IMPACT OF NITROGEN AND PHOSPHORUS ON SEED YIELD OF CHICKPEA

Abstract

Performance of six brown chickpea (Cicer arietinum L.) genotypes viz. 90261, 93127, 97086, 98004, 98154 and Bittal-98 was tested under four NP levels (0-0, 1230, 24-60, 30-90 kg/ha) at Agronomic Research Institute, AARI, Faisalabad, Pakistan during 2006-07 and 2007-08. Fertilizer levels had a significant but differential effect on seed yield of chickpea genotypes. Fertilizer @ 24-60 kg NP per hectare gave better results during both the years. There was a linear increase in yield of all genotypes from 0-0 to 24-60 kg NP level. The differences among varietal means were non-significant during first year but significant during second year. However, on the basis of average of two years, genotype 98004 expressed comparatively more plant height (90.23 cm) and pods per plant (77.58), whereas, chickpea genotype 97086 produced higher biological (7658 kg/ha) and economic yields (2222 kg/ha). Genotype 93127 excelled in 1000- grain weight (285.54 g).
