Interaction Effect of Phosphorus and Boron on Yield Components, Productivity Parameters and Quality Traits of Lentil (Lens culinaris L.)

A field trial was conducted on sandy loam soil having low status of organic carbon and accessible nitrogen, medium in accessible phosphorous and high in accessible potassium at pot house of department of Soil Science and Agricultural Chemistry of C.S.A.U.A&T, Kanpur (campus) under Indo-Gangetic Plain zone of Uttar Pradesh, amid Rabi season of 2021-22. The experiment comprised of 16 treatment combinations in Factorial randomized block design with three replications. Lentil variety Lentil Shekhar 2 (KLB-303) was grown with the recommended agronomic practices. On the premise of the comes about exuded from the present investigation, it might be concluded that application of 60 kg P2O5 ha-1+ 2.5 kg Boron ha-1 significantly recorded maximum yield components viz. no. of pod plant -1 (71), Seed pod -1 (1.84) and Seed Index (3.23 g). Similarly, among the productivity parameters such as grain yield (15.67 q ha-1), straw yield (28.22 q ha-1), biological yield (43.89 q ha-1) and harvest index (35.70%) was also associated with the application of 60 kg P2O5 ha-1+ 2.5 kg Boron ha-1. Among the quality traits maximum protein content (22.40%) and protein yield (351.00 kg ha-1) was also associated with the application of 60 kg P2O5 ha-1+ 2.5 kg Boron ha-1. The present experiment clearly points out the significance of balanced use of Phosphorus and Boron nutrients in Lentil for improving the yield components, yield and quality of Lentil crop.
