This study was conducted to evaluate the efficacy of different organic manure and inorganic fertilizer on the yield and yield attributes of Boro Rice (Oryza sativa L.). The experiment consisted of 8 treatments, T0: Control, T1: 100% N100P15K45S20 (Recommended dose), T2: 50% NPKS + 5 t cowdung ha-1, T3: 70% NPKS + 3 t cowdung ha-1, T4: 50% NPKS + 4 t poultry manure ha-1, T5: 70% NPKS + 2.4 t poultry manure ha-1, T6: 50% NPKS + 5 t vermicompost ha-1and T7: 70% NPKS + 3 t vermicompost ha-1. At 30, 50, 70, 90 DAT and at harvest stage the tallest plant (24.18, 31.34, 44.67, 67.05 and 89.00 cm) and the greatest number of total tiller per hill (5.43, 11.64, 21.01 and 17.90) at same DAT was recorded from T5 and the lowest was observed from T0 in every aspect. The maximum number of effective tillers per hill (13.52), the longest panicle (24.59 cm), maximum number of total grain per plant (97.45), the highest weight of 1000 seeds (21.80 g), the maximum grain yield (7.30 t ha-1) and straw yield (7.64 t ha-1) was recorded from T5 treatment whereas the lowest number of effective tillers per hill (6.07) , the shortest panicle (16.45 cm) , the minimum total grain per plant (69.13) , the lowest weight of 1000 seeds (16.73 g), the lowest grain yield (2.06 t ha-1) and straw yield (4.63 t ha-1) was observed from T0 treatment. Although the highest biological yield was recorded from T5 treatment but statistically similar result were found from T3, T4 and T7 treatments. The highest harvest index also recorded for T5 treatment. It was obvious that yield of rice can be increased substantially with the judicious application of organic manure with chemical fertilizer.

A field experiment was carried out at Spices Research Centre, Shibgonj, Bogra during two consecutive years, 2013-2014 and 2014-2015 to evaluate the response of integrated nutrient management on nutrient uptake, protein content and seed yield of fenugreek (Trigonella foenum-graecum L.) var. BARI Fenugreek-2. The field experiment was conducted in combination with inorganic fertilizer and organic manure. The result showed that the treatment T7 compeises application of PM @ 4 t ha-1 + CF (IPNS) produced the maximum seed yield (2.1 t ha-1) but statistically identical to T8 (VC @ 3 t ha-1 + CF (IPNS) and T6 (CD 5 @ ha-1 + CF (IPNS). In case of stover yield, the treatment T7 produced the highest yield (4.89 t ha-1). The grain yield was increased over control and ranged between 65.85 to 156.10 %.The treatments T7 and T8 resulted in higher nutrient use efficiency along with higher N, P, K and S uptake by the plant. The application of inorganic fertilizer along with manure influenced the nutrient concentration in fenugreek seed and stover yield. The higher seed with N, P, K and S concentrations were observed in the treatments where poultry manure @ 4 t ha-1 applied in combination with chemical fertilizers. The combined application of fertilizer and organic manure increased the organic carbon (OC %), organic matter (OM %), total N, available P and available S in post harvest soils. The findings indicate that the integrated use of inorganic fertilizer and organic manure should be encouraged to improvement the deteriorating soil fertility and increased crop yield of fenugreek.SAARC J.

SUMMARYLong-term fertilization experiment has been conducted since 1981 to study the effect of soil management practices on soil fertility, soil carbon and nitrogen sequestration, soil culturable microbe counts and crop yields at the Nanhu Experimental Station in the Hubei Academy of Agricultural Sciences (situated in the middle reach of the Yangtze River and the rice–wheat cropping system). The experiment was designed with the following eight treatments: (1) unfertilized treatment: Control; (2) inorganic nitrogen fertilizer treatment: N; (3) inorganic nitrogen plus inorganic phosphorus fertilizer treatment: NP; (4) inorganic nitrogen, inorganic phosphorus plus inorganic potassium fertilizer treatment: NPK; (5) pig dung compost (manure) treatment: M; (6) inorganic nitrogen fertilizer plus manure: NM; (7) inorganic nitrogen, inorganic phosphorus fertilizer plus manure treatment: NPM and (8) inorganic nitrogen, inorganic phosphorus, inorganic potassium fertilizer plus manure treatment: NPKM. The results showed that long-term application of organic manure in combination with inorganic fertilizer significantly (p < 0.05) increased soil organic C concentrations compared with the corresponding inorganic fertilizers alone. Soil organic C contents were significantly (p < 0.05) increased in balanced application of NPK fertilizers in comparison to unbalanced application of fertilizers. After 30 years of experiment, soil organic C and total N sequestration rate averagely were 0.48 t ha−1 year−1 and 28.3 kg ha−1 year−1 in the fertilized treatments respectively; nevertheless, it were 0.27 t ha−1 year−1 and 9.7 kg ha−1 year−1 in the unfertilized treatment. Application of organic fertilizer in combination with inorganic fertilizer significantly (p < 0.05) increased culturable microbial counts compared with the corresponding inorganic fertilizers alone. The balanced application of NPK fertilizers significantly (p < 0.05) increased culturable microbial counts compared with unbalanced application of fertilizers. The average grain yield of wheat and rice was significantly (p < 0.05) higher in organic manure combined with inorganic fertilizer treatment than in inorganic fertilizer alone and unfertilized control. Therefore, long-term application of organic manure combined with inorganic fertilizer and balanced application of NPK fertilizers could increase soil organic C and total N sequestration, culturable microbial counts and crop grain yields.

