Effect of planting geometry, nitrogen levels and zinc application on growth and yield of hybrid maize (Zea mays L.)
Heisnam Sobhana Devi and Dr. Gautam Ghosh
A field experiment was conducted during (kharif
) season of 2016 at the Crop Research Farm, Department of Agronomy, SHUATS, Allahabad in Randomized Block Design with three replications and twelve treatments entitled â€œTo study the effect of planting geometry, nitrogen levels and zinc application on growth and yield of Hybrid Maize (Zea mays
L.)â€. This experiment was conducted for comparing the performance of hybrid maize variety â€œMM2255â€. It consisted of two planting geometry (60Ã—15 cm and 45Ã—20 cm), three levels of nitrogen (150,120 and 90 kg ha-1 ) and two levels of zinc (7.5 and 15.0 kgha-1). It was found that in T2 (60 Ã— 15 cm + 150 kg N ha-1 + 15 kg Zn ha-1) highest plant height (200.47 cm), number of leaves per plant (14.27), dry weight (48.53 g). It also gave highest grain yield (5.70 t ha-1), and stover yield (14.76 t ha-1).The same treatment also gave highest B:C ratio(2.49) and net return of Rs 50018.56 ha-1 compared with the other treatments. This indicates that 60Ã—15 cm spacing with nitrogen level of 150 kg ha-1and zinc 15 kg ha-1is suitable to get higher maize yield, compared to other treatments.
