Abstract: For centuries the aloe vera plant has been known for its medicinal properties. It is proposed to be of benefit for the digestive and immune systems, as well as having healing effects on the skin. Chemical constituents of sea buckthorn berries are under research due to positive effect in inflammatory disorders, cancer mechanisms and on bone marrow after chemotherapy.The present study was undertaken to develop a ready to serve (RTS) beverage using Aloe vera gel and sea buckthorn berries. Aloe vera gel (25%), sea buckthorn berry juice (30%), sugar (25%), and citric acid (0.1%) were mixed to prepare the blend with TSS of 130Brix. The product was bottled, pasteurized, and stored at room temperature. The quality characteristics and storage stability of the berry juice aloe gel beverage (BJAB) was compared with berry juice (BJ). Time-dependent analysis was carried out up to four months for various physicochemical parameters, antioxidant profile, microbial quality and sensory acceptability. The BJAB exhibited superior quality characteristics compared to BJ when compared as in fresh condition and in stored samples. The BJ was acceptable up to three months whereas BJAB for four months. The results indicate that nutraceutical rich aloe gel and berry juice can be utilized to develop nutritional and tasty functional fruit beverage with improved quality.

Abstract: The research was conducted to fabricate and develop an advanced solar tunnel dryer (STD) for the drying of fruits, vegetables and medicinal plants. The system was designed as a portable system for decentralized applications at various sites to satisfy the drying requirements of small farmers and co-operatives. The cross sectional area of the solar tunnel dryer was trapezoidal in shape having 0.1225 m2 face area, with length and width of four meters and one and half meter respectively. It comprises a collector section (2 m) long and a drying section (2 m long) and one electric powered fan to provide the required air flow rate over the perishable agricultural products to be dried. Transparent polythene cover was used to close the dryer on top side to maintain the steady state air flow within the dryer. It has been observed that the drying air temperature was easily raised by some 8-14°C above the ambient temperature at air velocity ranges 0-1 ms-1. The process curves were found similar to a conventional dryer showing that this dryer can be successfully utilized for the drying of agricultural products using solar energy.

Abstract: Genetic variability, heritability, genetic advance and its per cent over mean for eighteen characters were assessed by field evaluation of twenty–four wild melon genotypes at College of Horticulture, Bagalkot , Karnataka during 2013-14. High degree of variation was observed for all characters. The difference between phenotypic co–efficient of variation (PCV) and genotypic co–efficient of variation (GCV) are found to be narrow for most of the traits. However, high GCV and PCV was observed for leaf area, number of fruits per vine, average fruit weight, fruit length, fruit breadth, yield per vine, fruit cavity size, number of seeds per fruit, fruit flesh thickness, TSS, vitamin–C and seed to pulp ratio. High heritability coupled with high genetic advance recorded for vine length, leaf area, node at first female flowering, node at first male flowering, number of fruits per vine, average fruit weight, fruit length, fruit breadth, yield per vine, fruit cavity size, fruit flesh thickness and number of seeds per fruitare indicates the predominance of additive gene action. Hence, improvement of these traits through simple selection breeding method for improvement of wild melon would be rewarding.

Abstract: The Effect of different packaging materials on the storage life and quality of Kinnow were investigated. Fruits of Kinnow were harvested at physiological maturity and divided into requisite lots for further handling. First lot of fruit was packed in packaging films viz. LDPE film, LDPE film with 0.01% perforation, LDPE film with 0.02% perforation, HDPE film, HDPE film with 0.01% perforation, HDPE film with 0.02% perforation, PP film, PP film with 0.01% perforation, PP film with 0.01% perforation. The control fruits were kept unpacked. The fruits were stored under cold condtion (4-6°C and 90-95% RH). The observations on various physico-chemical quality attributes of fruits were recorded at different storage intervals. The data revealed that under cold conditions, Kinnow fruits were packed in PP, HDPE and LDPE film can be stored for 20, 40 and 60 daysas compared to control fruits which maintained storage life of 10 days. The use of PP, LDPE and HDPE seems to hold promise in extending the marketability of Kinnow fruits stored under cold conditions at 4-6°C.

Abstract: India is an agricultural country, and hence a lot of water is required for farming. Water should be used in a proper way. In this paper is presented the “Wireless Sensor Network based Automatic Drip Irrigation Management’’. An automation of irrigation systems has several positive effects. Once installed, the water distribution on fields or small-scale gardens is easier and does not have to be permanently controlled by an operator.In this paper we are giving brief outline of improving Throughput and Average end to end delay of information gathered from the agriculture field for Precision Agriculture. This system provide delivery of water level information signals to base station as it also computes a threshold as well as does calculates values based on transmission range. This over all computational mechanism helps us to build a robust mechanism for delivery of information to base station thus reducing the packet loss. A Wireless Sensor Network is a system consisting of radio frequency transceivers, sensors, microcontrollers and power sources. Recent advances in wireless sensor networking technology have led to the development of low cost, low power, multifunctional sensor nodes. Sensor nodes enable environment sensing together with data processing. Sensors are able to network with other sensor systems and exchange data with external users. Sensor networks are used for a variety of applications, including wireless data acquisition, environmental monitoring, irrigation management, safety management, and in many other areas.

