An experiment was conducted in IAAS, Lamjung research field in 2017 in spring Maize with split plot design to evaluate the effect of weed management practice and tillage system on productivity of spring maize. In tillage system, no-till and conventional tillage were kept as main factor whereas seven weed management practices (viz. sequential application of atrazine at 0.75 kg a.i. ha -1 and 2,4-D at 1.5 kg ha -1 ; pre-emergence tank mix application of atrazine at 0.75 kg ha -1 and glyphosate at 2.5ml lit -1 of water; pre-emergence tank mix application of atrazine at 0.75 kg ha -1 and pendimethalin at 2ml lit -1 of water; cowpea co-culture; black polythene mulch with control treatment weed free and weedy check as sub-plot. Tillage method had not significant effect on the weed dry matter accumulation in different stages. However, weed dry matter accumulation was varied with different weed management practices. The weed check plot was of highest dry matter accumulation (273.38g m -2 , 361.95 g m -2 and 235.95 g m -2 in three different stages (30, 60 and 90 DAS respectively). The highest grain, straw yield and yield attributes was found in plastic mulch plot and no-till system with less severe to weed infestation and index which is statically at par with intercropping with cowpea. Though none of weed management practices completely eliminated weeds, black polythene mulching resulted in best grain yield. Besides the environmental protection, cowpea co-culture treatments yielded almost similar grain yield as compared with common herbicidal weed management practices.

This research was conducted in the Ramechap and Dolakha regions of Nepal to analyze the role of AFEC in the adoption of SSMP technology. A total of 120 samples were randomly collected from 4 VDC, namely Sindrawoti, Chisapani, Namdu and Puranogaun. Both qualitative and quantitative information were collected using a semi-structured questionnaire, household survey, important informative interview and focus group discussion. As a result of the study, it was found that the effectiveness of these committees was very important in participatory planning, resource mobilization and agriculture service presentation. Participation of farmers in local level planning is significantly higher in village development committee (VDC) with AFEC (73.3%) than VDC without AFEC (43.3%). AFEC farmers have begun to receive technical service with 2.84 index values compared to farmers without AFEC. The average adoption level is significantly higher in VDC with AFEC (43.69% household(HH)) than with non-AFEC (11.78%). According to the Logit regression model, HH development training and the presence of AFEC were statistically significant in determining the adoption of SSMP technology. ÖZET Bu araştırma, AFEC'in SSMP teknolojisinin benimsenmesindeki rolünü analiz etmek için Nepal'in Ramechap ve Dolakha ilçelerinde gerçekleştirildi. Toplam 40 örnek, 4 VDC'den, yani Sindrawati'den ve Chisapani Namdu, Puranogaun'dan rasgele toplanmıştır. 2 VDC'deki bu 4 VDC'nin içinden AFEC kuruldu. Hem nitel hem de niceliksel bilgi yarı yapılandırılmış anket kullanılarak hanehalkı araştırması, önemli bilgilendirici görüşme ve odak grup tartışması ile toplanmıştır. Çalışmadan, katılımcı planlama, kaynak seferberliği ve tarım hizmeti sunumunda bu komitelerin etkinliğinin son derece önemli olduğu ortaya çıkmıştır. Çiftçilerin yerel düzey planlamasına katılımı AFEC'li VDC'de (% 73,3) AFEC'siz VDC'lere (% 43,3) göre anlamlı derecede yüksektir. AFEC'li çiftçiler, AFEC'siz çiftçilere kıyasla 2.84 endeks değeri ile teknik servis almaya başlamıştır. Ortalama benimseme düzeyi AFEC'li VDC'lerde (yüzde 43.69 HH), AFEC olmayan VDC'ye (yüzde 11.78) göre anlamlı derecede yüksektir. Logit regresyon modeline göre HH geliştirme eğitimi ve AFEC varlığı SSMP teknolojisinin benimsenmesinin belirlenmesinde istatistiksel olarak anlamlı bulunmuştur.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
