Rice straw was fermented with Cellulomonas sp. and Alcaligenes faecalis. Microbial cells and undigested residue, as well as chemically treated (NaOH or NH4OH) and untreated straws, were analyzed for nutrient composition and in vitro digestibility. In a typical fermentation, 75% of the rice straw substrate was digested, and 18.6% of the total substrate weight that disappeared was recovered as mi...
considering the increasing rice consumption in the world and also the excessive application of pesticides to increase production, an experiment was conducted to determine the pesticide residues and their effects on nitrogen, potassium and phosphorus content of hashemi, khazar and gohar (sa13) rice cultivars, in a factorial design at randomized complete block design with three replications. in t...
investigating the decomposition of crop residues using woodborn and soilborn saprophytic fungi this experiment was conduceted to evaluate the effect of some fungi on decomposition of crop residues. crop residues from rice, wheat, cotton, canola and soybean were inoculated with pleurotus ostreatus, phanerochaete chrysoporium, aspergillus niger and trichoderma viride in vitro. after 30 days, hemi...
This study examines the effects of tillage, residue management and cropping system intensification through the inclusion of green gram on the performance of the rice-wheat (RW) system in NW India. We hypothesized that zero tillage (ZT) with residue retention provides a means of sustainably intensifying the RW system through lower production costs and higher economic profitability, whilst at the...
Disposal of agro-residue and escalating energy demand are the two major problems developing countries, which can be resolved with co-generation techniques. Several alternative generating techniques available for optimal usage agro residue. Among diverse alternatives, briquetting stands out as one sustainable technique, defined process conversion biomass organic residues through compaction densi...
An experiment was conducted during 2020–21 at the Rani Lakshmi Bai Central Agricultural University, Jhansi, Uttar Pradesh to study effect of tillage, rice (Oryza sativa L.) residue, weed control and N fertilizer levels on weeds, growth yield wheat (Triticum aestivum L.). Weed infestation in zero-tillage (ZT) significantly lower (16.7–27.6%), more so when rice-residue retained soil surface compa...
Rice yellow mottle is the most important virus disease of rice in Africa. The disease is a major constraint due to its wide geographical distribution and the extent of yield losses it induces. The role of the causal agent Rice yellow mottle virus (RYMV) in virus–host interactions was studied in relation to the current knowledge of rice genetics. Most cultivated rice varieties are susceptible to...
For the first time, a multi-residue methodfor simultaneous determination of 41LC-amenable pesticides in rice, belonging to different chemical classes has been developed in Iran by LC-MS/MS. The pesticides were analyzed simultaneously in a single run using positive electrospray ionization with multiple reaction monitoring (MRM) after extraction with slightly modified QuEChERS method. The calibra...
Conservation Agriculture (CA) is still a relatively new approach for intensively cultivated (3 crops yr -1 ) rice-based cropping systems that produce high crop yield and amounts of residues annually. With the recent development transplanting rice into tilled strips on non-puddled soil, CA could become feasible patterns. However, effect increased retention response to nitrogen (N) fertilization ...
