Abstract

Research on the response of sorts and kinds of organic fertilizer mulch on crop yields caisim mustard (Brassica juncea L.) var. Tosakan been conducted from October to December 2014 in the hamlet Paingan, Mangunrejo Village, District Tegalrejo, Magelang. Altitude of 800 m above sea level studies and types of soil with a pH of 6.5 latosol. The method used was factorial with complete randomized block design consisting of two factors. The first factor is the kind of organic fertilizer (P), consisting of no fertilizer (Po), cow manure (P1) and manure goat (P2), the second factor is the kind of mulch (M) consisting of mulch black silver (M1), straw mulch (M2) and bamboo leaf mulch (M3).The results showed that the effect on the kinds of organic fertilizer plant height, number of leaves per plant, leaf weight per plant consumption, heavy consumption of leaves per plot and leaf area per plant, but has no effect on the weight of fresh roots per plant. Kind of care mulch affect plant height, number of leaves and leaf weight per plant consumption, but has no effect on the weight of leaf consumption per plot, leaf area per plant and fresh weight of roots per plant. There is no interaction between the kinds of organic fertilizers and mulch sorts against the weight of leaves per plant consumption.

Abstract

A research on yield of Sweet Corn (Zea mays var. saccharata) at Various of Manure and Concentration of EM4, was conducted in October – December 2014. The location in District Mungkid, Magelang Regency, with altitude of 350 meters, with latosol soil type and soil acidity 6,0. This research used factorial (2 x 4) experiment with randomized complete block design repeated in three times. The factor is kind of manure : goat manure and chicken manure. The second factor is concentration of EM4 : 0, 5, 10 and 15 ml/l. The results show that increasing of chicken manure increase plant height, cob weight without husk leaves, sugar content, weight of 1.000 dry seeds, dry weight of the shoots and dry weight of roots, but not increase number of leaves. Treatment concentration of EM4 not increase plant height, number of leaves, cob weight without husk leaves, sugar content, weight of 1.000 dry seeds, dry weight of the shoots and dry weight of roots. Increasing concentration of EM4 on goat manure and chicken manure same response by the plant, so it does not improve all parameters were observed.

Abstract

The research about the effect of giving organic mulchand NPK (15:15:15) fertilizing time on Baby Buncis (Phaseolus vulgaris, L.) France varieties was carried out on January 26rd until March 28rd, 2017. The location of this research was carried at Windusari Village, Windusari District, Magelang Regency. The altitude of location is 450 meters above sea level and the soil type is latosol with pH of 6,8. The experiment was conducted by using a factorial (3x3) that was arranged in a complete randomized block design, repeated three times. The first factor is mulch kind:no mulch, straw and bamboo leaf. The second factor isNPK (15:15:15) fertilizing time: 5 and 10 ; 10 and 15 ; 15 and 20 days after planting. The result of the research shows that straw mulch givesa lot of number of pods per plant, havier fresth weight of pods per plant and longer height of pod per plant. NPK (15:15:15) fertilizing time which at 15 and 20 days after planting gives longer length of pod per plant. Baby Buncis plant shows the same response on mulch kinds at different NPK (15:15:15) fertilizing time.

Abstract

This study aims to determine the types of pests that attack the various stages of plant development strawberries and measure the extent of damage to strawberry plants caused by pests. These observations were made in Tlekung Experimental Station, Research Institute for Citrus and Subtropical Fruit, Batu municipality, East Java in July until September 2018. The strawberry plants were observed consisting of three varieties, namely Sweet Charlie (SC), Dorit (DR), and Early Bright (EB). Each variety consisted of 20 plants in the vegetative and generative phases with different planting locations were in the screen house and open fields. Observations intensity of pest attacks were divided into three, namely the intensity of leaf-eating pests, pest mites and pests of fruit eaters. The results showed pests that attack strawberry plants consist of the phylum Mollusca and Arthropods. The highest intensity level of pest attacks occur at the location of strawberry cultivation in open fields than the strawberries grown in the screen house that is the pest mites reached 91,25%, which is included in the category very heavy attack on the variety SC. SC varieties were most susceptible varieties against leaf-eating pests and pest mites. Susceptibility to pests highly dependent on the age of the plant, character growth, and morphological characters.

Abstract

Cocoa is a strategic commodity for plantation in Indonesia. However, pest and disease infections are inevitably common constrains for the cocoa cultivators. Cocoa mosaic disease is one of disease which is cause cocoa trees suffering. Pseudomonas fluorescens are obligate aerobic bacteria that are very valuable for agricultural technology. The bacteria also protect plants from pathogens infection by producing secondary metabolites that kill bacteria and other fungi. The bacteria can use as safe and environmentally friendly biological control agents. This study aims to determine P. fluorescens liquid fertilizer formulation and its effectiveness in suppressing mosaic disease in cocoa plants. The research method was carried out by making a liquid formula from P. fluorescens and then applying it to cocoa plants that were attacked by mosaic disease. Bacteria isolates grown in conch broth medium were incubated for 3 days. Then the fertilizer formula was applied to mosaic symptomatic cocoa plants with fertilizer concentrations of 25%, 50% and 75% compared to spraying using chemical insecticides. The results showed that the liquid formula concentration of 75% can suppress the most effective mosaic symptoms and the optimal growth of cocoa plants for 7 treatments..  Keywords: Cocoa, Formulation, mosaic disease, Pseudomonas fluorescens

Abstract

This study aims  to determine the use of bamboo shoots as an alternative phytohormones in spurring shoot growth in dormant seeds. Bamboo shoots contain calcium (Ca), magnesium (Mg), phosphorus (P), potassium (K), sodium (Na), various vitamins and other minerals. Based on several studies, it was shown that the use of bamboo shoots by means of extraction can spur growth in candlenut seeds, sengon seeds, and cayenne seeds.

Abstract

An experiment about of the effect auxin kind on growth of seedling of teak varieties (Tectona grandis, L.) had been done since February 15, 2016 until May 7, 2016 in Field Station on Seed Development Center and Pilot Forestry Yogyakarta at Bunder Village, Playen District, Gunung Kidul Regency, Yogyakarta which the type of soil latosol, pH 6,8 and an altitude is 160 m above sea level. The method of experiment is factorial (4x3) with randomized completely block design and three replications. The first factor is kind of auxin; there are four levels: control, IAA, IBA, NAA. The second factor is kind of varieties, there are three levels: Thailand (Siam), Cepu (Supergama) and Wanagama (Utama) variety. The result of analysis show that the uses of IBA may increases of shoot height; fresh and dry weight of shoot, root length, also fresh and dry weight of root. Cepu variety (Supergama) show the higher shoot and heaviest fresh weight of shoot. There were no efect between kind of auxin and varieties at all parameters.

Abstract

The research is to study the effect of kind of media and the effect of kind of urine to the strawberry yield (Fragaria ananassa). The experiment was done in 10 October 2016 until 29 Desember 2016. Location of experiment is in Sumber, Dukun, Magelang. The altitude is 660 m. The soils is regosol with pH 6,3. The research method used factorial experiment (3x3) arranged in a randomized complete block design with three replications. The first factor is kind of media goat manure, compost, rice husk. The second factor is kind of goat urine, rabbit urine and cow urine. The result of the research show that the use of kind of goat manure media shortened flowering age, icreases number of flower, weight of fruit, fresh weight of stover and leaf width. Compost manure increases weight of fruit and leaf width. Rabbit urine increases number of flower, number of fruit and weight of fruit. The combination of compost media and goat urine accelerate flowering age.
