evaluation of the aquacrop and ceres-maize models in assessment of soil water balance and maize yield
importance of fresh water in agriculture along with the essential demand of the growing population for food, indicates an extreme necessity of the optimum use of water. to this end, plant growth simulation models have been introduced in agricultural sciences to reach maximum yields in varying climates. variations in the of developed models cause difficulties for the unprofessional users. the aq...
متن کاملMaize response to water, salinity and nitrogen levels: soil and plant ions accumulation
In the present study, some nutritional imbalances, specific ion toxicity and yield-ion concentration relationships in maize under water, nitrogen (N) and salinity stresses were assessed. Effect of different levels of irrigation water (I1=1.0ETc+0.25ETc as leaching, I2 =0.75I1 and I3 =0.5I1) as main plot, salinity of irrigation water (S1=0.6, S2= 2.0 and S3=4.0 dS m-1) as sub-plot and N fertiliz...
متن کاملEvaluation of the CERES-Maize water and nitrogen balances under tile-drained conditions$
The CERES-Maize model was developed to investigate how variations in environmental conditions, management decisions, and genetics interact to aect crop development and growth. A tile drainage subroutine was incorporated into CERES-Maize to improve soil-water and nitrogen leaching under subsurface tile drainage conditions. The purpose of this work was to evaluate the soil-water, soil-nitrogen, ...
متن کاملModification of a maize simulation model under different water, nitrogen and salinity levels
Irrigation, salinity and nitrogen (N) are the three major limiting environmental factors inmaize yield potentials especially in arid and semi-arid regions. An integrated water and N MaizeSimulation Model (MSM) was modified for salinity conditions using 2009-2010 fieldexperiments data in southwest of Iran. Irrigation levels were: I1=1.0ETc+0.25ETc as normalleaching amount, I2=0.75I1 and I3=0.5I1...
متن کاملEffect of Organic and Inorganic Sources of Nitrogen on Maize Yield,N Uptake and Soil Fertility
mineral and organic N sources (farmyard manure) on maize yield, N uptake and soil fertility was assisted in the field experiment carriedout on silty clay loam soil at new developmental farm of the university of agriculture, Peshawar Pakistanduring 2014. Combined dose of N provided from all sources was applied @150 kg ha-1. There were four replications and 6 treatmentsi.e., (T1) control, (T2) 15...
