Abstract: Effect of concentrate organic manure (wellgrow grain and wellgrow soil) and NPK improved the growth and yield of wheat Significant improvement in terms of growth parameters like plant height, tillers, dry matter production and productive tillers with application of 120 : 60 : 60 NPK + 300 kg wellgrow soil/ha and at par with application of 120 : 60 : 60 NPK + 300 kg wellgrow grain/ha, treatment receiving 100% NPK + 300 kg wellgrow soil/ha resulted maximum grain yield (4545 kg /ha) Treatment of 100% NPK + 300 kg wellgrow grain/ha maintained higher straw yield (5715 kg/ha) and test weight (4410 g) due to application of 100 % NPK along with 200 kg wellgrow soil/ha whereas it was at par with application of 75 and 100% NPK with both levels of wellgrow formulation DOI: http://dxdoiorg/103329/bjbv44i122738 Bangladesh J Bot 44 (1): 143-146, 2015 (March)

Abstract: Depletion of soil fertility is a main problem to sustain agricultural production and productivity in many countries. The use of inorganic or organic fertilizer alone has both positive and negative effects on plant growth, nutrient availa-bility and the soil. Organic fertilizer improves physical and biological activities of soil but they have comparatively low in nutrient content, so larger quantity is required for plant growth. However, inorganic fertilizer is usually immediately and fast containing all necessary nutrients that are directly accessible for plants. But continuous use of inorganic fertilizers alone causes soil organic matter: degradation, soil acidity and environmental pollution. So the integrated nutrient management system is an alternative system for the sustainable and cost-effective management of soil fertility by combined apply of inorganic with organic materials resulting in rising soil fertility and productivity without affecting environment. The objective of the present review is to assess the effect of mixing organic with inorganic fertilizer on soil fertility and productivity. The study revealed that appropriate application of organic with inorganic fertilizers increases the productivity without negative effect on yield quality and improves soil fertility than the values obtained by organic or inorganic fertilizers separately.

TL;DR: The objective of this review is to discuss the technological advances in engineering lignocellulosic biomass as an economically attractive feedstock and robust microbial platforms as a powerful biofuel producer.
Abstract: Lignocellulosic biofuel has been globally recognized as a renewable energy source with environmental benefits while minimizing the competition between food and fuel supply. Although lignocellulose is a promising renewable feedstock for the sustainable production of transportation fuels, cost-effective conversion technologies are necessary to overcome its inherent recalcitrance that impedes the widespread utilization of lignocellulosic biofuels. Owing to the limited availability of cost-effective and less recalcitrant biomass, the major challenge toward biofuel commercialization includes the biochemical and genetic modification of lignocellulose in energy crops. The development of robust microbial conversion systems capable of converting a broad spectrum of carbon sources derived from biomass feedstocks into a variety of biofuels such as bioethanol, biodiesel, and advanced drop-in biofuels is also of interest in the field of biorefinery. To date, metabolic engineering and synthetic biology have made significant advances in improving the biofuel yield in feedstocks and microbial engineering. The objective of this review is to discuss the technological advances in engineering lignocellulosic biomass as an economically attractive feedstock and robust microbial platforms as a powerful biofuel producer. Finally, integrating engineering strategies and efforts in plant and microbial engineering provides future directions of an interdisciplinary approach to facilitate the commercialization of economically feasible lignocellulosic biofuels.

Abstract: A field experiment was conducted during winter season of 2014-2015 at a farm field located in Swabi Khyber Pakhtunkhwa, Pakistan, with the main aim to evaluate the influence of different organic manures on wheat (Triticum aestivum L.) production. The experiment was laid out in a randomized complete block design (RCBD), with four replications. The treatments were: T1 (control, no manure), T2 (Cattle manure), T3 (Poultry manure), and T4 (Sheep manure). All the organic manures were applied at the rate of 10 tha. At maturity, plant height (cm), number of grains per spike, grain yield, and biological yield were recorded. Results led to the conclusion that T3 (poultry manure) gave the best results, as compared to other treatments. The values of plant height, biological yield and grain yield were 87 cm, 13.66 tha and 5.750 tha, respectively, for poultry manure treatment. Results for number of grains per spike and 1000-grain weight were found non-significant in the prevailing soil condition.

