The experiment was arranged in a Randomized Complete Block Design with three replicates. The heat trial was irrigated once weekly to field capacity until crop maturity. The drought trial was irrigated once weekly until 30 DAS, after which irrigation ceased. Burkina, a landrace from Burkina Faso produced the highest pod yield of 1.2 t/ha under the heat treatment. Tom did not produce any pod yield. Under drought, Burkina exhibited the greatest root dry weight and leaf area at 120 DAS, and had the longest leaf area duration (LAD). Burkina exhibited bunch canopy architecture, while NAV 4, NAV Red, and Black eye had an intermediate canopy type and Tom a spreading type. Burkina proved the most drought and heat tolerant among the five landraces evaluated. Though a drought tolerant crop, temperatures beyond 38°C and low relative humidity can negatively affect pod yield of bambara groundnut even when irrigation is provided. It is important to test the performance of a crop under a new environment before money is invested into its production in that environment.

“…The desirable agronomic traits of Bambara groundnut such as yield potential (Berchie et al 2010;BAMFOOD 2012), nutritional composition (Brough and Azam-Ali 1992;Brough et al 1993) drought tolerance and adaptations to marginal soils (Collinson et al 1996;Mwale et al 2007a, b), N-fixation and soil fertility improvement (Kishinevsky et al 1996;Dakora 1998;Herridge and Rose 2000;Herridge et al 2008;Mohale et al 2013) have been documented. The crop largely exists as landraces with few varieties developed through controlled breeding (Massawe et al 2002;Basu et al 2007b;Massawe et al 2007).…”
