Growth Efficiency and Yield of Pigeonpea (Cajanus cajan L.) as Affected by Foliar Application of Mineral Nutrients
Journal Title: Journal of Plant Science and Research - Year 2015, Vol 2, Issue 2
Abstract
The study was conducted to determine the effect of foliar application of mineral nutrients on growth attributes of two pigeonpea varieties (PAU 881 and AL 201) for two successive seasons (2012-2013). Both the varieties showed identical pattern of results for plant height, number of branches, leaf area, leaf area index (LAI), specific leaf weight (SLW), crop growth rate (CGR) and relative growth rate (RGR). All the treatments of mineral nutrients (1mM CaCl2, 2mM CaCl2, 0.5% KNO3, 1% KNO3, 0.1% MgCl2, 0.2% MgCl2, 1% urea and 2% urea) had positive effect on growth attributes. Amongst all the treatments, 2% urea application caused maximum increase in growth attributes viz., plant height, number of branches, leaf area, LAI, SLW, CGR and RGR. These growth attributes showed significant positive correlation with yield. Thus, the application of mineral nutrients improved yield of pigeonpea varieties through enhancement of various growth attributes.
