This paper examines the performance of the Indian seed system in the context of high volume, low value seed, using the case studies of potato and groundnut. In theory, public sector should be able to address seed needs of farmers growing these crops. However, the ability of the public sector is constrained by a number of institutional and technical factors, and farmers largely depend upon traditional sources of seed. The traditional sources meet more than two-thirds of the total seed demand , and the rest is met by the formal seed system, mainly public seed agencies. Most of the farmers buy fresh seed for quality reasons, and only 12-15 percent farmers purchase seed to change variety. In potato, technological innovation provided options to enhance... |

ABSTRACT: Intensification of drought in Mediterranean–type climates has limited seedling establishment. The knowledge of the ecology of selected species and its intraspecific variation to water stress at the seedling stage should be considered in order to overcome limitations. We investigated variations in growth, survival, and leaf–level physiology in four provenances of the endemic Cryptocarya alba (Mol.) during water stress and after re–watering. Seedlings were cultured in the nursery during 23 months and then subjected to two watering treatments based on soil water content (well–watered and water restriction, 0.38 and 0.17 cm3 cm−3, respectively) for 45 days. At the end of the watering treatments, seedling growth, above– and belowground biomass,... |
