 This study aimed to evaluate the structural, productive and nutritional characteristics of cactus pear (Nopalea cochenillifera Salm Dyck. cv. Miúda/Doce) under five nitrogen doses and two planting orientations. A randomized block design in a 5 x 2 factorial scheme was used in the scheme: five nitrogen doses (0, 150, 300, 450 and 600 kg of N ha-1), and two planting orientations (North/South and East/West), with three replicates. Except for the thickness of the secondary (p = 0.04) and tertiary cladodes (p = 0.02), the morphometric characteristics of the cactus pear were not influenced by the nitrogen doses (p > 0.05). The mean height was 120 cm, the areas of the primary, secondary and tertiary cladodium were 160.9; 208 and 158.4 cm², respectively. The application of nitrogen fertilizer, in the dry conditions and doses evaluated, did not affect the production of green matter (PGM, p = 0.56), dry matter (PDM, p = 0.74) and dry matter content (DM, p = 0.72), with averages of 276 t ha-1, 43.2 t ha-1 and 15.7%, respectively. The increase of the nitrogen doses does not improve the majority of the morphometric characteristics or the dry matter yield of the cactus pear cv. Miúda at 730 days after planting.

The experiment was installed in a dystrophic Red-Yellow LATOSOL (Oxisol), in a randomized block design, in a split plot design parcel, with three replications. The plots consist of two plant configurations: 1) 24.0000 pl ha<sup>-1</sup>, arranged in triple row, spaced 3.00 x 1.00 x 0.25 m; 2) 26,666 pl ha<sup>-1</sup>, arranged in quadruple row, spaced 3.00 x 1.00 x 0.25 m. The subplots are composed of types of organic, chemical, and organic mineral fertilizers. On the 650th DAP were measured the plant height, number, length, width, cladode area index, fresh and dry matter yield and dry matter content. Morphometric characteristics, the dry matter content and the green mass and dry matter production were influenced by fertilization (P &lt;0.05), regardless the configuration. From the morphometric features, only the width and cladode area were not affected by fertilization. The absence of fertilization or just 30 Mg ha<sup>-1</sup> yr<sup>-1</sup> of cattle manure is not enough to achieve satisfactory results with 'Gigante' forage cactus.</p>

The objective of this study was to evaluate the production and chemical composition of silages of grass Tanzania and corn, grown single or intercropping. The experiment was conducted at UTFPR Câmpus Dois Vizinhos in the period between October 2011 and July 2012, a 600 m² area. The treatments were: TMI - single corn, TMT - corn and grass Tanzania consortium at the time of sowing, TT - Tanzania grass single, TT32 - grass Tanzania silage to 32% dry matter (content similar to that of corn). The experimental design a randomized block design with four treatments and five replications. Agronomic evaluations were performed 120 days after planting, as follows: number of linear-1 plants metro, plant height and ear insertion and number of ears.plants-1. In the grass we evaluated canopy height, where it was held the botanical separation in green leaves, dried and stem. Silage started being held in 100 mm PVC pipe (mini-silos) kept sealed for 60 days. At the time of opening of the silo were determined the following parameters: DM, pH, total loss of DM (PDM), specifies mass (SM), dry matter recovery indices (IRDM), losses gas (LG), and size particle. Chemical analysis of the results of OM, MM, ADF were higher for TMI treatments, TT and TT, respectively. CP and LIG had superior results for the treatments containing grass. Corn intercropping with grass Tanzania silage provides more crude protein and lignin compared to exclusive corn silage without damaging the crop yield. Silage maiden Tanzania has higher levels of ADF and crude protein as well as increased production of dry matter than corn silage. The grass Tanzania should be harvested with 30% DM as presented better pH values, higher dry matter recovery rate, less loss of gas as well as increased production of dry matter that Tanzania harvested at the same age corn.

