Molecular identification of blast resistant genes in rice germplasm from the North-eastern region of India
Rice blast disease caused by the fungus Magnaporthe oryzae is one of the most devastating diseases causing huge losses worldwide. In the present study, 14 major blast resistance genes were investigated in rice genotypes originating from northeastern region of India. Based on phenotypic evaluation, 60 genotypes were classified into five distinct groups: resistant (1), moderately resistant (10), moderately susceptible (15), susceptible (21), and highly susceptible (13). The genetic frequencies of the 14 major blast resistance genes were between 11.66% and 100.00%, with only two genotypes possessing a maximum of 14 blast resistance genes. The cluster and population structure analysis grouped the landraces into three groups. Through principal coordinate analysis, the scatter plots partitioned the resistant, moderately resistant, moderately susceptible, susceptible and highly susceptible genotypes into different groups. According to the PCoA analysis, the first two axes explained 19.12% and 16.18% of the total genetic variation, respectively, contributing a total of 35.31% of genetic variation. Similarly, model-based population structure analysis differentiated the landraces into three subpopulations, SP1, SP2, and SP3. Interestingly, the cluster analysis and population structures were associated respectively, such that The SG1 consisted of 28 genotypes, of which eleven (13.33%) were medium resistant. The SG2 comprised 18 genotypes, of which seven (37.55%) were medium susceptible. Similarly, SG3 included 14 genotypes with a high number of susceptible genotypes. The present study represents a valuable blast resistance genetic resource that could be used for identification of new R genes, and genomic studies donors for blast resistance.
A study on the role of Non-Wood Forest Products (NWFPs) on Tribal livelihood development.
Tribal economy and development is mainly dependent on the Forest and Non wood forest products. The non wood forest products are mainly the products and services availed from the other those timber products of the forest and the fringed areas. Traditionally these forest products are having direct impact on the livelihood of the tribal communities. This study has been designed to analyse the role of the Non wood forest products on the livelihood of the tribal communities in the Tamil Nadu State, India. Three of the major tribal communities in the Nilgiris Hills, Kolli hills and the Kalvarayan Hills were taken for the study. The key informant method was followed and 80 informants were selected to collect the primary data. An exhaustive list of the available NWFPs was also inventorised. The contribution of the livelihood through the products ranged from 50-10 % based upon the collection and marketing of the products.
Techno-performance of laser land leveller under various cultivation methods with suitable weed management regimes on growth of rice
Agriculture land levelling plays a key role because undulating topography of the fields has a major impact on the germination, water movement, water saving, weed growth and crop yields. Management of critical components such as land, water and weeds in agriculture has become a challenging task for many reasons. In rainfed and irrigated agriculture, land development plays a key role because of undulating topography of the soil surface. The study was conducted during Kharif 2021 to evaluate the performance of laser land leveller with various cultivation methods and weed management practices in rice at Tamil Nadu Agricultural University, Tamil Nadu, India. Plant height, number of tillers hill-1, Dry matter production were found to be higher in machine transplanted rice compared to conventional transplanting among cultivation methods. Amidst weed management practices Pyrazosulfuron + Pretilachlor (10 kg/ha) as pre emergence at 3 DAS/DAT fb Bispyripac sodium (25 g a.i/ha) as early post emergence application at 15 DAS/DAT over unweeded control. The results from this study confirmed that, machine transplanted rice with application of herbicide, Pyrazosulfuron + Pretilachlor (10 kg/ha) as pre emergence at 3 DAS/DAT fb Bispyripac sodium (25 g a.i/ha) as early post emergence application at 15 DAS/DAT in laser levelled land had better crop stand and growth thus resulting in lesser weed infestations.
Studies on organic weed management practices in Chickpea (Cicer arietinum L.) under sub tropical agro climatic conditions of Union Territory of Jammu and Kashmir
A field experiment was conducted at the Organic Farming Research Centre, SKUAST-Jammu, Chatha during the Rabi season of 2019-20 and 2020-21 to study the effect of various organic weed management on weed density, yield attributes and yield of Chickpea under sub tropical agro climatic conditions of Union Territory of Jammu and Kashmir. The experiment comprised of 10 treatments consisting of Weedy Check, Weed Free, Hand weeding at 20 DAS, Hand weeding at 20 DAS and 40 DAS, Mulching with rice straw @ 4t ha-1, Mulching with rice straw @ 4t ha-1 + Hand weeding at 20 DAS, Mustard seed meal @ 2t ha-1, Mustard seed meal @ 2t ha-1 + Hand weeding at 20 DAS, Wheel hoeing at 20 DAS and 40 DAS and Hand weeding at 20 DAS + Wheel hoeing at 40 DAS, and were arranged in a randomized block design with three replications. The dominant average weed flora observed in the Chickpea crop during two years of field experiment were Phalaris minor, Melilotus indica, Anagallis arvensis, Chenopodium album and Medicago denticulate etc coinciding from 30-120 DAS of crop. The application of mulching with rice straw @ 4t ha-1 + Hand weeding at 20 DAS controlled the grassy weeds significantly during both the crop growth season than weedy check. Mulching with rice straw @ 4t ha-1 + Hand weeding at 20 DAS not only reduced the total weed population, dry weight but also increased the weed control efficiency significantly over weedy check and other treatments during both the crop growth season. The highest grain yield of chickpea was recorded with weed free (29.80qha-1) which was statistically at par with Mulching with rice straw @ 4t ha-1 + Hand weeding at 20 DAS (29.20q ha-1). However, highest benefit cost ratio was recorded with mulching with rice straw @ 4t ha-1 + Hand weeding at 20 DAS (2.16).
Improved Fertigation Doses of Nitrogen, Phosphorus, Potassium and Sulphur in Garlic (Allium sativum L.) to Enhance Postharvest Soil Nutrient Status
The field experiments were conducted during the two consecutive rabi seasons 2018-19 and 2019-20 at farmer’s field in Dhariyakhedi village of Mandsaur district of Madhya Pradesh to assess the post-harvest status of soil nitrogen, phosphorous and potassium as influenced by different irrigation and fertilizer levels in drip fertigated garlic. The experiment consists of three levels of irrigation water i.e., IW/CPE ratio 0.60 (I1), 0.80 (I2), 1.00 (I3) and three levels of recommended doses of fertilizer i.e., 60% (F1), 80% (F2), and 100% (F3) for garlic crop. The initial fertility status of soil at experimental site with regard to nitrogen, phosphorus (P2O5), potassium (K2O) and sulphur were recorded as 260 kg/ha, 21.5 kg/ha, 380 kg/ha and 19.2 kg/ha respectively. Most of the crop growth and quality parameters viz., plant height, polar diameter, equatorial diameter, fresh weight and dry weight of garlic bulb were significantly influenced by different irrigation and fertigation treatments. Among different irrigation and fertigation levels, the treatment I3F3 recorded highest FUE (64.47 kg/kg), marketable bulb yield (147.43 q/ha) and B:C ratio (5.63). The drip fertigation treatment with IW/CPE ratio 1.0 and fertigation at a rate of 100:50:50:50 kg/ha (N:P:K:S) resulted in higher post-harvest status of soil with regard to nitrogen (275.29 kg/ha), phosphorus (24.52 kg/ha), potassium (402.54 kg/ha) and sulphur (21.37 kg/ha) content.
