Abstract

Rice is a staple food for most of the population in Indonesia. This study aims to determine the effect of neem leaf plant pesticides on rice lice pests and the optimal optimal concentration of neem leaf pesticides on the development of rice lice pests. This study used a Completely Randomized Design (CRD) with 6 treatments that were repeated 4 times. The design of the study was compiled namely without giving neem leaves (D0 / control), giving neem leaves concentration of 1 gram (D1), giving neem leaves concentration of 2 grams (D2), giving neem leaves concentration of 3 grams (D3), giving neem leaves concentration of 4 gram (D4) and administration of neem leaf concentration of 5 grams (D5). Observations were made on the number of Sitophilus oryzae L. imago mortality and the number of Sitophilus oryzae L. live imago. The results showed that the administration of neem leaf vegetable pesticides on the mortality of rice lice pests was very significant (P <0.01). Concentration of plant leaf pesticides that can inhibit the development of rice flea pests is 5 grams of neem leaf insecticide with 60.00% mortality of Sithophilus oryzae L. after 168 hours application of dried neem leaf insecticide (%).

Abstract

Food security is one of the problems of national food which is very important to avoid food crisis. Plant pests is one of the obstacles to increase agricultural production, greatly affect the rice (Oryza sativa L.) In the agricultural production is inseparable from the name of the production factors one of which is the use of pesticides but its use is extremely unwise evidenced by the number of victims, as a result of chemical residues. Green leafhopper (Nephotettix sp.) is a member of Family Cicadellidae, Order living in the rice plant. An important role is as vector Tungro virus. Pesticide from neem plant is environmentally friendly pesticides that can be used in organic farming. Insects that feed on the leaves, the leaves of plants or directly affected by the extra spray neem growth will be impaired metabolism, interfere with the process of insect metamorphosis so metamorphosis be incomplete until severe experiencing this mortality. Research do in Banjar Penatahan, Bangli regency, Bali. The study design used was completely randomized design (CRD) each treatment was performed 5 replicates where all the data is analyzed by a Single Variant Data Analysis (ANOVA).Giving different concentrations of botanical pesticides, does not describe an increase in mortality green leafhopper. This shows that the power of the pesticide plant is not only focusing on the mortality of insects alone, but also acts as an anti feedant (prevent appetite) and repelant (reject the presence of insects). Neem leaf extract is a very real influence as a pesticide plant in green leafhopper pest control (Nephotettix sp.).

Abstract

The study entitled "The Effect of Dolomite Doses on the Quality and Storage Period of Salak Salak Pasir" has been carried out from April 2019 to January 2020, from the time of dolomite administration to harvest. The study was carried out in farmers' salak gardens in Pajahan Village, Pupuan District, Tabanan Regency and the Agrotechnology Laboratory, Mahasaraswati University, Denpasar. The study was conducted in the field and laboratory using a Randomized Block Design (RBD) with 5 dolomite dosage treatments and 6 replications, so that there were 30 snake fruit plants used in this study. The dosage of dolomite that is applied and is a treatment consists of 5 levels, namely: D0 (0 kg dolomite per tree); D1 (1, 50 kg dolomite per tree); D2 (3 kg dolomite per tree); D3 (4, 50 kg of dolomite per tree) and D4 (6 kg of dolomite per tree). The effect of giving a number of dolomite doses on zalacca plants on the quality and shelf life of zalacca was observed from several parameters namely the parameters of fruit weight, fruit meat weight, seed weight, number of fruit skin scales, fruit flesh thickness and fruit shelf life. Statistical analysis results of the effect of dolomite administration on several parameters observed showed significantly different in the weight of the fruit seeds and very significantly different in the parameters of fruit weight, fruit weight, thick fruit flesh and shelf life of salak fruit. As it is known that dolomite in addition to containing Ca also contains Mg, which has a better effect on soils that have low Mg levels especially for fruit growth and yields From the results of this study it can be concluded that the quality of salak sugar in 1.5 kg dolomite dose significantly higher than the 6 kg dolomite dose; 4.5 kg; 3 kg, and 0 kg dolomite per tree indicated in the fruit meat weight parameters reached 35.06 grams and fruit meat thickness reached 1.02 cm. Giving several doses of dolomite in salak plants are 1.5 kg dolomite doses; 3 kg; 4.5 kg; and 6 kg per tree gives a shelf life of salak sugar which is not significantly different. The shelf life of zalacca sugar is significantly higher than that without dolomite when it occurs in dolomite doses of 1.5 kg per tree which is 13, 50 days. From the conclusion of this study it can be suggested that to improve the quality and shelf life of salak fruit, it is recommended that in salak cultivation be given dolomite 1, 5 kg per tree.

