GROWTH AND YIELD OF NEW AROMATIC RICE UNDER DIFFERENT LEVELS OF PLANT SPACING AND APPLIED FERTILIZER



ABSTRACT: A field experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur to assess growth and yield of newly released aromatic rice variety (cv. BUdhan 2) under different levels of plant spacing and applied fertilizer. The variety was grown incorporating three fertilizer levels viz. recommended (57- 10-8-7-0.9 kg N-P-K-S-Zn ha-1), 50% higher (114-20-16-14-1.8 kg N-P-K-S-Zn ha-1) and 50% lower (28.5-5-4- 3.5-0.45 kg N-P-K-S-Zn ha-1) than the recommended dose with three plant spacings (20 × 25 cm, 20 × 20 cm and 20 × 15 cm) representing wider, standard and closer plant densities. Results revealed that growth parameters like plant height, leaf area index, dry matter production and crop growth rate were better under the condition of higher fertilizer level with closer plant spacing. Consequently, the highest grain yield (5.18 t ha-1) of the variety was achieved under higher dose of fertilizer at closer plant spacing.
