A field trial was carried out during July month of kharif and October month of rabi seasons of 2013-14 and 2014-15 at Agricultural Research Station, Bheemarayanagudi to study the effect of nutrient management through target yield approach on uptake and soil microflora in maize – wheat/chickpea sequence cropping system under different tillage practices. The results indicated that the yield parameters of maize, wheat and chickpea at harvest did not influence due to tillage practices. All these yield parameters were relatively higher in zero tillage with mulch at 5 t ha-1 when compared to conventional tillage. Grain and stover yield of maize did not differ significantly due to different tillage management practices. But, zero tillage with mulch at 5 t ha-1 produced relatively higher yield (65.9 q ha-1) than the zero tillage (64.3 q ha-1) followed by conventional tillage (55.8 q ha-1). The higher organic carbon and soil microflora at different stages were noticed with zero tillage with mulch at 5 t ha-1. The higher available NPK and their uptake by maize crop were also recorded in zero tillage with mulch at 5 t ha-1 followed by zero tillage compared to conventional tillage and zero tillage. The lower available NPK and their uptake by maize crop were recorded in conventional tillage and RDF. Further, due to nutrient management through target yield approach, the yield parameters of maize were differed significantly. Target yield of 10 t ha-1 exhibited significantly higher yield attributes at harvest when compared to other treatments except the targeted yield of 8 t ha-1 and 150% RDF. The lowest values of these attributes were recorded in farmer’s practice of nutrient management followed by RDF. The grain yield and stover yield (69.9 q ha-1and 89.5 q ha-1, respectively) of maize was significantly higher with a targeted yield of 10 t ha-1 followed by targeted yield of 8 t ha-1 and 150% RDF. The lowest grain and stover yield (53.6 q ha-1 and 74.3 q ha-1, respectively) was recorded in farmers practice followed by RDF. Significantly higher soil microflora, available NPK and their uptake by the maize crop was noticed in target yield of 10 t ha-1 followed by targeted yield of 8 t ha-1 and 150% RDF as compared to other treatments. The lowest soil microflora, available nitrogen, phosphorus, and potassium (NPK) and their uptake by the maize was recorded in farmers practice followed by RDF. The same trend was followed statistically for organic carbon due to different treatments. Non significant differences for grain and stover yield of maize was recorded due to interaction of tillage and nutrient management practices. Similar trend was also followed due to interaction of tillage and nutrient management practices for succeeding wheat and chickpea. The yield and yield parameters of wheat and chickpea did not differ due to tillage practices and target yield approaches followed for maize. Maize equivalent yield of wheat and chickpea and system productivity were followed same trend as that of maize yield. Among different tillage practices, zero tillage and zero tillage with mulch at 5 t ha-1 were recorded maximum net returns and higher BC ratio. Similarly, among different nutrient management practices, the target yield of 10 t ha-1 followed by targeted yield of 8 t ha-1 was recorded maximum net returns and higher BC ratio as compare to other treatments.

An ongoing field experiment established in 2012 at Agronomy Research Farm, Chaudhary Charan Singh (CCS) Haryana Agricultural University, Hisar, India was selected to evaluated the effect of three tillage practices (zero tillage, furrow irrigated raised bed system and conventional tillage with mouldboard plow ) and four weed management practices (W1: Atrazine (50% W.P.) at750 g/ha in maize and pinoxaden 50 g/ha + premix of metsulfuron and carfentrazone (Ally Express 50% DF) 25 g/ha + 0.2% NIS as post-emergence in wheat, W2: Tembotrione (Laudis 42% Sc @ 120 g/ha + S 1000 ml/ha (10-15 days/ 2-4 leaf stage) in maize and clodinafop 60 g/ha + metsulfuron 4 g/ha as post- emergence in wheat, W3: Two HW in maize (20 to 40 days) and wheat (30 to 50 days), W4: Weedy check in maize and wheat) on nutrient uptake and yield of wheat. Treatment was replicated thrice with spilt plot design. Plant samples were collected in the month of April, 2016 after the harvesting of wheat. Significantly higher yield of wheat was reported under FIRBS (66.1 qha-1) followed by zero tillage and under weedy check treatment as compared to other under different tillage and weed management practices. These results suggest that zero tillage and FIRBS along with the weedy check treatment results in higher wheat yield followed by maize.

