Judicious application of saline water except for critical growth stages, could be the only practical solution to meet crop demand in arid and semi-arid regions, due limited access freshwater, especially during dry winter months. A field experiment was conducted study effect tillage [conventional (CT), reduced (RT), zero (ZT)], rice straw mulch deficit saline-water irrigation wheat (100, 80 60% requirement, CWR) followed by rainfed sorghum on soil properties yields cropping system. Yields...
Agricultural management practices alter soil characteristics and influence biological properties.Hence, a field trial was carried out to assess the 14-year long-term impact of tillage residue on activities microbial population in rice-wheat cropping system two depths viz., 0-15 15-30 cm.Soil organic carbon levels differed significantly (p > 0.05) across various treatments.Microbial biomass carbon, quotient, enzymatic were greater (10-82%) crop incorporation/retention treatments.Zero with...
The success of the sodic soil reclamation using elemental S (S°) depends on population native S° oxidizers. Augmenting flora soils with effective oxidizers can enhance reclamation. Present study reports for first time oxidation potential Sphingomonas olei strain 20UP7 isolated from pH
The perennial grass-legume cropping system benefits soil because of its high biomass turnover, cover nature, and different foraging behaviors. We investigated the response organic carbon (SOC) pools their stock to inorganic nutrient management in Guinea grass legume (cowpea-Egyptian clover) system.Depth-wise samples were collected after harvesting Egyptian clover. Based on ease oxidation with chromic acid, SOC oxidizable using Walkley-Black C method, very labile, less non-labile; dissolved...
The simultaneous occurrence of biotic and abiotic stresses affects the performance crops in salt–affected agro-ecologies. plant–microbe interaction, with effective rhizobacteria can effectively manage these stresses. This study characterized biocontrol, plant growth promotion, responsiveness wheat under salt-affected soils. Out 184 isolates, 20 isolates showed 41-72% inhibition fungal phytopathogens seedling blight (Fusarium sp.), head oxysporum), onion molds (Penicillium sp. and,...
Thermal Power Plant generates FGD gypsum as by-product during coal combustion. This study evaluates the characterization (spectroscopic and elemental), potentially toxic elements (PTEs) distribution, environmental risk assessment of for safe sustainable use in agriculture. The XRD SEM analysis confirmed dominance crystalline CaSO4·2H2O gypsum. order concentrations PTEs was Fe > Al Mn Zn Ni Co. residual fraction dominant pool, sharing 80-90% total PTEs. heavy metals (HMs) were below range...
The deterioration of soil biological health is the most important aspect associated with sustainability cereal-based food production systems. application organic nutrient sources widely accepted and recommended for sustaining crop productivity preserving fertility. Therefore, a study was carried out to assess effects different levels farmyard manure (FYM10: 10 t ha−1, FYM20: 20 FYM30: 30 ha−1), including inorganic fertilizer (NPK) on properties five high-yielding wheat cultivars (HD 2967,...
Salinity and sodicity are the major stresses in soils of arid semi-arid regions. These regions often face rainfall shortage groundwater contains excess salts with variable sodium adsorption ratio (SAR). Therefore, a laboratory experiment was conducted to investigate impact municipal solid waste compost (MSWC) reclamation saline-sodic soil pH, electrical conductivity (EC) exchangeable per cent 10.7, 3.09 dS m−1 70.3, respectively. Soil gypsum (25 50% requirement, GR) its combination 10 20 t...
Worldwide zinc deficiency in the soil under cereal production is a common problem affecting yield and nutritional value of several crops. Bioaugmentation with zinc-solubilizing bacteria can be promising option for increasing nutrition to The objectives study were evaluate Bacillus paramycoides improving yield, nutrition, availability rice grown sodicity stress caused by alkali water irrigation. Treatments included T1: control, T2: substrate, T3: paramycoides, T4: control (T1) + sulphate, T5:...
The soil organic carbon (SOC) content depends on the physiography, climatic conditions, type, and cropping patterns of a particular region. improvement in health contributes to better productivity soil. present study focused estimation profile predominant system Karnal Kaithal districts Haryana. Soil samples were collected at four different depths viz., 0–0.15, 0.15–0.30, 0.30–0.45 0.45–0.60 m from systems for pH, electrical conductivity, fractions calcium carbonate (CaCO3). was greater...
Restoration and improvement of soil quality is the prerequisite for ensuring agricultural productivity food security in India. Although intensification enhanced production, it led to a decline factor productivity, health environment, an impairment quality. The declined manifested through impaired ecosystem services also loss yield profitability. Soil organic C (SOC) considered as panacea maintaining improved microbial activities, water availability nutrient use efficiency. present review...
Globally, soil degradation is an important issue for sustainable crop production. Soil quality indicators are the attributes that address ecological functions of soil. Therefore, indicator-based assessment has been emphasized quantifying relative changes in different nutrient management systems. underthe rice (Oryza sativa L.) and wheat (Triticum aestivam cropping system was assessed using a modified “Soil Management Assessment Framework (SMAF)” model. Soil’s physical, chemical, nutritional,...
To make Indian agriculture remunerative, and enhance farmers’ income, the Government of India initiated a mission for doubling income (DFI) by 2022. For DFI under conventional cropping system, sector needs to grow @15% per annum. Therefore, there is need reorienting system with more productive alternative integrated farming combining on off-farm occupations high technological support. With this background, present study was carried out in cluster villages where interventions through research...
Abstract Soil and groundwater salinity associated with limited rainfall are the challenges for checking build‐up in semi‐arid regions. This field experiment was conducted to test impact of deficit saline irrigation (DSI) (in winter) mulching tillage on build‐up, yield nutritive value rainfed‐forage sorghum. Tillage (reduced, conventional zero), water (8.0 dS m −1 ) (100%, 80% 60% requirement [WR] wheat) mulch were allocated following split factorial layout. DSI produced at par wheat sorghum...
