Effect of biofertilizers and bioregulators on growth, yield and nutrient status of strawberry cv. Sweet Charlie

Not AvailableField experiment was conducted to study the response of nitrogen fixing bacteria with chemical fertilizers in conjunction with plant bioregulators on growth, yield and nutrient status of strawberry cv. Sweet Charlie. Nitrogen fixing bacteria and bioregulators were observed to exhibit significant effect on the growth characters in strawberry plants. The maximum growth in terms of plant height, number of leaves, leaf area, crowns/plant and total biomass were observed in the treatment consisting of Azotobacter + Azospirillium + 60 kg N ha-1+ 100 ppm GA3 . This treatment also contains highest chlorophyll content in leaves. Highest fruit set, yield and optimum fruit quality was recorded in plants inoculated with Azotobacter and Azospirillum along with 60 kg N ha-1 (50% N of the standard dose) and 100 ppm GA3. The plant nutrient status was much influenced by combined use of biofertilizer and bioregulators. Dual inoculation with Azotobactor and Azospirillum along with 60 kg N ha-1 and 100 ppm GA3 application resulted in maximum N and Mg content in plant while the maximum Zn content was obtained in dual inoculation along with 90 kg N ha-1 and 100 ppm GA3. However, maximum K content was recorded with 100 ppm BA treatment alone.Not Availabl

Not AvailableIndian cherry (Cordia myxa L.), locally called lasora or gonda, is an important multipurpose fruit tree species distributed in arid and semi-arid regions of India. Its versatile adaptability to poor soils, wastelands and tolerance capacity to water stress makes it suitable plant for arid ecosystem. The species is known for its nutritious fruits and diverse uses of other plant parts. It is generally planted as shelter belt on farm boundaries, but now a days, it is grown as planned orchard to fetch premium prices from its fruits in summer season (March-April). In view of its benefits both in tangible and non-tangible terms, the research work on its genetic improvement and production technologies has been attempted at various ICAR institutes and Agricultural Universities. High yielding varieties like Maru Samridhi, Karan Lasora and Thar Bold have been developed by selection from seedling population. The vegetative propagation technique, rootstocks, canopy management and crop regulation by defoliation and irrigation scheduling have been standardized. To review the available information on its germplasm collection, evaluation and improvement as well as production, and post harvest management under-utilized may serve the purpose for benefits of growers, researchers, and policy makers.Not Availabl

Not AvailableOut of various species of Ziziphus, there are three, namely Z. mauritiana Lam., Z. rotundifolia Lam. and Z. nummularia (Burm. f.) wt., that are most abundantly occurring species in drier part of India. Z. mauritiana has socio-economic importance in the rural life of the local people being part of each and every farming system supplying food, fuel, fodder, fencing and nutritious fresh as well as value added products. Z. nummularia is an excellent top feed species producing nutritious leaves locally called ‘Pala’ serve as good source of fodder for desert livestock such as sheep, goat, camel and cattle. Z. rotundifolia have much value as timber however its importance lies as rootstock for vegetative propagation and played an important role in commercialization of cultivated Z. mauritiana. These species have tremendous potential for improvement and utilization as commercial crop of arid regions. The paper is an attempt to synthesize available information on Ziziphus species, their distribution, botanical description, nutritional and medicinal value, and experimental findings on genotypic diversity, adaptability under progressive drought situation, mass multiplication method, pruning, system based production and rejuvenation of unproductive trees. These information and research findings on improvement, production and utilization of jujube would create a strong commercial opportunities in arid and semi arid regionsNot Availabl

Not AvailableDuring recent times, the whole globe is facing problem of climate change and its impact on agricultural production. Fruit crops like ber, lasora (gonda), karonda and khejri can be grown under arid and semi-arid situation as rainfed or with supplementary irrigation from harvested rainwater during establishment and other critical stages. Recent technological intervention in these indigenous fruit-cum vegetables crops are being discussed.Not Availabl

Not AvailableThe hot arid regions in India is spread in an area of 31.7 m ha, majority area being in Rajasthan (61%). The great Indian Thar desert is also located in this region. This region receives vary low rain fall with erratic distribution. Presence of harsh climatic condition such as high evapotranspiration, low relative humidity, with high aridity index and high wind velocity are other disadvantages. The soils are also light textured, less fertile, and prone to wind erosion. About 90 per cent of the area is dependent on monsoon rain for growing of annual crops which often fails due to insufficient rain or improper distribution. Despite these limitations, the region has good floral and faunal diversity that supports high human and livestock population. Many drought hardy perennial fruits and vegetables are grown with annual crops to complement farm income. Certain fruit crops like pomegranate (Punica granatum), Indian jujube (Ziziphus mauritiana Lam.), aonla (Emblica officinalis), date palm (Phoenix dactylifera) and Citrus species are grown commercially in irrigated areas. Many underutilized fruit crops also grow naturally or are cultivated. These include kair (Capparis decidua), lasora (Cordia myxa) jhar ber (Ziziphus nummularia), bordi (Ziziphus rotundifolia) pilu (Salvadora oleoides), khejri (Prosopis cineraria), phalsa (Grewia subinaequalis), Bengal quince (Aegle marmelos), karonda (Carissa carandas), prickly pear (Opuntia ficus-indica), kachri (Cucumis melo var. callosus) and snap melon(Cucumis melo var. momordica) etc. Most of these species are drought hardy with less incidence of pests and diseases yet give good yield despite environmental constraints. They serve as a source of nutrition for rural people being rich in vitamins, minerals, dietary fibres and other bioactive compounds. Germplasm collection, evaluation, conservation, ethnomedicinal values, improvement, propagation, agrotechniques, post-harvest management, value addition and future prospects of some of these crops are discussed in the paper.Not Availabl
