A field experiment was conducted to evaluate the effect of tillage practices, residue management and cropping system on soil properties at NMRP, Rampur, Chitwan from November 2015 to April 2016. The experiment was laid on Strip split design with combination of 12 different treatments i.e, zero tillage & conventional tillage as main plot in the strip, residue retention & residue removal as sub-plot factor and maize – wheat, maize + soybean – wheat & soybean – wheat cropping system as sub-sub plot factor. Three replications of the treatments were made. Soil sample before experiment and after harvest of wheat was taken (0-15cm). The experiment showed significant effect of zero tillage on organic carbon (2.169%) and on total soil nitrogen (0.112 %). Zero tillage with retention of residues is valuable tool for the conservation agriculture and helps in sustainability of soil however long-term research for the tillage management and residue retention should be conducted to highlight the major effects on change in properties of soil.Int.

The effects of two tillage methods (zero tillage and conventional tillage), two residue managements (residue kept and residue removed) and two levels of cropping system (maize + soybean and sole maize) were studied over 3 years (2015-2017) at Dailekh district of Nepal. Arun-2 and Puja were the varieties of maize and soybean used respectively, followed by winter wheat. The results revealed that the maize + soybean system had significantly higher plant population and ear population (34.83 thousands ha-1 and 34.35 thousands ha-1, respectively), grains per row (37.1), ear length (16.6 cm) and 20.5% higher grain yield as compared to sole maize. The highest maize equivalent yield (7.92 t ha-1) was recorded in maize + soybean as compared to the lower grain yield equivalent (7.06 t ha-1) in sole maize. Zero tillage accounted relatively higher benefits (high net income and B:C ratio) as compared to conventional tillage. The residue kept plot resulted significantly higher B:C ratio (2.41) than the residue removed (2.11) and the maize + soybean recorded 82.5% greater B:C ratio compared to sole maize. Net annual income was significantly higher in zero tillage, residue kept and maize + soybean system (NRs. 223072.00, 222958.00 and 269016.00 ha-1 respectively). Such combinations are recommended for Dailekh district of Nepal to have profitable crop productivity. SAARC J. Agri., 17(1): 49-63 (2019)

Field experiments were conducted for four years (2014-2017) at five locations namely Salbani, Bhokraha, Simariya, Bhaluwa and Kaptanganj of Sunsari district to assess the changes in soil chemical properties under conservation agriculture (CA)-based practices in two cropping systems namely rice-kidney bean-maize at Salbani and rice-wheat at rest of the locations. In rice-wheat cropping system, there were four treatments: (1) conventional tillage (CT) for rice transplantation and subsequent wheat sowing, (2) conventional tillage rice transplantation followed by zero tillage (ZT) wheat, (3) unpuddled rice transplantation followed by zero tillage wheat, (4) zero tillage in both rice and wheat. Similarly, in rice-kidney bean-maize cropping system, there were four treatments; (1) conventional tillage for rice transplantation and sowing of both kidney bean and maize, (2) conventional tillage rice transplantation followed by zero tillage in both kidney bean and maize, (3) unpuddled rice transplantation followed by zero tillage in both kidney bean and maize, (4) zero tillage in all three crops. Soil samples were taken at initial and every year after rice harvest.The soil samples were analyzed for total nitrogen, available phosphorus, available potassium, pH and soil organic matter.Total nitrogen (N) showed a slightly decreasing trend in the first three years and showed a slight increase at the end of experiment under ZT in all locations. The total N under ZT changed from 0.12 to 0.13%, 0.05 to 0.06%, 0.10 to 0.12%, 0.11 to 0.08% and 0.09 to 0.13% in Salbani, Bhokraha, Simariya, Bhaluwa and Kaptanganj, respectively.  All locations showed the positive values of available potassium; Salbani  revealing considerable change of 64.3 to 78.5 mg/kg in CT while 68.4 to 73.3 mg/kg in ZT condition. The treatment where rice was transplanted in unpuddled condition and zero tilled to wheat, had a mean value of available phosphorus and potassium as 87.3 and 81.9 mg/kg respectively. Soil pH ranged from 4.8 to 7.1 in CT while it was 5.2 to 6.8 in ZT across the locations. The change in soil organic matter in CT of all locations except Salbani was narrower as compared to ZT.

