Improving Watermelon Growers Efficiency By Grafting Under A Water Scarcity Context
Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2018, Vol 11, Issue 11
Abstract
Grafting has many agronomic advantages. However, there are concerns regarding the higher costs associated with the use of grafted plants in Tunisia. Limited information is available as to whether grafting can be used economically in open field production or not? The objective of this study was to determine the effects of the watermelon grafting on farms’ productivity and water resource use efficiency. Using Data Envelopment Analysis (DEA), this paper evaluates the performance of a sample of watermelon growers. A comparative analysis of technical efficiency was conducted for grafted plants vs non grafted plants to assess the effect of grafting by using a Tobit model. Results indicated that watermelon growers have a poor productivity (53% on average). However, farms growing grafted watermelon are largely more efficient than those adopting nongrafted plants. The technical efficiency is about 63% in grafted mode while it is about 30% in the non grafted one. Results indicated also, that the use of grafted plants may largely save irrigation water because grafting enhances root water uptake. Efficient farms using grafted plants may save 1250m3 /ha. The results suggest that using grafted watermelon plants may enhance technical efficiency by 20% in watermelon farming. It can be concluded that grafting in watermelon plants positively affects farms’ economic performance and Water use efficiency.
