Abstract
An investigation was carried out at the Experimental Farm, Department of Horticulture, A.A.U., Jorhat during 2021-2022 to study the effect of nano-DAP on quality and soil characteristics of cabbage. The experiment was laid out in Randomised Block Design with thirteen treatments and three replications. The quality and soil characters showed significant differences among the treatments. The maximum compact heads (39.84) were obtained in T3 and among nano-DAP treatments (29.88) in T7. Observations recorded at harvesting stage showed highest number of wrapper and non-wrapper leaves at T12 (16.80) and T3 (31.93). Leaf chlorophyll content was maximum in T11 (1.36 mg/g fw), T5 (1.65 mg/g fw) and T7 (1.66 mg/g fw) at 30, 60 DAT & at harvest. N content in leaves was highest in T10 (3.62%), T3 attained the maximum P (0.46%) and K (3.95%). The maximum available NPK in soil was obtained in T9 (291.03 kg/ha), T13 (20.88 kg/ha) and T4 (95.04 kg/ha). Thus nano-DAP can be a good economic and eco-friendly alternative to conventional inorganic fertilizers, reducing the quantity of application while sustaining the quality of the produce.
