Yield Response of Ten Varieties of Sweet Potato (Ipomoea Batatas L.) Cultivated on Dryland in Rainy Season
Sweet potato is a tuber commodity and one of alternative crops in Indonesia. The demand of sweet potato in Indonesia continues to increase. However, the supply of sweet potatoes for consumption estimated is 2020 in Indonesia will be deficit. Low production of sweet potato is basically due to the decrease of land area as cultivation production and also sweet potatoes have a low yield when planted in rainy season. Based on the high utilization of sweet potato make demand for this commodities continues to increase.Therefore, several strategies to increase crop yields of sweet potato needs to be done. This study aimed to elucidate various sweet potato varieties that can cultivated on dry land in the rainy season. This study was conducted from November 2016 until March 2017 using a randomized block design with treatments of ten varieties of sweet potato consisting of (V1) Papua Solossa variety, (V2) Jago variety, (V3) Kidal variety, (V4) Antin-1variety, (V5) Sari variety, (V6) Sawentar variety, (V7) Beta-2variety, (V8) Antin-2variety, (V9) Antin-3 variety, (V10) Beta-1variety. The results showed different responses of each variety.The vegetative growth was high as shown by the LAI value of 7.23 at 90 days after planting. In conclusion, the sweet potato leaves had to be prune to boost the agronomic yield. Yields of ten varieties of sweet potato crops ranged from 8.86 to 44.76 t/ha. Some varieties such as Sari, Papua Salosa and Beta-2 varieties showed high yield although they were planted in moorland conditions in the rainy season
The effect of leaf bud trimming and fruit position arrangement on the quality of golden melon (Cucumis melo L.)
Melon are one of the most popular fruit commodities, but, despite the demand,
its production in Indonesia has declined. One measure that can be used to
optimize the quality of melon fruit is to trim off the leaf buds and arrange the
position of fruiting on the stem, and this study, using the golden melon cultivar
‘Apollo,’ aimed to identify the effects of leaf bud trimming and fruit position
arrangement in improving the quantity and quality of the fruit harvest. The
experiment was conducted from March to May 2018 in the greenhouse of
Food Crop and Horticulture Agribusiness Development (UPT Pengembangan
Agribisnis Tanaman Pangan dan Hortikultura), in Lebo, Sidoarjo, Indonesia.
It was based on a split-plot design, with leaf bud trimming as the main factor,
consisting of two groups (trimming or not trimming), and fruit positions as the
secondary factor, consisting of four stages, all repeated at four different time
intervals. A correlation was found between leaf bud trimming and fruit position
arrangement toward the number of leaves. However, the treatments did not affect
the growth and yield of the plants, but did have a significant effect on fruit weight,
sweetness, and volume. It was concluded that trimming off the leaf buds and
arranging the fruiting position on golden melon plants can increase the quality of
fruits, with the treatment involving trimming combined with arranging fruiting
on the twelfth–thirteenth segment showing the best results
