LEAF AREA AND NET ASSIMILATION RATE AS DETERMINANTS OF CROP YIELD [PDF]

, 1966
The relation of agronomic practice to crop yield is discussed in terms of photosynthetic efficiency of the crops (as measured by Leaf Area and Net Assimilation rates). The importance of a study of these factors in certain tropical crops is indicated.

Net assimilation rate and relative nitrogen assimilation rate in relation to the dry matter production of alfalfa cultivars

Plant and Soil, 1981
Twelve alfalfa cultivars inoculated with an indigenous strain (RM9) ofRhizobium meliloti, were compared for their seedling morphological characters, and growth characters, including net assimilation rate (NAR), relative growth rate (RGR), leaf area ratio (LAR) and relative nitrogen assimilation rate (RN).

Net assimilation rate of wheat as affected by light intensity and temperature

Canadian Journal of Botany, 1969
The net assimilation rate of wheat, on a leaf area basis, declined with time under constant environmental conditions. With continuous illumination at temperatures of 20, 25, and 30 °C, the net assimilation rate increased linearly with increases in the light intensity over the range 200 to 5000 ft-c. The optimal temperature was 15 to 20 °C, and the net

Changes in Net Assimilation Rate and Leaf-area Ratio with Time in Dactyl is glomerata L.

Annals of Botany, 1971
Two natural populations of Dactylis glomerata, one from Norway and the other from Portugal, were grown at four temperatures in a 16-h photoperiod. Seedlings were harvested at six equal intervals of 7 days at 5 and 10 °C, and 3-5 days at 20 and 30 °C.

Net assimilation rate of cotton in relation to spacing

The Journal of Agricultural Science, 1976
SummaryThe net assimilation rates (NAR) of three genotypes of cotton differing in their growth habit were studied under different spacings. The NARs of a very bushy type, G 67, and a comparatively less spreading type, IAN 560, were the same but that of a compact type, IAN 579, was twice as much when the leaf area index (LAI) was one.
