Impact of tillage intensity, fertilizer and manuring on yield contributing characters of rice.
Journal Title: Scientia Agriculturae - Year 2015, Vol 10, Issue 1
Abstract
A field experiment was carried out at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during aman season of 2013, to study the impact of tillage intensity, fertilizer and manuring on soil physical properties, water conservation and yield of rice. The experiment was laid out in a split-plot design with three tillage treatments in main plot and four fertilizer and manuring treatments in sub plots and replicated thrice. The unit plot size was 4 m x 2.5 m. The maximum bulk density of 1.61 g cm-3 and minimum bulk density of 0.87 g cm-3 were observed in P1 at 10-20 cm depth and by P3 at 0-10 cm soil depth. The highest soil moisture content of 51.68% was found under P3 at 0-10 cm depth and the lowest value of 37.91% in P1 at 10-20 cm depth. The highest air-filled porosity of 12.16% was found under P2 at 0-10 cm soil depth. Considering tillage treatment, the highest number of tillers hill-1 (11.80), number of grains panicle-1 (106.97), 1000-grain weight (21.58 g) and grain yield (4.40 t ha-1) were observed in P3 treatment. The lowest straw yield (4.18 t ha-1) and grain yield (3.64 t ha-1)was found in P2 treatment. The soils were manipulated with different tillage operations thereby reduced compactness of soil and increased the number of pore spaces, which decreased soil bulk density. As a result, yield of rice increased.