A field experiment was conducted at Rampur, Nepal to see the effect of tillage, residue and nutrient management practices on soil properties and grain yield of rice. Three factors each with two levels i.e. tillage (with or without), residue (with or without) and nutrient management (recommended dose (RD) with 100:60:30 NPK kg ha-1 and farmer’s doses (FD) with 5Mt ha-1 of FYM + 50:23:0 NPK kg ha-1. Thus, altogether eight treatment combinations were evaluated under strip-split plot design with three replications. Higher soil organic matter was recorded in residue kept (5.73%) than the residue removed plots. Exchangeable potassium was found higher in no tillage (110.52 kg ha-1) than the conventional tillage (76.77 kg ha-1). Number of effective tillers was higher in no tillage; residue kept and recommended doses of fertilizer. Grain yield was significantly higher in no tillage with 3.66 Mt and residue kept with 3.72 Mt ha-1 compared to conventional tillage with 2.28 Mt and residue removed plots having 2.22 Mt ha-1. RD produced significantly higher grain yield of 4.53 Mt ha-1 than FD with 1.41 Mt ha-1. Therefore, untilled direct seeded rice with residue and recommend does of nutrients seem promising in Terai region of Nepal.

The field experiment was conducted with four tillage and three nutrient management practices at Agronomy field unit, University of Agricultural Sciences, GKVK, Bangalore, Karnataka, India. The results of the study indicated that, higher groundnut pod yield (1307 and 1282 kg ha-1) and haulm yield (2733 and 2889 kg ha-1) was recorded with mechanical tillage + two intercultivations and integrated application of 50% organics and 50% inorganics, respectively as compared to rest of the treatments. Further, the same treatments noticed higher availability of N, P2O5 and K2O in soil after harvest of groundnut, but greater improvement in soil organic carbon content was observed with conventional tillage + one intercultivation (0.62%) as compared to rest of the tillage practices. The maximum net returns and benefit-cost ratio was recorded with mechanical tillage + two intercultivations (Rs. 11,287 ha-1 and 1.75, respectively) and integrated application of 50% organics + 50% inorganics (Rs. 10,462 ha-1 and 1.69, respectively). However, interaction effect of tillage and nutrient management practices were not influenced significantly on soil fertility and productivity of groundnut under rainfed farming system.

An experiment was conducted in the rainfed Inceptisols of Rakhdhiansar in Kandi areas of Western Himalayas of South Kashmir and Kumaon, India for four years to assess the influence of combined use of tillage and nutrient management treatments on soil quality under maize based cropping system. The experiment was initiated in a split plot design with three main and three sub-treatments using maize (Kanchan-510) as the test crop. The main experimental treatments were: T1: Conventional Tillage (CT) +Two Intercultures (Two IC), T2: Low Tillage (LT) +Two Intercultures (Two IC) and T3: Low Tillage (LT) + Weedicide + One Interculture (One IC). The three sub treatments were, T1: 100% N through organic sources (compost), T2: 50% N through organic sources + 50% N through inorganic sources and T3: 100% N through inorganic sources. The results of the present study clearly revealed that the tillage treatments did not significantly influence most of the soil quality parameters except available S, microbial biomass carbon (MBC) and Mean weight Diameter of Soil Aggregates (MWD). When averaged over nutrient levels, among the tillage practices, conventional tillage + Two IC recorded the highest available S of 20.87 kg ha-1. However, sub-sub treatments viz nutrient management significantly influenced the organic carbon (OC), available N, P S and boron, dehyrogenase assay (DHA), labile carbon (LC), bulk density (BD) and MWD. When averaged over tillage levels, the application of nutrients through inorganic sources recorded significantly highest available N (160.50 kg ha-1), P (30.67 kg ha-1) and K (207.87 kg ha-1 in soil. Finally, in terms of Relative Soil Quality Indices (RSQI), Low tillage + Two IC (0.87) and Low tillage + Weedicide + One IC (0.89) proved superior compared to Conventional Tillage + 2 IC (0.82). Similarly, when averaged over tillage levels, the order of performance of nutrient management treatments was:100% N through organic sources (0.93) > 50% N through organic sources + 50 % N through inorganic sources (0.84) > 100% N through inorganic sources (0.82). Though the interactions between tillage levels and nutrient management were not significant, but the combination of Low tillage practices with 100 % organic Source of nutrients was quite superior in maintaining relatively higher RSQI. Thus, the results of the present study and methodology used will be highly useful to different stake holders associated withland and soil quality management

