Evaluation of the effect of Nanobiomic fertilizer on yield and some traits of Hibiscus sabdariffa in intercropping with Vigna unguiculata

Today, the growing trend of degradation of water, soil and environmental resources due to the indiscriminate use of chemicals in agriculture and common methods of food production, has attracted the attention and encouragement of agricultural researchers to sustainable agriculture. Mixed cultivation is of particular importance for the variety of crops, their benefits, and the increase in profits per unit area and time. The aim of this study was to investigate the synergistic effect of sour tea mixed culture as a medicinal plant and compatible with the conditions of the region with cowpea and the effect of nanobiotic fertilizer in mixed culture.To investigate the effect of Nanobiomic fertilizer application on quantitative and qualitative characteristics of sour tea in mixed cultivation with blueberry beans, an experiment in the form of split plots in a randomized complete block design with three replications, in Zabol University research farm located in the new site. It was implemented in 2015-2016. Factors studied include nanobiomic biofertilizer as the main factor in two levels of use and non-use of biofertilizer and different levels of intercropping in five levels including pure Hibiscus sabdariffa, pure Vigna unguiculata, 50% Hibiscus sabdariffa + 50% Vigna unguiculata, 75% Hibiscus sabdariffa +25% of Vigna unguiculata and 25% of Hibiscus sabdariffa + 75% of Vigna unguiculata were a by-product. Nanobiomic biofertilizer was applied in three stages (three-leaf, stem and before flowering) and in each stage at the rate of one liter per hectare.Comparison of the mean of interactions showed that the highest amount of chlorophyll a was obtained from nanobium application treatment in 75% Hibiscus sabdariffa + 25% Vigna unguiculata. Also, the highest total chlorophyll was obtained in 75% Hibiscus sabdariffa + 25% Vigna unguiculata. Vigna unguiculata was obtained. Land parity ratio in mixed cropping systems was higher than one, which indicates the advantage of mixed crops compared to pure crops. Intercropping of 50% Hibiscus sabdariffa + 50% Vigna unguiculata had the highest land parity ratio. The highest economic yield of Hibiscus sabdariffa was obtained from nanobiomic application treatment. Comparison of the means of effect of different intercropping systems showed that the highest amount of economic yield (11125.6 kg / ha) was obtained from the pure culture of Hibiscus sabdariffa.Based on the results, the highest biological yield and economic yield of sour tea were obtained from the application of nanobiomics in the conditions of pure planting system of sour tea. In general, it can be said that a mixed culture of 50% sour tea + 50% cowpea with suitable economic yield is suitable for cultivation in the region.
