ABSTRACT Nitrogen (N) is a major lacking nutrient element for the growth and yield of cereal crops Calabar, it is necessary to determine the response different sources and rates of N  in four varieties of upland  rice. Treatments comprised factorial combinations of the four rice varieties (NERICA 1, NERICA 2, FARO 45, FARO 48), three straight inorganic N sources (urea, Calcium ammonium nitrate, ammonium sulphate) and four levels of N (0, 30, 60, 90 kg N ha-1) laid in randomized complete block design. The N was split applied twice; one-third at the beginning of tillering and the remainder at panicle initiation. The results showed that the source of fertilizer N did not affect significantly the growth and yield of the rice crop (p=0.05). Considering that soils in Calabar are acid sands it will not be advisable to consistently apply such acidifying fertilizers as ammonium sulphate or urea except with soil liming which will undoubtedly increase the cost of production and probably make it unprofitable to cultivate rice in the area. The fertilized crop grew taller and produced more biomass compared with the control. It also produced significantly more tillers hill-1, panicles m-2, grains panicle-1, weight of 1,000 grains and grain yield. However, whereas NERICA 1, NERICA 2 and FARO 45 were more responsive to lower N levels, the grain yield of FARO 48 was significantly higher when the crop received 90 kg N ha-1 compared with other varieties, probably because of its longer growth duration in the field.  The responsiveness of these varieties to low N application was the result of their higher grain yield resulting from enhanced N use efficiency. Genotypes that were most responsive to low N input levels were early maturing with high N-use efficiencies. On the basis of grain yield, it is recommended that for  high yield in the humid region of Cross River State, N should be applied at the rate of  60 kg ha-1 for early-  and 90 kg ha-1 or above for the medium-maturing upland rice varieties.

ABSTRACT The upland rice farmers in Suriname use local varieties and low level technologies in the field. As a result, the upland rice grain yield is low, at about 1 000 kg ha-1. Our objective was to evaluate the use of upland rice cultivars from Suriname and Brazil, and the effect of nitrogen, N, phosphorus, P, and potassium, K, fertilizers on cultivation variables. We undertook four field trials in the Victoria Area, in the Brokopondo District, using a randomized block design each with four replications. The most productive rice varieties were BRS Esmeralda (grain yield 2 903 kg ha-1) and BRS Sertaneja (2 802 kg ha-1). The highest grain yield of 2 620 kg ha-1 was achieved with a top dressing application of 76.41 kg N ha-1 20 days after sowing. For P, the highest grain yield of 3 085 kg ha-1 was achieved with application of 98.06 kg ha-1 P2O5 applied at sowing. An application rate of 31.45 kg ha-1 of K2O at sowing achieved the highest grain yield of 2 952 kg ha-1. Together, these application rates of N, P and K resulted in rice grain yield of about 3 000 kg ha-1, which is three times greater than the national average for upland rice. We demonstrate that the use of improved rice varieties matched to the local conditions, and application of appropriate fertilizers, are management practices that can result in significant increases in rice grain yield in Suriname.

Abstract Drought is an important stress phenomenon in Bangladesh that greatly hampers crop production. So, it is imperative to develop drought-tolerant rice varieties. Low-yielding, non-uniform flowering and late-maturing Africa rice - New Rice for Africa (NERICA), viz. NERICA-1, NERICA-4 and NERICA-10 varieties - were irradiated with different doses of gamma-rays (250, 300 and 350 Gy) in 2010. M1 plants were grown and M2 plants were selected based on earliness and higher grain yield. The desired mutants along with other mutants were grown as the M3 generation during 2011. A total of 37 mutants from NERICA-1, NERICA-4 and NERICA-10 were selected on the basis of plant height, short duration, drought tolerance and high yield in the M4 generation. In the M5 generation, six mutants were selected for drought tolerance, earliness, grain quality and higher yield. With respect to days to maturity and grain yield (t/ha), the mutant N1/250/P-2-6-1 of NERICA-1 matured earlier (108 days) and had higher grain yield (5.1 t/ha) than the parent. The mutant N4/350/P-4(5) of NERICA-4 also showed a higher grain yield (6.2 t/ha) than its parent and other mutants. On the other hand, NERICA-10 mutant N10/350/P-5-4 matured earlier and had a higher yield (4.5 t/ha) than its parent. Finally, based on agronomic performance and drought tolerance, the two mutants N4/350/P-4(5) and N10/350/P-5-4 were selected and were evaluated in drought-prone and upland areas during 2016 and 2017. These two mutants performed well with higher grain yield than the released upland rice varieties. They will be released soon for commercial cultivation and are anticipated to play a vital role in food security in Bangladesh.

Thirteen traditional upland rice varieties (Kadidit Pilit, Red 64, Masipag 9, Masipag 15, Dinorado, Mindoro, Camuros, Masipag 22, Palawan, Suleg, Biday, Pilit , Pilit Talacdan) were evaluated in Randomized Complete Block Design (RCBD) in three replicates at the experimental area of Central Philippines State University (CPSU), Kabankalan City, Negros Occidental from November 2012 - April 2013. The parameters compared were their agronomic data on growth and yield, including grain characteristics. These data were processed using the one-way Analysis of Variance (ANOVA) with the Statistical Tool for Agricultural Research (STAR) (Version 2.0.1) while Duncan’s Multiple Range Test (DMRT) were used to compare significant treatment means at 1% level. The upland rice varieties showed significant variation in growth, yield showed distinct grain characteristics. Biday variety was the tallest, produced longer and wider leaves, and bore the longest panicle. Mindoro and Masipag 22 produced the most number of tillers. Pilit talacdan had the biggest culm, produced the heaviest panicle, with the highest number of filled grains per panicle. Pilit variety gave the heaviest weight of 1,000 grains. The grain features were also found to be distinct in each variety. The yield significantly varied among the upland rice varieties. Pilit and Pilit Talacdan gave the highest yield among the varieties grown at CPSU condition. The performing varieties would be used for upland rice improvement and breeding program and for further verification in the farmer’s field.

The experiment was conducted at the Bangladesh Rice Research Institute Farm, Gazipur, in boro season to determine the optimum planting date and to select the varieties having high yield potential. Traditional aromatic photoperiod sensitive fine rice varieties; Kalijira, Kataribhog, Chinigura and Badshabhog were transplanted from 10 December and continued up to 25 January, both in 2000 and 2001 years, at an interval of 15 days. Forty-day old seedlings were transplanted spaced at 20 cm x 20 cm. Results exhibited that plant tallness, number of tillers and dry matter increased with the advancement of planting dates. On the contrary, the number of panicles, grains panicle-1, panicle length, grain yield, straw yield and growth duration decreased with delaying of planting dates. The intermediate short stature plant type of Chinigura exhibited higher number of panicles (300-331 m-2) and comparatively heavier individual grain (12.25-12.31 g), consequently gave higher grain yield (2.79-3.53 t ha-1 ) planted with in December. However, in late planted situation in 10 January Kalijira exhibited higher number of panicles, grains panicle-1, resulted higher grain yield than the rest of the varieties. Thus, cultivation of traditional aromatic fine rice Chinigura and Kalijira have the potentiality to produced higher grain yield when planted in early December in Boro season.
