Impact of Integrated Nutrient Management Practices on Chemical Properties of Soil under Finger Millet Cultivation in Assam, India

A field experiment was carried out during the rabi season of 2022-2023 at Instructional-cum-Research Farm, Assam Agricultural University, Jorhat to evaluate the performance of different integrated nutrient management practices on chemical properties of soil under finger millet cultivation in rainfed upland condition. The design of the experiment was randomized block design (RBD) with three replications. Individual plot size was 4 m × 3 m. Total of 9 treatments were taken under consideration. The finger millet variety used for the experiment was AAU-GSG-Marua Dhan 1. Results revealed that available nitrogen in soil after harvest was found to be significantly higher under treatment T3 (255.1 kg ha-1) followed by T4 (250.9 kg ha-1). In case of phosphorus, available P2O5 in soil after harvest was found to be significantly higher under treatment T3 (28.53 kg ha-1) followed by T4 (27.02 kg ha-1) and T2 (25.16 kg ha-1). For potassium, available K2O in soil after harvest was found to be significantly higher in T3 (243.1 kg ha-1) followed by (240.6 kg ha-1) and T2 (238.6 kg ha-1). The lowest values for available N, P2O5 and K2O in soil after harvest were observed in the control treatment.
