Effect of ambient and modified atmospheric storage on viability and vigour of ground nut seeds stored as pod and kernel
Seed viability and seed vigour are the most important factors affected during deterioration. However, viability and vigour are not affected at the same rate. In the present study attempt was made to assess the pattern of loss of vigour and viability of two groundnut varieties (CO 7 - Dormant variety and TMV 13 non dormant variety) when stored as kernel and pod in different storage environment viz. ambient storage, cold storage and atmosphere with 40% of CO2 concentration. The groundnut kernels were dried to 8 % moisture content with the care of not over drying and gradual reduction of moisture. Ten kg of ground nut kernel and pods (untreated), were packed in gunny bag (farmers practice - Moisture vapour pervious) and 700 gauge polyethylene container (Moisture vapour proof) and placed in ambient condition and also in cold storage (100 C + 40 % RH) with three replications. The same were kept in a container were 40 % CO2 concentration was maintained throughout the study period. The CO2 concentration was measured and maintained on weekly basis. The results in the present study revealed that the pattern of vigour and viability loss was found to endorse the already established trend of decline in vigour and viability i.e., the decline in vigour occurs much more rapidly than the decline in viability. At the same time, the pattern of loss in vigour and vibility varies with the different patterns of seed handling in storage. Pods packed in 700 gauge polyethylene bag and stored at 10 0 C + 40 % RH (storage environment) maintains better vigour and viablity for 12 months, 1224 and 76 % in TMV 13 and 1158 and 72% in CO7 respectively, compared to gunny bag storage under ambient condition, where a vigour and viability of 858 and 43 % in TMV 13 and 664 and 47 % in CO 6 was recorded. Kernels stored in 100 C in polyethylene bag was on par with pods stored in cold storage. After 12 months of storage it recorded a vigour and viability of 1218 and 75 % in TMV 13 and 1210 and 76 in CO7, respectively. The storage insect - Ground nut seed borer (Carydon seratus) - was observed under ambient storage alone, that too only in TMV 13 but not in CO7. The seeds and pods stored in a storage atmosphere comprising of 40 % of CO2 concentration maintained a vigour and viability 1220 and 81 % in TMV 7 and 1196 and 78 % in CO7, respectively after 12 months of storage, which was an par with kernel or pod storage in cold storage. Hence storing the pods or kernels of groundnut dried to the moisture content of 8 percent and stored either in the storage environment of 100 C + 40 % RH or 40 % CO2 concentration can maintain the vigour and viability as per the Indian Minimum Seed Certification Standards upto 12 months of storage.
Effect of Physical and Physiological seed Quality in Groundnut Varieties under Different Storage Conditions
The freshly harvested groundnut pods of different varieties viz., VRI 2, VRI 6, VRI 7, VRI 8, CO 6, CO 7 TMV 7 and TMV 13 were collected and dried to 9% moisture content, packed in cloth bag without any pod treatment and stored under cold (4 ± 2°C) and ambient storage condition (28 ± 2°C). The seeds were evaluated for the seed quality characters at monthly interval upto 12 months revealed that the varieties VRI 7 and TMV 13 showed higher germination than other varieties irrespective of storage condition. With reference to the storage conditions, seeds stored in cold conditions recorded higher germination than the ambient condition stored seeds irrespective of varieties.
Traditional bio-amendments and agrotechnology improves productivity of Tuberose (Polianthes tuberosa L.) in sodic soil condition
Agroecological interventions are imperative for boosting agricultural productivity and soil fertility while increasing profitability of subsistence farmers in low-income countries by replacing synthetic fertilizers. Traditional methods of sustainable farming are an emerging concept for designing the management practices of agriculture which help to assist in proper execution of the task. With this context, the present study was aimed to evaluate the impact of animal manures (cow manure) and plant residue-based organic amendments on soil quality, nutrient uptake and balance yield under sodic condition of Ayodhya. The field experiments were conducted for two years at the above two sites and amendments were done at a rate by replacing chemical fertilizers. Field trials were conducted with the 100% RDF as control, and other treatments with different bioenhancers paired with mulch and non-mulch. The organic amendments were done during stages and the residual effect was observed at the end of the experiment. Though soil organic carbon (SOC) was found to show significant (p ≥ 0.05) increase in cow pat pit amended plots, jeevamrita followed by panchagavya showed year wise increase in both soil organic carbon (SOC) and available nutrients. Plant growth and yield attributes in amended plot slight changes to that of control in the first year but after that amended plot showed better performance in the next year. All amendments resulted in higher benefit: cost ratio except control. Our study advocates that validation of suitable amendment based on organic inputs are imperative for improving the yield, soil quality and nutrient balance.
