Allometric 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 کاملCorn-Residue Transformations into Root and Soil Carbon as Related to Nitrogen, Tillage, and Stover Management
Recent studies of SOC storage and turnover have employed 13C natural abundance ( 13C) as an in situ Soil organic carbon (SOC) is sensitive to management of tillage, marker of relic and recent SOC pools. Mass concentraresidue (stover) harvest, and N fertilization in corn (Zea mays L.), tions of SOC and the 13C signature are sufficient to but little is known about associated root biomass includin...
متن کاملApplication of the nitrogen-tillage-residue-management (NTRM) model for corn grown in low-input and conventional agricultural systems
Radke, J.K., Shaffer, M.J., Kroll, K.S. and Saponara, J., 1991. Application of the nitrogentillage-residue-management (NTRM) model for corn grown in low-input and conventional agricultural systems. Ecol. Modelling, 55: 241-255. Unlike many conventional agricultural systems, low-input management techniques minimize the use of nutrients and pesticides produced off the farm. This study evaluates t...
متن کاملeffect of tillage, wheat (triticum aestivum l.) residue & nitrogen management on corn (zea mays) yield and yield components
abstract conservation tillage practices integrated with appropriate residue management is an efficient approach in sustainable agriculture to prevent the removal or burning of crop residues. two years field experiments were conducted to evaluate the effect of wheat residue management on yield, yield component and morphophysiological characteristics of corn. experimental design was split plot us...
متن کاملPopulation Dynamics of Heterodera glycines in Conventional Tillage and No-Tillage Soybean/Corn Cropping Systems.
The effects of no-tillage (NT), conventional tillage (CT), and crop rotation on soybean yield and population dynamics of Heterodera glycines were compared during a 7-year study in a silty clay loam soil with 6% organic matter. Either H. glycines-resistant 'Linford' soybean or susceptible 'Williams 82' soybean was rotated with corn and grown on 76-cm-wide rows in both tillage systems. Soybean wa...
