ABSTRACT
A field experiment was conducted on lowland rainfed transplanted rice var. KJT-3 during kharif 2008 at Departmental Farm of Agril. Chemistry and Soil Science, Dapoli, Dist. Ratnagiri, revealed that fertilization of transplanted rice through fertilizer briquettes distinctly improved the efficacy of applied nutrients. The fertilizer applied as briquettes containing N, P and K with eight different formulations were compared with the conventional recommended practices of fertilization. The research result revealed clear superiority of fertilizer briquettes over recommended fertilizers under the prevailing high rainfall conditions. Grain yield of rice was significantly increased when the crop was fertilized through briquettes (PU-Suphala Briquette) as compared to the conventional method of fertilizer application. The growth parameters and yield contributing characters were significantly influenced by deep placement of briquettes of different formulations. However, at par total N, P and K uptake by rice was found due to deep placement of briquettes of different formulations in comparison with conventional method of fertilizer application i.e. RDF (100:50:50 kg NPK ha-1).
