Abstract:
The experiment was undertaken during kharif 2022 at the Research Farm of Fodder Section, CSK Himachal Pradesh Krishi Vishwavidyalaya, Palampur (H.P.) with the objective to study the effect of nano DAP on growth indices and yield of rice (Oryza sativa L.) in mid-hills of Himachal Pradesh. The experiment consisted of twelve treatments and three replications with randomized block design (RBD). The treatment consisted of different levels of conventional nitrogen and phosphatic fertilizer with or without seedling dip @ 5 ml/l water and sprays of Nano DAP (@ 2 ml/l and 4 ml/l). The fertilizer dose for transplanted rice was 90:40:40 kg/ha with Hybrid PAC 807+ as variety. The soil of the experimental site was silty clay loam in texture, acidic in reaction, low in available nitrogen and medium in available phosphorus and available potassium content. The results obtained from the present investigation clearly indicated the significant influence of different NP level treatments (75 or 50% NP) with or without Nano DAP application on the growth and yield of rice. Application of treatment, T8 - 75% NP along with seedlings treated with nano – DAP and two foliar sprays of nano – DAP @ 0.4% at 30 days after transplanting (DAT) and 60 DAT gave significantly higher values of plant height (60 DAT, 90 DAT and at harvest), CGR, RGR as well as grain yield, straw yield and harvest index though it was at par with the application of 100% recommended NPK (T2) as well as all other treatments where either 50 or 75% recommended NP was applied along with seedling treatment and foliar application of nano – DAP.
