Soil Test Based Inorganic Fertilizer and Integrated Plant Nutrition System for Rice (&lt;i&gt;Oryza sativa&lt;/i&gt; L.) Cultivation in Inceptisols of Bangladesh

Scarce findings on phosphorus (P) uptake and its utilization under increased zinc (Zn) levels in organic fertilizers amended soil led to conducting research. The aim of the study was to determine the effect of increasing the application of zinc (200, 400, and 600 mg·kg−1 of soil) together with different organic fertilizers (bovine manure, chicken manure, and spent mushroom substrate) on the content and uptake of phosphorus by cocksfoot and the phosphorus use efficiency from organic fertilizers. The application of different amounts of zinc did not affect phosphorus content in the grass, but it significantly influenced its accumulation (p < 0.05). The most phosphorus uptake was accumulated by plants following zinc application at 200 mg·kg−1 of soil and the least following application of 600 mg·kg−1 of soil. The phosphorus use efficiency from organic fertilizers was increased by zinc application of 400 mg·kg−1 of soil and reduced by 600 mg·kg−1 of soil. Organic fertilizers did not significantly affect the phosphorus content in the grass but did increase its uptake. The highest phosphorus use efficiency was obtained for bovine manure. The study showed no antagonistic relationships between zinc and phosphorus, but increasing zinc application affected the coefficient of phosphorus utilization from organic fertilizers.

“…Rational fertilization and management of soil fertility could be one of the most important measures to improve rice productivity and soil quality because inadequacy of five nutrient elements (NPKSZn) in many paddy soils of Bangladesh is responsible for reaping high yields [6] [7]. In general, missing of one nutrient element from complete fertilization reduced grain yield of rice, but it was reversible when missing nutrients were added [8] [9] [10].…”

Background and objective: Long-term fertility study is one of the important factors to monitor changes in yield because of different nutrient management options and cropping systems involved in Asian regions. Many short-term and long-term fertilizer trials were conducted for intensive irrigated rice cropping patterns mostly to provide fertilizer rate, but did not considered sustainable soil management for soil health. The objective of the present study was to examine the effect of missing nutrient elements for a long time on rice yield, photosynthetic rate and residual soil fertility. Materials and Methods: The experiment was initiated on a permanent layout at the Bangladesh Rice Research Institute (BRRI) farm, Gazipur during 2000 to 2008 in wet season. Seven treatments in randomized complete block design with four replications were imposed. Grain yield was determined at physiological maturity from three 5 m 2 areas within each plot followed by bagging and threshing. Photosynthetic was measure by Li Cor 6400 (USA) machine during study period. Soil sample was analyzed for following standard methods. Results: It was found that grain yield was in decreasing trends for the missing elements that were similar with BR 11 and BRRI dhan 31. On an average, grain yield reductions were 11.6, 7.0, 10.6, 1.1 and 3.4 percent for −N, −P, −K, −S and −Zn, than complete fertilizer treatment (NPKSZn) respectively. Under no fertilization, the ability of soil was to produce 2.9 t•ha −1 of BR11 and 3.1 t•ha −1 of BRRI dhan 31 respectively. Photosynthetic rate of rice plant was always higher in complete fertilizer treatment (NPKSZn) than missing of any nutrient element. The decrease in photosynthetic rate was more pronounced with N missing than others for both the rice varieties. Conclusion: It is concluded that balance chemical fertilizers (NPKSZn) are to be used for sustained and/or increased rice production and to maintain soil fertility.

“…In Bangladesh, farmers generally use chemical fertilizers with little or no use of organic manures to meet the rice nutrient requirement, which results in degraded soil health and decreased rice yield (Sarkar et al, 2016). Farmers could not use sufficient organic manures as they are required in bulk amount and are less available.…”

A field experiment was conducted at two locations (Gazipur and Satkhira) during the Boro (dry) season in 2020 to study the performance of Nitrobenzene on the growth and yield of rice. Four different concentrations of Nitrobenzene (2.0 mL L-1, 2.5 mL L-1, 3.0 mL L-1 and 3.5 mL L-1) as foliar spray with recommended chemical fertilizer (RF) were tested on BRRI dhan89 under wetland condition. Application of Nitrobenzene at different concentrations with RF showed significant effect on rice growth and yield. At both locations, foliar application of Nitrobenzene (2 mL L-1) + RF gave higher number of tiller/m2, panicle/m2 and grain/panicle over RF. At Gazipur site, Nitrobenzene (2 mL L-1) + RF resulted in significant increase of grain and straw yield of BRRI dhan89 over the RF only whereas, at Satkhira site, no significant yield benefit with Nitrobenzene was found over RF. In terms of rice growth, yield and economic point of view, foliar application of Nitrobenzene at low concentration (2 mL L-1) with recommended fertilizer showed positive effect on the growth and yield of BRRI dhan89 in this study. However, since Nitrobenzene is a new type of plant stimulant, detailed studies on its mode of action, interaction with other plant growth hormones and environmental effects are required to get an insight on rice response to Nitrobenzene and its widespread application in rice cultivation.
