1. Agroforestry systems and understory harvest management: the impact on growth and productivity of dual-purpose wheat
Abstract: The objective of the study was to evaluate the growth and production efficiency of forage-grain dual-purpose wheat in two arrangements and four agroforestry systems (Intercrop-I and Intercrop-II), as well as to evaluate crop management for the wheat crops in two planting seasons (Crop Season I-2014 and Crop Season II-2015. The experiment was condu

2. Changes in leaf appearance and developmental phases associated with breeding progress in six-rowed barley in the Pannonian Plain
Abstract The aim of this study was to analyze traits of leaf appearance and phenological development related to grain yield gain in winter barley cultivars released over the past 50 years. Field trials with 15 six-rowed winter barley cultivars were conducted during two growing seasons. The main leaf appearance and developmental traits were studied. The durat

3. Cardinal temperatures and modeling of vegetative development in guava
RESUMO O objetivo deste estudo foi estimar as temperaturas cardinais (basal inferior, ótima e basal superior) e simular o desenvolvimento vegetativo da goiabeira através dos modelos filocrono (linear) e Wang e Engel (não linear) durante a fase de muda. Um experimento de campo instalado em Itajubá, MG (22° 24’ 46.43” S 45° 26’ 48.94” O) foi cond

4. CARACTERÍSTICAS MORFOGÊNICAS E ESTRUTURAIS DO SORGO FORRAGEIRO SUBMETIDO A LOTAÇÃO CONTÍNUA COM NOVILHOS DE CORTE SUPLEMENTADOS
Resumo A morfogênese é uma valiosa ferramenta para a compreensão da dinâmica do pasto, porém os estudos morfogênicos referentes à cultura do sorgo ainda são escassos. O objetivo do presente estudo foi avaliar os efeitos de diferentes níveis de suplementação sobre as características morfogênicas do sorgo forrageiro. O experimento foi conduzido na

5. Thermal Requirements and Photoperiod Influence in the Leaf Development of Two Forest Species
ABSTRACT The aim of this work was to evaluate the effect of thermal time methods and to identify the phyllochron and photoperiod response in seedlings of two forest species: Corymbia citriodora and Eucalyptus urophylla. A field experiment was installed under a completely randomized design, in a 2 × 11 factorial scheme, with two forest species and eleven sow

6. Phenology and agronomic components of first and second-cycle strawberry
RESUMO Em busca de maior retorno econômico após o transplantio das mudas, muitos produtores de morango têm feito o cultivo por dois ciclos consecutivos. No entanto, há necessidade de estimar o desenvolvimento fenológico e avaliar o potencial agronômico do morangueiro nesse sistema. O objetivo deste trabalho foi comparar a necessidade térmica, a taxa d

7. Morphogenic, structural, productive and bromatological characteristics of Braquiária in silvopastoral system under nitrogen doses
ABSTRACT. This study aimed to evaluate the effect of different doses of nitrogen fertilization on the morphogenic, structural, productive and chemical composition of Urochloa decumbens (Stapf) R. D. Webster cv. Basilisk in a silvopastoral system with eucalyptus. The experimental treatments consisted of pastures of Basilisk cultivar, fertilized with 0, 100, 2

8. Phyllochron and leaf appearance rate in oat
Abstract Phyllochron and leaf appearance rate are both important parameters in the production efficiency of agricultural crops. The objectives of this study were to determine the phyllochron and leaf appearance rate in 4 oat cultivars (Avena sativa L.) in 3 sowing dates and verify the variability of phyllochron and leaf appearance rate among cultivars and so

9. Effect of water stress on the growth of Arachis pintoi plants under different nitrogen levels
The objective was to evaluate the growth of Arachis pintoi fertilized with nitrogen and water deficiency conditions. The study was developed in a 4 × 4 factorial arrangement with four nitrogen levels (0, 40, 80 and 120 kg N/ha) and four irrigation levels (25, 50, 75 and 100% of field capacity), in a completely randomized experimental design, with four repli

10. Biomass flow in Tifton-85 bermudagrass canopy subjected to different management strategies under rotational grazing with dairy goats
Biomass flow characteristics and forage accumulation were evaluated in Bermudagrass (Tifton 85) pasture managed under intermittent stocking with different management strategies. The management levels utilized were conventional (10 cm residual height and unfertilized), light (20 cm residual height and unfertilized), moderate (20 cm residual height with fertil

12. Biomass flow in massai grass fertilized with nitrogen under intermittent stocking grazing with sheep
This study evaluated the biomass flow of massai grass in regrowth subjected to different nitrogen levels (control - no fertilization; 400; 800; and 1200 N kg ha-1year-1) and under rotational stocking with sheep, in a completely randomized design with repeated measures over time. The leaf elongation rate increased with increasing nitrogen levels (N) and the f
