AbstractThe aim of this study was to investigate the response of sweet pepper (Capsicum annuum L.) to saline irrigation water and various irrigation regimes. The experiments were conducted in a greenhouse with two sweet pepper varieties (ONUR F1 and ADA F1) over two cropping seasons: Spring and Autumn on the Mediterranean coast at Antalya, Turkey. The irrigation regimes comprised four levels of Class A pan-evaporation and were applied using a drip irrigation system when evaporation reached a target value of around 10 mm. These four levels represented 0.50, 0.75, 1.00 and 1.25 of Class A panevaporation. In each irrigation regime the sweet pepper plants were exposed to four salinity treatments with electrical conductivities of 1.0, 2.5, 3.5 and 6.0 dS m -1 respectively. The study showed that both pepper varieties generally performed in a similar manner (except in terms of vegetative biomass production). The amount of salt accumulation within the root-zone was higher in Spring compared to Autumn; and therefore related to the total amount of irrigated water usage between seasons due to climatic variability. Increased salinity induced higher levels of salt accumulation within the pepper plant's root-zone, while an increased amount of saline irrigation water increased the size of the affected layer within the root-zone. Overall, an increased level of salinity alongside increased irrigation considerably depressed both vegetative growth and yield. Higher irrigation water productivities were attained with a regime comprising 0.50 of Class A pan-evaporation and which appeared to fulfil crop water requirements. It was found that sweet pepper varieties ONUR F1 and ADA F1 are moderately sensitive to salinity with a threshold value of 1.43 dS m -1 and a decreasing slope value of 11.1%.Although both seasons revealed a single salinity response function, there were considerable differences in the actual fresh pepper yield. This study demonstrates that for pepper crops irrigated with saline water (or grown on salt-affected soils), pepper growers must consider the salinity response function and seasonal productivity alongside an appropriate irrigation regime.Keywords: Capsicum annuum L.; class A pan-evaporation, modelling; sweet pepper varieties; salinity response function; salinity tolerance index, season; irrigation water productivity; yield. 2 IntroductionPepper (Capsicum annuum L.) is a high-value crop cultivated in many parts of the world (DeWitt and Bosland, 1993).

“…For operators taking place in Kumluca town, which is the widest greenhouse production centre of Antalya, inefficiency seemed to increase. This can also be attributed to saturation level of the town and declining yields due to overuse of lands (Yilmaz et al, 2010). Despite, producers in eastern Antalya -Serik seemed to demonstrate lower inefficiencies.…”

Agricultural production and income are important for Mediterranean region of Turkey. The region and especially Antalya province is well-known with greenhouse production. For greenhouse production achieving sustainability is important for meeting domestic and foreign demand and security of production lands. In order to measure the potential for improving greenhouse operators 281 farmers were surveyed in 2015 in Antalya and profit inefficiency and factors affecting inefficiencies of operators were estimated using stochastic frontier approach. Accordingly, the average inefficiency level of operators was found as 57 %, signifying the potential for improvement. The main objective was to undermine the impact of landownership on this inefficiency level. Yet, the impact of other relevant factors referring to greenhouse structures and famers' characteristics were estimated as well. While level of education seemed to reduce inefficiency, household size had appeared as an inefficiency rising factor referring to professional labour endowment of greenhouse production in Antalya. Being renter of land appeared as an inefficiency rising factor as well as holding plastic house or having located in the western parts of Antalya. These findings indicated importance of supporting improved production technologies and use of strengthened structures. In addition, it appeared as essential to provide incentives to renters to cope with their costs.

Greenhouses are a typical example of peri-urban land-use, a phenomenon that many planning systems find difficult to address as it mixes agricultural identity with urban appearance. Despite its urban appearance, greenhouse development often manages to evade urban containment policies. But a ban on greenhouse development might well result in under-utilisation of the economic value of the sector and its potential for sustainability. Specific knowledge of the urban and rural character of greenhouses is essential for the implementation of planning strategies. This paper analyses Dutch planning policies for greenhouses. It concludes with a discussion of how insights from greenhouse planning can be applied in other contexts involving peri-urban areas.