A field experiment was conducted during Kharif and rabi seasons of 2015 and 2016 at farmer’s field of Banka District as an On Farm Trial to study the crop residues management with different crop establishment methods in rice (Oryza sativa L.)–wheat (Triticum aestivum L.) cropping system. Treatment comprised two levels of crop residue management ie. residue removal and residue retention (33%) and three levels of crop establishment methods ie. (a) conventional puddled transplanted rice fb conventional-till wheat (PTR-CTW), two times ploughing with cultivator followed by two times puddling and one planking was done before the manual transplanting of 21 days old seedling at 20 cm spacing from row to row. After rice harvesting, wheat was sown by broadcasting in conventional tillage plots with two times harrowing with cultivator followed by one planking; (b) unpuddled transplanted rice fb zero-till wheat (UPTR-ZTW): two times ploughing with cultivator followed by planking, after that water is submerged for transplanting and wet tillage was avoided. 21 days old rice seedlings were transplanted at a spacing of 20 x 15 cm. Wheat crop was sown under ZT using zero tillage machines; (c) zero-till direct-seeded rice fb zero-till wheat (ZTDSR-ZTW): direct-seeding of rice was done using zero-till seed-cum-fertilizer drill in ZT-flat plots at 20 cm row spacing. Wheat crop was sown in zero tillage using zero till machine. Rice variety (Rajendra Sweta) was sown directly by zero till in ZTDSR-ZT plots in the first fortnight of June. On the same date, rice seedlings for transplanting were raised in nursery by ‘Wet bed method’. Experiment was conducted in a split plot design which is replicated by thrice. Grain/panicle or spike, panicle or ear length and effective tillers/m2 recorded more in residue retention treatment and it was registered significantly superior with residue removal treatment under crop residue management in rice and wheat crop during both the years of experiment. Amongst crop establishment method, ZTDSR-ZTW was recorded more Grain/panicle or spike, panicle or ear length and effective tillers/m2 and it was significantly superior with UPTR-ZTW and PTR-CTW treatments under crop establishment methods in rice and wheat crop during both the years of experiment. Residues retention (33%) significantly improved the grain yield of both the component crops. For rice crop, 8.2–10.0% higher grain yield was realized with retention of crop residues. Grain and straw yield of rice were registered more in ZTDSR-ZTW (3.86-3.99 t/ha) & (5.56-5.75 t/ha) closely followed by UPTR-ZTW (4.38-4.45 t/ha). Concerning the data of residue management on economics revealed that the residue retention was recorded more gross return, net return as well as B: C ratio followed by residue removal treatment in both years of experimentation for rice and wheat crop and ZTDSR-ZTW was recorded more gross return, net return as well as B: C ratio followed by UPTR-ZTW and PTR-CTW treatments under crop establishment methods in rice and wheat crop during both the years of experiment.

In order to find out the efficacy of conservation tillage on yield and economics of fodder crops over conventional tillage in new alluvial zone of West Bengal, a field experiment was conducted at Central Research Farm, Gayeshpur, West Bengal, India during summer season of 2016 and 2017 comprising 3 tillage practices (T1: zero tillage, T2: minimum tillage, T3: conventional tillage) in main plot and 4 fodder crops (C1: maize, C2: sorghum, C3: rice bean, C4: cowpea) in subplot and replicated thrice in a split plot design. Mean data confirmed the superiority of conservation tillage over conventional tillage in improving soil status and thereby, crop performance. Cereal crop maize when grown under zero tillage produced highest green forage yield (42.33 t/ha), dry matter yield (7.84 t/ha). However, regarding crude protein yield, cowpea showed superiority over others specially when grown under zero tillage condition (1.071 t/ha). Mean data also stated that legume crops under conservation tillage remained economically more viable than cereal crops. Specifically, cultivation of cowpea under zero tillage condition was economically most profitable (B:C of 2.21) and therefore can be recommended in this region.

