“…Plant height, flowering, DMB and crude protein of the collection were higher during the rainy season, contrasting with stress, growth, and production limitations during the dry season (Hare et al, 2015), which indicates that the water supply favors agronomic characteristics and protein content (Larsen et al, 2021). Weather characteristics have an effect on agronomic and nutritional parameters for M. maximus (Machado, 2013;Lemos et al, 2017;Maranhão et al, 2021;Marcillo et al, 2021).…”

The diversity and use of tropical forages for cattle feeding are the protagonists in livestock systems. The production and nutritional quality of forages represent a strategy of continuous research in animal feeding to help mitigate the environmental impact generated by tropical livestock. The objective of this study was to classify the nutritional behavior in contrasting seasons and the relationship with agronomic traits of a collection of 129 CIAT (Centro Internacional de Agricultura Tropical) accessions of Megathyrsus Maximus established in the Colombian dry tropics. By means of the near-infrared reflectance spectroscopy (NIRS) technique, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and in vitro dry matter digestibility (IVDMD) were determined under rainy and dry seasons as fixed effects. We measured plant height, dry matter biomass (DMB) and flowering in field. Aspects such as plant height and DMB did not show correlation with nutritional aspects, whereas flowering was correlated with the content of structural carbohydrates. Despite genotype and precipitation affecting nutritional value, there is relative nutritional steadiness in NDF, ADF, and IVDMD between seasons for some accessions. According to the cluster analysis carried out for each season, it was evidenced that from the total collection, 51.2% of the accessions during the dry season and 19.4% of the accessions during the rainy season were classified with a better nutritional profile, thus, showing a higher number of materials with better nutritional behavior in the dry season. Both the genotypic characteristics of M. maximus and environmental conditions during contrasting seasons are factors that might influence the variability of the nutritional content, productive parameters, and flowering. Additionally, fodder material classification under Hotelling's T-squared test and Nutritional Classification Index suggests accessions that might be promising for resilient nutritional quality and adequate DMB, which proves that M. maximus could become an alternative for animal feeding and sustainable livestock production during critical dry periods in tropical agroecosystems.

“…Considerada espécie exigente em água, a utilização dessa gramínea em sistemas irrigados e com um manejo adequado proporciona altas produtividades de forragem de qualidade. Nesse sentido, o uso da irrigação é uma alternativa que deve ser considerada para manter modelos de produção baseados em pastagens de capim Tanzânia ao longo do ano (LEMOS et al, 2017).…”

Com o objetivo de avaliar o desempenho desta gramínea sob estresse salino, estabeleceu-se um delineamento experimental inteiramente aleatorizado, analisado em esquema fatorial (5x2), com quatro repetições, totalizando 40 unidades experimentais. Os tratamentos consistiram na aplicação de águas com cincos níveis de salinidade (0,5; 1,5; 2,5; 3,5 e 4,5 dS m-1) às plantas via aspersão e gotejamento. Avaliaram-se os componentes: altura (ALT), fitomassa fresca (FMF) e fitomassa seca (FMS) da parte aérea das plantas, as quais foram obtidas em 4 sucessivos cortes. Concluiu-se que a água de irrigação de elevada salinidade reduz a FMF e a FMS da gramínea, porém, é possível se obter resultados expressivos de produção com uma CEa máxima de 2,8 dS m-1, com reduções máximas de 20% na produção fitomassa seca. Ao se utilizar água salobra, as plantas irrigadas via gotejamento apresentaram resultados de produção mais expressivos em relação às plantas irrigadas via aspersão.

PERFORMANCE OF TANZANIA GRASS IRRIGATED WITH SALINE WATER APPLIED VIA SPRAY AND DRIPPING 2 ABSTRACT Tanzania grass (Panicum maximum) is a forage that has stood out in the last years for feeding animals worldwide. Therefore, the evaluation of its growth and production under saline stress is an important factor to enhance the cultivation of this fodder in semi-arid regions. To evaluate the performance of this grass under salt stress, a completely randomized experimental design was established in a factorial scheme (5x2) with four replications, totaling 40 experimental units. Treatments consisted of application of water with five salinity levels (0.5, 1.5, 2.5, 3.5 and 4.5 dS m-1) to the plants via sprinkling and dripping. The components: height (ALT), fresh phytomass (FMF) and dry matter (FMS) of the aerial parts of the plants were evaluated, which were obtained in four successive cuts. High salinity irrigation water reduces FMF and grass FMS, but it is possible to obtain significant results of production with a maximum ECa of 2.8 dS m-1, and maximum reductions of 20% in dry biomass production. When brackish water is used, plants irrigated via drip irrigation presented more significant production results against plants irrigated by spraying.
