69. Effect of starter nitrogen on yield and yield components of chickpea (Cicer arietinum L.) at Dokri, Larkana
Main Article Content
Abstract
Nitrogen (N) fixing capacity of legumes varies greatly among species and due to soil conditions. Poor soil conditions may cause yield reduction of chickpea as a result of limited biological N fixation. A field experiment was conducted to evaluate impact of starter N levels on growth and yield of chickpea. Study was planned with four levels of starter N (0, 15, 30 and 45 kg N ha-1) with three replications at Research Area, Agronomy Department, Rice Research Institute, Dokri during 2014-15 and 2015-16. The variety DG-92 was used in the experiment. Results show that plant height, number of pods per plant, seed index and seed yield were significantly improved with the various levels of starter N. The results of correlation coefficient in 2014-2015 and 2015-2016 years were positive and significant correlations of seed yield with majority traits.
