The aim of this study is to develop an integrated and micro-controller based electronic circuit which might be used in soilless agriculture smart greenhouse systems. In study, a novel system design proposed measure monitor parameters such as the desired ambient temperature, nutrient solution alkalinity (pH) conductivity greenhouse. addition design, control mechanism designed keep amount solutio...

One of the most important problems encountered in cultivation cut flower gladiolus is soil-borne diseases and pests. This problem substantially reduces yield quality. Soilless culture very limited for it has not been studied extensively. The characteristics growing media used soilless either directly or indirectly affect Therefore, quite essential to determine appropriate cultivation. At same t...

Soilless growing systems can improve water-use efficiency, especially in closed soilless systems. The main purpose of this study was to evaluate the effects different transplanting conditions, and determine how supplying H2O2 as an oxygen source rhizosphere strawberry plants a system affects plant growth, fruit yield quality. Strawberry (Fragaria x ananassa Duch.) cv. ‘Fortuna’ were cultivated ...

This research was performed to evaluate the effects of foliar application of nano-silicon (NSi), as a quasi-essential element, on yield, flower quality, vase life and infestation percentage of gerbera by greenhouse whitefly. Treatments were preharvest foliar application of different levels of NSi (0, 50 and100 mg/L) on gerbera 'Stanza' in a soilless system (to eliminate the effects of soil's Si...

Soilless tomato cultivation wastewater, with typically low COD, high concentrations of phosphorus, and oxidized forms nitrogen, may be effectively treated in a rotating electrochemical disk contactor (RECDC) bioelectrochemical reactor (BER), such as electrobiological (REBDC). The aim this study was to determine the technological parameters both reactors, i.e., electric current density (J) hydra...

A composite model was developed for water and mineral relations of greenhouse tomato (Solanum lycopersicum L.) cultivated in semi-closed or open soilless (rockwool) culture. The model simulated on a daily basis: (i) the evolution of crop leaf area index and water uptake using empirical equations; and (ii) the variations of ion concentrations and electrical conductivity (EC) in the recirculating...

With the aim of defining the best management of nutrient solution (NS) in a soilless system for obtaining high quality baby-leaf rocket, the present study focuses on two wild rocket genotypes ("Nature" and "Naturelle"), grown in a greenhouse under two Southern Italy growing conditions-autumn-winter (AW) and winter-spring (WS)-using two soilless cultivation systems (SCS)-at two electrical conduc...

Due to the econemic and envaironmental limitiation in the use of peat moss as a growth medium of ornamental plants, researchers seek an apporiate alternative in flower and plants industry. Zeolite because of the high capacity of water holding and cations enchange, has an ability in the replacement  of peat moss. At this research, the posibility subtitution of peat moss by zeolite as a growth me...
