ABSTRACT

A field experiment was carried out during kharif, 2019 on sandy loam soils of wetland farm of S.V. Agricultural College, Tirupati, Acharya N.G. Ranga Agricultural University. The experiment was laid out in randomized block design with factorial concept and replicated thrice. The treatments consisted of four fodder jowar genotypes viz., CSV 32F, CSV 33MF, Pant chari 6 and SSG-59-3 and three nitrogen levels viz., 60, 80 and 100 kg N ha-1. Among the four genotypes evaluated, Pant chari 6 recorded higher green fodder and dry fodder yield, higher crude protein content, crude protein yield, crude fibre yield, total ash content and ash yield. Whereas the genotype SSG-59-3 recorded the higher crude fibre content, while lower crude fibre content was recorded with the genotype Pant chari 6. Application of 100 kg N ha-1 recorded higher green fodder and dry fodder yield, higher crude protein content, crude protein yield, crude fibre yield, total ash content and ash yield, whereas all these were the lowest with application of 60 kg N ha-1. Application of 60 kg N ha-1 recorded the higher crude fiber content.
