Abstract

Sweet potato (Ipomea batatas L.) is the staple foods for part of Indonesian frequently found at traditional markets with relatively cheap prices. It has potency for substituting rice. This plant adapts well even in less fertile soil conditions, and is resistant to pests and diseases. This study aims to determine the response of sweet potato to the treatment of tillage and the use of shoots as planting material. This research was carried out in the experimental station of IP2TP Muneng Probolinggo, using a divided plot design (RPB) with tillage consisting of 3 levels, namely no-tillage (T0), minimal tillage (T1), and maximum tillage (T2) and shoot segment subplots. The number of shoot segments consists of 3 levels, namely 2 shoot segments (R1), 4 shoot segments (R2), and 6 segments (R3). Results show that 1) maximum tillage treatment (T2) significantly affected plant length, tuber weight, and tuber length, 2) treatment of 4 shoot buds (R2) significantly affected leaf area, wet stover weight, dry stover weight, tuber length and tuber weight, 3) the combination of maximum soil treatment and 4 segments (T2R2) had a very significant effect on tuber weight.Key words: Tillage, Stem Segment, Sweet Potato

Abstract

This study aims to: 1) Knowing the influence of planting distance on the growth and yield of potato crops (Solanum tuberosum L.). 2) Know the effect of the size of seed bulbs on the growth and yield of potato plants (Solanum tuberosum L.). 3) Know the interaction between planting distance and the size of seed bulbs to the growth and yield of potato crops (Solanum tuberosum L.). Hypothesis: 1) Planting distance has a real influence on the growth and yield of potato crops (Solanum tuberosum L.). 2) The size of seed bulbs has a real influence on the growth and yield of potato crops (Solanum tuberosum L.). 3) There is an interaction between the influence of planting distance and the size of seed bulbs on the growth and yield of potato crops (Solanum tuberosum L.).This study uses a Factorial RandomIzed Group Design (RAK) with 2 factors, namely planting distance (J) as much as 4 levels of treatment and the size of seed bulbs (U) as many as 3 levels of treatment with 3 repeats. If the results of the F test show a noticeable effect then the analysis continues Duncan's Multiple Distance Test (DMRT) at a distance of 5%. Conclusion:1) The treatment of planting distance does not affect all observations on potato plants. 2) The treatment of seed bulb size + 30 gr (U3) has the best results, namely on the height parameters of the plant, the number of main stems, the number of branches, the number of bulbs per plant, the number of bulbs per plot, the weight of bulbs per plot, wet brangkasan per plant, wet brangkasan per plot, dry brangkasan per plant, dry brangkasan per plot. 3) The interaction between the treatment of planting distance and the treatment of seed bulb size does not affect all observations on potato plants.Keywords: printed normally, written alphabetically

Abstract

Oyster mushroom is a type of wood fungus that originally grew naturally on tree trunks that had undergone weathering in forest areas. To increase the production of white oyster mushrooms, have to added nutrients from outside in the form of mood boosters as a supporting ingredient for growing media. This study used a Factorial Randomized Block Design (RBD) with two factors. The first factor is various mood booster: rice washing water, coconut water, and sugar water. The second factor is mood booster dose: 0 ml / baglog, 50 ml / baglog, 100 ml / baglog and 150 ml / baglog. Based on the results, it can be concluded as follows: (1) The treatment of various mood booster rice water has effective in providing the best results on the parameters of the number of hoods and fruit weight, (2) Mood booster dose treatment of 100ml/baglog gave the best effects on the parameters of mycelium fulfillment time, pinhead emergence time, fruit weight, and the number of white oyster mushroom hoods, (3) there was an interaction between the rice water mood booster and the 100 ml/baglog mood booster dose against all parameters.
