Dry Matter, Nitrogen, Phosphorus, and Potassium Accumulation Rates by Corn on Norfolk Loamy Sand1
Agronomy Journal, 1987AbstractThe maximum amount and rate of nutrient accumulation by irrigated corn (Zea mays L.) must be known so that farmers do not waste money or pollute water resources by applying excessive amounts of fertilizer. Aerial whole plant samples were therefore collected from irrigated field experiments conducted on Norfolk (Typic Paleudults) loamy sand in ...

Abstract Field experiments conducted in 2007/08 and 2008/09 at the Changwu Agricultural Research Station on the Loess Plateau of China comprised three seeding rates (SR1: 225 seeds m −2 , SR2: 280 seeds m −2 , and SR3: 340 seeds m −2 ) and two root pruning treatments (W: root pruning in the over-wintering period and S: root pruning at the spring ...

SummaryWe investigated the effects of light intensity on various photosynthetic characteristics on a whole-plant (WP) basis, focussing on three developmental stages from leafing (when young leaves unfolded) to flowering in the Oriental hybrid lily ‘Siberia’.

Results of an experiment over five solution P concentrations ( 1 , 2, 4, 8, 16 8M P) and five harvests were used in a response surface approach to determine the size and incorporation rates of major plant P pools in white clover (Trifolium repens cv. Ladino) and stylo (Stylosanthes hamata cv.

A 3-year experiment (September 1999–August 2002) was conducted in south-western Victoria to determine the impact of spring grazing on pasture accumulation rates, dry matter (DM) consumed yield (estimate of DM yield), and pasture nutritive characteristics [metabolisable energy (ME), crude protein (CP), neutral detergent fibre (NDF), and water-soluble ...

This study tested the hypothesis that genetic differences for sink activity, a component of sink strength, affect assimilate flux to seeds in soybean [Glycine max (L.) Merr.]. Dry matter accumulation rate per unit seedcoat area (SDMAR) was selected to investigate sink activity.

A field trial with flue-cured tobacco conducted on a red paddy soil showed that the dry matter accumulation in the tobacco reached a peak in 50-60 days after transplanting, but was lower within 30 days or over 80 days after transplanting. The dry matter accumulation was increased with increasing K application rate and its supplemental proportion. The K
