Abstract:
The field experiment was carried out during the Kharif season of 2002-03 at Experimental Farm of G.P.B. of A.N.D.U.A.T., Kumarganj, Ayodhya, (U. P.) with objective to study the effect of different nitrogen levels and bio - fertilizers on growth, yield and quality of fodder sorghum (Sorghum bicolor L.). The soil of the experimental field was silty loam in texture with low, medium and high in N, P and K respectively. The experimental site is situated in a subtropical zone in indo gangetic planes. The experiment was laid out in Randomized Block Design (Factorial). The field experiment has six Nitrogen levels (0, 20, 40, 60, 80 and 100 kg/ha) and three different Biofertilizers (control, Azotobacter and Azospirillum). Sorghum was sown on 25th June 2002 with 18 treatment combinations and 3 replications. Based on research investigation, it was found that increasing levels of Nitrogen and different Bio-fertilizers had a significant effect on growth, yield and quality of fodder sorghum. The crop was harvested on 27th Oct. 2002. The result indicated that the Nitrogen level (N - 100 kg/ha) was registered significantly superior in terms of plant height, (332.90 cm), dry matter (67.52 q/ha.) and green fodder (428.29 q/ha.) respectively over rest of the treatments, while protein content was at par with Nitrogen level (N - 80 kg/ha.). Among different Bio-fertilizers Azospirillum and Azotobacter recorded significantly higher plant height (297.62 and 295.93 cm), dry matter (52.66 and 52.73 q/ha.), green fodder (329.64 and 329.12 q/ha.) and protein content (8.19 and 8.30) over without inoculated treatment, while both the treatments (Azospirillum and Azotobacter) were at par to each other. Highest gross return (Rs 17875.20/ha), net return (Rs 11047.25/ha.) and benefit: cost ratio (1.61) was obtained with the application of Nitrogen level (N - 100 kg/ha) along with Bio-fertilizer (Azospirillum) respectively.