The Impact

Awareness to wards soil health and food quality has forced to find out a suitable and eco-friendly nutrient management system of crop production. Integrated nutrient management system found suitable on yield of cereal crops, but has least impact on leguminous crops. To study the impact of nutrient management practices and tillage practices was studied at the farm of Department of Soil Science, CSKHPKV, Palampur during 2013-16 gram-maize cropping sequence. The organic management with conventional tillage was found to be significantly superior with rest of the treatment combinations on yield attributes, symbiotic parameters and yield of gram in all the three years. The major constraints to grow gram at Palampur was the attack of root rot disease. The disease incidence was reduced through organic nutrient management with conventional tillage. The yield attributes and yield of maize was better in integrated management in organic management in second year. The conventional tillage in both the years registered significant impact on yield and yield attributes of maize.

The soil of the experimental field was sandy clay loam in texture with moderately alkaline pH, low in available nitrogen, medium in available P and high in available K. The field experiment was laid out in split plot design with (five tillage practices) in main plots and (three weed management practices) in sub plots. The results revealed that highest total nitrogen uptake was recorded with conventional tillage (Transplanted rice) – zero tillage (maize) and it is on par with conventional tillage (transplanted rice) – conventional tillage (maize) treatments. The highest total phosphorus and total potassium uptake was recorded with conventional tillage (transplanted) – conventional tillage (maize) and it was on par with conventional tillage (Transplanted) – zero tillage (maize). Integrated weed management was found to be significantly superior with nutrient uptake followed by chemical weed management.

<p>Improved fallows of <em>Sesbania sesban</em> (Sesbania) have been known to improve soil physical and chemical properties and increase crop yield compared to traditional fallows. However, the effects of soil tillage practices after improved fallows on soil properties, weeds, labour and subsequent maize crop have not been assessed in Southern Africa. This study aimed to evaluate how tillage practices affect yield of maize and affect soil properties after two years of fallow and subsequent cropping phase. In this study, done at sites in eastern Zambia, maize yield from a two-year planted Sesbania, natural fallow, continuously fertilized and unfertilized maize were compared under conventional, flat till and zero tillage practices. A split plot experiment, with improved fallow systems in the main plot and the tillage practice in the subplot, was established at the sites. The results showed that the increases in grain yield under conventional tillage over zero tillage practice were 17.8% and 28.2% during 2000/2001 and 2001/2002 seasons, respectively, at Msekera. At Chadiza, the increases in grain yield under conventional tillage over zero tillage were 66.3% and 327.4% during 2000/2001 and 2001/2002 seasons, respectively. Greater maize yields were achieved under Sesbania planted fallows compared to the natural fallow and maize monoculture without fertilizer. Overall, zero tillage practice resulted in lower maize grain yield, higher bulk density, reduced water intake, higher weed infestation and high labour demand during weeding compared to conventional tillage.</p>