AbstractA field experiment was conducted in the central highlands of Ethiopia to evaluate the performance of potato varieties for tuber yield and to identify a superior variety in tuber yield and yield components. The experiment was laid out in a randomized complete block design with three replications at two locations in the central highlands of Ethiopia during the 2017 main cropping season. The results of analysis of variance (ANOVA) showed the presence of highly significant (P<0.01) differences among varieties over all traits studied. The mean squares for location were also significant in indicating the influence of environments on the traits of the studied varieties. However, the interaction between variety and environment had no significant effect on the performances of the potato varieties to attain 50% flowering, specific gravity and dry matter content indicating a similar performance of these traits across all locations. The variety Belete produced the maximum total tuber yield of 32.8 t ha -1 and marketable tuber yield of 29.1 t ha-1. Conversely, farmers` variety Nech Abeba produced the minimum total tuber yield of 13.8 t ha-1 and marketable tuber yield of 8.4 t ha-1. For most tuber quality traits, viz., tuber specific gravity, dry matter content, starch percentage and total starch yield, varieties Belete and Menagesha were the maximum and minimum producers, respectively. Thus, it could be concluded that varietal and environmental variations as well as their interaction had considerable influence on tuber yield and the potato’s attributes.

Irrigation is a prerequisite for economical onion production under dry conditions. However, its effect on dry matter and nutrient content often remains a concern for growers. A direct sown onion hybrid was grown under open field, rain-fed and irrigated conditions for three years, investigating the effects of air temperature and water supply on some nutritive constituents. Dry matter, storage sugar, total flavonol and total polyphenol content showed strong positive correlation with average air temperature and negative correlation with water supply. However, irrigation had a positive effect on storage sugar and dry matter content. Presumably better water supply during dry periods ensured by irrigation provided the basis for higher photosynthetic production, and hereby more dry matter partitioning and accumulation in the bulb, a storage organ. An unexpected decrease in vitamin C content was experienced in 2011 and 2012, compared to the result of 2010, which was explained by the hot and dry conditions of the pre-harvest irrigation cut-off period. Fibre and ash content was found to be the most stable nutritional characteristics, affected neither by the environmental conditions, nor by the irrigation. Irrigation has proved to be very beneficial for direct sown onion, doubling bulb yield while not affecting the nutritive quality negatively.

ABSTRACT The objective was to evaluate the effect of different spacings and mineral fertilizations on cactus pear growth and production in a randomized block design, with three replicates, in a 3 x 4 factorial scheme: three spacings, 1.00 x 0.50 m, 2.00 x 0.25 m and 3.00 x 1.00 x 0.25 m, and four fertilizations, 000-000-000, 000-150-000, 200-150-000 and 200-150-100 kg ha-1 of N, P2O5 and K2O, respectively. Plant growth was evaluated between 90 and 390 days and production and growth were evaluated at 620 days after planting. There were significant interactions between spacing and fertilization for plant height, number of cladodes and cladode area index from 90 to 390 days and for production of fresh and dry matter at 620 days after planting. Spacing influenced cladode area index, while fertilization influenced plant height, number of cladodes and cladode area index at 620 days after planting. Plant height showed cubic effect for the days after planting. Number of cladodes and cladode area index were dependent on spacing, fertilization and plant age, and fitted to cubic models. The best results of growth and production of fresh and dry matter are associated with NPK and NP fertilizations and the spacing of 1.00 x 0.50 m.

The paper records the results of an investigation into the composition, digestibility and nutritive value of marrow stem kale (both unthinned and singled-out) and thousand head kale. A number of the main findings are recorded below.The average dry-matter content of unthinned marrow stem kale during September and October was 13·3 per cent. During the following January it had reached a slightly higher level, namely, 14·2 per cent. Singling out of the marrow stem kale appeared to exercise little effect on the dry-matter content of the crop. Thousand head kale, with an average dry-matter content of 15·8 per cent., is significantly richer in dry matter than the marrow stem kale, although this advantage was offset by the lower yield, in terms of green matter, given per acre by the thousand head kale.

