“…Our result are supported by the recent finding in tomato crop where water logging reduces the overall plant morphological growth, chlorophyll, increase the amount of ROS production leading to oxidative damage and reduces the fruit yield and quality thereby limiting its commercial production (Rasheed et al, 2017). Limited reports are available in growth stage specific response of onion crop to drought stress (Pelter et al, 2004) however, our finding clearly showed the growth stage specific response of onion crop to flooding stress.…”

“…This could have had a negative effluence on canopy development (primary food producer through photosynthesis) and hence limited resources for the sinks (bulbs) which forms the harvestable yield. Pelter et al, 2004 also found out that if moisture is limited it reduces total yield. Soil moisture and weeds competition could be attributed to the significant different in yield between mulched and non-mulched plots.…”

Onion is an important horticultural vegetable in the urban Zimbabwe market. In Zimbabwe there is a need to improve the yield of onions on garden size areas utilizing locally available materials thereby avoiding purchased inputs which are often unavailable or inaccessible due to no supply or prohibitive price The present studies investigate the effect of trash grass and sawdust mulches in combination with organic and inorganic fertilizers on onion growth and yield. When the two mulching materials were compared, trash grass mulch favored the growth of onions more than sawdust mulch. Mulching improved soil water retention capacity, improved soil structure and suppressed weeds. These features played a significant role in the performance and ultimately the yield of onions. Similarly, total plant weight, aerial leaf weight, bulb weight and yields plot were also higher for samples taken from plots with trash grass mulch than those mulched with sawdust. This work also sought to evaluate mulching materials and fertilizer types on the various components of the onion plant at different stages of development and hence their contribution to the final yield. Trash grass in combination with organic and inorganic fertilizer the final yield improved by 160% and 310% respectively. As for sawdust, final yield improved by 103% and 275% for combinations with organic and inorganic fertilizer respectively. The effect of fertilizer types alone on the growth and yield of onions was less dramatic than that of mulch.

“…However from the crop production point of view any stress adaptive strategy must be associated with superior yield under a given stressful condition. Previous findings reported that water scarcity affects the onion bulb development drastically ultimately affecting its yield potential and quality (Pelter et al, 2004). But the limited information is available on the exact physiological and biochemical mechanism that get altered in response to drought stress in onion crop.…”
