The uptake of 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine (atrazine) was studied in sudangrass [Sorghum sudanense(Piper) Stapf, var. Piper], grain sorghum [Sorghum bicolor(L.) Moench], and corn (Zea maysL.) to find whether differences in atrazine uptake exist among these species. The uptake of atrazine followed closely the growth patterns of corn, sorghum, and sudangrass during the first 5 weeks of growth. Concentration of14C from ring-labeled14C-atrazine in the soil reached a peak in corn, sorghum, and sudangrass plants after 2 weeks of growth and then declined. The14C concentrations were two to three times greater in sorghum and sudangrass than in corn throughout the 5-week period. Atrazine uptake per gram of plant growth by these crops was directly proportional to the concentration of atrazine in the soil and the proportionality factors were in the order: sudangrass < sorghum ≫ corn. Total uptake and the total growth were in order: corn ≫ sorghum = sudangrass. In a study where relative humidity was a variable, the amount of atrazine absorbed per ml of water was inversely related to total water usage.

The early growth of six cacao varieties important in the breeding program of the Cocoa Research Institute was investigated in sand cultures supplied with optimum and deficient levels of plant nutrients. The varieties tested were the Amazon selections Nanay (Ny) and Parinari (Pa), West African Amelonado (A), and their hybrids, NyA, PaA, and NyPa. Varieties Ny, NyA, and NyPa had similar growth patterns and were the fastest growing; varieties PaA and Pa were similar and the next best; and A was the slowest growing. In the control solutions variety Pa was larger than variety A, but in all deficient nutrient treatments except the calcium-deficient one, the two varieties grew to equal size.Nutrient levels in the leaves did not vary greatly between varieties, and apparently were not correlated with plant growth. The larger, more vigorous varieties had a higher percentage of small lateral absorbing roots than did the less vigorous varieties.The Amazon varieties Ny and Pa grew significantly less in the potassium-deficient nutrient solution than did the Amelonado variety A when compared with their controls. In addition, the symptoms of potassium deficiency exhibited by the Amazon varieties were more severe than those of the Amelonado variety.
