Influence of integrated phosphorus management on the growth, yield and quality of lentil (Lens culinaris L. Medik.)

A field experiment was carried out at the College of Agriculture, CAU, Imphal, Manipur during the rabi season of 2019-2020. The experiment was laid out in Randomized Block Design with three replications. There were nine treatments which consisted of different sole and combined application of phosphorus, organic manure and Biophos. The result indicated that application of 75% RDP + FYM @ 5 t/ha + Biophos @ 20 ml/kg seed (T4) recorded significantly higher growth parameters over all the other treatments in terms of plant height (28.17 cm), number of branches per plant (8.23), fresh and dry weight of plant (14.60 g and 6.26 g) and also the yield attributes such as number of pods per plant (164.30), number of seeds per pod (2.57) besides higher seed and stover yield (15.50 and 19.03 q/ha) as well as crude protein content (23.28%) and crude protein yield (367.83 kg/ha) of the crop. The treatment T4 was closely followed by T5 (75% RDP + Vermicompost @ 2 t/ha + Biophos @ 20 ml/kg seed) in respect of seed yield and crude protein content.
