Effect of Nitrogen and Ccalcium Concentration in Nutrient Solution on Growth, Yield and Tipburn of Butterhead Lettuce in Floating System
The present investigation was carried out to evaluate the impacts of different concentrations of N and Ca and N:Ca ratio in nutrient solution on growth indices, yield and tipburn of butterhead lettuce (Lactuca sativa var. Capitata) in floating system. The experiment was conducted as completely randomized design, with 8 treatments and 3 replications, in Research Greenhouse of Shahrekord Universi...
متن کاملEstimates of Soil Solution Ionic Strength and the Determination of pH in West Australian Soils
The average ionic strength of 20 West Australian soils was found to be 0·0048. The effects of three electrolytes (deionized water, CaCl2 and KN03), three ionic strengths (0'03. 0·005 and soil ionic strength at field capacity, Is) and two soil liquid ratios (1:5 and 1:10) on the pH of 15 soils were investigated. pH measurements in solutions of ionic strength 0·005 differed the least from measure...
متن کاملOptimal Solution in a Constrained Distribution System
We develop a method to obtain an optimal solution for a constrained distribution system with several items and multi-retailers. The objective is to determine the procurement frequency as well as the joint shipment interval for each retailer in order to minimize the total costs. The proposed method is applicable to both nested and non-nested policies and ends up with an optimal solution. To solv...
متن کاملElectrical Conductivity of Nutrient Solution, Plant Growth and Fruit Quality of Soilless Grown Tomato
Tomato plants (cv. Naomi) were grown until the 8 cluster in a greenhouse during Aug. 1998 – Jan. 1999 using a closed sub-irrigated soilless system. Plants were raised in pots (10 L) filled with peat and pomice (1:2 v:v) substrate. Forty days after transplanting 3 nutrient solutions (NS) with electrical conductivity (EC) of 2, 4, and 6 dS/m were applied to the plants. The ECs were achieved by pr...
متن کاملThe interaction of actin with myosin and heavy meromyosin in solution at low ionic strength.
The interaction of actin with myosin and heavy meromyosin was studied in the presence of Mgf+ ion and adenosine triphosphate at low ionic strength. When the heavy meromyosin ATPase was 17-fold activated by actin, the actoheavy meromyosin complex responsible for this activation did not give rise to a measurable increase in the viscosity of the sample above that predicted for a noninteracting mix...
