Background: Manures (FYM, vermicompost, edible oil cakes etc.) are important resources which provide nutrients that could reduce bagged fertilizer costs and improves the crop growth and performance. A well-managed manure is a valuable resource in providing nutrients for crop production. As manure dries, nutrients not only get concentrated on a weight basis, but also on a volume basis due to structural changes. Compared to fresh manure, it is easier to handle and transport because of decreased volume and weight. Hence, it is necessary to pulverize the manure when it is applied to the land. Methods: Various research works previously carried out on manure pulverizers and applicators have been considered in the study to come up with an idea of developing a tractor powered manure pulverizer cum applicator. Studies concluded the importance of manure pulverization, effect of wind, angle of repose and coefficient of friction in the designing and development of manure dispensing equipment. Result: Manure pulverizer integrated with tractor PTO along with an applicator was designed and developed. The machine consists of KAU manure pulverizer, feed chute, blower, frame and hitch, gearbox and extension shaft. Power to the gearbox was drawn from the tractor PTO. Dried manure was continuously fed through the feeding chute and rotating blade helps in pulverizing the manure until it achieves a size smaller than the sieve. The pulverized manure reaches the blower unit by means of a chute and gets discharged through the flexible pipes. Maximum field capacity was noted at a traveling speed of 3.0 km h-1. A larger application rate of 1387.1 kg ha-1 for cow dung, 1624.4 kg ha-1 for goat faecal pellets and 1618.6 kg ha-1 for neem cake was noted at an engine rpm of 2500, forward speed of 2 km h-1 with a field capacity of 0.31 ha h-1.

Fertilisation in grain corn production is an important stage that must be done properly in terms of the amount of fertiliser used to reduce wastage and ensure crop growth. A fertilising implement brand Gasprado, was calibrated and evaluated for its performance to apply urea to grain corn crops at MARDI Seberang Perai, Pulau Pinang. Calibration was conducted to set the right metering for the device's opening to drop  urea that  meets the application rate of 130kg/ha. This was done by measuring the amount of urea dropped for a particular setting and distance. The machine has four metering devices which were labelled as MD1, MD2, MD3 and MD4. Additionally, the fertiliser applicator also comes with spring tine cultivating devices. The implement was tested for fertilising 56 rows of grain corn in the distance of 62 m long. The times taken for the tractor to finish four rows per run along the 62-m distance and to turn at the headland were recorded to evaluate the performance. The implement's metering devices MD1, MD2, MD3 and MD4 were calibrated at setting scales of B-1.5, B-0, B-0 and B-0, respectively that gave the urea application rate of 133 kg/ha, which was the nearest rate to the recommendation. The average working speed of the operation was at 4.08 km/h with the theoretical field capacity to be at 1.224 ha/h. Meanwhile, the machine's effective field capacity was 0.5208 ha/h, which had a field efficiency of 42.5 % for the particular farm design. The use of machine can speed up the operation of applying fertiliser to the grain corn crop but the performance is dependent on the farm layout.

Organic fertilisers are of biological origin and the amount of nutrients they produce varies greatly. Besides providing the essential macro and micro nutrients, they also provide an array of plant growth-promoting substances. Organic agronomy is a relatively recent technique of farming in developed countries. While several studies were conducted on the impact of organic fertilisers on soil properties and crop production, further research is needed to determine comparative results between organic fertilisers. This paper aims to review some of the influences and impacts of poultry manure, cow dung, goat manure, vermicomposter and seaweed extracts. Much-needed characteristics of numerous crops were enhanced with the appropriate application of these organic fertilisers. Organic fertilizer applications influences the increase of plant heights, vegetative growth, yields and yield attributes. The application of adequate fertilisers also influences the qualitative parameters and post-harvest traits of most crops. Selecting the best organic fertilisers at an optimal application rate that could be the best source of nutrient supplement in cultivating qualitative crops, is a gap that needs to bridge. Therefore, different application rates of the above organic fertilisers were also studied.

