The experiment was conducted to evaluate the efficacy of Trichoderma-enriched biofertilizer(BioF/compost)on antioxidants and minerals in ripe tomatoes and soil health improvements in terms of nutrient availability and microbial populations.The study was comprised of six treatments:control(zero input);recommended doses of NPK(135.5,45.6 and 22.9 kg ha~(–1),respectively);100%BioF/compost;75%BioF/compost+25%N;50%BioF/compost+50%N;and 25%BioF/compost+75%N.The recommended doses of P and K were used in the last three treatments.It was found that the application of 100%BioF/compost enhanced plant growth,leaf greenness,and produced 12.9%higher yield compared to the recommended doses of NPK and other treatments.Mineral contents(P,K,Ca,Mg,Cu,Fe,Mn and Zn)in tomato roots,shoots and fruits and antioxidant compounds,i.e.,ascorbic acid,β-carotine,and lycopene were increased significantly in fruits fertilized with100%BioF/compost.The high efficiency of Trichoderma compost might be the result of its potential of nutrient solubilization and harboring soil microorganisms.Collectively,BioF/compost increased soil fertility and favored growth of microbes in the rhizosphere which ultimately contributed to higher yield,antioxidant,and mineral concentrations in tomatoes.Thus,Trichoderma-enriched biofertilizer may reduce application of chemical fertilizers and therefore,can be considered as a noble practice in sustainable agriculture.
The experiment was conducted to evaluate the efficacy of Trichoderma-enriched biofertilizer (BioF / compost) on antioxidants and minerals in ripe tomatoes and soil health improvements in terms of nutrient availability and microbial populations. The study was comprised of six treatments: control (zero input ); recommended doses of NPK (135.5, 45.6 and 22.9 kg ha -1, respectively); 100% BioF / compost; 75% BioF / compost + 25% N; 25% BioF / compost + 75% N. The recommended doses of P and K were used in the last three treatments. It was found that the application of 100% BioF / compost enhanced plant growth, leaf greenness, and produced 12.9% higher yield (P, K, Ca, Mg, Cu, Fe, Mn and Zn) in tomato roots, shoots and fruits and antioxidant compounds, ie, ascorbic acid, β-carotine, and lycopene were significantly significantly in fruits fertilized with 100% BioF / compost. high rate of Trichoderma compost might be the result of it s potential of nutrient solubilization and harboring soil microorganisms. Collectively, BioF / compost increased soil fertility and favored growth of microbes in the rhizosphere which have contributed to higher yield, antioxidant, and mineral concentrations in tomatoes. Thus, Trichoderma-enriched biofertilizer may reduce application of chemical fertilizers and therefore, can be considered as a noble practice in sustainable agriculture.
