Impact of foliar applied nitrogen on the growth and yield of barley (Hordeum vulgare L.) at local climate condition at Sindh
Abstract
A field study was conducted at Students Farm, Sindh Agriculture University, Tandojam during Rabi, 2013-14 to investigate the growth and yield of barley under the influence of foliar spray of nitrogen. The local variety of barley was tested against seven treatments of foliar application of nitrogen viz. control, 1.0% nitrogen at tillering stage, 1.0% nitrogen at booting stage, 2.0% nitrogen at tillering stage, 2.0% nitrogen at booting stage, 1.0% nitrogen at tillering stage +1.0% nitrogen at booting stage and 2.0% nitrogen at tillering stage +2.0% nitrogen at booting stage. The analysis of variance showed that application of various treatments of foliar applied nitrogen exerted significant (P<0.05) positive effects on growth and yield parameters of barley as compared to control. The results suggested that foliar application of 2.0% nitrogen at tillering stage + 2.0% nitrogen at booting stage resulted in maximum plant height (66.7cm), tillers (490.7m-2), spike length (8.3cm), grains per spike (35.0), seed index:1000 seed weight (30.3g), biological yield (7116kg ha-1) and grain yield (3077kg ha-1). Hence, it is concluded from the results that foliar application of nitrogen at 1.0% nitrogen at tillering stage +1.0% nitrogen at booting stage along with recommended dose through soil proved best treatment for obtaining optimum yield (2972kg ha-1) of barley because it showed non-significant (p>0.05) statistical differences with highest numerical yield (3077kg ha-1) producing treatment 2.0% nitrogen at tillering stage +2.0% nitrogen at booting stage.
