Effect of Nutrient and Spacing on Growth and Biomass Production in Poplar under Nursery Condition

Nutrient management is one of the prime factors which play a pivotal role on the growth, development and successful completion of life cycle in all green plants. It is very essential to establish alternate and fast growing tree species to meet the raw material demand of various wood based industries. Poplar occupies an important place amongst fast growing species due to their multiple uses as an industrial raw material in pulp and paper. In this study, effect of different spacing (60×60 cm, 70×30 cm and 80×30 cm) and fertilizer levels (N1= N0 P0 K0 (Control), N2= N100 P50 K25, N3= N150 P75 K37.5, N4= N200 P100 K50, N5= N250 P75 K62.5 and N6= N0 P0 K0 + Biofertilizers) on growth of poplar under nursery condition during 2019 and 2020. The performances of growth were influenced by N, P and K at different levels. All the growth characters viz. sprouting per cent, basal diameter, leaf area and total biomass in general increased significantly with increased spacing during both the experimental years. However, plant height and chlorophyll content showed differential response and increased significantly with decrease in spacing. Fertilizer application significantly improved the growth of poplar clones in terms of basal diameter, plant height, leaf area, chlorophyll content and total biomass over control. The performances of growth were influenced by N, P and K at different levels during 2019 and 2020 in poplar nursery were found significantly higher in N200P100K50  and the lowest in control among all the other nutrients levels.  In poplar nursery, the growth was significantly higher for 60 × 60 cm spacing as compared to other spacings of poplar. The highest growth in poplar was registered under the application of N200 P100 K50 with 60×60 cm spacing

The experiment was laid out in a randomized block design with eight treatment combinations, i.e. ICM modules (ICM1 to ICM8). The study indicated that the yield attributes, grain yield (4.03 t/ha), harvest index, as well as gross ( 96,253/ha) and net ( 50,693/ha) returns as well as gross B: C ratio (2.11) of rice crop were significantly higher in the ICM7, i.e. zero till (ZT)-summer mungbean residue retention (SMB-RR) + ZT- direct seeded rice (DSR) + wheat residue @ 3 t/ha + 75% of recommended dose of fertilizers @ 100 : 50 : 50 kg N : P2 O5 : K2 O/ha (RDF) (N through Zn coated urea/ZCU) + glyphosate as pre-plant (PP) @ 1 kg a.i./ha + pretilachlor as pre-emergence (PE)@ 0.75 kg a.i./ha followed by bispyribac-sodium @ 25 g a.i./ha as post emergence (POE) at 25 days after sowing(DAS) + need based water management, disease and integrated pest management, with comparison to othermodules. The escalation of cost due to transplanting was increased 5,045/ha compared to direct–seeded rice.The increase in net returns with ICM7 was 36.7, 41.4 and 9.3% over ICM1, conventional transplanting/TPR + 100% of RDF + butachlor-PE @ 1 kg a. i./ha + 1 hand-weeding (HW); ICM6 , ZT-DSR + wheat residue @ 3 t/ha + 75% RDF + AMF + NPK-biofertilizer + glyphosate as PP @ 1 kg a.i./ha + pretilachlor-PE @ 0.75 kg a.i./ha followed by bispyribac-sodium @ 25 g a.i./ha as POE at 25 DAS + 1 HW and ICM8 , ZT-SMB-RR + ZT- DSR + wheat residue @ 3 t/ha + 50% RDF + AMF + NPK-bf + glyphosate as PP @ 1 kg a.i./ha + pretilachlor-PE @ 0.75 kg a.i./ha followed by bispyribac-sodium @ 25 g a.i./ha as POE at 25 DAS + 1 HW, respectively. Hence, the superior ICMmodule, i.e. ICM7 may be useful for improving profitability and B : C ratio of direct-seeded rice with respect to other modules.Not Availabl

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
