Maize (Zea mays L.) is the second most important cereal crop of Indonesia after rice. The productivity of corn in Central Java province in 2015 was increased that considered as relatively low. Maize productivitiy needs to be improved to supply the requirement of people through of plant spacing and use the hybrid maize varieties. The aims of study was to determine the effectiveness level of plant spacing, to test the best hybrid maize varieties, and test the combination of two treatments to optimize the yield potential hybrid maize. This study has been conducted from June until October 2017, at Desa Srimartani, Kecamatan Piyungan, Kabupaten Bantul, Daerah Istimewa Yogyakarta. This study was arranged in Split Plot Design consisting of two factors that have been researched, varieties (ABCD, EFGH, NK6172, P27 and DK77) and plant spacing (70 x 20 cm, 75 x 20 cm, and 75 x 25 cm). The results show that treatment of varieties mostly can increase all of variable analysis but there is no interaction on both treatment except plant height, fresh and dry biomass weight. Variable of plant height, tasseling and silking, cob weight with husk, cob weight without husk, kernel seeds weight per plot, 100 seeds weight, yields per hectare show that the highest average is variety of P27. While treatment of plant spacing has no effect because the interval between treatments plant spacing is too close therefore it shows insignificantly different result. The highest dry kernel product on variety treatment P27 (8,82 ton ha-1), followed by DK77 (8,53 ton ha-1), ABCD (8,50 ton ha1), NK6172 (8,34 ton ha-1), and EFGH (7,13 ton ha-1).
玉米(Zea mays L.)是印度尼西亚第二大重要的谷类作物，仅次于水稻。2015年中爪哇省玉米产量有所提高，但被认为相对较低。玉米产量需要通过株距调整和玉米杂交品种的使用来满足人们的需求。研究的目的是确定植株间距的有效性水平，筛选最佳杂交玉米品种，并试验两种处理组合以优化杂交玉米的产量潜力。该研究于2017年6月至10月在日惹的Desa Srimartani、Kecamatan Piyungan、Kabupaten Bantul、Daerah Istimewa进行。本研究采用分畦设计，以ABCD、EFGH、NK6172、P27和DK77为研究因子，株距为70 × 20 cm、75 × 20 cm和75 × 25 cm。结果表明:各品种处理除株高、鲜生物量和干生物量外，对各变量分析均有显著提高作用，但不存在交互作用。株高、抽穗率和出丝率、带壳穗轴重、去壳穗轴重、单田粒重、百粒重、公顷产量等变量均以P27平均最高。而株距处理不产生影响，因为处理间株距太近，结果差异不显著。干粒产量最高的品种处理为P27 (8.82 t hm -1)，其次为DK77 (8.53 t hm -1)、ABCD (8.50 t hm -1)、NK6172 (8.34 t hm -1)和EFGH (7.13 t hm -1)。

One type of vegetable products in Indonesia is cabbage. However, in the application of cultivating cabbage vegetables had experienced some problems, especially the crop caterpillar of Plutella xylostella. Pest control at the level of farmers in some areas, generally they still use chemical pesticides. As a solution for excessive use of chemical pesticides, the use of botanical insecticides is interesting to develop. One of the plant materials that is easily found in the surrounding environment is “beluntas” leaf (Pluchea indica L) containing alkaloids, flavonoids, saponnins, and tannins. The purpose of this study was to determine the effect of leaves extract of (P. indica) on caterpillar mortality of P. xylostella and the phytotoxicity effect on pakcoy. The results of the research showed that the extract wasn't sufficiently able to affect the larvae mortality of P. xylostella, The treatment concentration of 30% however was able to suppress the emergence of the imago. The extract did not show any phytotoxicity symptom the pakcoy .

Arrowroot (Marantha arundinacea) is potential plant to be developed in Indonesia. Arrowroot usually grows wild without special treatment so that makes the productivity is low. The purpose of research was to find the suitable planting age and seeds origin of arrowroot. The research was conducted from October 2016 to November 2017 at Experimental Field of Agriculture Faculty of Universitas Sebelas Maret. The research used RCBD (Randomized Completed Block Design) with two factors.The treatment of planting age consist of 3 levels (1 month, 2 months, 3 months) and seeds origin consist of 2 levels (tuber seeds and seed of nursery), each is repeated 4 times with 3 plants each replication. The results showed that the planting age treatment at 1 month of planting age has the better result compared with other treatments in almost every variables observed i.e plant height, number of tillers, tuber lenght, diameter tuber, and tuber weight per plant. The number of leaves,fresh weight plant, dry weight plant, and number of tubers are not significantly different at 1 month of planting age, although the plant is higher. The highest lenght of tuber is 20,5 cm from 2 months of planting age. Tuber weight of planting age treatment reached 31,8–124,9 gram per plant. Seed of nursery showed better results than tuber seeds although not significanly different. Between planting age and origin of seeds was no interaction.
竹芋(Marantha arundinacea)是印度尼西亚有潜力开发的植物。竹芋通常野生生长，未经特殊处理，导致产量低。研究的目的是为了确定竹芋的适宜种植年龄和种子来源。该研究于2016年10月至2017年11月在西班牙塞贝拉斯市场大学农业学院实验田进行。研究采用RCBD(随机完成块设计)，有两个因素。苗龄处理分为3个层次(1个月、2个月、3个月)，种源处理分为2个层次(块茎种子和苗圃种子)，每个重复4次，每次重复3株。结果表明，植龄1个月处理在株高、分蘖数、块茎长、块茎直径、单株块茎重等各项指标上均优于其他处理。苗龄1个月时叶片数、鲜重株数、干重株数、块茎数差异不显著，但植株较高。种植2个月后块茎最高可达20.5 cm。种植年龄处理的块茎重量达到31.8 ~ 124.9 g /株。苗圃种子效果优于块茎种子，但差异不显著。播种年龄与种子产地之间无交互作用。

