Soil microbes have suggested to be used as agricultural input. Nitrogen fixing rhizobacteria Azotobacter is responsible to maintain nitrogen nutrition and plant growth whereas Trichoderma enable to reduce soil born plant diseases through antagonistic activity. The objective of this pot experiment was to determine the dosage and application time of carrier- based Azotobacter-Trichoderma inoculant which increase nitrogen availability in soil, as well as growth and yield of chili (Capsicum annuum L.). Chili transplants were grown in low fertility soil mixed with cow manure. Experiment was set up in split plot design which tested four inoculant dosage and three application time. The result showed that effect of biological agent on plant height at three and six weeks after transplanting was not significant. Inoculation of 7,5 g/pot carrier-based Azoto-Tricho at planting time followed by soil dressing with Azotobacter liquid inoculant at 10 day after planting significantly increased NO3 ­- in soil. Carrier-based Azoto-Tricho inoculant irrespective of dosage and application time increased plant yield. The highest yield, 290 g plant-1, was showed by plant treated by 7,5 g po­1t Azoto-Tricho at planting time followed by Azotobacter liquid inoculation. This pot experiment showed that carrier-based Azotobacter-Trichoderma inoculant has potential to be used as biological agent in chili production.

Experiments were conducted to evaluate the performance of red chilli (Capsicum annuum L.) during 2015-16 at the Division of vegetable crops, Indian Institute of Horticulture Research, Hessaraghatta, Bangalore to determine the effect of different fertigation sources and mulching on growth parameters, yield and fertilizer use efficiency (FUE). Fertigation was done both water soluble fertilizers and normal fertilizers with different doses. The results revealed that significantly higher growth and yield parameters viz., plant height (cm), number of branches per plant, leaf area and leaf area index, number of fruits per plant, length of the fruit (cm), girth of the fruit (cm), fruit weight (g) dry fruit yield per plant (g), dry fruit yield per hectare (t) were observed by the treatments viz., application of water soluble fertilizers 100 per cent (Recommended dose of fertilizers) RDF using urea, 19:19:19 and KNO3 through fertigation with mulching, followed by Normal fertilizers 100 per cent RDF using Urea, DAP, MOP through fertigation with mulching. From this investigation it is concluded that water soluble fertilizers as well as normal fertilizers fertigation with mulching ideal for maximum growth and yield of the chilli crop.

Effect of variety and dosage of mycorrhiza on the growth and yield of pepper plants (Capsicum annuum L.) in Andisol. This study aims to determine the effect of varieties and doses of mycorrhiza on the growth and yield of pepper plants on land Andisol and the interaction between these two factors. This research was conducted at the experimental garden in plant physiology laboratory university agricultural Faculty Syiah Kuala start of June 2015 until December 2015. Research using Random Group 4x3 factorial design with three replications, consisting of 36 experimental units consisting of two factors. he first factor is the dose mycorhiza consists of 4 levels of 0, 5, 10 and 15 g / plant. The second factor varieties consisting of Carlos F1, F1 Kiyo, and La Odeng. The results showed that variety significant effect on yield of pepper plants. The best varieties are varieties Kiyo F1 on the generative phase that can be seen from the weight of the fruit crop age parameter 110 HST and 45 HST mycorhiza infection. While the dose of mycorrhizal significant effect on the growth and yield of pepper plants on land Andisol. Dose best mycorrhiza contained in 10g / plants that can be seen in the number of fruit crops as well as the parameters of mycorhiza infection most. Research also shows there is a higher interaction on Carlos F1 varieties with a dose of 15 g / plant in the parameters the number of leaf age 15 HST, At the age of 30 HST rod diameter also gives the best result in two different varieties, namely in Carlos F1 hybrid varieties and local varieties La Odeng on mycorrhizal dose of 15 g / plant and root infection aged 45 HST. La Odeng varieties give the highest number of mycorrhizal infection in mycorrhizal dose of 10 g / plant.
