Recent progress in cassava agronomy research in China
The paper discusses the research progress mainly for the period of 1990-1993. There are three institutions, SCATC, UCRI and GSCRI, which are systematically working on cassava breeding in China. Since the principal constraint to cassava varietal improvement is the lack of genetic variability, the ...
Cassava is an important root crop in Vietnam, and after rice and maize it is the major source of calories for human consumption and animal feed. Recently, cassava research has been supported by the national Root and Tuber Crops Resarch Program and by CIAT. Cassava agronomy research has produced t...

The report covers varietal improvement for the period 1990-1993. Not much progress was made in the 1990/91 season due to the occurence of a super typhoon that damaged standing field trials. In recent years, however, progress in selection was made in terms of high yield and dry matter content and ...

In Leyte, the long-term fertility trial under coconut showed significant responses to fertilizers after the second cropping cycle. Highest yields were obtained in treatments with 90 kg/ha of P O and 60 kg/ha of N and K O, while lowest yields were obtained in treatments without P application. In a...

A total of four sets of seeds (totalling 5526 seeds) were recieved from CIAT during the period 1990-1993. One set (comprising 1100 hybrid seeds) originated from the Thai-CIAT program in Rayong. Evaluation and selection of seedling clones has progressed satisfactorily, and culminated in the releas...

Cassava (Manihot esculenta Crantz.) in Indonesia can be considered as a controversial crop. This crop has a tremendous yield potential of almost 100 t of fresh roots/ha, but official data show that its actual productivity is only 10-20% of its biological potential. It is considered to have multip...

Cassava is planted each year in about 120,000 hectares of agricultural land in the Philippines, producing about 1.8 million tonnes of cassava roots. Principal products of the processing industry are food, dried chips and starch. As a traded commodity, however, cassava contributes only about 2% to...
Cassava (Manihot esculenta Crantz.) is cultivated in India in about thirteen states (out of 32 states and union territories) with major production in the South Indian states of Kerala (142,000 ha) and Tamil Nadu (65,700 ha). It is now a major industrial crop in Tamil Nadu and is also gaining impo...
