The studies conducted on mode of perpetuation of sheath blight pathogen (Thanatephorus cucumeris) of rice (Oryza sativa L.) in/on rice seeds, plant debris and through sclerotia was studied at different placement conditions viz., on soil surface, at 5 cm soil depth and in-door under roof cover after crop harvest. The rice seeds were found to harbour externally viable pathogen up to five months from the harvest.

Rice residues are important natural resources, and recycling of these residues improves the soil physical, chemical and biological properties. Management of rice straw is a major challenge as it is considered to be a poor feed for the animals due to high silica content. A field experiment was conducted at Agricultural Research Station, Bhavanisagar during 2014-2015 and 2015-2016 to review the suitable rice residue management practices and nutrient dynamics by using combine harvester operated rice field after cultivating rice.

Two consecutive field experiments after rice crop were conducted during 2011-12 and 2012-13 in the Crop Research Centre, of Sardar Vallabhbhai Patel University of Agriculture and Technology, Uttar Pradesh. Ten different treatments were implied to evaluate the residual effect of vermicompost and applied inorganic fertilizers on wheat crop. Significantly taller plants than T2 during both the years were measured in those treatments where 4 ton vermicompost was applied in rice.

A Structural Equation Model has been used to investigate the multidirectional causal relationship among agricultural characteristics such as nitrogen content in the soil (kg/ha), Rice yield (kg/ha), nitrogen uptake by rice (kg/ha) and organic carbon (kg/ha). There using time series data of experimental project on Raipur district of Chhattisgarh from 1993 to 2017, this paper investigates the separate but simultaneous impact of different character on yield.

Fomesafen is widely used as herbicide for weed control. Fomesafen have both foliar and soil activity. It mostly control broadleaves. Fomesafen is labeled for postemergence applications to soybeans, peanuts, and rice. Although bronzing or burning of soybean leaf tissue is evident after application, yield is rarely affected. The present study was designed to evaluate the effect of repeated exposure of Fomesafen (Herbicide) by oral gavage method on the blood biochemistry of female wistar rats.

A long-term field experiment was conducted to design and implement alternative production systems with increased resource use efficiency, productivity and to determine the effect of tillage systems and mineral fertilizers on soil organic carbon patterns. This experiment intended to evaluate the effects of these management strategies on soil structural formation and structural stabilization of a sandy loam soil. The shift from puddled - transplanted rice on the flat land to raised bed systems affects the productivity and resource use efficiency of the rice-wheat system.

A field experiment was conducted during kharif season of 2015 and 2016 to study the effect of integrated nutrient management (INM) practices on soil biological properties in rice. The experiment was laid out in randomized block design with eight treatments including six INM practices, one chemical practice and one control (i.e. no N) with three replications. The results revealed that biological properties of soil were significantly enhanced by the application of combined use of organic and inorganic fertilizers after harvest of crop during both the years of experimentation.

An experiment was carried in factorial concept with two factors i.e., varieties at two levels and rooting media at eight levels thus making 16 combinations which were replicated twice. The effect of varieties, rooting media and their interactions were found to be significant on different rooting parameters. Among the rooting media, the greatest percentage of rooted cuttings was recorded by M8 – soil:vermicompost : coco peat : saw dust (1:1:1:1) v/v + mycorrhiza.
