A field experiment was conducted to study the effect of tillage, mulching and weed management practices on growth, yield and uptake of nutrients by chickpea during rabi 2010 and 2011 at MARS, UAS Dharwad, Karnataka. Conventional tillage increased various growth, yield parameters and chickpea yield and also nutrient uptake and nitrogen use efficiency over minimum and zero tillage practices. Significantly higher gross return, net return and B:C ratio were recorded in conventional tillage as compared to minimum and zero tillage practices. Mulching practice showed higher growth, yield and yield parameters of chickpea and also nutrient uptake and economics over minimum and zero tillage practices. Significantly higher growth, chickpea yield and yield parameters, nutrient uptake, gross return, net return and B:C ratio were recorded in application of pendimethalin as compared to other weed management practices.

A field study was conducted during rabi seasons of 2010-11 and 2011-12 at the Research cum Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh to evaluate the effect of various tillage and weed management techniques on energy dynamics and profitability of chickpea-rice cropping sequence in irrigated ecosystem of C.G. plains. The results indicate that plots were divided into main and sub plots (tillage and weed management practices). Three tillage practices viz., conventional tillage (T1),  minimum tillage (T2) and zero tillage (T3) in main plot and nine weed management practices as pendimethalin @ 1000 g ha-1 PE (W1), imazethapyr @ 80 g ha-1 PE (W2), imazethapyr @ 90 g ha-1 PE (W3), imazethapyr @ 100 g ha-1 PE (W4) at 2 DAS, imazethapyr @ 70 g ha-1 POE (W5), imazethapyr @ 80 g ha-1 POE (W6), imazethapyr @ 90 g ha-1 POE (W7) at 20 DAS, one hand weeding at 20 DAS (W8) and weedy check (W9), in sub plots. Among the various tillage practices, maximum energy use efficiency 3.74 q MJ-1 × 10-3 ha-1 and energy productivity 160.34 kg MJ-1 ha-1 were obtained with conventional tillage (T1) followed by minimum tillage (T2) and zero tillage (T3) and among the different weed control methods, maximum energy use efficiency 5.46 q MJ-1 × 10-3 ha-1 and energy productivity 233.37 kg MJ-1 ha-1 were found with one hand weeding at 20 DAS (W8) followed by post-emergence application of imazethapyr @ 90 g ha-1 (W7) followed by imazethapyr @ 80 g ha-1 PoE (W6). The economic production of experiment in terms of net return was maximum under (T1) conventional tillage Rs.19824.21 ha-1 with B:C ratio 1.19 and (W8) one hand weeding at 20 DAS Rs.19171.44 ha-1 with B:C ratio 0.95 and this was followed by @ 90 g ha-1 imazethapyr, where net return Rs.19086.74 ha-1 and B:C ratio 1.04. The minimum net return and B:C ratio was observed under zero tillage (T3) and weedy check (W9).

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 entitled ‘Influence of tillage and weed management practices on yield and nutrient uptake of maize’ was conducted during Rabi-2018 at all India coordinated research project on Weed Management, College of Agriculture, Rajendranagar, Professor Jayashankar Telangana State Agricultural University, Hyderabad to study the effect of different tillage and weed management practices on nutrient uptake 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.

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.

A field experiment was conducted at the Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology Pantnagar, Udham Singh Nagar during continuous two years to study the weed flora, yield and nutrient uptake of wheat (Triticum aestivum L.) under different wheat establishment methods in main plots and seven weed management in sub plots. Phalaris minor was the most dominant weed at 60 DAS contributed 55.0 per cent of total weed population. Melilotusindica was the major non grassy weeds in wheat which contributed 11 per cent to total weed population during respective years. Sowing of wheat with zero tillage significantly reduced the Phalaris minor density as compared to conventionally tilled wheat after transplanted rice, 60 per cent Phalaris minor emerged from 0-3 cm in reduced and conventional tillage where as in zero tillage after transplanted rice there was 55 per cent emergence from 0-3 cm layer.The highest grain yield was obtained in two hand weedings done at 30 and 60 DAS and was at par with Isoproturon 1.0 kg ha-1 + Metsulfuron methyl 4 g ha-1 at 30 DAS and Clodinafop – Propargyl 60 g ha-1 at 30 DAS fb. Metsulfuron methyl 4 g ha-1 at 37 DAS. Zero tillage resulted in significantly higher uptake of NPK by wheat plants as compared to conventional tillage, whereas reduced tillage recorded minimum NPK, which was significantly lower over the other treatments of wheat establishment methods.

