Abstract:
The field study conducted at College of Agriculture, Rajendranagar, Hyderabad on the response of Lucerne to irrigation scheduling, phosphorus and boron application indicated that the dry matter content and the uptake of N, P, K and B by Lucerne fodder and seed were higher with irrigation at 1.25 IW/CPE ratio. Phosphorus application @ either 80 or 120 kg P₂O₅ ha^-1 registered higher dry matter content, nitrogen and potassium uptake by fodder. On the other hand, highest level of phosphorus @ 120 kg P₂O₅ ha^-1 alone registered highest uptake of phosphorus and boron by fodder and seed. Application of boron @ 4 kg ha^-1 has resulted in highest dry matter content and nutrient uptake by Lucerne fodder and seed. On the other hand, soil available nitrogen was higher when irrigations were scheduled at 0.75 IW/CPE ratio with phosphorus and boron fertilization @ 120 and 4 kg ha^-1.
