Afegir etiqueta | Sumari: | The present investigation was carried out in Mr. Hector’s Escobar property, located in the parish Atahualpa of the sector Samanga, county of the Tungurahua to 5 Km of the city of Ambato. The geographical coordinates are: 1º22'02 '' of South latitude and 78º36'22 '' of longitude West. The field investigation lasted five months. They thought about the following objectives to) to Determine the agronomic behavior of the cultivation of onion (Allium cape L.) variety Pearl with fertilizations chemistry, organic and natural amendments with two application dose b) to Determine the yield and production in the different treatments and c) to Compare the costs of production of the treatments. The treatments under study are: T1 Fertilizer 200 kgha-1 + gallinaza 20000 kgha-1 + you amend 5000 kgha-1, T2 Fertilizer 200 kgha-1 + gallinaza 20000 kgha-1 + you amend 7500 kgha-1, T3 Fertilizer 200 kgha-1 + gallinaza 30000 kgha-1 + you amend 5000 kgha-1, T4 Fertilizer 200 kgha-1 + gallinaza 30000 kgha-1 + you amend 7500 kgha-1, T5 Fertilizer 300 kgha-1 + gallinaza 20000 kgha-1 + you amend 5000 kgha-1, T6 Fertilizer 300 kgha-1 + gallinaza 20000 kgha-1 + you amend 7500 kgha-1, T7 Fertilizer 3000 kgha-1 + gallinaza 30000 kgha-1 + you amend 5000 kgha-1, T8 Fertilizer 300 kgha-1 + gallinaza 30000 kgha-1 + you amend 7500 kgha-1 and T9 Witness fertilizer chemical 300 kgha-1. You uses a factorial arrangement (2x2x2+1) prepared at random in the experimental design of complete blocks (DBCA) with 4 repetitions. To establish the differences among the stockings of the treatments the test of multiple ranges it was used from Tukey to 95% of probability and the variation coefficient is expressed in percentage. The variables were analyzed, mortality of the plants to the transplant to the 8, 16 and 24 days after the transplant (ddt), time of crop, weight of the bulbs, diameter of the bulb, yield for hectare, production costs, utility and relationship benefit/cost. The results of low mortality in the investigation are due to the handling of the experiment, mainly to the disinfection of the floor; since the factors in study don't present statistical differences for this variable. The physiologic maturity of the bulbs of onion variety Pearl to the 120 days after transplant is certain as a characteristic of this variety. The biggest weight of bulb 159,48gr, bulb diameter with 7,02cm, onion production 31.610,67Kgha-1 and utility one has with the treatment T1 in which you applies for hectare 200 kg of chemical fertilizer + 20000kg of gallinaza + 5000 kg of amendments. The treatment witness presents the biggest relationship benefit/cost 1:71. |
