Abstract:

A field investigation entitled “Effect of sequential application of pre-emergence and post emergence herbicides on weeds, productivity and profitability of maize (Zea mays L.)” was carried out at AICRP on weed management field of Agronomy Department, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the Kharif season of the year 2018-19 with an objective to study the relative efficacy of pre and post emergence herbicides on weed control in maize and to study its effect on productivity and profitability of maize. The experiment was laid out in randomized block design with twelve treatment replicated thrice. The soil of experimental field characterized as clay loam in texture, having slightly alkaline pH (7.5), moderate organic carbon status (5.38%), low nitrogen content (219.33 kg ha-1), medium available phosphorus content (15.30 kg ha-1) and high available potassium (340.67 kg ha-1). Maize (Pioneer hybrid 3396) was sown on 25th June 2018 at 60×20 cm spacing with 120:60:30 NPK kg ha-1. The results revealed that among the herbicidal treatments, Atrazine 0.50 kg/ha fb tembotrione 0.120 kg/ha was found to be effective in controlling weeds across the crop growth period., Among the various treatments under study weed free recorded significantly higher values of major parameters whereas, in herbicidal treatments, the maximum growth and yield attributes were recorded with treatment Atrazine 0.50 kg/ha fb tembotrione 0.120 kg/ha which was at par with Atrazine 0.50 kg/ha fb 2,4-D sodium salt @0.5 kg/ha. Among the post emergence herbicides, reduction in weed population, weed dry matter, higher weed control efficiency (79.78) and lowest weed index (7.62) was found with Atrazine 0.50 kg/ha PE fb tembotrione 0.120 kg/ha POE 20 DAS. Atrazine 0.50 kg/ha fb tembotrione 0.120 kg/ha was found most economical with maximum value of GMR (75709 Rs ha-1) , NMR ( 53059 Rs ha-1 ) and B: C ratio (3.34).
