Astiko W, Ernawati NML, Silawibawa IP.  2021. Concentration of N, P and plant growth in maize-soybean intercropping added mycorrhizae, organic matter and plant nutrients in suboptimal land, North Lombok. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 260-268. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Suboptimal land optimization through intercropping patterns of maize and soybeans using mycorrhizal biological fertilizers and plant nutrition sources has not received much attention. This study aims to determine the concentration of P, N, and plant growth in the intercropping pattern of maize-soybean added mycorrhizal biofertilizer and plant nutrition. The experimental design used was a factorial randomized block design consisting of two treatment factors. The first factor is mycorrhizal biofertilizer (M) which consists of 2 levels: M0 = No mycorrhizal fertilizer and M1 = Using biological fertilizer (1 ton/ha). The second factor is the source of nutrition (U) which consists of 4 levels, namely: U0 = Without the addition of nutrients, U1 = With the addition of 100% dose of inorganic fertilizer only (maize = urea 300 kg/ha and Phonska 200 kg/ha, soybeans = 60 kg/ha Urea and 120 kg/ha Phonska), U2 = With the addition of 100% dose of cattle manure (12 tons/ha), and U3 = With the addition of 50% dose of cattle manure (6 t/ha) + 50% dose of inorganic fertilizer (maize = urea 150 kg/ha and Phonska 100 kg/ha, soybean = 30 kg/ha Urea and 60 kg/ha Phonska. The results showed that 50% dose of cattle manure (6 t/ha) + 50% dose of inorganic fertilizer (maize = urea 150 kg/ha and Phonska 100 kg/ha, soybean = 30 kg/ha Urea and 60 kg/ha Phonska) plus mycorrhizal biofertilizer in maize-soybean intercropping gave the best concentration of N, P and plant growth.

Abstract

Astiko W, Ernawati NML, Silawibawa IP.  2022. Application of several bioameliorant formulations on nutrient concentrations of N, P and growth of maize-soybean intercropping in sandy soils of North Lombok. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 67-77. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Application of bioameliorants with various formulations can increase nutrient concentration and growth of maize-soybean intercropping. The study was aimed to determine the effect of several bioameliorant formulations on increasing nutrient concentrations and the growth of maize-soybean intercropping. The experimental design used was a randomized block design consisting of five treatments of bioameliorant formulation, namely F0: without bioameliorant, F1: with 10% compost + 10% cattle manure + 10% husk charcoal + 70% mycorrhizal biofertilizer, F2: 15% bioameliorant compost+15% cattle manure+ 15% husk charcoal + 55% mycorrhizal biofertilizer, F3: with bioameliorant 20% compost+20% cattle manure+ 20% husk charcoal + 40% mycorrhizal biofertilizer, F4 : with bioameliorant 25% compost+25% cattle manure + 25% husk charcoal + 25% mycorrhizal biological fertilizer. The variables observed in this study were: (1) soil nutrient concentration variables and plant nutrient uptake (N and P) at 42 days after planting, (2) growth variables included: plant height and number of leaves at 14, 28, 42 and 56 dap, and weight of wet and dry root and shoot at 42 dap, and (3) mycorrhizal population variables included: number of spores and percentage of root infection at 42 dap. The results showed that the application of bioameliorants with a formulation of 25% compost + 25% cattle manure + 25% husk charcoal + 25% mycorrhizal biofertilizer in maize-soybean intercropping gave the best concentrations of N, P and plant growth.
