The zero-tillage with crop residue at 3.5 t/ha (ZT + R) and conventional tillage with crop residue at 3.5 t/ha (CT + R) enhanced the grain yield (6.2–17.0%) of maize compared to CT without residue (4.40 t/ha). High cost of cultivation was recorded in CT + R (44.8 × 103 `/ha), while high net returns were found in ZT + R (37.6 × 103 `/ha). In ZT + R, the addition of wheat residue enhanced N, P, and K uptake in grain by 19.41, 12.81 and 13.92%, respectively over CT. Available N (182 kg/ha), available P (13.8 kg/ha), and exchangeable K (318 kg/ha) were found highest with ZT + R.

Although the application of vermicompost @ 1.5 t/ha resulted in the maximum grain yield (3.22 t/ha) and nutrient uptake (44.6 kg N, 16.4 kg P and 39.0 kg K/ha), mustard-cake @ 0.5 t/ha could be an alternative option owing to near-maximum grain yield (3.11 t/ha) with high protein content (7.1%), medium aroma (score 1.7), maximum net income (`51,040/ha) and benefit: cost ratio (2.01) in hill zone of West Bengal.\u0000","PeriodicalId":35528,"journal":{"name":"Indian Journal of Agronomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139788203","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}
