Abstract: The maceration techniques viz., cold soaking and thermovinification were employed to enhance the color stability of jamun wine. These maceration methods were tried on the three must types such as juice, pulp+skin and pulp+skin+seed. The physico-chemical and sensory qualities of the wine were recorded in fresh, three and six months old wine. The results indicated that, TSS and pH of the wine were maximum (11°B & 3.74 %, respectively) in the fresh wine. The results were statistically on par with the treatment involving thermovinification with pulp+skin+seed (T9). Phenolic content was maximum (384.74mg/l) in treatment involving cold soak with pulp+skin+seed while, the minimum (223.33mg/l) was recorded in the treatment involving thermovinifiedmust containing juice in the freshly prepared wine. Alcohol content was maximum (9.44%) in the treatment without any maceration in the must containing juice+skin+seed in the fresh wine. Overall acceptability sensory scores (17.40 out of 20) of the jamun wine was maximum in the thermovinified must containing pulp+skin (T8). In conclusion, maceration methods especially thermovinification helps in increasing the acceptability, colour stability and overall quality of the jamun wine. Jamun fruit can be a potential candidate for processing into a healthy wine with good antioxidant activity.

Abstract: Generated and determination of genetic diversity is useful for plant breeding loading production of more efficient plant species under different conditions. Accordingly, Indian mustard (Brassica juncea L.Czern and Coss.) genotypes including 19 diverse parents with their 60 F’1s and one check variety under Timely sown condition was analyzed for genetic diversity and heritability. The maximum range was observed for days to maturity followed by plant height, biological yield, days to 50% flowering and oil content. The high narrow sense heritability was observed for days to 50% flowering, 1000 seeds weight, and plant height. The divergence analysis based on Tocher’s analysis indicated the presence of appreciable amount of genetic diversity in the experimental materials. The eighty mustard genotypes were grouped into nine clusters and cluster II was largest while Cluster VI, VII, VIII, and IX were having only one genotype. The maximum inter-cluster distance was observed among cluster VI and cluster IX. The principal components analysis revealed that five principal components (PC1 to PC5) accounted nearly 81.93% of the total variation.

Abstract: Black gram is grown mainly during kharif season. However, its cultivation in rabi season is restricted to the eastern and southern parts of the country, The nutrition of a plant determines its resistance or susceptibility to diseases, its histological or morphological structure, the function of tissues to hasten or slow pathogens and the virulence and ability of pathogens to survive. Many of the potential interactions of minerals in defence mechanisms can be postulated from their intimate and extensive functions in plants. in the present investigation, MnSO4 (0.3%) reduced the disease incidence more effectively cercospora leaf spot. Similar trend was observed in powdery mildew the application of MnSO4 (0.3%) is followed by MgSO4 (0.5%) and MnSO4 (0.3%) + CuSO4 (0.2%) both of them as compared to control, indicating that these nutrients offer greater resistance for the invasion of cercospora leaf spot and powdery mildew pathogens.

Abstract: The present investigation was carried out to study association among the different biometrical and harvest plus traits with grain yield in pearl millet. The experimental material comprised of 100 advance inbred lines grown in randomized block design with three replications under rain fed conditions.The observations were recorded for 12 quantitative traits [Days to 50 per cent flowering, plant height (cm), spike length (cm), spike girth (cm), total number of tillers (number/plant), effective number of tillers (number/plant), leaf length (cm), leaf width (cm), ear weight (g), grain yield (g/plant), dry fodder yield (g/plot), 1000-grain weight (g)] and two harvest plus traits [ Iron and Zn content (mg / kg grains)]. Correlation analyses were carried out to find the association at phenotypic and genotypic levels among different characters. Grain yield/plant expressed positive and significant correlation with dry fodder yield (0.84) followed by ear weight (0.79), total tillers/plant (0.19), effective tillers/plant (0.19), spike girth (0.16) and plant height (0.15). There was significant and positive association between many traits indicating that these traits could be improved simultaneously. The path coefficient analysis revealed that highest positive and direct effects on grain yield per plant was exerted by dry fodder yield (0.60) followed by total tillers per plant (0.44), ear weight (0.43), and effective tillers per plant (0.38). On the other hand, days to 50 per cent flowering (-0.12), and leaf width (-0.01) had negative direct effects on grain yield per plant. Therefore, selection for higher yield will be useful if it is based on traits such as dry fodder yield, ear weight, total tillers/ plant and effective tillers/plant.