Abstract The need for sustainability in food supply has led to progressive increase in soil nutrient enrichment. Fertilizer application affect both biological and abiotic processes in the soil, of which bacterial community that support viral multiplication are equally influenced. Soil viral community composition and dynamics are affected by soil fertilization with less exploration on organic and inorganic fertilizer application. In this study, we evaluated the influence of soil fertilization on the maize rhizosphere viral community growing in Luvisolic soil. The highest abundance of bacteriophages were detected in soil treated with high compost manure (Cp8), low inorganic fertilizer (N1), low compost (Cp4) and control (Cn0). Our result showed higher frequency of Myoviridae (47%), Podoviridae (46%) and Siphoviridae (90%) in high organic manure (Cp8) fertilized compared to others. While Inoviridae (98%) and Microviridae (74%) were the most abundant phage families in low organic (Cp4) fertilized soil. This demonstrate that soil fertilization with organic manure increases the abundance and diversity of viruses in the soil due to its soil conditioning effects.

Soil organic carbon (SOC) and its labile fractions are strong determinants of soil chemical, physical, and biological properties and the recycling of crop residues is an important factor affecting soil organic matter levels and soil quality. This collected review literature specifically aims on soil fertility related to aggregate associated carbon, aggregate-size distribution, aggregation and storage of soil organic carbon trends and their respond towards organic and synthetic fertilizers and also understanding of the effects of diverse soil management regimes on SOC sequestration in cereal systems. Several studies results showed that, with the exception of unfertilized control (CK) and nitrogen fertilizer (N) treatment, the concentration of SOCs in the soil layer 0-20 cm increased. The SOC concentration and storage to depths of 60 cm is significantly affected by long-term fertilization. SOC concentrations and stocks below 60 cm for all treatments were statistically insignificant. The degree of SOC was higher in farmyard manure plus N and P fertilizers (NP+FYM) at different depths, compared with CK, at 0-60 cm soil profile and followed by straw plus N and P fertilizers (NP+S) respectively. SOC storage in NP+FYM, NP+S, FYM and nitrogen and phosphorus (NP) fertilizers treatments increased by 41.3%, 32.9%, 28.1% and 17.9% respectively compared to CK treatment in 0–60 cm. Organic manure plus inorganic fertilizer application also increased organic carbon pools of the labile soil at depths of 0–60 cm. Particulate organic carbon (POC), dissolved organic carbon (DOC) and microbial biomass carbon (MBC) average concentration in organic manure plus inorganic fertilizer treatments (NP+S and NP+FYM) increased by 64.9–91.9 percent, 42.5–56.9 percent and 74.7–99.4 percent over CK treatment. The average control treatment SOC concentration was 0.54 percent, which increased to 0.65 percent in RDF treatment and 0.82 percent in RDF+FYM treatment and increased enzyme activity, potentially affecting soil nutrient dynamics in field conditions. The RDF+FYM treatment sequestered 0.28 Mg C ha-1 yr-1 compared with the control treatment while the NPK treatment sequestered 0.13 Mg C ha-1 yr-1 respectively. It can be concluded that long-term additions of organic manure have the most beneficial effects on the production of carbon pools, improve the availability of SOCs and also enhance C sequestration in soils.

A pot experiment was conducted in the net house of the Agronomy department, Sher-e-Bangla Agricultural University, Dhaka during the period from November, 2018 to March, 2019 to evaluate the suitable organic source to mitigate the drought stress impact on wheat. The experiment comprised two factors viz. factor A: Three levels of organic manures, i)  O0 = Control (Without organic manure),       ii) O1 = Cowdung (10 t/ha), iii) O2 = Poultry litter (5 t/ha), and factor B:  four levels of drought i) D0 =  Control (without drought), ii) D1 =  Crown root initiation stage (at 20-29 DAS), iii) D2 =  Booting stage (at 45-54 DAS), iv) D3 = Anthesis stage (at 55-64 DAS). The experiment was laid out in a completely randomized design (factorial) with three replications. Organic manure showed positive impact on yield and cowdung (O1) gave the highest grain yield (4.06 g plant-1). This may be attributed to the highest number of effective tillers plant-1 (3.21), spike length (9.53 cm), spikelet spike-1 (17.31), grains spikelet-1 (2.31) and 1000-grain weight (44.61 g) of wheat in this treatment. In respect of drought imposition treatments, grain yield was found higher in control treatment (without imposition of drought) which was statistically similar with drought imposition at booting stage treatment (D2). These two treatments also showed highest number of effective tillers plant-1, spikelets spike-1, grains spike-1 and 1000-grain weight. Regarding the interaction of organic manure and drought, cowdung without drought imposition (O1D0) and cowdung with drought imposition at booting stage (O1D2) were highest yielder among the other interactions which was attributed to higher 1000-seed weight, number of effective tillers plant-1, spikelets spike-1 and grains spike-1. Results revealed that application of organic manure could reduce the impact of drought on wheat irrespective of growth stages. However, application of cowdung (10 t ha-1) was found more effective to combat drought impact at booting stage of wheat compared to other growth stages. Bangladesh Agron. J. 2020, 23(2): 81-86
