Effects of multi-micronutrient mixture on growth, yield and quality of the summer pearl millet (Pennisetum glaucum L.)

A field experiment was conducted on loamy sand soil of Anand (Gujarat) during summer season of the year 2017 to study the effects of multi-micronutrient mixture on growth, yield and quality of the pearl millet (Pennisetum glaucum L.). The soil used for the experiment was alkaline in reaction with low in available N and high in available P2O5 and K2O. With respect to DTPA-micronutrients, Fe and Mn was deficient, while Zn and Cu were sufficient in status. The higher grain yield was obtained with the 1% foliar spray of multi-micronutrient mixture grade-III (for Fe deficiency) having concentration of Fe-6.0%, Mn-1.0%, Zn-4.0%, Cu-0.3% and B-0.5% at 15, 30 and 45 DAT (Days after Transplanting). While straw and total yield was higher under the soil application of micronutrients of 50 kg FeSO4.5H2O ha-1 and 40 kg MnSO4.3H2O ha-1 as per STV (Soil Test Value). Micronutrient supplementation through 1.0% foliar application of the mixture having concentration of Fe-4.0%, Mn-1.0%, Zn-6.0%, Cu-0.5% and B-0.5% (Grade-IV for Zn and Fe deficiency)was also found beneficial in increasing ear head length, grain, straw and total yield of summer pearl millet. | Effects of multi-micronutrient mixture on growth, yield and quality of the summer pearl millet (Pennisetum glaucum L.)
