The effectiveness of varying rates and timing of applied primary plant nutrients as a completely soluble N-P-K fertilizer through a drip/trickle low volume irrigation system was studied during 1991 on eggplant (Solanum melongena cv. Harris Special Hibush). Before the drip irrigation tubing and black plastic mulch were laid on a coastal plain sandy loam soil, plots were treated with 0, 22, 45, and 67 kg ha-1 of nitrogen (N), phosphate (P2O5) and potash (K20). The higher rates of preplant fertilization did have a significant beneficial effect on total seasonal yields of quality eggplants. The preplant treatments also had an influence on mid and late season production. As the frequency of drip/trickle applied primary plant nutrients increased up to 6 seasonal applications, the total quality fruit production substantially increased. Frequency of applications also had an influence on seasonal yields. Applying increased rates of the primary plant nutrients at a low seasonal frequency of 3 applications had little influence on increasing total quality yields of eggplants. Individual quality fruit was significantly heavier from plants which received 5 to 6 applications of the soluble N-P-K fertilizer than from plants which received no fertilizer through the drip/trickle irrigation system for the season.
Producers of floriculture crops strive to cultivate compact and healthy plants that are considered high quality and attractive for consumers. The fertilization regimen has a significant role in the ultimate appearance and robustness of a crop. Many
of horticultural crops to design fertilization programs to achieve high yields ( Snyder, 1998 ). Tissue analysis complements soil analysis by reflecting the amounts of nutrients present in the soil that were actually taken up by the root system and
both important, the most critical parameter for pollination is the number of pollen tubes reaching the base of the style and fertilizing the egg cell. Temperature ( Petropoulou and Alston 1998 ; Yoder et al., 2009 ) and pollinizer selection

Tea [ C. sinensis (L.) O. Ktze] is a kind of traditional economic crop in southern China, and tea industry can quickly promote the local economy development ( Zhang et al., 2010 ). Fertilization is an effective way to supply nutrients for tea tree
Hydroponics is an increasingly important field for counterseason vegetable production because of its efficiency in fertilization, water, and space use. Furthermore, it can overcome the disadvantages of soil culture, such as continuous cropping
