The present work evaluated the effect of microwave on germination of six weed species: wild oats, darnel, white bursage, Giant ragweed, field bindweed and dodder and improvement of some traits of two imported crops soybean and wheat (oil percentage of soybean seeds and protein content of wheat grains), which were contaminated by these weed species. Results showed that microwave power and time required for preventing germination varied considerably among the species studied. Microwave power 80% for 15 minutes prevented completely germination percentage of wild oats and darnel and reduced germination percentage of field bindweed to 10%. The microwave power 50%, 15 minutes was enough to prevent seeds germination completely and weaken dooder quarantine. In regard to Giant ragweed and white bursage, under all microwave power treatments, there were no germination of these weeds. Microwave powers 50% for 10 minutes and 80% for 15 minutes had no effect on the oil percentage extracted from soybean seeds and protein content of wheat grains, respectively. The present results suggest clearly that the exposure to microwave can weaken quarantine weed seeds in imported soybean and wheat without injury of oil percentage of soybean seeds and protein content of wheat grains.","PeriodicalId":42226,"journal":{"name":"Egyptian Journal of Agronomy","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41776942","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}

Guar gum is important product which is obtained from guar seed and has worldwide uses in different industries. Therefore, there is a dire need of evolution of new high yielding, short duration and early maturing varieties of guar. Keeping in view the above facts, Agricultural Research Station, Bahawalpur is conducting research to develop new varieties. The present newly developed variety BR-21 (strain name S-5823) is high yielding, short duration, non-hairy with a wider range of adaptability. Yield data (grain yield) were collected from the guar varietal performance trials conducted over eight consecutive years (2011-2020). This strain performed better when evaluated/tested in 7 different yield performance trails including commercial variety as a check from year 2013-2018. The BR-21 also performed excellent in the agronomic trials (Sowing date, fertilizer requirement, row spacing, and irrigation levels) compared to check variety in different years of study. Finally, it is concluded that BR-21 is a non-hairy and very easy to harvest than previous guar varieties. It contains high gum contents (34.9%) than check variety. It is high yielder, early maturing and requires very low inputs. It is comparatively resistant to insect pests and diseases. It is short duration variety, therefore, wheat, raya, chickpea and other Rabi crops can be sown well in time.","PeriodicalId":42226,"journal":{"name":"Egyptian Journal of Agronomy","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49240001","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}
