Farmers' Participatory Demonstration of Nitrogen Application Methods during T. Aman Season in Barisal Region of Bangladesh
Journal Title: Haya: The Saudi Journal of Life Sciences - Year 2017, Vol 2, Issue 2
Abstract
Abstract: The demonstration was carried out at the farmers’ fields of Barisal region of Bangladesh to evaluate the effectiveness of fertilizer application methods in T. Aman rice in non-saline tidal flooded soil during July to December, 2015. Twenty-five-day old seedlings of BRRI dhan52 was transplanted in randomized complete block design with three replications. The trial was conducted in five locations (Babuganj, Barisal; Nolchiti, Jhalokathi; Barisal Sadar, Barisal; Amtoli, Barguna and Kolapara, Patuakha). Deep placement of urea super granule (USG) (1.8 g size) + PKSZn from BRRI recommended dose was compared with BRRI recommended fertilizer dose and farmers’ fertilizer management. The result showed that USG treated plots produced statistically the highest grain yield and less spikelet sterility compared with BRRI recommended fertilizer dose and farmers’ practices at all locations. Also, panicles per unit area and grains per panicle were highest in USG treated plot than broadcasted urea. Thus, the results revealed that USG application is the best N source in non-saline tidal ecosystem of Barisal region in T. Aman rice. Keywords: Urea super granule, prilled urea, grain yield, T. Aman rice.
