“…Under recommended fertilization, rapeseed yields were comparable between the CR and RR rotations, but without N fertilization, the oilseed rape seed yields following rice cultivation were significantly lower than those following cotton, a result similar to those reported for other crops [25][26][27]. Although rapeseed yields varied with different environmental variables [28], there was only one season's result, the experiments were located in different counties, and the weather conditions at the specific sites were different.…”

Differences in soil physical, chemical and biological properties between paddy-upland and continuous upland rotations will influence nutrient relations and crop growth. With the aim of estimating rapeseed yield performance in response to fertilization in rice-rapeseed (RR) and cotton-rapeseed (CR) rotations, on-farm experiments were conducted at 70 sites across Hubei province, central China. The economically optimal fertilizer rates of winter oilseed rape in different rotations were determined. Field experiments showed that previous crops significantly influenced seed yields. Without N fertilization, seed yields were significantly lower for the RR rotation than for the CR rotation. The average yield increase ratio and agronomic efficiency associated with nitrogen (N) fertilization in the RR rotation were 96.6% and 6.56 kg kg −1 , significantly higher than those in the CR rotation. No seed yield differences were detected between the two rotations under phosphorus (P) and potassium (K) fertilization. In contrast to the CR rotation, N fertilizer played a more vital role in maintaining high seed yields in the RR rotation owing to the lower indigenous soil N supply. Compared with local N fertilizer recommendation rates for the RR rotation, on average an additional 18 kg N ha −1 was recommended according to the economically optimal N fertilizer rate (EONFR). In contrast, the EONFR was 14 kg N ha −1 lower than the locally recommended N fertilizer rate for the CR rotation. There were no differences between the two rotations for the average economically optimal P and K fertilization rates.Consequently, the average EONFR of winter oilseed rape could be reduced if cotton rather than rice preceded the winter oilseed rape.Please cite this article as: T.

“…As ZT takes advantage of residual moisture from the previous crop, water use is decreased by~10 cm¨ha´1 (~1 million L¨ha´1¨year´1). There was no yield advantage of growing crops on beds compared with flat areas under rice-wheat system on permanent beds, and there was little advantage in water savings [96][97][98].…”

Despite years of study and substantial investment in remediation and prevention, soil erosion continues to be a major environmental problem with regard to land use in India and elsewhere around the world. Furthermore, changing climate and/or weather patterns are exacerbating the problem. Our objective was to review past and current soil conservation programmes in India to better understand how production-, environmental-, social-, economic-and policy-related issues have affected soil and water conservation and the incentives needed to address the most critical problems. We found that to achieve success in soil and water conservation policies, institutions and operations must be co-ordinated using a holistic approach. Watershed programmes have been shown to be one of the most effective strategies for bringing socio-economic change to different parts of India. Within both dryland and rainfed areas, watershed management has quietly revolutionized agriculture by aligning various sectors through technological soil and water conservation interventions and land-use diversification. Significant results associated with various watershed-scale soil and water conservation programmes and interventions that were effective for reducing land degradation and improving productivity in different parts of the country are discussed.

“…PBW343, a mega variety grown under conventional systems in India, produced the highest yield on the raised bed system. Raised bed technology for wheat is still in its infancy of development and it is too early to draw conclusions on the potential of the system in India (Singh et al 2009). In the bed-planting system, roots are concentrated in the top part of the beds, which dries faster.…”

An experiment, in which wheat was grown on raised beds, was conducted during rabi seasons (at the Research Farm of the CCS Haryana Agricultural University, Hisar. The experiment had six nitrogen (N) application timings (full dose at sowing, 1 = 2 dose at sowing þ 1 = 2 dose at first irrigation, 1 = 3 dose at sowing þ 2 = 3 dose at first node stage, 1 = 3 dose at sowing þ 1 = 3 dose at first irrigation þ 1 = 3 dose at first node stage, full dose at first node stage and full dose at crown root initiation stage) as main effects and five wheat varieties: PBW343, WH711, WH542, WH283 and HD2687 as sub-effects. Growth, N uptake, yield and yield attributes of wheat were significantly higher under split (two or three) applications of N as compared to N applied as a single application. Amongst the varieties, PBW343 had the highest yield. The variety had vigorous growth in terms of plant height and dry matter accumulation, which eventually produced significantly higher effective tillers, higher number of grains per head and higher grain weight per head and ultimately significantly higher grain and straw yields.