Abstract: This study was conducted to evaluate the effect of liming (CaCO3 1000 kg ha−1) and application of organic fertilizers (rotted farmyard manure 40 t ha−1) and six different combination of mineral fertilizers: NPK 15:15:15 800 kg ha−1 + KAN (calcium ammonium nitrate) 240 kg ha−1; NPK 15:15:15 400 kg ha−1 + MCB (water-soluble mineral fertilizer NPK 13:11:20 + 2MgO + microelements + humic acid) 300 kg ha−1 + KAN 125 kg ha−1; MCB 400 kg ha−1; MCB 400 kg ha−1 + KMg (water-soluble mineral fertilizer Multi KMg 13:0:43 + 2MgO) 100 kg ha−1; MCB 600 kg ha−1 + KMg 100 kg ha−1 and MCB 800 kg ha−1 + KMg 100 kg ha−1 on yield and other productivity parameters of potato (Kennebec variety). The aim of the research was to optimize the system of potato plant nutrition for maximum profitability in the future potato production on acid soils of mountainous region of Montenegro. The experiments were carried out during 2015 and 2016, on Dystric Cambisols. The results obtained suggested that in both years, the highest values for all studied parameters were measured on plots with combined application of liming, organic and mineral fertilizers. In addition, a significant influence on the increase in the number of tubers per plant, the average tuber weight and the total yield was also demonstrated in all individual trials of potato nutrition, and the interaction of organic manure and mineral fertilizer. Fertilizing with rotted farmyard manure had significantly increased potato productivity, with the effect more pronounced in treatments with liming. The highest number of tubers (6.2 and 7.2), average tuber weight (93.5 g and 101.0 g) and yield (27.6 t ha−1 in 2015 and 34.8 t ha−1 in 2016, respectively) were obtained using combinations of MCB 800 kg ha−1 + KMg 100 kg ha−1 on variants fertilized with rotted farmyard manure and liming. This research is a valuable source of information for potato growers and scientists from this region as the results have shown how fertilization is raising productivity in this environment and its importance in the future potato growing on acid soils in mountainous regions of Montenegro and Western Balkans.

Abstract: Groundwater has become increasingly degraded by NO 3 , and this degradation has been partially attributed to the use of commercial inorganic N fertilizers. Conversion from conventional fertilizer management to organic farming has been proposed as a means to reduce groundwater degradation. Matching soil inorganic N supply with crop N requirement on a temporal basis is important to achieve high yield and low water degradation. Dynamics of N mineralization from two manures and N-uptake dynamics for two crops were derived from published data, and multi year simulations were done using the ENVIRON-GRO computer model, which accounts for N and irrigation management effects on crop yield and N leaching. The temporal N-mineralization and N-uptake curves did not match well. The potential N uptake for corn (Zea mays L.) exceeded the cumulative mineralized N during a significant period that would cause reduced yield. Wheat (Triticum aestivum L.) has a low and flat N-uptake peak, so that the cumulative mineralized N met N demand by wheat during the growing season. A crop with a very high maximum N-uptake rate, such as corn, would be difficult to fertilize with only organic N to meet peak demands without excessive N in the soil before and after crop growth. In order to satisfy crop N demand, a large amount of manure, which would leave much N or subsequent leaching, must be applied. It took two or more years after conversion to organic sources of N to reach maximum yield because of carryover of unmineralized manure and accumulation of mineralized N after crop uptake which was not completely leached during the winter. High initial applications to build up the organic pool followed by reduced inputs in subsequent years would be appropriate.
