Integrated use of organic and inorganic fertilizers on the growth and yield of Boro rice (cv. BRRI dhan 29)

Abstract

A field experiment was conducted to evaluate the integrated effect of cow dung, poultry manure and water hyacinth with chemical fertilizers on the growth and yield of Boro rice (cv. BRRI dhan29). The effect of different levels of organic fertilizers in combination with recommended doses of inorganic fertilizers were tested over growth parameters and yield of rice.Among the yield contributing characters studied plant height, effective tillers hill-1 , panicle length and filled grains panicle-1 were varied significantly by the different treatments. Most of the yield contributing characters influenced positively in treatment having quarter doses of cow dung, poultry manure and water hyacinth over recommended dose. The highest grain yield (5.58 t/ha)and straw yield (7.28 t/ha) were observed in that same treatmentT6 (1/3 Cow dung + 1/3 Poultry Manure + 1/3 water hyacinth + Fertilizers) over other treatments. Thus, the application of cow dung, poultry manure and water hyacinth with chemical fertilizers had significant and positive effect on N, P, K and S contents of rice.

Integrated nutrient management practices on dry matter production, yield and NPK content of transplanted rice

“…Grain and straw yield Significantly higher grain and straw yield of paddy were found in soil treated with inorganic and organic sources of nitrogen and their combinations over untreated control (Table 2). Similar reports on higher yield due to application of inorganic and organic N sources applied either singly or in (2018) [8,9,23,12] . Pooled mean values showed that soil treated with 75% RDN from urea + 25% RDN from FYM + 10 tonnes Azolla ha -1 (T 10 ) yielded significantly higher grain and straw yield followed by 50% RDN from urea + 50% RDN from FYM + 10 tonnes Azolla ha -1 (T 11 ) showing parity with T 8 and T 5 on grain yield.…”

Modulation of Yield and Yield Attributes of Transplanted Aman Rice through Organic and Inorganic Fertilization in Terrace Soil

“…Chemical fertilizers applied at various doses have an enormous effect on plant height [19]. Application of organic manure combined with chemical fertilizers performed better in boosting plant height than single treatment [20]. As compared to sole application of the recommended fertilizer dose, the combined application of fertilizers and manure enhanced plant height is similar to our findings [3].…”

“…The lowest TSW was found in case of rice straw treated plot which was 20.73 g. While application of different N doses also positively influences the TSW of Binadhan-7. The highest TSW was found in the plot received 150 kg ha -1 N which was 22.83 g followed by 100 kg ha -1 N which was 22.05 g and the minimum TSW was recorded in the plot received no N fertilizer which was 22.05 g. A significant effect of organic and inorganic fertilizer on 1000-grain weight was concluded by scientist [20]. A substantial change in TSW of rice as exaggerated by variations in fertilizer packages [22].…”

“…Combined application of OM and N fertilizer have significant effects on T. aman rice in terms of plant height, tillers hill -1 , effective tillers hill -1 , panicle length, grains panicle -1 , filled grains panicle -1 , unfilled grains panicle -1 , TSW, grains yield, straw yield, biological yield, and HI (Table II In case of plant height, significantly maximum height was found in the poultry manure along with N150 dose which was 98.50 cm and the lowest height was found in the treatment combination of rice husk biochar with no N fertilizer (N0) which was 78.5 cm. Poultry manure in combination with 150 kg ha -1 N dose significantly rendered the maximum number of tillers (20) and effective tillers (18) per hill, panicle length (27.5 cm), grains (145.0), filled grains (138.0) per panicle as well as 1000 grains weight (23.65 g), grain yield (5.41 t ha -1 ), straw yield (8.97 t ha -1 ) and biological yield (14.34 t ha -1 ) of T. aman rice followed by PMN100 combination. The lowest number of tillers (8.5) and effective tillers (7.50) per hill and grain yield (4.40 t ha -1 ) were recorded in RHBN0 treated plot.…”

“…Grains per panicle increase in rice through the utilization of PM [31]. Sohela et al noticed the substantial impacts on the number of grains in each panicle due to addition of organic and inorganic source of nutrients [20]. Balanced nutrition supplied by integrated means renders maximum vegetative growth of plants which helps to functions the photosynthetic system properly resulting the best grain filling in rice.…”
