Abstract

It has been observed that application of lower rates of fertilizer affects production and quality of grain below acceptable levels because they reduce nutrient transfer from vegetative components to grain. Therefore, an appropriate dose of nutrients should be made available to crop plants. For resolving this issue a field trial was carried out during rabi 2020-21 and 2021-22 at Agronomy farm, MPUAT, Udaipur with the aim to assess the response of malt barley to fertilizer’s dose and biofertilizers. The experiment used a randomised block design (Factorial) with 15 treatment combinations consisting of three fertility levels i.e. application of 50 kg N + 25 kg P2O5 +15 kg K2O ha-1, 60 kg N + 30 kg P2O5 +20 kg K2O ha-1 and 70 kg N + 40 kg P2O5 +25 kg K2O ha-1 with five liquid biofertilizers i.e. control, Azotobacter, PSB, KMB and Azotobacter + PSB + KMB. The results discovered that, malt barley crop fertilized with 70 kg N +40 kg P2O5 + 25 kg K2O ha-1 along with seed inoculation with Azotobacter + PSB + KMB accumulated maximum quantum of nutrients in grain, straw and thereby total.

Conclusion

Based on the results emanated, it is concluded that combine application of 70 kg N + 40 kg P2O5 + 25 kg K2O ha-1 + seed inoculation with Azotobacter + PSB + KMB accumulated maximum quantum of nutrients in grain and straw of malt barley crop.