Abstract: Biology and morphometrics on lace bug Urentius hystricellus (R.) (Tingidae: Hemiptera) in off season pigeonpea under controlled condition (26 ± 1 °C temperature, 14:10 L:D photoperiod and 60 ± 10% RH) revealed that five nymphal instarstook 13.6 ± 1.96 days to enter into adult stage (5.7 ± 0.97 days) with pre-oviposition and incubation period of 2.9 ± 0.74 and 6.3 ± 1.49 days respectively. Final metamorphosis stage of tinged bugs is very characteristic densely reticulated body surface and hemelytra. The total life cycle of lacewing bug observed 28.5±9.67 (4 to 5 weeks) days.Morphometric studies revealed that, mean length and width of eggs were measured about 0.45±0.014 mm and 0.16±0.014 mm respectively. However, among five nymphal instars, first nymphal instar of mean length and width was measured about 0.52±0.033 mm and 0.19±0.016mm respectively. Mean length and width of adult was measured about 0.35±0.075 mm and 0.86±0.016 respectively. The incidence of tinged bug pest population recorded in off season pigeonpea plants from 5th May to 5th July revealed that, there was maximum population recorded in the hotter months during May and June on an average of 29 to 44 nymphs and adults per 3 leaves at bottom, middle and top. This was positively correlated with Maximum temperature (r= +0.442). However, in July month drastic reduction of population was observed on an average of 18 nymphs and adults from bottom, middle and top leaves (3 leaves). This shows that, pest population was negatively correlated with minimum temperature (r= -0.288) and in later months the population was almost declined.

Abstract: The present study was conducted purposively in Latur district of the Marathwada region of Maharashtra state. From this district six tahsils were selected. Four villages from each taluka were selected purposively. The total villages for the study were 24. Ten respondents from each village were selected purposively for the study. Comprising 120 respondents of Deoni cattle and 120 respondents of Non-descriptive cattle from Latur district were selected. Thus, there were a total of 240 respondents selected for the research study. Ex-post facto research design was adopted in this study. The data were collected with the help of pretested interview schedule. The statistical methods and tests such as frequency, and percentage were used for the analysis of data. From the study it was found that, Deoni cattle rearers reported that lack of knowledge about management of pregnant cow and newly born calf was the most important constraint (91.67 %) in the management of pregnant cow and newly born calf followed by lack of knowledge about improved dairy production practices (90.00 %) and lack of contact between dairy farmers and veterinarians (76.00 %) was reported as secondary constraints reported by Deoni cattle rearers. Inadequate knowledge about breeding practices (94.17 %). In the context with non-descriptive cattle rearers lack of knowledge about improved dairy production practices (93.33 %) was reported as major problem followed by lack of knowledge about management of pregnant cow and newly born calf (92.50 %) and lack of contact between dairy farmers and veterinarians (76.67 %). However, they were reported that inadequate knowledge about breeding practices (97.50 %) was the major constraint in adoption of breeding management practices.

Abstract: The problem of mastitis is the most occurring and rising disease in dairy cattle world-wide. It is also responsible on milk production and composition effects by a more or less severe depression. Summary values in the literature for losses of milk production were proposed at 10 to 15% drop in early stage. The disease was more associated with high lactating females and its occurrence was more during spring and summer months. The physico-chemical properties were pointed out that specific gravity acidity, fat content and total solid decreases was significantly (p>0.05) with severity of mastitis. To support decision making for udder health control, it is necessary to use a marginal approach, based on the comparison of the losses avoided and the additional costs of modified plans, compared to the existing ones.

Abstract: A field experiment was conducted during kharif season of 2006-07 and 2007-08 to study the effect of plant growth regulators on reproductive efficiency and seed yield in pigeonpea. Two pigeonpea genotypes (Bahar and PDA-87-3E), indeterminate type and long duration were sprayed with 3 concentrations of a growth retardant, 10 days prior to flowering followed by a spray of 3 concentration of a growth promoter at 50 per cent flowering stage. There were two control treatments as no spray and water spray. Significant increase in number of flowers produced per plant, number of pods per plant, pod setting percent and 100- seed weight was observed due to growth regulator treatments. There was reduction in number of flowers shed per plant and flower drop per cent due to growth regulators. CCC (4000 ppm): NAA (40 ppm) showed the minimum number of flowers shed per plant and percent flower drop but CCC (4000 ppm): NAA (20 ppm) showed the maximum number of pods per plant. Seed yield on per plant and Kg per ha basis and harvest index showed significant increase due to growth regulator treatment with CCC (4000 ppm): NAA (20 ppm) giving the best results.

