Title : Effect of cutting and splitting of nitrogen doses on yield, quality and economics of fodder oat in Indo-Gangetic plains of India
Abstract:
Field study was conducted at Instructional Dairy Farm, Nagla, G. B. Pant University of Agriculture and Technology, Pantnagar from 2019-20 to 2021-22 during Rabi season (October-November to March-April) to assess the ‘Effect of cutting and splitting of nitrogen doses on yield, quality and economics of fodder oat in Indo-Gangetic plains of India’. The experimental site was located in the Tarai region of Shivalik range of Himalayas in between latitude of 29° N to longitude of 79.3° E and at an altitude of 243.84 meter above the mean sea level. The soil was slightly silty clay loam in texture with granular structure having soil pH 6.70, EC 0.25 dS/m, organic carbon 0.75%, available nitrogen, phosphorus and potassium, 200.4. 19.0 and 226.3 kg/ha, respectively. The experiments results indicated that oat varieties UPO-06-1 and UPO-212 gave the highest green and dry fodder yield, respectively, however both were significantly similar. The crude protein production was found higher in UPO-212 but remained significantly equal to UPO-06-1. The gross and net returns were recorded significantly higher in UPO-06-1 but the B:C ratio was significantly higher in UPO-212. Similarly the plant height, number of tillers/m row length, green and dry fodder yield and its respective productivity, crude protein content, crude protein production and economics were found higher at two cuts with 50% N application as basal followed by 50% N at 1st cut that was significantly similar with two cuts with 60% N application as basal followed by top dressing of 40% N at 1st cut. It is therefore concluded that oat variety UPO-06-1 or UPO-212 could be harvested twice with application of 50% N as basal followed by top dressing of 50% N at 1st cut for higher fodder and crude protein yield and net return in Indo-Gangetic plains of India.
