Influence of Organic Amendments on Ginger (Zingiber officinale rosc.) Growth and Yield

The present investigation was conducted during the year 2020-22 at the Horticultural Research Station, Mondouri, BCKV, Nadia, West Bengal. The variety Gorubathan was selected for this study. The experiment was laid out in randomized block design. Raised beds of 3.0 m x 1.0 m and 15 cm in height were prepared. The main objective was to study the influence of organic amendments on growth, yield and economics of ginger. There were altogether five combinations of FYM and neem cake with six replications namely FYM@ 15t ha-1 + neem cake@ 1t ha-1(T1), FYM @15 t ha-1+ neem cake@ 2t ha-1 (T2), FYM@ 15 t ha-1 + neem cake@ 3 t ha-1(T3), FYM@ 23 (15+8) t ha-1 (T4) and FYM @ 15t ha-1 (Control). Application of FYM @15t ha-1 + neem cake@ 3 t ha-1, (e.g. T3) recorded maximum plant height of 39.68 cm, 65.33cm and79.58cm at 90,150 and 180 days after planting. At harvest T3 recorded maximum weight of 191.91g per clump, 3.63 primary fingers 4.22, secondary fingers, and highest projected yield (24.49t ha-1) respectively. Highest B: C ratio of 2.35 along with maximum net return of Rs 687341 ha-1 was recorded in the combination of FYM @15t ha-1 + neem cake@ 3 t ha-1, (T3).

Considering all the parameters it may be concluded that FYM@15t ha-1+neem cake@ 3tha-1 (T3) was the most effective organic treatment combination for obtaining maximum profit from ginger and may be recommended. In view of the world demand for organic food, the improvement of soil health, productivity and the availability of local resources, cultivation under organic farming can be encouraged.
