An experiment was conducted during the winter (rabi) season of 2021–22 to evaluate the effect of integrated nutrient management on the growth and yield of yellow sarson under guava based agri-horti system. The field ex- periment comprised 8 treatment, viz., T1 , Control; T2 , 100% RDF + 30 kg S + 5 kg Zn; T3 , 50% RDF + 15 kg S + 2.5 kg Zn + 2.5 t/ha FYM+ 2 spray of nano urea; T4 , 50% RDF + 15 kg S + 2.5 kg Zn + 5 t/ha FYM+ one spray of nano urea; T5 , 75% RDF + 22.5 kg S + 3.7 kg Zn + 2.5 t/ha FYM + 2 spray of nano urea; T6 , 75% RDF + 22.5 kg S + 3.7 kg Zn +5 t/ha FYM + 1 spray of nano urea; T7 , 100 % RDF + 30 kg S + 5 kg Zn + 2.5 t/ha FYM; T8 , 100% RDF + 30 kg S + 5 kg Zn + 5 t/ha FYM, was laid out in randomized block design, with 3 replications. The results revealed that application of 75% RDF + 22.5 kg S + 3.7 kg Zn +2.5 t/ha FYM + 2 spray of nano urea at 30-35 DAS and pre-flow- ering stage (T5 ) gave significantly higher growth and yield attributes such as plant height (141.03 cm), dry matter accumulation (37.76 g/plant), no. of siliqua (142/plant), siliqua length (6.67 cm), test weight (3.43 g) as well as seed yield (1.49 t/ha) and stover yield (3.54 t/ha) as compared to control. The highest amount of nitrogen, phos- phorus, potassium and sulphur uptake by plant was also observed in the treatment T5. These findings provide valuable insights for farmers and researchers aiming to optimize nutrient management strategies and improve crop productivity in similar agri-horti systems.
