Effect of Potassium and Zinc Deficiencies on Micronutrients Uptake of Gerbera Under Polyhouse Condition

The present investigation was carried out under polyhouse condition at the Hi-Tech Floriculture and Vegetable Project, College of Agriculture, Pune-5 during November-2011 to December-2012. The results of the experiment revealed that Iron uptake increased with days due to all nutrients treatments. Iron uptake increased with days slowly due to K deficiency treatments, while Iron uptake increased with day's upto 130 DAP but significantly decreased afterwards due to Zn deficiency treatments. Manganese uptake increased with days due to all nutrients treatments. Manganese uptake increased with day's upto 130 DAP but significantly decreased afterwards due to K and Zn deficiency treatments. Copper uptake increased with days due to all nutrients treatments. Copper uptake increased with days slowly due to K and Zn deficiency treatments. Zinc uptake increased with days due to all nutrients treatments. Zinc uptake increased with day's upto 130 DAP but significantly decreased afterwards due to K deficiency treatments, while Zinc uptake significantly decreased with day's due to Zinc deficiency treatments.
