“…As a consequence, the rice plant had a constant supply of nitrogen during its growth cycle, which eventually led to a more grain yield. The aforementioned findings are in line with those of presented in [32], who found that deep insertion of USG was superior than PU and N loss was likewise negligible.…”

When growing rice, nitrogen (N) is the most vital component since it determines how much grain the crop will produce. Among the many causes of rice’s low productivity, improper nitrogen supply and inefficient nitrogen use are thought to be an important issue. In order to ensure sustainable N-management as well as to lower N-losses, it was decided to investigate how various rice cultivars react to both organic and inorganic nitrogen sources, as well as how weed infestation behavior changes with these sources in boro rice fields. Five distinct fertilizer combinations, including the control, were tested in an entirely block design that was randomized and had three replications. Each of the following sources of N: urea (prilled) at 100% of the RD (N100PU), poultry manure at 100% of the RD (N100PM), urea at 50% of the RD + poultry manure at 50% of the RD (N50PU+50PM), and urea super granule at 100% of the RD (2.7 g per 4 hills) (NUSG) were administered on BRRI dhan29, BRRI dhan88, BRRI dhan92 and BRRI dhan96, respectively. It is observed that N50PU+50PM was beneficial for weed among the nitrogen sources. But comparatively less weed invasion was noticed in the NUSG treated plots next to control specially in BRRI dhan29. With the use of NUSG, all of the varieties tested in this experimentation generated greater grain yield than they did with the use of the other nitrogen sources. When treated with NUSG, BRRI dhan29 showed a rise in grain yield around 64.34% and a greater nitrogen utilization efficiency compared to control. When benefit cost ratio (BCR) is considered, both the BCR and net income were the highest for the BRRI dhan29 variety while NUSG was employed. Finally, it can be inferred that, in comparison to other sources, the combination of BRRI dhan29 with application of NUSG appeared as the promising combination in order to increase grain production while improving nitrogen use efficiency, greatest BCR and to lessen the infestation of weeds throughout the boro season.

“…This resulted in continuous supply of available nitrogen throughout the growth period of rice plant, which ultimately gave the higher grain yield. The above results are well correlated with the findings of Sarker et al (2012) reported that deep placement of USG was more effective over PU and N loss was also minimal. They also reported that USG can save 10-20% N fertilizer instead of traditional PU fertilizer.…”

Field experiment was conducted to determine the effect of prilled urea (PU) and urea super granule (USG) with their different nitrogen levels (N1 : 70, N2 : 100 and N3 : 130% of the recommended dose) on rice and NH4+-N/NO3- -N in post-harvest soil. Experiment was laid out in a randomized completely block design with three replications at Bangladesh Institute of Nuclear Agriculture (BINA) Farm, Mymensingh, Bangladesh during 2015-16. Higher yield attributing characters (plant height, effective tiller panicle-1, panicle length were achieved from USG × N2 treatment. USG, N2 (100% N) and USG × N2 produced the highest grain (3.60, 3.64, 3.78 t ha-1) and straw yield (3.55, 3.45, 3.70 t ha-1) respectively. Though USG × N3 treatment produced the highest effective tiller, panicle length and unfilled grain but USG × N2 treatment produced maximum grain yield of rice due to higher filled grain. In respect of mineral nitrogen, NH4+-N was decreased with the increase in soil depth but opposite result was found in NO3- -N in soil. Deep placement of USG fertilizer released NH4+-N slowly and steadily compared to prilled urea in soil. As a result, one time fertilizer application of USG is better than three times broadcast application of PU in terms of crop yield, nitrogen status in different depth of soil and labour cost. Future research needs to develop the effective USG fertilizer applicator for deep placement in soil during crop production.

“…The economic analysis also showed that the use of urea super granule was economically viable to cultivate the tomato. Sarker et al (2012) showed that USG was more effective over PU, and N loss was also minimum than that of PU where 10-20% N fertilizer could be saved by using USG instead of traditional PU. They also reported that all the rate of N as USG showed better performance than that of normal PU for cabbage yield and found economically viable.…”

A field experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during 2010-2011 to determine the effects and economic performance of urea super granule (USG) and prilled urea (PU) in terms of growth and yield of broccoli and to find out the optimum and economic doses of USG and PU for broccoli in Shallow Red-Brown Terrace Soil under Madhupur Tract. The experiment was laid out in a randomized complete block design with three replications having 17 treatment combinations constituted with different levels of urea super granule (USG) and prilled urea (PU). Result showed that yield of broccoli increased significantly with increasing rate of USG and PU. The treatments containing 160 kg N from USG and 180 kg N from PU exhibited the best performance on yield and yield contributing characters of broccoli having the head yield of 12.9 and 10.6 ton ha -1 , respectively. All the yield contributing characters and the economic profitability were favorably correlated with these high yield performing treatments. The performance of USG in terms of growth, yield and yield attributes, head quality (compactness coefficient) and economic profitability was found significantly higher as compared to that of PU. Therefore, USG @ 160 kg N ha -1 and PU @ 180 kg N ha -1 along with other recommended fertilizers could be suggested for broccoli production in terms of yield and economics. From quadratic equation USG @ 163 and 160 kg N ha -1 and PU @ 169 and 160 kg N ha -1 along with other recommended fertilizers could be suggested as optimum and economic doses for broccoli production in Silty Clay Loam Soil of Madhupur Tract.
