Abstract

Chickpea ranks third among the world's pulse crops. it produces 7.4 million metric tonnes of dry seed from an area of about 10.0 million hectares (FAO, 1988). As the first pulse crop of Pakistan, Its importance as a daily protein food of people is immense. ~t was grown on an area of 979,000 hectares and produced 456,000 metric tonnes of dry seed during 1988 (Anonymous, 1989) Pakistan ranks second in the world in area and third in production. The crop is grown under three cropping systems: (i) rainfed system which constitutes 88 % of the total chickpea area, where it is grown as a pure or mixed with other crops, (ii) rice-based system constitutes 11 % of the total area and is grown on residual moisture, (iii) irrigated system which constitutes only 1 % of the total area. Eightyseven percent of the chickpea is grown on sandy to sandy loam soils and 13 % is grown on clay to clay loam soils (Anonymous, 1988). Major part of production is contributed by the rainfed system, prone to frequent fluctuations from year to year.
