Item Adubação mineral e orgânica da abóbora híbrida II. Estado nutricional e produção(Antônio Henrique Garcia, 1999-06) Silva, Natan Fontoura; Fontes, Paulo Cezar Rezende; Ferreira, Francisco Affonso; Cardoso, Antônio AméricoIn order to evaluate the response of hybrid squash cv. Tetsukabuto to organic compost and mineral fertilizer (NPK), seven experiments were carried out on a cambic yellow-red Podzol soil under field conditions at Ponte Nova, Minas Gerais State. Each experiment constituted one sampling date, that begun at the 21st day and ended at the 105th day after planting, with 14 days intervals. In these experiments five fertilizing treatments were tested plus a control (no treatment). In the fertilizing treatments, defined by a diagonal section of a complete factorial, rates of 0, 3, 6, 9 and 12 t/ha (dry basis) of organic compound, associated were applied with rates of 0.772, 0.579, 0.386, 0.193 and 0 t/ha of NPK (4-14-8), respectively, with four replications in a randomized blocks design. The NPK and organic compost association increased the plant leaf number, the main branch length and the fruit yield. The maximum yield and maximum economical efficiency, 13.596 and 13.368 t/ha, were obtained with the rates 6.402 t/ha of organic compost and 0.360 t/ha of NPK and with 5.247 t/ha of compost and 0.434 t/ha of NPK, respectively. At the 49th day after sowing, the concentrations of N, P, K, S, Ca and Mg, in the leaf blade dry matter, associated with the maximum economic return, were: 38.8; 5.2; 27.5; 2.5; 21.3 and 3.8 g/kg, respectively. These data, at the 63rd day after sowing, were: 43.8; 4.7; 24.4; 2.5; 18.3 and 5.3 g/kg, respectively. At 105th after sowing, the estimated contents of N, P, K, S, Ca and Mg in the aerial part and expressed in g/plant were 27.8; 4.7; 26.7; 1.8; 10.1 and 4.8, respectively.Item Produção de frutos de abóbora híbrida pela aplicação de 2,4-D nas flores(João Batista Duarte, 2001-06) Pasqualetto, Antônio; Silva, Natan Fontoura da; Ordonez, Gustavo Pazzetti; Barcelos, Rhard WillianFor turn round the imperfect in the squash hybrid pollination process “Tetsukabuto” and to assure the fruits perfect development, it can be adopted the chemical substances use that stimulate parthenocarpy. It objectified therefore evaluate your performance in increasing doses function of 2.4–D (0, 50, 100, 150 and 200 mg/L de 2.4-D) applied in the feminine flowers. The results demonstrated that the dose of 150 mg/L of 2.4-D tended to elevate the fruits number for plant and the middleweight of the fruits for plant, however, significative only was going demonstrated for fruits total weight for plant, with increase in the production in the order of 68.10% when compared the control.
