Abstract: The present study was conducted to evaluate the effect of growing media, hormonal treatments and growing seasons on the shoot and root characters and survival percentage of cuttings of lemon cv. Pant Lemon-1.Pooled data of two season (rainy and spring) has shown that soil+sand+FYM growing medium resulted maximum length of sprouts and average number of leaves per cutting. Whereas, average diameter of shoot and average length of longest roots were maximum in soil+cocopeat based medium. Average diameter of root was higher in soil+cocopeat and soil+FYM medium, but did not differ significantly. Maximum survival percentage of cuttings was noted with soil+sand+FYM. IBA (500 ppm) was found superior regarding for all parameters except on average diameter or roots per cutting with IBA+NAA (500 ppm each). Taken as a whole, rainy season was found superior over spring season in respect to all shoot and root characteristics.

Abstract: Coriander (Coriandrum sativum L.) is an annual spice herb that belongs to the family Umbelliferae. Even though Ethiopia is a centre of primary diversity for the crop, the current knowledge about its biology, variety development and agronomy is neither complete nor conclusive under ethiopian conditions. To contribute to filling some of the existing gaps, a field experiment was conducted during the year of 2011-12 a seventy one accessions of coriander were screened for resistance against stem gall, a sever disease caused by Protomyces macrosporus Unger., with the goal to select the resistant cultivars. The accessions DCC-37 (Devihosuru coriander collection), DCC-49 and DCC-51, DCC-10, DCC-32 and Sudha were highly resistant. These may be used as the parents to breed high yielding accessions resistant to stem gall disease.

Abstract: This study an attempt was made to assess the organoleptic acceptability and nutritive value of value added food products prepared from the incorporation of less utilized dehydrated lahsua leaves which are usually discarded or are used as animal fodder. The lahsua(Digera arvensis) leaves powder was done through tray drying at 60- 650C for 15 hours. The products prepared were biscuit and namakpare by incorporation of dehydrated lahsua leaves powder at 15, 20, 25% and served as treatments T1, T2 and T3 respectively. T0 without incorporation of dehydrated lahsua leaves powder served as control. Organoleptic evaluation was carried out using the nine point hedonic scale and nutritional composition was calculated using the food composition table given by ICMR. On the basis of findings, it was observed that namakpare and biscuit T1 (15 percent) was found to be best with regards to flavour and taste and overall acceptability. It was also observed that calcium, iron, protein and total carotene content in prepared products increased significantly as the incorporation levels increased. Thus dehydrated Lahsua leaves powder can be incorporated in the preparation of different food products to improve their nutrient contents.

Abstract: Genetic variability and heritabilitystudies involving eight genotypes of gaillardia (Gaillardia pulchella Foug.) indicated that there were highly significant differences between the genotypes for most of characters studied. The analysis of variance revealed that highly significant differences among genotypes for all the characters studied. The phenotypic coefficients of variations (PCV) were higher than genotypic coefficient of variation (GCV) for all the characters studied. However higher PCV and GCV estimates were found for number of branches per plant, number of leaves per plant, flower yield per hectare and seed yield per plant. Estimates of high heritability with high genetic advance over per cent mean for growth characters were observed for plant height, number of branches per plant, number of leaves per plant, leaf area and chlorophyll content. And for flowering traits, it was recorded in duration of flowering, days taken for seed setting, indicating the possible role of additive gene action.

Abstract: Radish (Raphanus sativus) is one of the major vegetable crop grown throughout the country. It is widely grown in different parts of the country mainly by small and marginal farmers. The planting operation of the radish crop is not mechanized in India, with most of the area cultivated by line sowing and broadcasting operation. However, problem of flow of material are experienced. Pelletizing of the radish seed by providing a seed coat, helps in changing the physical characteristics of the seed. The biometric properties of seeds play an important role in designing seed metering device. Physical and engineering properties of radish seed both un-pelleted and pelleted (T0, T1, T2 and T3) were evaluated in the laboratory. The average major and intermittent dimension of T0, T1, T2 and T3 seed were 3.31 mm, 3.75 mm, 4.27 mm, 4.35 mm and 2.72 mm, 3.11 mm, 3.64 mm, 3.84 mm, respectively.T3 enhanced the major and intermittent dimension of seeds. Roundness value and sphericity of T0, T1, T2 and T3 seed were 0.70, 0.79. 0.82, 0.90 and 0.78, 0.84, 0.85, 0.91 respectively. The geometric mean diameter was maximum for T3 radish seed (3.94 mm) followed by T2 (3.65 mm), T1 (3.14 mm) and T0 (2.58 mm) radish seed. Thousand seed weight, W 1,000 of T0, T1, T2 and T3 was 11.74 g, 23.43 g, 32.86 g and 46.05 g respectively. Angle of repose and static coefficient of friction for mild steel surface were 28.81o, 25.09o, 23.70o, 23.16o and 0.54, 0.65, 0.69, 0.82 for T0, T1, T2 and T3 radish seed respectively. The values of porosity are decreased in gradually T0, T1, T2 and T3 seeds whereas the porosity for T3 seed was 44.51% and is the lowest amongst the other treatments. The porosity of T0 seed was the highest (47.78%).