Analysis on Adoption of recommended banana cultivation technologies among banana growers in Theni District of Tamil Nadu, India
In India banana ranks first in production and third in area among fruit crops. It accounts for 13% of the total area and 33% of the production of fruits. Production is highest in Maharashtra (3924.1 thousand tones) followed by Tamil Nadu (3543.8 thousand tonnes). Within India, Maharashtra has the highest productivity of 65.70 metric tones/ha against national average of 30.5 tonnes/ha. Mango and Banana are the leading fruit crops in Tamil Nadu accounting for over 81% of the total fruit production. Hence, the present study was undertaken with the following objective to study the Knowledge and Adoption level of recommended banana cultivation technologies among banana growers with a sample size of 120 farmers. The respondents were selected based on purposive random sampling method. The data were collected from each respondent through pre-tested interview schedule. The results of the study revealed that high level of knowledge regarding selected practices of banana production technologies like Drip Irrigation (95.83%), Desuckering (92.50%), Pre-treatment of suckers (86.67%), Fertigation (91.67 %), Propping (84.16%), Bunch cover (60.00%), Ratoon crop (98.33%), Use of Growth Regulators (61.67%), Micronutrients (67.50%), Intercropping at earlier stages (70.83 %). The high level of adoption by the banana growers was reported in practices like Drip Irrigation (92.50%), selection of varieties (81.60%), time of harvesting (82.50%), Fertigation (87.50%), Pre-treatment of suckers (82.50%), Desuckering (78.33%), Intercropping at earlier stages (66.66%).
EFFICACY OF NEWER INSECTICIDE MOLECULES AGAINST DIAMOND BACK MOTH IN CABBAGE AT TEMPERATE REGION
Four field trials of two season studies in two different geographical locations were conducted in the temperate region of Nilgiri District, Tamil Nadu, India. Results revealed that, chlorantraniliprole 18.5 SC @ 10 g a.i. ha-1 and emamectin benzoate 5 SG @ 10 g a.i. ha-1 treated plots were observed more than 90 percent reduction of P. xylostella larval population after two rounds after spray and recorded relatively safer to spider population when compared to other test insecticides. Based on per cent reduction in population of P. xylostella over untreated control, the order of relative efficacy of different insecticidal were, chlorantraniliprole 18.5SC @ 10 g a.i. ha-1 = emamectin benzoate 5SG @ 10 g a.i. ha-1 > indoxacarb 14.5SC @ 40 g a.i. ha-1 = novaluron 10EC @ 75 g a.i. ha-1 = chlorfenapyr 10 SC @ 75 g a.i. ha-1 > thiodicarb 75WP @ 750 g a.i. ha-1 = fipronil 80 WG @ 75 g a.i. ha-1 > chlorpyrifos 20 EC @ 400 g a.i. ha-1. A reduction in the population of spiders in chlorantraniliprole 18.5 SC @ 10 g a.i. ha-1 and emamectin benzoate 5SG @ 10 g a.i. ha-1 treated plots were observed immediately after the application of insecticides. Though there was a sudden decline in the population, it started increasing gradually. Hence, chlorantraniliprole 18.5 SC @ 10 g a.i. ha-1 and emamectin benzoate 5SG @ 10 g a.i. ha-1 will be recommended for the management of P. xylostella in cabbage ecosystem in temperate regions.
