Comportamento fenológico da alfafa (Medicago sativa L.) CV. Crioula no sertão paraibano.

Abstract

Alfalfa is one of the most important forages, the greatest variety of farms, protein quality, palatability, digestibility, nitrogen fixation capacity in the soil and low seasonality of forage production. Therefore, the objective of this work was the performance of the crop phenomenon in terms of productivity and its bromatological characteristics in distinct and cutting times. The experiment was carried out at the Campina Grande Federal University, Center for Agro-Food Science and Technology (UFCG / CCTA), at the Pombal campus, at the Experimental Farm in São Domingos-PB. The treatments were divided into forage and seed production at different cutting times. For forage production, plant spacing of 0.25 m was used in a 6 m line, totaling 16 rows (36 m2) and for the production of wood seed-plant spacing of 0.50 m in a row of 6 m totaling 16 lines (36 m2) and four cutting times after standardization cut (30, 60, 90 and 120 days). After the growth and productivity data, the plants were submitted to analysis and subsequent analysis. (CZ), crude protein (CP), dry matter (DM) and dry matter (DM), as well as for the chemical composition, neutral detergent fiber (NDF), acid detergent fiber (FDA) and as corrections of neutral detergent fiber (NDF) and acid detergent fiber (FDA). For the data arrangement, see mean and standard deviations. It can be observed that the factors that contribute most to the productivity and how the times of cuts are found in the 60 and 90 days after the cut of standardization.In conclusion, alfalfa cv. 'Crioula' has high potential for exploration in the Sertão Paraibano regions, besides being a promise for use in animal feed.
