Effect of Use Probiotics and Organic Fertilizer on Yield of Peanut on Tra Vinh Province, Vietnam

This study was to evaluate the effects, determine the appropriate, and assess the profitability of using locally produced organic foliar fertilizers on peanut production. The experiment was installed in CauNgang andTra Cu with two variety MD7, L14. Seven fertilizer treatments were designed.The treatments consisted of the application of T1:(Trichoderma sp + Bordeaux 1% + Probiotics 3M; T2: (organic fertilizer =10 ton/ha);T 3: (Trichoderma sp + Bordeaux 1% + Probiotics 3M + chemical fertilizers(35N-60P-60K + 150kg Ca + 40kg Mg) + organic fertilizer 100%) T4: (Trichoderma sp + Bordeaux 1% + Probiotics 3M + chemical fertilizers(35N-60P-60K + 150kg Ca + 40kg Mg) + organic fertilizer 75% ;T 5( Trichoderma sp + Bordeaux 1% + Probiotics 3M + chemical fertilizers + organic fertilizer50%) ;T6: chemical fertilizers(35N-60P-60K + 150kg Ca + 40kg Mg)+(Trichoderma sp + Bordeaux 1% + Probiotics 3M)and T7 control and treatment of farmers: (120 N-60 P-60 K + 200 Ca kg/ha). The experimental design adopted consisted of randomized complete blocks with three replications. Results showed that peanut plants flowered early when applied with T3 (Trichodermasp + Bordeaux 1% + CPVS 3M) + chemical fertilizer + 100% organic fertilizer) significantly increase plant height, number of branches/ plant, ability to absorb N. P. K. 100 seeds,weight of pods( g/ plant) and seeds of plant. The increase/decrease in fertilizer intake had a significant and statistically significant effect (p ≤ 0.05) on peanut yield and quality in both treatments areas, with the exception of 100 grains. If only organic fertilizer is not combined with microbiological preparations, the manure of black spots and brown spots is higher than the experimental in combination with the treatment fertilizer combined with the balanced amount of fertilizer in the T5 treatments(Trichoderma sp + Bordeaux 1% + Probiotics 3M + chemical fertilizers + organic fertilizer50%).
