“…The excess of the total yield under calcium application was 2.8%-8.6%, whereas that of the marketable yield was between 12.1% and 21.8%, as compared with the total yield (4.99 kg m -2 ) and the marketable yield (3.80 kg m -2 ) obtained from control plants. This conflicts with results reported in a study by Alexander and Clough (1998) and may be related to the additional effect of genetic (cultivar) and environmental (cultivation place) components. Similarly, data provided by Flores et al (2004) indicate that the application of calcium to the root environment did not cause significant changes in fresh or dry matter of pepper fruits.…”

“…Low Ca concentration in plant tissues is the main cause of various physiological disorders. One of the most frequently appearing disorders in pepper feeding in covered cultivation as well as in open fields, which happens in the period of most intense fruit growth, is blossom-end rot (BER), which destroys the usefulness of pepper, tomato, and eggplant fruits (Alexander and Clough, 1998;Paradiković et al, 2004Paradiković et al, , 2013Kowalska and Sady, 2012;Michałojć and Dzida, 2012). The main cause of this disorder is limited water absorption by plants, which is closely related to Ca transport (Morard et al, 2000;Suzuki et al, 2003;Cobanero et al, 2004).…”

Introduction Vegetables, which provide essential nutrients and healthpromoting elements, constantly remain in the area of interest of producers and consumers of so-called "healthy foods". The selection of vegetables cultivated for harvest of fresh material is very wide, and the diversity of products and biological components allows for great potentials of dietary compositions. Pepper (Capsicum sp.) is cultivated in many countries around the world as a precious vegetable with high biological value (Molnár et al., 2005; Wetwitayaklung and Phaechamud, 2011). The field cultivation of sweet pepper for fresh vegetable marketing as well as for processing has gained significant economic importance in Poland in recent years (Gajc-Wolska and Skąpski, 2002; Buczkowska, 2007; Gajc-Wolska et al., 2007). The unique taste quality and health-promoting properties of the fruit, conditioned by the presence of antioxidants and mineral components, contribute to the value of this vegetable in the human diet (Flores et al., 2004; Pokluda, 2004; Zaki et al., 2013). Obtaining a good marketable yield of sweet peppers from open field cultivation in less favorable conditions depends to a large extent on the choice of cultivar and on the application of treatments that enhance the yield (Buczkowska, 2007; Gajc-Wolska et al., 2007), including mineral feeding of plants and the level of feeding (Marín et al., 2009; Kowalska and Sady, 2012; Michałojć and Dzida, 2012). Proper mineral feeding of plants plays an important role in shaping their growth and development, as well as their size and quality of yield. In recent years, calcium has become more popular as its additional function of a secondary information transmitter was discovered. Calcium ion uptake by plants is to a large extent genetically conditioned. The process of Ca absorption, transport, and distribution in a plant is influenced by many soil, biological, and climatic factors (White and Broadley, 2003; Bouzo and Cortez, 2012; Shakoor and Bhat, 2014). Low Ca concentration in plant tissues is the main cause of various physiological disorders. One of the most frequently appearing disorders in pepper feeding in covered cultivation as well as in open fields, which happens in the period of most intense fruit growth, is blossom-end rot (BER), which destroys the usefulness of pepper, tomato, and eggplant fruits (Alexander and

“…Bell pepper plants benefited (increased fruit yields and reduced BER incidences) from Ca applications in 2005 (Table 6) but not in 2001 (Table 2). In drip-irrigated pepper grown in black plastic mulch, total yield of total marketable increased and yield of scalded fruit decreased with increasing Ca rate (Alexander and Clough, 1998). In a greenhouse study in Israel, the lowest BER incidence in bell pepper occurred with the most frequent irrigation and the highest Ca concentration in the nutrient solution (Bar-Tal et al, 2001).…”

Bell pepper (Capsicum annuum L.) plants have a high demand for water and nutrients. Water stress on bell pepper is associated with reduced yields and incidence of blossom-end rot (BER). High irrigation rates are commonly applied to maximize yields. Excessive irrigation rates, however, may negatively affect bell pepper plants. The objective of this study was to evaluate the effects of irrigation rates and calcium fertilization on plant growth and fruit yield and quality. Trials were conducted in the spring of 2001, 2003, and 2005 at the University of Georgia, Tifton Campus. Drip-irrigated bell pepper (‘Camelot’ or ‘Stiletto’) plants were grown on black plastic mulch. Plants were irrigated with rates that ranged from 33% to 167% of the rate of crop evapotranspiration (ETc). Results showed that irrigation at 70% ETc (2001), 67% ETc (2003), and 50% ETc (2003) were sufficient to maximize vegetative growth and fruit yield and provided yields similar to those at 100% ETc. Leaf net photosynthesis and stomatal conductance (gS) were reduced, and incidence of BER was increased with reduced irrigation rates (33% and 67% ETc). Incidences of soilborne diseases (Pythium spp. and Phytophtora capsici) tended to increase in plants receiving excessive irrigation rates (167% ETc). Irrigation rate also affected fruit quality; incidence of BER and fruit soluble solids were both increased at 33% ETc. Calcium fertilization had no effect on soil water content (SWC), plant growth, and incidence of soilborne diseases, and an inconsistent effect on fruit yield and incidence of BER. In conclusion, there is potential for use of irrigation at rates below 100% ETc. Reduced irrigation diminished the volumes of water applied and provided fruit yields similar to those at 100% ETc. Excessive irrigation rates (167% ETc or above) wasted water and resulted in both higher incidences of soilborne diseases and reduced bell pepper yields.

“…Plots receiving low frequency (LF) irrigation were irrigated monthly when fertilizers were applied (Figs. 1 and 2), except during the first 6 weeks after planting in 1992, when air temperatures Early and total yields of bell peppers can be increased with plastic mini-tunnels used early in the growing season (Alexander and Clough, 1998;Gaye et al, 1992aGaye et al, , 1992bWells and Loy, 1985). This improved crop performance has been attributed to the higher-than-ambient tunnel air temperatures contributing to accelerated plant growth and development (Gerber et al, 1988;Maurer and Frey, 1987).…”

Effects of staking, drip irrigation frequency and fertigated N rate on dry matter partitioning and yield of bell peppers (Capsicum annuum L.), grown using polyethylene mulch and mini-tunnels, were determined in two years. In the second year, which had higher early-season temperatures and more hours of direct sunlight, plants were larger, more productive and had larger fruit with thicker pericarps and a higher water content than in the first year. In both years, staked plants fertigated with 31.5 vs. 63 kg·ha-1 N produced higher yields due to increased fruit size and pericarp thickness. Compared with the response to monthly irrigation plus rainfall, additional irrigation applied when the soil moisture tension averaged below -25 and -20 kPa in the two years, respectively, affected yield only in the second year when it increased yield and the number of fruits produced by staked plants and decreased that of non-staked plants. Patterns of vegetative development and dry matter partitioning indicate that resources were remobilized from leaves to support fruit development.
