Influence of Different Crop Establishment and Irrigation Methods on Growth and Growth Indices of Rice

The increasing global demand for water in many sectors has become a universal concern. Challenge is to develop advanced production systems that allow rice production to be sustained in the face of waning water availability. With the intention to find the efficient water saving technology and establishment method, a field experiment was conducted at Zonal Agricultural Research Station, V. C. Farm, Mandya, University of Agricultural Sciences, and Bangalore during Kharif 2018. The experiment was laid out in split plot design with three main plot irrigation treatments and five sub plot rice establishment treatments. The paddy variety used was ‘MTU 1001’. Objective was to study the irrigation and establishment methods on growth of rice. The results revealed that, continuous flooding recorded significantly higher plant height (80.67 cm) at harvest. Whereas, alternate wetting and drying (AWD) recorded higher leaf area index (5.06), CGR at 30 to 60 DAS, 60 to 90 DAS and 90 DAS to harvest (1.49, 3.50 and 2.47 g m-2 day-1, respectively), NAR at 30 to 60 DAS and 60 to 90 DAS (7.19 and 4.37 mg cm-2 day-1, respectively). Among establishment methods, manual transplanting recorded higher plant height (81.82 cm), LAI (5.70), DME (55.77), AGR at 30 DAS (0.36 g day-1), CGR at 30 to 60 DAS and 60 to 90 DAS (1.73 and 3.94 g m-2 day-1, respectively) and LAD at 30 to 60 DAS, 60 to 90 DAS and 90DAS to harvest (49.50, 128.70 and 272.80, respectively). However, mechanical transplanting recorded significantly more number of tillers m-2 (765.67), NAR at 30 to 60 DAS and 60 to 90 DAS (9.96 and 4.41 mg cm-2 day-1, respectively). AWD method of irrigation in mechanical transplanting and manual transplanting are found to be better among all other methods due to the higher growth and development.

The Integrated Technology of Residual Reserves Localization and Profit Increase on Brownfields

Brown fields that are currently experiencing production decline can benefit a lot from production enhancement operations based on localization of residual reserves and geology clarification. The set of solutions includes targeted recommendations for additional well surveys followed by producers and injectors workovers, like whole wellbore or selective stimulation, polymer flow conformance, hydraulic fracturing and side tracking. As a result, previously poorly drained areas are involved in production, which increases current rates and ultimate recovery. The integrated technology of residual reserves localization and production increase includes: Primary analysis of the production history for reservoir blocks ranking by production increase potential. Advanced bottom-hole pressures and production history analysis by multiwell deconvolution for pressure maintenance system optimization and production enhancement. Advanced production logging for flow profile and production layer-by-layer allocation. Conducting pulse-code interference testing for average saturation between wells estimation. 3D reservoir dynamic model calibration on advanced tests findings. Multi-scenario development planning for the scenario with biggest NPV regarding surface infrastructure. The presented integrated technology is carried stage by stage. Based on the data analysis at the first stage (the Prime analysis) it is possible to get three types of results. The top-level assessment of the current development opportunities of the area, evaluation of current residual reserves on base of displacement sweep efficiency estimation, and evaluation of the potential production increase for various blocks of the field. Results of the second stage were obtained for the block deemed with the highest potential for production increase. Those results may reveal possible complications, and relevant workovers can be advised along with additional surveys that can further help to locate current reserves. The last stage of Prime analysis provides the most suitable choice was to perform an advanced logging and well-testing, as they include both single-well and multi-well tests. Pulse-code interference tests, multi-well retrospective tests and reservoir-oriented production logging make it possible to scan the reservoir laterally and vertically, which is especially important for multi-layered fields. The reservoir parameters obtained from the test results are used to calibrate the dynamic reservoir model. The effects of production enhancement operations are calculated from the 3D model. The set of possible activities is evaluated in terms of their financial efficiency based on the economic model of the operator company using multi-scenario approach on a specifically created digital twin of the field. The unique feature of this approach lies in an integrated usage of advanced production history analysis, advanced logging and well-testing technologies, as well as further calibration of the dynamic reservoir model based on test results and used-friendly interface for field digital twin interaction. This paper demonstrates on how to use the field tests results to calibrate the reservoir model and increase the accuracy of production forecasting by reducing the model uncertainty, with intent to increase profit of brownfields.

