Most commercial Brachiaria species are adapted to low-fertility acid soils of the tropics. We describe, with examples, some of the attributes that enable them to adapt. These include the ability to (1) maintain root growth at the expense of shoot growth; (2) acquire and use both nitrate and ammon...

Over the past 25-30 years, cassava agronomy research in India has made tremendous progress. In the recent past there has been a steady increase in the cultivation of cassava in nontraditional areas, despite the fact that cereals form the major crop and staple food of the country. There has been a...

In Indonesia, annual growth rates for cassava production and yield from 1961 to 2000 were 0.81% and 1.35%, respectively. However, the harvested area decreased at an average annual rate of 0.61%. The average yield of about 12 tonnes of fresh roots/ha is much below the potential yield of 20 to 40 t...

In the past few years, the economy of Vietnam has developed very rapidly, and in agriculture, food production has been quite successful, especially that of rice. At the same time cassava production has changed from being a crop providing food for humans to being a cash crop. The planting of new c...

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...
