Verification of Potassium, Zinc and Boron Fertilizer on Yield of Wheat (Triticum aestivum) in Jamma and Meket Districts of East Amhara

摘要

Soil fertility map of the region developed by ATA and Ministry of Agriculture and Natural Resources indicates 100% of the Jamma and Meket district shows potassium deficiency. In addition to potassium 100% of Jamma districts and more than of 98% of Meket district also shows both NPSB and NPSBZn deficiency. This study was conducted in Eastern Amhara National, Regional State of Meket and Jamma districts in the 2017 cropping season to verify crop responses to potassium, Boron and Zinc fertilizers visa- via the soil fertility map of the districts developed by ATA and Ministry of Agriculture and Natural Resources. Five sites per district were selected for the study. The test crop was wheat (Dinkenesh). The treatments were: NPS, NPSK, NPSBZn and NPSKBZn. Treatments were replicated three times per site and the design was RCBD. Recommended NP was used uniformly for all treatments. The collected data were subjected to analysis of variance using SAS version 9. The Result reveald that there was no statistical significance yield difference (p 0.05) between potassium, boron and zinc treated plots and recommended NP plots. For all sites the finding was unrelated to the developed soil fertility map. Therefore; it is unjustified to use K, B and Zn fertilizers for the study crops and areas.
