“…A significant increase in yield of rice and wheat with residues incorporation in this study was also in line with the results of Dotaniya (2013), who observed significant increase in rice (4%) and wheat (49%) with residue incorporation as compared to residue removal. Increase in grain and straw yield of wheat and rice with incorporation of both wheat and rice crop residues was also observed by, Sarkar (1997), Prasad et al (1999), Sarkar and Kar (2011) and Davari et al (2012). Gupta et al (2007) reported that straw incorporation tended to increase wheat yield, not significantly, after two years and reached the significant difference after four years, as compared to control.…”

Heavy tillage in rice-wheat (RW) system has been resulting in deterioration of soil structure consequently reducing farm productivity. In situ burning of crop residue after combine harvesting further aggravates the problems. Hence, wise crop residue management practices (CRMPs) can be a better option for sustainable productivity in the RW system. Different CRMPs (residue removal (RR); residue burning (RB), residue incorporation (RI) and zero-tillage (ZT)) were investigated for four cropping seasons under field conditions in RW area at two farmers' fields. Rice paddy (12%) and straw (4%) yields and wheat grain (17%) and straw (3%) yields were generally higher at Ratta Ber Farm than Shahbaz Farm. Among various CRMPs, RI produced significantly higher paddy and straw yields of rice and grain and straw yields of wheat. Nitrogen (N), phosphorus (P) and potassium (K) uptake in rice as well as in wheat was significantly higher with RI as compared to other CRMPs. N, P and K uptake in wheat was 15, 11 and 11% higher, at Ratta Ber Farm as compared to Shahbaz Farm, respectively. Soil NO3-N and P2O5 contents were significantly higher with RI followed by ZT as compared to RR and RB at both sites. Soil K2O contents were significantly higher with RB, RI and ZT as compared to RR at both sites. The results revealed that there was improvement in soil nutrients by crop residue incorporation as well as zero-tillage at both sites, however crop productivity improved only by crop residue incorporation.

“…On the other hand, the energy use ratios in agricultural production are closely related with production techniques, quantity of input, yield level and environmental factors. It was also reported that large farms used energy in the best possible way to achieve maximum yield than the small size farm (Sarkar, 1997;Shearer et al, 1981;Sims et al, 2006…”

“…Crop residues contain large quantities of K, and their recycling can markedly increase K availability in soils (Chatterjee and Mondal, 1996;Sarkar, 1997). Recycling of crop residues can improve crop yields at low rates of K application and can decrease crop response to applied K. Yadvinder- reported that release of K from rice straw occurred at a fast rate, and available soil K content increased from 50 mg (kg soil) -1 in the untreated control to 66 mg (kg soil) -1 in straw-amended treatments within 10 d after incorporation.…”

Tiwari et al (1992) also reported that most of K in the rice residue was released in less than 41 d while Sarkar (1997) concluded that the amount of K released from organic materials in the first month was highly correlated with the watersoluble K. Mishra et al (2001) reported that about 79% of total K in rice straw was mineralized within 5 weeks after incorporation and 95.3% by the end of 23 weeks. Yadvinder- Singh et al (2010) reported that 85%-88% of K from buried rice residue had been released at maximum tillering while more than 97% at the end of the decomposition cycle during the wheat season.…”

Potassium (K) availability in soils is largely governed by their mineralogical composition. The extent of weathering of primary K-bearing minerals, the chemical pathways through which weathering takes place, as well as the dynamic equilibrium between various K fractions in soils are factors which determine different soil types of varying K-supplying capacity. The marked variability of K availability in soils in South Asia needs to be taken into account when formulating K-management strategies in intensive cereal-based systems in response to K application. Evidence from long-term fertilizer experiments in rice-rice (R-R) or rice-wheat (R-W) systems strongly indicates significant yield responses to K application and negative K balances where K application is either omitted or applied suboptimally. However, K-fertilizer recommendations in South Asia are generalized over large areas while farmers neglect K application to crops and remove crop residues from fields. These practices may strongly affect yield and soil K-fertility status in the emerging rice-maize (R-M) systems in different locations of South Asia. The dry-matter yield of the R-M system is usually much higher than that of the R-R or R-W system causing high withdrawal of nutrients from the soil. The current review assesses various K forms and K availability in diverse soil types of South Asia supporting rice-based systems. Aspects considered include: long-term crop yield and its response to added nutrients, K balance for intensive rice-based systems, and the role of crop residues in supplying K to crops. Emerging data from either completed or on-going experiments on the R-M systems in India and Bangladesh have revealed very high system productivity and variable responses and agronomic K-use efficiency of maize and rice. Potassium responses of maize are extremely high and variable for soils in Bangladesh. Finally, a plant-based strategy for field-specific nutrient management is presented and the need for models and decision support systems for developing efficient K management of the R-M system is also discussed.
