Abstract

A field experiment was conducted at Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during rabi 2011-12 and 2012-13 to study the real time nitrogen management using leaf colour chart (LCC) in wheat (Triticum aestivum L.). Basal dose of 60 kg N/ha was applied in all the treatments. Top dressing of N in form of Urea either in one or two splits at LCC 3, 4 and 5 were compared with fixed time N application (60 kg N/ha at 25 DAS). Top dressing of 60 kg N/ha in two equal splits at LCC 4 and 5 significantly improved growth and yield attributes viz., plant height, number of effective tillers per m row length, spike length and test weight along with higher grain and straw yields, grain protein content and economic returns over fixed time application of 60 kg N/ha at 25 DAS.

Key words: Wheat, Nitrogen, Leaf colour chart.
