Data was obtained from forty farmers using structured questionnaire and the input-output relation of groundnut production via Cobb-Douglas production function was examined in this study. It was found that the sum of elasticities was 0.73. The result of the t’ test proved that in groundnut farms S b<sub>i&nbsp; </sub>was less than one, it indicates decreasing returns to scale, which indicates some of the inputs are excessively used. The production elasticities for human labour, bullock labour, machine labour charges, seed cost and pesticides were positive and significant where as farm yard manure and fertilizers cost was negative which showed that increase in these costs result in decrease in output. The MVP of selected input variables were estimated to be 25.08, 4.21, 6.74, 1.87, 17.34, -19.46 and -7.67 showing that FYM and fertilizers are over utilized and the rest of the variables are underutilized. The groundnut production in the study area would be profitable.</p> I. Shakuntala Devi, K. Suhasini, G. P.

The arils extracted from the fruits were dehydrated in a solar tunnel (30-45°C) drier to prepare value added product <em>Anardana.</em> The developed product was packed in three different packaging materials <em>viz</em>. gunny bags, aluminium laminated pouches (ALP) and aluminium laminated pouches with vacuum (ALPV) and stored under ambient and refrigerated temperature for a period of 12 months so as to evaluate overall effect of storage period, storage condition and packaging material. After 12 months of storage period, higher retention of various quality characteristics like TSS, titratable acidity, ascorbic acid, total sugars, anthocyanins content, sensory characteristic scores with less increase in moisture content, NEB (non-enzymatic browning),HMF (hydroxymethyl furfural) and furfural content was observed in <em>Anardana </em>packed in ALPV followed by ALP and gunny bags. The changes in the quality characteristics of the <em>Anardana</em> were slower in refrigerated storage conditions as compared to ambient conditions.</p> Abhimanyu Thakur, N. S.

A pot experiment with twenty-four treatment combinations was setup in the net house. The treatment combination consisted of 4 levels of P: P<sub>0</sub>- 0, P<sub>50 </sub>- 237.5 kg ha<sup>-1 </sup>SSP, P<sub>75 </sub>- 355.5 kg ha<sup>-1</sup> SSP and P<sub>100</sub>- 475 kg ha<sup>-1</sup> SSP, 3 levels of Zn: Zn<sub>50</sub>- 5 Kg ha<sup>-1</sup> ZnSO<sub>4</sub>, Zn<sub>75</sub>-7.5 Kg ha<sup>-1</sup> ZnSO<sub>4</sub>, Zn<sub>100</sub>- 10 Kg ha<sup>-1</sup> ZnSO<sub>4</sub> and 2 levels of AM: I<sub>0</sub>- 0 and I<sub>15</sub>- 15 g per pot. The main objective of the study was to reduce the antagonistic interaction between P and Zn by using AM fungi. The results of combined effects of application of P, Zn and AM revealed that P, Zn addition along with AM fungi improved plant growth parameters, plant nutrient content and total nutrient uptake (both above ground and underground portion) of the plant. The results indicated increase in plant height, root length and total nutrient uptake by increasing the level of P, Zn and Arbuscular Mycorrhizae. Also, Arbuscular Mycorrhizae enhanced plant growth by reducing Phosphorus or Zinc deficiency. Antagonistic effects of P and Zn addition on plant nutrient content and total nutrient uptake were absent due to application of AM fungi. Our results indicated that by using appropriate levels of AM fungi along with P and Zn, antagonistic interactions can be reduced for maximizing the plant nutrient content and nutrient uptake which may lead to improvement in plant growth and nutrition.</p> Gitika Bhardwaj, Uday Sharma, Perminder Singh Brar, Rajesh Kaushal ##submission.copyrightStatement## http://journalcjast.com/index.php/CJAST/article/view/30675 Wed, 03 Jun 2020 00:00:00 +0000 Relative Abundance and Foraging Behaviour of Pollinator Fauna on Niger (Guizotia abyssinica Cass.) and its Influence on Yield http://journalcjast.com/index.php/CJAST/article/view/30677 <p>Niger (<em>Guizotia abyssinica</em> Cass.) is one of the important oilseed crop of Southern and Central India. Niger is a completely cross pollinated crop brought about by insects, referring to the importance of pollination, the study was undertaken to know the role of pollinators in Niger ecosystem and its influence on yield parameters. The present investigation was carried out during 2016-2017 at the Zonal Agricultural Research Station, Gandhi Krishi Vignana Kendra (GKVK), University of Agricultural Sciences, Bangalore, India. In this study, fourteen species of flower visitors were observed during the flowering period belonged to orders Hymenoptera (9 species), Lepidoptera (4 species) and Diptera (1 species). The overall diversity of pollinators was more during morning hours (8.00 AM to 11.00 AM) and gradually decreased after 12.00 PM to 5.00 PM. Among different pollinator species <em>Apis florea</em> was more abundant with 41.46% followed by <em>Apis dorsata</em> and <em>Apis cerana</em>. The peak activity of <em>A. florea</em> was observed at 11.00 AM followed by <em>A. cerana</em> at 10.00-11.00 AM <em>and A. dorsata</em> was at 11.00 AM. The highest number of probing was observed in <em>A. florea</em> (7.52) followed by <em>A cerena</em> and <em>A. dorsata</em>. The time (sec) taken for one probing was highest in <em>A. florea</em> followed by <em>A cerena</em> and <em>A. dorsata</em>. The number of filled seeds observed 37.66% less in caged condition when compare with open pollination and there was significant decrease in the yield in caged condition when compare with open pollination indicating importance of pollinators specifically honey bees for successful production of Niger.</p> .

