Productive and nutritional evaluation of forage crops at the agricultural experimental station of Satipo

Abstract

The research was carried out in the Tropical Forage Bank of the Satipo Agricultural Experimental Station UNCP, in the wet season (November-March) and drought (May-August), this had a duration of 09 months, between August 2018 to March 2019. The objective was to evaluate the productive and nutritional yield of tropical forage species. The methodology used was an applied study of non-experimental descriptive level; the analysis of the productive yield of green matter was by the square meter method, for the evaluation of the net productive value (dry matter) a sample of 100g was selected and placed in an oven, It was weighed every hour to evaluate the process and culminated when in two consecutive weighings the same weight was obtained. Finally, the nutritional value (crude protein) was evaluated using the Kjendahl method. The results revealed that, in the rainy season Brachiaria Piata with 2.90kg/m2, has the highest green matter yield, followed by Brachiaria decumbens 2.88kg/m2 and in the dry season the forage Panicum maximun with 2.26kg/m2 had the highest yield. 26kg/m2. Regarding dry matter content, the species Brachiaria Piata (68.80m.s.) had a higher content in the rainy season and in the dry season, Pennisetum hybridum (63.18m.s.). In terms of nutritive value, Brachiaria decumbens 16.64% had a higher value in the rainy season and during the dry season Pennisetum violaceum 14.50% had a higher nutritive value. In conclusion, production levels and nutritional value are influenced by exogenous and endogenous factors of the tropics.
