The research was carried out in the experimental fields of the university Nacional De San Martin sect Ahuashiyacu Band Shilcayo Province of San Martin, located at South latitude 6 ° 2T, altitude of 360 m and at a west longitude 76 ° 23 ', has an area of ​​tropical dry forest (bs..T) presents: texture: sandy loam, pH: 4.85, matera organic 3.57 ° .4. block design completely random (OSCA) with 5 treatments and 4 replications. The treatments were 2. 4, 6 TM H. UHA and NPK 160-90-90 and absolute control. ~ Rum treatments that greater plant height and Anura harvest cobs are the T3 (6 TMIHa vermicompost) and 227 .93 cm and 101.00 cm. And the lower results were the TS (absolute control) with 217.95 and 85.78 cm. In grain yield which was obtained higher yield T4 (160-90-90) 3 614. 46 Kg / Ha and treatment that underperformed was the T5 (Witness Absolute) 2 671.81 Kg / Ha. Upon respective e...
