Irrigated rice represents about 15% of the total area under rice in Africa. But this rice is expected to increase rapidly.
The adoption of high yielding varieties and intensive use of fertilizers led to a high production growth rate. The dominant source of production growth was increased yields which accounted for more than 60 percent of the of production increases. which are caused by major rice pests in the Philippines is vigorously pursued. The pest profile.
Irrigated rice philippines in Africa are often comparable to yields obtained in Asia, but there is a need for improved, high-yielding varieties, resistant to.
High-yielding varieties developed in the s and s at the International Rice Research Institute (IRRI) and elsewhere benefited farmers and the public, ultimately increasing yields and reducing the cost of rice to consumers.
Most of these varieties, however, did not have the optimum cooking quality that was possessed by many of the traditional varieties they replaced.
Inthe Cited by: The high cost of inputs, particularly fertilizer, hinders farmers from applying optimal fertilizer amounts to input-responsive high-yielding varieties. Rice variety opportunities.

The Green Super Rice is Developing property to multiple stresses such as drought, salinity, alkalinity, and iron toxicity.
It can also grow under. Hybrid rice therefore has two genetically different parents. As with other types of hybrids, hybrid rice typically displays heterosis (or hybrid vigor) such that when it is grown under the same conditions as comparable high-yielding inbred rice varieties it can produce up to 30% more rice.
With Philippine rice shortages and rising world rice prices, food security is a concern driving rice research into high-yield rice and tougher more resistant hybrid rice varieties in the Philippines. Philippine Rice Research Institute (PhilRice) has announced that its four new rice high-yielding varieties can help the country achieve self-sufficiency The output of these varieties was nearly double the current average rice yield per hectare.

Although the area under rice crop declined inoverthe area had expanded to reach million hecatre in The Philippines has recently been aiming to achieve self-sufficiency in rice. Recent programs and policies have been anchored on the development and adoption of high-yielding rice varieties in order to achieve this goal.
Thus, this paper aims to identify the factors that significantly affect the farmers’ adoption of high-yielding varieties such as hybrid and certified inbred rice.
Using a Author: Larry N. Digal, Shemaiah Gail P. Placencia. Avoid varieties that need to be planted or harvested earlier or later than surrounding rice fields to minimize pest damage (e.g., birds during maturation), and growth problems during times of harmful environmental conditions (e.g., late-maturing varieties running out of water) Resistance to lodging under normal farmer management.

High-yielding varieties of rice in the Philippines: progress of the seed-fertilizer revolution Item PreviewPages: High-Yielding Varieties.
The novel technological development of the Green Revolution was the production of novel wheat cultivars. Agronomists bred cultivars of maize, wheat, and rice that are the generally referred to as HYVs or "high-yielding varieties".
HYVs have. Five new inbred rice varieties that offer a challenge to hybrid rice’s yield have been released by the government and will be fielded out for technology demonstration all over Philippines’ 16 regions. The Philippine Rice Research Institute (PhilRice) has developed a.
This is a list of rice varieties, also known as rice are several species of grain called rice. Asian rice (Oryza sativa) is most widely known and most widely grown, with two major subspecies (indica and japonica) and o varieties. Also included in this list are varieties of African rice (Oryza glaberrima) and wild rice (genus Zizania).
The development and introduction of NHYV of rice in the Philippines is discussed. Equity and self sufficiency have been major objectives. Aliens have been excluded from all activities linked with the programme and a Rice Corn Board was early implemented to deal with problems in this respect.
The impact of the Philippine programme is analyzed, and the work of the IRRI at Los Banos is : Mahar K. Mangahas. Philippines - Agricultural development and prospects (English) Abstract. The concept of agricultural productivity penetrated the agricultural strategy of the Philippines after gains of the high-yielding varieties of rice became obvious.

Source: Manila Bulletin 24/07/ – The usual talk about rice these days center on hybrid is because the perception is that hybrids are high-yielding while the ordinary inbred or open-pollinated varieties (OPV) are very low-yielding.
For nearly two decades, the Philippine-Sino Center for Agricultural Technology, or PhilSCAT, has been testing and developing high-yielding rice varieties. According Bioregulators, chemistry and uses experts, cultivating hybrid seeds is one of the ways in which the Philippines can attain its goal of national rice self-sufficiency.
