Identification of operative dose of NPK on yield enhancement of desi and kabuli chickpea (Cicer arietinum L.) in diverse milieu

摘要

The effect of fertilizer on yield and yield related traits studied in two consecutive years at two different locations. Three different doses of fertilizer (NPK) applied at the rate of 9:23:0, 18:46:12 and 27:69:25 respectively on sixteen chickpea, genotypes (Desi and Kabuli advance lines and commercial varieties). Data recorded for days to 50% flowering, plant height, primary and secondary branches, pods per plant, 100-grain weight and grain yield (kg/ha). In Desi chickpea highest grain yield (kg/ha) in both years was produced by advance line D-12026 and in Kabuli advance line K-70005 at Faisalabad location. Grain yield kg/ha had significant positive correlation with all the considered parameters except days to 50% flowering and days to 50% maturity. The treatment comparison manifested that fertilizer doses 9:23:0 enhanced grain yield. The high dose of fertilizer is not recommendable. The grain yield of Desi and Kabuli chickpea at two locations Pulses Research Institute (PRI) Faisalabad and GBRSS (Gram Breeding Research Sub Station) Kallurkot had significant variation. The grain yield (kg ha ?1 ) was significant high in research area of PRI, Faisalabad in both years. The NPK 9:23:0 found operative dose of fertilizer for chickpea.
