A study on Foreign Matters Analysis in lint grade of some Egyptian Cotton Varieties and their Effect on Fiber and yarn Quality
This study was carried out to investigate the effect of the cleaning process (cleaning and without cleaning) and lint grades six grades (G/FG, G, FGF/ G, FGF, GF/FGF and GF) on fiber quality (upper half mean length m.m.), uniformity index% fiber strength g/Tex and micronair value and yarn quality – C. V%-) of some extra-long-staple cotton varieties (Giza 93, Giza87, Giza92, Giza96, and Giza88) and some long-staple cotton verities (Giza86, giza94, giza97, giza90 and Giza 95) and their interaction. Results indicated that the difference between cleaning treatments’ upper half mean length (m.m), uniformity index%, fiber strength (g/Tex), Micronair, yarn strength, and yarn and yarn evenness (C.V%) were significant at all varieties of extra-long staple. Results showed that differences between lint grades six were significant. G/FG and G grades gave the best values for all studied traits, and GF gave the worst values for all these traits. Also, results indicated that the differences between verities were significant for all studied traits. The interaction between the cleaning process and verities on yarn strength and yarn evenness (C.V%) was significant.
EVALUATION OF THE EFFICACY OF NEW HERBICIDE FOR CONTROL OF BROADLEAVED WEEDS IN WHEAT UNDER MID HILL CONDITIONS OF HIMACHAL PRADESH
Due to the absence of effective management techniques, weed infestation is one of the main biotic factors affecting wheat output and productivity. Herbicides are a crucial part of agricultural production systems because they are the quickest, cheapest, and most effective way to control weeds. Decrease in the use of herbicides without compromising yields can save production costs and environmental damage. Evaluation of herbicides and their mixtures were studied at the experimental farm of the Department of Agronomy, CSK HPKV, Palampur, to control the broad-leaf weed infestation in wheat. Findings exhibit that among the different herbicide treatments tested Halauxifen methyl Ester + Florasulam + Polyglycol recorded significantly higher growth and yield attributes of wheat which was statistically at par with Halauxifen-methyl + florasulam + carfentrazone + surfactant treatment while significantly lower growth and yield attributes of wheat was recorded in weedy check treatment. Higher yield (straw and grain) and weed control efficiency of wheat was recorded in Halauxifen-methyl + florasulam + carfentrazone + surfactant treatment while lower grain yield, straw yield and weed control efficiency was recorded in weedy check. Hence, highest gross returns (134.3 × 103 INR ha-1), net returns (91.4 × 103 INR ha-1) and B: C ratio (2.13) were obtained from Halauxifen-methyl + florasulam + carfentrazone + surfactant 10.21 + 20 g a.i. ha 1 treatment.
Information on Non-coding RNAs in the alleviation of biotic stress in rice
Rice is the major staple food crop across the globe. Rice productivity is hindered by several biotic and abiotic stresses, which cause serious damage to plant growth and yield losses. Understanding the regulatory molecular events and their biological mechanisms, which are interconnected through the molecular interaction process to minimize the yield losses caused by the occurrence of stress factors, is of great importance. In this study, the data on experimentally curated stress-responsive miRNAs and lncRNAs in rice were collected from the literature and stored in a database. The chromosome map, bipartite network, and blast options were developed for miRNA. The basic features of miRNA (402) and LncRNA (4,543) include miRNA, miRNA ID, position, chromosome no, sequence, regulation, and protein function. For LncRNA, gene ID, chromosome number, gene regulation strands for abiotic stress and transcript ID, chromosome number, gene regulation strands for biotic stress, chromoMap network, and blast options were included in the database.The database can be efficiently used for genetic engineering experiments such as the development of CRISPR/cas9 construct and generation of transgenic plants and also for molecular breeding, which would facilitate the development of high-yielding rice varieties with broad-spectrum biotic and abiotic stress tolerance.
Assessing the Carbon Sequestration and Oxygen Release Potential of Trees and Shrubs under High Density Plantation
Mixed tree plantations can be a good silvicultural alternative for climate change mitigation. The carbon sequestration estimated in trees and shrubs from the previous study indicated that there are certain tree species with high ability to fix atmospheric carbon dioxide into tree biomass. In order to understand how carbon storage and allocation patterns vary among different plantation types, the present study was carried out to compare the performance of two different plantation sites (BSA 1: 14 species of 10 families and BSA 2: 14 species including 7 trees and 7 shrubs of 11 families). Based on the results, the highest biomass accumulation was observed in BSA 1(6.82 tonnes of biomass per ha per year) and the lowest mean biomass production was observed in BSA 2 (3.10 tonnes of biomass per ha per year). Likewise, the highest total carbon sequestration and oxygen release potential was recorded in BSA 1 (4.26 tonnes of carbon per ha per year, 11.36 tonnes of oxygen per ha per year). The results revealed that out of two study areas studied, the experimental site with tree species showed better performance when compared to the site planted with trees and shrubs. Azadirachta indica, Thespesia populnea, Pongamia pinnata and Terminalia catappa were the tree species that contribute for high carbon sequestration in the BSA 1. The present study suggest that selection of correct choice of tree species for plantation would enhance more carbon sequestration, high oxygen release and improved environmental quality.
Alleviation of physiological and biochemical attributes of rice cultivars by protectants under ozone stress
Elevated levels of tropospheric ozone (O3) can harm plants by inhibiting growth and production thereby posing a threat to environmental health and food security. As a consequence, developing novel strategies for crop protection against ozone has become critical. Ethylene diurea (EDU), is one of the most effective protectants, frequently utilised in various studies; nevertheless, the efficacy of other protectants is yet unknown. As a result, the purpose of this study is to evaluate the efficacy of EDU, neem coated urea (NCU), and ascorbic acid (AsA) in reducing ozone stress (100 ppb) in ozone tolerant (Anna (R) 4) and sensitive rice cultivar (TRY (R) 2) grown in an open top chamber. The results show that applying protectants was extremely beneficial in enhancing physiological characteristics and lowering malondialdehyde and proline levels in both rice cultivars, with the impact being significantly greater in TRY (R) 2 than in Anna (R) 2. The addition of 1% NCU increased the photosynthetic rate in Anna (R) 4 by 23.80 and 54.78%, respectively. In ozone tolerant and sensitive cultivar, the photosynthetic rate (20.15 and 50.21%), stomatal conductance (15.78 and 37.14%), and chlorophyll content (36.63 and 60.72%) were all increased by 1% AsA treatment. Moreover, in O3 sensitive cultivar, application of 1% NCU and AsA reduced MDA by 35.63 and 31.41%, and proline by 40.8 and 36.64% respectively. To conclude, the current study revealed that besides EDU, NCU and AsA are also superior in terms of protecting the plants from ozone stress.
