Detection of water deficit conditions in different soils by comparative analysis of standard precipitation index and normalized difference vegetation index Sunil Kumar Medida, P. Prasuna Rani, G.V. Suneel Kumar, P.V. Geetha Sireesha, K.C. Kranthi, V. Vinusha, L. Sneha, B.S.S.S. Naik, Biswajit Pramanick, Marian Brestic, Ahmed Gaber, Akbar Hossain Heliyon, 2023 The detection of water deficit conditions in different soils of Prakasam district, Andhra Pradesh, India was assessed in consecutive two seasons of 2017-18 to 2019-20 cropping seasons using combined indicators developed from Standard Precipitation Index (SPI) and Normalized Difference Vegetation Index (NDVI). Historical rainfall data during the study period of 56 administrative units were analyzed by using R software and derived three-month SPI. The MODIS satellite data from 2007 to 2020 was downloaded out of which the first ten years' data was used as mean monthly NDVI and the remaining period data was used to derive the anomaly index for the specific month. MODIS satellite data was downloaded, using LST and NDVI, and MSI values were calculated. The NDVI anomaly was derived using MODIS data to study the onset and intensity of water deficit conditions. Results indicated that SPI values gradually increased from the start of the Kharif season, reached their maximum during the August and September months, and decreased gradually with high variation among the mandals. The NDVI anomaly values were highest in October and December the for Kharif and Rabi seasons, respectively. The correlation coefficient between NDVI anomaly and SPI reveals that 79% and 61% of the variation were observed in light and heavy textured soils. The SPI values of -0.5 and -0.75; the NDVI anomaly values of -1.0 and -1.5 and SMI values of 0.28 and 0.26 were established as the thresholds for the onset of water deficit conditions in light and heavy textured soils, respectively. Overall, results suggest that the combined use of SMI, SPI, and NDVI anomaly is capable to provide a near-real-time indicator for water deficit conditions in light and heavy texture soils. Yield reduction was higher in light-textured soils ranging from 6.1 to 34.5%. These results can further be used in devising tactics for the effective mitigation of drought.
Delineation of saline soils in coastal India using satellite remote sensing Uttam Kumar Mandal, Dibyendu Bikas Nayak, Amit Ghosh, Ajay Kumar Bhardwaj, T.D. Lama, et al. Current Science, 2023 Characterizing soil salinity at the regional scale remains challenging despite decades of effort in soil mapping.Using satellite remote sensing, an effort has been made to identify the coastal saline soils in India.The study made use of the OLI sensor of the Landsat-8 satellite.The images were downloaded from the USGS EarthExplorer website.For multi-temporal studies, absolute radiometric calibration was done to minimize the impacts of changing atmospheric conditions, solar inclination and sensor view angle.Images were categorized using unsupervised classification, while a ground survey and Google Earth data were used for ground truthing.Three indices, namely normalized difference vegetation index (NDVI), salinity index (SI), and canopy response salinity index (CRSI), were used to identify soil salinity regions.For testing the vegetation index with soil salinity, 192 georeferenced soil samples from the Indian Sundarbans were collected.A relationship was developed between NDVI, SI and square of CRSI (CRSISQR) with EC e (electrical conductivity of saturation paste extract) and EC 1 : 2 (1 : 2; soil : water).For the coastal region, soils with CRSISQR < 0.16 were considered to be influenced by salinity since the relationship between EC e and CRSISQR had a maximum R 2 (0.50).It has been estimated that India has 12.94 lakh ha of saline soil within arable lands in all the coastal districts, and Gujarat (5.28 lakh ha), West Bengal (5.08 lakh ha), and Andhra Pradesh (1.06 lakh ha) were identified as the top three-salinity affected coastal states in the country.

