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.

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.

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.

Background: Agriculture and its allied sectors is an important sector in employment, income and food security. The increasing demands for food grains and cash crops, the area under fodder crops has been static since last 3-4 decades (8.4 mha) resulted into a net deficit in dry and green fodder is around 10 and 35%, respectively making livestock rearing more challenging. Conventional agriculture has largelybeen characterized by conventional tillage which caused soil degradation and negative impacts on soil physical and biological activity. To mitigate these negative effects, resource conservation technologies (RCTs) was tested and adopted to save substantial quantity of irrigation water, reducing the cost of cultivation, timely sowing, improve input use efficiency and left indirect effect on mitigating the adverse effect of climate changes. Biological N2 fixation (BNF) can make plants self-sustaining for N nutrition and avoiding the need for mineral N fertilization. The current study aimed enhancing fodder production by adoption of modern tillage practices and efficient N management. Methods: In this field-laboratory investigation during 2017-18, experiment was laid out in the split plot design consisting of three tillage practices zero tillage (ZT), conventional tillage (CT) and raised bed (RB) and six N management viz., N0, N75, N75+Rhizo, N100, N100+Rhizo and N125%. The soil of the experimental field was clay loam in texture having pH 7.30, EC; 0.35 dS/m, medium in organic carbon (0.63%), low in nitrogen (188.48 kg/ha), medium in phosphorus (23.56 kg/ha) and potassium (271.12 kg/ha). The recommended dose of fertilizer and other cultural practices was applied as per treatments with standard process. The crop was harvested at 60 days after sowing and weighed for green fodder yield. The observations growth, yields and quality parameters was recorded as per the standard method. Statistical analysis was done using analysis of variance in split plot design. Result: ZT practices significantly improved growth attributes, fodder yield and available nitrogen. Higher fodder yield of cowpea was recorded with ZT as compared to CT and it was statistically similar in RB. The nitrogen management practices had significant effect on root length and root nodules, plant growth attributes, fodder yield and available N, P and K. The significant fodder yield was increase with successive increase of N application up to 75% N + rhizobium, over 0 and 75% N alone. The present work shows that adoption of ZT and inoculation of rhizobia had significantly improved soil health and stabilized fodder yield of cowpea besides decrease fertilizer nitrogen requirement in the irrigated agro-ecosystem of T-IGP.

A field experiment was conducted during rabi seasons of 2007-08 and 2008-09 on mollisols at G.B. Pant University of Agriculture & Technology, Pantnagar to study the performance of fieldpea (Pisum sativum L.var arvense) under different planting methods, irrigation levels and weed management practices. Results revealed that growth attributes as plant height, number of branches and dry matter accumulation per plant, number and dry weight of nodules per plant, density and dry matter of weeds/unit area, nutrient uptake and yield attributes as pods/plant, 1000-grain weight, grain yield/plant and grain yield of fieldpea were significantly higher under raised bed planting as compared to flat bed. Planting on raised bed increased grain yield of fieldpea by 17.5% over flat bed. Two irrigations applied at critical stages i.e. pre-flowering and pod formation proved promising in increasing the growth, nutrient uptake, yield attributes and grain yield of pea. One hand weeding done at 25 days after sowing (DAS) reduced the density and dry matter of weeds significantly and one hand weeding done at 25 DAS increased the values of growth attributes, number and dry weight of nodules, nutrient uptake, yield attributes and grain yield as compared to pendimethalin 1.0 kg a.i./ha applied as pre-emergence and weedy check.

