Response of Ginger to Zinc and Boron Fertilization

N.K. Halder, N.C. Shill, M.A. Siddiky, R. Gomes and J. Sarkar

A field study was conducted at Brown Hill Soils (Eutrochrepts) of South Eastern Hilly region at Hill Tracts Agricultural Research Station, Ramgarh, Khagrachari during the Kharif seasons of 2004-2005 and 2005-2006, respectively. The objective was to evaluate the response of ginger (cv. local) to B and Zn fertilization and to find out the optimum dose of Zn and B for maximizing yield of ginger in Hilly Region. Four levels of B (0.1, 2 and 3 kg ha-1) and Zn (0, 1.5, 3.0 and 4.5 kg ha-1) along with combined blanket dose of N180 P50 K120 S20 and CD5 t ha-1 were taken in the experiment to study. It is evident from studied data revealed that Zn either in single or in combination with B made significant effect on ginger production in micronutrient deficient soils. However boron produced 46.72% higher yield in first year and 89.92% higher yield in second year over boron control (Bo) whole calculated 23.72 and 52.26% higher yield than that of Zinc in two consecutive years. The integrated effect of B and Zn was found to be highly significant and markedly influenced the rhizome yields and other yield attributes of ginger. The boron (3 kg ha-1) and zinc (4.5 kg ha-1) individually produced rhizome yield 23.5 and 25.8 t h-1 and 20.4 and 22.3 t ha-1 in three consecutive years of 2004-2005 and 2005-2006, respectively. However, integration of Zn and B at the maximum level (B3.0 Mo4.5 kg ha-1) significantly produced the highest ginger yield (25.5 and 26.8 t ha-1) and 125 and 143% yield increase over Boron-Zinc control (Bo Zno) in two successive years of study. Similarly, the highest net economic return Tk.7, 52.030 and Tk. 804000 and the highest marginal rate of return (MRR) 484 and 548%, respectively were obtained with the application of B at the rate of 3 kg ha-1 and Zn at the rate of 4.5 kg ha-1 which was found to be economically profitable for ginger production in South-Eastern Hilly region.
