Abstract:
A field study was conducted during summer season of 2022-23 at horticultural field of Rama University, Kanpur India to evaluate “Effects of organic manures and chemical fertilizers on the yield and quality parameters of Brinjal (Pusa purple long) under the Agro-climatic conditions of Kanpur”. The experiment was laid out in RBD considering eight treatments replicated thrice. Three different organic manures viz., cowdung, poultry manure and mustard oil cake were used alone and in different combinations and doses with chemical fertilizers. The variety Pusa Purple Long was selected and the combinations of treatment were T₁ (Cowdung); T₂ (Mustard oil cake); T₃ (Poultry manure); T₄(Chemical fertilizer); T₅(50% Poultry manure+50% Cowdung); T6(50% Mustard oil cake +50% Poultry manure); T₇(30% mustard oil cake+ 40% Cowdung+ 30% Poultry manure); T₈(20% cowdung+ 20% Mustard oil cake+ 20% Poultry manure+ 40% chemical fertilizer).All the organic manures, chemical fertilizers and their combinations were applied at the time of transplanting of brinjal in the plot according to the doses that is to be applied in the plot. Among all the treatments, it is noticed that the growth, yield and yield attributing parameters like plant height, numbers of leaves per plant, number of branches per plant, fruit length, fruit diameter, fruit weight, fruit yield per plant, fruit yield per plant, fruit yield per plot, total yield, and quality parameters like total soluble solids, sugar content, reducing sugar and vitamin c content in fruit were found maximm in treatment T₈(20% cowdung+ 20% Mustard oil cake+ 20% Poultry manure+ 40% chemical fertilizer) and the minimum being recorded in T₁(Cowdung). So based on the result it could be concluded that the applications of the organic manures and their combinations with chemical fertilizers (20% cowdung+ 20% Mustard oil cake+ 20% Poultry manure+ 40% chemical fertilizer) favourably a the growth,yield, yield attributing characters and quality parameters of brinjal cv. pusa purple long.
