Some composts can produce phytotoxins that inhibit the development of plants and the absorption of nutrients by an excess of indoleacetic acid if the compost is not mature. In the present work, the objective is to evaluate the quality of the compost by means of direct tests of phytotoxicity and agronomic quality with different composts. To determine the quality as organic compost and vermicompost fertilizer were considered physical, chemical and biological variables according to existing manuals. The results obtained for these variables were: In the physical, chemical and biological variables, all the parameters are fulfilled according to the norm. Seed germination of vegetables increased with respect to the control in 14.93%, possibly due to the presence of some root development promoter found in the compost. With regard to survival the witness was inferior by 3.08% Although the amount of nutrients found in composts are not so high, they comply with the minimum requirements of the regulations to be used as a substrate in horticultural applications. Conclusion, the results of this study indicate that the compost elaborated with any type of residue can be used as a substrate in seedbeds of chili, onion or other vegetables to induce germination and accelerate the development of plants.
Study was performed in Chacala, Cabo Corrientes, where the species in study are widely distribuited in a natural form. Bromatologic analisis of fruit of B. alicastrum and E. Cyclocarpum were performed as an alternative to improve animal production, increasing protein consumption, energy and minerals on the livestock diet. Bromatologic analysis was made for crude protein (CP), etereum extract (EE) and nitrogen free extract (NFE) with Wendee method (AOAC, 1990); neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose, hemicellulose and lignin (Van Soest and Wine, 1967) with ANKOM equipment. Calcium and phosphorus for colorimetry, potasium with flamometer technique (Van Soest, 1979); magnesium, sulphur and copper with TMECC 04.06 / 4.13 method. Nutritional quality was analized on dry matter, ashes, fat and crude fiber. Significative difference was obtained between species on protein (22.90 vs 10.88), fiber (7.24 vs 13.18) and NFE, were the higgest value was for B. alicastrum (67.02%) compared with E. cyclocarpum (60.45%). Inclussion of fruit flour from E. cyclocarpum and B. alicastrum on ovine alimentary rations improvement consumption. Weight increase and alimentary convertion were better with the 10% inclussion. Economic value of alimentary rations with inclussion of fruit flour of E. cyclocarpum and B. alicastrum was lower than witness diet on stabuled ovine, permiting maintain development with significative decrease of production costs.
Fruit and seed productive capacity and physiological seed quality of 2 varieties of husk tomato were estimated: Jojutla and CHF1. The study was conducted in hydroponics under greenhouse, in the CUCBA-UDG, Zapopan, Jalisco. Red volcanic rock (/Tezontle) of 0.5 to 2 cm in diameter was used in 19 L polyethylene bags and Steiner's universal nutrient solution of 0.3 to 0.7 atm, depending on the stage of the plant. The production of fruit and seed and the physiological quality of the seed were estimated. The varieties Jojutla and CHF1 showed a similar behavior in the production of fruit and seed, with lower fruit yields than expected (30 ton / ha in the field) because only 3 harvests were made, looking to produce husk tomato in winter when it reaches attractive prices. The weight of the fruit was greater as cuts were made while the seed production improved by cutting, associated with a greater number of fruits, while the weight of the fruit was not related to the seed yield. The physiological quality of the seed was affected by cutting the fruit to commercial maturity even when it was left to mature in the shade.