Pumpkin is a promising commodity to be developed as food substitute for flour-based flour. Pumpkin cultivation is currently cultivated by farmers on dry land as secondary crop. Pumpkin cultivation constraints as requires a large area and long time. Pumpkin commodities development can be done by hydroponic substrates cultivation that have advantages to accelerate the plant growth, can be cultivated on limited area, and increase the quality of plant yields. The hydroponic substrate cultivation depends on the quality of nutrients as well as the availability of the nutrients. The aim of this research is to study the response of plant flowering to the composition of nutrients (modification of the balance of Nitrogen and Phosphor) and concentration of hydroponic substrate nutrition solution and interaction between treatments. This research used Completely Randomized Design which consists of 2 factors, nutritional composition and concentration of solution with 3 replications and each treatment consist of 6 plants. Observation variables included flower age, flower position, and number of flowers. The results showed that there were interactions between the treatment of nutrient composition and adjustment concentration on the observing variables flower age appear, and flower position. Nutritional composition with the balance of elements of Phosphorus and Nitrogen shows the higher balance of Phosphorus elements followed by lower Nitrogen elements tend to give a lower response to flowering pumpkin on hydroponic substrate. Adjustment lower concentration of application solutions (20 ml concentrated in 1 L solution) or equivalent to EC 3.8-4.0 mS/cm gives a better response to flowering pumpkin on hydroponic substrate.

Each of treatmnent replicated three times. The parameters analyzed were plant height, number of leaves, leaf area, plant dry weight, fruit weight per plant, fruits weight per pieces, fruit length, and fruit diameter. The results showed that honey pumpkin gave the same response to the natural PGRs with various dosages on plant height, number of leaves, plant dry weight, fruit weight, fruit length, and fruit diameter. But, honey pumpkin gave the different response on the leaves area and fruit weight per plant. The largest leaves was found by giving extract of banana bulb of 300 ml (7119.8 cm2) and the mixture extract (onion bulb + bamboo shoots + banana bulb) of 300 ml (6978.5 cm2).

Cauliflower is one of the popular vegetables and has high economic potential. The need for vegetables is high but the productivity is increasingly starting to decline due to narrow land. Hydroponic technology does not require fertile are. Hydroponics of cauliflower expected to increase economic value. Bagasse has characteristics wet and easy to absorb water is very suitable as a media hydroponic substrate. The experimental research was held out from August 2016 until February 2017 in the screen house of the Faculty of Agriculture, Sebelas Maret University, Surakarta The experiments using complete randomized design with 2 treatment factors consisted of various nutrients (2 types) and media (3 types) resulting in 6 treatment combinations, each repeated 3 times. Nutrient types are standard nutrients and modified nutrients (standard K reduction nutrients).The types of media types are bagasse, bagasse + gravel, and bagasse + red brick fractions. Bagasse + fragment red brick showed better yield on volume of root, large of leaf, biomass of plant and age of flower. While the highest of plant on media bagasse + gravel.

The efforts of production enhancement of sweet potato are limited by some constraints including some pest. One of the important pests is sweet potato weevil (Cylas formicarius Fabr.). The use fertilizer and kind of variety are important factors determining the yield of sweet potato. This study aims to examine the effect of manure on three varities of sweet potato and evaluate the yield of varieties test on sweet potato weevil, through choice test and no choice test. The research in field used Randomized Completely Block Design (RAKL) with two treatments. The varieties (Korea, Manohara, Madu) and manure (control, cow manure, chicken manure). Research in laboratory used three varieties and adult of C. formicarius. The result showed that granting of chicken manure on Manohara varieties gave the best response on a length of stem, number of leaves, fresh weight and weight of tubers. Granting of cow manure on Manohara and Madu Varieties give the weight of tuber stricken was less than Korea varieties. Choice test in Manohara varieties show the high population and in no choice test show Korea Varieties had high population of C. formicarius.
