Abstract
In field trials at Junagadh, India during the dry and wet seasons of 1985, 5 erect (Spanish bunch) and 3 Virginia runner (spreading) groundnut cultivars were evaluated for chlorophyll content, DM production, growth rate, nodule weight, N uptake, pod number and pod and haulm yields. Chlorophyll content peaked soon after emergence and was lowest at 4 weeks after emergence due to low N levels. Nodules developed 3 weeks after emergence and started to fix N and so increased chlorophyll content again. Chlorophyll content was higher in runner (cv. Robut 33-1, Punjab 1, GAUG 10) than in erect cultivars (GAUG 1, Kisan, TMV 2, JL 24, GG 2) and the runners accumulated more N and fixed more N. The Virginia runner cultivars had a higher pod number and yield than the erect types due to more DM and N accumulation and higher crop growth rate. The runner types also had a larger leaf area and higher percentage of N in their leaves throughout the season. Pod yield and DM production were greater in the dry season than in the wet season due to the longer duration of the crop.
