ABSTRACT

Tomato are perishable fruit and its growth, yield and quality depends on the management practices. Tomato attributes were studied under controlled condition using manures and pressmud incombination with foliar spray of macro-nutrients and naphthalien acetic acid (NAA) and compared with inorganic soil applied fertilizers. The results of the study showed significantly higher number of branches, chlorophyll content in the treatment recieving inorganic fertilizers, the manures in combination with foliar NPK was comparable. The yield attributes showed that ten fruit weight were greater in the soil applied inorganic fertilizer and it was statistically at par with treatments recieving manure with foliar NPK. Number of fruits per plant were recorded highest in the pots recieving poultry manure either with Foliar NPK or NAA. The yield of tomato was found greater in the treatments recieving soil applied NP, which was statistically similar in the treatment recieving poultry manure with foliar NPK. The treatments in the current study have shown to influence the qualitative parameter of tomato as total soluble solids, while the water content and fruit pH were non significantly changed. Soil properties including soil pH, bulk density, soil organic matter, total nitrogen and extractable phosphorus was significantly altered amongst the treatments. Tomato showed positive response to the organic fertilizers applied along the foliar nutrients in terms of growth, yield and quality. It may be concluded that poultry manure applied along with NAA was comparable with the inorganic fertilizer in improving the growth and yield of tomato, but had the advantage over the inorganic fertilizer in improving the soil properties.