Abstract: The present investigation was conducted to ascertain the effect of pruning (10-20cm of shoot length) and bio regulators (NAA 250ppm, Urea 15%, Ethrel 500ppm and Cycocel 50ppm) on vegetative growth parameters of guava variety Sardar. Observations revealed that pruning treatment significantly influenced the vegetative growth parameters of trees. Significantly minimum plant height (3.26m), stem girth (15.60cm) and plant spread (NS 7.06 and EW 7.19m) were noted in pruned plants. Although, plant growth in terms of height, stem girth and overall plant spread restricted under all bio regulator treatments, effect of cycocel was more pronounced. Reduction in the plant height (3.64m) at 120 DAT was recorded in ethrel treated plants, whereas cycocel treated plants exhibited maximum reduction in stem girth (16.51cm) and E-W canopy spread (7.24m) 120 DAT. Minimum plant spread (7.22m) in N-S direction was recorded in NAA treated plants.

Abstract: The results of pool data of two year revealed that among the organic treatments, O4 showed superiority with respect to growth and yield parameters over O1 and O2 but it was closely followed by O3. The values recorded with O4 treatment of plant height at harvest (123.06 cm), stem girth at harvest (35.64 cm), petiole length (46.33 cm), number of leaves/plant (33), number of fruits/plant (22.33), average fruit weight (0.956 kg), fruit yield/plant (21.68 kg) and fruit yield (68.83 t/ha) were significantly higher as compared to rest of the organic treatments. However, application of sap @ 8 l/plant in 8 equal splits (S1) increased the plant height, girth, number of fruits/plant and fruit yield (t/ha) by 12.3, 17.0, 6.8 and 11.2 per cent, respectively over no application of sap (S0).Similarly, the yield attributes viz., average fruit weight, number of fruits per plant and fruit yield (t/ha) were also differed significantly between the mean of organics treatments and INM control. Under both the farming system, the economics was computed in two way i.e. selling price same for organic as well as INM fruit and premium price for fruits of organic nutrient management system. At same price of fruit (Rs 5/kg), the net profit realized with INM was Rs. 3, 07,520/ha with BCR of 3.3 as against the net profit of Rs. 1,32,224/ha with BCR of 0.77 with organic treatment mean. The best organic treatment O4 the net profit (1, 61, 788 Rs/ha) was almost half of the INM. Alternative scenario generated by considering premium price for organic product (Rs 10/kg), the net income realized was raised to Rs. 4,36,674/ha with BC of 2.53. This was also true for S0 and S1, where S1 recorded net profit of Rs. 4,47,914/ha with premium price as against Rs. 4, 08,506/ha with S0.

Abstract: Manjari gota fruit type of brinjal is most popular in south India due its colour, taste and flesh. Manjari gota fruittype refers to brinjal fruits with purple colour with white stripes. The study was carried out to estimate the magnitude of heterosis over better parent and commercial checks for some important characters in 21 crosses resulting from Line x Tester mating design of 7 inbreds as lines and 3 inbreds as testers in Manjari gota type of brinjal. Among the 21 crosses, IIHR-575 x IIHR-500 A was highly heterotic for fruit length (32.70%), number of fruits per plant (39.33%), plant height (23.50%) and yield per plant (69.56%) over commercial check and could be exploited for commercial cultivation. The cross IIHR-574xIIHR-571 exhibited significant heterosis over commercial check (-3.71%) for days for fifty percent flowering and (-14.27 %) days to first fruit harvest. The cross IIHR-575 x IIHR-438-2 showed highest magnitude of heterosis (10.10%) over commercial check for percent fruit set. The cross IIHR-575 x IIHR-571 recorded highest magnitude of heterosis (14.22%) over commercial check for average fruit weight. The number of primary branches were significantly more in cross IIHR-592 x IIHR-438-2 (52.07%) over commercial check.

Abstract: The genetic correlation and path coefficient analysis were studies in thirty three germplasm in chilli for twelve quantitative and four qualitative characters. Correlation provides information on the nature and extent of relationship among the characters. The genotypic correlation coefficients were higher than phenotypic correlation coefficients for all the characters. The genotypic correlation coefficient revealed that yield per plant displayed significant and positive association with ascorbic acid content (0.438), plant height (0.404), capsanthin content (0.398), mean pod weight (0.348), pod length (0.346), and capsaicin content (0.226) and negative association with number of pods per plant (-0.096), number of seeds per pod (-0.085), pod girth (-0.066), carotene content (-0.001). Path coefficient analysis provides an aid for sorting out the total correlations into direct and indirect effects of different characters on yield. To get an insight into these relationships, the path coefficients were worked out for sixteen yield contributing characters. The path coefficient analysis revealed that mean pod weight, number of secondary branches per plant and plant height, red pod yield per plant, capsanthin content, carotene content and capsaicin content could be considered major yield components and give importance while exercising selection.

