“…MOORBY (1968) found that after tuber initiation a two-to threefold increase in the assimilation of ^'^COj occurs and the proportion of assimilates exported from the leaf is doubled, most of this going to the tubers. MOLL (1980) reported minimum photosynthetic rates at the time of tuber initiation, a maximum during the period of linear bulking of the tubers, and then declining rates at the time when the crop reached 60-70 % of the maximum yield. DWELLE et al (1981a) found a similar pattern in field studies.…”

In field experiments conducted for 2 consecutive years at Shimla (31''06'N, 77°10'E at 2202 m above mean sea level with potato {Solarium tuberosum L.), weekly means of rainfall (P), potential evapotranspiration (PET), pan evaporation (PAN) and photosynthetically active radiation (PAR) were estimated during the crop season. It was evident that from April to end of June, the evaporative demand was more than the precipitation and that the crop suffered from water deficit from emergence to tuber initiation. Four different energy summation indices accumulated over important phenological stages of growth and energy-use efficiency in terms of biomass production at these stages were estimated for two seasons. Weekly cumulative biomass production showed a significant correlation with accumulated PET, PAN and PAR in the four genotypes tested in year 2.
