Assessing soil moisture content (SMC) is necessary for managing water at a spatial scale. Remote sensing technologies provide robust approach detecting the spatial-temporal fluctuations of SMC. The aim this study was to estimate SMC different depths using very high-resolution unmanned aerial vehicle (UAV)-based multispectral (MS) images and machine learning algorithms generate maps best-performed (ML) algorithm. UAV-based bare were captured 40m altitude with high resolution (2.89 cm) during...

Inappropriate use of phosphorus and nitrogen fertilizers has imposed irreparable damage to plant growth productivity. Urea doped hydroxyapatite nanoparticles (Ur@HANP) was designed for controlled-release formulation crop improvement. The main objective the present work synthesize evaluate functioning Ur@HANP on rice seed germination transport nano-nutrients in soil media. HANP synthesized using sol–gel technique urea loaded into it monitoring seeds' physiological biochemical activities under...

Alternate wetting and drying irrigation practice in rice cultivation can save a significant amount of water. It involves irrigating fields alternately based on an triggering criterion possibly influences the soil–plant–water system. In this study, field experiments were carried out for 3 years with three levels soil matric potential heads (SMPHs) (no water stress: conventional irrigation, NS; 400 cm: mild stress, MS; 750 severe SS) along nitrogen (150 kg N/ha: high nitrogen, HN; 120 medium...

<title>Abstract</title> Melioidosis, an emerging tropical infectious disease and a global threat, lacks prediction model owing to the suboptimal information related incidences associated factors. This article focusses on spatial data analysis of melioidosis patients in India, country considered be endemic for disease. In this study, we screened over 20,000 articles identified 1,694 diagnosed with India between 1953 2023. We performed correlative patient profiles, case-reporting centers,...

Manning's roughness coefficient is one of the input parameters in many surface irrigation simulation models. It affects velocity flow and thereby its variation with time distance along field length influence water application. In this study, was studied for a furrow plot consisting three 40 m long free drained furrows parabolic shape having top width 0.30 m, depth 0.15 slope 0.5%. The experiments were carried out inflow rates 0.2, 0.3, 0.4, 0.5 L s1 ; 0.5, 0.6, 0.7 s−1 under bare; cropped...

Development of best management practices (BMPs) such as conservation tillage and winter cover crop to mitigate runoff reduce dissolved chemicals in irrigation is an important objective for controlling surface water pollution attributable agricultural activities. In this study, the effect standard (ST), ST with cropping (STCC), no-till (NT) on infiltration, runoff, organic carbon (DOC) export from furrow-irrigated fields 244-m length was investigated summer 2007 2008 irrigations.

Abstract Climate change evokes future food security concerns and needs for sustainable intensification of agriculture. The explicit knowledge about crop yield gap at country level may help in identifying management strategies agricultural production to meet demand. In this study, we assessed the rice under projected climate scenario India 0.25° × spatial resolution by using Decision Support System Agrotechnology Transfer (DSSAT) model. simulated results show that mean actual rainfed...

The application of nanomaterials as nanofertilizers is one the advanced solutions to overcome excessive use conventional fertilizers without compromising yield. In this study, synthesized urea-doped hydroxyapatite (UHN) at recommended (UHN_RD) and half-recommended (UHN_HRD) doses were compared with a dose commercial bulk urea fertilizer (BUF) control (CNT) treatment for nutrient availability in soil yield rice crops. Rice was grown 12 field columns (four treatments × three replications) by...

High residue loads associated with conservation tillage and cover cropping may impede water flow in furrow irrigation thus decrease the efficiency of delivery runoff quality. In this study, biomass effects on infiltration, runoff, export total suspended solids (TSS), dissolved organic carbon (DOC), sediment-associated (TSS-C), other undesirable constituents such as phosphate (soluble P), nitrate (), ammonium () from a furrow-irrigated field were studied. Furrow experiments conducted 91 274 m...
