Studies on the effectiveness of applying the scheme for organic processing of grape cultivar Bastardo Magarachskiy in comparison with the traditional scheme of protection against the powdery mildew on the background of its strong progression were conducted. It was established, that the organic protection scheme is not inferior to the traditional processing scheme in its effectiveness and influence on the composition of grape berries. The biological effectiveness of the organic protection scheme in vineyards averaged 78.3%. There is no significant difference in grapes obtained in the traditional and organic processing schemes by the mass of the bunch, the concentration of sugars and titratable acids in the berry. The use of biological products in foliar treatment had such beneficial effect on the formation of the phenolic complex of berries as the increase in supply of phenolic substances and growth of phenolic maturity. The use of organic protection scheme against powdery mildew led to a decrease in the concentration of pyruvic acid in juice by 2.5 times on average, compared with the traditional one, and an increase (in comparison with the traditional and control) by 1.4 −1.6 times of the concentration of α-ketoglutaric acid. The studied treatment regimens did not affect the concentration of aldehydes.

I am a 30-year-old sharemilker on my parent's 600 cow developing farm near Blackball on the western side of the Grey Valley. Earlier this year I competed in the National Young Farmer of the Year competition and finished a close third. So what is information? There are two types of information that I use. There is data gathered from my farm to help fine tune the running of the day to day operations on the farm And directional information This is the information that arrives in papers and directs the long-term direction and plans of the farm and farming businesses. Due to the variability in weather on the Coast there is a greater need to monitor and adjust the farming system compared to an area like Canterbury. This was shown last year (2001/02) when the farm was undergoing a rapid period of development and I was under time restraints from increasing the herd size, building a new shed as well as developing the farm. The results of the time pressure was that day to day information gathering was lower resulting in per cow production falling by 11% or around $182 per cow. So what information was lacking that caused this large drop in profit. • Pasture growth rates • Cow condition • Nitrogen requirements • Paddock performance • Milk production • Pre-mating heat detection As scientists and advisers I hear you say that it is the farmer's responsibility to gather and analyse this information. You have the bigger topics to research and discover, gene marking, improving pasture species, sexing of sperm and ideas that I have not even contemplated yet. This is indeed very valuable research. Where would farming be without the invention of electric fences, artificial breeding and nitrogen research? But my problem is to take a farm with below average production to the top 10% in production with the existing technology and farming principles. I have all the technical information I need at the end of a phone. I can and do ring my consultant, fertiliser rep, vet, neighbour and due to the size and openness of New Zealand science, at present if they do not know I can ring an expert in agronomy, nutrition, soils and receive the answer that I require. I hope that this openness remains as in a time of privatisation and cost cutting it is a true advantage. I feel that for myself the next leap in information is not in the growing of grass or production of milk but in the tools to collect, store and utilise that information. This being tied to a financial benefit to the farming business is the real reason that I farm. Think of the benefits of being able to read pasture cover on a motorbike instantly downloaded, overlaying cow intake with milk production, changes in cow weight, daily soil temperature and predicted nitrogen response. Telling me low producing cows and poor producing paddocks, any potential feed deficits or surpluses. This would be a powerful information tool to use. The majority of this information is already available but until the restraints of time and cost are removed from data gathering and storage, this will not happen.

SUMMARY Myrehead has revealed the eroded remnants of activity from the Beaker period (Period A) onwards, with actual settlement evinced only from about the early first millennium be. The three houses and the cooking pits of Period B may have been constructed and used sequentially. This open settlement was probably replaced during the mid first millennium bc, possibly without a break, by a palisaded enclosure (Period C), which may have contained a ring-groove house and a four-post structure. Continued domestic activity (Period D) was suggested by a single pit outside the enclosure, dated to the late first millennium bc/early first millennium ad. The limited evidence of the economy of the settlements suggests a mixed farming system.

Participatory on-farm evaluation of improved forage crops was conducted in six mixed farming system districts of Southern Ethiopia with the objective to identify farmers preferred forage crops (legumes and grasses). Two annual forage legumes (Vigna unguiculata L. (cow pea) and Lablab purpureus (L.), two perennial legumes (Medicago sativa (L.) (alfalfa) and Desmodium intortum (Mill.) Urb. (green-leaf)), and three perennial grasses (Chloris gayana Knuth (Rhodes grass) and two Pennisetum purpureum Schumach (elephant grass) accessions (No.16800 and 16798)) were evaluated in the study. The major farmers’ criteria considered in the evaluation of forage species were vegetative growth, herbage yield, tillering, protection of soil erosion, palatability, perfor- mance under dry weather conditions, performance in marginal area under low input management, multipurpose use (conservation and soil fertility) and fast growing condition. The study showed that elephant grass accession No. 16798, 16800 and Chloris gayana adapted well and farmers preferred them for their higher herbage yield, vegetative growth, tillering ability and drought resistance. Even though the annual forage legumes Lablab purpureus and Vigna unguiculata were superior in their forage yield, the farmers preferred the perennial forage legumes (Desmodium intortum and Medicago sativa) mainly for their performance under dry weather condi- tion due to their longer growth period. Therefore, the consideration of farmers’ preference for forage crops is crucial for increased adoption of improved forage crops in the region.

Introduction of organic rice-based rice cultivation technology package through demplot is done in Subak Sungi 1 using ciherang variety. The number of farmers participating in demonstration plots in organic cultivation of paddy-based rice cultivation were 5 people, with age of farmers aged greater than 55 years occupying the highest percentage (45.45%), with elementary education level (72.75%), followed by high school education (18.25%), and junior high (9%). The average farmland area is 34.63 acres, with self-owned status (55,94%), status as penyakap 41,18% and rent status 2,88%. The farmers' response to the organic rice-based rice planting assessment is quite high, as evidenced by the evaluation that 100% of farmers participating in demonstration plots know and understand about organic rice system cultivation, and they agree to develop this cultivation system in the future. Demplot research results can increase the yield components and weight of dry grain harvest per hectare. Organic rice-based rice cultivation technology EVAGRO able to increase production of dry grain harvest significantly with a value of 6.8 tons / ha. There is a tendency of dry weight value of ciherang varieties of 6.8 tons / ha giving highest but not significantly different with PGPR organic based technology.

The study has made an attempt on resource use and economic efficiency of cucumber production under poly-house farming and open field farming. Primary data collected by using purposive sampling technique from selected districts. Sample of 50 farmers (25 Poly-house farmers and 25 Open field farmers) was taken from each district on the basis of availability. Secondary data was collected from Horticulture Department. For data analysis statistical tools average, percentage and Linear Cobb-Douglas Production Function was used. The study found that the yield of cucumber was more under poly-house farming as compare to open field farming system. The reason behind this was long harvesting period and more number of fruits per plant under poly-house farming conditions. The data specifies higher net returns per acre of cucumber under poly-house farming over open field farming, which implicit poly-house farming not only highly profitable but also economically viable as compared to open field farming in study area.
