Many agricultural soils worldwide in their natural state are deficient in phosphorous (P). As P is vital for all living beings, as P fertilizers are manufactured from non-renewable resources and as P fertilizer efficiency is generally low, we need to improve the P use efficiency and minimize P fertilizers usage to ensure the future sustainability of our cropping systems. Enhanced-efficiency fertilizers use is one of the strategies to increase P fertilizer efficiency, but there is no consensus on the effectiveness of this type of technology. The need to increase the efficiency of P fertilization and the lack of information about enhanced efficiency P fertilizer justifies studies to evaluate the performance of this kind of fertilizer. Experiments were carried out in greenhouse and field conditions to investigate the effect of P fertilizer coated with anionic polymers (Policote) on corn and soybean crop development and yield, and agronomic P use efficiency. Greenhouse experiments were conducted with corn crop, while field trials were carried out with soybean crop. Greater increases in plant growth parameters, crop yield, soil P content, and fertilizer efficiency use were observed with Policote coated fertilizer than with conventional P fertilizer. The observed changes in P use efficiency among P fertilizers increased our understanding of enhanced efficiency fertilizers. The obtained results demonstrated that Policote coated fertilizer can be used as an enhanced efficiency fertilizer. Results show that Policote coated fertilizer is a more efficient way to deliver required phosphorous to plants than conventional ones.

Abstract— Typical soils of Southwestern Buenos Aires Province were evaluated to determine quality and capability for cereal and forage production having in mind potential improvements due to amendment with organic residual from agroindustrial wastes process. Studied soils from Mollisol order were, Argiudoll and Argiustol suborder, of marginal area of Pampa Argentina. The organic matter content of those soils corresponded to weakly humic soils which shows the transition from the Pampas zone to the semi-arid zone and indicates a major limiting factor. Granulometric analyses were similar, with a sandy loam texture for the Tres Arroyos soil and a borderline sandy silt loam for the Cabildo soil. Anycase the results were below the limit that indicates salinity problems. Low availability of essential micronutrient like Copper and Molibdenum were another limiting factor of the Tres Arroyos soil, where the cultivation of winter grains, such as wheat and barley is very important for regional economy. The availability of the micronutrients Zn and Cu are strongly dependent on the soil pH; therefore, the more alkaline the conditions (such as for the Cabildo soil), as a limiting factor mainly for cereals sensitive to Cinc deficiencies like maize and sorghum. Soils from this marginal areas of the Pampas (Argentina), could be improved with respect to the factors that limit soil quality and productivity.

Accurate data are needed on threshold doses for allergenic foods. Data are also needed to demonstrate that available methods of analysis can detect and quantify allergens in foods at or around these threshold levels and that they are robust and fit for purpose. This is of major concern as no curative treatment is currently available for food allergy and accidental ingestion of the culprit food can lead to severe clinical symptoms. Elimination of the problem food ingredient from the diet reduces the risk of allergic reactions but this can lead to other issues such as deficiencies, eating disorders and growth retardation. Emergency medication is available including Antihistamines (H1 blockers), EpiPen (adrenaline-autoinjector) and Corticosteroids. This presentation describes investigations into peanut allergens and their quantitation in highly complex samples.

restoring the soil physical structure and chemical fertility, improving soil organic C and therefore, sustaining the system productivity. Nitrogen fixers and phosphate solubilizer contribute through biological fixation of nitrogen, solubilization of fixed nutrients and enhanced uptake of plant nutrients (Gupta et al., 2003). INM tries to reduce the need for chemical fertilizers by taking advantages of non-chemical sources of nutrients such as the manures, composts and bio-fertilizers (Gopalasundaram et al., 2012). Bio-fertilizers application not only increases plants growth and yield, but increase soil microbial population and activity; resulting in improved soil fertility (Ramesh et al., 2014). They include free-living bacteria which promote plant growth even in polluted soils. Azospirillum, Azotobacter, Pseudomonas, Bacillus and Thiobacillus are examples of these bacteria (Zahir et al., 2004). Niess (2002) reported that plant growth promoting bacteria reduced the toxicity of heavy metals and increased plant growth and yield. Intercropping has been in practice for centuries to sustain yield, minimize risk, utilize the lag phase, and improve productivity (Rao, 2000). It reported that physico-chemical changes in soil under pure and alley cropping with Leucaena leucocephala (after six year) and found that alley cropping more suitable than pure crop (Gangwar et al., 2004).

