Oryza sativa - Opis:
- A field experiment was carried out with two varieties of rice (BR 11 and BRRI dhan 31) during Transplanted Aman season of 2018 in K. bearing deep grey terrace soil of Madhupur tract (AEZ 28) under Bangladesh Rice Research Institute (BRRI), Joydebpur. Gazipur. The objective of the study was to know the effect of NPKSZn on the growth and yield of BR 11 and BRRI dhan 31. There were ten treatment combinations with three replications. The treatments were complete (+NPKSZn), reverse complete (-NPKSZn), +N (+PKSZn), -N (+PKSZn), +P (+NKSZn), -P (+NKSZn), +K (+NPSZn) and -K (+NPSZn). The parameters under study were dry matter production, contents and uptake of N, P, K, S and Zn at active and maximum tillering stages, panicle number m’ and grain yield in both the varieties. All the parameters were positively influenced by the treatments under study. Growth and yield of both the varieties were largely affected by the missing nutrient treatment. The highest performance was found with the complete and reverse control treatments whereas the lowest was found with missing element treatments and of course, with control. BR 11 was found to be a better variety than BRRI dhan 31 in respect of yield and yield contributing characters under the treatments. It was also observed that recently fertilized reverse control plot behaved statistically the same as the long term fertilized complete treatment plot. Yield of rice was positively related to K uptake in both the varieties.
