Feeding the Crop: Plant Nutrition in Relation to Growth and Fruiting

Thomas A. Kerby


Close monitoring of the crop is becoming more common in today's era of new technologies. A University of California bulletin which describes in detail the growth and development of Acala cotton will be available in March. Growth is expressed on the basis of heat units (60F low threshold-triangulation method).

When nutrient uptake, concentration in the various plant tissues, and distribution between vegetative and reproductive growth is considered, better fertility management practices will be possible. The published work of Dr. Bassett (Agron. J. 62: 299-303. 1970) was used for calculations of nutrient concentration in the various plant tissues. The dry weight uptake and distribution by plant part data to be published in the upcoming UC Bulletin, when multiplied by Bassett's nutrient concentration data, form the data to be presented in this discussion.
