| dc.description.abstract | A field experiment “Effect of organic and inorganic sources of nutrition on sorghum + pearl millet fodder production, associated weed flora and soil properties” was conducted at Research Farm of Fodder Section, CSKHPKV, Palampur during Kharif 2019. Soil of the experimental field was acidic in reaction, high in organic carbon, low to medium in available nitrogen, medium in available phosphorus and medium in available potassium. The experiment was laid out in randomized block design with three replications, consisting of nine treatments having eight combinations of two nitrogen levels (no nitrogen and 50 per cent of recommended nitrogen), two FYM levels (10 and 15 t/ha) and two levels of Jeevamrit concentration (5 and 10 per cent), plus one treatment of recommended dose of NPK (120, 60, 40 kg/ha) through inorganic sources. Treatments comprised of integrated nutrient management (50 per cent recommended N + FYM + Jeevamrit) and recommended NPK behaving alike resulted in better crop growth (emergence count, plant height, shoot number, leaf stem ratio, dry matter accumulation), fodder yields (green and dry), crude protein content, crude protein yield and lower weed population and weed dry matter accumulation compared to organically managed systems with variable levels and concentration of FYM and Jeevamrit, respectively. The uptake of N, P and K by crops was significantly higher with 50 per cent recommended N + 15 t/ha FYM + 10 per cent Jeevamrit. Application of recommended NPK proved most profitable with highest net return (₹ 59,018/ha) and benefit-cost ratio (2.75). Treatments with integrated use of 50 per cent recommended N + FYM and Jeevamrit increased available soil nitrogen, phosphorus and potassium over initial values and increase was highest with recommended NPK. The soil organic carbon and microbial biomass carbon were highest with 50 per cent recommended N +15 t/ha FYM + 10 per cent Jeevamrit. | en_US |
