Effects of multi-time scales climate changes on tobaccoplanting counties in Chenzhou city of Hunan Province

To provide scientific instruction in predicting the climate changes and adopting the suitable measures for field cultivation and management of tobacco, the changes of main climatic parameters on multi-time scales in the six tobacco-planting counties of Chenzhou city in China were studied. Sunshine hours (S) in the six counties had significant positive linear correlation with year (from 1980 to 2020) and precipitation (P) changed irregularly on the scales of year, field-growth period, and rooting and flourishing stages, and they changed significantly in maturing stage. Sunshine hours (S) in the six counties had significant positive linear correlation with year on the scale of rooting stage, changed irregular with year on the scale of year, and showed different change tendencies in different counties in flourishing and maturing stages. On the scale of field-growth period, the daily cumulative temperature (T) was lower than the optimal value in rooting and flourishing stages, but higher than the optimal value in maturing stage.

A Study on the Role of Precision Agriculture in Agro-Industry

Purpose: Agriculture is a vast field that necessitates the assistance of disciplines from other fields in order to properly grow. In recent days Information technology is been used in agriculture that helps in the efficiency of the growth of the productivity of agriculture such as in the development of the quality of the farming and its products Precision agriculture are used to increase the growth of the crop quantity. In this paper, a survey includes the analysis and application of precision agriculture. Precision agriculture is used to increase the growth of the crop quantity. And various Precision agriculture companies that have helped the farmer in the field growth. Objectives: To study the role of Information Technology used in Agriculture, and view on various techniques used in precision agriculture. Methodology/Design/Approach: The analysis and the application of precision agriculture are done by referring various research paper, articles. A Literature Survey is done. Findings/Result: Farmers are currently hesitant to use the new Techniques, when compared to traditional farming, Precision farming has the potential to produce higher yields. Originality/value: Based on the secondary data available, the paper focus on the application of precision agriculture. Findings/Result: To study the role of Information Technology used in Agriculture, Precision Agriculture.

Making Space for Emotions: Empathy, Contagion, and Legitimacy’s Double-Edged Sword

Legitimacy is critical to the formation and expansion of nascent fields because it lends credibility and recognizability to once overlooked actors and practices. At the same time, legitimacy can be a double-edged sword precisely because it facilitates field growth, attracting actors with discrepant practices that may lead to factionalization and undermine the coherence of the field’s collective identity. In this paper, we investigate how organizations can mitigate the downside of legitimation by eliciting emotions that align increasingly discrepant actors and celebrate an inclusive collective identity. We leverage fieldwork and computational text analysis to examine the relationship between legitimation, collective identity coherence, and emotions in the context of the Makers, a nascent field of do-it-yourself hobbyists and technology hackers. In our quantitative analysis we show that legitimation was associated with increased field heterogeneity, but that collective events countered the diluting effects of legitimation. In the qualitative analysis of our interview data we demonstrate that activities at these events—demonstrations and hands-on experiences—elicited emotional contagion and empathy among actors. These emotions reconciled tensions among increasingly heterogeneous actors and bolstered the coherence of the Maker collective identity. We conclude by discussing our contribution to research on legitimacy, collective identity, and field-configuring events.

Enhancing plant quality and outplanting growth of Acacia auriculiformis in dry wasteland plantations by inoculating a selected microbial consortium in the nursery

In this study, the performance of a selected microbial consortium (Scutellospora calospora + Azotobacter chroococcum + Bacillus coagulans + Trichoderma harzianum) on Acacia auriculiformis A. Cunn. ex Benth. was evaluated through large-scale nursery trials at three locations in the Mandya district of Karnataka state, India. At each location, 500 inoculated and 500 uninoculated seedlings were cultivated. The increase in plant dry biomass of inoculated plants was 31% (mean of three locations) compared with uninoculated plants. The seedlings inoculated with microbial consortium under large-scale nursery trials were planted in wasteland at three locations, and their growth was monitored for nearly 6 years. At the end of the study, field growth of inoculated trees, measured as the biovolume index, was 52% higher than that of uninoculated trees. This study shows that the selected microbial consortium enhances nursery quality and midterm field growth of Acacia auriculiformis plantations on dry wasteland.

Flowering and yield of eastern filbert blight resistant hazelnut cultivars in southwestern British Columbia

Trees of six recently released hazelnut (Corylus avellana) cultivars (Eta, Gamma, Jefferson, Sacajawea, Theta, and Yamhill) were grown at five locations in southwestern British Columbia to evaluate female receptivity and pollen shed timing, disease resistance, and nut yield. The overlap of female receptivity and pollen shed of mating-compatible cultivars equaled or exceeded that reported elsewhere. Following 4–6 yr of field growth without fungicides at sites adjoining eastern filbert blight (EFB)-infected orchards, EFB symptoms were absent from four cultivars (Eta, Gamma, Theta, Yamhill), negligible on Jefferson, and substantial on Sacajawea. Two additional potential diseases, Phomopsis sp. and Phytophthora sp., were observed on several trees at multiple farms. Yields varied by cultivar and farm, averaging 2.9 kg per tree of sixth-leaf Jefferson and 1.0 kg per tree of fourth-leaf Yamhill; the highest yield per tree observed was 9.3 kg for fifth-leaf Jefferson. These data, the first describing flowering and yield of these cultivars from operational orchards and the only such data from British Columbia, demonstrate the potential for new hazelnut cultivars even where pressure from eastern filbert blight is high. Also revealed are two potential emergent diseases for which growers need to remain vigilant.
