  Seed yield in green gram was increased progressively with phosphorus application up to 75 kg P2O5 ha–1. The application of P2O5 more than 75 kg ha–1 depressed the yield and yield components. Maximum increase in seed yield, recorded at 75 kg P2O5 ha–1 was about 92% of control. Higher seed yield with phosphorus application was related to the higher number of pod bearing branches, number of pods per plant, number of seeds per pod and 1000-grain weight. Protein contents were also influenced significantly by phosphorus application, being maximum (27.01%) at phosphorus level of 75 kg ha–1. Phosphorus application of 75 kg ha–1 seems to be the optimum level for harvesting higher yield in green gram.

  Culture responses of 9 lentil explants were compared in various media having different ingredients. The most promising were the scrapped axillary portions of basal nodes for enhanced regeneration. The optimum size of the explant was also determined. The callogenesis response varied with the explant and ranged between 0.3-0.5 cm.
Among the sugars tested, sucrose was the best for callussing. Auxin 2,4-D induced callussing but cytokinin enhanced formationof shoot primordia in explants. Both BA and K promoted multiple shoot formation but K and GA gave more shoot buds. Cytokinins with auxins gave callusing. Callus was also induced in explants when grown in K (10 mg L–1) + GA (1 mg L–1) containing medium in the dark. When callus was shifted to light it started regeneration as green dots. The addition of seed extract to K and GA medium considerably enhanced regenerations.

  In vitro growth responses of various lentil genotypes varied. The best callussing response was noticed in variety ILL-4605. The genotype AARI-L-89503 had a tendency for embryogenesis. The genotype AARI-L-86642 had the best rooting ability. This genotype also showed in vitro flowering response. Masoor-85 and Pant-L-406 had moderate morphogenic responses, Meristem multiplication, shoot development, shoot bud formation from callus and adventitious rooting from shoot cuttings was obtained under appropriate growth regulators combinations.