Although clear evidence for benefits in crop production is partly missing, several natural compounds and microorganisms have been introduced to the market as biostimulants. They are supposed to enhance nutrient efficiency and availability in the rhizosphere, reduce abiotic stress, and improve crop quality parameters. Biostimulants often derive from natural compounds, such as microorganisms, algae, and plant extracts. In this study, the commercial plant extract-based biostimulant ComCat® was tested in two field experiments with maize in the communities of Banikoara and Matéri in Northern Benin and six pot experiments (four with maize and two with winter barley) at the University of Hohenheim in Germany. Maize was grown under nutrient deficiency, drought, and weed competition, and winter barley was stressed by the herbicide Luximo (cinmethylin). ComCat® was applied at half, full, and double the recommended field rate (50, 100, and 200 g ha−1) on the stressed and unstressed control plants as leaf or seed treatment. The experiments were conducted in randomized complete block designs with four replications. The above-ground biomass and yield data of one experiment in Benin were collected. The biostimulant did not promote maize and winter barley biomass production of the unstressed plants. When exposed to stress, ComCat@ resulted only in one out of eight experiments in higher barley biomass compared to the stressed treatment without ComCat® application. There was a reduced phytotoxic effect of cinmethylin after seed treatment with ComCat®. Crop response to ComCat® was independent of the application rate. Basic and applied studies are needed to investigate the response of crops to biostimulants and their mechanisms of action in the plants before they should be used in practical farming.

In this study the authors analyze the effects of e-government reforms that began in mid-90ies by confronting the promises which these reforms made to government performance in the period before and after the reforms took place. The authors use fiscal and performance indicators of the Slovenian government and courts to argue that e-government did not yield any notable effects on the state performance. Finally, the authors analyze the reasons why e-government technology cannot be regarded as sustainable and suggest a different approach towards researching how to sustainably improve governance for generations to come.

Nutrient management influences soil health and crop productivity. Sustained crop production re-quires specific nutrient management options after a certain period. The objectives of this investigation were to examine the effects of inorganic and organic fertilization on yields and soil carbon budget under rice based cropping patterns in Bangladesh. The research data and informationhave been gen-erated based on previouslypublished, unpublished sources and own concept.Omission of K or im-balanced K are more influential for reduction in grain yield up to 47% in Boro (dry) season but N was most limiting up to 35% in T. Aman (wet) season. With existing fertilizer rates for growing rice, the balances of N and K are always negative. Balanced chemical fertilizer (NPKSZn) can be an option for improving crop productivity and maintain soil quality. Net ecosystem carbon (C) balances are posi-tive when 3 t ha-1 cow dung (CD), 2 t ha-1 poultry manure (PM) and 2 t ha-1 vermicompost (VC) are used in combination with chemical fertilizers. Soil amendments with organic nutrient sources (rice straw, CD, PM, VC, legume crops) and rice based cropping patterns such as T. Aman-Mustard-Boro, Boro-Fallow-Fallow, Jute-T. Aman-Fallow, Wheat-Mungbean-T. Aman, Grass pea- T. Aus-T. Aman and Potato-Boro-T. Aman can be beneficial in improving soil C budget, soil nutrient ratio, total crop production and maintenance of environmental health that will meet SDGs goal.

SUMMARYThe choice of an appropriate cropping system is critical to maintaining or enhancing agricultural sustainability. Yield, profitability and water use efficiency are important factors for determining suitability of cropping systems in hot arid region. In a two-year field experiment (2009/10–2010/11) on loam sandy soils of Bikaner, India, the production potential, profitability and water use efficiency (WUE) of five cropping systems (groundnut–wheat, groundnut–isabgol, groundnut–chickpea, cluster bean–wheat and mung bean–wheat) each at six nutrient application rate (NAR) i.e. 0, 25, 50, 75, 100% recommended dose of N and P (NP) and 100% NP + S were evaluated. The cropping systems varied significantly in terms of productivity, profitability and WUEs. Averaged across nutrient application regimes, groundnut–wheat rotation gave 300–1620 kg ha−1 and 957–3365 kg ha−1 higher grain and biomass yields, respectively, than other cropping systems. The mean annual net returns were highest for the mung bean–wheat system, which returned 32–57% higher net return than other cropping systems. The mung bean–wheat and cluster bean–wheat systems had higher WUE in terms of yields than other cropping systems. The mung bean–wheat system recorded 35–63% higher WUE in monetary terms compared with other systems. Nutrients application improved yields, profit and WUEs of cropping systems. Averaged across years and cropping systems, the application of 100% NP improved grain yields, returns and WUE by 1.7, 3.9 and 1.6 times than no application of nutrients. The results suggest that the profitability and WUEs of crop production in this hot arid environment can be improved, compared with groundnut–wheat cropping, by substituting groundnut by mung bean and nutrients application.

