Bio management of Root Knot Nematode (Meloidogyne incognita) Infecting Tomato under Precision Farming System
The intention for this experiment is to investigate on standard module for the management of root knot nematode, Meloidogyne incognita infected with tomato. The highest reduction in soil and root population (241.26 and 212.38) of root knot nematode, M. incognita was observed in P. lilacinus (root dip) +T. viride (2 kg/ha) + Marigold intercrop treated plot at time of harvest. The control plot which was found to be maximum population of nematodes in soil and root respectively 1252.54 and 1224.88. Significant reduction in root knot index was observed in the treatment with P. lilacinus (root dip) + T. viride (2 kg/ha)+ Marigold intercropped plot was recorded 1.2 per cent. The roots in untreated control recorded the highest lesion index of 5.00.
Effect of drought on Cotton Genotypes under field condition
The cotton grow in drought condition is a matter of interest to research workers due to in short supply of water to cotton grow in area to area and a solemn problem in rainfed cotton growing area. The field experiment was laid down that the twenty genotypes grown in randomized block design with three replications during Kharif season of 2016-17 and 2017-18. The investigations gained on effect of drought on cotton genotypes parameters viz., plant height, monopodia, sympodia, dry matter production and seed cotton yield were recorded under field condition. In the investigations what could wondering possibility to maximum 137.33cm, 2.54 and 111.91g in TSH-324 and RHC-1217, plant height, monopodiaplant-1and dry matter production, while the minimum 79.66cm, 0.21 and 83.73g in JK-4, AR-9108 and L-799, noticed in the genotype. Apart from this, maximum number of sympodia plant-1(26.43) and seed cotton yield 1803.35 kg ha-1 recorded in the genotype JK-4 while the minimum number of sympodia per plant and seed cotton yield recorded in the genotype L-1384 that were 19.96 and 742.14 kg/ha respectively. The genotype JK-4 is statistically significant superior over rest genotypes. From this investigation, JK-4 genotype is suitable to cultivate in Malwa-Nimar region under drought condition in respect to seed cotton yield.
Molecular identity and clue regarding age of adult for field release of a native larval parasitoid of fall armyworm, Spodoptera frugiperda (Smith)
From Sabour location of Bhalpur, Bihar, India, more than 100 fall armyworm (FAW) caterpillars were collected from the maize field for the emergence of larval parasitoid/s at insect raring facility of Department of Entomology, BAU, Sabour during 2021 but no emerged out parasitoids were found from those. Consequent upon that, few FAW caterpillars were exposed to a pair of braconid wasps which were available with the Corcyra culture in the laboratory it was noticed that the exposed caterpillars were paralyzed and parasitized by the female of that braconid. The identity of the used pair at that time was not known. After observing the acceptance of FAW by those, the emerged out adults of the braconids were further used for its molecular characterization to know its identity which revealed that braconid wasp was actually Habrobracon hebetor Say. From the state of Bihar, this is the first report regarding native larval parasitoid associated with FAW. This larval parasitoid preferred mainly the thoracic sternum of FAW for deposition of eggs. Freshly emerged adults of H. hebetor were sexed and kept separately inside glass vials and were released inside a vial having full grown FAW caterpillars as per their age of 24 hous, 48 hours, 72 hours, 96 hours, 120 hours and 144 hours. Considering the parameters like number of eggs, larvae, cocoons and number of adult wasps as well as sex ratio, it is inferred that as the adults of H. hebetor at 96 hours after emergence produced maximum number of eggs, cocoons and total number of adults (that too having desirable sex ratio) in the laboratory condition, the release of H. hebetor adults in the field should be after 3 days of emergence for maximum suppression of FAW and ‘on filed multiplication’. However, this finding requires further validation by conducting such field experiments.
EFFECT OF DIFFERENT CROPPING SYSTEMS ON SOIL CHEMICAL PROPERTIES DURING DIFFERENT SEASONS IN THE INTENSIVELY CULTIVATED SOILS OF THANJAVUR DISTRICT, TAMIL NADU, INDIA
An experiment was conducted with ten different rice-based cropping systems T1 – Rice-rice-blackgram; T2 – Rice-rice-sesame; T3 – Dhaincha-rice+dhaincha(5:1)-blackgram; T4 – Sunn hemp-rice+dhaincha-greengram; T5 – Blackgram-rice-groundnut; T6 – Greengram-rice-sesame; T7 – Fodder cowpea-rice-fodder maize; T8 – Fodder sorghum-rice-fodder cowpea; T9 – Maize hybrid-rice-bhendi+blackgram; T10 – Ragi-rice-cluster bean+blackgram during different seasons (kharif, rabi and summer), 2021-2022 in the intensively cultivated sandy loam soils of Thanjavur district, Tamil Nadu, India. Samples were collected from different cropping systems in the experimental plot at post-harvest stage during kharif, rabi and summer seasons. Soil samples were examined and analysed for soil chemical properties in the Department of Soil Science and Agricultural Chemistry, Coimbatore, Tamil Nadu, India. Results from the study revealed that highest values of chemical properties like available N, P, K, Ca, Mg, Cu, Mn, Zn and Fe were recorded under T4-Sunn hemp-rice+dhaincha (10:1)-greengram system. Also better soil quality maintenance was observed in T4-Sunn hemp-rice+dhaincha (10:1)-greengram cropping system by recording the highest level of soil available nutrients due to the inclusion of green manure and pulse crops in rice-based cropping systems.
Studies on effectiveness, efficiency of gamma rays, EMS and their combination in M2 generation of Him Palam Hara Soya 1 variety of soybean [Glycine max (L.) Merrill]
Genetic improvement of soybean is needed to increase its production. Mutation breeding is the highly useful and vital technology for soybean improvement. Selection of effective and efficient mutagens are very essential to recover high frequency of desirable mutants. In order to provide genetic diversity and resources for identifying important genes, physical treatment of gamma rays, chemical treatment of ethyl methane sulfonate (EMS) and their combination dose was used to mutagenize soybean variety Him Palam Hara Soya 1 (Himso-1685). The seeds were treated with physical mutagens i.e. gamma rays at five different doses (100 Gy, 200 Gy, 300 Gy, 400 Gy and 500 Gy) at BARC, Trombay, Maharashtra, EMS at 0.5%, 1.0 % and their combination was in the Department of Genetics and Plant Breeding, CSK HPKV, Palampur, H.P during year 2019. A total of 256 M1 individuals were produced from 6,800 treated seeds. Five types of mutants based on phenotypic appearance were identified viz., dwarf plants in comparison to tall plants of control, white flower as compared to purple flower, of control, brown fawn colour on pods as compared to gray fawn colour on pods of control, reduced seed size as compared to bold seed size of control and complete resistant plants prevailing white flowers as compared to purple colour of control were observed in the present study. Gamma rays were found to be more effective as compared to chemical and combined dose to induce vital mutations in variety Himso-1685. Higher the dose or concentration, more reduction in the expressivity of the traits was observed. Beneficial traits from these mutants can be exploited for future soybean breeding programs. This variety Himso-1685 can also be used for discovering novel mutant alleles and functional gene expression analysis using reverse genetics tools such as Tilling.
