“…2C, D). The inhibition of K + uptake by NaCl has been observed previously in glycophyte plants (Gouia et al, 1994;Shabala, 2000;Tarakcioglu and Inal, 2002). There is the competition between Na + and K + at the intracellular level, as the two ions could be transported by a common protein (Niu et al, 1995).…”

“…Kara and Keser (2001) also observed reduction in K/Na ratio of maize plants by increasing the NaCl salinity. Tarakcioglu and Inal (2002) reported a marked decrease in K/Na ratio of lettuce plants by increased concentration of NaCl and/or Na in a solution culture experiment. Reduction of K uptake in plants by Na is a competitive process (Grattan and Grieve 1999).…”

To examine the effects of subsoil NaCl salinity in relation to water stress imposed at different growth stages, wheat was grown in a heavy texture clay soil (vertosol) under glasshouse conditions in polythene lined cylindrical PVC pots (100 cm long with 10.5 cm diameter) with very low salinity level (EC e 1.0 dS/m; ESP 1.0 and Cl 30 mg/kg soil) in top 10 cm soil (10-20 cm pot zone) and low salinity level (EC e 2.5 dS/m, ESP 5, and Cl 100 mg/kg soil) in top 10-20 cm soil (20-30 cm pot zone). The plants were exposed to three subsoil salinity levels in the 20-90 cm subsoil (30-100 cm pot zone) namely low salinity (EC e : 2.5 dS/m, ESP: 5, Cl: 100 mg/kg soil), medium salinity (EC e : 4.0 dS/m, ESP: 10, Cl: 400 mg/kg) and high salinity (EC e : 11.5 dS/m, ESP: 20, Cl: 1950 mg/kg) in the subsoil (20-90 cm soil layer: 30-100 cm pot zone). Watering of plants was withheld for 20 days commencing at either early booting or anthesis or mid grain filling, and then resumed until maturity, and these treatments were compared with no water stress. Water stress commencing at anthesis stage had the most depressing effect on grain yield and water use efficiency of wheat followed by water stress at grain filling stage and early booting stage. High subsoil salinity reduced grain yield by 39.1, 24.3%, and 13.4% respectively in plants water-stressed around anthesis, early booting, and mid grain filling compared with 36.6% in wellwatered plants. There was a significant reduction in root biomass, rooting depth, water uptake and water use efficiency of wheat with increasing subsoil salinity irrespective of water regimes. Plants at high subsoil salinity had 64% of their root biomass in the top 0-30 cm soil and there was a marked reduction in subsoil water uptake. Roots also penetrated below the non-saline surface into salinised subsoil and led to attain high concentration of Na and Cl and reduced Ca/Na and K/Na ratio of flag leaf at anthesis stage. Results suggest that high subsoil salinity affects root growth and water uptake, grain yield and water use efficiency even in well water plants. Water stress at anthesis stage had the most depressing effect on wheat.

“…At 105 DAP, NR activity produced higher induction of NO 3 -, Mo, and the combination of both factors, while endogenous NR activity diminished (Table 4). This occurred presumably because the crop was in the maturation phase; furthermore, the NR activity varied according to the physiological age of the tissue, levels of water, light intensity, N source, temperature, and the levels of Mo, iron, and sodium (Tarakcioglu and Inal, 2002). An increase in the amount and activity of NR leads to a corresponding increase in the potential for nitrate reduction and confers a greater capacity for general aminoacid synthesis, protein synthesis, or total N assimilation (Ruiz et al, 2000).…”

In conventional agriculture, heavy doses of chemical fertilizers and pesticides are often used to improve the yield of various horticultural crops. These chemical fertilizers and pesticides cause health problems among consumers. Due to the adverse effects of chemical fertilizers, there is interest in the use of organic fertilizers. It has long been recognized that the rate-limiting step for nitrogen assimilation, the reduction of NO 3 -to NO 2 -catalyzed by nitrate reductase (NR), is highly regulated. An increase in the amount and activity of NR leads to a corresponding increase in the potential for nitrate reduction and confers a greater capacity for general amino-acid synthesis, protein synthesis or total nitrogen assimilation. The aim of the current experiment was to determine the effect of organic and conventional fertilizers on yield and nitrate reductase activity in saladette tomato.Tomato plants were grown under controlled greenhouse conditions and treated with either organic or conventional fertilizer. We evaluated five treatments: F1, sand + inorganic fertilizer; F2, sand + vermicompost tea; F3, a 1:1 mixture of sand: compost + vermicompost tea; F4, a 1:1 mixture of sand: vermicompost + vermicompost tea; and F5, a 2:1:1 mixture of sand: compost: vermicompost + vermicompost tea. The evaluated variables were yield, fruit size, number of fruits, fruit quality, chlorophyll content, and in vivo nitrate reductase enzyme activity. Fertilizer type strongly influenced the yield, fruit size, and fruit quality. The best organic fertilizer for tomatoes was sand + vermicompost tea. Tomatoes in this treatment group produced the second highest yield, the best NO 3 -assimilation, the greatest nitrate reductase enzyme activity, and the second highest organic foliar nitrogen content.
