Growth Regulation of Arable Crops

1986
Plant growth regulators (PGRs) are increasingly used as part of the farmer’s strategic chemical management of cereals and other arable crops. Over the past decade yields per hectare of wheat and barley have virtually doubled as improved varieties, intensified use of fertilizers and agrochemical sprays have been adopted.

Spray Retention Models for Arable Crops

Journal of ASTM International, 2006
A model has been developed explaining 92 % of the variance in spray retention by individual plants. The effects of formulation and plant morphology were represented as a logistic function, because this can accommodate retention close to 100 or 0 % whereas an additive model cannot. All inputs for the current model, except for the plant morphology factor,
