Inclusive Strategy for Small and Marginal Farmers in Tapioca Production, Processing and Marketing
No full textThis study was conducted to explore the post-harvest value addition opportunities for tapioca, identify the constraints faced by small and marginal farmers in processing and to suggest a strategy. Primary data from 60 tapioca farmers of Elamadu Grama Panchayath of Kollam district, Kerala were collected through interview schedule. Expert opinion was collected from the Scientists of Kerala Agricultural University (KA U), KVK, and CTCRI etc. to screen the appropriate technology for tapioca value addition. The data obtained were analysed using percentage analysis, SWOC and COWS analysis. It was found that a number of farmers were involved in tapioca cultivation and could produce marketable surplus, but were not engaged in any post-harvest value addition activities. Indeed, farmers have expressed their willingness to start value addition jointly as a group. The technocrats opined that tapioca snacks and chips are better options for value addition at farm level. The study highlighted the need for an exclusive organisation for tapioca cultivation, marketing and processing. Initiating farmer driven producer organisations and consumer linked value chain would be a promising strategy for livelihood of small and marginal farmers of tapioca

Awareness and Utilization of Information and CommunicationTechnology (ICT) in Agriculture - Farmer’s perspective
No full textIn recent times, Information and Communication Technology (ICT) has become relevant in the Indian agricultural sector. In this age of information technology, extension can empower the farming community with agricultural knowledge through /CT for the inclusive development of agriculture. The physical distance and logistic problems are the major impediments for extension services. In this context, strengthening extension services with effective use of JCT seems indispensable. Hence a study was conducted with an objective to know the awareness and utilization of JCT among farmer users of Aksahya e-kendra in Adat Crama Panchayat of Thrissur district, Kerala. The data were collected by administering a pre-tested, structured interview schedule. · The study reveals that the awareness regarding information provided through /CT tools was medium. The utilization of computer enabled /CT tools for seeking agricultural information was not substantial. However, the information provided through /CT tools was found to be useful to farmers and they have expressed medium level of satisfaction towards its usage. Major constraints in utilization of ICTs by the respondents were difficulty in further clarification of information, lack of location specific information, lack of awareness, and high cost of technolog

Автономні вітроенергетичні системи грають ключову роль у забезпеченні екологічно чистої та сталої електроенергії віддалених районів. Однак переривчастий характер вітру та відсутність підключення до мережі створюють значні проблеми для підтримки сталої якості електроенергії. Система перетворення енергії вітру відіграє важливу роль у використанні відновлюваної енергії з джерел вітру. Робочі параметри, такі як струм ротора та статора, вихідна напруга випрямлячів і перетворювачів, а також коливання фазної напруги мережі, є вирішальними для стабільного виробництва електроенергії та інтеграції в мережу. Також важлива оптимізація вихідної потужності за допомогою аналізу посилення напруги в підвищувальних перетворювачах. Забезпечення якості електроенергії за рахунок зменшення повного гармонійного спотворення в інверторах є життєво важливим для сумісності з мережею. Мета.
