Abstract:
Field research was carried out during rabi 2017-18 at the College Farm, Navsari Agricultural University, Navsari on “Integrated weed management in rabi popcorn (Zea mays L. var. everta) under South Gujarat condition”. The experimental soil was clayey in texture, low in available nitrogen (164 kg ha^-1), medium in available phosphorus (42 kg ha^-1) and high in available potash (315 kg ha^-1). Results revealed that in the case of different growth, yield attributes and yield, the treatment T₉ was performed better than all the other treatments but statistically remained at par with T₆, T₅ and T₄. However, plant population and per cent barren plant were not influenced significantly. Pop corn yield was significantly affected by different weed control methods therefor higher grain (3748 kg ha^-1) and stover yield (7898 kg ha^-1) were registered with T₉ but which is being statistically at par with T₆, T₅ and T_4. The N, P and K content (%) in grain, stover and weed were done not exert its significant influence, while higher N, P and K, kg ha^-1 uptake was reported by grains and stover under the T₉, which was statistically at par with T₆, T₅ and T₄. While higher uptakes of nutrients were registered under T₁₀ fb T₁, T₇ and T₃. Protein content (%) in grains failed to exert its significant effects. T₉ produced significantly maximum protein yield which was statistically at par with T₆ and T₅. After harvesting of the crop, available N, P and K kg ha^-1 were recorded significantly maximum under T₉ fb T₆, T₅ and T₄. The maximum net realization (Rs 72143 ha^-1) was gained from T₆ fb T₅ and T₄. However, the maximum B: C ratio was recorded by treatment T₅ (2.96) followed by T₆ and T₉.
