Abstract: Irrigated rice cultivation has a prominent place in the Senegal River Valley, with the double-cropping system based on old varieties. However, in a context of climatic variability, the system shows limitations in relation to production requirements, resulting a negative impact on rice yields. Therefore, a study was conducted to evaluate the effects of sowing date and sowing method on the yield of some varieties during the low-temperature periods of the year between december and february.

Abstract: The study analyzed the MNC phenomenon according to the experience of caring for some patients admitted to the surgical area in a surgical department of a second-level hospital in northern Italy in order to determine which elements of nursing care might be delayed or omitted.

Abstract: The role of rice ( Oryza sativa ) plants themselves at facilitating methane (CH 4 ) emissions from flood-irrigation has been well-established. However, as alternate water management schemes, such as furrow-irrigation, grow in use, the role of rice plants facilitating CH 4 and nitrous oxide (N 2 O) emissions needs to be evaluated.

Abstract: In other hand, Results shows that- High concentrations of toxins in the soil environment strongly inhibited the activity of Phosphatase enzymes in the roots, in the indicator leaves, and especially for rice, especially for plants that are less resistant to poisoning. But, Phosphatase enzyme in leaves has the effect on the providing energy for the plants to recover from poisoning. The activity of this enzyme is inversely correlated with the content of Al3+ in soil and Al3+ in plants. This proves that the antagonism between enzymes and toxins is evident, especially with Al3+ toxins.

Abstract: Phosphorus (P) is an essential plant macronutrient that is commonly applied as a fertilizer for optimal crop production. As the global supply of fertilizer-P sources, mainly derived from mined rock phosphate (RP), is decreasing, alternative nutrient sources need to be developed and tested, such a wastewater-recovered struvite-P materials. The objective of this greenhouse study was to evaluate below- and aboveground rice ( Oryza sativa ) response to various fertilizer-P sources

Abstract: A Field experiment was conducted at Zigau, Shira Local Government Area of Bauchi State to study the performance of lowland rice as influenced by combine effect of season and sowing pattern. Lowland rice variety FARO 44 (Sippi 692033) was used during the study. The treatments consisted of two seasons (dry and wet) and four different sowing patterns (Transplanting, Dibbling, Drilling and Broadcasting). This gave eight treatments combination which were factorially combined and laid in Randomized Complete Block Design (RCBD) replicated four times.

Abstract: The study investigated performance effects of biochar concentrations and fertilizer types on drip irrigated upland rice for two seasons. A Randomized Complete Block Design (RCBD) comprising of four levels of biochar application (0 t/ha, 5 t/ha, 10 t/ha and 15 t/ha) and four fertilizer types (Liquid Organic Fertilizer, NPK 15:15:15, poultry manure, and control) with drip irrigation system and thrice replicated was conducted. Agronomic parameters such as plant height, stem girth width, leaf area, number of leaves, yield and others were measured. Treatments NPKB15, PMB15 and LOFB15, in that order, performed better than F0B15 and F0B0 in all the agronomic parameters in the two seasons.

Abstract: In Ethiopia, the current rice productivity is very low which is attributed to different abiotic and biotic constraints significantly impacting rice productivity particularly in the north western parts of the country. In an effort to improve the productivity of rice, the national rice breeding program of the country is introducing and evaluating different rice germplasms targeting their adaptability and agronomic performance.
