Statistical effect of irrigation levels and weeds management in wheat (Triticum aestivum L.) in Northern-Hill zone of (Chhattisgarh)

Abstract:
A field experiment was carried out for two consecutive years in rabi seasons of 2017-18 and 2018-19 at Research Cum Instructional Farm, IGKV, Lt. Dr. Ramchanra Singh Dev College of Agriculture and Research Station, Baikunthpur, Korea, Chhattisgarh. The soil of experimental field was Vertisols, neutral in reaction, low in available nitrogen, and medium in available phosphorus and high in available potassium. The experiment was laid out in Split Plot Design with three replications. The main plot treatment consisted of 03 Irrigation levels I1: 0.8 IW/ CPE, I2: 1.0 IW/ CPE, I3: 1.2 IW/ CPE and Sub-plot treatment consisted of 06 Weed management i.e. W1: Sulfosulfuran (20 g ha-1), W2: Clodinofop (60 g ha-1), W3: Metsufuron (4 g ha-1), W4: Clodinofop + Metsulfuran (60 g + 4 g ha-1), W5: Sulfosulfuran + Metsulfuran (20 g + 4 g ha-1), W6: Unweeded Control. The finding revealed that the irrigation in wheat at I3: 1.2 IW/CPE recorded significantly highest grain and straw yields under this treatment. As regards to weed management practices in wheat, treatment W4: Clodinofop + metsulfuron (60 g+4 g ha-1) registered significantly highest yield attributes and grain and straw yields and harvest index as compared to others. Total weed density and weed dry weight recorded at 40 and 80 DAS during both the years. The effect of different irrigation levels was non- significant affect on total weed density and weed dry weight of wheat. It was observed that weed density and weed dry matter were low in case of I1: 0.8 IW / CPE irrigation level. The treatment I3: 1.2 IW/ CPE irrigation level recorded maximum weed density and weed dry weight due to availability of more water for germination of weed seeds present on the top of the soil. The increase in density and dry weight weeds to such an irrigation level under treatment I3: 1.2 IW/ CPE might be attributed to uninterrupted growth of weeds throughout the crop season and more competitive nature than crop up to the harvest. Heavy weed infestation and dry weight under unweeded control have also been reported by many scientists such as Singh and Singh (2005), Hari et al. (2006), and Koli (2006).
