Furrow irrigation has about a 30% variation in yield across a field should this improve with LM & CP?
With finely tuned management of CPLM’s for Uniformity (>90%), irrigation scheduling that accounts for soil type variations and a soil surface managed to improve infiltration of water that minimises run off – yes the yield variation across the field should be less than traditional furrow irrigation. But management is the key. Generally, growers who have converted will find much less variation in crop yield across their CP&LM fields. However the variation in yield across furrow irrigated fields can usually also be improved through better management.
