Effect of integrated nitrogen management on soil properties and yield of wheat in salt affected soil

Effect of integrated nitrogen management on soil properties and yield of wheat in salt affected soil

Field experiment were conducted at the Student Instructional Farm of Narendra Deva University of Agriculture and Technology, Narendra Nagar, Faizabad (U.P.), India, to study the effect of integrated nitrogen management on soil properties and yield of wheat in salt affected soil. The result showed that maximum grain yield and available nitrogen were recorded in treatment receiving 1:1 ratio of urea + pressmud (T7) whereas, maximum build up in organic carbon in plot receiving 1:3 ratio of urea + FYM (T5). Increasing dose of organic sources of nitrogen improved the pH, EC, ESP and hydraulic conductivity of salt affected soil. The highest available P and K were estimated in Treatment T8 (U-N30+PM-N90). However, recommended dose of Chemical fertilizers significantly superior with respect to zinc availability.

Review on growth and yield of rice (Oryza sativa L.) as influenced by spacing and nutrient management practices

Rice plant population and nutrient management is the key for higher productivity. In due course of PhD work on a neglected red rice crop which is grown by tribal’s peoples of bastar plateau since time immemorial. Very few literatures are available on package and practices of red rice. This study has gone through several research papers concern with plant geometry and nutrient management in rice crop. In climate change era the land races of rice are capable to mitigate the effect of changing environment, when the frequency and intensity of rainfall is unpredictable.

Effect of continuous application of organic and inorganic sources of nutrients on chemical properties of soil

Effect of continuous application of organic and inorganic sources of nutrients on chemical properties of soil

Continuous applications of organic manures and inorganic fertilizers have been reported to affect soil pH, electrical conductivity, Soil organic carbon, available N, P and K. Electrical conductivity has been used as chemical indicator of soil biological quality in response to crop management practices. Continuous application of organic manure and inorganic fertilizer decreased soil pH but increased total soluble salt concentration. Soil organic carbon, available N, available P; and water soluble, exchangeable and total K were significantly increased with the conjoint application of organic manure and inorganic fertilizer whereas the concentration of non-exchangeable K was significantly decreased with combined application of organic manure and inorganic fertilizer in comparison to application of fertilizer alone. Thus the use of organic and inorganic sources of nutrients improved chemical properties of soil, ultimately soil health and productivity.

Effect of soil applied granular insecticides on microbial population in sugarcane grown soil

Effect of soil applied granular insecticides on microbial population in sugarcane grown soil

A field experiment was conducted at Main Sugarcane Research Station Farm of Navsari Agricultural University, Navsari. Four treatment of insecticides viz. T0 Control, T1 Phorate 10G (1.5 kg a.i./ha), T2 Carbofuran 3G (1 kg a.i./ha), T3 Chloran traniliprole 0.4G (0.1 kg a.i./ha) were taken and applied at 60 days after planting. The soil samples were periodically collected at 1, 10, 30, 60 days after application of phorate and at the time of harvest and analyzed on the same day by serial dilution technique. The total bacterial count was significantly higher in treatment of phorate but remained statistically at par with treatment of chloran traniliprole and carbofuran. The total bacterial count was also significantly higher at the time of harvesting of sugarcane. The treatment receiving phorate gave significantly higher actinomycetes population in soil but remained at par with the treatment of carbofuran. In case of days after application, the total actinomycetes population was significantly higher at the time of harvest of sugarcane. The application of insecticides didn’t show any significant effect on fungi population. However, in case of days after application the significantly higher fungi population was found at the time of harvest of sugarcane but remained statistically at par with fungus population at 60 days after application of insecticides.

Effect of integrated nitrogen management on yield of rice and chemical properties of sodic soil

Effect of integrated nitrogen management on yield of rice and chemical properties of sodic soil

A field experiment on “Effect of integrated nitrogen management on yield of rice and chemical properties of sodic soil” was conducted at the Agronomy Farm, College of Agriculture, Anand Agricultural University, Vaso during kharif season 2017. The experiment was laid out in a randomized block design with ten integrated nitrogen management (INM) treatments and four replications. Experimental result revealed that the treatment receiving 50% RDN through castor cake + 50% RDN through inorganic fertilizer (T7) recorded significantly higher grain yield (4461 kg ha-1 ) as compared to application of 100% RDN through inorganic, FYM and vermicompost but it was at par with rest of the treatments. However, straw yield (7974 kg ha-1 ) was observed to be significantly higher with the treatment receiving application of 100% RDN through castor cake (T4) than other treatments except treatment receiving 100% RDN through FYM (T2) as well as 50% RDN through castor cake and 50% RDN through inorganic fertilizer (T7). The organic carbon content of soil as well as available status of nitrogen, phosphorus, potassium were remarkably improved and also significantly reduced the ESP after harvest of rice crop due to the application of treatment receiving organic manures alone or in combination with inorganic fertilizers.

Effect of climate change on soil chemical and biological properties - A review

Effect of climate change on soil chemical and biological properties - A review

Climate change influences composite set of measurable physical, chemical and biological soil properties attributes which relate to functional soil processes. Climate change impacts soil chemical, physical and biological functions through a range of predicted global change drivers such as rising atmospheric carbon dioxide (CO2) levels, elevated temperature, altered precipitation (rainfall) and atmospheric nitrogen (N) deposition (French et al., 2009). The exact direction and magnitude of these impacts will be dependent on the amount of change in atmospheric gases, temperature, and precipitation amounts and patterns. Many studies have progressed our understanding of relationships between particular soil properties and climate change drivers, e.g. responses to temperature, CO2 or rainfall. The complexity and interdependence of many of the climate change drivers influence soil microbial properties like microbial biomass and biomass diversity, rate of organic matter decomposition, C and N cycles, chemical properties of soil like pH, EC, nutrient availability and physical properties like porosity, aggregate stability, soil erosion, etc.
