Este estudo investigou o papel da comunidade tradicional Luzia (CL) e do assentamento rural “Banco da Terra” (BT) (Mato Grosso, Brasil) na conservação on farm de mandioca, através de censo socioeconômico, levantamento etnobotânico, identificação das variedades locais e observação participante. Na CL foi encontrado maior conhecimento etnobotânico, embora o BT tenha apresentado maior riqueza (39 BT e 30 CL) e diversidade (H’ = 3,24 BT e 3,01 CL). A baixa similaridade entre os acervos revela a complementaridade dos locais na manutenção on farm da agrobiodiversidade.

Neste estudo se estimou a diversidade genética de acessos de mandioca coletados em Chapadão do Sul – MS, por meio de nove descritores qualitativos e quatro quantitativos. Após 60 dias de germinados os acessos, os descritores propostos foram avaliados. Os dados foram submetidos às análises de agrupamento pelo método de Tocher modificado, análises de correlações de Pearson e análise das componentes principais (ACPs). As análises revelaram a existência de diversidade genética no germoplasma considerando as duas classes de dados, além de correlações positivas e negativas significativas (P<0.001). Observou-se no agrupamento de Tocher Modificado a formação de seis agrupamentos, e os acessos 1 e 15 como os mais contrastantes. O ACPs confirmou a variabilidade genética dos acessos, explicando 52,14% da variabilidade nos dois primeiros ACPs. De acordo com os resultados obtidos, é possível praticar seleção em estádios inicias do desenvolvimento da cultura com fins de pré-melhoramento, expressando-se a partir dos descritores testados a diversidade da cultura mantida em condições “on farm”. Dos métodos empregados, o de ACPs é o método mais eficiente para estudar a diversidade genética de plantas de mandioca no banco de germoplasma. Palavras-chave: Manihot esculenta. Descritores Quantitativos e Qualitativos. Agrupamento, Multivariado. On Farm.         Abstract This study estimated the genetic diversity of cassava accessions collected in Chapadão do Sul - MS, through nine qualitative and four quantitative descriptors. After 60 daysof the accessions germination, the proposed descriptors were evaluated. Data were submitted to cluster analysis by the Modified Tocher method, Pearson correlation analysis and Principal Coordinate Analysis (PCoA). The analyzes revealed the existence of genetic diversity in the germplasm considering both data classes, as well as significant positive and negative correlations (P<0.001). In the Modified Tocher grouping, six clusters were formed, with the accessions 1 and 15 as the most contrasting ones. The PCoA confirmed the genetic variability of the accessions, explaining 52.14% of the variability in the first two PCoAs. According to the results obtained, it is possible to practice selection in early stages of crop development for pre-breeding purposes, expressing from the tested descriptors the diversity of the culture maintained under  farm conditions. Of the methods employed, PCoA is the most efficient method for studying the genetic diversity of cassava plants in the germplasm bank. Keywords: Manihot Esculenta.

SummaryIn this article an on-farm monitoring approach on udder health is presented. Monitoring of udder health consists of regular collection and analysis of data and of the regular evaluation of management practices. The ultimate goal is to manage critical control points in udder health management, such as hygiene, body condition, teat ends and treatments, in such a way that results (udder health parameters) are always optimal. Mastitis, however, is a multifactorial disease, and in real life it is not possible to fully prevent all mastitis problems. Therefore udder health data are also monitored with the goal to pick up deviations before they lead to (clinical) problems. By quantifying udder health data and management, a farm is approached as a business, with much attention for efficiency, thought over processes, clear agreements and goals, and including evaluation of processes and results. The whole approach starts with setting SMART (Specific, Measurable, Acceptable, Realistic, Time-bound) goals, followed by an action plan to realize these goals.

Agritourism marries Florida’s two largest industries, tourism and agriculture, to provide an on-farm recreational experience for consumers. Although Florida trails many other states in the number of agritourism operations, the number of Florida farms offering recreational experiences more than doubled from 2007 to 2012. This new 4-page document describes building codes relevant to Florida agritourism operations. Written by Mary Beth Henry and Kathryn A. Stofer, and published by the UF/IFAS Department of Agricultural Education and Communication.https://edis.ifas.ufl.edu/wc349 A companion document, Florida’s Agritourism Laws, EDIS publication AEC623, Florida’s Agritourism Laws, http://edis.ifas.ufl.edu/wc285, discusses Florida Statutes related to definitions, liability protections, and limits to regulatory authority of local governments over bona fide agricultural operations engaged in agritourism.

Agroforests and woodlots offer Northland hill country farmers investment and diversification opportunities. Agroforests have less effect on the "whole farm" financial position than woodlots, especially where a progressive planting regime is adopted and where no further borrowing is required. Establishment and tending costs for agro-forests are lower, and returns come much sooner. The proven opportunity for continued grazing under trees established in this manner, apart from a short post-planting period, further enhances the agroforesty option. Even where there is reluctance on a farmer's part to plant trees on high fertility land, the expected financial returns from agroforests on low and medium fertility land will increase the overall long-term profitability and flexibility of the whole farming operation. Woodlots may be more appropriate on low fertility areas where weed reversion is likely. Joint ventures may be worth considering where farm finances are a limited factor. Keywords: On-farm forestry development, Northland hill country, agroforestry, woodlots, diversification, joint ventures, progressive planting regimes, grazing availability.

Following the 2007/08 drought, we experienced poor pasture production and persistence on our dairy farm in north Waikato, leading to decreased milksolids production and a greater reliance on bought-in feed. It is estimated that the cost of this to our farming operation was about $1300 per hectare per year in lost operating profit. While climate and black beetle were factors, they did not explain everything, and other factors were also involved. In the last 3 years we have changed our management strategies to better withstand dry summers, the catalyst for which was becoming the DairyNZ Pasture Improvement Focus Farm for the north Waikato. The major changes we made were to reduce stocking rate, actively manage pastures in summer to reduce over-grazing, and pay more attention to detail in our pasture renewal programme. To date the result has been a reduced need for pasture renewal, a lift in whole farm performance and increased profitability. Keywords: Focus farm, over-grazing, pasture management, pasture persistence, profitability

Focused group projects engaging owners and managers of Maori farm businesses were initiated on the East Coast of New Zealand. The objective was to improve productivity and profitability on-farm through enhanced capability building and collaboration. Five group projects were evaluated. Critical success factors of learning groups were identified. Leadership, communication, organisation and commitment were required from project participants and facilitators. Collaborative and interactive processes built the knowledge and confidence of farm managers. Building trust was critical. Participation of mentor farmers reinforced learning in the group. Social network building was also important. We conclude that interactive group projects are a powerful way of building confidence of farm managers to communicate issues and make clearer, more strategically aligned decisions and actions. Collaborative farm initiatives foster ownership of issues, develop farmer support networks and ultimately the confidence to change. Keywords: experiential learning, farmer group, trust.
