In the process of rice harvesting, passability track combine harvester is often limited by state soil. Meanwhile, wet and soft paddy soil compacted under rolling harvesting machinery, which also affects function ecological environment. Therefore, relationship between physical mechanical properties was studied in this paper. addition, compaction from a on field with without stubble studied. The ...

The steroid hormone 20-hydroxyecdysone (ecdysone) is the key regulator of postembryonic developmental transitions in insects and controls metamorphosis by triggering the morphogenesis of adult tissues from larvae. The Rho GTPase, which mediates cell shape change and migration, is also an essential regulator of tissue morphogenesis during development. Rho activity can modulate gene expression, i...

Two experiments tested the use of lupin grain as a supplement for weaners grazing wheat stubble. The control groups in both trials received no supplement until liveweights dropped to 22 kg and then lupins were fed. In 1984 two lick-blocks were tested; the Rumevite "Sheep and Cattle" block and the ICI "Ultrapro 30" block. Liveweight changes of animals on the control (5 weeks), Rumevite block, IC...

While writing a report on ' The present u of naturalistic measures in the control malariaHackett, Russell, Scharff and Sen* White (1938) found that there was a difference of opinion among themselves as to the effect rotting stubble in water in rice fields after re^F ing. Therefore, Senior White asked all t I malaria inspectors working under him, includi ? the present writer, to select a typical...

For sustainable productivity, a winter wheat (Triticum aestivum L.)–summer crop (corn [Zea mays L.] or grain sorghum [Sorghum bicolor L.])–fallow (W-SC-F) cropping system could benefit from optimal stubble cutting height management, but only limited information is available. The objective of this study was to evaluate the effect on subsequent corn and yields, available soil water, water use, pr...

Stubble burning in Chile is a common practice used for the farmers but it causes nutrient losses, erosion and environmental pollution. An alternative to change this situation incorporation of crop residue improve soil quality. The objective research was compare effects oat stubble on chemical physical properties an Humic Haploxerands with rotation oat-wheat. A completely randomized experimental...

The problems of atmospheric pollutants are causing significant concern across the globe and in India. aggravated level surrounding environment poses serious threats to normal living conditions by deteriorating air quality adverse health impacts. Pollutant concentration increases during harvesting seasons Kharif/Rabi due stubble burning is other points or mobile sources. present study intended m...

A two-year field study was conducted to investigate the performance of a lightweight trash-board moldboard plow (with and without a trash-board), as influenced by stubble height and water content. Both fields were measured for the performance of a trash-board moldboard plow when used during the optimization of the plowing depth, the water content, and the reaction forces. The results showed tha...

The investigation was undertaken to enhance the decomposition process by pre-treatment of rice stubble, having higher concentration of lignin. Air-dried rice stubble was treated with 1.8 liter of 1% NaOH and autoclaved. Six cellulolytic fungi, Trichoderma harzianum, Penicillium citrinum, Curvularia lunata, Aspergillus flavus and Alternaria alternata were grown in basal synthetic medium along wi...
