Abstract

The objectives of research were to identify the effects of light intensity to the growth and anatomy of Salvinia molesta. Research was conducted in Nanggulan Maguwoharjo, Depok, Sleman with altitude of 113 m asl. The materials were Salvinia molesta, vertisol soil, and urea. The investigation parameters were: the time of initial leaf emerge, number of leaves, diameter of leaf, the length of internodes, length of root, dry weight of plant, percentage of coverage, ratio of root/canopy, rate of relative growth, number of stomata, number of trichoma, the thickness of cuticle and leaf chlorophyll. The results showed that the growth of Salvinia molesta was affected by light intensity. Highest dry weight was gained with light intensity of 100%. The rate of initial growth increased at the age of 14 up to 28 days, but number of stomata and trachoma. Highest chlorophyll content was on the treatment of 25% light intensity

Abstract

To ensure the fulfillment of quality seed varieties ongoing basis in order to support increased production and productivity of rice plants, the use of quality seeds of improved varieties to suit every taste quality of farmers / seed users is worth noting. The new variety is declared superior and deserve to be disseminated if it has been released officially by the government. One of the requirements in the proposing release varieties are strains / mutants / hybrids / clones that have made adaptations proposed release of varieties, it is intended to determine the production potential and the ability to adapt to various environments, and it is known that environmental conditions appropriate notice of its development. Thus, the objectives of the adaptive test is to determine the production potential, agronomic characteristics and advantages of the strain / mutant / hybrid / clone in adjusting to the growth environment. This study aimed to evaluate multiple strains of rice paddy to the state of the environment in the production center of the village of Hoku-Hoku Kie, District Jailolo-West Halmahera district. This research used Randomized Block Design (RBD) a single factor using 7 strains are: OBS 1711/PSJ, OBS 1712/PSJ, OBS 1713/PSJ, OBS 1714/PSJ, OBS 1718/PSJ, OBS 1719/PSJ, OBS 1720/PSJ , and 3 varieties for comparison, namely Cimelati, Ciherang, and IR 64. The results demonstrate the ability of adaptation to the environment from several strains tested, strain OBS 1718/PSJ a strain that is able to adapt to the environment in Production Centers Hoku - Hoku Kie West Halmahera District JailoloKeywords: rice strain, environmental adaptation

Abstract

The research was to determine the best combination of Chrysanthemum explant and concentrations of BAP (6 - benzyl amino purine), the effect of the explant material and the effect concentrations of BAP (6 - benzyl amino purine) in vitro culture by Murashige and Skoog medium. The experimental methode was Completely Randomizes Design (CRD) which consisted of two factors. The first factor is the explant material, consisting of three standards are: P1 = node, P2 = shoots, P3 = leaf. The second factor is the concentration of BAP which consists of four levels, namely: B1 = 0.5 ppm, 1.0 ppm = B2, B3 = 1.5 ppm, B4 = 2.0 ppm. The results showed there were significant interaction on fresh weight, dry weight, number of shoots and length of shoots. The treatment combination between bud explants with BAP 0.5 ppm, showed the best results on fresh weight, number of shoots and long shoots. Use of explant shoots, can accelerate the current growth of shoots, expanding the number and length of root buds. The addition of plant growth regulators BAP 0.5 ppm in the tissue culture medium, can spur the rapid growth of shoots, root number and length of root best.Key words : in vitro, chrysanthemum, kinds of eksplant, the concentration of BAP

Abstract

The research aims to examine the potential of a land for the development of lowland rice crop, to analyze land cultivation system to support the growth and production of rice crop. Physical examination on land is conducted using survey method with rigid grid observation distance. Economical aspects related to the examined farm are: (1) farm profit, (2) R/C ratio analysis, and (3) Break Even Point (BEP) analysis. Research result shows that the actual potential of the rice field resulting from conversion of sago land has low nutrient (N total, available P2O5, and K2O) availability. Result from rice farm analysis shows that the average area is 2.700 m2 , with average production is 699 kg or 0,26 kg m-2 or equal to 2.586,30 kg Ha -1 . The average net income is Rp. 2,660,333,-. The farm is feasible to be developed with R/C ratio value of 4,72. Rice farming with area of 2.700 m2 will break even if the income gained by farmer is Rp. 315.928 per season, production of 52,93 kg per season, or sold result of Rp. 1.482 kg -1 on area of 204,66 m2 .Keywords: Land potential, land evaluation, farm analysis

Abstract

A research on the effect of shading and fertilizer on nitrate content and the growth of spinach (Amaranthus sp) has been done at the experimental field of Agriculture Faculty, from October to November 2010. It was located in Batikan, Yogyakarta Special Territory. The study was intended to find out the effect of plastic shading and kind of fertilizer and its interaction on nitrate content and the growth of spinach. The experiment was a split plot, arranged in a completely randomized design. The main plot was shading which is consisted of two levels i.e. without shading and plastic shading. The main plots split into four different kind of fertilizers applied namely: urea, compound fertilizer NPK, manure, and compost. The result showed that the used of plastic shading gave higher nitrate content in spinach compared to open air, while plans with compost application have better growth than others.Keywords: plastic canopy, fertilizer, nitrate content, spinach,
