Description This study investigated the haulms from 860 breeding lines and cultivars of groundnut (Arachis hypogaea) considering three prerequisites: (1) livestock-nutritionally important genotypic variation in haulm value (quantity and quality); (2) laboratory infrastructure that can predict fodder quality in a large number of plant entries; and (3) no serious trade-off between pod and haulm traits. Haulms were analysed by a combination of conventional laboratory techniques and Near Infrared Spectroscopy (NIRS). From 860 haulm samples, 180 representative samples were selected based on their NIRS spectra for conventional analyses of haulm nitrogen content by Kjeldahl method and haulm in vitro organic matter digestibility (OMD) and metabolizable energy content. Results showed that there was very good agreement between NIRS predicted and measured values. The R2 for the relationships were well above 0.90, which is considered excellent particularly for biological methods like determination of in vitro OMD and metabolizable energy content assessed on the basis of inoculation of substrate with rumen microorganism. Highly significant differences amongst genotypes were found for nitrogen content, in vitro OMD and metabolizable energy content of the haulms. It is encouraging to note that haulm fodder quality traits and pod and haulm yields were not inversely related. The relationships showed that high pod yield and superior haulm quality and quantity are compatible traits.
