Overcoming Competition From Intercropped Forages on Upland Rice With Optimized Nitrogen Input to Food Production in Tropical Region

Frontiers in Sustainable Food Systems, 2020
Intercropping forage grasses with upland rice is an alternative cropping system to improve agroecosystem diversification and could potentially enhance sustainability in tropical regions.

Estimativa da área foliar de Panicum maximum usando dimensões lineares do limbo foliar Leaf area estimate in Panicum maximum weeds, using leaf blade linear dimension

Planta Daninha, 2001
Com o objetivo de obter uma equação que, por meio de parâmetros lineares dimensionais das folhas, permitisse a estimativa da área foliar de Panicum maximum, estudaram-se relações entre a área foliar real (Sf) e os parâmetros dimensionais do limbo foliar,

Treading Resistance and Breeding of Guineagrass Suitable for Rollbale

Japan Agricultural Research Quarterly: JARQ, 2002
The decrease in dry matter production in guineagrass by the use of a mechanical harvesting system was investigated in terms of treading resistance. It was revealed that treading treatment of stubbles led to a serious decrease in dry matter production while shading of stubbles by foliage did not result in an appreciable decrease in dry matter production.

Adaptation of the C4 grass Panicum maximum to defoliation is related to plasticity of N uptake, mobilisation and allocation patterns

Scientia Agricola, 2012
Dry mass production and persistence of Panicum maximum pastures depends on nitrogen supply. Defoliation influences N uptake and allocation patterns yet its effects on plasticity of N dynamics in P. maximum have not been investigated. Stable isotopes of N

Using near infrared reflectance spectroscopy for estimating nutritional quality of Brachiaria humidicola in breeding selections

Agrosystems, Geosciences &Environment, Volume 3, Issue 1, 2020., 2020
Abstract Brachiaria humidicola (BH) (syn. Urochloa humidicola) is an important forage grass in the tropics due to its capacity to grow in nutrient‐deficient soils, tolerate waterlogging, and inhibit soil nitrification. A major objective of BH breeding is to improve its nutritional quality. Therefore, a rapid and low‐cost method is needed to assess main

Nitrogen-Fertilized Systems of Maize Intercropped With Tropical Grasses for Enhanced Yields and Estimated Land Use and Meat Production

Frontiers in Sustainable Food Systems, 2020
Intercropping grain with forage crops bridges the gap between agriculture and sustainability. In tropical regions, forage grasses are increasingly being adopted as winter pasture intercropped and in rotation with maize to maximize food production ...

B chromosomes in diploid guineagrass (Panicum maximum JACQ.).

Japanese Journal of Breeding, 1988
B chromosomes (Bs) were detected in a diploid guineagrass (2n=16) strain derived from seeds collected in Tanzania. The number of Bs was constant at the metaphase I (MI) of pollen mother cells in the same plant, and the size of the B in the bivalents and univalents was approximately the same as that of the normal (A) chromosomes at MI.

Canopy height impact on legume mass and Megathyrsus maximus tiller dynamics in mixed pastures

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2023
The use of grazing management strategies can influence canopy structure and the permanence of legumes. The objective of this work was to evaluate the determination of forage canopy heights as a grazing management strategy regarding herbage mass ...
