Abstract

Sugar production has decreased due to the fertilization method. One solution is to apply the proper dose of fertilization. The purpose of this study was to determine the application of various doses of foliar fertilizer on the growth and yield of the JR 01 variety at the age of 7 months burned in Gresik Regency. This study used a Randomized Block Design with one factor, namely P0 (control), P1 (cow urine fertilizer 20 ml/liter), P2 (cow urine fertilizer 40 ml/liter), P3 (cow urine fertilizer 60 ml/liter), P4 (Petrovita fertilizer 3 ml/liter), P5 (Petrovita fertilizer 6 ml/liter), and P6 (Petrovita fertilizer 9 ml/liter). Each was repeated four times so that there were 28 experimental units with observation variables, including growth variables (increase in stem height, stem diameter, number of stems, number of segments, number of tillers) and yield variables (Brix, yield, weight per cane stalk (g plant-1) and weight per cane stalk (t ha-1). Observational data were then analyzed using analysis of variance (ANOVA). If there was a significant difference, proceed with the Least Significant Difference test (LSD) 5% and correlation test. In the growth variable, the highest significant differences were between ages 44, 46, and 48 weeks after planting (WAP) and the use of cow urine fertilizer on the variable number of tillers. While in the yield variable, there was the highest significant difference at the age of 44 WAP using petrovita fertilizer on the Brix and yield variables. There was a significant correlation with a very strong and unidirectional relationship between the growth and yield variables. Effective treatment in increasing growth in the number of tillers, namely P2 (cow urine fertilizer 40 ml/liter), effective therapy in increasing Brix yield, and the yield is P5 (Petrovita fertilizer 6 ml/liter).

Abstract

Goldfish (Carassius auratus) is an ornamental fish with promising agribusiness prospects. One of the cultivation areas with potential for development is Tulungagung Regency. The research was conducted at the Fish Cultivation Group (Pokdakan) Tirto Mulyo Asri, located in Wajak Lor Village, to analyze a particular approach to escalating goldfish culture in the area. The study adopted the Force Field Analysis (FFA) method with a qualitative descriptive analysis approach. The analysis showed five factors driving and inhibiting goldfish cultivation at the research site. The highest driving factor is consumer demand, while the highest inhibiting factor is bad weather conditions, namely the transition season (seasonal shift). The key success factor based on the driving factors for elevated consumer demand means that it focuses on maintaining consumer confidence in the products produced. On the other hand, the key success factor in overcoming the inhibiting factors for bad weather conditions or the transitional season is focusing on weather prediction through collaboration with the government, such as the BMKG. The best approach to halting goldfish culture in the Tirto Mulyo Asri Tulungagung Fish Cultivation Group is to maximize the key driving factors and minimize the key inhibiting factors.

Abstract

Fertilizer plays an important role in plant growth and yield. Shallot (Allium ascolocium L.) in its production process utilizes various types of fertilizers to achieve optimal production goals. In recent years, shallot has become a favorite commodity for farmers in Kediri Regency to cultivate because of its promising agribusiness prospects. The main problem for farmers is the diverse use of fertilizers depending on the availability and experience of farming alone. Based on these considerations, the study was conducted on a group of shallot farmers in Kediri Regency to analyze the effect of fertilizer type on production. Multiple regression analysis was employed in this study with independent variables, namely Za, Urea, Manure, KCl, Nitrophoska, Mutiara, Patent-Kali, and Fertiphos fertilizer, while the dependent variable was shallot production. The results showed a significant effect between the utilization of various fertilizers on the production of shallot. However, the use of most types of fertilizers for production, individually, did not affect the production of shallot. Only KCl and Mutiara fertilizer significantly affected the production of shallot. The addition of the use of KCl and Mutiara fertilizer had an impact on changes in the amount of shallot production.

Abstract

Zea mays saccharata or sweet corn has become a leading horticultural commodity. It is not only limited to vegetables that are consumed normally but come with a variety of preparations. Therefore, there is a need for research on sweet corn productivity due to the interaction effect of herbicide spraying time treatment and plant spacing. In this study, sweet corn seed planting materials of TALENTA variety and selective herbicide PAG (Anti-Weed Package) were used with the active ingredients of Atras 600 sc and Aleron 60 sc. The research was carried out using the RAK environmental design (Randomized Block Design) with 3 replications and 2 treatment factors, namely 3 levels of spacing and herbicide spraying time which also consisted of three levels. Observations using destructive and non-destructive methods. By observing the variables of plant height, the number of leaves, stem diameter, leaf width, length of ear, the weight of ear, and diameter of the ear. The data obtained from the observational variables were processed by the F test using the ANOVA method. If there are treatments that are significantly different, a 5% Least Significant Difference test will be carried out. Planting distance J2: 70 x 30 cm and spraying herbicide PAG at P2:14 DAP was the best spacing and spraying time for sweet corn cultivation. Optimal spacing and proper spraying time can reduce the level of competition between cultivated plants and cultivated plants with weeds.

Abstract

In increasing the production and quality of rice plants, it is essential to pay attention to proper nutrient management. One of the most important nutrients in increasing rice production and quality is magnesium, tested with deficiency and toxicity treatments in subsoil soils. This study used a factorial randomized block design with two factors where each treatment was repeated three times. First factor included Nutrient toxicity Mg, T0 = 0 (control), T1 = 2.2 g/polybag, T2 = 4.4 g/polybag, T3 = 8.8 g/polybag. Second factor included Mg nutrient deficiency D0 = 0 (control), D1 = 0.56 g/polybag, D2 = 0.28 g/polybag, and D3 = 0.14 g/polybag. The results showed that the deficiency treatment significantly affected plant height 5-6 weeks after fertilization and leaf chlorophyll 9 WSP. In contrast, the toxicity treatment significantly affected Total Chlorophyll 4 MSP and 1000 grain weight, where the D2 and T2 treatments showed the highest data. This study explained that the D2 and T2 treatments showed good plant responses. The red sigambiri variety was quite tolerant of magnesium deficiency and toxicity treatments.
