“…These results are similar to those of [5], who states that the labour factor has a positive effect on rice production. Indeed, the growth, development, and yield of crops, as well as the factors that affect them, occupy a position of primary importance in crop production [28]. Moreover, growth and yield are physiologically correlated and depend mainly on the expansion of planting areas, the increase in the input of material factors, and the gradual growth of productivity [29].…”

AIM: Assessment of various fertilizers type effects on rice productivity in Niger. Study Design: The experiment was laid by using a complete randomized block design with different types of fertilizers and was replicated four times. Place and Duration of Study: The field experiment was conducted during the dry and wet season of 2020 on the irrigated perimeter of Toula (Niger). Methodology: The experiment was performed with four treatments in complete randomized blocks. The treatments applied are: T1=Bokashi, T2=Compost, T3=Biochar and T4=NPK-Urea. The monitored parameters were the rice plant development cycle and agronomic characteristics. Observations of the crop evolution during the experimentation were recorded at regular intervals. The significance of treatment impact was examined by the statistical test. Results: The results showed that bio-fertilizers had significant effects on 1000 grain weight and the length of the vegetative cycle. As for the chemical treatments, the effects were significant on most of the rice growth parameters (height, number of grains per panicle, number of tillers per rice plant) as well as on paddy and feed biomass yield. These results also showed a positive correlation between rice growth parameters and yield irrespective of the type of treatment.

Previous researchers have focused on the role of 24-epibrassnolide (EBR) in alleviating stresses in plants, whereas the effect of EBR on rice grain yield formation from the perspective of the whole growth stage remains less concerned. To further confirm the optimal application concentration and application periods of EBR in rice (Oryza sativa L.) under salt stress, a seed germination experiment, a seedling experiment, and a pot experiment were designed and conducted. Results showed that EBR treatment significantly enhanced germination indicators and seedling morphological traits, and the effects varied among different EBR concentrations, which were 0.5 > 1.0 > 0.1 > 0.05 mg L−1. Under 0.5% salt treatments, 0.5 mg L−1 EBR spraying significantly enhanced the seedling height, root length, above-/under-ground fresh weight, and above-/under-ground dry weight by 9.2%, 15.9%, 48.0%, 19.5%, 29.3%, and 12.5%, respectively. The spraying of EBR at different periods enhanced rice yield by 6.7% to 94.4% under salt stress. The relatively higher panicle number (increased by 42.9%) and spikelet number per panicle (increased by 96.1%) were the main reason resulting in higher grain yield under the S+T5 (EBR sprayed at both transplanting and heading stage) treatment. Compared to those under S treatment, catalase (CAT) activity was significantly enhanced by 25.0%, while malondialdehyde (MDA) content was dramatically decreased by 37.3% under the S+T5 treatment. The S+T5 treatment significantly enhanced the K+ content in rice root and leaf and decreased the Na+ content in rice root (by 30.4%), thereby leading to higher K+/Na+ under salt stress. The current study concluded that 0.5 mg L−1 was the optimal concentration of EBR in alleviating the adverse effect of salinity. Spraying (transplanting + heading) of EBR twice displayed the best alleviating effect under salt stress, which was realized through enhanced antioxidant enzyme, higher K+ maintenance in leaves, and lowered absorption of Na+ in rice root.
