Nitrogen Use Efficiency in Tomato (Lycopersicon esculentum L.) and French Bean (Phaseolus vulgaris L.) as Influenced by Coating of Urea with Neem Oil and Graded Levels of Nitrogen

In a pot-culture study, 'Arka Shrestha' tomato and 'Arka Komal' French bean were raised on red sandy-loam to compare urea coated with neem oil (2% w/w, NOCU) and prilled urea (PU) applied at 60, 80 and 100% of recommended N dose. To facilitate direct measurement of N use paramete...
