A 3 x 3 factorial experiment laid out in a randomized complete block design was conducted at Nsukka, Nigeria to determine the effects of cutting height and N fertilizer application on the extent of plant cover and percentage dry matter of Panicum maximum pasture in 2008 and 2009. Treatments comprised three cutting heights of 5, 10 and 15 cm and three levels of nitrogen of 0, 200 and 400 kg N ha‐1 resulting in nine treatment combinations replicated three times. The extent of grass cover in 2008 and 2009 was significantly (P < 0.05) increased by 62 % and 46 %, respectively, when cutting height increased from 5 to 15 cm. Bare ground area was significantly (P < 0.05) decreased by 33 % in 2008, when stubble height increased from 5 to 15 cm but was not significantly affected by cutting height in 2009. The extent of weed cover was not significantly influenced by cutting height in both years. Grass cover was significantly (P < 0.05) increased by 36 % in 2008 when nitrogen fertilizer was increased from 0 to 200 kg N ha‐1. Nitrogen application did not significantly affect the weed cover and bare ground area in both years. The dry matter content of grass was significantly (P < 0.05) decreased by 11 % and 17 % in 2008 and 2009, respectively, when fertilizer N was increased from 0 to 400 kg N ha‐1.

The purpose of this study is to determine the appropriate level of chicken manure for the green fodder M. oleifera grown for leaf meal production as a supplement into poultry diet to improve poultry product quality (i.e., meat and egg). The experiment was conducted at Thai Nguyen University of Agriculture and Forestry, Vietnam, for two years from 2018 to 2019. The experiment consisted of four treatments (NT) represented by four different levels of chicken manure, namely, 0 tons (NT1), 10 tons (NT2), 20 tons (NT3) and 30 tons/ha/yr (NT4). Each treatment was carried out over an area of 24 m2 with 5 replicates. The experiment was the complete randomised block design. Other factors such as plantation density, nitrogen, phosphate, potassium fertiliser levels, cutting height, and cutting intervals, etc., were similar among treatments. The results showed that the leaf dry matter yield of NT1 through NT4 was 6.919, 8.131, 8.975, and 9.494 tons/ha/yr, respectively. That of the leaf crude protein was 2.244, 2.694, 3.073, and 3.357 tons/ha/yr, respectively. Increasing manure levels from 0 to 30 tons/ha/yr decreased the dry matter content in the leaves by 1.43%, increased the crude protein in leaf dry matter basic by 2.93%, and decreased crude fibre in the leaf dry matter basic by 2.24%. Based on these results and data from statistical analysis, the most appropriate level of chicken manure application for M. oleifera was at 20 tons/ha/yr.

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.

Cutting Height

The goal of this study was to assess the dehydration curve and nutritional value of Tifton 85 bermudagrass at two cutting heights from ground level (4 and 8 cm) during 120 days of storage in a closed shed. The dehydration curve was determined using samples from the entire plant at eight different times. The experimental design consisted of randomized blocks with plots subdivided per times and five replicates. The second step consisted of assessing the nutritional value of the stored Tifton 85 bermudagrass in randomized blocks with plots subdivided per times and two treatments per plot: cutting height of four and eight centimeters from the ground, and five different times for the subplots, with five replicates. Dehydration of Tifton 85 bermudagrass at the two heights occurred in 48 hours, considered an ideal time for hay drying. The dry matter content responded quadratically to the time of storage of the two heights, only differing during baling and after 120 days of storage. Crude protein content had a quadratic behavior in the two cutting heights, with the smallest value after 30 days of storage (107.0 g kg-1) and the largest after 90 days (147.8 g kg-1) in the cutting height of eight centimeters. The ether extract exhibited a quadratic behavior in the two cutting heights, only differing after 90 days of storage. The neutral detergent fiber content had linear positive response according to the time of storage, with no difference between the cutting heights. For the neutral detergent fiber content in the two cutting heights, the quadratic regression model was the best fit to the data, differing between the heights after 30 and 60 days of storage. In vitro dry matter digestibility and in vitro cell wall digestibility values of the stored hay were lower than the values obtained at the time of cutting. Cutting performed at four centimeters from the ground was the most suitable for hay production due to higher dry matter production and nutritional value without difference between bailing treatments. Hay storage caused undesirable changes in the nutritional value, especially in fiber content and in vitro digestibility.

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>

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.

The effect of harvest period on the quality of storage roots and leaves of cassava cultivars was determined in an experiment carried out in a randomized complete block design with four replications in a split plot scheme, with five cultivars in the plots and ten harvest times in the subplots. The IAC 13 cultivar had the highest rate of dry matter accumulation in the storage roots and the Mico cultivar the lowest. The period of least dry matter content in the storage roots occurred later for the Fécula Branca, Mico and IAC 14 cultivars, and the minimum starch content in the storage roots occurred later for the Fécula Branca and Mico cultivars. In general, the IAC 13, IAC 14 and Fécula Branca cultivars had higher dry matter content in the storage roots, while higher starch content in the dry and fresh matter were obtained in the Fécula Branca cultivar. The crude protein content in the leaves decreased as the plant aged.

A field experiment was carried out at research field, College of Horticulture, Mandsaur (M.P.) during kharif season, 2018-19. Twenty treatment combinations comprising of four dates of sowing (D1 - 20th July, D2 - 5th August, D3 - 20th August and D4 - 5th September) and five varieties (V1 - Arka Vijay, V2 - Konkan Bhushan, V3 - Arka Visthar, V4 - Arka Adarsh and V5 - Arka Prasidhi) were evaluated in factorial randomized block design with three replications. The findings of the investigation revealed that among the dates of sowing, D1 (20th July) recorded significantly higher growth parameters, yield parameters and yield. There was highest protein content, dry matter content and fibre content in edible pods under D1 (20th July) and lowest with D4 (5th September) date of sowing. Earliest first flowering, 50% flowering and first picking of pod was noted with D4 (5th September) date of sowing. Among the varieties, variety V3 (Arka Visthar) showed superiority for growth parameters and yield parameters viz., number of spikes plant-1(116.21), pod width (23.04mm), weight of 10 pods (96.19g), pod yield plant-1 (2579.1g), pod yield ha-1 (339.6q) and harvest index (39.4%). Earliest first flowering (41.5 days) and first picking (63.7 days) was observed with V2 (Konkan Bhushan). Highest spike length (31.49cm) was measured with variety V2 (Konkan Bhushan). Highest pod length (14.05cm) and number of pods plant-1 (340.6) were recorded with variety V5 (Arka Prasidhi). Highest protein content (2.80%), fibre content (1.94%) and dry matter content (16.20%) were obtained under the variety V1 (Arka Vijay).

The objective of this study was to evaluate the agronomic characteristics, bromatological-chemical composition and digestibility of 11 corn cultivars (Zea mays) harvested at two cutting heights. Cultivars D 766, D 657, D 1000, P 3021, P 3041, C 805, C 333, AG 5011, FO 01, CO 9621 and BR 205 were evaluated when they were harvested 5 cm above ground (low) and 5 cm below the insertion of the first ear (high). The experiment was designed as random blocks, with three replicates, arranged in an 11 x 2 factorial scheme. Cultivars presented similar productions of forage dry matter and grains. Percentages of stalk, leaf, straw, cob and kernel fractions were different among cultivars, as well as dry matter content of the whole plant at harvest. Considering the whole plant, only the contents of gross energy, nitrogen in neutral detergent fiber, and in vitro neutral and acid detergent fiber digestibility did not differ among cultivars. Increase on the cutting height improved forage quality due to the reduction of stalk and leaf fractions and contents of cell wall constituents.
