Alley cropping or hedgerow intercropping is one of the many sub-systems of agroforestry technology. A 5 x 3 factorial experiment in a Randomized Complete Block Design (RCBD) with three replications was used to determine the effect of four alley woody species and three plantain cultivars on the yield of ITA 331 upland rice grain in the 2017 and 2018 farming seasons. The Alley species, plantain  cultivars and Alley species x plantain cultivars treatment interactions showed no significant effects (p>0.05) on ITA 331 upland rice grain yield. Student t-test on the two farming seasons showed significant increase in yield of ITA 331 upland rice grain in 2018 than in 2017. The non-significantly different rice grain yield in the alley species treatment plots could be due to the generally high nutrient release of the decomposed legume-based alley species. Agroforestry combination of alley plants species and plantain cultivars is suitable for ITA 331 upland rice production. Key words: alley cropping, yield, ITA 331 upland rice grain, alley woody species, plantain cultivars

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.

For upland rice, it is desired, among many objectives, to obtain highly productive and early genotypes, consequently reducing the risk of establishing a crop regarding climatic adversities. Therefore, this study aimed to verify the correlation between the agronomic traits days to flowering and grain yield of 14 upland rice lines. The experiment was conducted in seven environments, in the 2013/14, 2014/15 and 2015/16 crop years, in a randomized complete block design with three replications. Both the genotypic and phenotypic correlation were significant and positive, whereas the genotype correlation was superior to the phenotype. However, it was noted a low magnitude of the correlation values. It was concluded that a favorable and simultaneous selection is possible for high grain yield and plants with early blossoming cycle in upland rice.

The aim of the present study was to compare the selection performed by the sum of standardized variables index (Z Index) with the selection based only on the grain yield character, to verify if the grain yield alone is a good alternative for the selection involving multiple characters. The experiments were conducted in Lavras-MG and in Lambari-MG, during the 2015/2016 agricultural year. The used design was the randomized complete block design with 3 replications. Thirty-six genotypes of the preliminary trial of upland rice breeding program of the Federal University of Lavras were evaluated. In order to compose the Z index, the following characteristics were evaluated: grain yield, height, number of days for flowering, 1000-grain weight, income, yield, leaf blast incidence, and grain length/width ratio. Z index was efficient in the selection for multiple characters whereas not all lines with the highest grain yield obtained good results in the other desirable characteristics, indicating that the selection based only on grain yield is not efficient when working with several characters of interest in upland rice cultivation.

The research was conducted in Tamanbogo Station Research in the 2007 Rainy Season in upland rice-corn intercropping farming. The research design used Randomized Complete Block Design with 3 replications. The treatments were 1). 15 t ha-1 manures + Residues of rock phosphate (RRP),  2). Without manures + RRP, 3). 15 t ha-1 manures + 150 kg  ha-1 SP 36 and  4). Without manures + 150 kg ha-1 SP 36. The upland rice was seeded in planting space of 25 cm x 25 cm, 2-3 seeds/hill. The land was treated with 1 t ha-1 of RP in the last farming year while SP36 was applicated each season. Urea and KCl fertilizers that were used on upland rice were 300 kg ha-1 and 100 kg ha-1, respectively while corns were fertilized with 250 kg ha-1 urea and 100 kg KCl ha-1. The research results showed that the availability of N and K nutrients in the soil at the time of before planting was low but the availability P was high. Application of manures and RRP increased C-organic, availability of P , Ca and  Cation Exchangeable Capacity in the soil. Application of 15 t ha-1 of manures with RRP increased dry biomass weight of rice and corn, there were 45.17 % and 49.23 %, respectively. The grain yield of rice and corn on the treatment of manures and RRP were not gave significant different compare to the yield was gained with SP 36  fertilizer.

