The experiment consisted of thirteen treatments, of which twelve combinations were of four doses of zinc (Zn) (2.5, 5.0, 7.5 and 10 kg ha-1), three frequencies (only once, alternate year and every year) of application along with control with the no-zinc application. Rice and wheat crops were grown in succession with the recommended dosages of fertiliser viz. 120:60:40 of N: P2O5: K2O applied as Urea, DAP, and Potash, respectively. Surface soil samples (0-15 cm) were collected after the harvest of the wheat crop in the year 2018, i.e. after completion of six years of the experiment, and analysed for soil physical and chemical properties.

Wheat is susceptible to a variety of diseases and insect pests, including birds. Birds attack on standing crop are not very often and extent and pattern of damage varies considerably, however, its management practices is generally not taken in to account. The bird preferred to attack wheat crops while they were in the reproductive stage, especially during milking to dough stage. The data collected over the course of a two-year field study in the Kashmir valley at Research Farm Srinagar (Jammu and Kashmir) has been subjected to Random Forest model to determine whether there is a trait-specific specific preference for attack if any. Random forest (RF) model identified five major features out of 13 selected features of wheat germplasm with seventy percent accuracy for parrot birds’ preferred to attack on wheat germplasm. RF Model suggests that taller height, having long spikes and a greater number of ears, along with more biomass and grain yields, could be possible traits that bird pest target during the reproductive stage. It was inferenced that the average performance of the random forest model demonstrated with model accuracy (71%), sensitivity (0.77), kappa 0.41 and receiver-operating-characteristic (ROC-0.74) and showed good fit for classification of parrot attack on wheat germplasm.","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91050666","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}

Rapeseed-mustard has great potential under residual moisture after the harvest of Kharif rice in North Eastern states. It is a major source of income especially to the marginal and small farmers in rainfed areas of Manipur. Sample consisted of randomly selected 29 farmers who were growing rapeseed-mustard under FLDs. The results revealed that improved technology recorded a mean yield of 8.77 q/ha which was 20.55 per cent higher than obtained under farmers’ practice (7.27 q/ha). The study also showed that reduction in technology index from 10.90 per cent during 2017-18 to 6.49 per cent during 2019-20 exhibited the feasibility of demonstrated technology. The lower value of technology index, the more is the feasibility of technology. Further, it was found that the adoption of improved technologies not only increased the yield but also yield attributing traits of rapeseed-mustard and benefit cost ratio. Hence, there is a need to disseminate the improved technologies amongst the farmers with effective extension methods like training and demonstrations to utilise the rice fallow areas for increasing the cropping intensity as well as to increase crop production and productivity. The farmers’ should be encouraged to adopt the recommended package of practices for realizing higher returns.","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74509424","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}

Encapsulation efficiency of gum arabic and maltodextrin (GAMD) EOs increased from 26 to 31% for 4 to 8% of EOs concentration. The sizes of all the particles were found in the range of 1-10 μm. The reduced size in case of EOs loaded GAMD-EOs encapsulates may be due to the application of spray drying method used during the preparation. Maximum germination inhibition was observed with P. minor as compared to the E. crus-galli L. The probable reason behind this may be the relatively smooth seed coat, smaller weight to volume ratio of P. minor as compared to the E. crus-galli L. Among all the treatments basal application of encapsulates with 8 % essential oil was found more lethal and result in maximum phyto-toxicity by registering less shoot length and root length and fresh biomass weight. Also, the individual constituents of the EOs can be explored for their use as herbicides and then their encapsulated formulations can be used for scale up in the field conditions.","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88180137","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}