Abstract The research work was conducted to see the effect of organic mulches and tillage practices on growth, yield and quality of autumn planted maize and soil physical properties. Four types of tillage practices i.e. conventional tillage, zero tillage, bar harrow tillage, subsoiler tillage and two types of mulching material i.e. wheat straw mulch and saw dust mulch was used. The mulching material was partially incorporated in the field after germination of crop. The experiment was carried out in randomized complete block design (RCBD) with three replications. Control treatment was kept for comparison. All other practices were kept uniform throughout the crop period. Data about growth and yield components were collected and analyzed statistically by fisher analysis of variance and treatment significance was measured by significant difference test at 5v% level. The results showed that zero tillage + wheat straw mulch gave maximum 1000-grain weight (341.67 g) and grain yield (6.33 t ha-1) and it was followed by conventional tillage + saw dust mulch (4.92 t ha-1). Higher protein content was recorded in Subsoiler tillage (10.26 %). Conducive soil physical conditions were observed in the zero tillage practices over the other tillage practices. On the basis of these results it could be proposed that the tillage and mulching is a very important practice to increase the yield of crop. Among different practices, zero tillage with wheat straw mulching gave maximum yield and net benefits.

Declining productivity of rice-wheat system in Indo–Gangetic Plains poses risk to conventional practices because of high production cost and low input use efficiency. Four crop establishment methods (CEM) and four weed management practices (WMP) were compared in a 2–year study to determine the productivity and profitability of rice-wheat system. Growth, yield traits and yields of rice was uninfluenced by CEM. Zero tillage rice (ZTR)–zero tillage wheat (ZTW) exhibited highest improvement in mean wheat yield, system productivity and profitability by 7.5%, 4.0% and 16.0%, respectively over conventional tillage rice (CTR)–conventional tillage wheat (CTW). CTR–ZTW recorded minimum total weed density and biomass in system. Post emergence application of bispyribac 25 g ha-1 + azimsulfuron 35 g ha-1 (bis + azim) in rice at 20 days after sowing (DAS)/days after transplanting (DAT); clodinofop 60 g ha-1 + carfentrazone 20 g ha-1 (clod + carf) in wheat at 30–35 DAS minimized total weed density and biomass, increased growth, productivity and profitability of the system. Results suggest that higher growth, productivity and profitability of rice–wheat system may be achieved by adoption of ZTR–ZTW with application of bis + azim in rice and clod + carf in wheat.

Tillage System

ABSTRACT: Weeds cause considerable damage to rice crop. To ascertain the influence of different weed management practices under different tillage systems, a field experiment was conducted during 2014-15. Experimental design was RCB with split-plot arrangement and with a net plot size of 6 x 2 m. Three tillage systems viz; zero tillage with glyphosate application and conventional tillage with and without stale seed bed, and seven weed management treatments viz; weedy check, manual weeding, oxadiargyl as pre-emergence, pyrazosulfuron as pre-emergence, pyrazosulfuron as post-emergence, fenoxaprop-ethyle + sodium fluoride as post-emergence and fenoxaprop-ethyle + sodium fluoride as post-emergence. Results revealed that all treatments including tillage systems and herbicides significantly (p<0.05) affected weed density and weed dry biomass. Minimum weed density (229.22, 159.22 and 127.77 m-2) and weed dry biomass (68.01, 49.29 and 41.08 g m-2) at 30, 45 and 60 DAS (days after sowing) were recorded for pyrazosulfuron (as pre-emergence), respectively, followed by fenoxaprop-ethyle + sodium fluoride (as post-emergence). Maximum 1000-kernel weight and kernel yield (19.15 g and 3.45 ton ha-1) were recorded for weed free treatments and it was 12 and 57% higher than weedy check. Maximum net benefit and benefit to cost ratio (USD$ 817 ha-1 and 1.76, respectively) were recorded for pyrazosulfuron applied at either pre- or post-emergence stage under zero tillage system. Conclusively, pyrazosulfuron (as pre-emergence) and fenoxaprop-ethyle + sodium fluoride (as post-emergence) gave the best weed control under conventional tillage with stale seed bed system, while pyrazosulfuron exhibited maximum benefit-cost ratio under zero tillage system.

A field experiment was carried out during summer 2019 and 2020 at Zonal Agricultural and Horticultural Research Station, Hiriyur University of Agricultural and Horticultural Sciences, Shivamogga to study the influence of natural farming practices on growth, yield attributes and yield of ground nut in black soils. Pooled analysis of two years revealed that recommended dose of fertilizer significantly recorded higher pod (1969 kg ha-1), kernel (1516 kg ha-1) and haulm (3699 kg ha-1) yield as compared to other nutrient management practices. Similar trend was noticed in other yield parameters. Significantly higher nutrient uptake was observed in treatment receiving recommended package of practice i.e., nitrogen (101.75 kg ha-1), phosphorus (28.41 kg ha-1) and potassium (94.54 kg ha-1), respectively. However, the natural farming treatment receiving significantly recorded higher gross returns (Rs. 1,62,458 ha-1), net returns (Rs.1,14,063) and B:C ratio (3.36) as compared to other nutrient management practices. In 2019 and 2020 the same treatment recorded significantly higher growth, yield parameters and economics.