The Cost

Rice-wheat production is an essential component of cropping systems in the Indus-Ganga Plains (IGP) which play a pivotal role in food security of south Asia. These crops are being cultivated on an area of about 13.5 M ha of South Asia. In rice-wheat cropping system, the major reason for lower wheat grain yield is use of unwise tillage practices during wheat seedbed preparation, cultivation of late maturing rice varieties, water shortage, labor shortage, high cost of fertilizers and poor crop management practices. Resource-conserving technology improves the sustainability and productivity of wheat, which ultimately increase the farmer’s livelihood and reduce poverty. Tillage plays an important role in agricultural operation for soil manipulation to optimize the crop productivity. Different tillage systems are being practiced for wheat production in rice-wheat cropping systems including intensive tillage system, conventional and deep tillage, conservation tillage that consisting of minimum tillage, ridge tillage, and no-till or zero tillage system. Zero tillage gives more accessible and efficient planting system that ensures timely wheat cultivation, cut off the tillage operation, better crop residue management that ultimately minimize the cost of production and keeps environment clean. Operational costs for wheat sowing are 50-60% lower with zero tillage (ZT) sowing than with conventional sowing. The cost saving effect is the main reason for the spread of zero tillage technology in rice-wheat system. Current paper presented a review of different tillage systems and their effects on soil physical properties, plant available water, soil organic matter and nutrients, rice residues, wheat yield and farmer’s economics.

The temporal and spatial intensity of rainfall in north-east plains (Central and Eastern Uttar Pradesh, Bihar, Jharkhand, West Bengal, Assom and North-Eastern states) often leads to temporary waterlogging, causing partial to complete mortality of pigeonpea seedlings during rainy season. Post-rainy season (September) plantings may be adopted as an alternate approach to address the issue of waterlogging and crop diversification. Research conducted at the ICAR-RCER, Patna has shown that sowing of ‘Pusa 9’ during second week of September after harvest of quality protein green cob maize provided up to 3.0 t/ha grain yield under zero tillage with optimum crop management practices (one hand weeding, one-two insecticide spray of imidacloroprid @1mL/L water at 10 days’ interval commencing from second fortnight of February). Similarly, ‘IPA 203’ sown on September 20, 2018 yielded more than 3.0 t/ha under conventional tillage practices (N: P: K: 20:50:0; two hand weeding; one irrigation during second fortnight of December and two spray of the same insecticide at the same interval). These findings indicate that the system is agronomically feasible, economically highly remunerative and ecologically sustainable to bring about diversification in upland ecology of north-east plains of India.

Aim: Comparative evaluation of weed management practices and fertilizer levels on crop nutrient uptake and weed nutrient removal in the hybrid rice. Study Design: The experiment was laid out in split-plot design with weed management in main-plot and fertilizer levels in sub-plot and was replicated thrice. Place and Duration of Study: Experiment was performed during the kharif period of 2017 at the Research Farm, TCA, Dholi, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur (BIHAR). Methodology: The experiment was performed with twelve treatments in a split plot design. The main plot comprised four different weed management practices and under the sub-plot there were three fertilizer levels. Rice hybrid “ARIZE-6444” was taken as the test variety. Observations of the crop and weeds during the experimental duration were recorded at regular intervals, to assess the probable relationship between growth attributes and the final yield. The significance of the treatment impact was examined by the F test. Results: Among weed management practices, maximum uptake by rice with respect to nitrogen (152.85 Kg/ha), phosphorous (45.79 Kg/ha) and potassium (187.13 Kg/ha) and minimum removal by weed regarding nitrogen (1.30 Kg/ha), phosphorous (0.54 Kg/ha) and potassium (1.85 Kg/ha) was recorded in treatment hand weeding twice which was observed statistically at par with Bispyribac-sodium @ 25 g/ha + Pyrazosulfuron @ 25 g/ha at 25 DAT. Among fertilizer levels, application of 150 per cent RDF registered the highest portion of nitrogen (130.52 Kg/ha), phosphorous (40.40 Kg/ha) and potassium (164.49 Kg/ha) uptake by rice crop and nutrient removal through weeds is nitrogen (10.65 Kg/ha), phosphorous (4.84 Kg/ha) and potassium (15.59 Kg/ha) of, and respectively. Conclusion: Among different weed management practices combined application of Bispyribac-sodium @ 25 g/ha + Pyrazosulfuron @ 25 g/ha at @) DAT or hand weeding twice (20 and 40 DAT) was found effective in controlling weeds and increase in the quality and quantity of rice. Among fertilizer levels application of 125% RDF was found effective in increase in the yield, nutrient content of the crop and substantially reduction of nutrients removed by weed in rice field.