Abstract: For utilizing the full potential of wheat variety PBW 502, two consecutive experiments were carried out at Crop Research Station, Masodha of N. D. University of Agriculture and Technology, Faizabad (U.P.) during rabi season of 2012 and 2013 to study the effect of sowing methods, NPK levels and zinc sulphate on grain yield and its attributing traits in wheat (Triticum aestivum L.). The experimental field was laid out in Split Plot Design with three replications keeping two methods of sowing viz. S1 (Ridge method) and S2 (Flat method) in the main plot and three fertilizer doses viz. F1 (Recommended dose of fertilizers), F2 (RDF + 25% higher dose) and F3 (RDF + 50% higher dose) in sub plot. The four levels of zinc sulphate (@ 10, 20, 30 and 40 kg ha-1) were also applied in the sub plots. Periodical observations were recorded on growth, yield attributing characters and grain yield. The results revealed that various methods of sowing had significant effect on plant height at all the stage of crop growth (except at dough stage), days to 50% heading, yield attributing traits and grain yield. The varied doses of fertilizers had significant response on all the stages of crop growth as well as days to 50% heading. Increasing levels of NPK and zinc sulphate significantly influenced most of the yield components. Maximum yield potential can be obtained under ridge method of sowing along with the application of RDF + 25% higher dose and zinc sulphate @ 30 kg ha-1 which also improved the yield attributing traits like number of productive tillers/plant, spike length (cm), number of spikelets/spike, number of grains/spike, test weight (g) and seed recovery (%).

Abstract: The present study was conducted on seventeen diverse genotypes of cotton belonging to different parts of India to analyze the parameters of genetic variability for seed cotton yield and its components at Cotton Research Area, Punjab Agricultural University, Ludhiana and Regional Station, Faridkot, Punjab. Analysis of variance revealed significant differences for all the traits at both locations indicating sufficient variability present in the material. The phenotypic coefficient of variation (PCV) ranged from 7.95 to 34.66 at Faridkot whereas at Ludhiana it varied from 6.47 to 26.45 for ginning out turn and lint yield, respectively. Heritability ranged from 24.18 to 94.91 at Faridkot and 45.71 to 91.38 at Ludhiana, for boll weight and lint yield respectively. High genetic advance (GA) was observed in only two traits seed cotton yield (31.41 & 26.87) and plant height (28.12 & 19.19). High heritability coupled with high genetic advance as percentage of mean (GAM) was recorded for seed cotton yield (59.86 & 41.39), boll number (25.62 & 33.93), lint yield (57.71 & 49.79) and number of sympods (51.75 & 41.15) at Faridkot and Ludhiana respectively. Hence simple selection based on phenotypic performance of these characters would be more effective.

Abstract: A long term field experiment on the transformations of phosphorus under different nutrient management practices and cropping systems in Vertisol (Typic Haplustert) of Northern Transition Zone of Karnataka was initiated in 2004-05 at the Institute of Organic Farming, Main Agricultural Research Station Farm, UAS, Dharwad. Application of organic manure continuously for eight years decreased all the fractions of phosphorus. Hundred percent inorganic nutrient management practice recorded statistically higher phosphorus fractions in the order Ca-P (45.5 mg/kg) > Al-P (35.9 mg/kg) > Fe-P (22.3 mg/kg) > occluded-P (14.6 mg/kg) > saloid-P (11.4 mg/kg) at both the depths (0-30 cm and 30-60 cm) while available-P (23.8 kg/ha) was statistically lower in this system when compared to other nutrient management practices. All the fractions of phosphorus (saloid-P, Al-P, Fe-P, Occluded-P and Ca-P) were highly inter-related and significantly correlated with each other and negatively correlated with available phosphorus content.

Abstract: Experiments were conducted to develop and evaluate the quality of jaggery based papaya leather .The citric acid levels of 0.5%, 0.75% and 1.0% were used for the preparation of papaya leather. After preparation of papaya leather, the finished products were packed in PET and glass jars. The study revealed that the moisture content increased while TSS and Vitamin-C decreased with increasing the level of citric acid from 0.5 to 1.0%. During storage there was a reduction in moisture content, pH and vitamin-C, where as TSS (total soluble solids) and optical density increased during storage. The organoleptic score of the leather samples in glass jars at 0.75% citric acid level was found to be higher followed by samples packed in PET jars.

Key words: acidity, leather, pH, papaya, processing, packaging material, TSS

Abstract: The present investigation was undertaken in Sorghum (Sorghum bicolor (L.) Moench) at Sorghum Research Station, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (Maharashtra) during kharif2008-09.Eight hybrids along with six parents and four checks (PVK 400, PVK 801, GMRP 9, and CSH 16) were evaluated in randomized block design with three replications. In general, higher heterotic effects were observed in the crosses involving PMS 28A and 6938B as the female parent and KR 192 and C 43 as the male parents. A total of 7, 8, 3, 8 and 7 hybrids exhibited positive and significant heterosis for grain yield over better parent and standard check viz., PVK 400, PVK 801, GMRP 9 and CSH 16, respectively. High and significant heterosis was observed in the crosses 6938A x C 43, MS 28A x C43 and PMS 28A x KR 192 for grain yield as well as earhead length, earhead girth, earhead weight, test weight, grain hardness and germination percentage. The crosses PMS 28A x C 43 and PMS 28A x KR 192 showed significantly desirable heterosis for all the four grain mold attributes viz., field grade score, grain hardness and germination percentage

Abstract: The present investigation was carried outduring the year 2006-07 and 2007-08 with main objective to find out the morpho-physiological differences between “4 regular bearing and 5 biennial bearing varieties. The experiment was layout in Randomized Block Design with three replication. The experimental material consist of 9 cultivars of mango viz., Mallika, Amrapali, Totapuri, Neelum, Dashehari, Chausa, Bombay Green and Safeda. The maximum extended shoots were observed in regular bearing variety during ‘on’ year while it was observed maximum during ‘off’ year in biennial bearing variety and during ‘off’ year in regular bearing variety. Length and diameter of extended and unextended shoots were observed maximum in biennial bearing variety during both on and ‘off’ years. Thus, it can be said, that alternate bearing problems of mango varieties can be minimize by applying the morphological and Phenological measures viz. debloosming cultural practices.

Key Words: Mango, Regular bearing, Biennial bearing, Debloosming cultural practices
