Growth-Based Irrigation in Mango

Mango trees are known for their pattern of alternate bearing, in which the yield alternates between being large and small. After a small yield, the trees can take up to 4 years to return to their previous high yield. This causes many commercial difficulties for farmers. SupPlant’s autonomous irrigation systems are proven to lead to a more regulated yield pattern while significantly reducing the amount of water needed.

With SupPlant’s growth-based irrigation (GBI) system in place, mango fields showed higher regularity in yield levels. With autonomous irrigation in place, low yields weren’t as low as usual and returned to normal within a shorter time period. 

 

The trial took place at a mango plantation, in the northern part of Israel with the Shelli Mango variety. The purpose of the trial was to implement SupPlant’s Growth-Based Irrigation (GBI) technology in the commercial plot. 

The trial that started in March 2016, was carried out at plot ’35 GBI’ which was planted in 1983. As a control plot, ‘Plot 31’ was chosen with the planting date in 2000. Equipment for irrigation decision-making consisted of electronic sensors measuring: climatic parameters, soil moisture, plant, trunk, and fruit. The trunk sensors measured the daily growth rate and maximum daily contraction (MDS). The fruit sensors measured the daily growth rate based-on climatic and soil conditions. The data collected was processed using special algorithms. 

The results were sent to the irrigation controller as “irrigation commands”.
