Abstract

Limited water availability and soil organic matter are the main causes of low dry land productivity and are the main challenges in efforts to develop them. Green mustard plants, which have a short harvest period and are quite adaptable to the environment, are suitable for development in dry land and are expected to reduce the risk of crop failure due water deficit. One source of organic material that is easily available at the farmer level is cow dung manure. This fertilizer is also able to help provide nutrients, increase the availability of moisture and microorganisms in the soil. It is hoped that the combination of the use of cow dung manure with mustard plants can be an afternative solution and efforts to increase the productivity of dry land. The research aims to determine the possibility of using cow dung as a source of organic fertilizer in the cultivation of green mustard on dry land. The research is based on a Randomized Block Design consisting of nine treatments with four replications. Treatments included a combination of different ages of seedlings without cow dung manure as a control; difference in seed age with 7.5 tons Ha-1 of cow dung manure and difference in seed age with 15 tons Ha-1 of cow dung manure. The data obtained were analyzed using variance and if there were significant differences, it was continued with the HSD test at the 5% level. The research result showed that applying cow dung manure can increase the growth and yield of green mustard on dry land. Seedlings aged 10 days after showing combined with the addition of 15 tons Ha-1 of cow dung manure can produce a fresh weight of 21.15 tons Ha-1 or 95.56% of the average potential productivity

Abstract

The increasing demand for broiler chickens occurs because the shift in people's consumption patterns from food sources of vegetable protein to food sources of livestock protein is expected to continue to increase and continue in the future. One of the factors that can influence the success of broiler chicken production is external factors, where external factors include chicken seeds (DOC), death/mortality rates, feed, labor and marketing. The aim of this research is to find out whether external factors of breeders have an influence on broiler chicken production in Gianyar Regency, Bali Province and to find out what indicators of external factors of breeders have the most dominant influence on broiler chicken production in Gianyar Regency, Bali Province. The population of this study were all broiler chicken breeders who live in Gianyar Regency, Bali Province. The number of samples for this research was 57 samples taken using the purposive random sampling method. The design used in this research was a survey method. In this research, the data collection method used was a questionnaire. Data collection was carried out by means of interviews, observations and questionnaires. The collected data was analyzed using qualitative descriptive analysis. The research results show that from the T test results, DOC (X1), Feed (X3), Labor (X4), and Marketing (X5) which are indicators of the External Factor variable (X) are proven to have no significant effect on the Broiler Chicken production variable ( Y). And the mortality rate indicator (X2) is the most dominant indicator and has a significant effect on Broiler Chicken Production (Y).

Abstract

Increasing the productivity of Pakcoy plants which have good quality and high yields requires providing nutrients to the plants such as fertilization. Fertilizers that can be used are goat manure and NPK fertilizer. This research aims to determine the optimal dose of goat manure and NPK fertilizer to increase the growth of Pakcoy plants. This research used a factorial randomized block design consisting of two treatment factors. The first factor is goat manure (PK) which consists of four levels, namely 0; 0.5 ; 1 and 1.5 kg/polybag. The second factor is the concentration of NPK fertilizer which consists of four levels, namely 0; 1 ; 2 and 3 g/polybag. Observed variables included: Maximum plant height (cm), Number of Planting Leaves (Strands), Fresh weight of economic yield per plant (g), Total plant weight (g), Oven dry weight of Stove (g), Fresh weight of stover (g) , and oven dry weight of economic yield per plant (g). The experimental data were analyzed statistically using analysis of variance according to the design used. If the treatment has a significant or very significant effect, continue with the average value difference test using the 5% BNT test method. The results of the research showed that giving a dose of goat manure had a very significant effect (P<0.01) on the total weight of the plant and the economic fresh weight of the pak choy plant. The NPK dosing treatment had a significant effect (P<0.05) on the dry weight of the economical oven. The interaction between treatments of providing doses of goat manure and NPK had no significant effect on the growth of pakcoy plants. The highest economic fresh weight of pak choy plants was obtained in the treatment of providing goat manure at a dose of 1 kg/polybag with a fresh weight percentage of 83.36% and NPK fertilizer at a dose of 2 g/polybag with a fresh weight percentage of 85.27%.

Abstract

This study aims to determine the interaction of Bokasi Fertilizer and Atonic Growth Regulators on the growth of tomato plants. This research was conducted in the greenhouse of the Faculty of Agriculture, Warmadewa University, JI. Ompong 24 Tanjung Bungkak, Denpasar with a height of 25 m above sea level. This research starts from August - October 2023. This experiment uses a factorial pattern Group Randomized Design (RAK) with two factors, namely: Factor I is atonic ZPT with 4 levels of concentration, namely: A0 = 0 cc 1-1, A1 = 1 cc 1-1, A2 = 2 cc 1-1, A3 = 3 cc 1-1, Factor II is bokashi fertilizer consisting of 4 concentrations, namely: B0= 0 tons / ha, B1 = 10 tons / ha, B2 = 20 tons / ha, B3 = 30 tons / ha, Thus there are 16 combination treatments, each of which is repeated 3x so that there are 48 experimental polybags. The treatment of atonic growth regulators 1 cc 1-1 tends to give the highest dry weight yield of 148.68 grams, which is not real from other treatments. The treatment of 30 tons / ha of bokasi fertilizer tends to produce the highest dry weight of 149.44 grams which is not real from other treatments. Bokasi fertilizer has a real effect (P<0.05) on the fruit diameter and no real effect (P>0.05) on other variables. The treatment of bokasi fertilizer of 30 tons / ha produces the highest fruit diameter of 3.49 cm which is not real with the treatment of fertilizer 0 tons / ha and 20 tons / ha with fruit diameters of 3.31 cm and 3.40 cm respectively, but differs markedly from the application of bokasi fertilizer of 10 tons / ha with a fruit diameter of 3.10 cm. Bocation fertilizer tends to show no real influence on the growth and yield of tomato plants which is likely due to goat manure bokashi fertilizer has not been absorbed by tomato plants optimally.
