Discussion Squire's paper drew on data from India, West Africa, and controlled environment conditions in the UK, and provided a review of the relationships be tween many of the important environmental variables, and pearl millet growth. The discussion centered around the usefulness and application of these data, on the simple model presented, and the general acceptance of the root growth data and its measurement. The overall opinion was that the model was flexible, but the speaker admitted that more good data were required, particularly in relation to roots. The importance of saturation deficit was not challenged, and the speaker agreed that traditional methods for the measurements of roots and soil-water such as potentiometers and the neutron probe were probably better than sophisticated tracer methods. Matlon's paper clearly showed that interpretation of experiment station data, generated utilizing many inputs not available to West African farmers, should be done cautiously. Similar caution should be observed when comparing data from the three climatic zones, the Sahel, the Sudanian, and the Northern Guinean Zones. The discussion centered around these two issues. The poor response of new cultivars compared to locals under both low- and higher-input conditions on farmers' fields was clearly disturbing to the audience, but the consensus, substantiated by the data presented, was that this is a problem, and ICRISAT should concentrate on solving it. There was some disagreement about the statement that very early-maturing cultivars will have no impact unless management practices change. There was general acceptance that the primary goal in the Sahel is to increase the responsiveness of new cultivars to improved management, but that in the other two zones, the goal is to improve yield stability. The group endorsed a comment that more emphasis should be put on soil and water management in West Africa. Fussell's paper provided potential solutions to the problems outlined in Matlon's paper. Little progress would be made in increasing grain yield unless fertilizer is used, particularly phosphate. This was accepted with the proviso that the importance of water and soil management should not be completely dismissed. Gautam's paper described the management practices to increase and stablize production in India. The discussion centered on matching plant populations to different environments, and the placement and timing of fertilizer applications. Bidinger's paper, which acknowledged that plants have no immunity to environmental stresses, presented a physiological approach to breeding for 'resistance' to such stresses. A stepwise approach, using data from Niger and India, was used to illustrate the approach. Poor crop establishment and inadequate grain filling were used as examples. The discussion centered on whether the approach was over simplified, and whether there was a danger in examining growth stages or stress periods separately. Bidinger argued that understanding each stage separately and clearly defining the problems in a particular climatic zone was necessary. It was agreed that stress incurred in the seedling stage, provided the seedling survived, could be advantageous to a plant subjected to stress in the later stages of development. 279