Mapping of active and empty aquaponds using spectral indices in coastal region of Guntur District, Andhra Pradesh, India P. Prasuna Rani, , M. Sunil Kumar, P.V. Geetha Sireesha, , and Journal of Environmental Biology, 2021 Aim: To evaluate spectral indices as tools for separation of active aquaponds filled with water and engaged in shrimp/fish production from empty aquaponds using Landsat -8 data in coastal region of Guntur district, Andhra Pradesh. Methodology: The active and empty aquaponds were demarcated with Landsat satellite (Landsat-8) Operational Land Imager’s (OLI) multispectral images using maximum likelihood classifier (MLC) algorithm and spectral indices like Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), Modified NDWI (MNDWI), Water Ratio Index (WRI) and Automated Water Extraction Index (AWEInsh) by means of thresholds. Results: The supervised classification using maximum likelyhood classifier recorded the highest active aquapond area whereas; NDWI, combination of indices and WRI resulted in lower but almost similar extents. Evaluation of confusion matrix using validation points revealed that NDWI, WRI and combination of indices resulted in all most perfect agreement with a kappa value of more than 0.9. Maximum likelihood classifier, NDVI and MNDWI could separate active ponds and empty ponds from other land uses with strong agreement, while AWEInsh could separate different land uses only with moderate agreement. Interpretation: The study indicates that spectral indices like NDWI, WRI and combination of indices are able to delineate aquaponds that were cultured for shrimp/fish and kept empty at a given time with noticeably high accuracy using satellite data for better managing of resources in coastal ecosystem.
EFFECT OF PROLINE, HUMIC ACID AND POTASSIUM NITRATE FOLIAR SPRAYS ON PHOTOSYNTHETIC PIGMENTS, IONIC RATIO AND RELATIVE WATER CONTENT UNDER SALT STRESS IN MAIZE (Zea mays L.) Anjali bhadra Vijay, P Prasuna Rani Agricultural Research Journal, 2021 A green house experiment was conducted at Agricultural College, bapatla during kharif, 2017 to study the effect of supplementation of 25 per cent extra nitrogen through maize stover or its compost along with foliar spray of humic acid/proline/KNO3 on properties of maize grown on saline soil. Plants grown in saline soil showed that nitrogen deficiency contributed to the dominance of non-essential ions in exchange complex and denitrification losses at higher soil salinity. Foliar sprays were given in the form of conc. humic acid 0.2%, Proline @50 mM L-1, KNO3 @ 10 g L-1 at 20 and 40 days after sowing. Release of nutrients from organic supplements and osmoregulatory role of foliar sprays were analyzed at critical stages of knee high, tasseling and at harvest. Nutrient content of raw maize stover and its compost were analyzed and based on nutrient content they were added to the respective pots. The experiment was conducted in CRD with thirteen treatments and three replications. Results indicated that plants which received exogenous sprays resulted in higher chlorophyll a and b, K+/Na+, Ca2+/Mg2+ ratio and relative water content which resulted in better plant performance. Favorable effect of crop residue on decreasing EC of soil could be contributed to the improvement of the soil structure and porosity, thus increasing salt leaching and reducing surface evaporation which inhibits salt accumulation in the surface layers.
Phosphorus management in groundnut under rice (Oryza sativa) groundnut (arachis hypogaea) cropping system Research on Crops, 2021 A field experiment was conducted during rabi 2016-17 and 2017-18 on sandy loam soils of the Agricultural College Farm, Bapatla to study the phosphorus management practices in groundnut (Arachis hypogaea) under rice-groundnut sequence. The present investigation was conducted to find out the residual effect of phosphorus applied to kharif rice on succeeding groundnut crop and to work out the economics of different treatments in rice-groundnut cropping system. The treatments consisted of four main plots sources of phosphorus i.e. S1 : Inorganic fertilizer phosphorus through SSP, S2: Green manuring in-situ with dhaincha @ 25 kg seed/ha, S3 : Biofertilizer (PSB) @ 750 mL/ha, S4: Green manuring in-situ with dhaincha @ 25 kg seed/ha + Biofertilizer (PSB) @ 750 mL/ha and three levels of phosphorus i.e. L1: 50 % recommended dose of P L:2 100% recommended dose of P and L3 : 150 % recommended dose of P applied to rice during kharif alloted to sub-plots and during rabi season three doses of phosphorus i.e. F1 (control) F2 (50 % RDP) and F3 (100 % RDP) applied to groundnut, alloted to sub-sub plots was laid out in split-split plot design with three replications. Results of the experiment showed that residual sources and levels of phosphorus to preceding rice crop i.e., in-situ green manuring + PSB showed superior performance in terms of (yield attributes like number of filled pods/plant (29.4), number of kernels/pod (1.94), 100 kernel weight (46 g) and yield (1970 kg/ha)) of groundnut but was at par with that of application of in-situ green manuring and, significantly superior over inorganic fertilizer through SSP and biofertilizer (PSB) alone during both the years. During rabi treatments among the dose of phosphorus 100 % RDP showed significantly higher [filled pods / plant (27.6), number of kernels/pod (1.95), 100 kernel weight (44.9 g) and yield (1781 kg/ ha)] over control and it was at par with 50 % RDP during both the years. Hence, no need to go for 100 % RDP in groundnut under rice-groundnut cropping system, 50 % RDP was sufficient realizing higher yields.
