There is a growing interest in fast-growing hybrid poplar and willow plantations in Canada. This interest can be explained both by the rapid growth rate and high yield potential of this type of production system. However, their establishment and maintenance require considerable investments. Research efforts on productivity comparisons between different clones or species, breeding, physiology, nutrition, silviculture, pest management, harvesting methods, social and economic issues and industrial transformation contribute to maximizing fibre production and minimizing production costs. The objective of this paper is to briefly describe a number of current or recently completed research studies on fast-growing hybrid poplar and willow plantations and to discuss their utility and impacts for practical applications.

Cultivation of true shallot seeds has the potential to be developed in Indonesia because apart from being able to reduce the cost of providing seeds, it also has higher productivity than shallot from tubers. This study aims to determine the appearance of true shallot seed varieties that have high yield potential in the highlands of West Sumatra. The study used a randomized complete block design (RCBD) with 4 treatments of true shallot seed varieties, namely, Trisula, Bima, Lokananta, and Sanren, with 6 replications. The results showed that except for the age of harvest and the number of tubers per hill, the treatment of various varieties of true shallot seeds showed a significant effect on all observed variables. Lokananta variety has better growth component, yield component, and yields compared to other varieties (Trisula, Bima, and Sanren). Cultivation of true shallot seeds in the highlands gives lower yields than in the adapted area (lowland), except for the Trisula variety. Lokananta variety is recommended for use in the highlands of West Sumatra.

Switchgrass (Panicum virgatum L.) is a herbaceous perennial grass that can be used as bedding for livestock, planted in buffer strips, and used as biofuel, but it is still not widely grown in eastern Canada. The objectives of this study were to verify the performance of the Integrated Farm System Model (IFSM) in simulating switchgrass growth and to estimate its yield potential and production costs in eastern Canada. The performance of IFSM was assessed with dry matter (DM) yield of switchgrass (‘Cave-in-Rock’) measured over three growing seasons (2015–2017) in southern Quebec, Canada. The model performed reasonably well, with normalized root mean square errors of 19.5% for calibration and 27.9% for validation. Simulation results of potential yield and economic management over the long term (1986–2015) for five switchgrass production sites in eastern Canada indicated that average DM yields in Quebec City and Fredericton (9.6 and 9.7 t ha−1, respectively) were significantly lower than average DM yields in Saint-Hubert, Ottawa, and London (10.8, 10.4, and 11.0 t ha−1, respectively). Average annual production costs per tonne of DM for the spring harvest were higher at low-yield sites (CAD$66.67 and $64.50 for Fredericton and Quebec City, respectively) than at high-yield sites ($60.10, $62.82, and $60.08 for Saint-Hubert, Ottawa, and London, respectively). The IFSM-estimated production costs were within the range of the calculated values reported in other agro-economic analyses conducted in Ontario and Quebec.

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.

Two experiments were conducted at (i) irrigated lowland, village of Bojong, Cikembar, Sukabumi Sub-district, Indonesia, from November 2011 to February 2012, and (ii) rain-fed lowland, village of Sanca, Gantar sub-district, Indramayu, Indonesia, from April to July 2012. The objective of the experiment was to determine the yield of drought-tolerant hybrid rice genotypes. A randomized block design with three replications was used. The treatment consisted of 8 hybrid rice genotypes (BI485A/BP3, BI485A/BP5, BI485A/BP10, BI485A/BP12, BI485A/BP15, BI599A/BP5, BI599A/BP15 and BI665A/BP6) and 2 check varieties (Hipa 7 and Ciherang) for the experiment in irrigated lowland, 4 hybrid genotypes (BI485A/BP3, BI485A/BP12, BI485A/BP15 and BI599A/BP15) and 3 check varieties (Hipa 7, IR64 and Limboto) for the experiment in rain-fed lowland. On irrigated lowland, all tested-genotypes produced grain yield per hectare, which was not significantly different from the check varieties Ciherang and HIPA 7. The yield of genotype BI485A/BP12, BI485A/BP15 and BI559A/BP15 under irrigated lowland showed non-significant different with check varieties Ciherang and Hipa 7, i.e 5.63, 6.87, and 6.30 tons ha-1, respectively. Genotype BI599A/BP15 under severe drought rain-fed lowland yielded 0.90 tons of grain ha-1, whereas Hipa 7 (hybrid variety, suitable for rain-fed lowland) and Limboto (drought-tolerant check variety) reached 0.34 and 0.29 tons ha-1, respectively. Genotype BI599A/BP15 is a new hybrid genotype that potential for advanced development in rain-fed lowland and in irrigated lowland with a high yield potential and quiet early-maturity age.

Mineral Fertilization

In general, fertilization recommendations for pepper are old and scarce. Because pepper is a semi-perennial crop with high yield potential and dependence on phosphorus (P), an extremely important element, as it participates in several metabolic processes, it is necessary to look for efficient alternatives for phosphatefertilization, due to its low availability and high adsorption capacity in most Brazilian soils. Slow-release fertilizers have been shown to be an excellent alternative to conventional mineral fertilization. Therefore, the objective of this study was to evaluate the effect of different sources of P on growth and yield of hot pepper (Capsicum frutescens L.). An experiment was carried out in a greenhouse in the JK campus of UFVJM, Diamantina -MG, Brazil, arranged in a completely randomized design with eleven treataments(absence of fertilization, mineral treatment, organic treatment and four slow-release phosphate sources: pelleted organomineral, granulated organomineral, MAP coated and triple formulated, at doses of 150 and 300 kg ha-1 of P2O5). Growth variables, fresh and dry matter accumulation and yield were evaluated 180 days after planting. The pelleted and granulated organomineral treatments at the dose of 300 kg ha-1 of P2O5,promoted the best results for the parameters dry mass of root, number of fruits per plant, fresh and dry mass of fruits and total yield. Such results can be explained by the better efficiency of P release and the better absorptionof this nutrient by the plant, making it an excellent option in relation to conventional sources commonly adopted.