A field experiment was conducted at Cotton Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth , Akola during the year 2014-15 with a view to study the moisture conservation techniques and nutrient requirement for cotton variety AKH-081 which is suitable genotype recommended for High Density Planting System for Vidharbha condition of Maharashtra. The experiment was laid out in split plot design replicated thrice with twelve treatments. The plot size was 6.0 x 4.5 meters spacing at 60 x 10 cm with 1.66 lakh plants per hectare. Three moisture conservation techniques consisting flat sowing, opening of furrow at 40-60 days after sowing and sowing on Broad Bed Furrow (BBF) 3 rows marked at 60 cm along with nutrient management levels RDF (60:30:30 NPK kg ha-1) ,RDF + 2.5 kg Zn ha-1, 125 % RDF (75:37.5:37.5 NPK kg ha-1) and 125 % RDF +2.5 kg Zn ha-1. The growth parameters viz. Plant height and sympodia was significantly influenced due to different moisture conservation techniques. BBF exihibited highest Plant height, Sympodia and Dry matter over the other parameter. The plant height, sympodia and dry matter per plant was increased significantly with increased in nutrient levels with micronutrients for high density planting system of cotton. Nutrients with different levels significantly influenced the yield attributes i.e Boll weight and Seed cotton yield under high density planting system. Significantly highest Seed cotton yield of (1786 kg ha-1) and was recorded with 125 % RDF + 2.5 kg Zn ha-1 which was at par with 125 % RDF. The highest gross monetary return, net monetary returns and benefit cost ratio was recorded with 125 % RDF (75:37.5:37.5 NPK kg ha-1) + 2.5 Kg Zn ha-1 which was at par with125 % RDF (75:37.5:37.5 NPK kg ha-1) which is the need of higher plant density. The highest WUE (3.02 kghamm-1) was noticed in 125 % RDF + Zn.

Building Better Soils with Cover Crops

Shortcomings with long practiced intensive tillage such as loss of soil organic matter, decline in soil productivity, subsurface soil compaction, high fuel expenditures and increased cost of cultivation led to discovery of alternate options and embarked the idea of conservation tillage. Tillage practices that are defined by the per cent of residue cover left on the soil surface with minimized frequency or intensity of tillage operations are categorized under conservation tillage. These are aimed to reduce erosion by protecting the soil surface and thereby promoting economic and environmental benefits. Impact of conservation tillage is a function of duration and therefore long term investigations of conservation tillage serve as reliable source to study different crop, soil and cultivation parameters. Conservation tillage and problem of residue management under rice based cropping system has been much talked about. However, maize being one of the most promising crops in changing climatic conditions; was less emphasized by conservationists. Maize is an erosion permitting crop and further conventional tillage in maize based cropping system enhances soil degradation, which is followed by accelerated rate of erosion and increased loss of nutrients. Lower economic returns from maize based cropping system due to higher costs involved in tillage operations is another major issue. Intensive tillage escalates the rate of oxidation of organic matter by opening the plough layer which decreases the soil organic carbon and ultimately results into degraded soil biological health. Conventional tillage in maize based cropping systems leads to persistence of particular weed flora, poor aggregate stability, development of hard pan which also creates problem of water logging in cases of poor drainage facility under maize based systems. Therefore, tillage practices needs some modifications to arrest such deteriorations that necessitated the concepts of conservation tillage. Minimum risk of soil erosion, enhanced soil quality has been observed with conservation tillage besides showing enhanced macro and micro nutrient concentration in soil under maize based cropping system. Adoption of conservation tillage in maize based cropping system has promised to increase system productivity and maize yield by 23% in light textured soil . Higher net return by 6000-10,000 Rs/ha and 4-5% increase in energy efficiency are promised under conservation tillage. Therefore, energetic and economics of conservation tillage was significantly better than conventional tillage for maize based cropping system . Conservation tillage improves soil structure and enhances soil aggregation stability which enhances infiltration rate of soil. Soil water storage increased by about 3-12% under conservation tillage ultimately increases water productivity by 25 percent.

