Abstract:

        Biofertilizer is an alternative source for chemical fertilizer to increase soil health and crop production in sustainable farming. Fish waste solution called Gunapaselam is a product of easily available ingredients and it works as a natural plant growth booster. Gunapaselam in the present study has been evaluated for the efficiency of microorganisms, especially the Ammonifiers, Nitrifiers and Phosphate solubilizer have been isolated and characterized. Gunapaselam as a organic foliar spray is proved to be a fertilizer which is beneficial to the soil and its application promotes the growth of the plants.

Abstract:

        Cabbage (Brassica olearaceae var.capitata) is one of the major vegetables produced and consumed in India. Over the years cabbage is being cultivated more intensively in Theni district of Tamilnadu. This has resulted in higher rates of pest infestation and higher pesticide use. This in turn has contributed to insecticide resistance and human health impact, which has triggered a growing interest in alternative pest management techniques. This investigation was carried out on cabbage grown in red laterite soil at Ambasamuthuram village, Theni district, Tamilnadu, India. The study is aimed to investigate the effect of organic fertilizers and chemical fertilizers and the effect of organic pest repellent (NCBT 01) to control white grubs in cabbage plants as well as to study the economics involved in these practices. The impact of NCBT 01 is unique and effective compared to chemical pesticides.

Abstract:

        There are over 70 different species of Angelfish that live in warm ocean waters around the world. Among them, few species are from fresh waters. Angelfish belong to the Pomacanthus family. The genetic differentiation and phylogenetic relationships among two species of the Pomacanthus family (maculosus and imperator) were investigated by mtDNA sequencing of samples taken from the southern parts of the Persian Gulf. The PCR- sequencing was applied to explore the 1170bp of 12S rRNA and 16S rRNA from the gill tissues of 11 angelfish collected from 3 different parts of the Persian Gulf. Between Pomacanthus imperator and Pomacanthusmaculosus, twenty-two and thirty-one nucleotide differences were found in 12S rRNA and 16S rRNA genes, respectively. According to our phylogenetic trees, all Pomacanthus maculosus specimens taken from three different regions were clustered in one group, whereas the Pomacanthus imperator specimen is phylogenetically separated from the Pomacanthus maculosus specimens.
