The present experiment on wheat (Triticum aestivum L.) was conducted during two consecutive Rabi season 2021-22 and 2022-23 at MPUAT, Udaipur, Rajasthan. The field research consisted of 9 treatments which are replicated thrice in a Randomized Block Design (RBD). Nowadays, farmers are trying to get maximum yield with better food quality, at the same time trying to minimize cost of production and to use ecofriendly technologies. There are many factors which influence the concentration of nutrients and among them climatic situation, soil types, nature of crops and amount of fertilizer are important. Hence, the present research is proposed with the objective to study the content of nitrogen, phosphorus and potassium in grain and straw of wheat. The results show of two year study indicated that application of SSP, rock phosphate tailing and seed treatment with PSB significantly increased the concentration of nutrients in grain and straw of wheat by providing different combination of phosphorus sources. The study revealed that application of 50% RDP through SSP + 50% RDP through RPT + PSB statically at par with 75% RDP through SSP + 25% RDP through RPT + PSB and significantly superior over 25% RDP through SSP + 75% RDP through RPT + PSB, 100% RDP through SSP + PSB, 100% RDP through SSP, 100% RDP through RPT + PSB, 125 RDP through RPT + PSB, 100% RDP through RPT and as well as control treatment. Therefore, 50% RDP through SSP + 50% RDP through RPT + PSB treatment is best combination for getting higher nutrient content in grain and straw and grain yield.

SSP, RDP, rock phosphate tailing, PSB, Wheat

Application of phosphorus fertilizer through single super phosphate, rock phosphate tailing and seed inoculation with PSB in combination of 50% RDP through SSP + 50% RDP through RPT + PSB (T5) significantly increased the nutrient content and grain yield of wheat when compared to other treatments such as T4 (75% RDP through SSP + 25% RDP through RPT + PSB), T6 (25% RDP through SSP + 75% RDP through RPT + PSB), T3 (100% RDP through SSP + PSB), T2 (100% RDP through SSP), T7 (100% RDP through RPT + PSB), T8 (125% RDP through RPT + PSB), T9 (100% RDP through RPT) and T1 (control).