Most of the heavily-quoted interviews available on feminist theatre are in serious need of updating. A current account is needed of ‘feminism and theatre’ as experienced by feminist theatre practitioners, and as perceived by feminist theatre students, critics, players and their audiences. To meet this need, NTQ plans a series of interviews with women involved in the British feminist theatre movement today, whose career paths trace developments and shifts in the feminist theory and practice of the past fifteen years. The first interview is with Gillian Hanna, who worked with the 7:84 Theatre Company and with Belt and Braces from 1971 to 1975, before co-founding the Monstrous Regiment feminist theatre group in 1975. Hanna worked exclusively within the Regiment from 1975 until 1981–82. and is one of the three original members who still actively participate in Regimental management, production, and performance, though she now works extensively outside the group as well, having acted in repertory at the Liverpool Everyman and in Newcastle, Sheffield and Derby. Recently, Hanna spent the best part of a year playing in The House of Bernardo Alba. which opened at the Lyric. Hammersmith, and ran in the West End, and in the Spring of 1989 she played in Caryl Churchill's Ice Cream at the Royal Court. Her acting credits include work in TV and film, and her interests extend to translation of playtexts from French and Italian: she translated Dario Fo's Elizabeth, and is currently on a commission to translate (and re-translate) the complete oeuvre of the one-woman plays of Franca Rame and Dario Fo. Three of the Rame/Fo plays – under the joint title A Common Woman – were recently produced at the Sheffield Crucible and at the Half Moon in London, for which performance Hanna won the 1989 Time Out ‘01 for London’ Award. Projects currently under way within the Regiment include an adaptation of a Marivaux play (The Colony), and possible plans to tour both A Common Woman and Beatrice. She is interviewed by Lizbeth Goodman, originally a New Yorker, and currently a junior member and scholar of St. John's College and a graduate researcher in the English Faculty of Cambridge University, where she is working on a doctoral thesis on feminist theatre since 1968, and a book on the politics of theatre funding.

Physiotherapy is the trending medication for curing bone-related injuries and pain. In many cases, due to sudden jerks or accidents, the patient might suffer from severe pain. Therefore, it is the miracle medication for curing patients. The aim here is to build a framework using artificial intelligence and machine learning for providing patients with a digitalized system for physiotherapy. Even though various computer-aided assessment of physiotherapy rehabilitation exist, recent approaches for computer-aided monitoring and performance lack versatility and robustness. In the authors' approach is to come up with proposition of an application which will record patient physiotherapy exercises and also provide personalized advice based on user performance for refinement of therapy. By using OpenPose Library, the system will detect angle between the joints, and depending upon the range of motion, it will guide patients in accomplishing physiotherapy at home. It will also suggest to patients different physio-exercises. With the help of OpenPose, it is possible to render patient images or real-time video.

In the emerging global economic order in which agricultural crop production is witnessing a rapid transition to agricultural commodity production, potato is appearing as an important crop, poised to sustain and diversify food production in this new millennium. Temperature and unpredictable drought are two most important factor affecting world food securities and the catalyst of the great famines of the past. Decreased precipitation could cause reduction of irrigation water availability and increase in evapo-transpiration, leading to severe crop water-stress conditions. Increasing crop productivity in unfavourable environments will require advanced technologies to complement traditional methods which are often unable to prevent yield losses due to environmental stresses. Various crop management practices such as improved nutrient application rate, mulching, raised beds and other improved technology help to raise the productivity. Conservation farming practices play important role to restore soil and enhancing soil health and play important role to combat climate change issue.
