“…These results were consistent with the study of Chanthai et al (2013) [2] who compared fertigation with solid fertilizer applicationunder the same environmental conditions and soil as this experiment. They reported that the fertigation promoted faster growth and resulted to more tomato dry matter and yield compared to solid fertilizer application.…”

“…Leaching is the main fertilizer loss as the soil is sandy with low water holding capacity. Chanthai et al [2] compared fertigation and solid fertilizer application for tomato production under drip irrigation system. They prevented leaching of fertilizer by controlling irrigated water at root zone and covered the soil with plastic sheet to prevent excessive rain fall.…”

Abstract-Fertigation is widely adapted for tomato production in Thailand as it is an efficient method for fertilizer application. However, its mechanism, especially the influence on root and plant nutrient distribution which is the critical aspect for nutrient uptake, has been rarely reported. A field experiment was conducted during the dry season in 2013 to investigate the impact of fertigation on tomato root and plant nutrient distribution in the soil profile. Fertigation and conventional (solid) fertilizer application with the same amount of nutrients and duration of application were compared under drip irrigation system. The results showed that fertigation was more efficient than solid fertilizer application, resulting in better growth, higher fruit yield and fertilizer use efficiency. The results also indicated that fertigation had a better root system than solid fertilizer application. The roots under fertigation distributed more vertically and horizontally than those under solid fertilizer application. Fertigation produced more small roots (0.01-1.00 mm) and medium roots (1.01-2.00 mm) but less large roots (2.01-3.00 mm) than solid fertilizer application. More distribution of available form of primary nutrients (N, P and K) to root zone was also found under fertigation system. Tomato is an important economic vegetable in Thailand. In 2012, total growing area was about 6,280 ha [1]. Its growing area is mainly in the Northeast. The average yield is very low (20.7 t ha -1 ) due to poor management practices, plant pests and unfavorable environmental conditions. Furrow irrigation system used to be a common practice for the tomato growers in this area. The major drawback of furrow irrigation is its ineffectiveness in the coarse texture soil with low water use efficiency. Drip irrigation as the most efficient irrigation method is rapidly expanding and highly recommended in this area.Beside water application, solid fertilizer application (common practice for farmers) in this area is ineffective. Leaching is the main fertilizer loss as the soil is sandy with low water holding capacity. Chanthai et al.[2] compared fertigation and solid fertilizer application for tomato production under drip irrigation system. They prevented leaching of fertilizer by controlling irrigated water at root zone and covered the soil with plastic sheet to prevent excessive rain fall. Y.

Wonprasaid* is with Institute of Agricultural Technology, Suranaree University of Technology, Nakhon Ratchasima, 30000, Thailand They found that fertigation produced greater tomato yield and nutrient use efficiency than solid fertilizer application with the same amount of nutrients. In their experiment, fertilizer was applied only 2 times for the solid fertilizer application treatment while for fertigation treatment fertilizer was applied 8 times. The more efficiency of nutrient application under fertigation th...

“…Tomatoes are cultivated in a plastic mulched/drip irrigated production system. In all farms, drip irrigation for tomatoes has gained popularity because of water-use efficiency and because it allows for the application of fertilizers in irrigation water, leading to greater tomato yield and efficiency of fertilizer use than soil application methods [31][32][33]. During winter, a single daily irrigation suffices, whereas, as spring approaches, the number of daily irrigations is usually 4-5, only one of which also provides fertirrigation.…”

Economic Sustainability of Italian Greenhouse Cherry Tomato

Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, both from the perspective of the farm, as well as from that of the entrepreneur, the aim of this paper was to analyze the economic sustainability of Sicilian greenhouse cherry tomato cultivated in the Ragusa Province. In particular, an economic analysis on 30 representative farms was conducted in order to estimate production costs and profits of greenhouse cherry tomato. According to our results, the lack of commercial organization, which characterizes the small farms we surveyed, determines low contractual power for farmers and, consequently, low profitability.
