An experiment was conducted during 2012-13 and 2013-14 at Ludhiana, Punjab to find out the productivity and profitability of the cotton-wheat cropping system as influenced by complex fertilizers. The experiment was comprised of nine fertilizer treatments. The results demonstrated that significantly higher cotton yield and stalk yield was recorded under T9 -AP60+S15+Zn1.5 (15.3 q/ha and 50.5 q/ha respectively in 2012 and 22.2 q/ha and 55.6 respectively in 2013) which was statistically at par with T6 – DAP (P60)+S15+Zn1.5 (15.0 q/ ha and 50.4 q/ha respectively in 2012 and 22.1 q/ha and 55.4 q/ha, respectively in 2013). Similarly in wheat crop, T9 -AP60+S15+Zn1.5 gave significantly higher grain yield and straw yield (39.0 q/ha and 63.0 q/ha, respectively in 2012-13 and 45.6 q/ha and 73.6, respectively in 2013-14) which was comparable with T6 – DAP (P60)+S15+Zn1.5 (38.5 q/ ha and 62.8 q/ha respectively in 2012-13 and 44.4 q/ha and 72.4 q/ha in 2013-14)  as compare to other treatments. Economic analysis indicated higher net return (₹ 8739.0) and B:C ratio (0.37) for cotton under T8- AP30+S7.5+Zn0.75 whereas T9 -AP60+S15+Zn1.5 net return (₹14417.5) and B:C ratio (1.07) for wheat as compare with other treatments.

A field experiment was conducted during Rabi 2015-16, 2016-17 and 2017-18 by Krishi Vigyan Kendra Muktsar, to find out the performance of happy seeder machine for sowing of wheat after rice crop. Happy seeder tackles the problem of paddy straw which can convert this waste into resource. In the area, farmers generally burn rice residues because they felt that it interferes with tillage and seeding operations for the succeeding crops and it has no much economical use. The average grain yield revealed that happy seeder sown crop gave 47.5 q/ha grain yield as compared to 49.6 q/ha in conventional sown method. Net return was calculated during all the years. Happy seeder sown crop gave higher net return (Rs 55279.2/ha) from conventional method (Rs. 52189.7/ha). Net return was higher due to less cost of cultivation (Rs. 22325/ha) from Rs 28641.6/ha under conventional sowing method. So with Happy seeder, low cost of production with respect to conventional tillage system gave maximum net return and it is a cost effective technology. The cost of cultivation in happy seeder was also lesser than conventional method mainly due to less cost on tillage preparation, saving in weedicides, fertilizers etc. Farmers are more interested in variable costs and economic return of newly introduced enterprises. Economic analysis assists researches to plan their research for detailed investigation and to make decision, so that it may be recommended to the farmers. So, economic analysis is essential to check the profitability and net return of the system.

Nitrification and urease inhibitors have been used to reduce nitrous oxide (N2O) emissions and increase nitrogen use efficiency in many agricultural systems. However, their agronomic benefits, such as the improvement of grain yield, is uncertain. A two-year field experiment was conducted to (1) investigate whether the use of 3,4-dimethylpyrazole phosphate (DMPP) or N-(n-butyl) thiophosphoric triamide (NBPT) can reduce N2O emissions and increase grain yield and (2) explore the financial benefit of using DMPP or NBPT in a rain-fed cropping system in south-eastern Australia. The experiment was conducted at Wagga Wagga, New South Wales, Australia with wheat (Triticum aestivum L.) in 2012 and canola (Brassica napus L.) in 2013. Results showed that urea coated with DMPP reduced the cumulative N2O emission by 34% for a wheat crop in 2012 (P < 0.05) and by 62% for a canola crop in 2013 (P < 0.05) compared with normal urea, but urea coated NBPT had no effect on N2O emission for the wheat crop in 2012. Neither nitrification nor urease inhibitors increased crop yields because the low rainfall experienced led to little potential for gross N loss through denitrification, leaching or volatilisation pathways. In such dry years, only government or other financial incentives for N2O mitigation would make the use of DMPP with applied N economically viable.

