EFFECT OF PHOSPHATIC FERTILIZER, PHOSPHOBACTERIA AND SEED SIZE ON PLANT STAND, GROWTH AND YIELD OF SUMMER GROUNDNUT (ARACHIS-HYPOGAEA)

A field experiment was conducted during summer season of 1992 and 1993 to study the influence of phosphorus levels, phosphobacteria and seed size on plant stand, growth and yield of summer groundnut (Arachis hy pogaea L.). Pooled results indicated that levels of phosphorus did not exert their significant effect on growth characters, yield attributes and pod and haulm yields of groundnut. Significantly higher pod weigh t/plant, pod and haulm yields were observed where seeds were inoculate d with phosphobacteria. Large seed size was found significantly superi or to all other sizes for all the growth characters, yield attributes and pod and haulm yields of groundnut.
