Plants of a pure line variety, G 24, of Cicer arietinum L. were grown in sand culture. After an initial dose of a complete nutrient solution, a nitrogen free nutrient solution was supplied to the sand at intervals and a standard rhizobial culture was added twice. The plants were treated with two concentrations of gibberellic acid (20 mg/l and 100 mg/l) through the rooting medium. At suitable intervals two pots from each treatment were sampled. Observations were made regarding the earliest initiation of nodulation, the number, weight and colour of nodules and the nitrogen content of different plant organs under various treatments. GA3 treatments enhanced nodule initiation. While 20 mg/l somewhat enhanced nodule number, weight and nitrogen content, 100 mg/l caused detrimental effects in the long run. Pod formation was delayed with GA3, the effect being much more pronounced with the higher concentration used. Pod and seed weights under 20 mg/l somewhat enhanced nodule number, weight and nitrogen content, 100 mg/l caused detrimental effects in the long run. Pod formation was delayed with GA3, the effect being much more pronounced with the higher concentration used. Pod and seed weights under 20 mg/l GA3 were almost comparable to the control, but 100 mg/l proved very deleterious. [ABSTRACT FROM AUTHOR]
