Efecto de tres sustratos orgánicos y una solución nutritiva en la producción de plántulas de tomate

Abstract

The objetives of this investigation were to measure the effects of three types of organic eastes combining with four dosage of nutrient solution, for the production of three tomato plants. The organic eastes used were: worm waste and coffe extract (DLPC) , cacao shell compos (CC ), smashed sugar steam (BCA) it’s , mixes sheep manure with soil (EB+S), and as a witness peat-moss (PPTA) : a these aplication the dosage of nutrient solution folowing: D2 = 2.0 cc of greater concentrate solution (SLN >) plus 1.0 cc of solution less concentrate (SLN < ); D3 = 4.0 cc of SLN > plus 2.0 cc of SLN < ; D4 = 6.0 cc of SLN > plus 3.0 cc of SLN < and the witness D1, wich nutrient solution was not applied to. The Experimental Design was a factorial in randomized design 9x4. Were registered on the plants: Percentage of growth, height of the plants, the weight while fresh, and the tolerance of the plants to the stress caused by the trasplant. The compost CC+S (S5) and DLPC + S (S3), presented a major percentage of growth with a 97.7 and 97.2 respectively. The eastes (s5) the best means of heigh at 15 dds with a means of 5.59 cm to the 22 dds. the mean of heigh was greater for s3 with 8.76 cm. When takin the heigh fresh of 5,10 and 22 ddt the greater date were obtained in S5 and S3. The adaptation of the plants when trasplanted was evaluated throughout the acumulation of dry matter obtaining the best results in S3 with 1.198 g and 11.3 g of 10 and 22 ddt. The best dosage factor was D4 in which the best results were obtained from the evaluated measurements in this exercise.
