The factorial R.B.D. comprised of two spacings (20 x 10cm and 30 x 10 cm) and five levels of phosphorus (0, 20, 30, 40 and 50 kg P2O5 ha-1) with three replications. Although wider spacing (30 cm x 10 cm) resulted in greater number of pods/plant (12.05) and seeds/pod (4.43) but higher grain yield (739 kg/ha) was recorded with closer spacing (20 cm x 10 cm) probably due to greater plant population in per unit area.

The experiment comprised of four doses of pyrazosulfuron-ethyl i.e. 0, 15, 25 and 35 g a.i.ha-1 and threecrop establishmentmethods i.e. broadcasting, drum seeding and transplanting method.The result revealed that among the different doses, pyrazosulfuron-ethyl @ 35g a.i.ha-1was most effectivein suppressing weeds, decreasing dry matter and highestweed control efficiency. Among the different establishment methods, transplanting was found to be the most effective method. It was also evident that the combined effect ofpyrazosulfuron-ethyl @ 35g a.i.ha-1along with transplanting method recorded significantly higher yield attributes and grain yield. However,pyrazosulfuron-ethyl @ 35g a.i.ha-1under drum seeding ...

The highest rice grain yield (35.83 q ha1), weed control efficiency (72.42%), harvest index and all the yield contributing characters were recorded in two hand weeded plot but was statistically at par with pyrazosulfuron-ethyl @ 30g a.i. ha-1 with one hand weeding. Transplanted rice outperformed the two direct seeded rice (sprouted and dry seeding) in all respect but was uneconomical. Maximum weed index (73.40) was observed under transplanted rice with unweeded check and least with pyrazosulfuron-ethyl fb hand weeding showing as low as 6.16 %. Economically, direct sowing (sprouted seed) with pyrazosulfuron-ethyl fb one hand weeding was proved to be the most viable combination which also conforms to the principle of integrated weed management.

Information literacy remains the least attended agenda and remains invisible to the academia world because it is misunderstood; misinterpreted and academic administrators have not put it on their institutions' agendas and still remain alien to many. There is also a false belief that information literacy is acquired only by experience and a false assumption that technological ability is the same as information literacy. Faculty on the other hand makes information literacy less significant than other educational pursuits and stereotyping the ability of librarians and the accrediting bodies have not yet advanced information literacy to a viable position in higher education. The new information age demands that these barriers be overcome and information literacy take a prominent place within the academic experience that will ultimately accelerate research productivity.

The pooled result revealed that application of 60kg P2O5/ha through single super phosphate (SSP), diammonium phosphate (DAP) and combination of SSP+MRP (Mussoorie rock phosphate) registered significantly higher dryrnatter production, number of branches and clusters. Increase in number of pods, podlength and number of seeds per pod as well as yield were also recorded in these treatments.

The physiological ageing of seed rhizome of turmeric was influenced by both temperature and relative humidity. Ageing was faster at higher temperature and less in relative humidity.10 kg of turmeric without mixing rice husk(T 1) showed significant loss in weight over the other treatments. The sprout length was found to be significantly higher in 10 kg of turmeric + 2.6 kg of rice husk(T 8)and 10 kg of turmeric + 2.4 kg of rice husk(T 7)than the rest of the treatments and the minimum in control (T 1). It was observed that shrinkage and change in colour of seed rhizomes were severe in the control as compared to other treatments. It also showed that well dried turmeric is not susceptible to any mould growth or disease problem.

India accounts for about 21% of the world‟s total rice production and holds the second position both in production and consumption of rice in the world next to China. Rice is an important crop of the state Manipur with low productivity. The state has 0.18 million ha under rice cultivation, which covers both irrigated and rainfed areas. The area has increased from 0.16 to 0.18 million ha during last seven years. Rice is mainly grown during the kharif season covering an area of 1,76,310 hectares, producing 435.93 thousand tonnes with an average productivity of 2413.52 kg/ha (Anon., 2005). Rapid water crisis, water-demanding nature of traditionally cultivated rice and increasing labour costs ramble the search for alternative management methods to increase water productivity, system sustainability and profitability. Direct seeded rice (DSR) technique is becoming popular nowadays becau...

Unchecked human activities such as over-expanded use of fossil fuels and deforestation have resulted in climate change which further worsens the present situation by impacting both crop and weed. Predicted alteration in atmospheric CO2, temperature and frequent extreme events (e.g., droughts and floods) owing to climate change will reduce crop yields by affecting plant growth as well as pest pressure (weed, insect pest and pathogens) and their invasiveness, thus threatening global food security. CO2 fertilization due to rising CO2 level will benefit C3 crops, thus reducing the competitive ability of most of troublesome weeds which are C4 plants. However, weeds are predicted to become more competitive over crops owing its wide genetic diversity, colonising ability and enhanced aggressively of C3 weeds consequently making weed management in field situations costlier and more difficult. Change in ...

Results revealed that, two hand weeding (HW) was the most effective method for weed control next to weed free. At 60 DAS however, lowest density and dry matter accumulation of all weed species were recorded with two hand weeding at 30 and 45 DAS followed by sequential/continuous application of Pendimethalin (PE) and Imazethapyr (post-emergence/POE) that remained statistically at par with Pendimethalin+MW in the case of BLWs and grasses and Chlorimuron ethyl+MW in respect of sedges. Maximum weed control efficiency (WCE) was achieved under two HW (83%) followed by Pendimethalin+MW at 45 DAS and continuous a...

Results indicated that bed planting of dry-seeded rice suppressed dry matter accumulation of weeds–grasses, sedges and broad leaf weeds most effectively among crop establishment methods, and as a consequence this crop establishment method had markedly higher growth rates, higher growth and yield attributes. Among different weed management practices, integrated weed management practices, namely, pre-emergence spray of pendimethalin 1 kg/ha followed by brown manuring of dhaincha by 2,4-D 0.50 kg/ha at 25 days after sowing (DAS) and combination of pre-emergence spray of pendimethalin 1 kg/ha followed by early post-emergence spray of bispyribac 0.025 kg/ha followed by brown manuring of dhaincha by 2,4-D 0.50 kg/ha at 25 DAS significantly lowered dry matter of all weeds than other weed management practices, thus improved growth and its rate and yield attributes of direct-seeded rice. Though crop establishment methods did not significantly influence grain yield of direct-seeded rice, protein content in grain and its yield were markedly improved by bed and no-till methods than conventional method. Integration of pendithalin application with brown manuring of dhaincha and pendimethalin followed by bispyribac followed by brown manuring of dhaincha registered significantly higher grain yield, protein content in grain and its yield than remaining weed management practices.

Bed and no-till planting were equally effective in reducing nutrient (NPK) depletion by weeds than conventional planting. However, there was no significant difference among them in terms of grain and straw yield. Also, bed and no-till planting increased total nutrient (NPK) uptake than conventional planting. No-till had highest partial factor productivity of nutrients. Brown manuring of dhaincha at 25 DAS by 2, 4-D 0.50 kg/ha along with either pendimethalin @ 1.0 kg/ha alone or in combination with bispyribac-sodium 0.025 kg/ha significantly suppressed nutrient depletion by weeds. Increment in grain and straw yield in pendimethalin fb brown manuring and pendimethalin fb bispyribac-sodium fb brown manuring was in the tune of 187.67 and 188.36%, and 45.11% and 41.19% over weedy check, respectively. Similarly, integration of two or more weed management practices enhancedtotal nutrient (NPK) uptake and partial factor productivity of nutrients by direct seeded rice.
