Missing data is an obligatory phenomenon in most of the sample surveys and when it not handled cautiously at beginning study, outcomes may result to substantial biases survey estimates. Retaining such evidences into cognizance, this paper proffers few possible improved imputation methods figure out problem missing starting study computation procedure population mean using simple random sampling. The characteristics proffered are ascertained till first order approximation pursued by a...

The essence of this paper is to propose some efficient combined and separate classes estimators for estimating population mean Y¯ under stratified simple random sampling. bias square error the proposed are obtained. theoretically justified over conventional estimator, classical ratio regression estimators, Kadilar Cingi Shabbir Gupta Singh Vishwakarma Koyuncu Solanki Yadav et al. estimator Shahzad estimator. theoretical findings extended with a simulation study accomplished artificially...

This article establishes some improved classes of difference and ratio type estimators population mean study variable using information on auxiliary attribute under stratified simple random sampling. The usual estimator, classical product estimator regression are identified as particular cases the proposed for different values characterising scalars. expression square error suggested has been studied up to first order approximation their effective performances likened with respect...

This manuscript considers some improved combined and separate classes of estimators population mean using bivariate auxiliary information under stratified simple random sampling. The expressions bias square error the proposed are determined to first order approximation. It is exhibited that particular conditions, dominate existing prominent estimators. theoretical findings supported by a simulation study performed over hypothetically generated population.

Deterministic flow models, such as rectified flows, offer a general framework for learning deterministic transport map between two distributions, realized the vector field an ordinary differential equation (ODE). However, they are sensitive to model estimation and discretization errors do not permit different samples conditioned on intermediate state, limiting their application. We present method turn underlying ODE of models into family stochastic equations (SDEs) that have same marginal...

Radish is one of the well-known root crop and its popularity could be due to wider climatic adaptation, easy cultivation method a range uses. Excessive chemical fertilizer lead toxicity in affected growth yield radish. A field experiment was assessed conducted randomized block design with five treatment three replications setup T1 –Without manuring,T2-FYM @5Tha-1 +Vermicompost@ 1.75Tha-1+ jeevamrit@5%conc, T3-FYM@5Tha-1+vermicompost@1.75Tha-1 +jeevamrit@ 10%conc, T4-FYM @2.5Tha-1...

The present study revealed that fecundity of tobacco aphid, Myzus nicotianae Blackman was highest on Lanka type (37.8 ± 7.5) and lowest Nicotiana rustica (7.0±2.5). Chrysoperla carnea consumed 71.20 aphids/larva Flue cured Virginia 58 aphids Burley type. Highest per cent pupation observed Beedi (88%). Fecundity the when it fed cigar wrapper (291 eggs/female), followed by (287 eggs/female). (114 eggs) aromatic were consumed. Corcyra eggs least (220 eggs). FCV most favored for oviposition (25...

A multilocation field experiment was conducted during kharif season (July–September) of 2019 in mungbean under organic nutrient management at Agriculture Research Sub-Station, Sumerpur, Pali and Adaptive Trial Centre, Pali, Rajasthan, India. The nine practices viz. T1- Farmyard manure (FYM) as per soil health card @ 10 t ha-1, T2- Vermicompost 2 T3- T1+Vermiwash 10% 15, 30 45 days after sowing (DAS), T4- T2+Vermiwash DAS, T5- T1+Panchgavya 4% T6- T2+Panchgavya T7- 6% T8- DAS T9- Control...

Chrysoperta carnea (Stephens) is considered as an important predator against Helicoverpa armigera (Hii bner) and other sucking pests. The behavioural response of adult C. to the volatiles plants infested by H. was studied under laboratory conditions through electroantennogram olfactometer. adults showed good from flowers bolls cotton . Highest noticed tbe than leaves. In zone resident period studies, spent distinctively more time in 6 (nearest source) when were tested. dual choice methods,...

A field experiment was conducted at Horticulture Farm, S.K.N.College of Agriculture, Jobner (Jaipur) during Rabi season 2016-17 and 2017-2018.The consisting four bio-fertilizers (control, Azotobacter, PGPR (Pseudomonas) Azotobacter + five bio-regulators Thiourea @ 500 ppm, 1000 salicylic acid 100 ppm mepiquat chloride ppm).The total 20 treatment combinations were tested in split-plot design with three replications.Application biofertilizers: also significantly increased the neck thickness,...

Aqueous extracts of Medicago denticulata, Melilotus indica and Chenopodium album at 5%, 7.5% 10% significantly reduced plant population Phalaris minor under laboratory shade house conditions, thus, indicating the inhibitory role allelo-chemicals from these weeds. Under seed germination relative ratio was affected more than wheat with highest reduction in aqueous extract indica, followed by album. came to be best concentration that optimally maintained population. In tray experiment recorded...

Abstract The present investigation dealt with the effect of two granular systemic nematicides aldicarb and carbofuran, individually in combination 100 mg · 1 ‐1 GA 3 , on plant growth root knot formation C. frutescens var. California Wonder. Both were applied as a seed‐dip treatment. increased seed germination seedling growth. All concentrations (2 to 20 g a.i. ) when independently, reduced length epicotyl hypocotyl. However, application these showed antagonistic behaviour. treated seedlings...

The chrysopid, Mallada astur (Banks), recorded for the first time as promising egg and early larval predator of O. arenosella in interior Karnataka was evaluated its predatory efficiency. This is predominant on coconut palmyrah palms 30m height. Its short life cycle (24.5 days) a combined diet eggs larvae , high fecundity per female (mean=102.3 eggs), ability to thrive galleries strongly support utilization biocontrol agent during peak period infestation (September-February) Karnataka.
