“…The improved yield under rice upland crop rotation was accompanied by greater rice height, number of grains per panicle, and panicle number. These results are consistent with several other studies demonstrating rice yield increases with upland crop inclusion in rice based rotations (Filizadeh et al, 2007;Song et al, 2012;Xuan et al, 2012;Mandal et al, 2014).…”

“…The similar trends found in that study proof that the findings of this study, though based on data from one year only, are consistent and not greatly affected by market prices that vary over years due to supply-demand relation and inflation. Bastia et al (2008) and Mandal et al (2014) also reported a better net economic return with rice and upland crop rotation systems.…”

Biochar‐based nutrient management as a futuristic scalable strategy for C‐sequestration in semiarid tropics

Climate and agriculture experts emphasize the need to develop a carbon sink in the soil to help alleviate the effects of climate change. A 2‐year field experiment in semiarid tropical drylands tested sustainable nutrient management approaches to sequester carbon in the soil. We analyzed nine different treatments, including chemical fertilizers (as blanket and soil test‐based [STB] recommendations), sole organic (biochar and compost), and their combinations (with 75% and 50% STB recommendation) as integrated applications (integrated nutrient management [INM]) in the maize–chickpea cropping sequence. We report that biochar treatments show higher (24%–30%) organic carbon stock in the top layer of soil than the respective compost treatments. Furthermore, the biochar‐based INM showed the maximum residual effect in chickpea (Cicer arietinum L.) crops. The system equivalent yield showed the best results (8 Mg ha−1) for 50% need‐based fertilizer and 50% biochar. Although we observed that sole‐biochar sequestered the highest amount of soil organic carbon (0.69%) in the topsoil compared to the other treatments, it was not scalable due to the lower yield for maize crops. Similarly, composts showed more labile carbon concentrations as microbial biomass but lagged behind biochar treatments for organic carbon storage. The system performance expressed as net returns and benefits–cost ratio also showed better results for biochar‐based INM. The findings show that drylands facing widespread land degradation in terms of nutrient imbalances and low C levels will benefit from an integrated approach of need‐based fertilizer with biochar application. Therefore, this might be a long‐term sustainable strategy for C‐sequestration and food security for semiarid tropical drylands.

“…However, it would be desirable to determine if a high value pulse crop could be grown following rice to improve profitability, weed management and soil properties for successive rotations and, hence, the sustainability of the cropping system [18]. Production of leguminous crops following rice offers numerous potential advantages, including more efficient use of irrigation water in contrast to post-fallow [19] and reduction of weed pressure [8,20].…”

Weed Suppression and Performance of Grain Legumes Following an Irrigated Rice Crop in Southern Australia

et al. 2016

Post-rice irrigated soils offer several potential advantages for the growth of subsequent crops, but Australian producers have often been reluctant to grow grain legumes immediately following a rice crop due to physico-chemical constraints. A field experiment was thus conducted to explore the potential for producing grain legumes following rice in comparison to those following a fallow during 2012 and 2013. Two grain legumes, field pea and faba bean, were sown 5, 7 and 12 weeks after rice harvest in 2013 at Yanco, NSW, and plant growth indicators and grain yield were compared. Early sowing of field pea following rice gave the best outcome, with plants flowering three weeks earlier and yielding 1330 kg·ha −1 more grain than after fallow. In contrast, faba bean yield was 35 kg·ha −1 less after rice than after fallow across the three sowing dates. Higher pea yield was consistent with the early emergence of seedlings, higher light interception and overall greater plant growth following rice. Post-rice crops also had 10-fold less weed infestation than crops in a similarly-established fallow treatment and, thus, required far less weed management. Legume crops sown at the later seeding date had significantly reduced (~50%-60%) yields compared to those of the first two sowings; this is most likely a reflection of reduced temperatures and day lengths experienced during vegetative and reproductive growth phases.
