The PHYTOGRAM NETWORK is an integrated method of sensing crop status, transferring this status to the farm headquarters by radio telemetry and setting irrigation pump site conditions, also by radio telemetry. The network was operated for sensing and transfer only in 1986 on eight commercial fields in central Arizona. The difference in the cotton response of furrow irrigated versus drip irrigated fields, genetic differences in the PHYTOGRAMS from various cotton varieties and response of cotton to salt shock are discussed.
