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.

A series of on-farm fi eld experiments were conducted in two locations in Padang, Koto Panjang and Koto Tingga, West Sumatera, Indonesia in 2015. The purpose of the experiment was to establish the formula of organic fertilizer derived from Tithonia supplied with micro nutrients, Zn and Mn, on rice. The experiments were conducted using completely-randomized block design with six treatments and three replications. The treatments were P = Tithonia Organic Fertilizer Plus (TOFP) + 3.0 kg Mn.ha-1, Q = TOFP + 3.0 kg Mn.ha-1+ 3.0 kg Zn.ha-1, R = TOFP + 4.5 kg Mn.ha-1 + 6 kg Zn.ha-1, S= TOFP + 4.5 kg Mn.ha-1+ 9 kg Zn.ha-1, T = TOFP only, U = 100% chemical fertilizer only. Treatment with micro nutrients as addition to TOFP (TOFP+ 3.0 kg Mn.ha-1 and TOFP+ 3.0 kg Mn.ha-1+3.0 kg Zn.ha-1) increased rice grain yield by 80 g per clump.

Abstract Energy variety of amaranth (Amaranthus spp.) was grown in large-scale trials in order to verify the capability of its cultivation and use as a renewable energy source in a biogas plant. The possibility of biogas production using anaerobic co-fermentation of manure and amaranth silage was verified in the experimental horizontal fermentor of 5 m3 volume, working at mesophilic conditions of 38-40 °C. The goal of the work was also to identify the optimum conditions for growth, harvesting and preservation of amaranth biomass, to optimize biogas production process, and to test the residual slurry from digestion process as a high quality organic fertilizer. The average yield of green amaranth biomass was 51.66 t.ha-1 with dry matter content of 37%. Based on the reached results it can be concluded that amaranth silage, solely or together with another organic materials of agricultural origin, is a suitable raw material for biogas production.

<p>Objetivou-se com o presente trabalho avaliar as características morfométricas e de rendimento da palma forrageira 'Gigante' submetida a diferentes tipos de adubação orgânica, química e organomineral e configurações de plantio<em>. </em>O experimento foi instalado em LATOSSOLO Vermelho-Amarelo distrófico, num delineamento em blocos casualizados, em esquema de parcelas subdivididas, com três repetições. As parcelas constituídas por duas configurações de plantio: 1) 24.0000 plantas ha<sup>-1</sup>, dispostas em fileira tripla, no espaçamento 3,00 x 1,00 x 0,25 m; 2) 26.666 plantas ha<sup>-1</sup>, dispostas em fileira quádrupla, no espaçamento 3,00 x 1,00 x 0,25 m; as subparcelas compostas por 12 tipos de adubação orgânica, química e organomineral. Aos 650 DAP mensuraram-se altura da planta, número, comprimento, largura e índice de área de cladódios, produção de matéria verde e seca e teor de matéria seca. As características morfométricas, o teor de matéria seca e a produção de massa verde e matéria seca foram influenciadas pelas adubações (P&lt;0,05), independentemente da configuração utilizada. Das características morfométricas apenas a largura e área do cladódio não foram influenciadas pelas adubações. A ausência de adubação ou apenas 30 Mg ha<sup>-1</sup> ano<sup>-1</sup> de esterco bovino são insuficientes para obter resultados satisfatórios com palma forrageira ‘Gigante’.</p><p><strong><em>Morphometric traits and yield of forage cactus 'Gigante' under different fertilization and planting settings</em></strong></p><p><strong>Abstract</strong><strong>: </strong>The objective of this study was to evaluate the morphometric characteristics and yield of 'Gigante' forage cactus subjected to different types of organic, chemical, and organic mineral fertilizers and planting configurations. 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 Relationship

A 2-yr study was conducted at Elora and Brucefield, Ont. to examine the relationship between grain yield following grain physiological maturity and whole-plant dry matter (DM) yield and quality determined at the stage desirable for ensiling. Quality parameters analyzed include in vitro dry matter digestibility (IVD) of the stover, IVD of the whole plant, stover lignin content and stover protein content. There was a significant linear relationship between the performance of hybrids for grain yield production and their yield for silage production. However, the relationship was not complete enough to permit reliable selection of hybrids for silage production based on grain yield performance (coefficients of determination were 0.23 and 0.25 for Elora and Brucefield, respectively). Grain dry matter content, however, provided a satisfactory estimate of whole-plant maturity for silage production. Coefficients of determination between grain DM content and whole-plant DM content were 0.71 and 0.53 for Elora and Brucefield, respectively. There was considerable variation among hybrids for lignin content and IVD of stover. Differences were much less for whole-plant IVD. The findings of this study support the need for separate evaluation trials for corn grown for whole-plant silage production as opposed to grain production.Key words: Zea mays, corn silage, grain yield, hybrid performance

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.
