Effect of formulations of nano phosphorus and nano phosphorus conjugate on growth and yield of Mustard (Brassica juncea L.) in Konkan region

A field experiment was carried out during rabi season of 2023-24 at Instructional Farm, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, College of Agriculture, Dapoli, Dist. Ratnagiri, Maharashtra on to study the Effect of Formulations of Nano phosphorus and Nano phosphorus conjugate on growth and yield of Mustard (Brassica juncea L.) in Konkan region. The experiment was laid out in split plot design with fifteen treatment combinations replicated thrice. The main plot consisted of three phosphorus sources: P₁ – Nano phosphorus, P₂ – Nano phosphorus conjugate, P₃ – Nano DAP (Market product), the sub-plot consisted of five levels of concentrations: C₁ – 0 ppm, C₂ -25 ppm, C₃ – 50 ppm, C₄ – 75 ppm and C₅ -100 ppm. The result was obtained that, the phosphorus sources P₂ (Nano phosphorus conjugate) and concentration C₅ (100 ppm) recorded significantly higher plant height, higher number branches plant^-1, dry matter production, seed yieldand straw yield (kg ha^-1) in Mustard.
