Agronomic and Photosynthetic Characteristics of Different Maize Hybrids in Response to Water Deficit Stress at Different Phenological Stages

The aim of present study was to evaluate the effects of drought stress on net photosynthesis rate (Pn), stomatal resistance, water use efficiency (WUE) and biomass (BM) of six maize (Zea mays L.) hybrids. Drought stress applied by withholding water supply at 4-5 leaf stage (S1, vegetative stage), anthesis (S2, reproductive stage), and dual stress condition (S3, combination of vegetative and rep...

Assessment Maize Hybrids Response to Biological and Chemical Nitrogen Fertilizers

This research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. To this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. Main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

The Response of Morphology, Yield and Yield Components of Spring Safflower Genotypes to Different Sowing Dates

In order to study the response of morphology, yield and yield components of spring safflower (Carthamus tinctorious L.) cultivars to different sowing dates, an experiment was carried out using a split-plot design on the basis of a randomized complete block design with four replications, in Agricultural Sciences and Natural Resources University of Khouzestan, south-west of Iran at 2016-2017. Exp...

CERES–Maize Model for Determining the Optimum Planting Dates of Early Maturing Maize Varieties in Northern Nigeria

Field trials were carried out in the Sudan Savannah of Nigeria to assess the usefulness of CERES-maize crop model as a decision support tool for optimizing maize production through manipulation of plant dates. The calibration experiments comprised of 20 maize varieties planted during the dry and rainy seasons of 2014 and 2015 at Bayero University Kano and Audu Bako College of Agriculture Dambat...

In situ Rumen Degradation Characteristics of Maize, Sorghum and Sorghum-Sudan Grass Hybrids Silages as Affected by Stage of Maturity

This research was conducted to investigate in situ degradation characteristics of maize, sorghum and sorghum-Sudan grass hybrids. whole plant of maize (TTM-815, DK-711), sorghum (SS-506, FS-5) and sorghum × Sudan grass hybrids (P-988, Grazer N2) were grown under semi-arid conditions and harvested at different maturity stages (mid-flowering (MF), milk-line (ML) and hard-dough (HD)) and ensiled. ...
