“…This suggest that the effects of the extract are concentration dependent. This affirms the reports of Folarin et al, (2015), Marley et al, (2004), , and Kolawole et al, (2018) who found the effects of some tree species on vegetables and crops to be concentration dependent with significant difference between treatments.…”

This study examined the allelopathic effect of different concentration of aqueous extracts of Parkia biglobosa stem bark on the germination and growth of weed seeds species. Seeds of Eragorastis tenella, Eragorastis atrovirens, Pannicum pedicellata, Pennisetum sub albidum, Hypharrhenia rufa and Brcichiaria brizantha were tested for plumule germination and radicle growth with three different concentrations of 1%, 5%, 10% plant extract while ordinary water was used as control. Growth parameters including germinated weeds population were measured; the highest germinated weeds population was at the control (8.06±3.97) and the least was obtained from the 10% concentration with the mean of (4.42±2.59). Weeds population decreased as the concentration increased. The highest mean of weeds height was recorded from 1% concentration (11.46±7.08) which is statistically significant while the least mean was recorded from 10% concentration (7.69±6.70) statistically not significant. The family emergence by concentration indicated that, the experiment under control had (4 families) for 1% (2 families), 5% (2 families) and 10% (4 families) emerged. The germination, radicle and plumule length were inhibited when compare with control and the inhibition was statistically not significant at.

“…It is recommended that crops grown under Shea trees are shade tolerant [1]. More so, an increasing number of studies find that Shea tree has inhibitory effects on certain crops [1,10–12]. The magnitude of the inhibition ranges from those that are not statistically significant and do not cause significant differences in yields, to those that are statistically significant leading to significant reduction in yields.…”

“…The influence of planting season and crop productivity under Shea has not been widely reported. Majority of the studies on inhibitory effects of Shea tree are single season studies such as those of Aleem et al, 2014, [11] or bioassays that involve planting the experimental crops in soils incorporated with extracts of mature Shea tree components such as those of Folarin et al, 2015, [12]. It is widely accepted that variations in seasons have significant influence on crop productivity [1].…”

Influence of Shea tree (Vitellaria paradoxa) on maize and soybean production

Vitellaria paradoxa provides many benefits to farmers within the Shea belt. However, increased threats to it necessitate its conservation, and one common approach is the practice of agroforestry. A number of studies have shown that Shea tree has influence on crop production, and yet, some of these studies were done using single season experiments or bioassays using mature Shea tree components. In this study, the seasonal influence of young and mature Shea trees on Maize and Soybean yields was investigated using field experiments in Otuke district of northern Uganda, where, Shea tree parklands are dominant and Maize and Soybean are used for food security and income. Our results show that there are differential responses of maize and soybean yield to rainy seasons and physiological variations of Vitellaria paradoxa with age. We find yield reduction for maize more pronounced than yield reduction for soybeans under different Shea age (Mature and Young) for two rainy seasons. We attribute the variance to the differential maize and soybean responses to Vitellaria paradoxa shading and its differential allelopathic inhibition of these crops. We recommend that Soybeans should be preferred to maize when planting under Shea canopy.

“…A number of scholars and 40 stakeholders agree that there is need to conserve Vitellaria paradoxa due to its economic 41 potential and threats to it (Buyinza & Okullo, 2015). These threats include burning the tree 42 for charcoal, and large scale clearing of the Shea tree to pave way for mechanized agricultural 43 production ( Folarin et al (2015). It is widely accepted that variations in seasons have significant influence on crop productivity (Boffa, 2015).…”

9Vitellaria paradoxa provides many benefits to farmers within the Shea belt. However, 10 increased threats to it necessitate its conservation, and one common approach is the practice 11 of agroforestry. A number of studies have shown that Shea tree has influence on crop 12 production, and yet, some of these studies were done using single season experiments or 13 bioassays using mature Shea tree components. In this study, the seasonal influence of young 14 and mature Shea trees on Maize and Soybean yields was investigated using field experiments 15 in Otuke district of northern Uganda, where, Shea tree parklands are dominant and Maize and 16Soybean are used for food security and income. Our results show that there are differential 17 responses of maize and soybean yield to rainy seasons and physiological differences of 18 Vitellaria paradoxa treatment. We find yield reduction for maize more pronounced than yield 19 reduction for soybeans under different Shea plants (Mature and Young) and for the two rainy 20 seasons. We attribute the difference to the differential maize and soybean responses to 21 Vitellaria paradoxa shading and its differential allelopathic inhibition of these crops. We 22 recommend that Soybeans should be preferred to maize when planting under Shea canopy. 23 24