Quantitative assessment of rice crop damage post titli cyclone in Srikakulam, Andhra Pradesh using geo-spatial techniques G. G. Ponnurangam, T. D. Setiyono, A. Maunahan, S. S. Satapathy, E. Quicho, L. Gatti, G. Romuga, C. Garcia, P. Prasadini, M. S. Kumar, P. P. Rani, C. K. Kumar, K. J. R. Reddy, F. Holecz International Archives of the Photogrammetry Remote Sensing and Spatial Information Sciences ISPRS Archives, 2019 <p><strong>Abstract.</strong> Mapping the extent of damage due to natural calamities remains one of the thrust areas in monitoring resource inventory through geo-spatial techniques. The effect of the cyclone ‘Titli’ and heavy rains during first fortnight of October 2018 in Srikakulam district, Andhra Pradesh State has been demonstrated using geo-spatial technology in terms of flood inundated rice area and corresponding yield and production loss. The pre- and post-cyclone (5 and 13 October 2018) flood inundation maps were generated using Sentinel-1A and TerraSAR-X Synthetic Aperture Radar (SAR) data respectively. The pre-cyclone rice area estimates were derived from multi-temporal Sentinel-1A SAR data, while yield forecast is based on the combination of satellite observations and yield simulation using ORYZA crop growth model. An intensive ground truth data collection had been carried out for the validation of satellite-derived rice area estimation of pre-cyclone event. An accuracy assessment has been carried out for district, mandal and village level. An overall accuracy of 96% with kappa coefficient 0.92 has been achieved. With the help map flood inundation and rice area maps, mandal-wise flood affected rice area and corresponding yield loss have been estimated. The post-cyclone ground truth data had been collected for quantitative assessment of crop damaged area. An overall accuracy of the flood affected rice map was 85% with kappa coefficient 0.70. It was estimated that rice crop damage assessment with SAR data indicated 53312 ha out of 205174 ha were affected and corresponding estimated yield as well as production are 0.8 t/ha and 189160 t respectively.</p>

Physiological and biochemical responses in rice (Oryza sativa L.) to high temperature: A review N. Veronica, Y. Asoka Rani, D. Subrahmanyam, K. L. Narasimha Rao, M. Lal Ahamad, P. Prasuna Rani Research on Crops, 2016 Rice is the staple food crop and is the livelihood for most of the people across the globe. Keeping the present climate change scenario in view, there is a severe threat due to rise in temperature that can affect rice yield potential. Heat stress is one of the major abiotic stresses hampering the growth of rice. Temperature at every growth stage plays a critical role in deciding the rice yields. The major effects of heat stress in rice on its morphoagronomical parameters include reduced germination, poor seedling growth, reduction in plant height and tillering, reduction in number of pollen grains, poor anther dehiscence, increased sterility, reduced grain filling and poor grain quality that ultimately lead to yield reduction. From the physiological point of view, there is an inhibition of photosynthesis and related gas exchange traits, reduction in chlorophyll content and other pigments, reduction in chlorophyll fluorescence (Fv/Fm), reduction in cell membrane thermostability as well as an imbalance between photosynthesis and respiration. Biochemically, there is an increase in accumulation of osmoprotectants (praline and glycine betaine), increase in activity of antioxidants and increase in hormone accumulation (abscisic acid and ethylene). A complete understanding of mechanisms conferring thermotolerance and identification of genotypes possessing tolerance is the pre-requisite.
