Effects of Planting Density and Weeding Frequency on the Corn Growth and  Yield in Intercropping System with Peanut

The research aimed to determine the optimal population ratio at each frequency of weeding for the growth and yield of maize. It was carried out from February to May 2020 in the field. There are 2 treatment factors tested arranged in a splite plot design, which was repeated 3 times using a completely randomized block design (CRBD). The first factor is the frequency of weeding as the main plot (Main Plot) consisting of no weeding, 1 x weeding (21 DAS), 2 x weeding (21 DAS and 42 DAS). The second factor is the ratio of the population as sub-plots, consisting of 100% corn + 0% peanuts, 80% corn + 20% peanuts, 60% corn + 40% peanuts, 40 % corn + 60% peanuts, 20% corn + 80% peanuts. The results showed that the growth and yield of maize in the intercropping system with peanuts gave the same response to the population ratio at all weeding frequencies. The planting density of 40% maize + 60% peanuts produced the highest response on the variables of stem diameter (24.675 mm), plant fresh weight (667.51 grams) and biomass weight (79.924 grams). While the highest response to weeding frequency was 2 times (21 DAS and 42 DAS) only on plant fresh weight (588.08 grams).

ABSTRAKPenelitian ini mempunyai tujuan untuk mengetahui durasi perendaman bibit dengan auxin alami dan dosis pupuk NPK yang tepat pada pertumbuhan dan hasil tanaman bawang merah (Allium ascalonicum L). Dalam budidaya bawang merah sering dijumpai pertumbuhan benih yang lambat disebabkan karena faktor dalam bibit (endogenous factor) yang merugikan karena akan berdampak pada serangan penyakit busuk umbi. Maka mempercepat munculnya tunas dengan perlakuan pemberian auxin dan pemberian pupuk NPK ini diharapkan akan diperoleh bibit yang segera tumbuh supaya dapat berproduksi dalam keadaan sehat. Pada penelitian ini akan dikaji bagaimana mempercepat pertumbuhan bibit bawang merah dengan perendaman cepat dalam auxin alami yang diinteraksikan dengan pemberian pupuk NPK. Penelitian disusun dalam RAK faktorial dengan 2 faktor sebanyak 3 x ulangan. Faktor 1 adalah perlakuan lama perendaman bibit bawang merah (D), yang terdiri dari D0 = tanpa perendaman , D1= perendaman 0,5 jam, D2 = perendaman 1 jam, D3= perendaman 1,5 jam, D4 = perendaman 2 jam. Sedangkan faktor kedua adalah pemberian pupuk NPK, P1= 100 kg/ha, P2= 200 kg/ha, P3= 300 kg/ha. Variabel yang diamati adalah tinggi tanaman, jumlah batang/rumpun, bobot segar bawang merah/rumpun, jumlah umbi bawang merah/rumpun. Data dianalisis dengan menggunakan Anova dan uji DMRT 5%. Hasil Penelitian didapatkan bahwa ada pengaruh interaksi nyata antara perlakuan D (lama perendaman) dan P (dosis pupuk NPK) pada variabel tinggi tanaman, jumlah batang/rumpun, bobot segar bawang merah/rumpun dan jumlah umbi/rumpun. Perlakuan terbaik adalah D4P3 yaitu perendaman bibit bawang merah selama 2 jam dengan pemupukan NPK anorganik 300 kg/ha. ABSTRACTThe aims of the study was to determine the duration of bulb dipping with natural auxin on the growth and yield of shallot (Allium ascalonicum L). In shallot cultivation, it is found that the slow growth of bulb is caused by the factors in the bulbs (endogenous factors) because it will impact on bulb rot disease. Then accelerating the emergence of shoots with the treatment of auxin and NPK fertilizer, it is hoped that the bulbs will grow well so that they will be harvested in a healthy condition. In this research, we will study how to accelerate the growth of shallot bulbs with rapid immersion in natural auxin which is interacted with NPK fertilizer. The research was arranged in a factorial randomized block design with 2 factors and repeated 3 times, where the first factor was the treatment was the length of dipping the shallot seeds. (D). consisting of D0 = without dipping, D1 = dipping 0.5 hours, D2 = dipping 1 hour, D3 = dipping 1.5 hours, D4 = dipping 2 hours. While the second factor is the provision of . NPK . fertilizer, P1 = 100 kg / ha, P2 = 200 kg / ha, P3 = 300 kg.ha. The variables observed were plant height, number of clumps / plant, fresh weight of shallots / plant, number of shallot bulbs / plant. Observation data were analyzed by ANOVA and 5% DMRT test. The results showed that there was a significant interaction effect between D and P treatment on the variable plant height, number of clumps/plant, fresh weight of shallots / plants and number of tubers / plants. The best treatment is D4P3, which is soaking shallot seeds for 2 hours with 300 kg / ha of inorganic NPK fertilization.