The experiment was laid out in Randomized Block Design with three replications. The observations were recorded for 11 characters. Variances due to testers were greater than variances due to lines for most of the characters. The estimates of General Combining Ability (GCA) effect indicated that PB71, BB85, PB66, Swarn Syamli and DBL02 were best general combiner for earliness (days to 50% flowering), whereas the best specific cross was BRLVAR6 × DBL02. For weight of marketable fruits per plant PB66, SMB115, LC7, BRLVAR6 were best general combiners and SMB115 × DBL02, PB66 × Pant Samrat and IBWL 2001-1 × Pant Rituraj were best specific combiners. Pant Rituraj was found best general combining effect for plant height, fruit diameter, weight of marketable fruits per plant, number of unmarketable fruits per plant, total yield per plant and total yield per hectare. Pant Samrat showed good General Combining Ability (GCA) effects for number of primary branches per plant, number of marketable fruits per plant, weight of unmarketable fruits per plant and total number of fruits per plant. DBL02 was recorded best general combiner for earliness and fruit length. SMB115 and PB 66 were best general combiners for most of the yield characters. SMB115 × DBL02, PB66 × Pant Samrat and IBWL2001-1 × Pant Rituraj were showed highest Specific Combining Ability (SCA) effect for most of the characters. Therefore, these cross combinations could be commercially exploited for higher yield.</p> . Pramila, M. L.

Since 2007, high speed engines were introduced in the trawl fishing sector which yielded higher hauling speed compared to the indigenous engines. Munambam fishing harbour is one of the biggest fishing harbours in Kerala where more than 90% of the mechanized trawlers operate with high speed engines. The high-speed trawlers were criticized for their environmental impacts to marine resources in terms of overexploitation and high fuel consumption. The fuel consumption of fishing units has economic, social and environmental implications with regard to sustainable fish harvests and livelihood security of fishermen. The objective of the study was to assess the economic and environmental implications of high speed trawl fishing units in Munambam fishing harbour on the South west coast of India. The data were collected from 90 boat operators from Munambam fishing harbour during the 2017-2018 fishing season. The samples were drawn randomly from the boat owners or boat operators. The results of the multiple regression analysis used to assess the factors affecting fish catches by high speed trawlers indicated that skipper’s experience and fuel consumption had positive and significant influence on fish catch and 1% increase in quantity of fuel used led to an increase of 0.363% in gross income. The carbon dioxide emissions from the trawlers were also estimated to assess the environmental implications.</p> N. Aswathy, R.

However, conflict between farmers and <em>Nilgai</em> due to its habitat loss and the increased damage to the crops by this wild species in the agricultural lands. Present paper deals with the study conducted on the population structure, size group and abundance of Nilgai inhabiting Shahabad region in Dumraon (Buxar) Bihar, India from January, 2014 to December, 2015. Survey was performed in the morning to evening time on the specific days by motorcycle and walking, where, there was no local footpath due to difficult, undulated study area. The direct methods utilized sighting of animals carefully from a close distance and behavior of the animal were observed. During the course of study 07 herds with total 407 numbers of Nilgai were counted through direct sighting with from closed distance. The density of Nilgai was found under 431.10 acre are as covered in Haryana Cattle Breeding Farm (HCBF) and its surrounding in Dumraon. The sex ratio of Nilgai with age group structure of the population was represented in percentage. Female biased adult male, ratio was found 1:3. While overall sex ratio was found 14.25% male, 38.57% female, 9.58% semi adult male, 20.15% semi adult female, and 18.46% calves respectively. Female Nilgai has been observed social like behavior and grazing with juveniles in a group but males were found in scattered form. Nilgai migrate for food towards agricultural land during dusk and return to HCBF with less human activity during dawn. This shows mark migration behavior during summer and rainy season. Some Nilgai migrations were observed for searching food and water during summer from south upward plain region of Dumraon to low-lying north plain area near Bhagar oxbow lake Simri, Chakki and Brahampur.</p> Suday Prasad, D.
