| Popis: | A field experiment conducted to evaluate the impact of integrated weed management on economics of Kharif maize (Zea mays L.) during Kharif, 2020 at Post Graduate Research Farm, RCSM College of Agriculture, Kolhapur. The field experiment was laid out in Randomized Block Design (RBD) having eight treatments replicated thrice.Weed free check and tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS + fb hand weeding at 40 DAS were on par with each other and recorded significantly increase in grain and straw yields of maize as compared to remaining weed management treatments. Significantly lowest values for yield and yield attributes was observed in weedy check treatment.Maximum gross monetary returns and net monetary returns were observed in weed free check treatment was Rs. 183225.5 ha-1 and Rs. 126320.7 ha-1, respectively. Tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS recorded maximum B: C ratio (3.34). |
