Ratooning rice is an economical alternative to the second seasonal rice, thus increasing the yield of ratooning rice is highly important. Results Here we report an applicable transgenic line constructed through the manipulation of osa-MIRf expression in rice shoot using the OsGA3ox2 (D18) : Qing Liu, Yi Su, Yunhua Zhu, Keqin Peng, Bin Hong, Ruozhong Wang, Mahmoud Gaballah, Langtao Xiao. Management and ratoon rice. What about management? Ziska focused not only on planting dates but ratoon rice. “This is a kind of management used in rice and sugarcane — a way to cut the plant, add a fertilizer and get a second crop. Sometimes it takes minimal preparation and the yield can be up to 50 percent of the main crop.”.

The Rice Book I purchase this volume since it appeared to be more than just a recipe book. There are pages in my copy. The first 90 pages devoted to the history, culture, geography, agriculture and commerce surrounding rice in it various varieties.

The recipes are cover over pages (including 13 pages Rice ratooning book cooking methods)/5(4). Increasing and sustainable production of rice in tropical hill area is facing various problems where rice ratooning can overcome the limitations.

In this study; 22 rice entries were transplanted into experimental tank Rice ratooning book in the hill slope following Completely Randomized Design with five replications to asses’ agronomic performance of main crop and ratoon crop where Entry 13 Cited by: 7.

On an average, ratoon rice gives a yield roughly equivalent to 40 - 50 % as that of main crop with 40% reduction in crop duration (Krishnamurthy, ).

In addition, a ratoon crop can be grown with 50 % less labour and 60% less water than the main crop (Oad et al.,). Rice is one of the world's most important cereal crops and rice ratooning is one of the potential technologies to increase rice production. Based on land and water management, rice.

The rice ratooning offers an opportunity to increase cropping intensity per unit of cultivated area because a ratoon crop has shorter growth duration than the main crop. In addition, ratoon crop may be grown with 50% less labor. Rice ratooning is not a new concept for the rice breeder, but evaluating high yielding main crop and ratoon crop variety has a great prospect for tropical hill agriculture.

The marginal farmer of Malaysian hill area leave the field abandoned after harvesting the main crop and if they collect ratoon crop without any cultural practice, they can collect at least 8% grain Yield/Plant from Cited by: 7.

Ratooning is therefore perhaps one practical way of increasing rice productivity per unit land with less labour and input than the main crop as neither land preparation nor planting is needed for the ratoon crop (Sanni et al., ).

Studies on rice ratooning. Rice ratooning is one of the potential and attractive alternative technologies to increase rice production.

Based on land and water management, rice ecosystem is mainly divided into lowland. Downloadable. Increasing and sustainable production of rice in tropical hill area is facing various problems where rice ratooning can overcome the limitations. In this study; 22 rice entries were transplanted into experimental tank placed in the hill slope following Completely Randomized Design with five replications to asses’ agronomic performance of main crop and ratoon crop.

Rice ratooning is the practice of harvesting grain from tillers originating from the stubble of previously harvested crop. Comparative assessment of the engineering properties of main and ratooned NERICA rice varieties was investigated in this by: 1.

Ratooning rice is an economical alternative to the second seasonal rice, thus increasing the yield of ratooning rice is highly important.

Developing ratoon rice as forage could increase forage yield without extra demand on the fields in subtropical and temperate rice planting areas.

In this research, fourteen Indica rice varieties were first used in to select suitable ones as ratoon rice. The results indicated that the regeneration rate, regrowth tiller height, and the dry matter yield of Zhunliangyou were Author: Chenfei Dong, Nengxiang Xu, Chenglong Ding, Hongru Gu, Wenjie Zhang, Lei Sun.

Choose variety with good ratooning potential for main crop planting. Varieties with longer maturity are generally better for ratooning purposes. Harvaest at cutting height of not more than 30 cm. The shorter the cutting height, the yield is higher but maturity is longer.

The book examines 15 essential or beneficial nutrients used in irrigated, upland, and floating rice across a range of geographic regions. For each mineral, the text details the cycle in the soil–plant system as well as the mineral’s functions, deficiency symptoms, uptake in plants, harvest index, and use efficiency.

Ratooning is the agricultural practice of harvesting a monocot crop by cutting most of the above-ground portion but leaving the roots and the growing shoot apices intact so as to allow the plants to recover and produce a fresh crop in the next season. This practice is widely used in the cultivation of crops such as rice, sugarcane, banana, and pineapple.

