Abstract:
Field experiment was conducted at Department of Agronomy, College of Agriculture, Dhule during Kharif 2019 to study the effect of pre and post emergence herbicides viz., atrazine, halosulfuron methyl, 2-4-D ethyl ester, pendimethalin and tembotrione on nutrient uptake by sweet corn. The weed free treatment (T2) with two hand weeding recorded significantly higher total N, P and K uptake of 253.16, 84.36 and 259.13 kg ha-1, respectively, by sweet corn. However, significantly lower total N, P and uptake of 104.60, 31.98 and 109.94 kg ha-1, respectively, by sweet corn was recorded in the treatment of weedy check (T1). Among the treatments of pre and post emergence herbicides, application of pendimethalin @ 1000 g ha-1 as pre emergence fb tembotrione @ 120 g ha-1 as post emergence (T6) recorded higher total N uptake (230.22 kg ha-1), P uptake (72.37 kg ha-1) and K uptake (240.85 kg ha-1) by sweet corn with 120, 126.29 and 119.07 % increase, respectively, over the treatment of weedy check (T1) and 9.06, 14.21 and 7.05 % decrease, respectively, over the Weed free (T2) treatment (Two hand weeding).