Abstract: The present investigation was conducted to study genetic variability, heritability, genetic advance and correlation coefficient analysis in chickpea. On the basis of mean performance, high grain yield per plant was exhibited by the genotype C-210 (10.03g) followed by C-206 (8.34g), C-226 (7.51g) and C-207 (7.13g). Analysis of variance revealed high significant difference among 13 chickpea genotypes for all characters, indicating the existence of high variability. High Genotypic Coefficient of Variation (GCV) and Phenotypic Coefficient Variation (PCV) was observed for seed yield per plant (22.16, 29.87), biological yield (19.39, 24.82) and harvest index (17.64, 25.69). High estimates of heritability were observed for number of pods per plant (71.2) and biological yield (61). High genetic advance were observed for number of pods per plant (9.97), harvest index (8.56) and biological yield (5.94). Genetic advance as percent of mean was observed for seed yield per plant (21.39), biological yield (31.2), harvest index (24.97), number of pods per plant (24.23), number of branches per plant (22.31) and seed index (21.39). High heritability coupled with high genetic advance as % mean observed for number of pods per plant (71.2, 24.23) and biological yield (61, 31.20). Grain yield per plant at genotypic and phenotypic level was positively significant correlated with number of branches per plant (0.72**, 0.44**), biological yield (0.65**, 0.56**) and harvest index (0.28**, 0.52**).

Abstract: Heterosis plays an important role in achieving improvement in crop production. About 69 F1 hybrids obtained by crossing twenty three lines and three testers in a line × tester fashion were used to derive the information on degree of heterosis over mid, better and standard parent in maize. Sixty nine crosses and their parents including one check CoH(M)5 were evaluated in a Randomized Block Design with two replications. Grain yield per plant recorded the standard heterosis ranged from -47.04 (N10-68­ x UMI 285-5) to 51.02% (N09-157 x N171-2) and significant positive standard heterosis recorded by fifty two hybrids over the check. For grain yield per plant, high heterosis was observed in four hybrids viz., N09-157 X N171-2 (51.02%), N09-150 X N148-1 (48.71%), N10-105 X N148-1 (48.06%) and N09-153 X UMI 285-5 (42.51%). These hybrids also showed high heterosis for many yield contributing traits in desirable directions. Therefore these hybrids can be utilized in future for developing high yielding hybrid varieties as well as for exploiting hybrid vigor.

Abstract: Indian arid zone is one of the largest subtropical deserts of the world of which 20% is arid and rest is semi-arid with varied habitats. The hot arid region occupies major part of north-western India including Rajasthan, Gujarat, Punjab and Haryana (73% of total arid region). In fruit crops, one of the major constraints for productivity aretemperature and frost.These both are severely affects the plant growth, yield and quality of arid regions fruits because it reduces the pollination, while increase fruit drop and cracking of the fruits.These effects are either due to direct injuries or due the reduced activity of enzymes and disturbed metabolic processes in ber, anola, pomegranate and kinnow. In addition, with improved understanding, options for better management plans including irrigation management (drip irrigation and other practices), pruning and canopy management, replanting, mulching, growth regulators and anti- transpirant become important for sustaining fruit yields. The present review made for the better understanding of the effects of abiotic stress to morphological, physiological changes on fruit crops and itsmanagement in arid regions of India.

Abstract: The present investigation was carried out during 2012-13 with twelve Pea (Pisum sativum L.) cultivars for protein profiling of seed protein through SDS-PAGE. The profiles of pea cultivars were studied by extracting the total seed proteins from 12 cultivars and performed SDS-Polyacrylamide gel electrophoresis. On the basis of banding patterns through SDS-PAGE, indicated that the number of bands found in cultivars ranged from 12 to 19 with Rm value 0.12 to 0.9. Among all the cultivars, the cultivar KPMR-400 had recorded highest number of bands (19) whereas, the minimum number of bands (12) observed in three cultivars viz., KPMR-921, KPMR-902 and KPMR-913. The total seed protein variation were also analyzed using Un-weighted Pair Group Method with Arithmetic Mean (UPGMA) and resultant cluster analysis based on the data of protein profiling, classified twelve cultivars into six major groups. Finally the study concluded that, the protein variability analysis clearly showed that there was sufficient genetic divergence among these cultivars of pea with respect to seed storage protein. Among all the cultivars, the KPMR-906 in cluster IV having wider genetic diversity and suggested to utilize in future crop improvement program.

