Assessing Photosynthetic Leaf Area of Corn under Different Tillage Systems and Soil Zones
The photosynthetic leaf area may be influenced by soil texture. The objective of this experiment was to evaluate photosynthetic leaf area under different soil textures, based on soil electric conductivity (EC) measurements, tillage systems, and N rates in dryland corn (Zea mays L.) from 2007 to 2009. A commercially available soil electric conductivity (EC) measurement system (Veris Technologies...
متن کاملEffects of Deep Tillage and Straw Returning on Soil Microorganism and Enzyme Activities
Two field experiments were conducted for two years with the aim of studying the effects of deep tillage and straw returning on soil microorganism and enzyme activity in clay and loam soil. Three treatments, (1) conventional tillage (CT), shallow tillage and straw returning; (2) deep tillage (DT), deep tillage and straw returning; and (3) deep tillage with no straw returning (DNT), were carried ...
متن کاملAllometric relationship between some morpho-physiological characteristics of corn under different tillage systems and sowing dates
ABSTRACT- Field experiments were conducted to determine the relationship between plant leaf area as the dependent variable with leaves number, leaf dry weight, and total vegetative components dry weight and plant height as the independent variables. Treatments were two tillage systems (conventional and no-tillage) as main plots, and seven sowing dates (11 May, 18 May, 25 May, 1...
متن کاملEffect of Clinoptilolite Addition on Bacterial Counts in Pig Slurry
The aim of this study was to determine the effect of natural zeolite (commercial preparation with 80% of clinoptilolite) on counts of different physiological groups of bacteria i.e. sulfide-producing, faecal and total coliform, mesophilic aerobic and anaerobic, and thermophilic bacteria in pig slurry. Zeolite was spread daily directly over partially slatted floor in a dose of 0.4 kg/1 m 2 durin...
