Therefore, the need for soil quality index was formulated with scientific strategies. Heber Soil Quality Index (HSQI) was exploited in this study to understand the overall quality of Thanjavur region for better rice and sugarcane production. Thanjavur is one of the important cities of Tamil Nadu often referred as rice bowl of the state. Different varieties of crops are being cultivated in the district which includes paddy, sugarcane, pulses and coconut. The farmers in the district are very progressive and innovative in adopting modern technologies and crop varieties. The ultimate HSQI values of the samples examined in the current inspection ranged from 66.26 – 80.27 which suggests that they are of medium to good quality. The index was found to be time saving and economical way of assessing the fertile nature of the soil for the effective cultivation of rice and sugarcane. The twelve parameters in the HSQI are proved highly useful.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130098202","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 a way forward, the adoption of water, energy, food, and soil security are viewed as a long-term solution to address these problems. This mini review presents an overview of the capacity of enhancing soil health through the integration of biobased residues (BBR) as a sustainable soil amendment. The perspective of how the use of BBR fits within the concept of soil health and soil security, and how it relates to sustainability indicators was also evaluated. Furthermore, the use of BBR was assessed using criteria considered important for soil and crop performance, and an overall evaluation of sustainable outcomes. We concluded that the application of BBR to agriculture offered a sustainable approach to address current environmental challenges, including the diversion of landfill organic wastes to agricultural land.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132252335","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 soil salinization increases and farmland decreases globally due to climate change, irrigation and urbanization, a big challenge is to balance the reducing of soils areas for crop cultivation and the increasing of requirement of food and energy. It is considered as a desirable and sustainable strategy to utilize the saline soils by cultivating the salt-tolerant crop varieties or halophytes for agricultural usage. The cultivation of salt-tolerant plants on saline land has obtained a more and more increasing of interest. In the past a few decades, a lot of work has been done in the utilization of salt-tolerant plants and halophytes for agriculture usage in saline soil in China. The usage value according to the food, vegetables supply, saline land remediation, bioenergy production, and other economic value were briefly summarized. Furthermore, a better method to develop and utilize of saline land and the valuable information for future investigation of saline land were provided.

{"title":"Goat Breeding Objectives in Relation To Agroecological Zonation Under Dryland Farming Conditions of North Kordofan, Sudan","authors":"F. M. E. Hag","doi":"10.33552/WJASS.2020.05.000604","DOIUrl":"https://doi.org/10.33552/WJASS.2020.05.000604","url":null,"abstract":"Twelve focus group discussions and 164 individual farmer interviews were held in 12 villages under dryland farming in different agroecological zones in North Kordofan, Sudan, during November-December 2018. The aim was to describe goat breeding objectives, ownership, and population distribution in relation to agroecological zones. Data and information collected were analyzed for descriptive statistics using SPSS (ver. 24). The highest goat numbers were in the semidesert (41.9%) and arid (35.0%) zones, holding over 75% of goat population. Overall percentage of households owning goats was 70.9%, with average flock size of four heads, mostly (94.9%) owned by women. Mature does constituted over 70.0% and female yearlings about 21.9.0%. No controlled mating over goat flocks was practiced, with an average of 77 goats per breeding buck. Kidding occurs mainly during the rainy and winter seasons. Lactating does were mostly (99.5%) milked once a day every morning. Milk production was ranked as the most important reason for raising goats across all agroecological zones, with highest indices at the semiarid on sand (index 0.886) and semiarid on clay (index 0.723) zones, followed by the semidesert zone (Index 0.633), and lowest indices (Index 0.500) at the desert and arid zones. Meat production was ranked 2nd in the desert (index 0.270) and semiarid on clay (index 0.262) zones, while income generation was ranked second across semidesert (index 0.300), semiarid on sand (index 0.345) and arid (0.068) zones. It was concluded that goat breeding objectives in the region should focus on milk production. Nonetheless, the multipurpose nature of goats (milk, meat, income generation, etc.) under low-input traditional dryland production systems should be taken into considerations when attempting improvement programs. Furthermore, there is a high need for genomic/genetic characterization of different goat subtypes/breeds in North Kordofan and Sudan at large.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128409311","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}

Its protein has a profile of amino acids similar to that of soybean. A completely randomized design with three replicates was used in a 42 days study to determine digestibility and growth performance of 150 Heterobranchus longifilis fingerlings. Graded levels (0, 5, 10, 15 or 20) % of dried MLM was used to replace soybean meal in a 42.5% crude protein H. longifilis diet fed at 5% in the first 2 weeks and subsequently 3% body weight. The results showed that there were significant differences in weight gain (WG) and specific growth rate (SGR) of the fish with the significant highest observed in the group that fed on diet 2 with 5% MLM supplementation (P<0.05) though not significantly different from the control (P>0.05). The significant poorest WG and SGR were obtained in the group that fed on diet with 20% level of MLM supplementation (P<0.05). There was no significant difference between treatments in terms of initial weight, feed intake and survival (P>0.05). However there were significant differences in feed conversion ratio (FCR), SGR, total length and standard length among the groups that fed on diets with 15% and 20% supplementations (P<0.05). The haematocrit and hemoglobin were also significantly reduced in the group that fed on the highest level of supplementation (P<0.05). The in-vitro trial revealed significant reduction in digestibility with increase in MLM supplementation level (P<0.05) the tannin and phytic-acid levels following the same trend. However there was no pathological defect observed in the fish from all the groups. There was no significant difference in the hepathosomatic index.

It was concluded that 5 – 10% MLM supplementation could be used in the diets of H. longifilis to obtain a reduction in cost of feeding it at 11.2% and 23.5% per 100Kg feed respectively.
