Abstract:
A field experiment was conducted during kharif season of 2020 at Durtlang, Aizawl, Mizoram under the surveillance of Krishi Vigyan Kendra, CAU, Selesih,Aizawl, Mizoram, to study the growth and yield of maize (Zea mays L.) as influenced by varietal response and nitrogen levels. The experiment was compromised of Randomized Block Design with three replications and nine treatments. It consists of three varieties (Mimpui, Mimban and Puakzo) at three nitrogen levels (80,100 and 120 kg/ha). It was observed that T₅ (Mimban + 120 kg N haˉ¹) gave highest plant height (238.07). However, T₇ (Mimpui + 120 kg N haˉ¹) gave the highest dry weight (225.20g), number of grains rowˉ¹ (31.77), test weight (271.70g), grain yield (8.84t/ha) and stover yield (21.10 t/ha). It also gave highest net return of 104924.8, B:C ratio (4.29) as compared to the other treatments.
