“…SRI machine transplanting with conoweeding four times at 10 days interval significantly lowered the weed dry weight followed by PE Pretilachlor and EPOE Bispyribac sodium. This is in conformity with the findings of Uprety (2010), who revealed that machine planting with frequent conoweeding had encouraged frequent loosening of soil stimulating aerobic conditions with concomitant reduction in the density of weeds, dry matter. Also incorporation of weeds manure to served as the crop.…”

Field experiments were conducted in clay loam soil of wetland farm, Tamil Nadu Agricultural University, Coimbatore during rabi, 2011-12 and 2012-13 to evaluate different crop establishment methods and weed management practices in lowland transplanted rice. The experiment was laid out in strip plot design with three replications. The treatments consisted of three crop establishment methods in horizontal strips and six weed management practices in vertical strips. The results of the study indicated that mechanical transplanting at 30 x 20 cm with conoweeding four times at 10 days interval starting from 10 DAT resulted in higher grain yield, higher net returns and B:C ratio. This practice was comparable with mechanical transplanting at 30 x 20 cm with preemergence application of pretilachlor @ 0.75kg a.i. ha -1 + early post emergence application of bispyribac sodium @ 20g a.i. ha -1 coupled with conoweeding at 40 DAT.

An field experiment was conducted during kharif season of 2017 and Rabi season of 2018 to study the effect of crop establishment methods viz., System of Rice intensification, Machine planting, Conventional method of transplanting and weed control practices ay application of pre emergence herbicide (Metsulfuron Methyl 10 % -Chlorimuron Ethyl 10 % )10 and 20 g ha -1 and, Butachlor10 g ha -1 and 2.5 lit per ha -1 + three mechanized weeding at 25,35,45 DAT ,hand weeding on 20 DAT, four mechanized weeding at 15,25,35,45 DAT and hand weeding twice at 20 and 40 DAT. The experiment was laid out in split plot design with a main plot of three planting methods and seven weed control practices as sub plots and were replicated twice. SRI rice registered significantly higher grain and straw yield and it was comparable with other planting methods during both the years. The lowest grain yield was observed at conventional method of planting. Among the weed management practices, SRI planting methods +pre emergence application of (Metsulfuron Methyl 10 % -Chlorimuron Ethyl 10 %) 20 g ha -1 cono weeding thrice registered lower weed density and dry weight which resulted in significantly higher grain yield and it was comparable with application of Butachlor 2.5 lit per ha -1 + three mechanized weeding. The density of weeds as well as dry weight was higher in conventional method of planting. The highest weed control efficiency was recorded in SRI method of planting and pre emergence application of (Metsulfuron Methyl 10 % -Chlorimuron Ethyl 10 % )@ 20 g ha -1 .

“…As a result of which, the country attained selfsufficiency in rice food production [18,20]. Similarly, Nepal's adoption of mechanized farming in rice resulted in a lowering of the production cost by up to 27 % [21]. In [22] it was reported that the use of integrated pest management, row seeding, and harvesting by machine and rice dryers proved to increase paddy yields.…”

Technology-driven innovation has been generally believed to play a key role in the building of a sustainable economy. The object of the research is the audit of agricultural technology for businesses in Nigeria. This research aimed to audit the existing technologies for agricultural businesses in Nigeria, in a bid to determine the technological strengths, weaknesses, opportunities and needs that are required to transform the sector to an enviable status. The methodology involved the use of a well-structured questionnaire for data collection from 133 randomly selected agriculture-based firms, spread across the country. The instrument inquired about the technology use, needs, and prospective technological potentials. Issues relating to effective utilization, technology diffusion, and factors affecting the firms were also assessed. The results of the technology audit of the Nigerian agriculture sector revealed the prevalence of medium and low-classed technologies among the surveyed firms, while a majority desired the technologies in the medium-to-high category. Firms scarcely (4.4 %) deploy high technologies, and effective diffusion of available technologies is due largely to human/technical factors. A good percentage of respondents affirmed competency and continuous training as critical factors for the effective utilization of technologies. Finances are critical not only to acquire, but also to run, maintain, hire experts, and perform other necessary activities that would enhance effective use of technologies. The present results revealed that most firms do not opt for high technologies mainly because of a huge capital base, and unavailability of basic infrastructures such as power, and space which many of the surveyed firms considered unsurmountable. Thus, a lot is required technology-wise for Nigeria to achieve sustainable and innovative agricultural growth.
