Evaluating chickpea varietal performance under different levels of phosphorus application

Chickpea, a vital legume crop, faces yield limitations due to factors like climatic conditions, nutrition deficiency in soil etc. Therefore, the knowledge of adoptive varieties to prevailing climatic conditions and enhancement yield by nutrient management is essential. The present investigation was carried out to assess the effect of varying levels of phosphorus on growth and yield of chickpea, at Agricultural Research Farm of SGRR University, Dehradun during Rabi season of 2022-23. The treatments of experiment comprise two chickpea varieties viz., PG-186 (V1) and Type 9 (V2) and five levels of phosphorus application i.e., 0, 15, 30, 45 and 60 kg P2O5/ha which were replicated thrice in factorial randomize design. The growth and yield parameters were recorded during different crop growth stages to get the response of treatments. The recorded data shows that the variety Type 9 perform better than variety PG-186 in most of the growth and yield attributing characters. Among the phosphorus doses the application of 45 kg P2O5/ha was perform best among all other treatments. The interaction effects of variety Type 9 with 45 kg P2O5/ha (V2T4) showed maximum growth and yield attributing characters over the other treatment combinations like plant height (46.66 cm), number of branches per plant (5.67), dry matter accumulation in plant (30.67 g), 1000 seeds weight (140.00 g) and seeds yield per hectare (14.30 q/ha). Based on experimental findings it can be concluded that variety Type 9 with application of 45 kg P2O5 /ha is best among all other treatments for higher yield of chickpea at Doon valley of Uttarakhand.
