Abstract:
A field experiment was conducted to study the effect of partial root drying technique and fertigation on leaf nutrient status of pomegranate (Punica granatum L.) Cv. Bhagwa. The experiment comprising of 8 treatments, T₁: Partial root drying technique (100% water requirement) + 100% nutrition (NPK), T₂: Partial root drying technique (100% water requirement) + 75% nutrition (NPK), T₃: Partial root drying technique (75% water requirement) + 100% nutrition by fertigation with 100% RDF of NPK, T₄: Partial root drying technique (75% water requirement) + 75% nutrition by fertigation with 75% RDF of NPK, T₅: Partial root drying technique (50% water requirement) + 100% nutrition by fertigation with 100% RDF of NPK, T₆: Partial root drying technique (50% water requirement) + 75% nutrition by fertigation with 75% RDF of NPK, T₇: Control i.e. normal drip irrigation (100% water requirement) + 100% nutrition by fertigation with 100% RDF of NPK, T₈: Control i.e. normal drip irrigation on both sides of the plant (100% water requirement) + 75% nutrition by fertigation with 75% RDF of NPK. During flowering stage, the maximum nitrogen (1.95%), potassium (1.95%), calcium (2.10%) and magnesium content (0.57%) was recorded in I₂N₁ treatment. Coming to harvest stage, maximum nitrogen content (1.53%), maximum potassium of 1.40% (I4N2 treatment also). Whereas, maximum calcium (0.49%) was observed in I₂N₂ treatment.
