Abstract:
The field experiment was conducted during 2017-18, 2018-19 on Inceptisol at Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). The experiment was laid out in randomized block design with three replications and nine treatments. The treatments were comprise of variable doses of gypsum and phosphogypsum application, recommended dose of fertilizers and an absolute control. During both the years, the DTPA extractable Fe, Mn, Zn and Cu was significantly higher with the application of RDF (S free) along with phosphogypsum @ 400 kg ha^-1 at 45, 70, 95 DAS and at harvest. However, the micronutrients content was statistically on par with RDF (S free) with soil application of phosphogypsum @ 300 kg ha^-1 at 45 DAS. With regard to available boron content, slight decline was noted with an advancement of growth stage of groundnut. The available boron in root zone of groundnut was found significantly higher with RDF (S free) with the application of phosphogypsum @ 200, 300 and 400 kg ha^-1 (0.40 mg kg^-1) at 70 DAS.
