“…The highest grain protein content (7.49%) was found in USG 2.7 g + PM 5 t ha -1 , which was statistically identical with the application of USG 2.7 g + PM 2.5 t ha -1 , USG Sarkar et al (2014) reported similar increasing trend of grain protein content of aromatic fine rice in Aman season. The percentage of grain protein increased with the increase of nitrogen rates was reported elsewhere (Ray et al, 2015, Chandel et al 2010and Mannan et al, 2009). …”

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from December 2013 to May 2014 to evaluate the integrated use of poultry manure with prilled urea and USG for improving the growth, yield and protein content of aromatic Boro rice (cv. BRRI dhan50). The experiment was laid out in a randomized complete block design with three replications. The experiment comprised 14 treatments viz. control (no manure and no fertilizer), recommended dose of prilled urea (115 kg N ha-1), urea super granules (USG) 1.8 g (55 kg N ha-1), USG 2.7 g (80 kg N ha-1), poultry manure (PM) 2.5 t ha-1, PM 5 t ha-1, recommended dose of prilled urea + PM 2.5t ha-1, recommended dose of prilled urea + PM 5 t ha-1, 50% of recommended dose of prilled urea + PM 2.5 t ha-1, 50% of recommended dose of prilled urea + PM 5 t ha-1, USG 1.8 g + PM 2.5 t ha-1, USG 1.8 g + PM 5 t ha-1, USG 2.7 g + PM 2.5 t ha-1and USG 2.7 g + PM 5 t ha-1. The experiment was laid out in a randomized complete block design with three replications. Morphological characteristics, yield contributing characters and yield of aromatic Boro rice (cv. BRRI dhan50) were significantly influenced by integrated use of poultry manure with prilled urea and USG. USG 2.7 g + PM 5 t ha-1 gave the highest plant height, number of tillers hill-1 and total dry matter production at all sampling dates while their corresponding lowest values were recorded in control. The highest yield contributing characters viz. number of effective tillers hill-1 (13.08), grains panicle-1 (124.26g) and 1000-grain weight (21.41g) were recorded in USG 2.7 g + PM 5 t ha-1 and the lowest values were recorded in control. The highest grain yield (5.33 t ha-1) and protein content (7.49%) were obtained at USG 2.7 g + PM 5 t ha-1 which was as good as recommended dose of prilled urea (115 kg N ha-1) + PM 5 t ha-1, USG 2.7 g + PM 2.5 t ha-1, USG 1.8 g + PM 5 t ha-1, recommended dose of prilled urea (115 kg N ha-1) + PM 2.5 t ha-1 while the lowest one (2.00 t ha-1) was obtained in control plots. The integrated use of poultry manure (5 t ha-1) with USG 1.8 g (55 kg N ha-1) appeared as the promising practice because of reducing considerable amount of prilled urea or USG in aromatic Boro rice (cv. BRRI dhan50) cultivation in terms of grain yield and grain protein content.Progressive Agriculture 27 (2): 86-93, 2016

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during December 2014 to May 2015 to study the effect of integrated fertilizer and weed management on the yield and gain protein content of aromatic Boro rice (cv. BRRI dhan50). The experiment comprised six sets of fertilizer managements. 1. Negative control having no fertilizers and no manures, 2. Recommended dose of inorganic fertilizers (i.e. Urea, TSP, MoP, Gypsum, ZnSO4 @ 250, 120, 120, 100, 10 kg ha -1 , respectively), 3. 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha -1 , 4. 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha -1 , 5. 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha -1 , 6. 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha -1 . Four weed managements 1. Control (no weeding), pre-emergence herbicide, 2. Panida 33 EC + one hand weeding at 35 DAT, 3. Post-emergence herbicide, Granite 240 SC + one hand weeding at 35 DAT and 4. Pre-emergence herbicide, Panida 33 EC + post-emergence herbicide, Granite 240 SC. The highest grain yield (6.40 t ha -1 ), grain protein content (7.79%) and benefit cost ratio (2.20) were obtained from 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha -1 with pre-emergence herbicide, Panida 33 EC @ 2.5 l ha -1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha -1 while their corresponding lowest values were found in weedy check without fertilization. Weed infestation reduced 58.28% grain yield in control plots due to crop-weed competition compared to plot receiving pre-emergence herbicide + post-emergence herbicide. It can be concluded that 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha -1 combined with pre-emergence herbicide, Panida 33 EC @ 2.5 l ha -1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha -1 may be used to obtain the highest grain yield and grain protein content of aromatic Boro rice (cv. BRRI dhan50).

“…Furthermore, as stated by Munkholm et al [2002], under some conditions, fertilizers may also decrease SOC concentration. In the long-term, inorganic fertilization alone proved unable to increase SOC concentration [Triberti et al 2008, Chandel et al 2010]. In our case, the SOC in N0, N40, N80, N160 and N240 were 12.4, 13.5, 16.3, 12.2 and 12.1 g kg -1 respectively.…”

Mineral N fertilizer application may have an effect on soil organic matter and other soil parameters. Therefore, we studied the effects of different doses of N fertilization on soil organic matter and chemical properties of Haplic Luvisol in the locality of Dolná Malanta (Slovakia) during 2014-2016. Soil samples were collected from the plots exposed to the following treatments: 1. The results showed that in N80 the soil organic carbon (SOC) content increased by 32% in comparison to N0. The addition of 80 kg ha -1 of N significantly decreased the humic substances (HS) content in the soil by 16% compared to N0. The higher doses of N fertilization 80 rather than 40 kg ha -1 as well as 240 rather than 160 kg ha -1 significantly decreased humus stability. The addition of N fertilization decreased the average values of soil pH. Values of hydrolytic acidity (Ha) increased by 41% and 46% in N40 and N80, respectively than N0, but on the other hand, this one decreased by 36% and 27% in N160 and N240, respectively in comparison to N0. Positive statistically significant correlations were determined between soil pH and SOC in N40 and N80 treatments. The increase of soil pH was connected with higher humus quality in N160 and N240. Negative correlations between humic acids (HA) and sum of basic cations (SBC) and cation exchange capacity (CEC) were observed in N80 < N160 < N240 treatments. Higher values of fulvic acids corresponded with lesser CEC in N80 and N160 treatments. In N160, with increased humus quality, CEC significantly decreased. The same effect was observed in N240. In addition, in N240, we also observed that with increased HA:FA ratio SBC and base saturation significantly decreased.
