Abstract
The present investigation entitled “Effect of Herbicide Combinations on Growth and Yield of Kharif Maize (Zea mays L.)” was carried out during kharif 2019 at College Farm, College of Agriculture, Badnapur, Dist.-Jalna. Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, Maharashtra (India). Randomized Block design was used for study comprised of ten treatments. Among treatments, weed free treatment attributed more number of leaves, maximum plant height, dry matter production and leaf area per plant followed by treatment of topramezone 33.6 % SC @ 25.2 g a.i.ha-1 + atrazine 50 % WP @ 250 g a.i. ha-1. Poor growth attributes were recorded in weedy check. Significantly maximum values of yield attributes were recorded in treatment of topramezone 33.6 % SC @ 25.2 g a.i.ha-1 + atrazine 50 % WP@ 250(g)a.i.ha-1 followed by treatment of tembotrione 42 % SC @ 105 g a.i. ha-1+ atrazine 50% WP @ 250 g a,i. ha-1. Minimum values of yield attributes were attributed in weedy check. Treatment of topramezone + atrazine @ 25.2 + 250 g a.i ha-1 as PoE (T6) found effective in limiting weed growth and recorded lower weed index, weed dry matter with higher weed control efficiency followed by tembotrione +atrazine @105 + 250 (g) a.i.ha-1as PoE (T7) at all growth stages of crop. The benefit cost ratio was highest (2.94) with application of topramezone + atrazine @25.2 + 250 g a.i ha-1 followed by tembotrione + atrazine @ 105 + 250 g a.i. ha-1 as PoE (2.81) whereas weedy check recorded significantly lower B:C ratio(1.50) over other treatments.