Ratoon crops cannot be. The demand of water for irrigation purposes in Tanzania outstrips the amount of water available for irrigation and other demands. On the other hand, the demand for more food to feed the growing population is increasing, calling for the need to have technologies and farming practices that ensure more food production while minimizing water uses.

Although main crop rice (Oryza sativa L.) cultural practices are known to influence the subsequent ratoon crop, little specific information is available on the effect of many main crop management practices on ratoon crop objective of this study was to evaluate the effect of main crop harvest cutting height on ratoon crop agronomic performance, yield.

BACK TO THE FUTURE. THOUGHTS ON RATOON RICE IN SOUTHEAST AND EAST ASIA Ronald D. Hill School of Biological Sciences and Department of History The University of Hong Kong In China Oryza sativa has been grown as an annual for perhaps generations although ratooning certainly survived until about 3 years ago.

Ratoon cropping is an old system that has been practiced for many years, especially in the Tropics. Although the origin of ratooning is probably not known for any particular crop, it may have begun when man first noticed the regrowth of new shoots following the cutting of certain crops at harvest, thus, producing a new crop without replanting.

Rationing in Cuba refers to the system of food distribution known in Cuba as the Libreta de Abastecimiento. The system establishes the rations each person is allowed to buy through that system, and the frequency of supplies.

Despite rumors of ending, the system still exists. As ofa coupon book taken to a ration shop provided family minimums for rice, sugar. Ratoon cropping is growing a fresh crop from the stubbles or suckers of the plant crop without replanting. It is also referred to as stubble cropping, re-harvesting, second crop, etc.

Ratoon cropping is used extensively in sugarcane, bananas and plantains, pineapple, forage crops and minor fibre crops such as abaca and ramie; and to a limited extent in rice, sorghum, Author: B. Sundara. Thorough coverage of rice, from cultivar development tomarketing Rice: Evolution, History, Production, and Technology, the thirdbook in the Wiley Series in Crop Science, provides unique,single-source coverage of rice, from cultivar developmenttechniques and soil characteristics to harvesting, storage, andgermplasm resources.

The results show that proper main crop harvest cutting height can increase ratoon yields, but selecting a cultivar with inherent ratooning ability is also essential to successful rice ratooning.

Journal Series no. R To further explore the opportunities in ratoon rice development in China and other major rice producing countries, an International Symposium on Rice Ratooning was held on October in Qichun County, Hubei Province, where large field experiments on rice ratooning were conducted by a team from Huazhong Agricultural University.

The third most important cereal crop after wheat and corn, rice is a staple food for more than half of the world’s population. This includes regions of high population density and rapid growth, indicating that rice will continue to be a Pages: Ratooning of rice eliminates two labor‐saving operations: raising seedlings in the seedbed and transplanting in the main field.

Field experiments were conducted for 2 years on Maahas clay (an isothermic clayey mixed Aquic Tropudalf) to evaluate the performance of rice cultivars for ratooning ability and the agronomic practices that affect. Double cropping (main+ratoon) of IR produced q/ha of grain yield compared to q/ha under improved monocropping of rice variety Sahsarang Ratooning ratooning Subject Category: Techniques, Methodologies and EquipmentCited by: Rice Ratooning.

In areas where adequate water is available after the first crop season, rice ratooning could be practised as an alternative to raising of the second crop in rice double cropping. The ratoon crop matures earlier and requires less labour and water inputs.

Water use efficiency is high.

Yang et al. [16] began to study on the ratooning rice in China in But the yield of the ratooning rice is still lower than the main cropp; so it was only planted in small areas. However, compared with the traditional rice cultivation, ratooning rice can provide higher resource using efficiency per unit time and per unit land area.

Background. Rice (Oryza sativa L.) represents an important food crop worldwide and can produce panicle-bearing secondary tillers (i.e., ratoons) following harvest [].The production of a second rice crop in one cropping season is known as ratooning.

The ratoon crop develops by regenerating rice tillers from nodal buds of the stubble that is left behind after the first seasonal rice.

Recent and projected climate data indicated an ongoing increase in air temperature and growing season length with latitudes above ∼31 °N. We then applied the DD50 growing degree day model to these data to determine if ratooning, a management practice that produces a second rice harvest with minimal resource input, could be employed.Morphology and Development of the Rice Plant MORPHOLOGY Cultivated rice is generally considered a semiaquatic annual grass, although in the tropics it can survive as a perennial, producing new tillers from nodes after harvest (ratooning).

At maturity the rice plant has a main stem and a number of tillers. Each productive tiller bears a terminalFile Size: KB.
