Book Description
The burgeoning demand on the world food supply, coupled with concern over the use of chemical fertilizers, has led to an accelerated interest in the practice of precision agriculture. This practice involves the careful control and monitoring of plant nutrition to maximize the rate of growth and yield of crops, as well as their nutritional value.

Book Description
The effects of planting date on mineral element concentration in sweet corn (Zea mays L. cv. Jubilee) at six developmental stages and on yield were investigated. Planting dates were chosen to correspond to early, mid-season, and late commercial plantings. Two nitrogen rates were applied since nitrogen is more often limiting than any other nutrient for sweet corn grown in Western Oregon. Boron was also applied since it has been shown to be limiting in many other crops grown in the Willamette Valley. Planting date significantly affected N, P, K, Ca, Mg, Mn, Fe, Cu, B, and Zn concentration in the whole plants during the vegetative growth stages and in the ear leaves during the stages between tasseling and harvest. During the early stage of growth, N, P, K, Ca, Mg, B, and Zn tended to be higher in the early planted corn plants, while later in the development of corn the effects of planting date were more variable. Planting date also affected the fresh and dry weight of whole plants; the later planting produced more dry weight than the earlier two plantings, while the early planted corn produced more fresh weight at harvest than the later two plantings. Consequently, when analyzing sweet corn for nutritional status, date of planting should be considered when interpreting the plant analysis data. The application of B had no effect on yield, fresh weight or dry weight and only increased B concentration at the first developmental stage. The additional application of N, did not significantly increase yield for the late planted corn, but did for early planted corn. N concentration, as well as Mg, Mn, Cu, and Zn concentrations increased with the higher rate of N fertilizer applied (125 kg/ha). Fresh weight and dry weight were both higher in the plants receiving the higher rate of N, with the difference becoming greater as the plants matured.
