  • arrow Field Experiments at El-Gemmiza, Agricultural Research Station Considers Responses to SRI Management by Various Genotypes
    [December 20, 2017] Field Experiment was carried out in summer seasons of 2014 and 2015 at the Experimental Farm of Rice Research Section, El Gemmiza Agricultural Research station, Gharbia Governorate, Egypt. The study was conducted to determine the response of three rice genotypes (Sakha 106, Giza 179 and Hybrid 3), two types of fertilization (chemical and compost fertilization), weeding control (hand weeding and chemical control) and plant density (one, two and three plants/hill) on yield and its attributes traits. Genotypes significantly differed in all studied traits. Hybrid 3 genotype produced the maximum values of no. of tillers and panicles/m², length of panicle, no. of total grains per panicle, and 1000 grain weight as well as yield of grain/fed, while the lowest values of these traits were recorded with Sakha 106 genotype. The study concludes by recommending different adaptations of SRI for different varieties: Planting one plant/hill was suggested for Hybrid 3 genotype, two plants/hill for Giza 179 genotype, and three plants/hill for Sakha 106 genotype. Also recommended were organic fertilization with compost and using hand weeding. (It was not clear in the study how altering the spacing would change the outcome.) [See article by Attia et al (2017) for details, including discussion of weeding and fertilization.]

  • arrowSRI Research Published in Minufiya Journal of Agricultural ResearchDuring 2013, researchers from Kafrelsheikh University and the Field Crop Research Institute in Egypt had an article published in the Minufiya Journal of Agricultural Research. The article by M. O. Abdelhamed et al entitled “Evaluation of some System of Rice Intensification (SRI) treatments and its effect on rice production” reported on two field experiments performed during the 2009 and 2010 rice season at the experimental farm of the Rice Research And Training Center (RRTC) Sakha, Kafr El-Sheikh, Egypt. The effect of several SRI treatments on a hybrid rice cultivar (H1) were studied: Irrigation type (flooding and just saturated), seedling age (15, 20 and 25 days after sowing) and spacing between hills (20×20, 25×25 and 30×30 cm).The youngest age of seedlings gave the highest LAI and dry matter in both seasons for all samples, while 20×20 cm spacing surpassed the two wider spacings for both traits. Saturation irrigation gave the highest number of tillers/m2 and number of panicle/m2 in the 2009 season. Young seedling age (15 DAS) and the hill spacing of 20×20 cm recorded the highest values for number of tillers/m2 and number of panicles/m2 and also recorded the highest number of filled grains/panicle in both seasons. The paper concluded that flood irrigation, seedling age of 15 days old and hill spacing of 20×20 cm produced the highest grain and straw yields /ha as well as the highest harvest index in both seasons. (See article abstract for details.) [Note: while this study found the closest spacing (20 x 20cm) to be optimal, the thesis noted below found that the 30 x 30cm spacing together with 15 day old seedlings produced the best results.]
  • arrow Mansoura University Thesis Documents Effect of SRI Methods on ProductivityA 2012 Mansoura University master’s thesis by Tamer Elhefnawy described the effect of SRI on productivity of rice at the Agricultural Research station at El-Gemmiza, in Egypt’s Gharbia Governorate. Two field experiments were carried out during the two successive summer seasons of 2008 and 2009 in order to determine the effect of cultivars, seedling age and spacing between plants on growth, yield components as well as milling recovery. Elhefnawy concluded from his study that Egyptian Hybrid 1 cultivar grown with the youngest seedling age (15 day old) and widest spaces between hills and rows (30 × 30 cm) under SRI methods could be recommended to raise rice productivity under the environmental conditions at the Rice Research Agricultural Research station in El-Gemmiza.
2009-2010 Updates
  • arrow Three Seasons of Trials with SRI Methods Show Benefits on Normal and Saline SoilsDr. Waled Elkhoby, Rice Research and Training Center, Sakha, Kafr El-Sheikh (Field Crop Research Institute, Agriculture Research Center) has carried out three seasons of experiments using SRI methods under both normal and saline soils during 2008-2009 (see preliminary report). The trials on normal soils were conducted at  the Sakha research station and those on saline soils were undertaken at the El-Sirw research station. The goal was to reduce the inputs needed for rice cultivation, such as lower seed rates, water, fertilizers, pesticides, and herbicides.Field experiments indicated that the amount of irrigation water applied using SRI methods can be reduced to 35% compared with the conventional method of continuous flooding. The rate of seeding can reduced to 50 kg/ha for the inbred rice and 15 kg/ha for the hybrid rice. Grain yield with SRI methods was more than 12 ton/ha for the inbred rice and 15 ton/ha for the hybrid rice. Researchers found that young seedlings less than 15 days old spaced at 20×20 cm between hills were suitable for saline conditions, and that bed planting methods could save more water. Under normal soils, SRI methods also gave very promising results with rice grain yield and water saving.

    Additional experiments will have to be conducted in order for the government to decide to disseminate SRI through a national technology transfer program. One of the major constraints to increasing rice production with SRI methods in Egypt is the scarcity of well-trained expertise.

2008 Updates
  • arrow Egypt Becomes Thirty-first Country to Report Positive SRI ResultsDr. Walid El-Khoby, researcher at the Rice Research and Training Center at Sakha, has reported on trials conducted at his Center which showed SRI yields of 10.7 tons per hectare with inbred improved varieties, and 13.9 tons per hectare with hybrid varieties. Since Egypt’s national average yield at 9.5 tons per hectare is the highest in the world, these yield increases are not as great in percentage terms (12.5% and 46%) as in some other countries. However, they were achieved with a 35% reduction in water use and Egypt SRI Trialsone-third lower costs of production, which makes the results attractive in Egypt.
  • arrow Mustapha Ceesay Visits SRI Trials at Rice Research and Training CenterIn August 2008, Dr. El-Khoby and colleagues at the Rice Research and Training Center and their SRI trial plots were visited by Dr. Mustapha Ceesay, research director of the Gambia’s National Agricultural Research Institute, who was attending an international rice conference in Cairo. Ceesay, who has been evaluating SRI in the Gambia since 2000 while still a graduate student at Cornell, shared his considerable experience with SRI practices with Egyptian colleagues (see Ceesay’s report and photo at right).
