A successful expansion and intensification of the links between tourism and horticulture is needed for tourism to contribute to economic diversification. Without inter-sectoral coordination and the cultivation of sustainable links between tourism demand and other sectors in the destination’s economy, tourism will be unable to function as a driver of tourist attraction. Therefore, tourism needs to establish ties with other industries, such as agriculture, to positively contribute to the surrounding area’s economy and improve the quality of life in rural and urban areas. The current study explores the sustainable gardening practices (SGP) in hotels and their impact on predicting tourist revisit intention with the mediating role of tourist attitudes (ATT) toward green hotels and assessing the environmental gardening identity (EGID) as a moderator. Dyadic data were collected from 286 guests and hotel gardeners and was analyzed by PLS-SEM. The results revealed that sustainable gardening practices positively (R2 = 0.581) and significantly (p > 0.05) improve tourist revisit intention through the mediating role of tourist attitudes toward green hotels. At the same time, the empirical results supported the moderation effects of the EGID on the links between SGP and ATT. Several practical and theoretical implications were discussed and elaborated upon.

Al-Hassa oasis is considered as the biggest irrigated one in the World, being well known for its extensive date palm cultivation with an estimate of at least three million trees. The aim of this study is to evaluate the impact of soil fertilization practices on the productivity potential of date palm trees grown under the climatic conditions of Al-Hassa oasis, KSA. The opinions of 258 active farmers were randomly surveyed using specifically designed questioners that were also fortified with personal communications. The size of the samples was designated in accordance to Cocoran equation. The total samples were allocated into two major parts (193 for the old oasis and 65 for the new oasis). Results showed that the farm features (utilized agricultural area (UAA), ownership and labors) are different in both parts of the oasis. Fertilization practices (quantity applied per area or per tree) were diverse causing dissimilar productivity potentials (total or per area or tree). The average production of a tree in the old oasis is 81.4 kg, whilst it is 54.6 kg in the new oasis. Date palm production is significantly affected by total number of trees, applied fertilizer quantity, cultivated area and labor power. The impact of these factors is unlike between the two parts of the oasis. It is then concluded from the study that there are sincere needs for improving the soil fertilization practiced for the date palm trees grown in the Al-Hassa oasis, KSA in order to increase their productivity potential and hence improve the farmers' income.
