Cutting-edge remote sensing technology has a significant role for managing the natural resources as well as the any other applications about the earth observation. Crop monitoring is the one of these applications since remote sensing provides us accurate, up-to-date and cost-effective information about the crop types at the different temporal and spatial resolution. In this study, satellite data Landsat 8 for Narsinghpur district, Madhya Pradesh was classified using supervised classification. Satellite data classification accuracy was also performed and resulted in overall accuracy as 87.60%.

An experiment was carried out to study the effect of seed priming on germination behavior, reserve mobilization, solute accumulation and antioxidative enzyme activities in germinating seeds of groundnut under salinity stress. Seeds of groundnut cv.TG-51 were treated with various priming agents viz., gibberellic acid 50 ppm, hydrogen peroxide 60 mM, ascorbic acid 100 ppm, salycilic acid 25 ppm, mannitol 2.5% and sodium chloride 50 mM for 14 hours and were subjected to salinity stress (200mM NaCl). Results indicated that the primed seeds showed significant improvement in germination speed and growth of embryonic axis over the unprimed ones under salinity treatment. This might be attributed to higher water uptake ability and enhanced rate of reserve mobilization because of seed priming before germination. The priming treatments also showed enhanced accumulation of proline along with higher activities of antioxidant enzymes GPOX and CAT and alleviated levels of lipid peroxidation in the embryonic axis which might contribute to osmotic regulation and mitigation of oxidative stress under salinity stress during seed germination. Among all the priming agents, GA3 50 ppm, mannitol 2.5% and NaCl 50mM especially produced encouraging results.

In general, groundwater trends are declining throughout the world due to the continuous increase of ground water withdrawal to meet the daily needs of growing population. There is a general acceptance that the recharge of ground water in the alluvial region areas is more compared to other regions, however these concepts leads to an inaccurate estimation of ground water recharge in many alluvium regions. However, the recent investigations in the Patan block of Jabalpur district of M.P. India has indicated that, the pre-monsoon water level deepness prone to the higher recharge of ground water from the precipitation and other water resources like tanks and check dams. Similarly study also suggested that the pre-monsoon ground water level influenced higher recharge of ground water than the total annual amount of rainfall in study area. The study involved analysis of the ground water data for 16 years and mapped the changed in ground water levels between pre monsoon and post monsoon Further investigations made by analyzing the data of water level in the patan block. The ground water recharge estimation has been done by using water table fluctuation method and GlS application. The study concludes that nearly 22 percent of rainfall is either joining the ground water directly through infiltration or by different recharge attributed by various water conservation structures such as check dams, reservoirs, tanks etc. Also, the finding indicated that increase use of ground water for agriculture and the rise in agriculture area has leading ground water declination issue in study area.

In present study, thirty blackgram (Vigna mungo L. Hepper) genotypes were evaluated for thirteen economically important characters. The study showed considerable variability for these characters. Heritability in broad sense was high for all the characters studied except for primary branches/ plant and days to 50% maturity. High heritability coupled with high genetic advance as per cent mean was perceived for plant height and seed yield/ plant, specified the prevalence of additive gene action in the expression of the traits. While the remaining traits showed high to moderate heritability coupled with moderate to low genetic advance as percent of mean, suggesting prevalence of non-additive gene action in the expression of the traits, therefore may be potentially utilized in recombination breeding. Furthermore, based on them per se performance, the suitable genotypes for these traits could be isolated and utilize for blackgram improvement. The association analysis revealed that the genotypic correlation coefficients were higher than corresponding phenotypic ones for all the character combinations.

This study investigated the effects of hot water and steam blanching on carrot cubes. Blanching has great effect on the moisture content, total soluble solids and ascorbic acid retention of carrot cubes. Fresh carrots were blanched in hot water and steam at different temperatures and time. The results were compared on the basis of product quality, viz. solid loss, moisture content and ascorbic acid content. The freshly cut carrot cubes weighing 20g, were subjected to hot water and steam blanching for six levels of exposure time (30, 60, 90, 120, 150 and180 seconds). Maximum solid loss (19.39 %) was observed in case of hot water blanching at 100°C and minimum (5.090 %) in case of steam blanching at 100°C for 3 minutes. In case hot water blanching as well as steam blanching moisture content was found to decrease initially up to 90s and increase in the latter stages. Higher loss of ascorbic acid was observed during hot water blanching. Steam blanching also resulted in loss of ascorbic acid, but at lower rates. The percentage retention of ascorbic acid after 3 minutes of steam blanching at 100°C, hot water blanching at 93°C and 100°C remained found to be 79.72 %, 71.67% and 69.88 % respectively
