Effects of fertigation regime on blossom end rot of vegetable fruits | English | Asher Bar-Tal and Benny Aloni

The relationships between blossom end rot (BER) of vegetable fruits and fertigation regimes are reviewed. Many fruit disorders are affected by nutrient deficiencies or unbalanced nutrition: BER, gold specks, green back, blotchy ripening, color spots, malformation, hollowness and fruit cracking. Numerous studies have shown that BER is a mineral disorder and that its occurrence could be reduced by improving the supply of specific nutrients. The sensitivity of vegetable  fruits to BER varies greatly among cultivars,   environmental conditions and fertigation regimes. Some interactions between environmental conditions and fertigation regime are presented. The relation between BER and Ca nutrition is described and discussed in detail. The possibility that Mn may also play a role in the development of BER is discussed.

Fertigation-chemigation in protected agriculture | English | I. Papadopoulos

Fertigation-Chemigation are regular and widely accepted practices for fertilization and plant protection under protected agriculture. With fertigation, the nutrients in the form og soluble fertilizers anticipated to most crops needs according to their stage of development, are applied with the irrigation water. The application of plant protectants through irrigation system such as herbicides, fungicides, insecticides, nematicides, growth regulators and bio control agents has been also expanded rapidly during the last few decades.   However, the application of any chemical to soil and crops may have envarionmental implications, in this work crtical thecnical aspects, the current knowladge anf futuer prospects of fertigation-chemigation for crops yield and improve quality on degradation-free and sustainable basis, are presented.

Fertigation recipes for selected crops in the Mediterranean region | English | I. Papadopoulos, C. Metochis and N. Seraphides

Fertigation increases efficient use of water and fertilizers, produces higher yields, improves quality of the production and protects environment. To ensure uniform distribution of water and fertilizers, the irrigation system must be properly designed and operated. The choice of suitable fertilizers is also very important and must be based on several factors like nutrient form, purity, solubility and cost. To implement a fertigation program, particularly  under intensive greenhouse production, good knowledge is required of water and nutrient requirements over the growing season. The fertigation model developed to be used at farmers level concerns drip-irrigated greenhouse tomato, pepper, cucumber and melon. It takes into account the amount of nutrients which may be available to the crop from soil and calculates for a target yield the quantities of N, P and K fertilizers which may be supplied through the irrigation stream over the growing season.
