Comparative Studies of Potassium Humate with Fertilizer and Vermicompost on Yield Attribute, Yield and Economies of Late Sown Wheat (Triticum aestivum L.)

Abstract:

Wheat (Triticum aestivum L.) has been regarded as the “king of cereals” and one of the most important staple food crops farmed in at least 43 nations throughout the world. Due to the continuous increase in population, the demand for wheat is also increasing to meet demand. Integrated Nutrient Management (INM) is a useful way to maintain/adjust soil fertility to an optimum level for crop productivity in order to gain the most benefit from all feasible sources of plant nutrients, both organic and inorganic, in an integrated manner. Regarding this a field experiment entitled “Comparative studies of potassium humate with fertilizer and vermicompost on late sown wheat (Triticum aestivum L.)” was conducted at the Student’s Instructional Farm of the Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. The experiment was laid out in Randomized Block Design with 3 replication and 8 treatments consisting of viz. 100% RDF, 75% RDF, 75% RDF + VC @ 3.0 t/ha and 100% RDF+ VC @ 3.0 t/ha, Control (No potassium humate), Potassium humate (3.0 kg/ha), Potassium humate (2.5 kg/ha) and Potassium humate (2.0 kg/ha). It was found that highest grain yield (44.34 q ha¹) was received with 100% RDF+ VC @ 3.0 t/ha followed by (42.38 q ha¹) in 75% RDF + VC @ 3.0 t/ha as well as potassium humate @ 3.0 kg/ha was also obtained higher yield as compared to control treatment during the experimental period. While net profit was highest (Rs. 23368 ha¹) in the treatment 100% RDF+ VC @ 3.0 t/ha followed by 100% RDF (Rs. 17368 ha¹). The minimum grain yield (34.79 q/ha) and net profit (Rs 6116.00 ha¹) was received in control plot and B:C ratio was also highest (1.46) in 100% RDF + VC @ 3.0 t/ha followed by 100% RDF (1.39) as well as potassium humate @3.0 kg/ha was obtained highest benefit : cost  ratio of (1.36).
