INFLUENCE OF NITROGEN LEVELS THROUGH BRIQUETTE AND LEVELS OF SILICA ON PADDY

Nitrogen is the major nutrient plays a key role in the production of rice crop and the lateritic soils are low in available nitrogen content. Accordingly, the field study was carried out in lateritic soils of Konkan ( Coastal ) region during year (2017 – 2018) to find out the effect of different levels of nitrogen along with silica levels on growth and yield of rice. The major aspect behind taking this kind of research was to see the interaction between the applications of varying levels of nitrogen with the different levels of silica. An experiment was carried out with FRBD design. The nitrogen was given by the Konkan Annapurna Briquettes (KAB) which is the compressed tablet type mixture of the fertilizer which is having major nutrients N, P and K. Silica was applied solely through potassium silicate with the paper packets. There might have been positive response with growth and silica levels also with the rate of application of nitrogen with the increased levels of silica. It was observed that the application of 80 per cent RDN through Konkan Annapurna Briquettes (KAB) with Silica @ 100 kg ha -1 which was applied between four hills was found promising in enhancing the growth and yield of Ratnagiri-24 Cv. in lateritic during Kharif season. It could be concluded that, the application of nutrients in the form of Konkan Annapurna Briquettes along with the application of silica can reduce the recommended dose of fertilizer to the extent of 20 per cent during Kharif season in Konkan region.
