Abstract
The influence of plant hormones and level of phosphorus (i.e. 0, 40 and 60 kg P2O5 ha-1) on growth and yield of field pea (Pisum sativum L.) was conducted at Campus for Research and Advanced Studies Dhablan of the G.S.S.D.G.S. Khalsa College, Patiala, Punjab during Rabi-2017-2018. The experiment laid out in factorial randomized block design with 3 replications, consisting of 12 treatment combination. The soil of experimental field was clay in texture with pH 7.3 and contained organic carbon 0.52, available nitrogen 262 kg ha-1, available P2O5 22.6 kg ha-1, available K2O 129kg ha-1. Application of 60 kg phosphorus ha-1 recorded significantly higher growth characters viz. plant height, number of leaves, number of branches, fresh weight and dry weight and yield (grain and straw yield) than lower levels of 40, 0 kg phosphorus ha-1. Significantly higher growth and yield of field pea was recorded with GA3 + IAA +IBA (50ppm + 50ppm + 50ppm) as compared to others. The maximum B: C ratio was recorded with application of 60 kg phosphorus ha-1 and GA3 + IAA +IBA (50ppm + 50ppm + 50ppm). From the result, it was concluded that the maximum yield of the field pea could be achieved by application of P2O5 @ 60 kg ha-1 and GA3 + IAA +IBA (50ppm + 50ppm + 50ppm).
