Nutritional studies of cassava have shown that in high-P acid laterite soils, there was no response to P application during four years of consecutive cropping. In low-P soil, even though cassava initially responded to 100 kg P2O5/ha, the response gradually declined. The optimum economic dose of P...

Progress in agronomy research in India
Annual growth of cassava production in the main cassava production areas during the last five years seems to have kept pace with the increase in population, while the harvested area of cassava increased only 0.6% annually. Of the total cassava produced, about 54% is used for human food, 28% for i...

During the last three years cassava production in the Philippines did not progress markedly, neither in area nor in volume. In terms of area, there was only an increase of 14,424 ha or 6.4%, while in terms of volume the increase was 112,177 metric tons or 5.7%. One of the reasons for this was the...

Research of the physiology section was centered on identifying the characters associated with high root yields and quality in cassava under stress conditions. Plant reaction to water stress was studied, specifically regarding growth and yields of var. M Mex 59 and M Col 22 with a period of artifi...
