Abstract

Soil microorganism activity is inhibited during the dry season, especially in dry land. Mulching is one of the efforts to maintain soil moisture and microorganism activity. This study aims to examine the growth response plant edamame against the use of mulch straw and application PGPR (Plant Growth Promoting Rhizobacteria). Conducted from July to September 2024 in Kaliurang Village, Jember with an altitude of 146 meters above sea level. This experiment was designed using factorial RAK consisting of two factors and three replications. Factor First that is concentration PGPR Which consists of from 0 ml/l (control), 12.5 ml/l and 25 ml/l, while the second factor is the thickness of straw mulch consisting of 2.5 cm, 4.5 cm, And 6.5 cm. Results study This show existence interaction from PGPR And mulch straw on treatment mulch 6.5 cm + 12.5 ml/l with tall 17.30 cm 24 HST. In the treatment (4.5 cm + PGPR 12.5 ml/l) it influenced the height plant age 32 HST (23.00 cm), amount pod per sample 20.13 pod and biomass dry18.53 g, whereas amount branch per sample on treatment (0 ml/l + 6.5 cm) 1.93 branches. However, the weight of pods per sample and the weight of pods per plot did not happen interaction. Heavy pod per sample on concentration 25 ml/l (55.02 g), at a mulch thickness of 4.5 cm (54.31 g). Pod weight per plot 1255.89 g (25 ml/l) and 1253.22 (4.5 cm). Use mulch straw allegedly capable guard humidity soil so that the microorganisms in PGPR are able to grow well and activity microorganisms in a way can directly influence growth and edamame crop yields.

Abstract

The importance of good nutritional intake has led to a high demand for mung beans. One of the efforts to increase mung bean production through the application of Gamal Leaf Liquid Organic Fertilizer. This study aims to examine the growth response and production of mung beans through the application of Gamal Leaf Liquid Organic Fertilizer. This research was carried out on agricultural land in Antirogo Village, Jember Regency from June to September 2024. This study consists of 6 levels of treatment, namely: Without Gamal Leaf Liquid Organic Fertilizer, Gamal Leaf Liquid Organic Fertilizer 40 ml/l, Gamal Leaf Liquid Organic Fertilizer 60 ml/l, Gamal Leaf Liquid Organic Fertilizer 80 ml/l, Gamal Leaf Liquid Organic Fertilizer 100 ml/l, Gamal Leaf Liquid Organic Fertilizer 120 ml/l. The results of this study showed that the application of Gamal Leaf Liquid Organic Fertilizer 120 ml/l had a real effect on the number of sampled pods (52.25 seeds), the weight of wet pods per sample (44.95 grams) and had a very real effect on the weight of perplot dry seeds (608.5 grams), the weight of sampled dried seeds (41.40 grams).

Abstract

Cowpea is one of the food crops that has a fairly high protein content, but the production of cowpea is still relatively small. The cultivation technology applied is still not right, so that cowpea production does not increase. This study aims to determine the effect of applying several PGPR concentrations on the growth and production of cowpea. This study was conducted on the land of the Jember State Polytechnic from July 2024 to October 2024. This study used a Non-Factorial Randomized Block Design (RBD) with 6 treatments and 4 replications. Observation data was analysed statistically using Analysis of Variance (ANOVA). The treatments were PGPR concentrations of 0 ml/L, 18 ml/L, 29 ml/L, 40 ml/L, and 51 ml/L. The results showed that PGPR treatment with a concentration of 51 ml/L showed a difference in plant height, dry seed weight per plant, and 100 seed weight per plot. This is thought to be due to the role of PGPR as a biofertilizer and bio stimulant. Thus, PGPR can provide nutrition and produce growth hormone. This will have an impact on fulfilled the nutritional needs of cowpea, thus affecting the growth and production of cowpea.

Abstract

The decreasing trend in peanut productivity in Indonesia over the years is primarily linked to soil degradation resulting from the overuse of synthetic fertilizers. Therefore, it is necessary to apply environmentally friendly methods such as liquid organic fertilizer and pruning to optimize peanut productivity. This research aimed to examine the influence of bamboo shoot liquid fertilizer and pruning time on peanut production. The research was conducted in Antirogo Villcommunity age, Sumbersancy during the period from July to October 2024. Using a Randomized Block Design with two factors. The first factor was the concentration of bamboo shoots liquid fertilizer namely P0 (0 ml/L), P1 (100 ml/L), and P2 (200 ml/L). The second factor was W0 (shoot pruning time which consisted of control), W1 (7 days after flowering), and W2 (14 days after flowering). The results imply that the results indicated that the concentration of bamboo shoots liquid fertilizer of 100 ml/L has a significant effa notable example fresh shoot weight per-sampel. In addition, the shoot pruning treatment conducted 7 days after flowering had a notable effect on the fresh pod weight per-sample. Based on the interaction between the two factors, it has an effect on fresh pod weight per sample, dry pod weight per sample, dry seed weight per sample, and dry seed weight per plot.

Abstract

Corn is one of the food crops in Indonesia that has great potential to be developed, one of which is pulut corn. Pulut corn itself is corn with a high amylase content, but the yield of this corn is in the low category. One way to increase the productivity of pulut corn is the use of liquid organic fertilizer made from tofu waste. The research was carried out on the Jember State Polytechnic land in July-October 2024. Using RBD, which consists of a single treatment, namely the concentration of tofu waste. There are six treatment levels, including control, 26 ml/l, 28 ml/l, 30 ml/l, 32 ml/l, and 34 ml/l. The results of the observation parameters will be tested further with BNJ. From the six levels of treatment given, it was found that treatment with a concentration of 34 ml/l could reduce the stem diameter at 21 DAT, the weight of corn cobs per sample. A concentration of 30 ml/l affects the diameter of the cobs, while a concentration of 32 ml/l affects the weight of the cobs per plot. The parameters of plant height and biomass weight provide significant ups and downs.