Weeds are often harmful to crop growth due to the competition for space and resources. A field experiment containing four treatments with three replications in a complete randomized design was conducted at Yucheng Comprehensive Experiment Station, Chinese Academy of Sciences since 2008 to assess the impact of shifting from conventional tillage to no-till with crop residue management on weeds and wheat production at the North China Plain. We found that both aboveground weed density and species richness were higher under continuous no-till (NT) than conventional tillage (CT) in the regrowth and stem elongation stage of wheat growth. On the other hand, aboveground weed density in the stage of flowering and filling decreased with crop residue mulching. The density of the soil seed bank in crop residue removal treatments was significantly higher than that of crop residue retention. Besides, either crop residue mulching or incorporating into the soil significantly increased the wheat yield compared with crop residue removal regardless of tillage management. In conclusion, crop residue retention could decrease the weed density and species richness both aboveground and in the soil seed bank and inhibit the growth of broadleaf weeds by the residue layer. Moreover, crop residue retention could improve the wheat yield.

Pearl millet-based cropping systems with intensive tillage operations prior to sowing have limited sustainable productivity in the low-irrigation conditions of semi-arid farming ecologies, such as those in the north Indian plains. The adoption of improved management practices such as zero tillage with residue retention (ZTR) and diversification with the inclusion of summer pulse crops has the potential to improve cropping system sustainability. Therefore, an experiment was designed to compare two improved management practices, zero tillage (ZT) and ZTR, to conventional tillage (CT), across three pearl millet-based cropping systems: pearl millet–chickpea (PM–CP), PM–CP–mungbean (MB), and PM–CP–forage pearl millet in a two-year experiment. Experimental treatments were compared in terms of pearl millet productivity, mineral biofortification, and greenhouse gas emissions. Results showed a significant increase in pearl millet yield attributes, grain and stover productivity, nutrient uptake, and micronutrient biofortification in the PM–CP–MB cropping system under ZTR relative to other treatment combinations. On-farm evaluation at different locations also showed that the intensification of PM–CP system using summer crops enhanced pearl millet productivity across diverse tillage systems. Overall, zero tillage practices combined with diversified pearl millet-based cropping systems are likely to be management practices, which farmers can use to sustainably maintain or increase cropping system productivity in the various semi-arid areas of the world.

The severe limitation of agricultural land productivity induced by physical soil degradation has become a major concern in semiarid climates, especially in the Eastern Cape Province, South Africa. A randomized complete block design in a split-split-plot arrangement was used to evaluate the short-term (2012–2015) effects of tillage (no-till (NT) and conventional tillage (CT)), rotation (maize-fallow-maize (MFM); maize-fallow-soybean (MFS); maize-wheat-maize (MWM) and maize-wheat-soybean (MWS)) and residue management (residue removal (R−) and residue retention (R+)) on bulk density (BD), penetration resistance (PR), soil hydraulic conductivity (Ks) and macroporosity hydraulic conductivity. The interaction of tillage × crop rotation × residue management was not significant (p > 0.05) with respect to BD, PR, Ks and macroporosity. The MFM rotation had the highest BD (1.40 g cm−3), followed by MWM rotation (1.36 g cm−3), and the least BD was observed in the MFS rotation (1.29 g cm−3). Penetration resistance was significantly higher in CT (2.43 MPa) compared to NT (1.46 MPa). The study concludes that inclusion of MFS and MWS rotations can potentially reduce BD in the short term. Similarly, conversion from CT to NT reduces soil resistance.

