Kenya experiences huge production-consumption deficit in relation to rice. This is due to changing eating habits that has adopted more rice in the menu and rapidly rising population. Rice production has remained low being unable to meet consumption. Rice ecosystems in Kenya include irrigated, rainfed lowland and rainfed upland. Irrigated ecosystem has over the years been given more emphasis despite rainfed rice farming having double the potential over irrigation system. Ecologically rice grows well in abundant water supply, warm to high temperatures and in Clay sandy to loamy soils with slightly acidic to neutral pH. Rice varieties grown in Kenya are mainly traditional, introduced improved, hybrids and landraces. Rainfed rice farming faces constraint’s key among them being; drought and erratic rainfall, weeds, pest and diseases, cheap imports, land ownership and poor infrastructure. Mitigating against drought and erratic rainfall, improving farm inputs and equipment, increasing germplasm production and distribution, credit support and marketing to farmers, improving farmers skills through technological transfers and infrastructural development are prospects that if adopted could increase rainfed rice productivity. More attention towards improvement of rainfed rice farming could greatly contribute to bridging the production-consumption deficit that is bridged through imports. It is with this, that this review updates our understanding of rain fed rice farming in Kenya in terms of ecological conditions, ecological systems, varieties, constraints and prospects.

AbstractDrought and phosphate availability are two major abiotic factors limiting productivity of rice in rainfed upland areas. There has been a constant need for new improved donor with tolerance to multiple abiotic stress conditions for rainfed rice breeding. In the present study, a set of 32 popular rice varieties and landraces were evaluated for drought and low-phosphorus (P) tolerance, and also characterized using grain yield under reproductive drought QTLs (DTY QTLs) and Pup1 linked/specific molecular markers. Twenty-seven genotypes were identified as tolerant to moderately tolerant to drought. The SSR markers linked to ten DTY QTLs classified the genotypes into two groups corresponding to aus and indica. The tolerant genotypes were distributed under both groups. Based on the core markers of Pup1 locus, complete tolerant haplotype was recorded in nine genotypes other than the tolerant check Dular. Nine more genotypes showed the incomplete tolerant haplotypes. The rice genotypes showed significantly high genetic variability for low-P tolerance in hydroponic study. A few genotypes revealed non-Pup1 type tolerance which needs further confirmation.

In obtaining stable and high rice yields, the leading role belongs to the use of the best varieties, harmoniously combining productivity and technological indicators of grain and milled rice quality, adapted for cultivation in the main rice-growing regions. Therefore, the aim of our research is to evaluate new rice genotypes by a set of economically valuable traits that can replace obsolete varieties in the sowing area of the region and the country as a whole for industry efficiency. Experimental plots of competitive variety testing (CVT) were laid on the territory of the rice irrigation system of the experimental production department of the Federal Scientific Rice Centre, Belozerny, Krasnodar region for three years. The results are processed by analysis of variance and correlation analysis. All new varieties formed dense panicles of 10.0-11.9 pcs / cm with a sufficient number of fertile spikelets 139.7-165.9 pcs. on average, which is responsible for the high grain content of agrophytocenosis 44.1-58.2 thousand units/m2. Hence the high grain yield - 9.2-10.2 t / ha with a good combination of the main technological indicators - the mass of 1000 grains and head rice content. The closeness of the interconnections of the main economically valuable traits and the heat supply of the growing season is determined. Four varieties (except VNIIR 10284) show a neutral yield response to one of the main factors of external influence on the plant - the sum of effective temperatures above 15 ° C. According to the results of the test, for three years in CVT and in the environmental testing, the variety Romans was transferred to State variety testing, VNIIR 10279 is being prepared for transfer.

Tidal swamp lands are marginal lands with considerable potentials for rice farming. The key solution to overcome swampy lands constraints are nutrient and water managements as well as the use of adaptive rice varieties. Inpara (inbred swampy land rices) varieties have been released by the Indonesian Agency for Agricultural Research and Development (IAARD) which are adaptive to swampy land conditions. The purpose of this research was to evaluate the adaptability of Inpara varieties in tidal swamp lands with type B overflow. The field experiment was carried out in Karang Bunga village, Barito Kuala District, South Kalimantan Province, in the  dry season  from April to August 2016. The research was arranged in randomized complete block design, with 3 replicates. The varieties tested, i.e., Inpara 1, 2, 3, 4, 5, 6, 7, 8, 9, and check varieties Margasari, Ciherang, and Mekongga. The results showed that the adaptability varied among varieties tested. Inpara 3, 4, 6, 8, and 9 had high yield and good adaptation on tidal swamp land yielded 3.475-4.299 ton ha-1. These varieties produced between 38.5 to 71.3% higher than Margasari and 51.4 to 87.2% higher than Mekongga. Inpara 3, 4, 6, 8, and 9 could be used as a main varieties in the tidal swamp lands.<br /><br />Keywords: rice, swampy land, variety
