Shallots are a horticultural crop that is very important for society. One effort to increase production is by providing Banana Weevil POC. This research aims to determine the effect of planting media and liquid organic fertilizer from banana weevil (Musa sp.) on the growth and yield of local varieties of shallot plants (Allium cepa L.). This research was carried out on residential land located at Bendorejo Hamlet, Bendosewu Village, Talun District, Blitar Regency. In April-June 2023. The research was prepared using (RAK) factorial with two factors, namely the composition of the planting media (M) and the concentration of Banana Weevil POC (D), with each treatment having 3 replications. Observations were made after the plants were 7 days after planting, with an observation interval of 14 days. The observation parameters include plant height, number of leaves, number of tubers, and tuber weight. The results of the research showed that the combination treatment of cow dung and Banana Weevil POC with a concentration of 10 ml had a significant effect on plant height, number of tubers and tuber weight. However, it has no effect on the number of leaves.

The aim of the research was to determine whether there was a real interaction effect of Azolla POC concentration and the time interval of POC administration on the yield and growth of Pakcoy plants. The research used a Randomized Group Design (RAK) arranged factorially including 2 factors which were repeated 3 times. Factor I is the nutrient dose of Azolla liquid organic fertilizer which consists of 3 levels 4 namely D1: 0 ml/1 water, D1: 2 ml/l water, D2: 4 ml/l water, D3: 6ml/l water and Factor II is Time interval for application of 3 level Azolla liquid organic fertilizer. S1: Application time interval 2 days, S2: Application time interval 4 days, S3: Application time interval 6 days. Plant height (cm) was observed at 0, 7, 14, 21, 28, 35 HST, measured using a meter. The number of leaves at 1, 3, 5, 7 and 9 WAP and leaf width at 0, 7, 14, 21, 28, 35 HST were measured using a tape measure. Accumulated fruit weight per plant (grams) The wet fruit weight of Pokcoy plants is determined by weighing all parts of the plant (roots, stems, leaves). Plants were weighed one by one using an analytical balance. Observational data were analyzed using Analysis of Variance (ANOVA) with a level of α = 0.05 and if there were significant differences between treatments then a further test was carried out using the DMRT test (Duncan's Multiple Range Test) at a level of α = 0.05. The results of research that have been carried out have concluded that there is a real interaction between the concentration of Azolla liquid organic fertilizer (D) and the time interval for POC application on the growth and yield of Pak Choy plants. The best treatment combination for plant height variables; number of leaves; leaf area is the D2S2 treatment, namely the combination treatment of azolla POC concentration of 4 ml/L and the POC application time interval of 4 days, while for plant fresh weight the best combination is D2S3, namely the combination treatment of 6 ml Azolla POC concentration and 4 day POC application time interval with weight. fresh plants amounting to 58.17 grams.

The aim of the research is to determine the effect of differences in melon cultivation in two greenhouse construction designs which provide the best results on the growth and yield of melon plants (Cucumis melo L.). The research was conducted from July to September 2022 at the Balitar Islamic University of Blitar Greenhouse. The design used is a dependent analysis method which tests the relationship between independent variables. The analysis technique used is the parametric t-test. The t-test difference test was carried out on two category groups with the condition of two paired sample groups (paired sample t-test). The variables observed were plant height (cm), number of side shoots (strands), stem diameter (cm) and fresh fruit weight (gr). The results showed that the Greenhouse 1 (GH1) design provided an agro-climatic environment that was more in line with the environment needed by the melon plants significantly compared to the GH2 design so as to provide better melon plant growth and better yields. The average fruit fresh weight for melon plants cultivated in GH1 was 1008.52 grams of side shoots which was significantly better than in GH2 which was 968.32 grams.

The aim of this research is to determine the effect of the interaction between planting media composition and dosage of Nasa liquid organic fertilizer on the growth and yield of eggplant (Solanum melongena L) var. YuvitaF1. The research was carried out in Dukuh Jlimut, Plosokerep Village, Sananwetan District, Blitar City with an altitude of 150-200 in March – June 2023. The research used a 2 factorial Randomized Block Design. Factor I is the composition of the planting medium (M) which consists of 3 levels, namely M1: soil: Goat kohe fertilizer (5:1), M2: Soil: Rice husks: Goat kohe (3:2:1), M3: Soil: Cocopeat : Kohe Goat (3:2:1). Factor II is the dose of Nasa POC fertilizer (P) which consists of 4 levels, namely P1 = 0 ml/polybag (without POC fertilizer), P2: 3 ml/polybag, P3: 6 ml/polybag and P4: 9 ml/polybag . The experiment was repeated 3 times so there were 36 experimental units. The variables observed were plant height (cm), number of fruit and fruit weight at harvest (grams). The average observation results were analyzed using a variance test (α = 5%) and followed by a 5% Honestly Significant Difference Test (BNJ). The research results showed that there was a real interaction between the composition of the planting medium (M) and the Nasa POC dose (P) on the variables of plant height, number of fruit and fruit weight of eggplant plants. The best results were obtained in the M1 planting media composition treatment (soil: goat kohe with a ratio of 5:1) and a Nasa POC dose of 6 ml/polybag (M1P3) for these 3 variables.

Fertilizer is a supporting component in the agricultural sector which has the most important role to improve agriculture in Indonesia, this happens because farmers realize that the role of fertilizer greatly influences agricultural yields. Farmers' dependence on fertilizers is getting bigger when the government succeeds in developing agriculture through food self-sufficiency. The need for agricultural production continues to increase along with the increasing rate of population growth, resulting in the need for fertilizer also increasing. This situation forces fertilizer producers to produce optimally in order to meet market demand. This study aims to explain the strategy for distributing subsidized fertilizers in Wonotirto District so that it can help farmers in terms of providing subsidized fertilizer according to the needs of farmers and according to what has been determined in the RDKK (Definitive Plan for Group Needs).

This study aims to determine the interaction of NPK fertilizer and cow urine on the growth and yield of cucumber plants. To determine the best dose of NPK fertilizer on the growth and yield of mentimub plants, to determine the dosage of cow urine that is suitable for the growth and yield of cucumber plants. This research was conducted using factorial randomized block design (RBD) with 2 factors, the first factor was the dose of NPK fertilizer (N) consisting of 3 levels, namely 250 kg / ha (N1), 350 kg / ha (N2) 450 kg / ha (N3). The second factor is a cow urine dose of three systemf, namely: 300 ml / plot (U1), 400 ml / plot (U2), 500 ml / plot (U3). The observed variables include leaf area, diameter stem, fruit length, amount of fruit, and fruit weight. Data were analyzed using variance analysis (ANOVA) level of 5% and further testing with Duncan's Multiple Range Test (DMRT). The results showed that: There was no real interaction between NPK doses and cow urine fertilizer on the growth and yield of cucumber plants. The treatment of NPK fertilizer dose of 250 kg / ha (N2) significantly affected the length of the fruit. The best length of fruit yield was 20,7033 cm 2 harvest age 51 HST and the best fruit yield weight was 450 kg / ha amounting to 3367.11 g. in all harvests.
