“…The contribution of the livestock sector to total Indian agricultural output is nearly 25.6%. Urbanization has brought a marked shift in the lifestyle of people towards consumption of milk products, meat and eggs, resulting increased demands for livestock products (Ghosh, Palsaniya, Rai, & Kumar, ). Rapidly developing periurban livestock farming, emerging forage markets, a vibrant cooperative dairy sector and increased availability of livestock‐based products in super markets are indicators of fast economic changes in the livestock sector (Ghosh, Palsaniya, & Srinivasan, ).…”

Guinea grass (Megathyrsus maximus) is an important source of forage in India but it remains dormant during the winter season. The space between rows of grass can be utilized by incorporating forage legumes. This 3‐year study evaluated two genotypes of guinea grass in monocropping and intercropping with cowpea and Egyptian clover under different N management options. Guinea grass genotype BG‐2 produced higher dry‐matter yields than BG‐1, both in monocropping and in intercropping. However, dry‐matter yield of forage legumes was higher under BG‐1. The yield advantage in terms of land equivalent ratio was higher in BG‐1 (1.69) than BG‐2 (1.60). BG‐1 was more dominant than BG‐2 in intercropping. Soil properties such as dehydrogenase activity, microbial biomass carbon and available N were improved under grass–legume intercropping compared with grass alone. Higher crude protein and N uptake were also observed in BG‐2. Net returns of grass–legumes intercropping were 30%–40% higher compared with monocropping of guinea grass. Among N management options, higher growth, crude protein content and forage yield were achieved with application of 40 kg N/ha after each cut of guinea grass in double split. Therefore, guinea grass + cowpea–Egyptian clover intercropping with 40 kg N/ha after each grass cut in double split can be suggested for higher forage productivity, profitability and soil properties.

“…Even with high response to N-fertilizer rate by tropical forage, resulting in increasing crude protein (CP), and other bromatological features [10], the risk of higher downward residual NO 3 -N movement in soil and high concentration of NO 3 -N in biomass due to N-fertilizer above plant requirement must be considered to avoid environment contamination and animal health problems [11,12].…”

“…However, this content of CP does not reflect just the real amount of crude protein because it is related to all N forms in tissue, even the NO 3 -N accounts to result in this amount of CP [10].…”

New Perspectives in Forage Crops

There is a concern about the growing population and limitation in natural resources which are taking the population to direct its agricultural systems into a more productive and efficient activity, looking to avoid a negative impact on the surrounding environment. The industry energy expended to produce nitrogen (N)-fertilizer is considered an indirect consumption of energy in agriculture, which is higher with an increasing forage yield. Nitrogen is the key nutrient associated with high-yielding production in forage grass and grain crops. The aim of this chapter is to introduce the best management practices (BMPs) for N-fertilizer application in forage grasses to improve N-use efficiency, since the most economical way to feed livestock is forage plants where its potential biomass production is not well explored. The BMPs basically follow three management practices: (1) soil nutrient availability and forage requirement, (2) fertilizer application, and (3) decrease in nutrient losses from soil. In order to take a decision on applying N-fertilizer to accomplish forage grasses production with social, economic, and environmental benefits, the N-fertilizer use in forage grasses is going to follow the "Right rate, Right source, Right place, and Right time (4R) nutrient stewardship." The application of the 4R's nutrients stewardship is directly associated with economic, social, and environmental impact. The capacity of the 4R's implementation worldwide turns into a best guide to improve the striving of better N-use efficiency in forage grass. The 4R's are interrelated; thus, the recommendation of N-fertilizer rates cannot be prescribed without the combination of the 4R's where a whole system to be followed should be considered to decide about N-fertilizer in pasture. Consequently, any decision in one of the 4R's is going to affect the expected N-fertilizer results and dry matter production.

RESUMO:Com a adoção crescente da irrigação de pastagens no Brasil, são necessários estudos que caracterizem as respostas produtivas com condições ótimas de crescimento em diferentes períodos do ano e quando em consórcio com outras forrageiras. Este trabalho teve por objetivo a caracterização produtiva e biométrica de U. brizantha cv. Marandu em dois sistemas de cultivo (solteiro e consorciado) irrigados em diferentes épocas do ano. Realizado na ESALQ/USP, sob delineamento inteiramente casualizado, utilizando aspersores setoriais espaçados 12x12m para irrigação. Determinaram-se os seguintes parâmetros produtivos: produtividade: total de forragem (PTF), de folhas (PF), de colmos (PC), de material morto (PMM); porcentagens de massa: de folhas (% MSF), colmos (% MSC) e material morto (% MSMM); razão folha-colmo (RFC). A análise estatística foi feita por meio de comparações múltiplas e teste de comparação de médias, com o auxílio do software ASSISTAT 7.7. Os resultados demonstraram que a produção máxima do capim Marandu foi de 2500 kg MS ha -1 (verão) e 1300 kg MS ha -1 (inverno). Quando em sobressemedura, não houve diferença significativa entre os ciclos na PTF.
