Abstract

For cultivation of melon (Cucumis melo L.), farmers only keep one fruit per plant to maintain quality fruit. To improve productivity, one possible effort is by spraying gibberellins at melon in combination with increasing amount of fruit maintained for each plant. The aim of this study was to know the effect of gibbereline in improving sink capacities of melon when fruit amount is increased. Gibberelins was sprayed at concentration of 0, 30, 60, and 90 mg/l to melon crop with different fruit amount per plant (one, two and three fruit). The study indicated that for melon plant with more than one fruit per plant, gibberellins application was not able to maintain the fruit quality, because the fruit weights were still decreasing. Thus, gibberellins application was not able to improve the sink capacities if fruit amount per plant is increased. While for plant with only one fruit, spraying 60 and 90 mg/l gibberellins can improve the fruit weight, so gibberellins improves the sink capacities if only one fruit is maintained for each plant.

Abstract

The study on the innuence of altitude and season toward aphid population fluctuation inpotato plant. This research was carried out in Rimbo Data, Aia Butunibuak and Sukaraniiareas. Aphid identification was done in Laboratory of Agronomy Study Program, Faculty ofAgriculture, Andalas University, Padang, and in the Research Hall of Fruit Plant, Solok. Theaphid population fluctuation was observed by capturing the aphid flying by installing threetraps of Moerickc tray put in the potato plantation in each area. Treatment of this researchwas in the difference of position altitude of the capture area, viz, Rimbo Data (1,700 mDPL), Aia Batunibuak (1.350 m DPL), and Sukaranii (1.000 in DPL). The research resultshowed that the aphid population in the potato plantation was lower in the area of RimboData (1.700 m DPL) compared with the area of Aia Baturnbuak (1,350 m DPL) and Sukarami(1.000 m DPL). The period witliout aphid was only found in the area of Rimbo Data atOctober, and January, The type of dominant aphid in Rimbo Data was Macrosiphumeiiphorbiae, in Aia Baturnbuak and Sukaranii were Aphis fabae.
