“…As a measure to cope with drought stress, producers have been adopting more and more irrigation practices. Currently, drip fertigation is increasingly preferred since it provides both water and nutrients to match crop demand and has the potential to manage both water and nutrients in a sustainable manner (Hartz and Hochmuth, 1996). Since tomato is a N sensitive crop, relatively low cost for fertilizer N and high price for tomato fruit could prompt farmers to over fertilize processing tomato, thus possibly causing environmental problems (Rinaldi et al, 2007).…”

Titnely sufficient water supply through drip irrigation or fertigation may increase nutrient demand of processing tomato {Lycopersicon esculentum Mill.) due to increases in yield production. However, excessive nutrient application could result in crop Itixury uptake and enrichment in soil profile, especially mineral N, with the latter potentially causing environmental concerns. A study was conducted to determine the responses of crop N utilization and post-harvest soil profile mineral N to fertilizer N and P additions under drip fertigated processing tomato in sandy loam soils from 2003 to 2005. Across the 3 yr, both fruit N removal and plant total N uptake were either linearly or quadratically related to fertilizer N rate, with 187 kg N ha" ' of fruit removal and 268 kg N ha" ' of plant total N uptake obtained at the maximum yield. Nitrogen uptake efficiency and apparent N recovery decreased linearly with increases in N rate. At the maximum fruit yield, N uptake efficiency was 0.71, and apparent N recovery was 51.7%. Post-harvest soil profile (0-100 cm) mineral N increased with increases in fertilizer N rate, and at greater rates with fertilizer N appHed at rates above those required for maximum fruit yield production. Of the soil residual N, 62% remained in the top 40-cm soil layer. Addition of fertilizer P had no effects on plant N uptake, N uptake efficiency and post-harvest mineral N in soil profile, presumably due to the high levels of soil test P. Beneficial management practices need to be developed to prevent soil N losses during the non-growing season following production of processing tomato with drip fertigation.

“…Fertigation intervals of 11-22 d did not affect yield in bell pepper (Storlie et al, 1995). Generally, it has been noted that the total amount of nutrient given over a certain time period is more important than the frequency of application (Hartz and Hochmuth, 1996).…”

The book series Advances in Olericulture provides a state-of-the-art account of research in olericulture, the applied life science of production and utilization of vegetable crops. The series focuses on various aspects of vegetable science and technology covering primarily but not exclusively species where the vegetative organ is the economically important component. The series of books spans current topics from sustainable fertilization to organic production; from open field cultivation to advanced soilless growing techniques; from vegetable seed and seedling physiology to vegetable quality and safety; from environmental stresses to phyllosphere communities interaction with vegetables; from postharvest biology and technology to minimally processing of vegetables. The series is designed to present the most advanced scientific information available linking basic and applied research for serving olericulturists, research workers, teachers and advanced students.More information about this series at
