tailieunhanh - Performance of crop residue management practices on growth and yield of wheat (Triticum aestivum L.) under rice- wheat system in Bastar region of Chhattisgarh, India

A field experiment conducted during the Rabi season, 2016-17 at the Instructional Farm, Shaheed Gundadhoor College of Agriculture & Research Station, Kumhrawand, Jagdalpur District- Bastar (Chhattisgarh). The soil of experimental site was sandy loam; it was low in organic carbon () and available nitrogen ( kg ha-1 ) and medium in available phosphorus ( kg ha-1 ) and potassium ( kg ha-1 ) and acidic in reaction ( pH). The experiment was laid out in spilt plot design with three crop residue management practices and four varieties of wheat. Three residue management practices viz. Residue burnt + tillage (T1), Residue incorporation (T2) and Residue retention (T3), were applied in main plot and four varieties viz. GW- 273 (V1), Lok- 1 (V2), Kanchan (V3) and Sujata (V4) in sub-plot and replicated 3 times. The results revealed that treatment residue retention recorded relatively higher plant height ( cm) at 15 DAS, whereas treatment residue incorporation recorded relatively higher plant height ( cm) at 30 DAS, ( cm) at 45 DAS and ( cm) at 60 DAS, ( cm) at 75 DAS, ( cm) at 90 DAS and ( cm) at harvest. The varieties GW-273 recorded significantly higher plant height ( cm) at 15 DAS and ( cm) at 30 DAS, variety LOk-1 recorded significantly higher plant height ( cm and cm) at (45 and 60 DAS) respectively. | Performance of crop residue management practices on growth and yield of wheat (Triticum aestivum L.) under rice- wheat system in Bastar region of Chhattisgarh, India
