To evaluate the effect of different sowing times on wheat varieties, an experiment was conducted at Directorate of Agricultural Research (DoAR), Madhesh Province, Parwanipur, Bara, Nepal during the winter seasons of 2018-2019. The experiment was conducted in a split-plot design with three replications that includes twelve treatments combination having three sowing dates as a main-factor ( 10th November, 25th November, and 10th December) and four promising wheat varieties (BL 4407, BL 4621, BL 4699, and Vijay) as a sub-factor. There was a significant effect of date of sowing on spike length, tillers, grain yield and 1000 grains weight, but the plant height and straw yield were not affected significantly by sowing dates. Variety had no significant effect on plant height and straw yield, but influenced significantly the spike length, effective tillers, 1000 grains weight and grain yield. The 25th November sown wheat crop gave a significantly higher grain yield (3925 kg ha–1) and straw yield (8044 kg ha–1) but declined in grain yield noted by 11-14% in the 10th November and 10th December sown wheat. A promising wheat variety BL 4407 (4017 kg ha–1) produced the highest yield, (20% more) compared with released variety Vijay (3203 kg ha–1).

The experiment was laid out in split plot design with 8 treatments and 3 replications. Main plot was for two tillage methods [Zero tillage (ZT) and conventional tillage (CT)] and sub-plots for 4 different cropping patterns (maize-wheat, maize-lentil, soybean-wheat and soybean-lentil). In zero tillage, the soil was disturbed only along the rows for making seeding furrows and the previous crop residues were left anchored. The rest of the crop management practices were adopted as per the recommended practices. The data were analyzed using GenStat software. The results revealed that tillage treatments did not influence the winter crop yields in 2019, but in 2020, ZT recorded a significantly higher yield of wheat (4.9 Mt ha-1) compared to CT (3.4 Mt ha-1). Similarly, irrespective of crop establishment methods, pooled system yields and benefit: cost ratios were significantly influenced by various cropping patterns. The significantly higher system yield was recorded with maize-wheat (9.0 Mt ha-1) and the least with the soybean-lentil (5.2 Mt ha-1) cropping systems. Improvements in the soil properties were observed as SOM was 14% higher in ZT compared to CT. Similarly, average soil moisture and soil temperature in ZT and CT were found to be 30.2%, 27.5 °C and 28.7%, 29.4 °C, respectively. It is suggested that CA could possibly be an alternative production system for the fragile agro-ecology in the mid-hills of Nepal.","PeriodicalId":316755,"journal":{"name":"Agronomy Journal of Nepal","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122106925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With an objective of selecting appropriate variety, sowing time, sowing method, seeding rate, priming techniques and weed management practice for lentil cultivation four different experiments were conducted at Grain Legumes Research Program, Khajura, Banke in two winter seasons of 2017/18 and 2018/19.  The experiment on sowing time was conducted in split-plot design including four lentil varieties and four sowing dates, while the seeding rate experiment was laid out in split-split-plot design with the treatments of two varieties, two sowing methods and four seed rates. Similarly, seed priming and weed management trails were conducted in RCBD with ten treatments. All the experiments were replicated three times. The highest seed yield of lentil was recorded from the early maturing lentil varieties, i.e. PL 4 (934  kg ha–1) and ILL 7979 (864 kg ha–1). Similarly, lentil sowing on October (940 kg ha–1) produced the higher seed yield than sowing on November (682  kg ha–1). Likewise, the highest seed yield of lentil was recorded from the use of seeding rate 60 kg ha–1 (890 kg ha–1), but it was statistically at par with the seeding rates of 40 kg ha–1 (865 kg ha–1) and 50 kg ha–1 (855 kg ha–1). Differently, the seed yield of lentil didn’t differ significantly under line (856 kg ha–1) and broadcasting (847 kg ha–1) methods of sowing. The seed priming with a 250 ppm solution of sodium molybdate (Na2MoO4) produced significantly the highest seed yield (961 kg ha–1) in lentil. Similarly, the highest and statistically similar seed yield of lentil was recorded with the weed management practice of two hand weeding (924 kg ha–1) and the use of Pendimethalin (898 kg ha–1) and Pendimethalin-Quizolofop-ethyl (857 kg ha–1) as a pre-emergence.
