Aim: Integration of land resource inventory with land suitability to derive optimal land use at farm level.

Study Design: Land resource inventory for farm level planning using transect approach for soil profile studies and then classified soils as per USDA soil taxonomy. The soil series information was used to derive soil map and used GIS to derive crop suitability maps.

Place and Duration of Study: Mormanchi microwatershed in Gulburga tehsil.

Methodology: Detailed soil survey at 1:10000 scale using remote sensing data sets and cadastral maps with transect method of soil profile studies. Identification of soil series and defining soil phases as mapping units to derive soil map for land evaluation for sorghum and pigeon pea using GIS.

Results: The land resource information obtained from detailed soil survey shows that this micro watershed has six soil series belongs to the subgroups of vertisols and vertic integrades having low available sulphur and boron with wide spread phosphorus and Zn deficiency. The soil map with fifteen mapping units was used in land evaluation for sorghum and pigeon pea. The results showed that 35% of total area is evaluated as suitable with limitations of soil depth, gravelliness and slope. To enhance productivity, it is suggested to go for early sowing of pigeon pea with supplementary irrigation in times of dry spells but for sorghum, soil-water conservation measures must be integrated with nutrient management.

Conclusion: The fifteen shrink-swell soil mapping units in Mormanchi Microwatershed were evaluated for sorghum and pigeon pea in northern dry zone having short length of growing period. The results showed that 35% of area is suitable as against the current land use of 85% of total cultivated area.

The basic premises of this study is to analyze climate change impacts on flow rate in Ngerengere sub-basin using the data-driven model. Stream flows of sub-basin were simulated by skilled GCMs using data-driven model and Polynomial regression model. The model was setup using observed downstream flows and rainfall data. A total of 5 GCMs from CMIP5 database named as Nor ESM1-M, GFDL-ESM, Had GEM2-ES, IPSL-CM5A-LR and MIROC-ESM-CHEM were incorporated in the model. Since runoff is greatly sensitive to precipitation in comparison to other variables such as temperature, precipitation chosen as climate changing variable for projection.GCMs used in analysis and simulation of climate change impact at Ngerengere sub basin with highest skill score is 92% NorESM1-M and lowest skill score of 90%  IPSL-CM5A which are above threshold value 80%.  GCMs projected (2010 – 2049) at Sub basin decrease in average precipitation January to November while August is projected to suffer more average decrease in precipitation. unsimillar projection in average precipitation occour in  February, March, September and December. General Circulation Models projection (2010 – 2049) of stream flow in Ngerengere sub-basin is highly dependent upon the projected changes in precipitation because the patterns drawn by the precipiation changes are similar with those of stream flows. The projected (2010 – 2049) average annual decrease in stream flow of Ngerengere sub-basin is estimated to be around 18% taken as the average of the outputs of all 5 GCMs.

The study was conducted in kurukshetra district of Haryana to assess the extent of knowledge and adoption level of farm women for improved animal husbandry practices. Four villages were selected at random from randomly selected two blocks of kurukshetra district and finally 160 respondents selected purposively for the study. Thirty five practices of improved animal husbandry were subdivided into seven major aspects of animal husbandry viz., housing, feeding, pregnant & calf management, breeding management, health management, milking management and marketing. Semi structured interview schedule was used to collect the data, using personal interview. Majority of the respondents had higher knowledge about breeding management with mean knowledge score (4.88) followed by milking management (4.71), health management (4.66), pregnant animal and calf management (4.13) and housing (3.51). Medium level of knowledge of women was found in case of feeding (3.0). The poor knowledge of respondents among all the practices was found about marketing (1.54). In case of adoption the higher adoption mean score was found in health management (4.79) followed by breeding management (4.66), milking management (4.24), pregnant animal and calf management (4.12). Medium level of adoption was reported in case of feeding and low adoption in marketing practices. The age of the respondents was positively correlated with women knowledge in animal husbandry while age and farm assets were negatively correlated with adoption of animal husbandry practices by women.

Effect of blanching time in hot water (0, 5, 10 and 15 min) was carried out on six green leafy vegetables popularly consumed in Nigeria namely; Cnidoscolus asconitifoliusTalinum triangularCelosia argenteaAmaranthus hybridusVernomia anygdalina, and Telfaria occidentalis. The dry matter, total phenolic content, antioxidant activity and mineral content of the green leafy vegetables were analyzed. Blanching at temperature of 90°C and different times decreased the dry matter content of the vegetables; 5 min blanching significantly (p > 0.05) increased the total phenolic (280.6 – 980.6 mgGAE/100 g db) and antioxidant activity (25.1 – 95.1 mg/100 g Trolox equivalent) in all the vegetables. However, further increase in the blanching time caused a significant reduction in total phenolic content, antioxidant activities and mineral content of all the vegetables. With these results, it could be concluded that blanching time for these vegetables should range between 1 to 5 min to prevent the loss of health benefiting compound present in them.

Antimony, cadmium and zirconium hexacyanoferrates (II) were synthesized and characterized by elemental and spectral studies.  Interaction of 2, 4-dinitrophenol (2, 4-DNP) and 2, 4, 6-trinitrophenol (2, 4, 6-TNP) with antimony, cadmium and zirconium hexacyanoferrates (II) have been studied at neutral pH (7.00 ± 0.01) and a temperature of 30 ± 1°C. The progress of adsorption was followed spectrophotometrically by measuring the absorbance of substituted phenols at their corresponding λmax. The nature of adsorption has been interpreted from the shape of adsorption isotherms.  The Langmuir type of adsorption is followed in the concentration range of 10-3 – 10-4 M of 2, 4-DNP and 2, 4, 6-TNP solutions. The 2, 4, 6 -TNP was found to have greater affinity for the antimony, cadmium and zirconium hexacyanoferrates (II) than 2, 4 – DNP. High adsorption capacity has been observed for cadmium hexacyanoferrate (II) while it is minimum with zirconium hexacyanoferrate (II), which indicate highly porous characteristics of cadmium hexacyanoferrate (II) in comparison to other metal hexacyanoferrates (II) studied. Removal of toxic phenol is necessary for the protection of our environment. Phenols react with soil to reduce their fertility therefore its removal from soil is also important for our food security.

DOI: 10.9734/CJAST/2017/37865

Introduction: A stealthier form of deficiency is known as hidden hunger which is caused due to the intake of cheap food and having the characteristic of fulfilness but actually lacked in essential vitamins and minerals. In underdeveloped and developing countries, over 900 million poor people are at a higher risk of hunger, suffered from food insecurity and more than 1 million children died every year.

Aims: To review and study the role of biofortified cereal crops to overcome malnutrition and in food and nutrition security.

Methodology: Agriculture is the key to achievement of self-sufficiency of food grains, but now a days, biofortification becomes a sustainable approach and food based solution to overcome malnutrition even at a low cost. Different research studies and various reports were reviewed to assess the role of biofortified cereal in reducing the risk of malnutrition.

Results: Biofortification is defined as the method of breeding crops to increase and improve nutrient contents of foods including micronutrients and their precursors. Quality protein maize has double the amount of lysine and tryptophan as well as protein bioavailability that rivals milk casein. Biofortified cereals can be used for various purposes such as bakery and convenience foods, emergency ration, health food mixes, infant, snack, specialty and traditional foods and to improve the status of food and nutritional security. Prepared value added products results in an increase in food availability, add the variety to foods to make them enrich in essential micronutrients and make them affordable by reducing the price which will help to get rid of poverty as well as hunger.

Conclusion: Biofortified cereals also play an important role in contributing to the country’s food and nutritional security specifically to the poor population.
