Abstract:
A research was done to ascertain its impact of various nutrient treatments in rice crop at Crop Research farm, Maharishi Markandeshwar (deemed to be university) Mullana, Ambala, Haryana during kharif 2022 on sandy loam soil, low levels of accessible nitrogen and organic carbon, phosphorous, zinc as well as iron likewise, medium to high in available potassium and marginally alkaline in reaction. The experiment was conducted in Randomized block design comprising 10 treatments (T₁: Control, T₂: 100% NPK, T₃: 100% NPK + 25 kg ZnSO₄, T4: 100% NPK + 25 kg FeSO₄, T₅: 100% NPK + 25 kg ZnSO₄ + 25 kg FeSO₄, T₆: 100% NPK + 12.5 kg ZnSO₄ + 12.5 kg FeSO₄ + VAM (5 kg mixed in 50 kg FYM and broadcasted), T₇: 100% NPK + Zn EDTA + Fe EDTA, T₈: 100% NPK + 0.5% ZnSO₄ at Tillering and panicle initiation, T₉: 100% NPK + 0.5% FeSO₄ at Tillering and panicle initiation and T₁₀: 100% NPK + 0.5% ZnSO₄ + 0.5% FeSO₄ at Tillering and panicle initiation. From this investigation it was observed that maximum plant growth and its attributes viz. Plant height, No. of tillers, Dry matter accumulation and Leaf area index was observed under T₁₀: 100% NPK + 0.5% ZnSO₄ + 0.5% FeSO₄ at Tillering and panicle initiation.
