“…The low macronutrient concentration (N, P, and K) recorded in the current study under water stress conditions could be attributed to a decrease in soil moisture content in the root zone (Table 6). Those results are consistent with the findings of Simonne et al (1998), Kirnak et al (2001Kirnak et al ( , 2002, and Kaya et al (2003) who reported for several vegetable crops that water stress has a wider role in reducing leaf macronutrient concentrations.…”

Limited water supply in the Mediterranean region is a major problem in irrigated agriculture. Grafting may enhance drought resistance, plant water use efficiency, and plant growth. An experiment was conducted in two consecutive growing seasons to determine yield, plant growth, fruit quality, leaf gas exchange, water relations, macroelements content in fruits and leaves, and water use efficiency of mini-watermelon plants [Citrullus lanatus (Thunb.) Matsum. and Nakai cv. Ingrid], either ungrafted or grafted onto the commercial rootstock ‘PS 1313’ (Cucurbita maxima Duchesne × Cucurbita moschata Duchesne), under open field conditions. Irrigation treatments were 1.0, 0.75, and 0.5 evapotranspiration rates. In both years (2006 and 2007), marketable yield decreased linearly in response to an increase in water stress. When averaged over year and irrigation rate, the total and marketable yields were higher by 115% and 61% in grafted than in ungrafted plants, respectively. The fruit quality parameters of grafted mini-watermelons such as fruit dry matter and total soluble solids content were similar in comparison with those of ungrafted plants, whereas titratable acidity, K, and Mg concentrations improved significantly. In both grafting combinations, yield water use efficiency (WUEy) increased under water stress conditions with higher WUE values recorded in grafted than ungrafted plants. The concentration of N, K, and Mg in leaves was higher by 7.4%, 25.6%, and 38.8%, respectively, in grafted than in ungrafted plants. The net assimilation of CO2, stomatal conductance, relative water content, leaf, and osmotic potential decreased under water stress conditions. The sensitivity to water stress was similar between grafted and ungrafted plants, and the higher marketable yield from grafted plants was mainly the result of an improvement in nutritional status and higher CO2 assimilation and water uptake from the soil.

“…Rouphael et al (2008) reported that under water stress conditions, higher concentration of K and Mg were observed. Some researchers stated that the high irrigation levels resulted in decreased mineral nutrient contents (Simonne et al 1998;Kirnak et al 2001;Kaya et al 2003;Rouphael et al 2008). B content was decreased with the increasing irrigation water (I 55 , I 70 , I 85 and I 100 ).…”

The present study was conducted to determine the effects of deficit irrigation (I) (I 100: full irrigation; I 85 : 15% deficit; I 70 : 30% deficit; I 55 : 45% deficit and I 40 : 60% deficit) on mineral nutrient contents of fresh sweet corn (Zea mays saccharata) grain in two vegetation seasons, years of 2011 and 2012, in Isparta ecological conditions. The experiment was set up according to the Randomized Complete-Block Design with three replicates. The species of Lumina F 1 was used as the sweet corn cultivar. The results revealed statistically significant effects of water deficit on mineral nutrient contents of fresh sweet corn grain. The highest nitrogen content (2.29% in 2011 and 2.32% in 2012), the highest phosphorus content (0.332% in 2011 and 0.331% in 2012), the highest potassium content (0.855% in 2011 and 0.837% in 2012), the highest calcium content (0.031% in 2011 and 0.029% in 2012), the highest magnesium content (0.123% in 2011 and 0.132% in 2012), the highest iron amount (27.27 mg kg-1 in 2011 and 26.12 mg kg-1 in 2012), the highest copper amount (3.99 mg kg-1 in 2011 and 4.12 mg kg-1 in 2012) and the highest manganese amount (10.92 mg kg-1 in 2011 and 11.68 mg kg-1 in 2012) were obtained from the "I 70 " irrigation level. The highest zinc amount (34.77 mg kg-1 in 2011 and 30.14 mg kg-1 in 2012) and the highest boron amount (5.389 mg kg-1 in 2011 and 5.306 mg kg-1 in 2012) were determined in I 85 and I 40 irrigation levels, respectively. Generally, the mineral nutrient contents were increased with water deficit up to a certain level "I 70 " and he lower irrigation levels (I 55 and I 40) than "I 70 " resulted in decreased mineral nutrient contents, except for B, of sweet corn in both years.

“…Excess addition of mineral nitrogen fertilizers causes a major series problem for environment and contamination the underground water as well as led to an accumulation the edible parts (Al-Gosaibi, 1994;Badiane et al, 1994). Many investigators noticed that mineral nitrogen had an important role for enhancing growth characters of sweet pepper plants (Qawasmi et al, 1999;Palada et al, 1999 andByoung Ryong., 1999), chlorophyll content, N, P and K contents in plant foliage (Simonne et al, 1998), flowering, fruit characters and quality (Maya et al, 1997), number of fruits (Palada et al, 1999) and total yield (Palada et al, 1999). Furthermore, NPK fertilizers play a significant role in successful tomato production (Jack et al, 2006).…”

Two field experiments were performed at El-Baramon, Experimental Station, Dakahlia Governorate, Egypt, during the successive seasons of 2007 and 2008 to study the effect of boron foliar nutrition and different combinations of mineral and organic nitrogen fertilization on growth, chemical composition and yield of sweet pepper cv. California wonder. The main results could be summarized that: 1-Foliar application of boron at 100 ppm and fertilization with 75% mineral nitrogen fertilizer + 25% organic nitrogen resulted significasnt increase of plant height, number of branches, fresh and dry weight. 2-The highest significant values of A, B, total chlorophyll and carotene as well as N, P, K and Ca contents in sweet pepper plant leaves were obtained with foliar addition of boron at 100 ppm and fertilization with 75% mineral nitrogen + 25% organic nitrogen. 3-Fruit sitting percentage, number of fruits per plant, average fruit weight, fruit yield per plant and total yield per feddan were significantly increased as a result of foliar addition with boron at 100 ppm and fertilization at level of 75% mineral nitrogen fertilizers + 25% organic nitrogen. 4-Foliar nutrition of boron at 100 ppm and fertilization by 75% mineral nitrogen + 25% organic nitrogen significantly increased fruit length, fruit diameter, fruit flesh thickness, fruit dry weigh and TSS as well as vit C. In general, this study demonstrated that it is possible to produce highest growth, yield and quality of sweet pepper fruits by foliar application with boron at 100 ppm and fertilization using 75% from the recommended dose as mineral nitrogen plus 25% from the recommended dose as organic nitrogen.
