Effect of N & P management with and without bio organics on growth and yield parameters of kharif sorghum under South Gujarat conditions

Abstract

A field experiment was conducted during 2016-17, 2017-18 and 2018-19 to study the Effect of N & P management with and without bio organics on growth and yield parameters of kharif sorghum under South Gujarat conditions. There were fifteen treatments comprising of three fertilizer levels of N & P [60+30kg/ha (F1), 80+40 kg/ha (F2) and 100+50 kg/ha (F3)] along with five bio organics levels [Control (B1), Azospirillium @ 3l/ha (B2), AM @ 250 g/ha(B3), Azospirillium & AM(B4) and NAUROJI Novel organic liquid fertilizer (1%) at 45 and 60 DAS (B5). The experiment was laid out in factorial RBD with three replications. The type of soil was medium black and no sever pest and disease incidence were observed on sorghum during the experiment. The plant height (187.00 cm) was recorded significantly higher under the treatment having application of F3 (100+50 NP kg/ha) and also significantly higher under the treatment having application of B4 (Azospirillium & AM). Interaction effect FxB was found significant during all the individual years as well as in pooled data. F3B2 interaction recorded significantly higher plant height (192.29 cm) in pooled data which was found statistically at par with F3B5 and F1B4. The length of ear head was found significantly higher (21.53 cm) with the treatment F3 (100+50 NP kg/ha) which was found statistically at par with F2 (80+40 NP kg/ha) in pooled data.