The effects of varying durations of lucerne ley and subsequent wheat cropping on the moisture status of contrasting wheat growing soils are reported from two experiments in northern New South Wales. Lucerne leys of 5 1/2, 3 1/2 and 1 1/2 years on a red brown earth and 3 1/2, 2 1/2, and 1 1/2 years on a black earth were compared with a wheat-cowpea rotation, long fallow and continuous wheat. Lucerne extracted available soil water within eight months of sowing to a depth of 100 cm, with partial extraction of water to 150 cm. Within 18 months available water to a depth of 200 cm had been extracted. Subsequent growth of lucerne was dependent on incident rainfall and water extraction from depths greater than 200 cm. Wheat extracted water from the soil only to a depth of 150 cm, and extracted less water to this depth than did lucerne. Lucerne extracted water beyond the -1 5 bar suction level. On the black earth, soil moisture at 150 cm had not been recharged before time for sowing the third wheat crop, 28 months after lucerne plough-out. On the red brown earth, after a drought enforced long fallow immediately following lucerne plough-out, soil water at 200 cm was recharged within 18 months. Available soil moisture after three to five months fallow following plough-out of the lucerne leys was much less than for a wheat cropping system, with a consequent severe reduction in the grain yield of the following wheat crop. On the black earth grain yield was reduced by 7.7 kg ha-1 for each reduction of 1 mm in available moisture in the first crop after lucerne plough-out. Data indicate that lucerne must be ploughed out before January if a severe reduction in yield of the following wheat crop is to be minimized.

Aims: To investigate the direct and residual effect of boron application on yield and nutrient content under rice-wheat cropping system in middle Gangatic alluvial plan. Study Design: Completely random design (CRD). Place and Duration of Study: Net-house of the Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, India during 2017-18. Methodology: The pot experiment was comprised with ten treatments among them eight for boron (ranges from 0.5 to 4.0 mg B kg-1) along with control and recommended dose of fertilizer (RDF). Rice (Oryza sativa L.) variety ARIZE 6444 was used as test crop and after harvesting of rice crop, wheat (Triticum aestivum L.) variety HUW 468 was grown in the same pot without fresh application B. The yield data was recorded after harvesting of rice and wheat. The nutrient content in grain and straw and post-harvest soil properties were analyzed using standard protocol. Results: The maximum grain yield in rice (44.07 g pot-1) was recorded in T5 (RDF + 1.5 kg B ha-1), whereas in wheat (19.70 g pot-1) was observed in T8 (RDF + 3 kg B ha-1). The maximum straw yield in rice (24.35 g pot-1) was recorded in T5 (RDF+ 1.5 kg B ka-1), whereas in wheat (48.65 g pot-1) was in T8 (RDF + 3 kg B ha-1). Application of RDF along with 1.5 kg B ha-1 was recorded the maximum (48.99%) harvest index in rice, whereas its (B) residual effect in wheat crop was maximum in RDF + 2 kg B ha-1. Application of B @ 1.5 kg B ha-1 significantly enhanced the Fe, Cu, Mn and Zn content in rice grain, whereas residual effect of 3 kg ha-1 B application has significantly improved the Fe, Cu and Mn content in wheat grain. Conclusion: It was found that application of B did not increased grain yield of rice and wheat significantly over RDF. A significant residual effect of B application in rice was noticed even after the harvest of wheat crop particularly at highest doses of B application.

Tegra practice (healthy seedling, mechanical transplanting, herbicide application and advisory services), as a new concept in commercial rice cultivation, needs to be evaluated with farmer’s practices in our country. This study was conducted in the farmers’ field during Aman 2013 and Boro 2013-14 seasons in Bogra district. In each season, six farmers within one kilometer radius were selected to conduct this study. Randomized complete block design (RCBD) with two treatments namely farmer’s practices (FP) and Tegra practices (TP) were used in the experiment. Self-propelled four rows walking-type rice transplanter was used to transplant seedling in TP. Seedlings were raised in plastic tray to use in mechanical transplanter. The mat seedlings were ready to transplant when attained 3-4 leaves and 10-12 cm height. Mechanical transplanting found faster than manual transplanting. Missing/floating hill observed insignificant in mechanically transplanted field. Fuel consumption of mechanical transplanter obtained 4.5 L/ha. Tender aged seedling was used in TP and seedling age was higher in FP than TP. Plant height followed the similar trend in both the practices. Tillering ability obtained the highest in TP than FP. TP produced significantly higher (14-23%) grain yield in both seasons. The total cost of production, gross return, gross margin and BCR obtained the highest in TP. BCR showed 5-13% higher in TP than FP in both the seasons due to higher grain and straw yield. The economic analysis clearly revealed the profitability of TP over FP in both the seasons.Bangladesh Rice j. 2016, 20(1): 33-43

