Description
Effect of Mn, Al and Dolomit on growth of clove.The effect om Mn, Al, Dolomit on growth of clove were investigated at laing Experimental Garden of Solok Spice and Medicinal Crops Research Sub Institute. A randomized block design with seven replications was used. Treatments contained tho levels doses of Mn (0 and 250 ppm), two levels doses of Al (0 and 50 ppm), and two levels doses of Dolomit (0 and 1000 g). the results showed that the applications of 250 ppm Mn per year per plant and 50 ppm Al per year per plant resulted in abscised symptoms on height, number of leaves, and score of growth. The abscised symptoms can be eliminated by Dolomit application of 1000 g per tree per year. The toxic effect of Mn and Al could be neutralized by Dolomit in same way.
