The experiment was conducted during rainy (kharif) seasons of 2023 and 2024 at Tamil Nadu Agricultural University, Coimbatore, to study the application nano DAP using a hybrid drone in groundnut (Arachis hypogaea L.) crops. UAV, model DH-AG-H1, equipped with 12 L sprayer tank 16,000 mAh battery. UAV's performance assessed across multiple parameters, including spray droplet deposition rate, size distribution, density, area coverage, uniformity drift characteristics. UAV operated height 1 m...
Abstract Two rice genotypes, aluminum (Al)‐tolerant Co 37 and Al‐susceptible ADT 36, were evaluated for their physiological responses in the presence of Al stress a hydroculture experiment. levels (0 222 μmol/L) supplied nutrient solution two genotypes subjected to weeks. Root growth parameters, relative reduction roots (RGRR), effects calcium (Ca2+) nitrate metabolism, content roots, pH shift patterns recorded. The treatments had lesser effect on terms root dry matter production as compared...
Aedes mosquito control has gained much importance nowadays in view of rise number reported cases dengue and chikungunya India other countries. In the present study, C21 attracticide (containing a pheromone an insect growth regulator—IGR, developed by Defence Research Development Establishment (DRDE), Gwalior, was tested for its feasibility surveillance multicentric mode from October 2007 to June 2012 urban (Delhi, Bengaluru district, Karnataka) suburban (Alappuzha Kerala) settings country...
Field experiments were conducted at TNAU, Coimbatore during 2019 and2020 for developing organic nutrient package finger millet (Ragi) usingthe variety CO (Ra) 15. Treatments included twelve combinations of weedcompost, enriched vermicompost, farmyard manure (EFYM) as soilapplication along with panchagavya, effective microbes (EM), vermiwash, eggamino acid foliar spray. The experiment was laid out in RBD threereplications. results showed that application vermicompost@ 1t ha-1 applied two...
Fodder cowpea (Vigna ungiculata (L.) Walp.) is regarded as one of the most important leguminous fodders due to its high biomass yield, protein content and rapid growing nature. A study analyze different genetic parameters, trait association diversity was carried out with 79 fodder genotypes. The mean performances genotypes showed wide variation for all traits studied. Plant height, number primary branches, leaves per plant, leaf length, breadth, area index dry matter yield were found have a...
In the current study, general combining ability (GCA) and specific (SCA) studies were carried out in 15 pearl millet hybrids derived from five lines three testers The GCA for parents SCA showed highly significant differences among them. genetic variances revealed pre-dominance of non-additive gene action all traits studied. correlation that namely leaf weight, dry matter yield per plant, stem plant height, to ratio breadth had significantly positive with green fodder plant. Contemplating se...
Background: Blackgram being important crop among pulse is gaining popularity and thus requiring suitable production practices especially under organic farming. In this context, study was proposed with the objective to investigate optimal nutrient management in blackgram by utilizing various sources. Methods: Field experiments were conducted at two different locations spilt plot design. The treatments consisted of 4 levels manure viz., Farm Yard Manure (FYM) @ 12.5 t ha-1, Vermicompost (VC)...
Aim: The experiment was taken up to study the influence of various organic nutrient sources on soil availability and their uptake also quality parameters vegetable cluster bean. Place Duration Study: conducted at irrigated wetland farms, TNAU, Coimbatore during year 2018. Methodology: RBD (randomized complete block design) design adopted replicated thrice. total number treatments were 12 with basal applications manures namely farm yard manure, vermicompost, humic acid, ghanjeevamrutham...
An experiment was conducted to evaluate the genetic divergence in 93 inbreds of fodder maize through variability, D2 and principal component analysis. Observations were recorded on ten biometrical traits a quality trait. The variability analysis revealed higher GCV PCV for green yield per plant heritability coupled with high advance viz., height, leaf length plant. Hence, study indicated that direct selection above would be effective. Diversity sorted into eleven clusters. In case inter...
A field experiment was carried out at farmer’s field, Mudhalipalayam, Coimbatore during kharif 2019 to evaluate the effect of different weed management practices on organic tomato yield and soil microbial population. The laid in a randomized block design with three replication twelve treatments. Microbial count were recorded 30, 60 90 DAT. study revealed that higher population viz., fungi, bacteria actinomycetes under application compost @ 5 t/ha last ploughing + one hand weeding 30 DAT...
Combining ability of the three pistillate lines and eight testers was assessed by Line x .ester analysis. The variance components due to sea were higher than gca for five characters except number nodes upto main spike indicating predominance non- additive gene action. genotypes 262-1 TMV 5 mutant 3 good general combiners. hybrid combinations 240 1, 4 262 1 specific These materials can be profitably utilised in exploitation new hybrids castor.
An experiment was conducted to estimate the lethal concentration of polyploidy inducing chemical Colchicine in two genotypes Bajra Napier hybrid CO 6 and TNCN 1534. Single nodded setts 1534 were treated with colchicine using different methods viz., whole immersion concentrations 0.05%, 0.10%, 0.15%, 0.20% 0.25% for 3 hours cotton swab method same five concentrations. The LC50 values observed based on growth reduction seedlings after planting by methods. sprouting percentage survival both...
Groundnut leaf miner (Aproaerema modicella. D.) is an important feeding insect in groundnut that significantly reduces the pod yield up to 50 per cent. The growth and development of this pest closely associated with abiotic weather parameters prevailing a particular location. Due paucity information available on population dynamics factors, study was undertaken Erode district Tamil Nadu during Summer, 2023. damages were recorded through fixed plots survey adult moth activities monitored...
Background: Traditional organic formulation bijamrith prepared from fresh urine and dung of cow is an important element in natural farming extensively applied modern agriculture practices to improve the soil fertility, control pest disease plants. The scientific validation biologically active compounds unexplored. Methods: Bijamrith was excrements Gir cow. Since, volatile low molecular weight wastes could be derived solvent extract using GC-MS effectively, were separated by liquid-solvent...