Abstract The objective of this work was to determine the effects of soil compaction pressure on the sowing furrow and of seed treatments with insecticides on grain yield and on termite damage in upland rice plants under no-tillage, in the Center West region of Brazil. Three experiments were carried out, consisting of five seed treatments combined with three (first experiment) or four (second and third experiments) compaction pressures in a randomized complete block design, in a factorial arrangement. The seed treatments were: T0, without treatment; T1, imidacloprid+thiodicarb; T2, thiamethoxam; T3, carbofuran; and T4, fipronil+pyraclostrobin+thiophanate-methyl. The compaction pressures applied were: 25, 42, and 268 kPa, in the first experiment; and these same pressures plus 126 kPa in the second and third experiments. Seed treatment was effective in increasing rice grain yield, from 1,753 to 4,141 kg ha-1, especially in the lowest compaction pressure of 25 kPa. Soil compaction around 180 kPa in the sowing furrow results in higher rice grain yield and in fewer stems killed by termites. The use of soil compaction on the sowing furrow with seed treatment significantly increases rice grain yield under a no-tillage system.

Abstract: The objective of this work was to evaluate the efficiency of molten and ground alkaline potassium-silicate rocks (K1) and of ground phonolite rock (K2) as sources of potassium for upland rice (Oryza sativa) and common bean (Phaseolus vulgaris) crops, in comparison with the traditional source (KCl). Two experiments - one with each crop - were conducted on a Typic Haplorthox in a randomized complete block design with four replicates. The treatments consisted of three sources (KCl, K1, and K2) and four rates (0, 20, 40, and 80 kg ha-1 K2O) of K. Regardless of the used source, K fertilization increased the leaf K content and grain yield of the upland rice and common bean crops. The agronomic efficiency index (AEI) of the alternative K sources varied according to the crop. For upland rice, the AEI of K2 was 8% higher than that of KCl at the recommended K rate, but similar at the highest rate. For common bean, the AEI values of K1 were close to that of KCl at the rates of 40 and 80 kg ha-1 K2O. The alternative sources K1 and K2 supply K and increase the grain yield of common bean and upland rice, respectively, similarly to KCl.

AbstractAn experiment was conducted at Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, to find out the effect ofdhainchaincorporation on subsequent rice crop yield and postharvest soil nutrient status. The experiment was laid out in a randomized complete block design having three replications. Ninedhainchaaccessions were used as experimental materials along with a control (withoutdhainchaplant). Seeds ofdhainchaaccessions were sown in experimental plot @ 60 kg ha−1. Sixty days olddhainchaplants were mixed up with soil. Soil samples were collected twice, before sowing ofdhainchaseeds and after rice crop harvest. Forty five days old healthy rice seedlings were transplanted in the well prepareddhainchaincorporated plots at the spacing of 15 cm x 25 cm (plant-plant x row-row). The pH and nutrient status were improved indhainchaincorporated soil over the control. The highest grain yield (5.81 t ha−1) was obtained fromdhainchaAcc. 33 incorporated plot followed by Acc. 25 (5.73 t ha−1) and the lowest in control (4.35 t ha−1). Due to the incorporation ofdhainchabiomass in soil, the rice grain yield increased 7.82% to 33.56% over the control. Among thedhainchaaccessions, number 33 showed the best performance in terms of influencing grain yield. A precise conclusion to be built up through collection of large number of germplasms from Bangladesh is needed.

ABSTRACT To achieve an accurate phenotyping for drought tolerance, it is important to control water stress levels and timing. This study aimed to determine water use by upland rice plants during periods of irrigation withholding and its relationship with grain yield in order to increase the efficiency of this phenotyping. Two experiments were carried out in a randomized block design in which six water treatments (irrigation withholding for periods of 2, 4, 6, 8, 10 and 12 days) were compared, with four replicates. In the first experiment, treatments were applied at the R3 stage (panicle exsertion) and, in the second, at the R5 stage (beginning of grain filling). The amount of water evapotranspired was determined by the difference between the soil water storage at the beginning and at the end of irrigation withholding periods, from the surface to 80-cm depth. Evapotranspiration of upland rice from R3 stage was higher compared to that observed from R5 stage, when subjected to similar irrigation withholding periods in both growth stages. Rice grain yield is more sensitive to irrigation withholding imposed from R5 stage than from R3 stage.
