Abstract

SUMMARY newlineA field experiment entitled Effect of sowing dates and herbicides on growth and yield of Wheat (Triticum aestivum L.) and associated weeds was conducted at Department of Agronomy, T. D. P. G. College, Jaunpur (Uttar Pradesh) in Rabi season of 2018-19 and 2019-20 with following objectives: newline1. To study the effect of sowing dates and weed control measures on growth of weeds. newline2. To assess the effect of sowing dates and weed control measures on growth and yield attributes of Wheat. newline3. To find out the interaction effect of different sowing dates and weed control measures on growth of weeds and their successive effect on Wheat. newline4. Economics of treatment combination. newlineThe present investigation was conducted at the at Department of Agronomy, T. D. P. G. College, Jaunpur (Uttar Pradesh) in Rabi season of 2018-19 and 2019-20 during rabi season of 2018-19 and 2019-20. The district of Jaunpur is situated in the North-West part of Varanasi Division. Its land area extends from 24.240N to 26.120N latitude and between 82.70E and 83.50E longitudes. The district is made up of shallow river valleys and flat plain with the main rivers being Gomti and Sai. The land of the region slopes in the same direction as that of the flow of these rivers. Thus, there is a more elevated area in the northwest and a less elevated area of land in the south east. Jaunpur district has a climate consistent with that of the Northern Plain and Central Highlands including the Aravalli range, hot semi-arid eco-region 4.3 and hot dry ecoregion 9.2. The temperature varies between about 4 °C (39 °F) and 44 °C (111 °F).The annual normal rainfall is 1,098 millimetres (43.2 in). The monsoon season occurs from the third week of June to the first week of October. Normally, there are 46 rain days per year of which 31 occur in the monsoon season. The district regularly suffers drought and pestilence. The climatic condition of Jaunpur district is approximately like adjacent Varanasi district, so the detailed weather parameters of Varanasi district can be use