A field experiment was conducted at Werer, Middle Awash Valley during the dry season of the 2016-17, 2017-18 and 2018-19 to investigate the effects of mulching materials and furrow irrigation methods on onion yield and water productivity under semi-arid conditions. Split plot design with three replications, in which the irrigation methods (Conventional, Fixed and Alternate Furrow) were assigned to the main plot and the three mulching materials (no mulch, wheat straw and white plastic mulch), were to the sub-plot. Results indicate that marketable onion bulb yield and water use efficiency were affected by the main effect of furrow irrigation methods and mulching materials (p< 0.05). But the interaction of irrigation methods and mulch had no significant effect on marketable onion bulb yield and water use efficiency. The conventional furrow irrigation (10081.52kg ha-1) and wheat straw mulch (12121.63 kg ha-1) resulted in the maximum marketable bulb yield. The highest water use efficiency (3.27 kg/m3) was obtained from alternate furrow irrigation method with straw mulch. This suggests that under limited irrigation water, alternate furrow irrigation along with wheat straw mulch minimize evaporation loss; maximize water productivity and sustain onion production at Amibara and similar agro-ecology and soil type.

— Water is one of the main requirements for healthy plant growth. Most arid and semi-arid regions, however, suffer from insufficient and unreliable rainfall. The prevailing soils generally cannot absorb the amount of water which rainfalls in such a short time. Based on this and many other factors a study was carried out to determine the influence of mulch and ridge tie on moisture retention and early growth of maize, at the Kebbi State University of Science and Technology Teaching and Research Farm Jega. The results shows that on a short term basis ridge tying had the highest amount of moisture, while on the long terms basis mulch had the highest moisture content and maize plant height is also more observed in the mulched plots as compared to ridge-tie respectively with the value of 45cm-75cm, and 39cm al 54cm at 3 al 5 WAP respectively al dry matter yield also give a similar trend.

Conservation agriculture (CA) refers to a set of agricultural practices encompassing minimum mechanical soil disturbance, diversified crop rotation and permanent soil cover with crop residues to mitigate soil erosion and improve soil fertility besides soil functions. The CA aims to conserve, improve and make more efficient use of resources through CA-based technologies. It has many tangible and intangible benefits in terms of reduced cost of production, saving of time, increased yield through timely planting, improved water productivity, adaptation to climate variability, reduced disease and pest incidence through stimulation of biological diversity, reduced environmental footprints and ultimately improvements in soil health. However, weeds are a major biotic interference in CA, posing big defy towards its success unless all the principles are completely followed. Development of post-emergence herbicide and growing herbicide-tolerant crops and also the retention of crop residues as a mulch help in managing weed problems and also improve soil moisture retention. Furthermore, this practice of agriculture improves soil organic carbon content which ultimately leads to an increase in input use efficiency.

One of the important principles of Conservation Agriculture is the permanent soil cover with crop residues which enhances soil and water productivity that leads to improved agricultural productivity. The effect of crop residues on soil moisture content, relative growth rate and biomass water productivity were examined in a completely randomized design at the University of Reading, Berkshire district, England. Straw treatment was significant on moisture content and water use efficiency at (p< 0.01) respectively while there is no significant difference on mean relative growth rate and dry final biomass weights. The study concluded that soil moisture content is conserved with increased use of crop residues as soil cover. The study therefore recommended that project based research on Conservation Agriculture should be carried out by governments and NGO’s that will involve farmers; also they should provide support for the knowledge diffusion of Conservation Agriculture to local farmers since it will improve yield and productivity. Extension agents and other agencies that work with farmers should also be properly trained to be able to disseminate this technology to farmers.
