The main objectives were: to program a software to calculate the costs of seasonalcrop production per hectare; to create a database of inputs, written and verbalagriculture technical information for the central coastal areas, and to validate thesoftware surveyed in a user satisfaction tested to students and academic staff involvedinto agriculture. It allow users to determine the sowing rate per hectare, number offertilizer bags according to NPK formulas, the current input costs, investment costsand profitability in one cropping hectare. The software considered the income, userpassword, initial presentation, general information to register a crop, record of specificdata defined by agriculture tasks, review, correction or adding data from direct andindirect costs, economic analysis, rate of return, final report in local currency (soles)or dollars, and printing the sheet production costs pe...

Los desechos de alimentos dispuestos inadecuadamente generan contaminación del suelo, aire y agua, focos infecciosos de vectores, así como emisiones de CO2. El objetivo de esta investigación fue utilizar residuos de corona de piña como agente estructurante para evaluar la influencia de los espacios de aire libre inicial buscando favorecer la actividad microbiana y alcanzar un menor tiempo de estabilización del proceso de compostaje. La metodología consistió en evaluar un diseño de bloques completamente al azar de pilas de compostaje de 200 kg de residuos de papa, camote y zanahoria en una relación 1:1:1 en peso (TA), mezcladas con coronas de piña al 10% (TB) y 30% (TC) en peso. Se monitoreó los espacios de aire libre, la relación C/N final, la respiración microbiana, la temperatura, el pH, la conductividad eléctrica y la humedad, durante 105 días. Los resultados evidenciar...
