Barnyard millet is one of the hardiest, climate resilient and fast growing crop that is bestowed with high nutrient content in grains. An experiment was carried out in barnyard millet under natural sodic soil condition to study the effect of different methods of crop establishment and to optimize the nutrient requirement for barnyard millet (Kudiraivali) under sodic soil condition using the short duration high yielding variety Co (KV)2 during kharif season in 2016 at Anbil Dharmalingam Agricultural College and Research Institute. The experiment was carried out in FRBD comprising two factors viz., crop establishment techniques like line sowing at 25 x 10 cm (E1) and 35 x 10 cm (E2) and transplanting at 25 x 10 cm (E3) and 35 x 10 cm (E4) and nutrient management practices of N1 at 75 %, N2 100% and N3 125 % recommended dose of fertilizers. The experiment was replicated thrice. Totally twelve treatment combinations were analyzed. Results revealed that transplanting of barnyard millet at 35 x 10 cm with 125 % RDF recorded higher grain yield of 980 kg/ha with increased growth parameters like plant height, number of tillers and yield attributes viz., number of panicles, length of panicle and weight of the panicle in sodic soil.
Pseudomonas fluorescens (Pf1) showed maximum Indole Acetic Acid (54.70 µg ml-1) (IAA), Salicylic Acid (SA) (28.10 µg ml-1) and siderophore production was 9.30 micromoles benzoic acid ml-1. Similarly Pf1 recorded higher amount of HCN with 0.08 (1 unit= 0.001) absorbance. From the above study it reveals that bacterial metabolites may also contribute to the disease resistance. Besides the capacity to colonize roots intensively for an extended period of time. the production of these siderophores has been linked with disease suppressing ability of certain species of fluorescent pseudomonas.
In Cauvery Delta Zone (CDZ) of Tamil Nadu, Sugarcane is an important commercial crop with wider spacing and lond duration which suffers from weeds where weed management studies are vey meagre. Therefore, the present experiment was conducted during the special season of 2016-17 to 2018-19 at Sugarcane Research Station, Sirugamani, Tamil Nadu to evolve suitable weed management practices for weed control in Sugarcane in the CDZ for increasing the cane yield. The experiment was laid out in RBD replicated thrice with 8 treatments using TNAU Sugarcane Si8 as test variety. The treatments consisted of pre emergence herbicides in combination with post emergence herbicides or weeding by power tiller or intercropping with daincha. The crop yield parameters, weed control efficiency and economics were observed. Significantly higher cane yield (123.3 t/ha), highest net income (Rs. 2,11,220/ha) and BCR (3.02) along with highest weed control efficiency (50.4%) at 240th day was recorded with application of Pre-emergence herbicide (atrazine @1.00 kg/ha) and post emergence herbicide (Metribuzin @ 0.75 kg/ha) at 60 days after planting.
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.
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.
