Tillage and NPK effect on growth and yield of spring maize in Islamabad, Pakistan

Tillage is a very important crop production practice which affect crop performance. An experiment was conducted during the spring crop season 2009 to compare the effect of three different tillage regimes i.e. deep, conventional and zero and four fertilizer levels viz., control 100-50-50, 150-75-75 a...

Description
Summary:Tillage is a very important crop production practice which affect crop performance. An experiment was conducted during the spring crop season 2009 to compare the effect of three different tillage regimes i.e. deep, conventional and zero and four fertilizer levels viz., control 100-50-50, 150-75-75 and 200-100-100 NPK kg per ha. The randomized complete block design was used with three replications. There was a significant difference in maize emergence percentage, plant height, grains per cob, 1000-grain weight and grain yield due to tillage practices and various fertilizer levels, between tillage practices. However, the NPK @ 200-100-100 kg per ha and deep tillage produced the highest emergence percentage, plant height, grains per cob, 1000-grain weight and grain yield followed by other fertilizer levels and conventional tillage. The zero tillage plots produced the low emergence percentage, plant height, grains per cob, 1000-grain weight and grain yield. Therefore, considering the environmental conditions, the deep tillage with recommended dose of NPK performed best and provided more vegetative growth and grain yield in maize. However, poor-resource farmers can use the medium level of NPK @ 150-75-75 kg per ha for getting an economical and successful maize crop.
