“…Our results are consistent with those reported by others for digestates (Terhoeven-Urselmans et al, 2009;Garfí et al, 2011;Barbosa et al, 2014;Bachmann et al, 2014;Frøseth et al, 2014) and for CM and SS (Chiyoka et al, 2014). In addition, the higher forage yields in response to ADM than CM and SS application reflected greater available N and P concentrations in ADM (Table 3), in agreement with results reported by others (Tambone et al, 2010).…”

“…Higher biomass yields with digestate application than unamended soils has been reported for corn (Zea mays L.; Barbosa et al, 2014), spring barley (Hordeum vulgare L.; TerhoevenUrselmans et al, 2009), potato (Solanum tuberosum L.), and two forage crops (Garfí et al, 2011). Application of anaerobically digested materials increased soil NO 3 -N concentration by about 30 to 40% compared with raw cattle slurry ( Johansen et al, 2013).…”

As biogas production expands, digestates from that industry are increasingly available as potential nutrient sources for crop production, but their agronomic value is poorly understood. Thus, a 5-yr field experiment was conducted to determine the agronomic values of anaerobically digested solid beef cattle feedlot manure (ADM) and the separated solids (SS) from ADM under a semiarid reduced-tillage dryland barley (Hordeum vulgare L.) forage cropping system. Three organic amendments, ADM, SS, and undigested solid beef cattle feedlot manure (CM), were applied annually at 200 or 400 kg total N ha −1 for 4 yr, while the residual effect was examined in the fifth year. The higher N and P availability in ADM translated into greater barley forage yields, total N uptake, amendment-derived N uptake, and apparent N recovery (ANR) from ADM-amended soil than SS-and CM-amended soils, while there were no significant differences between soils receiving SS or CM. The ANR was 22% for ADM but only 12% for CM and 9% for SS. In contrast, P uptake, the fraction of amendment-derived P uptake, and apparent P recovery were similar among all amendments. Similar yields, ANR, post-harvest soil NH 4 , NO 3 , and Olsen-P concentrations between SS-and CM-amended soils suggest that they have a comparable agronomic value. Less residual Olsen-P in soil receiving ADM than SS or CM suggests that ADM is a lower risk for P accumulation when applied at N-based rates. We recommend that current agronomic values for cattle feedlot manure could be applied to SS but not ADM.

“…Biogas slurry increases agricultural production because of its high content of plant nutrients, growth hormones and enzymes (CMS/FAO, 1996). Garfi et al (2011) asserted that the 472 SHAHEB AND NAZRUL potato yield was increased by 27.5 percent with bioslurry compared to the control. Warnars (2012) alluded that bio-slurry increased crop revenues with an average of 25 percent.…”

An experiment was conducted in farmer's field with the aim to evaluate the effect of integrated use of bioslurry and inorganic fertilizer on the agroeconomic performance of transplanted aus rice (t. aus) (cv. BRRIdhan42) in AEZ 20. The trial was laid out in a randomized complete block design with three replications. There were three treatments viz., T1: soil test based inorganic fertilizer dose for high yield goal (HYG), T2: cowdung (CD) slurry @ 5 t ha -1 with integrated plant nutrition system (IPNS) basis inorganic fertilizer dose for HYG and T3: Farmer's practice (average of 20 farmers fertilizer dose). The highest mean grain yield (3.93 t ha -1 ) of t. aus rice was obtained from the treatment T2 followed by T1 (3.46 t ha -1 ). Gross return, gross margin and benefit cost ratio were also observed higher in T2. Therefore, fertilizer package NPKSZn @ 56-4-20-9-1 kg ha -1 + cow dung slurry @ 5 t ha -1 in IPNS approach might be helpful for getting higher grain yield of t. aus rice and maintaining sustainable soil health as well.

Soil fertility in Bangladesh is gradually diminishing and this is now becoming a critical issue. Biogas slurry is a renewable energy produced organic fertilizer can be applied for maintaining the fertility of soil. In this study, a two years experiment was conducted in the year 2011 and 2012 at the farmer's field of Moulvibazar district under the agroecological zone 20 (AZE-20). The overall objective of the study was to observe the effect of bio-slurry on the agroeconomic performance of boro rice cultivation at on-farm condition. Three fertilizer treatments viz., T1: Soil test based (STB) inorganic fertilizer for high yield goal (HYG), T2: Integrated Plant Nutrient System (IPNS) based inorganic fertilizer + cowdung bio-slurry 5 tha -1 for HYG and T3: Farmer's practice as control i.e. average of 20 farmers fertilizer application dose in boro rice were considered during experimentation. Results revealed that bioslurry based boro rice production is more profitable than chemical fertilizer. The highest grain yield (5.06 t ha -1 ) was recorded from IPNS with 5 t ha -1 cow dung slurry for HYG (T2) while the lowest yield was obtained from farmer's practice. However, yield increase due to application of 5 t ha -1 Cowdung slurry slurry with IPNS based inorganic fertilizer was 115 and 124% compared to STB inorganic fertilizer and farmers followed treatment. Gross margin (Tk.65900 ha -1 ), benefit cost ratio (2.59) and marginal rate of return (451) were also obtained higher in the same treatment. Thus, nutrient package NPKSZn @102-12-25-18-2 kg + cowdung slurry 5 tha -1 might be helpful to get increased yield and improve soil health in AZE-20.