A field experiment was conducted at the research farm of the Directorate of Wheat Research, Karnal (Haryana) during 2007-08 to 2009-10 with the objective to compare the whole basal and split application of nitrogen under different residue management and tillage options in rice-wheat cropping system. Combined analysis of data revealed that puddled transplanted rice produced maximum rice grain yield, straw yield, thousand grain weight and grains /panicle. Rice yield under zero tillage was decreased to the tune of 27.8% (with residue), 33.9% (without residue) and 45.3% (under permanent bed planting) as compared to puddled transplanted condition. Split application of nitrogen increased the rice grain yield to the extent of 4.7% with residue, 8.0% without residue and 10.2% under puddled transplanted condition as compared to whole basal N application. Pooled analysis under zero tillage condition, retention of rice residue enhanced the wheat grain yield 21.3% at zero N, 8.3% at 150 N (whole basal) and 5.4% at 150 N (three split) applications. Application of nitrogen in three split doses increased the wheat grain yield up to 9.6% without residue retention and 6.7% with rice residue retention condition as compared to whole basal N application. In nut shell, it can be said that adoption of zero tillage, residue retention and whole basal N application did not work well for rice whereas it was better for wheat in rice-wheat system.SAARC J.

Rice-wheat system provides food, income, and employment to over 83 % of the people and contributes to national food security in Nepal. Sustainability of the system is under threat because of increasing cultivation cost and declining soil fertility. On-farm experiments were carried out to determine the effects of tillage and crop establishment methods, crop residue management, and nitrogen levels that affect soil attributes and productivity of the rice-wheat system during 2010- 2011at Bara, Nepal. The treatment consisted of three tillage and crop establishment methods viz. Conventional tillage (CT), Permanent bed planting (PB), and Zero-tillage (ZT); two residue management levels viz. Residue retention and Residue removal; and three nitrogen levels viz. Zero nitrogen, farmer’s dose (80 and 100 kgha-1 N for rice and wheat, respectively), and abundant nitrogen (120 kgha-1 N for both rice and wheat crop). The experiments were laid out in strip-split plot design with three replications. The research results revealed that rice grain yield was significantly higher in the plots receiving N level as applied by farmers that was similar to abundant nitrogen dose. Wheat grain yield was significantly higher with zero tillage compared to permanent bed planting and conventional tillage. Significantly higher wheat grain yield was also obtained due to abundant nitrogen dose than zero dose nitrogen which was similar to farmers’ dose of N as well. There was no significant difference in grain yield of rice and wheat due to residue retention, although, it improved soil moisture. In wheat crop, zero-till planting and increased nitrogen application conserved soil moisture, enhanced soil electrical conductivity and lowered soil temperature. It can be concluded that rice and wheat can be grown successfully with zero tillage and farmer’s nitrogen dose without any yield penalty.

Soil organic matter, nitrogen (N), phosphorus (P) and potassium (K) nutrition of rice-maize cropping systems are important for sustaining crop productivity and food security. An experiment was conducted to determine the effects of tillage practices and residue retention on soil chemical properties in rice-maize cropping system. Conventional tillage, single pass wet tillage in rice (rotated with zero tillage in maize), bed planting (unpuddled rice transplanting) and strip tillage (unpuddled rice transplanting) in vertical plots and residue retention (0, 50 and 100%) in horizontal plot were tested for three consecutive years (2009-12). Rice was grown as transplanted irrigated crop and maize as upland crop. After third crop, strip tillage increased soil organic matter compared to bed and zero tillage at 0–7.5 cm soil depth. After three years, retention of crop residues, irrespective of tillage treatments, increased soil organic matter (SOM) at 7.5–15.0 cm soil depth. Tillage practices (puddled or unpudled) showed no significant changes in SOM. Neither tillage nor residue management had any significant effect on soil pH, total nitrogen, available phosphorus and exchangeable potassium.DOI: http://dx.doi.org/10.3329/agric.v13i2.26589The Agriculturists 2015; 13(2) 62-73
