Leading that research is Muhammad Shahid, …
Irrigation Management for Improved Citrus Production
By Davie M. Kadyampakeni and Alisheikh A. Atta The conventional four Rs for nutrient management are right source, right place, right rate and right time. This approach allows growers to synchronize nutrient supply with crop demand, enhance tree health and fruit yield, and abate economic costs and environmental losses. In contemporary farming systems in Florida citrus production, considering a fifth R …
PIECES OF THE PAST — Field Crates: From Mill to Memory
By Brenda Eubanks Burnette The humble field crate has its roots in the practical demands of grove labor, long before citrus became a branded commodity. Often confused with the crate developed in 1875 by E.B. Bean that was used to ship citrus, and which featured colorful citrus crate labels, the field crate’s origin is less about marketing and more about …

Video Shows Citrus Planting Method Has Many Benefits
Texas A&M University citrus scientists who developed a successful planting method to combat diaprepes root weevil found that the method also offers numerous other benefits. In 2013, researchers Mamoudou Setamou and Olufemi Alabi were looking for an effective non-chemical method to physically block the circular foliage-to-underground lifecycle of diaprepes. The pest was attacking citrus roots and killing trees. Their solution …
