    Effect of different tillage and weed management practices on wheat yield and soil properties
    (CCSHAU, 2017) Kavita; Dahiya, D.S.
    An ongoing field experiment established in 2012 at Agronomy Research Farm, CCS Haryana Agricultural University, Hisar, India was selected to study “Effect of different tillage and weed management practices on wheat yield and soil properties”. The experiment was laid out with three different tillage (zero tillage, FIRBS and conventional tillage) and four weed management practices (W1: Atrazine (50% W.P.) @ 750 g/ha in maize and pinoxaden 50g/ha + premix of metsulfuron and carfentrazone (Ally Express 50% DF) 25g/ha + 0.2 % NIS as post-emergence in wheat, W2: Tembotrione (Laudis 42% Sc @ 120 g/ha + S 1000ml/ha (10-15 DAS / 2-4 leaf stage) in maize and clodinafop 60 g/ha + metsulfuron 4 g/ha as post- emergence in wheat, W3: Two HW in maize (20 to 40 DAS) and wheat (30 to 50 DAS), W4: Weedy check in maize and wheat) at two different depth (0-5 & 5-15 cm) were replicated thrice in spilt plot design. Plant and soil samples for analysis were collected after 4 cycle of maize-wheat cropping system in the month of April, 2016 after the harvesting of wheat crop. A significant higher yield reported under FIRBS (66.1 qha-1) method of tillage as compared to other tillage practices. pH and EC reported higher under conventional tillage under different tillage and weed management practices. SOC (0.896%), N (100.57 kg ha-1), P (32.61 kg ha-1), S (18.21 kg ha-1), HA-C (0.352%) and FA-C (0.239%) reported higher under zero tillage due to more retention of crop residue on surface. However, a reverse trend was obtained in case of available K. Values of Zn, Fe and Cu was also recorded higher under zero tillage while value of Mn reported higher under conventional tillage. Most of the nutrients values reported higher at upper depth (0-5 cm) and under weedy check treatment. DOC followed reverse trend as compared to other parameters and higher values reported under conventional tillage. Highest values of MBC (336.02 mg kg-1) was noticed under zero tillage and at 0-5 cm depth. All enzymes (Dehydrogenase, alkaline phosphatase and urease) activities reported higher under ZT. Dehydrogenase and urease activity reported higher at upper depth (0-5cm) while activity of alkaline was higher at lower depth (5-15 cm). At the end of season weed management practices showed non-significant effect on MBC and all enzymes. Bulk density of soil reported higher under CT as compared to other tillage practices.
