Organic fertilization

On-farm experiments were conducted in 2017 and 2018 to compare the effect of compost application with regular fertilization practices on soil parameters and date palm nutrition and yield. Treatments included no fertilization, mineral fertilization (2kg urea/tree; = farmers practice), organic fertilization (100 kg compost /tree) and combined fertilization (100 kg compost +2 kg urea per tree). Each treatment was replicated four times, set up in a randomized block design.
