Abstract

A field experiment was conducted during the Kharif season in 2017 to evaluate the effect of the mode of micronutrient application along with insecticides on the growth and yield of pigeonpea (Cajanus cajan L.) in sandy loam soil. Eight treatments consisting of micronutrients and insecticides (Urea, B, Zn, Indoxacarb, and one systemic insecticide), namely T1 [RDF i.e., Control (NPKS)], T2 (T1 + 2% urea spray at 50% flowering), T3 (T1 + 0.5% B spray at 50% flowering), T4 (T1 + 0.5% Zn spray at 50% flowering), T5 (T1 + 2% urea + 0.5% B + 0.5% Zn spray at 50% flowering), T6 (T1 + multi-micronutrient spray @ 2ml/liter of water), T7 (T1 + Indoxacarb at flowering + one systemic insecticide 15 days after the first spray), T8 (T6 + Indoxacarb at flowering + one systemic insecticide 15 days after the first spray), were tested in a Randomized Block Design (RBD) with three replications. NPKS was commonly applied in all the plots. The experimental results revealed that growth attributes (plant height, number of primary branches per plant), yield attributing traits (pods per plant, grains per pod, test weight), and yield in pigeonpea differed significantly among the different treatments and were maximized with T8. Therefore, the study suggests that considering the combined application of different micronutrients and insecticides can be beneficial for optimizing the growth and yield of pigeonpea.

Conclusion

From the present investigation, it is concluded that the application of micronutrient sprays and insecticides can significantly improve the yield of the crop. The experiment evaluated the effect of different treatments on the growth and yield of a pigeonpea. The treatments included the use of fertilizers, micronutrient sprays, and insecticides (Table 1). The results show that the application of T2, T5, T6, T7, and T8 increased the yield of the crop compared to the control (T1).
