A study on fenugreek growth found that using 20 kg of nitrogen and 40 kg of phosphorus per hectare resulted in taller plants and higher seed and straw yields. Adding Rhizobium and PSB bio-fertilizers to the seeds also increased plant height and boosted seed and straw yields. The best results were seen when both bio-fertilizers were used together. Harvest index was not affected by the levels of nitrogen, phosphorus, or bio-fertilizers.