Abstract: The growth retardants are used for controlling growth and flowering of chrysanthemum. A study was undertaken to investigate the concentration and frequency of application of growth retardants as foliar spray to regulate the growth, flowering and flower quality of spray cut chrysanthemum var. Punch. The study was conducted at a private farm, M/s. Salem Green Plants Ltd., Yercaud, Salem as a greenhouse experiment in randomized block design with 19 treatments and three replications. The treatment comprises of two growth retardants viz., Daminozide at four different concentrations (1000 ppm, 1500 ppm, 2000 ppm & 2500 ppm) with three frequencies (7, 14 & 21 days after darkening) and Maleic Hydrazide at three different concentrations (500 ppm, 750 ppm & 1000 ppm) with two frequencies (7 & 21 days after darkening) along with control (No spray).Growth and flowering parameters viz., plant height, chlorophyll contents, days to first flower bud appearance and flowering, pedicel length, cut stem girth, number of flowers per spray, stem fresh weight and dry matter content were measured. Significant differences (p<0.05) were observed for all the parameters studied across growth retardant levels. Daminozide showed a longer inhibitory action than maleic hydrazide for plant height. Daminozide 2500 ppm with single spray at 7 days after darkening improved days to first flower bud appearance (44.72 days) and flowering (81.83 days), pedicel length (5.87 cm), cut stem girth (3.24 cm), stem fresh weight (68.00 g/stem), number of flowers per spray (14.87) and dry matter content (40.31 per cent). Hence, based on the results obtained, a single application of daminozide concentration of 2500 ppm at 7 days after darkening may be recommended to improve growth and flower quality of ‘Punch’ chrysanthemum under greenhouse conditions.

Abstract: Millet is a generic term describing a range of small-seeded grains in two tribes Paniceae and Chlorideae of the family Poaceae (true grass). It became a staple food for humans 10,000 years ago already before the rise of wheat and rice. The cultivation of millets is highly recommended for drought prone regions because these are low water consuming crops. Most of millets are grown in low fertile soils. Finger millet is the third most important millet in India (locally called as Ragi), next to sorghum and pearl millet,coveringanareaof2millionhectareswithannualproductionof2.15milliontonnes.InKarnataka,itis grown in an area of 0.8 m ha with an annual production of 1.34 mt. Currently the key millet growing regions in the state are Pauri Garhwal, Tehri Garhwal, Uttarkashi, Chamoli, Rudrpryag, Pithoragarh, Champawat, Bageshwar, Almora and Nainital district. Finger millet (Eleusine coracana (L.) Gaertn) is the primary food source for millions of people in tropical dry land regions. It also has nutritional qualities superior to that of rice and is on par with wheat. Finger millet is used in various food preparations. It is usually converted into flour and made into cakes, bread and other bakery products. The sprouted seeds are also nutritious and easily digested. The grain may also be malted and a flour of the malted grain is used as a nourishing food for infants.

Abstract: A field experiment was conducted to study the effect of poor quality water irrigation in conjunction with different management practices on sorghum leaf area index (LAI) and quality of grain. The results of the experiment indicated that there was a significant influence of poor quality water irrigation and management practices on performance of sorghum. The highest LAI was recorded with C2 (good) quality water which was on par with C3 (marginal) quality. Alternating the irrigation with C3/C4 quality water was found to be better than C4 (poor) quality. Application of FYM @ 10 t ha-1 has recorded the highest LAI of 1.78, 6.03 and 4.28 at 30, 60 and 90 DAS respectively followed by in situ green manuring which was significantly higher over magnetic treatment. Among water quality levels, the highest protein content was recorded by C2 (9.62%) followed by C3 (9.00%) and C3/C4 (8.68%). Among management practices, the highest protein content was recorded by FYM (10.96 %) followed by green manure treatment (9.60%). The highest starch content was noticed in C2-FYM (67.12%) followed by C3-FYM (66.78%) and C3/C4-FYM (66.66%).

Abstract: The extreme lowest temperature (ºC) recorded over the periodduring 1986 -2015in different years showed the decreasing trend and after 2000, the extreme of lowest temperature further decreasedat fasterrate below the normal withgreater magnitude in subsequent years.Fortnightly variation of frost during November to February (1986-2014) were studied and found that December second and January first fortnight possess maximum frost occurance frequency on event and percent arability basis. The decadal variation of frost occurrence on monthly basis has also been studied on long term data (1986-2015) and found that number of frost events increased from 29 to 57 from first decade (1986-1996) to recent decade (2006-2015) i.e. almost doubled. January was reported the month having highest occurrence frequency of frost in all decades. On per cent probability basis also January was reported the highest % of probability (90%) of frost occurance in all decades. November & Feb were frost free months in all decade in the area. The increasing tendency of frost occurance in recent years in the area will force to make contingent plan and adoptive measures from frost protection. In view of the study Rabi crop planning and management is necessarily required including contingency planning and risk management strategy to combat the crop losses due to extreme low temperature or frost.
