Effect of treatments on yield attributes of irrigated wheat (Triticum aestivum L.)

Abstract

The field experiment was conducted during Rabi season of 2015-2016 to observe the effect of Vermicompost, FYM, Azotobacter and inorganic fertilizers on yield of wheat (Triticum aestivum L.)” The 8 treatments were tested in Randomized Block Design with three replication (T1 RDF 120:60:40 Kg NPK), T2 RDF + Azotobacter, T3 RDF+Azotobacter+ Vermicompost @ 3.0 t/ha, T4 RDF +Azotobacter+ Vermicompost @ 4.0 t/ha, T5 RDF +Azotobacter+ Vermicompost @ 5 t/ha, T6 RDF +Azotobacter+ FYM @ 4.0 t/ha, T7 RDF + Azotobacter+FYM @ 8.0 t/ha, T8 RDF +Azotobacter+ FYM @ 12.0 t/ha ) The soil of field was sandy loam The pH of soil was 7.30. The wheat variety PBW-343 was sown on 30 of Nov. 2015 at row spacing 20 cm with seed rate of 100 kg/ha. Full dose of phosphorus and potash was applied as basal doses at the time of sowing and the nitrogen was applied as per treatment. The source of nitrogen, phosphorus and potash was organic and inorganic fertilizers respectively. Result showed that the treatment T5 gave the significantly better growth of plant yield contributing characters. The treatment T5 recorded the highest grain yield (55.57 q/ha). The minimum grain yield (38.61 q/ha) was recorded under the treatment T1 (RDF 120:60:40 NPK kg/ha).
