Abstract

The research was purposed to know the influence concentration of liquid organic fertilizer and shade intensity to growth of robusta coffee seedlings. Research was conducted in Cibeureum, Cilimus, Kunigan district. Research was conducted on January – May 2018. The experimental metode used is split plot design, which consist two factors. First factor is the shade intensity which consist of level that are shade 50% (N1), shade 75 % (N2) and shade 95 % (N3). The second factor is concentration of liquid organic fertilizer consist 3 level, 0 ml/l water (P1), 400 ml/l water (P2) and 800 ml/l water (P3). All of treatments were repeated 3 times, that there are 27 experimental unit. The observation variables were increase in plant height, increase in leaf number, increase in stem diameter, root volume and dry weight of plants. The date observation result then do analysis of variance test F real level 5%. if there is a real difference, then the test continued with Least Significance Different on level 5%. The result showed that there was an interaction between giving concentration of liquid organic fertilizer and shade intensity to parameters of the average yield of plants aged 60 HSPT and dry weight of plants. In additin, this treatment independently affects the parameters of the average yield of plants 30, 90 and 120 HSPT, the average increase in stem daimeter od 60, 90 and 120 HSPT, and the average root volume.

Abstract

This experiment aims to determine the effect of spacing and nitrogen fertilizer on the growth and yield of sorghum (Sorghum bicolor L. Moench) Samurai 2 variety. The experiment was carried out in Mekarjaya Village, Gantar District, Indramayu Regency - West Java. The time of the research was carried out from July to November 2021. The location is located at an altitude of 493 m above sea level (asl), the soil type is the association of Latosol and Regosol, including type C rain (slightly wet). The experimental method used is the experimental method with a factorial randomized block design (RAK), the treatment consists of two factors, repeated three times. The first factor is nitrogen fertilizer which consists of three levels, namely 100 tons/ha nitrogen fertilizer, 150 tons/ha nitrogen fertilizer, and 200 tons/ha nitrogen fertilizer. While the second factor is the spacing which consists of three levels, namely the spacing of 25 cm x 40 cm, the spacing of 25 cm x 50 cm, and the spacing of 25 cm x 60 cm. The main observation data were processed using linear model statistical tests, analysis of variance, and Scott-knot cluster further test analysis. To determine the correlation between the treatment with the components of growth and yield of sorghum, the correlation used is the Product Moment correlation coefficient. 1 The experimental results showed: (1) The combination of plant spacing and nitrogen fertilizer had an effect on leaf area index at 28 HST, 35 HST and 42 HST, and panicle length, but had no significant effect on plant height, number of leaves, stem diameter, root volume, number of panicles per clump, panicle weight per clump, 1000 seed weight, seed weight per clump and dry seed weight per plot, (2) The highest seed weight per plot was produced by the combination of treatment G, namely 25cm x 60 cm spacing and 100 kg urea fertilizer with an average The average weight was 3.79 kg (equivalent to 6.314 tons/ha), but it was not significantly different from the other treatment combinations, (3) There was a significant correlation between plant height at 42 HST and seed weight per plot in the tall category. However, there was no significant correlation between plant height at 28 HST (very low category) and 35 HST (low category) and the number of leaves at 28 HST (very low category), 35 HST (very low category) and 42 HST (very low category). low category) with dry seed weight per plot

Abstract

This study aims to determine the influense of the type of manure and the age of seedlings on the growth and yield of cayenne pepper plants (Capsicum frutescent L). This research was conducted in Bayalangu Kidul Village, Subdistricts of Gegesik, District of Cirebon – West Java, from March until Juny 2018. The Method used to experimental method using a Rendomized Blok Design patterns, treatment consists of two factors were repeted three times. The first factor is a type of manure consists of chicken manure, goat manure and cow manure. While the second factor is age of seed consists of age of seed 20, 30 and 40 days after seedling. The results of the study showed the real difference between types of manure and age of seedlings against plant height, number of leaves, number of fruit cropping and planting as well as fruit weight cropping and planting. On the treatment A (chicken manure and 20 days after seedling), B (chicken manure and 30 days after seedling), C (chicken manure and 40 days after seedling), E (goat manure and 30 days after seedling) and F (goat manure and 40 days after seedling) increase the weight of the fruit.

Abstract

This research aims to determine the effect of chicken manure and NPK on the growth and yield of shallot plants (Allium Ascalonicum L.) Sumenep cultivar. The research was carried out in Lengkong Village, Garawangi District, Kuningan Regency, in November – February 2024. The research method used was a randomized block design (RAK) with a paktorial pattern. The treatment consisted of two factors which were repeated three times. The first factor is chicken manure which consists of four levels, namely 0 tons/ha, 5 tons/ha, 10 tons/ha and 15 tons/ha, while the second factor is the dose of NPK fertilizer which consists of three levels, namely 50 kg/ha. , 75 kg/ha, and 100 kg/ha. The results of the research showed that the Chicken Manure and NPK treatments did not provide a real interaction with all treatments, but had an independent influence from 100 kg/ha NPK fertilizer on plant height at 28 DAT and 35 DAS, number of leaves at 28 DAS and 35 DAS, there was also an effect independently from the treatment of 10 tonnes/ha of chicken manure on tuber diameter. Treatment with a dose of chicken manure at a dose of 15 tons/ha gave the best results in dry tuber weight per plot, namely 1.68 kg/plot, equivalent to 6.22 tons/ha and an NPK dose of 100 kg/ha gave the highest results in dry tuber weight per plot. plot, namely 1.65 kg, equivalent to 6.11 tonnes/ha.

Abstract

This research aims to determine (1) Interaction of humic acid and nitrogen application on growth, yield, and quality of shallot (2) To determine the effect of the combination of nitrogen fertilizer and humic acid and determining the right dose for the growth, yield, and quality of shallot. This research was conducted in Kuningan which is located in Lengkong Village, Garawangi District, Kuningan Regency, West Java Province. The research location has an altitude of 600 meters above sea level, average temperature of 180C to 320C, and an average rainfall of 1,433.6 mm/year. This research was conducted from November 2023 to January 2024. The method used is the experimental method with a Randomized Group Design (RAD) factorial pattern. The treatment consisted of 2 factors, the dose of humic acid and the dose of nitrogen fertilizer. The dose of humic acid consisted of four levels: A0 = Control (Without Humic Acid), A1 = 2 kg / ha, A2 = 4 kg / ha, and A3 = 6 kg / ha. While the treatment of nitrogen fertilizer dose consisted of four levels: N1 = 25% of the recommended dose (urea 62.5 kg / ha), N2 = 50% of the recommended dose (urea 125 kg / ha), N3 = 75% of the recommended dose (urea 187.5 kg / ha), N4 = 100% of the recommended dose (urea 250 kg/ha). From these two factors, 16 treatment combinations were obtained and repeated 2 times, so that overall there were 32 experimental plots, in each experimental plot 5 plants were selected as sample plants. Based on the results of the research and discussion, the following conclusions are: 1 (a) The dose of humic acid and nitrogen fertilizer gave a significant interaction effect on variables of root crown ratio, bulb volume, fresh bulb weight/plant, fresh bulb weight per plot, sun-dried tuber weight per clump, sun-dried tuber weight/plot, bulb weight loss and bulb dissolved solids. (b) Humic acid gave a significant effect on all variables, except for weight loss and water content. The dose of nitrogen fertilizer gave a significant effect on all observation variables except for the water content observation variable.
