Response of turmeric (Curcuma longa L.) to micronutrient fertilizer mixtures applied at various levels and methods on the growth, yield and quality of rhizomes
Two field experiments were carried out with turmeric variety BSR 2 on sandy loam and sandy clay soils to assess the effect of newly developed multi-micronutrient mixtures on the growth, yield and uptake of micronutrients. There were fifteen treatment combinations comprising three different grades of newly developed turmeric mixtures which were applied at two levels (15 and 30 kg ha-1
) as fully at basal and as split applied equally at basal and on 90 days after planting. The mean data of both the experiments revealed that, split application of micronutrient mixture grade II @ 15 kg ha-1
equally at basal and 90 days after planting significantly increased the rhizome yield by 37.6 to 40.2 per cent over recommended NPK without micronutrients and showed 15.5 to 16.9 % increase in rhizome yield over recommended micronutrients application of 50 kg ZnSO4
+100 kg FeSO4
. The same treatment increased the growth and yield attributes of turmeric crop with better B: C ratio of 2.88. Though it was comparable with the split application of 30 kg grade III micronutrient mixture, it was comparatively economical and the yield increase was also higher hence can be recommended to turmeric grown on the soils having multi-nutrient deficiencies.
