Availability Assessment

Among the basic needs of life, food possesses ahead of everyone else as it nourishes us and able to stand which leads further activity. Tamil Nadu state is self-sufficient in food production and Nutrient availability assessment also shows the same but the consumption pattern shows inverse pattern to availability because consumption is directly related with income, education, taste and preference, cultural, ethical and etc. Food consumption patterns of rural Tamil Nadu shows that high demand of Public Distribution System (PDS) observed in earlier and gradually decreased over year. Vitamin Thiamine is coming under severe inequality category in rural areas of Tamil Nadu for both 61st and 68 rounds. Goal programming was effectively optimised the nutrient requirement with least cost and optimised to higher level of nutrient status.

A soil resource inventory was conducted at village level in the Melur block of Madurai district, Tamil Nadu to assess the micronutrients status in the soils and to prepare fertility maps depicting the extent of soil micronutrient deficiency/sufficiency using GIS and GPS techniques. Soil samples were collected at revenue village wise along with geo coordinates and analysed for available micronutrients such as Zn, Fe, Cu and Mn by adopting standard procedures. Based on the nutrient status, the soils were grouped as deficient or sufficient using the critical limits. Per cent deficiency of micronutrients in Melur block was worked out and the thematic maps showing status of different available micronutrients were generated. The results indicated that, Fe and Zn  deficiency is most prevalent in the soils of Melur block  in Madurai district to an extent of more than 35 per cent, followed by Cu (1.1%) and Mn (10%).

Algal Distribution

Saltworks are important wetlands and exposed to wide range of environmental stress and perturbations. Fluctuations of salinity, brine chemistry and nutrient status leads to variation in microalgal population. The typical saltworks Sri Sankara Allom, Puthalam was chosen for the study. The investigation was aimed to list out the microalgae and calculates their abundance. The work was done in different seasons (I, II, III and IV) of the study period (March 2009 to February 2010). The reservoir pond showed major variation among micro algal species but it was low in condenser pond. Only two micro algal species were observed in crystallizer pond. A gradual reduction in number of micro algal species was observed with an increase in salinity. With regard to crystallizer, Dunaliella was the dominant one throughout the study period.

Background: The uncertainty of groundnut productivity in the rainfed areas could be minimized by in situ conserving the soil moisture received through precipitation during the cropping period and improving the nutrient status. Methods: A field experiment was conducted at the Department of Agronomy, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai, Tamil Nadu during 2014-2015 rabi season to find out the effect of charred rice husk and other organic materials enriched with or without fertilizer nutrient on the moisture retention and nutrient supply during the deficit period of crop growth. The treatment consists of charred rice husk, biochar, lignite and farm yard manure alone and enriched with the recommended dose of nitrogen (10 kg ha-1) and phosphorus (10 kg ha-1) fertilizer and compared with the absolute control and recommended dose of fertilizer (10:10:45 kg NPK ha-1). Result: The structural morphology of organic materials was studied using Scanning Electron Microscope (SEM) showed that the particles of charred rice husk were uneven and the diameter varied from 3-4 ìm with clod and block appearance, the particles of biochar were irregular in shape, uneven sized and diameter varied from 2-3 ìm with block appearance and the lignite particles found spherical and aggregated. The chemical composition of organic manure with nutrient examined under SEM-EDAX revealed that the charred rice husk contains 64.31% carbon, 28.42% oxygen and 5.96% silica. Results of the study revealed that, application of enriched FYM at 5 t ha-1 recorded significantly higher pod yield (2190 kg ha-1). The enriched biochar and charred rice husk produced comparable pod yield of 2010 kg ha-1 and 1983 kg ha-1, respectively.
