Abstract:
Field research was conducted at the Department of Agriculture research farm, Maharishi Markandeshwar (Deemed to be University), Mullana, Ambala while the Rabi season of 2022. with eight treatments, In order to set up the experiment, a randomised block design was used: T₁: (Recommended dose of urea + SSP (S 15), T₂: (Recommended dose of urea + double dose of SSP (S 30), T₃: (Single dose of DAP remaining N through urea + Bentonite (S 15), T₄: (Single dose of DAP remaining N through urea + Bentonite (S 30), T₅: (Single dose of DAP remaining N through urea + Bentonite (S 45), T₆: (Double dose of DAP remaining N through urea + Bentonite (S 15), T₇: (Double dose of DAP remaining N through urea + Bentonite (S 30) and T₈: (Double dose of DAP remaining N through urea + Bentonite (S 45). In this research the hybrid variety of Rapeseed (Brassica campestris L.) (sagar-86) was taken. The results from the data under this research revealed that by the application of (Double dose of DAP + Bentonite (S 45) the recorded highest in all parameters like growth attributes, yield and its attributes and economics. Highest grain yield, stover yield and biological yield was (1.60, 2.88 and 4.48 t ha^-1) respectively. Among all the treatments, the application of (Double dose of DAP remaining N through urea + Bentonite (S 45) recorded highest in all plant height at harvest, at 30, 60, and 90 DAS, as well as when dry matter builds up occasionally, are examples of growth parameters. Yield and its attributes like test weight, grain yield and stover yield and biological yield was also observed under T₈ (Double dose of DAP remaining N through urea + Bentonite (S 45).
