A study carried out to assess existing basic knowledge and perceptions of farmers on fish farming in Uttarakhand Himalayas during 2003-08 indicated prevalence of as many as 16 mythical superstitions on fish identification, features of fishponds and various attributes of fishes or fish farming among farmers adding to already existing problems of fisheries development in the region. Preference for deeper fishponds or water harvesting structures (WHS) and coldwater river fishes against farmed or warm water river fishes; ignorance on the needs of liming or fertilization in fishponds and various benefits of fishes or fish farming other than for food purpose were widely held by 81-86% respondents. Ignorance on the negative impacts of fishing in rivers using powder prepared from the woody shrub, Zanthoxylum armatum DC., locally called as timru was observed in 69% respondents and probably this helps to continue periodically organized traditional fishing festivals, known as mound or machli mela using timru powder, that destroy riverine ecosystems in the region. Importance of water management in fish farming and potential of pig rearing or use of pig dung as fertilizer in fishponds or crop fields were not recognized by 50% respondents. Overall, ignorance on various principles, recommended practices and inputs of fish farming, features of fishes and fishing in rivers were prevalent in the region. A review made on issues of prevailing superstitions provided scientific and logical explanations either in support of them or otherwise. The paper identifies possible researchable issues associated with the myths and suggests dispelling unscientific superstitions maybe through appropriate research findings, trainings and positive demonstrations by the existing advisory systems.

Biomass production and turnover of fine roots were estimated in six fruit and three forest stands that had been raised on old river bed lands in the Doon valley. Significant variations (P < 0.05) were observed among species, over seasons and distances from the stem. Nearly 80% of fine roots were confined to the 0 - 20 cm soil layer in all species investigated. Fine root biomass and turnover was high at 1 m distance from the stem in moisture sensitive fruit species (mango, litchi and kinnow mandarin) due to annual addition of manure and fertilizers. In forest stands similar trends were observed except that turnover rates varied at increased distance from the stem and ranged between 0.326 and 0.884 at 1 m distance and between 0.613 and 0.811 at 2 m distance. The contribution of fine roots towards the build-up of soil organic matter and enrichment of nutrients can lead to conducive soil environment to assist natural forest recovery on these degraded sites over a period of time. © International Society for Tropical Ecology.

Enhancing productivity of rainfed crops is vital to meet the growing population needs through effective rainwater conservation measures. A field study was conducted during 1995-2003 with rainwater conservation measures, viz., contour staggered trenches (CST), cover crop of French bean (Phaseolus vulgaris) and CST+cover crop in tea plantation on 25% land slope. Rainwater-use efficiency (RWUE) of tea was maximum in cover crop (4.34-18.09kghamm-1) followed by CST+cover crop (4.69-16.79kghamm-1), and CST (3.71-16.50kghamm-1) in comparison to the control treatment (no conservation measure). Six years average rainwater productivity of tea leaves was 1.01, 0.98, 0.94 and 0.85kgm-3 for cover crop, CST+cover crop, CST and control, respectively. Rainwater productivity was increased by 19% with cover crop and 16% with CST+cover crop over control. Mean increase in yield of tea leaves by 25-37%, was associated with reduction in runoff (29-51%) and soil loss (25-68%) due to rainwater conservation treatments. Canopy development of tea had direct relationship with yield of tea and reduction in runoff and soil loss. It was recommended to adopt cover crop along with CST for increasing rainwater productivity and socio-economic status of the small tea growers in the region. © 2010 Elsevier Ltd.
