Growth and yield responses of ginger (Zingiber officinale Roscoe) as affected by shade and fertilizer applications

Abstract

Field experiments were conducted on a Vertisol to study the effect of shade and fertilizer applications in reducing lime‐induced iron chlorosis, thereby improving crop growth and yield of ginger. Plant height and tiller number were increased with shade treatment, while the severity of iron chlorosis was reduced. Ginger growth under 66% saran netting, inter‐cropped with ochro and inter‐cropped with corn and peas, significantly outyielded those plants intercropped with corn only and those with no shade. Fertilizer applications did not have any significant effect on yield in comparison to shade treatments.
