Crop photosynthesis, respiration and dry matter production of maize.

CROP ECOLOGY, PRODUCTION & MANAGEMENT Carbon Dioxide and Temperature Effects on Forage Dry Matter Production

sphere represents less change in CO2 concentrations at the RuBisCO binding sites for C4, resulting in a smaller Atmospheric CO2 and temperature may significantly modify plant response for the C4 compared with the C3 plant. High production. Grasslands occupy in excess of 25% of the Earth’s land area, but grassland species have received limited attention from retemperature also generally increase...

Increasing crop production through more controlled photosynthesis.

Effect of Different Levels of Nitrogen and Planting Patterns on Dry Matter Production and Growth Physiological Indices in Intercropping Maize and Sunflower

This research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. To do this a split plot experiment carried out based randomized complete block design with three replications in research field of Shushtar Islamic Azad University. The main plot included three level...

Predicting dry matter production of cauli ̄ower (Brassica oleracea L. botrytis) under unstressed conditions Part II. Comparison of light use ef®ciency and photosynthesis±respiration based modules

Six different modules for dry matter production of cauli ̄ower were parameterised and evaluated using a database of 22 cauli ̄ower crops originating from 15 independent ®eld experiments. The evaluation included a light use ef®ciency, LUE, based module assuming LUE to be constant, an LUE based module assuming a linear decrease of LUE with increasing daily photosynthetically active radiation sum, I...

Maize dry matter production and macronutrient extraction model as a new approach for fertilizer rate estimation.

Decision support for nutrient application remains an enigma if based on soil nutrient analysis. If the crop could be used as an auxiliary indicator, the plant nutrient status during different growth stages could complement the soil test, improving the fertilizer recommendation. Nutrient absorption and partitioning in the plant are here studied and described with mathematical models. The objecti...
