INFLUENCE OF INTEGRATED USE OF MANURES AND FERTILIZER ON THE GROWTH AND YIELD OF HYBRID DHAN HIRA 2

Abstract

A field experiment was conducted to assess the eThel of integrated ntitrietTh management on the grosiIi and yield of hybrid dhan I lira 2 at the research filnil of Sher-e-l3angla Agricultural University. Dhaka-1 207 in Boro season 2011-12. Growth and yield contributing characters of h brid dhan I lira 2 were signiticantly affected by di lThrent treatments cT 1 : No chemical lrtilizer and 110 manures (Control). 12: 120 kg N/ha from urea. 13: 90 kg N/ha lioni urea— 30 kg N/ha from vermkompost (VC). T4: 90 kg N/ha from urea+ 30 kg N/ha from pressmud. T5: 60 kg N/ha from urea± 60 kg N/ha Ironi vernileompost VC). T6: 60 kg N.!ha 1mm urea+ 60 kg N/ha from pressnitid. T: 30 kit Ntha tr011) urea -90 kg N/ha from vermicompost (VC). T8 : 30 kg N/ha from urea- 90 kg N/ha from pressmud. T.;: 120 kg N/ha horn verniieompost (VC) and T10 : 120 kg N/ha from pressmu(l) except one. non-eliective tillers per 11111, which was insignificant to di IThrent treatments. The highest plant height (95.00). number of tillers per lu 11(16.67). effective tillers per hill (15.33). panicie length (25.64). number of grain per panicle (146.0). number of tilled grain per panicle (142.3) and Weight of 1000 grains (33.33) were found front I treatment. On the oilier hand the lowest values of these parameters were obtained from F, treatment receiving no manure and chew ical lbrti I izer. The Ii ighesi. number ut un ill ted grain per panicle (8.00) Ibund from I. N and the lowest (3.67) from l ircauhient. Yield parameters ol hybrid dhan Ilira 2 were significantly atThcted bN diffeitni treatments. The highest raw grain yield (9.56 1/ha). raw straw yield (14.67 i/ha), dry grain yield (8.78 i/ha) and dry straw yield (7.62 i/ha) Were louitd from 1'; treatment. On the oilier hand the lowest values of these parameters were obtained li-am T1 treatment. Nutrient concentration in grain and straw of hybrid dhan I hra 2 was signilieantly affected by diilèrent treatments. ihe highest concentrations of N (I .092%). P (0.297%). K (0.374%) in grain and the highest K (1.213%) and S (0.091 %) in straw were recorded in I treatment, the highest concenirations of S (0.1 24%) in grain and the highest concentrations of N (0.742(Nt,) and P (0. I $2%) in straw were recorded from 1' treatment and in all cases the lowest values ere observed in li (control) treatment. Nutrient uptake (k-Ino by grain and straw of hybrid dhan 1-lira 2 was significantly affected h' different treatments. The highest amount of N (93.8 I ). P (26.07). K (32.82) and S (10.79) uptake by grain and the highest amount of N (55.70). P (13.79). K (92.43) and S (6.91) uptake by straw were tiittnd in the 1; treatment and in all cases the lowest values were observed in I I treatment. The organic matter and levels of N. P. K and S of post-harvest soil were significantly affected In dilThrent treatments whether p11 of post-harvest soil was insignificant. The highest organic matter (I .67%). total N (0.070%). available P Cl I .71 ppm) & S (11.46 ppm) and K (0. 166 meq/1 00 g soil) were recorded from L. l" 3. 12. T. treatments respectively and in all cases the lowest values were observed in i I treatment.
