| dc.description.abstract | A field experiment was conducted at the Horticulture Farm, Hajee
Mohammad Danesh Science and Technology University, Dinajpur during
November, 2006 to March, 2007 to evaluate the effects of Zinc and
Calcium on growth, yield components and yield of potato cv. Diamant.
There were four levels of Zinc, namely, 0, 3, 6, and 9 kg Zn/ha and
also four levels of Calcium, namely, 0, 15, 25 and 35 kg Ca/ha for this
study. The results of the experiment revealed that number of leaves,
fresh weight of haulm per hill and weight of tubers per hill, yield per
plot, yield per hectare, net return and cost benefit ratio were maximum at
6 kg Zn + 25 kg Ca/ha, while the minimum values were recorded from
control. Days to 80% emergence of plants were influenced by the
combined application of Zinc and Calcium. Increasing doses of Zinc
and Calcium resulted significant increase in growth and yield of tubers.
For individual application the highest yield of tubers 24.48 t/ha and
24.58 t/ha were obtained from 6 kg Zn/ha and 25 kg Ca/ha,
respectively. The maximum yield of tubers (30.56 t/ha), highest net
return (Tk.2,61,939.24 /ha) and cost benefit ratio (3.5) were observed in
combination of 6 kg Zn +25 kg Ca/ha. | en_US |
