Abstract
A field experiment was conducted during rabi season 2020-21 at the Crop Research Center of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) to evaluate the Effect of Zn and B application. Ten treatments comprising control, RDF, Zn and B in a different combination were tested in a randomized block design with three replications. The experimental results revealed that yield attributing traits viz. number of pods plant-1, number of grain plant-1, grain yield plant-1, test weight and biological yield, grain yield, straw yield and content and uptake of N, P, K, Zn, S, and B in lentil differed significantly among different treatments. Growth parameters were significantly better in the treatment T10 (RDF + Boron 2 kg ha-1 + Zinc 5 kg ha-1). The highest grain yield was recorded in T10 RDF + Boron 2 kg ha-1 + Zinc 5 kg ha-1 which were statistically at par with T8. It is concluded based on the study that the application of RDF + Boron 2 kg ha-1 + Zinc 5 kg ha-1 with Zn, and B (T10) gave best results (Grain yield increased by 26.7%, 25.7%, 21%, 22.9%, 17.2% and 59.1% over T1, T3, T4, T5, T6 and T1, respectively) and proved to be beneficial for rabi lentil followed by RDF + Boron 2 kg ha-1 + Zinc 5 kg ha-1 (T9). The balanced and combined use of Zn, and B along with N, P, K and S in lentil improved the yield attribute, yield, and total uptake of nutrients along with maintaining the soil fertility.