Collective Farm Village of Mordovia in the Post-War Period

Introduction. The article explores the state of the collective farm village of Mordovia in the post-war period, when the peasantry went through a difficult and contradictory path of development, having experienced all the consequences of state policy, which was characterized mainly by the use of repressive measures and increased taxes. At the same time, the moral encouragement of the leaders of collective farm production was used, the material and technical base of collective farms was gradually strengthened. Results and Discussion. Yield growth, livestock and productivity of public animal husbandry, the strengthening of the economy of farms largely depended on the efficiency of the work of collective farmers, state farm workers, advanced production workers, agricultural production specialists. The improvement of the material well-being and cultural level of the workers of the region, first of all, was expressed in the growth of the monetary income of collective farmers, workers and employees, in housing construction. The reduction of the agricultural tax in 1953, the increase in procurement and purchase prices for agricultural products, the decrease in retail prices for some food and industrial goods, the transition to monthly and quarterly advance payment of labor changed not only the economic situation, but also the psychological climate in the village: the social and labor activity of people increased, the migration of the rural population of Mordovia decreased. Conclusion. The progressive measures implemented after September 1953 soon exhausted themselves due to systemic reasons and contradictory subjective decisions.

Improving Snapdragon Cut Flower Production through High Tunnel Season Extension, Transplant Timing, and Cultivar Selection

The demand for locally grown, specialty cut flowers is increasing and now includes nontraditional regions for production, such as the U.S. Intermountain West. The objective of this study was to evaluate snapdragon (Antirrhinum majus L.) as a cool season, cut flower crop in northern Utah, where the high elevation and semiarid climate result in a short growing season with strong daily temperature fluctuations. High tunnel and field production methods were trialed in North Logan, UT (41.77°N, 111.81°W, 1382 m elevation) with cultivars ‘Chantilly’, ‘Potomac’, and ‘Rocket’ in 2018 and 2019. Each year, five to six transplant timings at 3-week intervals were tested, beginning in early February in high tunnels and ending in late May in an unprotected field. Stems were harvested and graded according to quality and stem length. High tunnels advanced production by 5 to 8 weeks, whereas field harvests continued beyond the high tunnel harvests by 2 to 8 weeks. High tunnels yielded 103 to 110 total stems per m2 (65% to 89% marketability), whereas field yields were 111 to 162 total stems per m2 (34% to 58% marketability). Overall, production was the greatest with March transplant timings in the high tunnels and mid-April transplant timings in the field. ‘Chantilly’ consistently bloomed the earliest on 4 and 6 May each year, ‘Potomac’ had the highest percentage of long stem lengths, and ‘Rocket’ extended marketable stem production through July in high tunnels. Selecting optimal transplant dates in the high tunnel and field based on cultivar bloom timing maximizes marketable yields and results in a harvest window lasting 4.5 months.

Design of measures to increase the competitiveness of agricultural enterprises

The functioning of enterprises is possible while ensuring the competitiveness of products produced by enterprises, this is especially true for various forms of ownership of agricultural enterprises, because it is their economic activity and, accordingly, their products is one of the most important strategic vectors of Ukraine's economy. It is extremely important to design measures that are based on a strategic approach, and in the application of which it will be possible to increase the competitiveness of agricultural products that will ensure high economic efficiency and enable them to take a leading competitive position in the long perspectives. The most effective strategies for ensuring the competitiveness of agricultural products will be the use of strategies to minimize costs, differentiation and focus. The cost of agricultural products can be reduced through the introduction of energy-saving and advanced production technologies; application of the most effective forms of organization of production and expansion of scales of production; improvement of logistics, etc. We propose to use the differentiation strategy when limiting land or material resources by offering services or goods that have no analogues in terms of consumer characteristics on the market, which can be realized through the production of products with high quality consumer characteristics than potential competitors, such as: better quality products; environmentally friendly products; products with improved taste or properties, etc. When applying the focus strategy, it is necessary to emphasize the improvement of a particular type of product or its sales channel, producing products of narrow specialization, which is aimed at a particular segment of consumers or the formation of innovative channels for its implementation. Particular attention should be paid to improving the quality of agricultural enterprises and the implementation of well-developed marketing strategies. The application of all the above measures will increase the competitiveness of agricultural products that will ensure the competitiveness of enterprises as a whole.
