Chilli is a very important vegetable crop and has a great demand in the processing industry and export market. Chilli crop is more responsive to fertilizer application. Application of fertilizers in excess not only causes environmental problems but also reduces nutrient use efficiency, increases the cost of production and reduces the benefit-cost ratio. Nanotechnology is a newly emerging tool for solving these problems. The investigation is on “Role of organic NPK nanofertilizers on morphological and phenological parameters of chilli (Capsicum annum L.) under different nutrient managements” was conducted at Regional Agricultural Research Station, Pillicode, Kerala Agricultural University from September, 2018 to February, 2019. The experiment consisted of nine treatments with three replications laid out in randomized block design. The treatments were T1 : Control (soil test based nutrient management) ; T2 : Organic nano NPK granules ; T3 : T1 + Organic nano NPK foliar @ 0.5 % ; T4 : T1 + NPK 19:19:19 foliar @ 0.5 % ; T5 : T2 + Organic nano NPK foliar @ 0.5 % ; T6 : T2 + NPK 19:19:19 foliar @ 0.5 % ; T7 : Organic management (KAU POP, 2009) ; T8 : Organic Management + organic nano NPK foliar @ 0.5 % and T9 : Absolute control. Organic Nano NPK granules were applied as a basal dose and also as top dressing at 30 and 60 days after transplanting (DAT) @ 0.33 g / plant. Foliar spray of organic nano NPK and NPK 19:19:19 were given at 35, 65, 80 and 95 days after transplanting. Morphological and phenological observations namely plant height (cm), leaf area (cm2) per plant, number of leaves per plant, number of branches per plant, crop duration, first harvest and 50 % flowering were recorded to be maximum in the treatment, organic nano NPK granules with NPK 19:19:19 foliar spray (T6) followed by organic nano NPK granules with organic nano NPK foliar spray (T5).
