Dwarfing is based on the principle of making the optimal use of vertical and horizontal space per unit time and harnessing the highest potential returns per unit of inputs and natural resources. Dwarfing in fruit crops can be accomplished through a variety of methods, including the use of dwarfing rootstock, the selection of spur type scion cultivars, use of interstock, pruning, root pruning, various training systems, girdling, scoring, bark invasion and the application of growth retardants. One strategy for promoting early fruiting, less vigour and increasing production is to utilize dwarf root stocks. The mechanism underlying dwarfing involves anatomical, physiological and biochemical changes. It has been proposed that dwarfing rootstock or interstock control tree size by regulating the auxin that passes through the rootstock or interstock’s bark. Paclobutrazol retards growth, shoot elongation and reduced internodal length by inhibiting gibberellins synthesis. Dwarfness can be imparted by the using incompatible rootstock. Dwarfing can be induced by inducing viral infection, although, it is not commercially adopted. Recombinant DNA technology has recently expanded the gene pool that can be managed to cause dwarfism and maximize benefits in horticulture crops.\u0000","PeriodicalId":7417,"journal":{"name":"Agricultural Reviews","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81516641","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}

In a thresher, rasp bar, spike tooth, peg tooth and wire-loop type threshing elements can be fitted with the threshing cylinder irrespective of direction of crop feed and flow. Different elements are responsible to thresh the crop with different actions which include impact, rubbing, combing, squeezing and their combination. This review was carried out to explore the effect of different threshing elements and threshing methods on performance of paddy threshing. Unlike threshing of other cereal crops, hull removal is not required in paddy. Selection of threshing elements based on the crop to be threshed. The type of threshing element determines the threshing efficiency, energy requirement and grain loss. Among rasp bar, spike tooth, peg tooth and wire-loop type threshing elements, wire-loop type was found to be most suitable for paddy threshing. Factors like cylinder speed, cylinder type and diameter, concave clearance and throughput rate affect the threshing performance. A low speed of cylinder produces more un-threshed grains. It can be compensated using for axial flow thresher as it has high crop retention period. Contrarily, a high speed is responsible for better threshing efficiency along with the more grain breakage and energy consumption. Using tangential flow thresher crop retention period can be minimized. The work rate of pedal and power thresher was, respectively 2 and 10 times more than that of manual threshing. The average threshing efficiency of pedal thresher, power thresher and combine harvester was reported to be 97 to 99%, 96.30 to 99.75% and 98.5%, respectively.","PeriodicalId":7417,"journal":{"name":"Agricultural Reviews","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78022540","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}

Among other things, understanding the economics of subsistence agriculture will go a long way in making its practice viable by making sure the help that these subsistence farmers need are provided. Therefore, the present study attempts to study the economics of paddy-wheat and maize-wheat rotation cropping system practiced by subsistence farmers of Himachal Pradesh whose agriculture sector is known for its diversification towards high value crops. Methods: The study has used survey data collected from 60 randomly selected households from Rait block of district Kangra, Himachal Pradesh. 30 households practicing paddy-wheat rotating cultivation are selected from Boh and Drini village and 30 households doing Maize-Wheat rotating cultivation are from Machhlini, Panjol, Khridi, Rulede and Lahri village. The study is based on primary data which has been collected through a pre-tested schedule. Using the primary data, we have brought out factors other than self-consumption needs that determines choice between two farming systems and also two group of farmers are compared in terms of productivity, cost of cultivation and net returns from cultivation. Result: Our study found that irrigation facilities play an important role in the choice between the two cropping systems. Return from cultivation is negative for both groups of farmers if imputed value of family labour is included. Performance of paddy-wheat farmers is significantly better than maize-wheat farmers in economic terms in the study area.\u0000","PeriodicalId":7417,"journal":{"name":"Agricultural Reviews","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88228407","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}

So, to meet these challenges, there is a need to develop new crop varieties containing traits resistant against abiotic and biotic stresses and enhanced input use efficiency. Compared with domesticated cultivars, crop wild relatives maintains much higher level of genetic diversity. The high nutrient and bioactive content of many wild edible plants make them valued contributors for balanced diet and play significant role in human nutrition. In this review article, we discussed the importance of crop wild relative in crop improvement programs by giving examples of wild relatives that have been used to enhance abiotic and biotic stress tolerance and yield in various crop species. The advancement in DNA sequence technology enables plant breeders to produce high quality food. Further, combination of re-sequencing and de novo sequencing are efficiently used to explore genomic variation in crop wild relatives and moreover the genome analysis study results in detection of beneficial alleles in wild relatives which has been lost in cultivated species. Thus, conservation of genetic pool of crop wild relatives is essential to maintain sustainability of agriculture and food production.\u0000","PeriodicalId":7417,"journal":{"name":"Agricultural Reviews","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83856216","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}

Various management practices like seed rate, planting time and method, plant population, intercultural practices, weed management, fertilizers and irrigation application, intercropping, mulch application for soil moisture conservation, etc. results in increased water use efficiency (WUE) of the crop. Also selection of crop which necessities lesser water usage for crop growth encourages diversification. Greengram is paramount preference for areas with scarcity of good quality water. Being rich in protein content and minerals, it serves the purpose of healthy regimen. Timely sown crop results in better growth due to favorable climatic conditions. Whereas late sown crop is adversely affected by pest attack, temperature fluctuation etc. ensuing reduced water use efficiency and yield diminution. Planting method, plant population and intercultural operations are essential in agronomic point of view. Selection of apt irrigation regimes directly effects water use efficiency in any field study. As crop productivity is equal with water productivity, the efficient irrigation schedule assures water saving without affecting the crop yields. Because, where no irrigations are given, the water use may be low by the crop but, this may affect crop yields. Use of recommended fertilizers may facilitate the use of irrigation water by crop for its better growth and improved WUE. Insertion of low water requiring crop as intercrop can unswervingly increase water productivity. Applying mulch conserve moisture as its use lowers evaporation from soil surface. Usage of weed management practices conserves irrigation water as weeds compete with crop plants for water and nutrients. Wherefore, the present review will reckon upon the impact of innumerable agronomic interventions in increasing water productivity.","PeriodicalId":7417,"journal":{"name":"Agricultural Reviews","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72943137","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}
