“…2(J)). This result was similar to a previous study, 35 where the interactive effect between the intercropping pattern and N fertilization significantly affected plants growth, which was attributed to legumes. Overall, the NB treatment was most conducive to rice growth, and N fertilizer application also facilitated rice and water mimosa growth.…”

BACKGROUND: Cereal-legume intercropping systems are an environmentally friendly practice in sustainable agriculture. However, research on the interspecific interaction of nitrogen (N) between rice and aquatic legumes has rarely been undertaken. To address this issue, a pot experiment was conducted to investigate N utilization and the N interaction between rice and water mimosa (Neptunia oleracea Lour.) in an intercropping system. The root barrier patterns consisted of solid barrier (SB), mesh barrier (MB), and no barrier (NB) treatments. The N fertilizer application rates were low, medium, and high N rates. RESULTS:The results showed that the NB treatment better facilitated rice growth compared with the MB and SB treatments. And the nitrate N content and urease activity of rice rhizospheric soil in the NB treatment were the highest of the three separated patterns. The ammonium N content in water mimosa rhizospheric soil and N 2 fixation of water mimosa ranked as NB > MB > SB.CONCLUSIONS: The amount of N fixation by water mimosa was 4.38-13.64 mg/pot, and the N transfer from water mimosa to rice was 3.97-9.54 mg/pot. This can promote the growth of rice and reduce the application of N fertilizer. We suggest that the rice-water mimosa intercropping system is a sustainable ecological farming approach and can be applied in the field to facilitate rice production.

“…T7 (16.4 kg/ha N) gave the maximum yield than T14 (19 kg/ha N) this could be because of excessive nitrogen had been reported to reduce fruit number and yield for sesame but enhances plant growth [12]. Similarly this finding agreed with the report of [9] that indicates the highest seed yield (750.4kg ha -1 ) was recorded from the interaction level of 60-30NPkg ha-1 and 5t ha -1 FYM, and the lowest seed yield (480.6kg ha -1 ) was recorded from zero level of NP and FYM main factors [18][19][20][21][22][23][24].…”

Field trials on sesame were conducted at the Fadis Agricultural Research Station during the 2014 and 2015 cropping seasons to determine the optimal rate of Nitrogen(UREA) fertilizer and Phosphorus(DAP) for sesame production. The experiment consisted of four rates of Nitrogen in the form of UREA (0, 40, 60, &80kg ha -1 ), and four levels of Phosphorus in the form of DAP (0, 10,20&30kg ha -1 ) applied to the treatments. The sixteen treatment combinations were laid out in a RCBD design with three replications. Yield of Sesame and yield related components were showing significant difference (p<0.05). Analysis of variances showed that grain yield, number of capsule per plant, number of seeds per capsule and number of branching per plant was significant differences at (P<0.05) both at Fadis and Erer of study areas. Grain yield increases from 518.1kg/ha to 891kg/ha as N increases from 0(control) to 24.6kgN (60kgDAP @ 30kgUREA).

Intercropping of Rice and Water Mimosa (Neptunia oleracea Lour.): A Novel Model to Control Pests and Diseases and Improve Yield and Grain Quality while Reducing N Fertilizer Application

Cereal/legume intercropping is an effective agricultural practice for pest and disease control and crop production. However, global research on rice and aquatic legume intercropping is relatively rare. A field experiment during two seasons (2018 late season and 2019 early season) was conducted to explore the effects of rice and water mimosa intercropping on rice canopy microclimate, pest and disease, yield, grain quality, and economic income. Two cultivation patterns including rice/water mimosa intercropping and rice monocropping were employed, and three nitrogen (N) fertilizer application levels, including zero N (ZN, 0 kg ha−1 N), reduced N (RN, 140 kg ha−1 N), and conventional N (CN, 180 kg ha−1 N) levels, were applied for the above two cultivation patterns. The results showed that rice/water mimosa intercropping formed a canopy microclimate of rice with higher temperature and lower relative humidity and dew point temperature. In addition, there was a significant reduction in the occurrences of rice leaf blast by 15.05%~35.49%, leaf folders by 25.32%~43.40%, and sheath blight by 16.35%~41.91% in the intercropping treatments. Moreover, rice/water mimosa intercropping increased rice per unit yield by 43.00%~53.10% in the late season of 2018 and 21.40%~26.18% in the early season of 2019. Furthermore, rice grain quality was totally improved, among which brown and head rice rates increased but rice chalky rate and chalkiness degree decreased in the intercropping system. We suggest that combining rice/water mimosa intercropping and N fertilizer reduction can be used as an environmentally friendly eco-farming technique because it can decrease N fertilizer application by approximately 40 kg·ha−1. This combination would not only mitigate nonpoint source pollution but also obtain advantages for controlling rice pests and diseases that would alleviate pesticide usage and improve rice yield and grain quality, which can be extended for green rice production to increase income for producers.