Abstract

Mustard is a horticultural product that is consumed by almost all levels of society everywhere including in Indonesia. Mustard or Caisim (Brassica juncea L.) belongs to the family of Brassicaceae, the leaves are long, smooth, hairless, and not cropped. Hydroponically cultivated plants grow twice as fast as conventional systems. This is due to direct contact between roots and oxygen, optimum acidity, and an increase in the balancing absorption of nutrients and nutrition. D.I.GROW Organic Fertilizer is Liquid Organic Fertilizer made from Ascophyllum nodosum, a type of Chocolate Seaweed taken from the North Atlantic Sea. Naturally, Ascophyllum nodosum, which contains abundant nutrition, such as: Macro Minerals, Micro Minerals, Amino Acids, Humic Acid, Gibberellins, Auxin, Cytokinins and various Nutrition elements needed by all types of Plants and Animals. It used during the Vegetative period. Stimulate and increase the growth of roots, stems, leaves and buds / tillers quickly with the correct dose used for vegetable leaves 3-5 ml / liter of water. The advantages of a hydroponic system are the using of lands does not need to be too extensive, plants are cultivated do not need soil, there is no risk of continuous planting throughout the year, the quantity and quality of production is higher and cleaner, used of fertilizer and the water more efficient, the plants period are shorter, used of pests and diseases more easily and environmentally friendly. Based on the results of the study it can be concluded that the concentration of liquid fertilizer suitable for using in mustard plants in hydroponic media is 3 mL / liter because it has the highest fresh weight above the base of the plant which is 37.78 grams which indicates maximum plant growth. This can be seen from giving of D.I.GROW 3 ml / L fertilizer has the highest plant height, number of leaves, fresh weight above and below of the base of the plant. The nutrients given to plants must be in the right composition. If deficiency or excess, it will be disturbed plant growth and the results obtained are less than optimal. Hydroponic nutrient solutions contain all micro and macro nutrients in appropriate amounts, hydroponic fertilizers are also more stable and dissolve quickly in water because they are in a purer form.

Abstract

Papaya plant (Carica papaya L) is one of the plants whose natural habitat is tropical forests and papaya is also one of the introduced fruit that has long been known and developed widely in Indonesia. The germination of seeds at the beginning of seed formation is very low, but as the age of the seeds increases, which is associated with the accumulation of food reserves, the ability of seeds to germinate increases. The older the seed, the dry matter content in it will be higher. The dry matter content is the accumulation of food reserves formed through the process of photosynthesis. The purpose of this study was to find out where the seeds of papaya plants are located which produce good viability and growth and also to find out from the layout of the seeds (base, middle, tip) the seeds that grow the fastest. The design used in this study was randomized block design (RAK), with treatment of the location of seeds on papaya as many as 3 factors with 9 replications so that the total number of treatments was 27 polybag pots. The treatments were the location of the seeds from the tip (Bu), the middle (Bt), and the base (Bp). The results showed that the treatment of the base (Bp) resulted in a fast growth rate of 13.89 (hst), plant height 14.69 (cm), number of leaves 11.22 (strands), plant fresh weight 7.40 (g) and plant oven dry weight 4.57 (g). ). So from the results of this study the treatment of the base (Bp) which resulted in the best growth compared to the treatment of the tip (Bu) and the middle part (Bt).

Abstract

The population of green leafhoppers Nephotettix virescens, from the nursery to the end of the vegetative phase it needs to be monitored and controlled to avoid and suppress the incidence of tungro. Integrated pest control based on bioecology by suppressing the use of pesticides, suitability of varieties and management of natural enemies has the potential to build a sustainable agroecosystem. The purpose of this study was to determine the pattern of population development of green leafhoppers and various types of predators in several rice varieties so that it becomes important information in determining the types and proportions of varieties, monitoring the density of green leafhopper populations in relation to the incidence of tungro. The study was conducted in Subak Alis Bintang, Sulahan Village, Susut District, Bangli Regency, by using an observation method to determine the presence and development of green leafhopper populations and their predators in IR 66 varieties. The results showed that the pattern of green leafhopper population increased during the vegetative phase (three to six MST) and decreases in the generative phase (seven to eight MST). The level of population density of green leafhoppers is not influenced by the resistance of varieties. In general, the pattern of population density fluctuations of predators does not follow the pattern of population density fluctuations of green leafhoppers in each variety. Based on the index value, diversity of predators above the index value of 0.91 indicates the opportunity for the conservation of natural enemies in biological control by focusing on identifying predatory functional responses to target pests. Therefore also used with various types of potassium fertilizer doses to measure the level of green leafhopper attacks.

Abstract

Environmentally friendly agricultural land management with the use of MOL is able to maintain soil fertility, preserve the environment while at the same time maintaining and increasing soil productivity. Moringa leaf MOL can increase soil nutrients and as a plant growth regulator. This study aims to determine the effect of giving Moringa leaf MOL and the effect of differences in timing of Moringa leaf MOL administration on the growth and yield of mustard greens (Brassica chinensis var. parachinensis L). The study used a Randomized Block Design (RAK) experimental design with 6 treatments and 5 replications. The results of observations at the time of harvesting the fresh weight of harvest and dry weight of harvest also showed that, the treatment of giving MOL at 2 weeks before planting gave the highest real harvested fresh weight and dry weight compared to other treatments. The conclusion from the results of this study is that the difference in the time of giving Moringa leaf MOL to mustard greens gives a significantly different effect on the growth and yield of mustard greens and giving Moringa leaf MOL at 2 weeks before planting on mustard greens gives the yield of fresh weight of harvest and dry weight of harvest. significantly higher than the results at the time of administration of other MOL. So it turns out that the treatment of giving MOL at 2 weeks before planting is the right time for giving Moringa leaf MOL because it can provide the highest real harvested fresh weight and dry weight of harvest compared to other treatments, namely reaching a fresh harvest weight of 9.64 g/plant and a dry harvest weight. 2.20 g/plant.
