Effect of Nano-DAP Application in Combination with Conventional
Fertilizers on Rice-Rapeseed Sequence under Rain-Fed Condition

Mohanpur-741252, West Bengal, India
Excessive use of DAP fertilizer in rice production of West Bengal resulted several soil and
environment hazards. The overall efficiency of applied fertilizer has also been declined, which
necessitates alternative nutrient management. Hence, attempts were being made to find out the
effect of nano-DAP as an alternative source of conventional fertilizer on growth, yield and
economics of rice-rapeseed predominant crop sequence.
Methodology
Field experiment was conducted during 2021-22 at Department of Agronomy, B.C.K.V, West
Bengal in a randomized block design with three replications where transplanted rice (cv. IET-
4786) grown in kharif season (July-October) under rain-fed condition with thirteen treatments
(Table 1) followed by rapeseed (cv. B-9) in rabi season (November-February) under ten
treatments (Table 2) in sandy clay loam with pH 6.65, organic carbon 5.8 g/kg, available N
159.2 kg/kg, available P 2O 5 44.9 kg/kg and available K 2O 101.8 kg/kg. As per treatment, nano
DAP was applied through seed treatment, seedlings root dipping and foliar spray along with
conventional DAP, urea SSP and MOP fertilizers. Rainfall in rice and rapeseed growing period
