Abstract
In seeking a solution to the problem of 'blindnuts'
often reported in parts of the Sudan ecological zone of
Nigeria, investigations were carried out for two seasons
at Ladanawa (12°32'N; 07°38'E) backed by one season of
observation at Samaru (Northern Guinea savanna, 11 ll'N;
07°38'E) to observe the effects of moisture and gypsum on
groundnut development and fill. Despite difficulties of
management experienced in the conduct of the trials treatment
effects were generally consistant between seasons and
locations.
The application of supplementary irrigation generally
increased the amount of vegetative growth as measured by
height, foliage cover and number of vegetative branches.
It was evident that the most important factor which adversely
affected groundnut pod-fill and yield was inadeguate
moisture availability particularly at the time of peg formation
and pod development. The use of gypsum without first
nsuring the supply of adequate moisture did not help much
in alleviating the problem of groundnut pod-fill.
