Abstract

This study aimed to evaluate changes in agronomic performances of some sweet potato cultivars planted in the rain-fed dry land and paddy fields. Completely randomized block design with three replications on a single factor of 12 sweet potato cultivars was done in two locations. The first location is the rain-fed dry land that formerly planted corn; located in Jatikerto, Kromengan District, and second is an irrigated paddy field that previously planted with rice, located in Wringinsongo, Tumpang District, Malang Regency. All cultivars that planted in both locations were applied to packaged standard cultivation technology for sweet potato. The parameters observed were storage root weight and vines weight (kg/plant), storage root yields and vines yield (t/ha), harvest index (%) and root/shoot ratio to describe the efficiency level of dry matter translocation to storage root. The results showed that there was a change of agronomic performance in sweet potato cultivars that planted between on the dry land and paddy fields, especially for storage root weight, storage root yield (t/ha) and root/shoot ratio. Changes in the sweet potato cultivation in the dry land to paddy fields are shown by an increase in storage root yields ranging from 2-4 times or reach 206 - 417%.

Abstract

Population growth and shrinkage of productive agricultural land led to the availability of rice as a staple food of the population became unbalanced. Efforts to reduce dependence on rice, the food diversification efforts Alternative High carbohydrate should be done so that the robustness, security and sovereignty panganakan remains guaranteed. Plant squash (pumpkin) is one of the plants that have a high carbohydrate content and has many kinds, so this will make it easier in assembly activities yielding varieties. This study aims to collect many different varieties of pumpkin archipelago as starting materials in the assembly of high yielding varieties of activities, and to investigate and identify the character of vegetative and agronomic characters varieties of pumpkin archipelago. Penelitiandilaksanakan in Randuagung village, Lumajang with altitude of 112 meters above sea level above sea level (asl). Materials used in this study a local pumpkin seeds and pumpkin Lumajang local poor. These results indicate that the ratio of male flowers and female flowers on both varieties of local pumpkin shows the number of male flowers are more than the amount of beta-carotene betina.Kadar interest in Lumajang local pumpkin lower than the local pumpkin unfortunate it is seen from the color of pumpkin faded yellow more yellow and less sense to disease manis.Ketahanan both local pumpkin varieties showed criteria tahan.Umur local male flowers of pumpkin unfortunate faster than local pumpkin Lumajang, but the age of the female flower local pumpkin Lumajang faster than local yellow squash malang.Warna local pumpkins are relatively similar; Lumajang brown, while the local varieties of pumpkin unfortunate there is a difference that is brown and green
