Roots of rice (Oryza sativa L.) grown in stagnant de-oxygenated solution contain a 'tight' barrier to radial oxygen loss (ROL) in basal zones, whereas roots of plants grown in aerated solution do not. It is generally accepted that the barrier to ROL involves anatomical modifications in the apoplast of cell layers exterior to the aerenchyma. A possible drawback of this adaptation is a reduced capacity for nutrient uptake. Whether or not induction of a barrier to ROL influences the capacity of adventitious roots of rice to take up NO3– was determined in the present study, using NO3–-selective microelectrodes. When transferred into O2-free root medium, ROL from positions at 30–50 mm behind the tip of adventitious roots of plants raised in stagnant solution was only 4–6% of the rate from roots of plants raised in aerated solution, indicating the barrier to ROL was induced by growth in stagnant solution. For plants transferred into aerobic nutrient solution containing 0.1 mM NO3–, net NO3– uptake by these root zones, with or without a barrier to ROL, was the same. It is concluded that induction of a barrier to ROL had no effect on the capacity of adventitious roots of rice to take up NO3– from aerobic solution.

Salinity is the major factor reducing crop yield in coastal areas of Bangladesh. Proline (Pro) application with suitable crop varieties having higher yield potential could contribute to the improvement of crop production in saline areas. The main objective of this study was to investigate the mitigation of adverse effects of salinity in aman rice by exogenously applied Pro. The experiment was carried out at the farmer’s field of Batiaghata, Khulna. Characteristically, the soil was silty clay loam having pH 6.7, EC 4.6 dS m–1, CEC 23 meq/100 g soil, organic matter 0.71%. Rice (Oryza sativa L.) variety BR23 was used as plant material. The experiment was laid out in a randomized complete block design with three replications. There were different treatment combinations namely control (no Pro), 25 mM Pro at seedling stage, 25 mM Pro at vegetative stage, 25 mM Pro at seedling and vegetative stages, 50 mM Pro at seedling stage, 50 mM Pro at vegetative stage, 50 mM Pro at seedling and vegetative stages, 100 mM Pro at seedling stage, 100 mM Pro at vegetative stages, and 100 mM Pro at seedling and vegetative stages. Recommended doses of N, P, K, S and Zn fertilizers were applied to the all experimental plots. Thirty-day-old seedlings were transplanted in the experimental plots. Proline solutions were sprayed over plant leaves with the help of sprayer as per treatments. Salinity caused significant reductions in growth and yield of BR23 by decreasing plant height, number of effective tillers, panicle length, filled grains panicle-1 and 1000-grain weight. On the other hand, exogenous application of Pro showed a significant increase in growth and yield of BR23 under saline conditions. Results also revealed that growth and yield of rice did not increase proportionally with the increasing doses of Pro. Proline application resulted in significant increases in K+/Na+ and nutrient uptake by rice under salinity. The present study suggests that exogenous application of Pro confers tolerance to salinity in aman rice by increasing K+/Na+ ratio and nutrient uptake. J. Bangladesh Agril.

The study of packages of semi-organic fertilization on soil properties, and yield of rice (Oryza sativa L). The aim of this study was to know the effect of semi organic fertilization doses on soil properties and yield of rice. The Randomized block design (RBD), with 3 replications and 9 treatments was used in this study. P0 (without fertilizer), P1 (25 tons of organic fertilizer ha-1), P2 (300 kg of Urea ha-1, 150 kg SP36 ha-1 and 75 kg KCl ha-1), P3 (biourin liquid fertilizer) P4 (½ P1 + ½ P2), P5 (½ P1 + ½ P3, P6 (½ P2 + ½ P3), P7 (2/3P1 + 1/ 3 P2) and P8 (2/3P3 + 1/3P2). The results showed that the application of semi-organic fertilizer on soil properties such as soil salinity, C-organic content, P-available and Nitrogen content of soil significantly affected by the treatment, while potasium_available and soil pH is not significantly affected by the treatment.  Yield of rice had a very significant effected by treatment. The semi-organic fertilizer P4 (combination of 50 % anorganic + 50 % organic compost) and P6 (combination of 50 % inorganic + 50 % biourine) can produce oven dry grain 33.35 g per bushel and 32.63 g per bushel respectively or increased 57.91 % and 54.50 % of controls.
