Abstract:

A field study was conducted during kharif 2020-21 at Research farm of AICRP on Weed Management, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra to Effect of Fertigation Levels and Weed Management on Yield and Nutrient Uptake by Maize in Inceptisols. The soil of the experimental site was Inceptisol which was moderately alkaline in reaction, low in available nitrogen, medium in available phosphorus and medium in available potassium, deficient in available sulphur, zinc and iron, whereas fairly high in available Cu and Mn. The experiment was laid out in split plot design with three replications. The twenty treatments consisting of four different of fertigation levels and five different of weed management practices. The main plot treatments comprised of different levels of fertilizer in five splits at 75 per cent, 100 per cent and 125 per cent of recommended dose of N and K of fertilizers given through fertigation, however P was applied as basal dose and these treatment were compared with 100 per cent soil application of fertilizers. Whereas, sub plot treatments comprised of five weed management practices viz., Atrazine+ Tembotrione, Atrazine + Topramezon, Atrazine + Halosulfuron, Farmers practices and weedy ckeck. The yield found to be lowest with 75 per cent RDNK and highest with 125 per cent RDNK (5 splits). Among the various weed management practices under study farmers practice (2 hoeing 15-20 Days interval after sowing followed by 2 HW) recorded significantly higher values of major parameters. The nutrient uptake by weeds was lowest in weedy check condition. However, total nutrient uptake by crop was observed maximum in farmers practices followed by Atrazine 0.75 kg/ha PE followed by Topramezone 0.0252 kg/ha POE 20 DAS.
