Foliar application has been widely used and accepted as an essential part of crop production, especially on horticultural crops. Although not as widespread on agronomic crops, the advantages of foliar application have been well recognized and ever-increasing efforts have been made to achieve steady responses. For instance, foliar application was earlier thought to damage tomatoes but has become standard practice. The absorption takes place through their stomata and epidermis. Plants are also able to absorb nutrients through their stems. The purpose of foliar application is to supplement soil fertilization. Supplying a plant’s major nutrients (nitrogen, phosphorus, and potassium) through soil application will remain the major path. However, foliar application has proven to be an excellent method of supplying plant requirements for secondary nutrients (calcium, magnesium, and sulfur) and micronutrients (zinc, manganese, iron, copper, boron, and molybdenum), while supplementing N-P-K needs for short or critical growth three-stage periods. Foliar application has been shown to avoid leaching from soils and prompts a quick reaction in the plant.


To study the behavior of foliar application on selected experiments in northern and middle belt of Ghana, an intern is needed to analyze data collected from several on-station and on-farm trials conducted in northern Ghana, Bono East, Bono and Ahafo regions of Ghana.

Specifically, the intern will determine among the following

  1. Effect of the foliar application of the micro-nutrients on yield and yield components of rice
  2. Any correlation between foliar and soil fertilizer applications of same micro-nutrients
  3. Analyze spatially effect of the foliar and soil applied micro-nutrients
  4. Undertake regression and correlational analysis


This student shall analyze agronomic data collected from several on-station and on-farm trials in the Northern and North East regions of Ghana as well as Bono East, Bono and Ahafo regions of Ghana. With support of the FERARI team, the intern shall be required to provide a clear study methodology including analytical procedures for this research.


At the end of the research, the student shall produce a thesis, policy brief and a report to FERARI on this research. Furthermore, the intern would be required to produce a research article that can be published in a scientific journal for our wider international audience.


The duration for this assignment shall be seven (7) months (first month for inception proposal, second and third month for the design of research instruments and field data collection and the remaining four months for data analysis, report writing and research article drafting.

Selection procedure
