Interaction effect of different levels of potassium and varieties on performance of chickpea

Abstract

Judicious use of fertilizers particularly potassium is essential for obtaining the maximum yield of chickpea. So, the present study was carried out to assess the interaction effect of different levels of potassium and varieties on performance of chickpea. The present investigation consisted four levels potassium (K1-0, K2-30, K3- 60 & K4-90 kg potash ha-1) and three varieties (V1-Udai, V2 - Awarodhi and V3 - KWR-108) observation recorded on growth, yield attributes and yield. The present investigation revealed that the maximum fresh weight and dry weight of plant at flowering and maturity stage, number of seeds per plant, grain weight per plant, grain and straw yield were recorded in K4 treatment (90 kg potassium ha-1) and variety V3 (KWR-108). However, maximum number of primary and secondary branches per plant, fresh weight of plant, dry weight, number of pods per plant, number of seeds per plant, weight of pod per plant, biological, grain and straw yield were recorded unfertilized plot K1 (0 kg potassium ha-1) and variety V1 (Udai). Thus, for obtaining maximum yield and profit from chickpea, KWR-108 variety should be grown with 90 kg potassium ha-1.
