Influence of nutrients on yield and nutrient uptake of bajra napier hybrid grass


Author(s): C Vennila, VM Sankaran and C Nithya

Abstract: A field experiment was conducted with bajra napier hybrid grass – a perennial fodder crop. Organic and inorganic nutrients were used as nutrient sources during the year 2014-2016. The study was conducted at University Research Farm, Madhavaram, Tamil Nadu Veterinary and Animal Sciences University. The experiment was laid out in Randomized Block Design with twelve treatments viz., F1- FYM 25 t ha-1, F2- FYM 12.5 t ha-1, F3- FYM 25 t ha-1+ 50% RDF (50% NPK as basal + balance through drip), F4- FYM 25 t ha-1+ 100% RDF (50% NPK as basal + balance through drip), F5- FYM 25 t ha-1+ 100% RDF through drip, F6- FYM 12.5 t ha-1+ 50% RDF (50% NPK as basal + balance through drip), F7- FYM 12.5 t ha-1+ 100% RDF (50% NPK as basal + balance through drip), F8- FYM 12.5 t ha-1+ 100% RDF through drip, F9- 50% RDF (50% NPK as basal + balance through drip), F10-100% RDF (50% NPK as basal + balance through drip), F11-100% RDF through drip and F12- Control and replicated thrice. The different combinations with organic and inorganic sources of nutrients were equated to Nitrogen content of the sources of nutrients. Nutrient recommendation for bajra napier hybrid grass was 150:50:40 kg of NPK ha-1. Based on the nitrogen content, the organic and inorganic sources of nutrients, the treatments were formulated. The irrigation was given through drip irrigation. During both the years of experimentation, application of Farmyard Manure at the rate of 25t ha-1 and 100% recommended dose of nutrients applied basally and the remaining through drip resulted in higher yield, however on par with the application of inorganic nutrients through drip alone. The total nitrogen uptake by bajra napier hybrid grass is higher with the application of FYM 25 t ha-1 + 100% recommended dose of fertilizers through drip. Similarly, with respect to phosphorous and potassium uptake, application of 100 % recommended dose of fertilizers through inorganic nutrients along with 25 t of Farm Yard manure to bajra napier hybrid grass resulted in higher uptake.
