Liming and foliar diagnosis on saccharine sorghum (Sorghum bicolor L. moench)

, 1985
The application effects of five levels of dolomitic limestone (0 - 1,25 - 2,50 - 5,00 and 10,00 kg/ha) were studied in a Typic Haporthox soil. Liming increased sweet sorghum stems ant the highest yield was obtained when the amount of calcium and magnesium, bases in saturation and soil pH value were, respectively, 2,93 meq/100 cm³ , 59% and 5,71. It was

Foliar diagnosis in sugar cane: VI - effect of rainfall on the foliar N, P and K of the plant cane

, 1982
By using data collected from the literature, it was possible to derive equations which correlate leaf composition with the rainfall in the 9 weeks (two months) before sampling. For each 200 mm of rain there was a variation in P contents from 0,016 to 0.034% (depending on the type of soil); in the case of K the variation was 0.071%.