The experiment was conducted at the Bangladesh Rice Research Institute Farm, Gazipur, in Boro season. BasmatiPNR, Basmati370, Basmati375 and Basmati-D were transplanted started from 10 December, and continued up to 25 January in the following year, at an interval of 15 days. Forty day old seedlings were transplanted spaced at 20 cm × 15 cm, to find out the optimum planting time and to select the Basmati varieties having high yield potential. The tallness of plants, number of tillers and dry matter were increased with the advancement of planting dates. On the country, number of panicles, grains panicle-1, panicle length, grain yield and growth duration decreased as delayed planting dates. The short stature BasmatiPNR and tall plant of Basmati375 exhibited higher number of panicles, grains panicle-1 and heavier individual grain which contributed to increase grain yield. Thus, high yield potential varieties BasmatiPNR and Basmati375 to be planted in optimum time on 10 December, to obtain maximum grain yield of rice in Boro season.  DOI: http://dx.doi.org/10.3329/jsf.v11i2.21594  Journal of Science Foundation, 2013;11(2):37-42

Field-based experiments were conducted during wheat cultivation seasons of 2017–2018 and 2018–2019 to minimize the impact of hidden hunger (micronutrient deficiencies) through agronomic biofortification of two wheat cultivars with zinc and iron. Two spring-planted bread wheat cultivars: Zincol-16 (Zn-efficient) and Anaj-17 (Zn-inefficient with high-yield potential) were treated with either zinc (10 kg/ha), iron (12 kg/ha), or their combination to study their effect on some growth attributes (plant height, tillers, and spike length, etc.,), productivity, and quality. No application of zinc and iron or their combinations served as the control. Maximum Zn and Fe contents of grains were improved by sole application of Zn and Fe, respectively. A higher concentration of Ca in grains was observed by the combined application of Zn and Fe. Starch contents were found maximum by sole application of Fe. Sole or combined application of Zn and Fe reduced wet gluten contents. Maximum proteins were recorded in Anaj-17 under control treatments. Zincol-16 produced maximum ionic concentration, starch contents, and wet gluten as compared to Anaj-17. Yield and growth attributes were also significantly (p < 0.05) improved by combined application as compared to the sole application of Zn or Fe. The combined application also produced the highest biological and grain yield with a maximum harvest index. Cultivar Anaj-17 was found more responsive regarding growth and yield attributes comparatively. The findings of the present study showed that the combined application of Zn and Fe produced good quality grains (more Zn, Fe, Ca, starch, and less gluten concentrations) with a maximum productivity of bread wheat cultivars.

Abstract: The objective of this work was to evaluate the relationship between grain yield and production costs of flood-irrigated rice (Oryza sativa) in the state of Rio Grande do Sul, Brazil, in order to determine the yield range that maximizes the profit of farmers. There are estimations pointing out that the yield range that maximizes the profit for farmers is about 75 and 85% of the yield potential; however, this still needs to be validated for irrigated rice in Brazil. To validate these values, a technical and economic monitoring was carried out for eight farmers of irrigated rice, whose production costs were measured and compared with the mean yield and the percentage of potential yield achieved. To determine the potential yield of each crop, SimulArroz, a process-based model developed for the simulation of rice growth and yield in the South of Brazil, was used. The grain yield achieved by the farmers ranged from 6.3 to 11.0 Mg ha-1 (48 to 83% of the potential yield), costs ranged from R$4,197.00 ha-1 to R$6,227.00 ha-1, and profit ranged from R$-52.00 ha-1 to R$3,599.00 ha-1. Farmers who reach between 69 and 83% of yield potential achieve the highest profitability. The investment planning based on the yield potential calculated by the SimulArroz model can be efficiently adopted for irrigated rice crops.

In order to establish the pure line of sponge gourd containing aroma feature, we selected the desirable inbred lines by using a self-pollinating method. The present study was investigated to estimate the morphological traits and fruit quality of 6 sponge gourd inbred lines which generated at 4th generation of an aroma Luffa accession B29 under plastic house conditions. The experiment was conducted in a randomized complete block design (RCBD) with three replications, from May to November in 2016. Five plants per replication were examined. The results indicated that all inbred lines could grow well under plastic house conditions. The inbred lines had the same stem and leaf traits; whereas fruit shape, skin color and fruit veins color were observed differently among inbred lines. The aromatic trait was retained in all inbred lines either before or after cooking. The high yield was found in lines BC1 and BC2 by 10.1 tons/ha and 10.7 tons/ha, respectively. These inbred lines should be examined in open field condition to confirm the presence of aromatic trait and yield potential before completion of the procedures for recognition of new Luffa varieties.
