ABSTRACT In this work, the effect of manure and NPK fertilization on the yield of Hordeum vulgare L. var. Zapata and was installed on January 4, 2018 in the Alto Paraíso hamlet, located in the province of Santiago de Chuco, using a randomized complete block design with four repetitions and nine treatments in 3x3 factorial arrangement. The treatments were three sources of sheep manure: 0 t. ha-1, 2 t. ha-1, 4 t. ha-1 for three levels of NPK fertilization: 0-0-0; 40-40-40 and 80-80-80 kg. ha-1 of N, P2O5 and K2O, respectively. The number of plants per square meter, tillers per plant, spikes per plant, spikes per square meter, grains per spike, spike length and plant height were evaluated. It was found that, with the incorporation of 4 t. ha-1 of sheep manure, a higher yield of barley (3.42 t. ha-1 grain) is obtained in relation to the control without manure (2.58 t. ha-1 of grain). With the incorporation of 4 t. ha-1 of sheep manure, a higher plant height (95.01 cm) and a greater number of spikes per square meter (707 spikes) are obtained in relation to the treatment without manure (84.68 cm and 603 spikes, respectively). With the 80-80-80 dose of NPK, a higher plant height (96.69 cm), a greater number of tillers per plant (2.19 tillers) and spikes per plant (2.19 ears) are obtained in relation to the control treatment (78.36 cm, 1.89 tillers and 1.88 spikes, respectively). Only when manure is not incorporated is response to fertilization at the 80-80-80 dose of NPK in spike length (63.5 mm) and in number of grains per spike (46.49 grains) in relation to treatment 0-0- 0 NPK (50.0 mm and 37.23 grains, respectively). The yield of barley var. Zapata in Alto Paraíso, Santiago de Chuco is affected by the incorporation of manure and not by NPK fertilization.
