Abstract:
The major problems causing yield reduction of barley in India is declining soil fertility. Therefore, considering this in view a field experiment entitled, “Nutrient studies of barley as influenced by various combinations of nitrogen fertilizer, biomix and vermicompost” was conducted at the Agronomy Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar during the rabi season of 2017-18. The objective of the experiment was to evaluate the effect of different nutrient management practices on nutrient content and uptake of barley. The soil of the experimental field is sandy loam in texture, slightly alkaline in reaction, low in organic carbon and nitrogen, medium in available phosphorus and potassium. The experiment was laid out in Randomized Block Design replicated thrice with ten different treatments viz. T1(Control), T2 (Biomix), T3 (Vermicompost @ 5 t ha-1), T4 (Biomix + Vermicompost @ 5 t ha-1), T5 (50% RDN + Vermicompost @ 5 t ha-1), T6 (75% RDN + Vermicompost @ 5 t ha-1), T7 (50% RDN + Biomix + Vermicompost @ 5 t ha-1), T8 (75% RDN + Biomix+ Vermicompost @ 5 t ha-1), T9 (RDN) and T10 (RDN + Biomix + Vermicompost @ 5 t ha-1). Among various nitrogen management practices treatment T10 produced significantly higher N content and uptake in grain and straw and total N uptake of barley followed by treatment T9 and T8. Markedly, highest value of P content and uptake in grain and straw and total P uptake was recorded in treatment T10, followed by treatment T8 and T9. Treatment T10 recorded highest value of K content in grain and straw, K uptake by grain and straw and total K uptake. There was no significant effect of various combinations of nitrogen fertilizer, biomix and vermicompost on straw K content of barley. There was no significant difference due to application of various combinations of nitrogen fertilizer, biomix and vermicompost on N, P and K status of soil after harvesting of barley.
