Description |
A field experiment was conducted at Agronomy research farm, CCS Haryana Agricultural University, Hisar, Haryana during kharif 2012. Three pre-emergence herbicides viz., atrazine 750 g/ha, atrazine 500 g/ha+1 HW 35 DAS and pendimethalin 1000 g/ha and one post-emergence herbicides viz., tembotrione (Laudis 42% SC) 120 g/ha + S 1000 ml/ha (10-15 DAS/2-4 leaf stage) were compared with weed free and weedy check. Three main plot treatments and six sub plot treatments were tested using a split plot design with four replications. Climatic data revealed that rainfall received during the experimental period was 393.6 mm which was 26.1 mm more than the normal rainfall of the past 30 years. During cropping season, 321.7 mm rainfall was received. It was well-distributed up to October which resulted in good crop stand and growth. Important weed species observed in the experimental plots were Cyperus rotundus, Echinochloa colona, Trianthema portulacastrum and Digera arvensis. Application of atrazine 750 g/ha recorded significantly lower weed population, dry weight of weeds and higher weed control efficiency at all growth stages with good crop growth. Whereas, in planting methods, zero tillage recorded lowest weed population, dry weight of weeds and higher weed control efficiency at all growth stages with good crop growth. In weed control method, effective control of weeds, higher grain and stover yield, net income and B:C were obtained with application of atrazine 750 g/ha, whereas in planting methods, zero tillage recorded higher grain and stover yield, net income and B:C. |
