Abstract:
A field study was conducted during summer season of 2022-23 at horticultural field of rama University, Kanpur India to evaluate “Efficacy of bio-fertilizers and the combinations of macronutrients on the growth, yield and quality of Brinjal (Pusa ankur) under the Agro-climatic conditions of Kanpur”. The experiment was carried out in a Randomized Block Design (RBD) with 5 treatments. Each treatment was replicated four times. The plants were spaced 60*30 cm, i.e. row to row and plant to plant 30×30 respectively. The total area of the each plot was 1.5 *1.30m2. The distance of 1m maintained with in replication. The space of 0.5 meter was kept between the plots. There were 6 rows in each plot and 4 plants were planting in each row. So, there were 24 plants in each plot. 5 sample plants from inner rows were selected for observation and recording of the data. 130 m2 total area of field. Five plants will be selected randomly from each unit plot to record yield contributing characters. The data was taken in 30 days of interval i.e, 30 DAT, 60 DAT and in 90 DAT. There are eight treatment i.e, T1(Recommended dose of NPK(200:150:100)Kg/ha), T2(50% Azotobacter + 50% NPK), T3 (25% Azotobacter + 25% Azospirillium + 50% NPK), T4(25% Azospirillum + 75% NPK), T5(70% Azotobacter + 30% NPK), T6(50% Azospirillum + 50% NPK), T7(50% Azospirillum + Azotobacter 50%), T8(30% Azotobacter+30% Azospirillum +40%NPK). 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, numbers of fruits, fruit weight, fruit yield per plant, total yield were found maximum in treatment T8 (30%Azotobacter+30%Azospirillum +40%NPK) and the minimum being recorded in T1(RDF). So based on the result it could be concluded that the efficacy of bio-fertilizers and the combinations of macronutrients on the growth, yield and quality of Brinjal 30%Azotobacter+30%Azospirillum +40%NPK favourably a the growth, yield, yield attributing characters of brinjal cv. Pusa ankur.
