EFFECT OF WEED CONTROL METHODS ON GROWTH, DRY MATTER ACCUMULATION AND YIELD OF MAIZE
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
Maize (Zea mays), is the third most important cereal crop in the world after wheat and rice. Management of weeds is considered to be an important factor for achieving higher productivity as weed problem is more severe during continuous rains in early stages of maize growth which cannot be controlled by traditional and cultural practices alone due to too much wetness. The present study aimed to study the effect of different weed control methods on growth, dry matter accumulation and yield of maize. The experiment was conducted at Main Agricultural Research Station (MARS), College of Agriculture, Dharwad during 2014. Six herbicides were used in nine treatments using Randomized Block Design having three replications.T8 (weed free check) was recorded significantly higher leaf area, dry matter production, grain yield and stover yield than all other treatments. The next best treatments were T7 (Atrazine @ 1 kg ha-1 + 2 IC + 1 HW), T4 (Atrazine @ 1 kg ha-1 fbSaflufenacil @ 75 g ha-1) and T2 (Atrazine @ 1 kg ha-1 fbParaquat @ 1 kg ha-1).
