PENGARUH APLIKASI HERBISIDA TUNGGAL DAN CAMPURAN TERHADAP PERTUMBUHAN DAN HASIL TANAMAN JAGUNG (Zea mays L.) DI LAHAN KERING

Nopit Yohanes — 2024-04-22

This research aims to find out which herbicide application has the best effect on the growth and production of corn plants (Zea mays L.). This research used a non-factorial Randomized Block Design (RAK) consisting of one treatment factor with 8 treatment combinations and 3 replications, so there were 24 treatment combinations. Single and mixed herbicide treatments consisted of P₀ (no weed control), P₁ (mechanical control), P₂ (atrazine herbicide), P₃ (saflufenacil herbicide), P₄ (nicosulfuron herbicide), P₅ (atrazine + saflufenacil herbicide), P₆ (atrazine herbicide + nicosulfuron) and P₇ (herbicide atrazine + saflufenaci + nicosulfuron). The parameters observed in this study included the level of plant poisoning, flowering age (DAP), harvest age (DAT), cob weight per plot (kg), seed dry weight per plant (g). The research results showed that P5 treatment (herbicide atrazine + saflufenacil) could accelerate flowering time, harvest time, increase ear weight per plot and seed dry weight per plant, and the herbicide treatment did not result in poisoning of corn plants.

Keyword: control, herbicides, corn.

MODIFIKASI UNSUR HARA SULFUR TERHADAP KARAKTER TANAMAN BAWANG MERAH (Allium ascalonicum L.) DI BUDIDAYA TERAPUNG

Novikar — 2024-04-22

Floating cultivation is a system created as an innovation that is able to overcome agricultural problems in areas with a geographical location of water. This research aims to determine the effect of sulfur nutrient modification on the characteristics of shallot plants (Allium ascalonicum L) in floating cultivation. The research was carried out in May 2023 at the research pond of the Faculty of Agriculture, Sriwijaya University. The method used in this research was a completely randomized design with sulfur applications including: S1 (0 kg ha-1), S2 (30 kg ha-1), S3 (60 kg ha-1), S4 (120 kg ha-1). 1), S5 (240 kg ha-1). Parameters observed in this study included leaf length (cm), number of leaves (strands), number of tillers (clumps), tuber diameter (cm), relative growth rate (g g-1 day-1), chlorophyll analysis (mg L-1 ). The results showed that sulfur nutrient modification could strongly predict relative growth rate (R2=0.72) and tuber diameter (R2=0.76), and could moderately predict leaf length (R2=0.59). tillers (R2=0.65), Chlorophyll (R2=0.68), can weakly predict the number of leaves (R2=0.46), thus obtaining an optimum sulfur estimate of 85-86 kg.

PENGARUH PEMBERIAN PUPUK BOKASHI KOTORAN SAPI TERHADAP PERTUMBUHAN DAN HASIL TANAMAN TERUNG (Solanum melongena L.)

Ahmad Redho — 2024-04-22

This study aims to determine the effect of cow dung bokashi fertilizer on the growth and yield of eggplant (Solanum melongena L.). This study used a non-factorial Completely Randomized Design (CRD) consisting of one treatment factor with 6 treatment combinations and 4 replications, so there were 24 treatment combinations. Treatment concentration of bokashi fertilizer consisted of T0 (without bokashi fertilizer), T1 (bokashi fertilizer 1000 g/polybag), T2 (bokashi fertilizer 1200 g/polybag) and T3 (bokashi fertilizer 1400 g/polybag). Parameters observed in this study included plant height (cm), number of branches (branches), flowering age (days), fruiting age (days), number of fruit planted (fruit), weight of fruit planted (g), fruit production per hectare ( tons). The results showed that T3 treatment (bokashi fertilizer 1400 g/polybag) had the best effect on plant height, number of branches, flowering age, fruiting age, number of fruit planted, fruit weight per plant, and fruit production per hectare.

PENGARUH PEMBERIAN PGPR TERHADAP BEBERAPA KOMPONEN HASIL TANAMAN EDAMAME (Glycine max (L) MERRILL.)

Theo Audi Andrean — 2024-04-22

This research aims to determine the effect of PGPR on the production of edamame soybean plants (Glycine max (L.) Merrill). The research method used was a Completely Randomized Design (CRD) with 1 treatment factor, namely R0: Control (without PGPR administration), R1: 5 g PGPR/L water, R2: 7 g PGPR/L water, R3: 9 g PGPR/L water, R4: 11 g PGPR/L water. The research results showed that the PGPR treatment dose of 11 gr/L water gave the highest results for all observed variables such as plant height, flowering age, fresh weight per plant, number of pods planted and plant production.

PENGARUH BERBAGAI DOSIS PUPUK HAYATI MIKORIZA TERHADAP KOMPONEN HASIL DAN HASIL TANAMAN TOMAT (Lycopersicum esculentum Mill.)

Elsiyana Wulandari — 2024-04-22

This research aims to determine the effect of various doses of mycorrhizal biofertilizer on yield component and the result of tomato plants (Lycopersicum esculentum. Mill). This research used a Completely Randomized Design (CRD) with 5 treatments and 6 replications, each replication consisting of 5 polybags of plants. The treatments consisted of : M0 : No mycorrhizal M1 : 1 ton / ha (5g / 10 kg soil) mycorrhizal M2 : 2 ton / ha (10g / 10 kg soil) mycorrhizal M3 : 4 ton / ha (20g / 10 kg soil) mycorrhizal M4 : 6 ton/ha (30g/10 kg soil) mycorrhizal. The results showed that the M4 treatment (6 tons/ha (30 g/10 kg soil) mycorrhizae) had the best effect on plant height, flowering age, fruiting age, wet plant weight, number of fruit each plant, fruit weight each plant and production each hectare.

KOMPOSISI VEGETASI GULMA PADA TANAMAN PISANG DAN JAGUNG LAHAN TEGALAN

Sri Devi Octavia — 2024-04-22

This study aimed to identify and compare the vegetation diversity of weed communities on banana and maize plants on dry land. This study was conducted in banana and corn plantations on dry land located in South OKU Regency, South Sumatra Province from March to April 2021. This study was used weed vegetation analysis using a quadratic method with 3 sample plots for each observation area. The data obtained in the analysis of weed vegetation include: density, dominance, frequency and SDR (summed dominance ratio). The results of the analysis of weed vegetation showed that the dominant weeds in maize plantation were annual weeds in the form of grasses (66.22%). The dominant weeds were Digitaria bicornis, Digitaria sanguilis, and Euphorbia heterophylla. The dominant weeds in banana plantations are annual weeds in the form of broadleaf weeds (100%). The types of weeds with the highest SDR values were Alfalfa invades, Ageratum conyzoides and Commelina benghalensis. Weed communities between maize and banana plants are heterogeneous (0,08%) or weed types that grow are different.
