Abstract

A field experiment was conducted at the Research Station of Brawijaya University from April to August 2009.  An augmented, randomized complete block design with seven blocks was utilized with seven parental clones as standard treatments and seven half-sib families as augmented treatments. Each block consisted of seven parental clones plus one randomly assigned family of half-sibs. In addition, the first block contained 29 accessions, the 2nd block had 120, the 3rd block had 194, the 4th block had 45, the 5th block had 28, the 6th block had 186, and the 7th block had 108. Ten cuttings of each parental clone was planted in each block, along with a single plant of each accession at a spacing of 75 cm in the row and 100 cm between the rows. There were five improved clones identified with high protein content and high yield. Broad-sense heritability and genetic advance of storage root weight, storage root number, percentage dry matter and protein content were high, whereas vegetative biomass and harvest index were low. The results showed that storage root weight, storage root number, percentage dry matter and protein content could be used as the basis for a crop improvement program in sweet potato.   Keywords: broad sense heritability, expected genetic advance, improved clones, high yied, protein content, sweet potato

Abstract

This study aimed to classify the types of sweet potato based on the ratio of total dry matter of roots to vine (R/V) in order to make the option available in integrating the crop-livestock systems. Seventeen sweet potato cultivars were planted in Randomized Complete Block Design with three replications applied at two locations, Malang and Blitar. Each cultivar planted in plot measures 2.5 m x 5 m in Malang and 3.0 m x 5 m in Blitar, and each consists of four rows with a spacing of 25 cm in rows. All cultivars gave a dose of 250 kg NPK fertilizer (15-15-15)/ha twice, one-third of dose given at planting and the remainder in a month after planting. Plants were harvested at four months after planting. Fresh weight and dry weight of storage root, fresh weight and dry weight of vines, harvest index, and the ratio R/V are determined.  There was different performance of 17 cultivars planted at two locations. Cultivars planted in Malang were classified into four types, namely forage, which consists of three cultivars among 17 cultivars, low dual-purpose (3 cultivars), high dual-purpose (7 cultivars), and low root production (4 cultivars); while cultivars planted in Blitar turned into the forage type. Keywords: dual-purpose, root/vine ratio, sweet potato

Abstract

Hidden Hunger is a major health problem for the world populations, especially in developing countries. Sweet potato is one of the main staple crops to be enriched with micro nutrient content through biofortification program, to overcome the Hidden Hunger. The study aim was evaluated the offspring performance of the controlled crosses between the parent for the enrichment of micro nutrient content with other high yielding clones. A number of hybrid genotypes (297) scattered in 8 families of half sibs were evaluated by weight of storage root and vines, estimated of storage root and vines yields per hectare, and its micronutrient content (Fe and Zn). Augmented Randomized Block Design with 8 replicate blocks was applied for this trial. In each block is also planted parent clones as control cultivars. The results showed that cultivar test performance on all observed parameters was different to control cultivars, as well as among the cultivars test were also statistically different. This allows obtaining the selection of genotype based on storage root weight/plant and its micronutrient content. Among the 297 genotypes evaluated available of 140 genotypes had storage root yields ≥ 0.5 kg/plant and 6 of them had storage root weight of ≥ 1.5 kg/plant. Based on storage root weight and micro nutrient content selected 6 genotypes with the storage root weight range between 0.598 - 1.631 kg/plant and Fe and Zn content respectively ranged from 95 to 618 mg Fe/kg and 10-12 mg Zn/kg based on dry weight basis.

Indawan et al, 2019. Increasing Sweet Potato Yield on Biochar Amendment Application on Sub-Optimal Dry Land. JLSO 8(1):47-56. Biochar is a soil amendment that can improve soil fertility, increase crop yield and can reduce contamination. This study aim to evaluate the sweet potato response to biochar application from tobacco industry waste. The combination of cultivar and dose of biochar implemented using a Split Plot Experiment Design with three replications. The cultivars placed 0n main plots and biochar doses on sub-plots. The thirteen cultivars covering 7 varieties (Kuningan Putih, Beta 1, Beta 2, Kuningan Merah, Sari, Boko, and Jago) plus six accession from Unitri and Brawijaya University collections (BIS OP-61-OP-22 , 73-6 / 2, 73 OP-8, BIS OP-61, 73 OP-5, and BIS OP-61-♀-29). The biochar dose used was B0 (0 t / ha) and B1 (5 t / ha). The experimental unit is measuring 5 m x 0.6 m, consisting of single row and planted with a spacing of 25 cm in row or 20 cuttings/row). The storage root numbers, storage root weight, % dry matter, Harvest Index (HI) and yields estimation are ditermined. The results showed that sweet potato cultivars gave a significant response to biochar application on fresh storage root weight, dry storage root weight, biomass dry weight, HI and storage root yields, but no interaction between cultivars and biochar doses. Storage root yield range of 8 - 21 t / ha without biochar and 10 - 23 t / ha with biochar 5 t / ha, except for Beta 1 and Boko. The use of biochar of 5 t / ha can increase storage root yields ranging from 8 - 45%.

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%.
