UJI PERTUMBUHAN DAN PRODUKSI TIGA VARIETAS TANAMAN BUNCIS (Phaseolus vulgaris L.) DENGAN APLIKASI PUPUK GUANO

2023-02-05T16:17:02+00:00

The examine production three plant variety buncis (Phaseolus vulgaris L.) with using guano fertilizer. The research was conducted between December 2021 until April 2022. The aim of this research was to determinethe most variety superior has growth with using guano fertilizer. Method which used in this research was split random complete (SRC) with 3 variety treatment and 3 guano fertilizer. Variety treatment are V₁ = Lebat variety, V₂ = Perkasa variety, V₃ = Bayu variety. Guano treatment are = 10 ton/ha, = 15 ton/ha, = 20 ton/ha.

The results showed that the variety treatment had a significant effect on plant length treatment at 4 WAP, pod weight per plot and bean plant productivity. Bayu (V3) variety produced the best variety because it produced 46.56 cm long chickpea plants aged 4 WAP, pod weight per plants of 32.51 grams and bean productivity of 2.43 tons/ha. The guano treatment showed a significant effect on the parameters of plant length at 2, 4 and 6 WAP but had no significant effect on the parameters of pod weight and bean productivity. Treatment G3 (20 ton.ha-1) of guano fertilizer gave the best results at 30.38 gram pod weight and 2.27 ton.ha-1 bean production.

2023-02-05T16:44:35+00:00

This study aims to determine the effect of giving POC Multiplant on plant growth and yield of Telang (Clitoria ternatea L.). This research starts from April to May 2021, at Bukit Biru village, Tenggarong Sub District, Kutai Kartanegara District, East Kalimantan Privince. This research was arranged using a Randomized Complete Block Design (RCBD) with POC Multiplant (d) consistend of five levels namely : d₀(without POC Multiplant), d₁(5 cc/L water POC Multiplant), d₂(10 cc/L water POC Multiplant), d₃(15 cc/L water POC Multiplant) and d₄ (20 cc/L water POC Multiplant).

The result of research showed that the POC Multiplant treatment had no significant effect on all parameters, namely plant height, age of first flowering, and also the number of flowers. The highest yield of plants aged 7 days after planting was obtained from treatment d₂ (10 cc/L water POC Multiplant) with an average of 27,60 cm and the lowest was from treatment d₄ (20 cc/L water POC Multiplant) with an average of 24,50 cm. The highest yield of plants aged 14 days after planting was obtained from treatment d₃ (15 cc/L water POC Multiplant) with an average of 63,80 cm and the lowest was from treatment d₀ ( without POC Multiplant) with an average of 57,90 cm. While the highest yield of plants at harvest was obtained from treatment d₁ (5 cc/L water POC Multiplant) with an average of 88,20 cm and the lowest at treatment do (without POC Multiplant) with an average of 75,30 cm. The fastest results of flowering age were obtained from treatment d₁ (5 cc/L water POC Multiplant) with an average of 23,40 days and the longest with treatment d₀ (without POC Multiplant) with an average of 23,90 days. The highest yield of interest was obtained in treatment d₁ (5 cc/L water POC Multiplant) with an average of 12,60 flowers and the lowest in treatment d₂ (10 cc/L water POC Multiplant) and d₄ (20 cc/L water POC Multiplant) with an average of 10,08 flowers.

PENGARUH PEMBERIAN NPK PHONSKA DAN KOTORAN AYAM TERHADAP PERTUMBUHAN DAN HASIL JAGUNG MANIS (Zea mays Saccharata Sturt)

2023-02-05T16:52:15+00:00

This study aimed to determine the effect of NPK phonska fertilizer and chicken manure on the growth and yield of sweet corn (Zea mays Saccharata Sturt). This research started from November 2021 to January 2022, carried out in Jonggon Jaya village, Loa Kulu Sub District, Kutai Kartanegara Regency, East Kalimantan Province.

The study was arranged in a Factorial Randomized Complete Block Design (RCBD) consisting of 2 factors and repeated three times. The first factor was Phonska NPK fertilizer (p), which consisted of four levels, namely p₀ (without treatment), p₁ (150 kg ha^-1), p₂ (300 kg ha^-1), p₃ (450 kg ha^-1). The second factor was the application of chicken manure (s) which consisted of four levels, namely s₀ (without treatment), s₁ (10 t ha^-1), s₂ (20 t ha^-1) and s₃ (30 t ha^-1).

The results showed that Phonska NPK fertilizer had no significant effect on all observation parameters. The highest average yield on cob weight per hectare was p₁ (150 kg ha-1) 14.07 t ha-1. Meanwhile, for the lowest treatment, the average weight of cob weight per hectare was 12.96 t ha-1, namely in treatment p₂ (300 kg ha-1). The results showed that chicken manure had no significant effect on all observation parameters. The highest average yield on cob weight per hectare was s₁ (10 tons ha-1) 14.17 t ha-1. Meanwhile, for the lowest treatment, the average weight of cob weight per hectare was 13.09 t ha-1, namely the s₃ treatment (30 tons ha-1). The results of the interaction between NPK phonska fertilizer and chicken manure had no significant effect on all observation parameters. The highest yield of cob weight per hectare was in the s₂p₁ treatment with an average yield of 14.83 t ha-1 and the lowest yield of cob weight per hectare was in the s₃p₂ treatment with an average yield of 9.52 t ha-1.

This study aims to determine to obtain socio-economic data on bamboo plants related to their use in the community in Tenggarong Seberang District, Kutai Kartanegara Regency, and to formulate a strategy for developing and managing bamboo plants based on local communities in Tenggarong Seberang District, Kutai Kartanegara Regency. This research uses cluster sampling method, while data analysis uses SWOT analysis. Cluster sampling method is carried out by collecting data from clusters that are used randomly according to needs taken from certain strata or groups, namely Farmers, Community, Traders, Community Leaders, and Dinas Lingkungan Hidup dan Kehutanan Kutai Kartanegara Regency. The results of the study show a socio-economic description of bamboo plants from the side of their use, namely several types of bamboo that have been found and identified in Tenggarong Seberang District including black bamboo, yellow bamboo, butar bamboo, china bamboo, petung bamboo and thorn bamboo. The main occupations of farmers in Tenggarong Seberang District are field farmers and sugar palm farmers. The selling price of bamboo at the farmer level is Rp. 500.00 for one stem. Meanwhile, the selling price of one ironwood stick for a plant pillar is Rp. 2,000.00. Then the strategy for developing and managing bamboo plants in Tenggarong Seberang District is appropriate for bamboo plant farmers, namely providing and setting boundaries between company forest areas and community forests and granting business permits and guarantees from the government.