Abstract: Field experiment was carried out during the kharif season of 2012-13 to evaluate the effect of different solid and liquid forms of organic manure on growth and yield of soybean. The treatment consisted of three sources of solid (Vermicompost 2.6 t ha-1, Farmyard manure 16 t ha-1 andPoultry manure 2.2 t ha-1 ) and liquid (Panchgavyaand Fish Amino Acid) forms of organic manures and two cultivars (JS 335 and JS 95-60). The experimental results revealed that FYM + Panchgavya + Variety JS 335 recorded at all stages (growth stages plant height (55.33 cm) number of branches plant-1(12.13) and dry weight g plant-1 (12.00), there were significant difference between treatments. The maximum biological yield (6191.66 kg ha-1), net return (72925.66 Rs. ha-1) and B :C ratio (2.66) observed in treatment T10 (Farmyard manure + Panchgavya + Variety JS 335), but highest oil content (20.00%) and chlorophyll content (49.53%) observed in treatment T2 (Vermicompost + Panchgavya + Variety JS 335) and protein content(38.49%) observed in T6 (Poultry manure + Panchgavya + Variety JS 335).

Abstract:Effect of collar rot fungus, Aspergillus niger on seed germination and seedling vigour of groundnut genotypes was studied.In vitro experiment was conducted at the Department of Seed Science and Technology and in screen house of Department of Plant Pathology, CCS Haryana Agricultural University. Significant per cent reduction in plumule and radical length, fresh and dry weight including vigour index between inoculated and un-inoculated seeds with A. niger was observed. Similar reduction was also observed in per cent germination which ranged between 10.52 to 20.00 per cent in comparison to un-inoculated control. Plumule length of seedlings was significantly reduced in vitro conditions after inoculation with the pathogen, which ranged between 19.78 to 25.18 per cent. Similarly, the radical length was also significantly reduced in all genotypes within a range between 19.04 to 23.90 per cent in comparison to un-inoculated control. Fresh and dry weight of seedlings were also reduced by inoculation of seed in Petri plates by using blotter paper in vitro and the reduction in fresh weight ranged between 26.59 to 34.02 per cent, while the reduction in dry weight ranged between 26.19 to 37.93 per cent under seed inoculation technique on Petri plates in comparison to un-inoculated conditions.

Abstract: The present investigation was carried out during kharif 2014-15 at three locations viz., Regional Agricultural Research Station, Lam Farm, Agricultural Research Station, JM Puram and Agricultural College Farm, Bapatla. Seventy two inter-specific cotton hybrids were tested over three environments to identify the stable performing hybrids. The Eberhart and Russell stability model analysis was carried out to study the genotype × environment interaction for all the fibre quality traits along with lint yield plant-1. The variance due to genotypes, environments (linear) was significant for all the characters whereas, Genotypes × Env (Lin.) variance was significant for all the traits except for fibre elongation. The hybrid SCS 793 × GSB 40 had recorded higher grand mean with regression coefficient nearly one and non-significant deviation from regression (s2di) and was found to be stable for 2.5 % span length and bundle strength over three locations. Hence, this hybrid may be exploited commercially for cultivation over a wide range of environments after thorough testing over number of locations in different seasons.

Abstract: A field experiment was conducted for two consecutive years to evaluate resistance in chickpea genotypes against dry root rot and stunt virus. Total one hundred and fifty one (151) genotypes were evaluated against dry root rot in which only JG315 showed resistant reaction. Based on the pooled incidence data of two year experiment one hundred twenty nine entries including seventy four Desi and fifty five Kabuli type were found moderately resistant while fifteen genotypes consisted of eight Desi and seven Kabuli type under tolerant category. Moreover six Desi type viz., GJG1001, GNG2171, DC2012-4, IPC2007-13, CSJ647, RSG931 and one Kabuli type genotype (JGK18) were found under susceptible category. A separate evaluation trial was conducted for stunt disease and response of total one hundred fifty (158) genotypes has assessed for disease reaction. Among evaluated entries only GCP105 showed resistant reaction while fifty eight entries including thirty three Desi and twenty five Kabuli type were found under the category of moderately resistant. Total eighty five entries included fifty five Desi and thirty Kabuli type, eleven entries consisted of six Desi and five Kabuli type, three entries having one Desi and two Kabuli type were depicted as tolerant, susceptible and highly susceptible respectively. Based on findings of both experiments eight Desi type viz., CSJ513, G10023, JG38, GNG469, IPC2009-191, H10-41, JG40, H10-57 and five Kabuli type viz., NBeG176, HK10-124, CSJK74, IPCK2006-143, IPCK2009-164 were found promising against both devastating diseases of chickpea. The information generated under both experiments can be exploited in breeding programme for the development of new variety having resistance against these diseases.
