Effect of split nitrogen application on growth parameters of maize

Abstract

A field experiment was designed to study the Effect of split nitrogen application on growth parameters of maize on research field of agricultural development trust, Baramati for two consecutive years during rainy season in 2017and 2018. An experiment was laid out in randomized complete block design with four replications. Four splits application of recommended dose of N were applied as 50% N at basal and 50% N at knee high stage (T1), 50% N at basal, 25% N 30 days after sowing and 25% N at tasseling stage (T2), 50% N at basal and remaining nitrogen as per Leaf Colour Chart (T3) and 30% N at basal, 30% N at 30 days after sowing and 30% N at tasseling stage (T4). Results showed that all studied parameters were significantly affected by application time of nitrogen. Experimental results exhibited that application of 50% N at basal and remaining nitrogen as per Leaf Colour Chart (LCC) has produced maximum plant height, number of leaves per plant and cob length. Results of these studies revealed that, application of N fertilizers based on leaf colour chart, would be more economical to minimize N losses from the soil and efficient use of N at critical growth and development stages of maize.
