Effect of rates and concentration of urea solutions applied as a late foliar spray on grain yield and quality of winter rye


, : Effect of rates and concentration of urea solutions applied as a late foliar spray on grain yield and quality of winter rye. Nauchnye Trudy Udmurtskoi Sel' skokhozyaistvennoi Opytnoi Stantsii (5): 45-48

In trials with winter rye given a foliar spray of 15-75 kg N/ha as 5-25% urea sol. at the flowering/earing stage, increasing the N rates and concentration of the sol. increased grain yields to 3.04 t/ha and grain protein contents to 12.1%, compared with 2.58 t and 9.8%, resp., without N. The yield response/kg N at 75 kg/ha was 7.5 kg grain. The opt.

Hypertension is characterized by a pro-inflammatory status, including redox imbalance and increased levels of pro-inflammatory cytokines, which may be exacerbated after heat exposure. However, the effects of heat exposure, specifically in individu...

It has also been shown to slow axon regeneration after peripheral nerve injury and inhibit axon regeneration in the optic nerve. Her...
