More than 90% of the area under oilseed Brassicas is occupied by the Indian mustard ( Brassica juncea ) because of its relative tolerance to biotic and abiotic stresses as compared to other oilseed Brassica species. Light plays key a role in net primary productivity and is necessary for plant growth , morphogenesis and several physiological processes. The present investigation aimed to assess the effect of low light stress on photosynthetic traits and antioxidative enzymes in Brassica juncea genotypes. Shading was imposed with nets from mid-December to mid-January which cut 25%-30% of natural sunlight. Shading period coincided with the onset of flowering. The results showed that chlorophyll b and antioxidant activities of superoxide dismutase (SOD), guaiacol-peroxidase (G-POD) and catalase (CAT) increased under low light stress at two stages of investigations (10 and 30 days after removal of nets). With shading treatment, soil plant analysis development (SPAD) chlorophyll meter values, chlorophyll a , total chlorophyll, chlorophyll a / b ratio, carotenoid and protein content decreased significantly while malondialdehyde content increased due to damages of plant cells. This study provides valuable information for further deciphering genetic mechanism and improving agronomic traits in Indian mustard cultivated under optimal light requirements.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130274321","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}

But due to geographical location, the country suffers major impacts of climate change and natural phenomena that also influence the production of this crop. The recent Kenneth cyclone that has affected Northern Mozambique, Cabo Delgado and Nampula provinces, is an example of such problems. This study aimed to evaluate the effects of Kenneth cyclone on groundnut cultivation in Eráti and Meconta districts in Nampula province. The research used a questionnaire with closed and open questions to collect data from 31 producers and five traders in Eráti and Meconta districts. Based on the data the sum of the overall average production losses between the two districts was approximately 60%, in which Eráti lost 52% and Meconta 67% of the total production expected for groundnut. The biggest impact was the loss of unharvested groundnut germination and the deterioration of the groundnut in the field while drying. Kenneth cyclone created appropriate conditions for the proliferation of fungus causing aflatoxin, Aspergillus flavus. Samples collected for laboratory analysis showed high levels of total aflatoxins, some 269.4 ppb in Meconta and 148.3 ppb in Eráti. The purchase price of groundnut in Eráti during this period varied naturally based on product quality, with 0.8 US $/kg of groundnut that looks good quality (without the presence of fungus or mould, insect damage, rotten and germinated nuts) and 0.6 US $/kg for the poor quality (presence of fungus or mould, insect damage, rotten and germinated nuts). Kenneth cyclone affected the expectations of farmers in groundnut yields in the 2018/2019 season.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121080431","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}

Based on partial least square (PLSR), multiple linear regression (MLR), support vector machine (SVM), random forest (RF), BP neural network and other machine learning algorithms, the biomass estimation model of potato in different growth stages is constructed by using single variables such as original spectrum, first-order differential spectrum, combined spectrum index and vegetation index (VI) and their coupled combination variables. The accuracy of the models is compared and analyzed, and the best modeling method of biomass in different growth stages is selected. Based on the optimized modeling method, the biomass of each growth stage is estimated, and the yield estimation model of different growth stages is constructed based on the estimation results and the linear regression analysis method, and the accuracy of the model is verified. The results showed that in tuber formation stage, starch accumulation stage and maturity stage, the biomass estimation accuracy based on combination variable was the highest, the best modeling method was MLR and SVM, in tuber growth stage, the best modeling method was MLR, the effect of yield estimation is good. It provides a reference for the algorithm selection of crop biomass and yield models based on machine learning.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128755407","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}

As this residue is more than 60% of the mass of the fruit, there is a problem directed to the discard of the same. One way to add economic and financial value to the passion fruit industry would be to use the waste as a source of fuel in a process of converting biomass to energy. The objective of this work was to characterize samples of passion fruit residues by analyzing the moisture content and the experimental calorific value, aiming at its energy utilization, in order to obtain initial information to help define the best conversion path of this biomass: thermochemical or biochemical. After analysis, it was concluded that the most appropriate biomass utilization route would be anaerobic biodigestion due to the high moisture content presented in the samples (greater than 80%). However, the same ones, if in dry basis, also have high calorific value, compared, for example, with sugarcane bagasse. With the results, it was demonstrated that the biomass of the passion fruit pulp presents itself as a potential alternative for the energy utilization.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"113 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113940627","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}

The nodal cutting technique is the most widely used method for large scale propagation of Casuarina, Eucalyptus and other pulpwood species in India. Tamil Nadu Newsprint and Papers Limited (TNPL) has started large scale multiplication of Casuarina junghuhniana Miq. using mini-cutting technique from indoor clonal mini hedges raised in sand beds. When compared to stem/nodal cuttings, indoor clonal mini hedges raised in sand beds improve the rooting potential, quality of root systems and are timeand cost-saving. The productivity of cuttings is increased five times in indoor clonal hedge orchard than conventional stem/nodal cutting. The rooting percentage also improved to 90% without rooting hormone whereas the same is only 50% in stem cutting. The plant developed through mini-cutting technique has more lateral root system which helps the plants/trees to withstand during heavy winds. Replacing such stump derived stock plants by intensively managing indoor sand bed clonal mini hedges resulted in a noticeable enhancement of cutting capacity for adventitious rooting as well as the overall quality of the plants produced in much shorter period with easier and cheaper maintenance. The study reveals that mini-cutting method is ideal propagation technique for large scale propagation of C. junghuhniana clones in India.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126294636","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}

The morphological variability of Haematostaphis barteri Hook. F. (Anacardiaceae) in Benin (West Africa) was studied, using 11 traits related to panicles, fruits, leaves and leaflets. A total of 1,485 panicles, 1,485 fruits, 990 leaves and 4,950 leaflets were sampled. It was found that the sample provenance and site topography have a significant influence on the morphological traits. The discriminating morphological traits were the length of the panicles, the number of fruits per panicle, the length and width of fruits, the mass of the fresh fruit pulp mass, the length of leaves and petioles, the number of leaflets per leaf, length and width of leaflets. On the basis of these traits, four different morphotypes of H. barteri were identified, with however a small intra and inter group variability. The morphotype from sites established on the tops and the high slopes of hill produced larger and heavier fruits with higher pulp mass. This morphotype could be of interest for future varietal selection programs for the species in Benin.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"12 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114130843","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}

This study investigated the long-term causation between banking sector development and agricultural productivity in the six Central African Economic and Monetary Community (CEMAC) states from 1990 to 2018, hypothesizing no causation between banking sector and agriculture output. With the autoregressive distributed lag (ARDL) model and vector error correction model (VECM), the study demonstrates that banking sector and agricultural productivity in the CEMAC region are related. It implies long-run relationship exists between banking sector and agricultural productivity in the CEMAC zone. The results reveal that bidirectional causality exists between banking sector and agricultural productivity in the CEMAC region. This is insinuating that in the CEMAC region, agricultural productivity and banking sector development are operating in mutualism. The findings indicate the reason to establish the banking sector using proper macroeconomic, legal and regulatory policies to boost agricultural productivity by creating incentive systems that channel more credit to agricultural investment and promoting the banking system.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115795054","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}