This study assessed variability, heritability and correlations of agronomic traits in an onion (Allium cepa L.) landrace and derived S1lines after a single selfing generation. Bulbs used to develop S1lines were selected for shape, colour and high number of skins. Fifty-one S1lines and the original population were evaluated using an incomplete random block design. The original population and S1lines were highly diverse for quantitative and qualitative traits. S1lines were significantly different, with transgressive segregation for number and maximum leaf length, bulbing index, bulb weight, diameter, and dry matter content. Variances within S1lines were greater than among S1lines for all traits. Bulb colour and number of skins responded to selection. Heritabilities for dry matter and soluble solids were 52.6% and 36.1% respectively. Both traits were highly correlated. The development of S1lines allowed the expression of genetic variation and the identification of better genotypes for agronomic traits of interest.

A field experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, Dhaka. During the period from October, 2018 to March, 2019 to find out the growth and yield of onion as influenced by Sulphur and Boron with mulch materials. The experiment consisted of two factors: Factor A: Four doses of Sulphurand Boron fertilizer viz. F0 = S0kgB0kg/ha (Control), F1 = S20kgB1kg/ha, F2 = S40kgB2kg/ha, F3 = S60kgB3kg/ha and Factor B: Four types of mulch viz. M0 = No mulch and no irrigation, M1 = Black polythene, M2 = Water hyacinth and M3 = Rice straw. There were 16 treatment combinations and experiment was setup in a Randomized Complete Block Design (RCBD) with three replications. In case of Sulphur and Boron treatments at 60 days after transplanting (DAT), the highest plant height 53.38 cm, maximum leaf number 10.48, highest bulb length 4.83 cm,, maximum neck diameter (1.31 cm), highest dry matter content (15.98%), dry matter content of leaf (24.74%), single bulb weight (39.93 g), yield per plot (0.80 kg) and yield per hectare (9.98 t) were obtained from F3 treatment. Among the mulch materials,  highest plant height at 60 DAT (52.51 cm), maximum leaf number (10.19), highest bulb length (4.52 cm), highest bulb diameter (5.74 cm), maximum neck diameter (1.26 cm), dry matter content of leaf (23.35%), single bulb weight (39.05 g), yield per plot (0.78 kg) and yield per hectare (9.76 t) were obtained from M1 treatment. In combined effect, the highest plant height at 60 DAT (55.54 cm), maximum leaf number (11.47), longest bulb length (5.51 cm), highest bulb diameter (6.68 cm), maximum diameter of neck (1.42 cm), dry matter content of leaf (27.48%), single bulb weight (42.40 g), yield per plot (0.85 kg) and yield per hectare (11.21 t) were obtained from F3M1 treatment (S60kg/ha + B3kg/ha with black polythene mulch). The highest gross return (Tk. 3, 36, 300/ha), net return (Tk. 1, 88, 934/ha) and benefit cost ration (2.28) was obtained from the treatment combination (F3M1). Accordingly, for high growth, high yield, and economic point of view, F3M1 treatment is recommended in onion cultivation.

Abstract This study evaluated dry matter yield and nutritional characteristics of different oat genotypes (Avena spp.) for ensiling. Treatments consisted of genotypes of white oat IPR 126 (Avena sativa), black oat Cabocla IPR and Agrocoxilha (Avena strigosa), and BRS Madrugada and BRS Centauro (Avena vertis). Oats were harvested at the phenological stage of milk/dough grain. The design was a completely randomized block scheme, with five treatments and three replications per treatment. The IPR Cabocla genotype showed the highest dry matter content (before and after silo opening) and in vitro dry matter digestibility of fresh forage. No differences were observed for in vitro dry matter digestibility and dry matter losses among silages. The highest silage digestible dry matter yield (kg ha-1) was observed for the BRS Centauro genotype. Thus, despite the better nutritional quality presented by the IPR Cabocla genotype before ensiling, BRS Centauro genotype presented a higher yield of digestible dry matter per hectare.
