SOCIO-ECONOMIC IMPACTS OF EUCALYPTUS IN MARGINAL LANDS OF TAMIL NADU IN SOUTH INDIA
A study was conducted to analyze the Socio economic impact of eucalyptus cultivation in Pudukkottai district of Tamil Nadu. Eucalyptus globus and Eucalyptus hybrid were the most commonly cultivated species in the district. Survey was conducted among 120 farmers cultivating eucalyptus in their land. The study was conducted in Nilayapatti, Pulvayal and Nachandhupatti villages of Pudukkottai district. The sample size includes 20 commercial cultivators and 100 conventional cultivators. Structured questionnaire was administered collect information to analyze the cost of cultivation and economic analysis of eucalyptus cultivation, people’s knowledge about environmental impacts of eucalyptus etc. Analytical tools like Cost of Cultivation, Net Present Worth (NPW) and Benefit Cost Ratio (BCR), Ordinary Least Square (OLS) and Logit Regression analysis were employed. The study concluded that eucalyptus cultivation was much suitable for marginal and barren lands. Most of the people were aware that eucalyptus cause environmental impact as it was a natural bio drainage crop and cause allelopathy effect on neighboring field plants with the release of secondary compounds but, it does not affect the mindset of the farmers to adopt eucalyptus cultivation in larger extent. Around 70 per cent of the respondents were into eucalyptus cultivation despite knowing the impacts only because of higher income, less maintenance and fast growth of the plant. From the study we obtained profitable cultivation with BCR ranging 4 to 6.
Technology assessment of Biofertilizers for rice production under sodic soils
The growing and turning of green manure crops i.e Dhaincha enriches soil organic matter vis-à-vis additional nutrients to the soil besides reclamation of sodic soils. When incorporated into the soil, these plants break down, eventually releasing important nutrients which are necessary for adequate plant growth and development. In addition to the supply of nutrients, green manuring crops can help to scavenge the leftover nutrients from the preceding crop. It also increases soil drainage and water retention capacities that help to prevent leaching losses, soil erosion, and weed problems too as these are also incorporated. The different biofertilizers (FP: Pre season fallow+ Rice cv.Atchaya, TO1: Pre rice GM + Application of CSR bio through seed treatment and soil application + Rice cv.TRY 3, TO2: Pre rice GM + Application of Arka microbial consortium through seed treatment and soil application+ Rice cv. TRY 3) were used to manage the sodic soil. Technology option 1 (Pre rice GM + Application of CSR bio through seed treatment and soil application + Rice cv. TRY 3), resulted in higher yield (30%) followed by technology option 2 (Pre rice GM + Application of Arka microbial consortium through seed treatment and soil application + Rice cv. TRY 3) and the least was recorded by farmers practice (Pre season fallow+ Rice cv.Atchaya). Apart from this TRY 3 is highly salt tolerant variety which was known to the farmers. Hence Pre rice GM + Application of CSR bio through seed treatment and soil application + Rice cv. TRY 3 will be a suitable alternative practices for getting higher yield in sodic condition. The technology will promotes growth and yield of rice in sodic soil of pH 9.3 and also protects against soil borne disease. The farmers were willing to take up the seed treatment, soil application of biofertilizer. TRY 3 is medium duration and salinity tolerant variety. This variety is resistant to leaf folder, stem borer, brown plant hopper, blast, brown spot, sheath rot and sheath blight.
Modulation of Hematological parameters of rats fed by organically and inorganically grown foods
Complementary food plays a very important role in the total growth and development of human population. Cereals and pulses were raised adopting organic and inorganic farming practices and analysed for nutritional value. The effect of this foods were studied in animal models (albino wistar rat) fed by a formulations containing cereals and pulses in laboratory for a period of 90 days. This study aimed at assessing the effect of food formulations raised by different cultivation practices in albino wistar rats under laboratory conditions and grouped as Group I- organic and Group II – inorganic. Albino wistar rats of 21 days age were grouped in two groups containing 8 rats in a group and were fed with a feeding formulations containing rice and green gram in the ratio of 7:3 for a period of 90 days. Group I is fed with rice and green gram raised by organic farming practices whereas Group II with rice and green gram raised by inorganic farming practices. At the end of the study period blood samples were collected and biochemical parameters were analysed. The result of the study showed that due to the pesticide toxicity, hemoglobin and packed cell volume was inferior in the inorganically diet fed group.
Study on effect of different salinity on growth and morphological traits of nerium cultivars (Nerium oleander L.)
Six cultivars of nerium (Single Pink, Single White, Single Red, Double Pink, Double White and Double Red) was evaluated to identify the salt tolerant cultivars on basis of growth and morphological parameters. This study was carried out in Department of Horticulture, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai. These cultivars were transplanted polybags with soils of four different salt levels includes control (S1 – 0.87 dS m-1), low saline (S2 – 3.94 dS m-1), medium saline (S3 – 5.78 dS m-1) and high saline (S4 – 7.85 dS m-1) along with 2 dS m-1 saline water (by dissolving NaCl, CaCl2 and MgCl2) was irrigated based on moisture availability. The parameter viz., plant height (84.53 cm), number of leaves per plant (1.09 Nos.), leaf area (1773.32 cm2), stem thickness (3.12 cm), number of branches (1.09 Nos.), root length (28.87 cm), root dry weight (25.59 g), internodal length (4.01 cm) and survival percentage (94.33 %) was recorded. All parameters show significant decrease with increasing salinity. In cultivar Single Red plant height was high and low height was observed in Double Pink at high salinity. Double Red cultivar shows more tolerance to all salinity levels, but Double pink have more salinity symptoms and shows less tolerance.
A SHORT-TERM FORECAST OF GOLD PRICE AND RELATIONSHIP BETWEEN GOLD PRICE AND OIL PRICE IN INDIA
At various points throughout the history, gold has proved time and acted as a hedge against financial downturn and emerged as an important investment tool. The purpose of this study was to do a short-term forecast of gold price future trend using Auto-regressive Integrated Moving Average (ARIMA) model. Further, Vector Error Correction Model (VECM) was employed to find the correlation between gold and crude oil prices. Among various results obtained from the study, results showed that ARIMA (1,1,1) was the best fit model to predict the future price of gold. VECM analysis suggested that gold prices have long-term correlation with crude oil prices in India.