Field experiment was conducted during Rabi seasons of 2010-11, 2011-12 and 2012-13 at Research and Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur to examine and study the phenology, accumulation of growing degree days (GDD), heliothermal units (HTU), photothermal unit (PTU) and performance of wheat (Triticum aestivam L.) of four wheat varieties grown under five different sowing dates in factorial Randomized Block Design. It was observed that GDDs got reduced significantly with subsequent delay in sowing time. For our study purpose and as per package of practices, 25 November D1 can be taken as early sowing and D2 - 5 December as timely sowing conditions.  The wheat varieties Amar and Sujata took highest GDD, HTU and PTU to maturity.  On the mean basis the variety Kanchan produced highest grain yield (3147 kg/ha) followed by GW-273 (2947 kg/ha).  The significant reduction in grain yield was recorded when sowing was delayed beyond D2 - December 05.  Among the wheat varieties Kanchan showed better performance in terms of RUE followed by GW-273 and Sujata. Highest HUE was observed in wheat variety Kanchan followed by Sujata and GW-273. Varieties giving higher yield, RUE and HUE are identified under varying growing environments so as to suggest the appropriate sowing dates of wheat varieties in Chhattisgarh plains. GDD is giving consistent results as its variability is least varying between 3.4-5.3 per cent for different varieties and therefore it is reliable index for studying environmental effects on wheat in this region. Lowest RUE was observed under 5 January sowing (D5) in the all varieties which leads to conclusion that this sowing date must be avoided and wheat crop sowing must be completed latest by 25 December to avoid adverse effects on productivity.

A field experiment was conducted to determine the effect of cultivation and plant residue incorporation of blackgram [Vigna mungo (L.) Hepper], mungbean [Vigna radiata (L.) Wilczek], cowpea (Vigna sinensis L.), maize (Zea mays L.) and maize+blackgram on response of rice to two levels (0 and 90 kg ha-1) of nitrogen and their residual effects on nitrogen management of subsequent wheat crop. The experiment was carried out in Randomized Complete Block design in spring, Split Plot design in rainy, and Split-Split plot design in winter seasons of 2000 at Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, Nepal. Results showed that cultivation and incorporation of different spring season crop’s (legume and cereal) residue into the soil did not significantly affect rice yield. Such trend was also observed on wheat grain yield when spring season crops were followed by rice in a sequential cropping system. Significantly higher (p<0.001) rice equivalent yield (6.56 t ha-1) and net profit (Rs. 46489 ha-1) were obtained under mungbean-rice sequence. Similarly, significantly higher (p<0.001) wheat equivalent yield (8.74 t ha-1) and net profit (Rs. 44811 ha-1) were obtained under mungbean-rice-wheat sequence. Significantly higher yield of rice was obtained under 90 kg N ha-1 compared to control and had significant residual effect of N on wheat grain yield. Nitrogen topdressed at crown root initiation (CRI) and panicle initiation (PI) stages did not influence significantly on the grain yield of wheat. Therefore, for the long term sustainability of rice-wheat cropping system, inclusion of mungbean in the spring (fallow) season could be considered promising practice.

The results on the effect of three decade long term application of chemical fertilizers and amendments on the yield of continuous maize-wheat crop rotation in an acid alfisol at Palampur revealed that continuous omission of essential nutrients in a maize-wheat sequence resulted in an appreciable decline in the grain yield of maize and wheat crops. A remarkable reduction in crop yield was noticed in plots where nitrogen was applied alone. Use of recommended level of N alone through urea had deleterious effect on crop productivity. The continuous exhaustionof native pools of K in 100% NP treated plots appreciably reduced percent grain yield. Application of farmyard manure (FYM) and lime along with NPK fertilizers increased the crop yield. The integrated use of optimal dose of NPK and FYM give better and more sustainable yields.

Field experiments/On Farm trial (OFT) were conducted at Farmers field of village, Halsi, Lakhisarai under the supervision of ICAR-Krishi Vigyan Kendra, BAU, Bihar, India in 2012-13 and 2013-14.To established a uniform plant stand for the maximum yield and net return ultimately for the drudgery reduction. The experimental trial was laid out in a Randomized block design replicated four times (Number of Farmers) with six treatments comprises of transplanted rice (Farmers practices), system of rice intensification (SRI) square transplanted, DSR- Zero-tillage (dry seeding), direct seeded rice (DSR)- broadcasting (dry seeding), DSR- Drum seeded (dry seeding) and DSR- wet seeded (sprouted seeding). Among the different establishment method, SRI planting significantly influenced the growth, yield attributing characters and yield, but relatively was on par with transplanted rice. The maximum plant height, number of tillers m-2, panicle length, leaf area Index (LAI) , number of filled grains panicle-1, number of unfilled grain panicle-1,test weight, grain yield (5712 kg ha-1), straw yield (7950kg ha-1) and net return (Rs. 50,409.30 ha-1) were recorded under SRI (square transplanted) but which were on par with transplanted rice and DSR- Zero-tillage while benefit cost ratio were significantly highest (2.56) under DSR- Zero-tillage. Lowest grain yield, straw yield and gross return were observed under DSR- broadcasting and lowest net return were recorded under DSR- wet planted (sprouted seeds) and lowest B:C ratio were found under Transplanted rice. System of rice intensification (SRI) having higher yield followed by puddled transplanted rice, DSR- drum seeder (sprouted seed) and DSR- zero-tillage. DSR- zero-tillage is a viable, long-lasting and appropriate substitute to puddled transplanted rice and to be the most profitable methods with minimize the cost of cultivation.
