The current study was conducted at Agronomy Section,Agriculture Research Institute, Tandojam during the growing season of 2019-20,toassess new oat genotypes for their growth performance under the environmental conditions of Tandojam. For this study, a total of eleven new oat genotypes along with one check genotypewere grown for their evaluation. A total of seven characters consistingcrop stand (m-2), plant height (cm), leaves plant-1, number of tillers plant-1, leaf area (cm-2), green fodderand dry mater yield (t ha-1)were investigated. The mean squares values for the investigated traits of all the genotypes were found significantly different(P≤0.05) among the genotypes, which showsthat these genotypes possess valuable genetic combinations for further improvements. Under the agro-climatic conditions of Tandojam, the maximum crop stand (96.66 m-2), greater green fodder (86.00 t ha-1) and alsomaximum dry matter yield (43.00 t ha-1) was produced by Entry-D; the Entry-H produced the tallest plants (96.66 cm) and maximum number of leaves plant-1(68.00). WhereasEntry-F produced maximum number of tillers plant-1 (17.66). Hence, these oat genotypes may be preferred for commercial cultivation in the tested climatic conditions. Regarding correlation results, the traits crop stand (r=0.93**), tillers plant-1 (r=0.39*) and leaf area (r=0.38*) showed significant and positive associations with green fodder yield, hence these characters may be given priority in high yielding oat cultivar development

Tuberose (Polianthes tuberosa L.) is one of the most important tropical bulbous-ornamental cultivated for production of long-lasting flowers spikes. Adaptation and acclimatization of different cultivars under humid agro-climatic conditions of Goa are to be confirmed for their better performance. The present investigation was conducted to evaluate the performance of tuberose cultivars under agro-climatic conditions of Goa during 2014- 2017. Five single and six double cultivars of tuberose were evaluated during the study period. All the cultivars differed in their growth and flowering behaviour. Among the single cultivars, evaluated, maximum number of florets per spike (47.00) was observed in Pune local whereas spike-length (75.59 cm) was maximum in Mexican Single. Among the double cultivars, evaluated, maximum plant height (52.21 cm) and maximum number of leaves per plant (59.63) were recorded with cultivar Arka Suvasini. Leaf length was significantly higher (52.93 cm) in Pearl double whereas leaf width (2.04 cm) was maximum in Calcutta Double. Days to appearance of flower spike were earlier in Arka Suvasini. Minimum days taken for opening of basal floret (84.88 days) were recorded with cultivar Arka Suvasini. Spike girth (0.68 cm), Spike fresh-weight (69.06 cm), floret stalk-length (3.6 cm), floret diameter (5.24 cm), weight of individual floret (3.49 g) and vase life (7.93 days) was significantly maximum in Cv.

The deficiency of nitrogen (N) in soil restricts agricultural productivity and its overdosage pollutes the atmosphere. Nitrogen is a vital component of protein, chlorophyll and various physiological processes. When it is applied at a recommended dose, it may be lost through fixation, leaching, volatilization and denitrification, etc. Therefore, there is a dire need to harmonize the supply of nitrogen according to crop and soil requirements. Under this situation, precision nitrogen management is one of the best options. GreenSeekerTM is an integrated optical sensor with a variable application rate and mapping system that measures crops’ nitrogen requirements. To ascertain the abovementioned facts, a research study was conducted at the National Agriculture Research Center, Islamabad, Pakistan, to examine the response of fodder oat to nitrogen management (N0 = control, N1 = 80 kg ha−1 basal dose, N2 = 40 + 40 kg ha−1 split doses, N3 = 40 kg ha−1 with one-time management with GreenSeekerTM and N4 = 20 kg ha−1 with two-time management with GreenSeekerTM) and seed rate (S1 = 80, S2 = 100, S3 = 120 and S4 = 140 kg ha−1). Data were recorded on the agronomic and physiological aspects of the crop and economic analysis was performed for GreenSeekerTM-based N application against the conventional recommended dose of nitrogen application. Mean values showed that greater number of tillers plant−1 (6), fresh weight (16572 kg) and photosynthetic rate (11.64 mmol m−2 s−1) were noted in the treatment N4 (20 kg ha−1 and two-time management with GreenSeekerTM). Greater plant height (70.8 cm) and leaf area (64.14 cm2) were recorded in treatment N2 (40 + 40 kg ha−1 split doses) as compared to the control. The effects of nitrogen on fodder oat were forecasted through NDVI. The results suggested that nitrogen treatment N4 (18 kg ha−1) managed by GreenSeeker in the PARC Oat cultivar produced the maximum NDVI value (0.68) at the booting stage among all treatments. The correlation of NDVI at the tillering and booting stages with green fodder yield was positive (R2 = 0.80). Therefore, the tillering and booting stages can be good depictive stages at early and later growth stages of fodder oat under the agro-climatic conditions of Islamabad, Pakistan. Based on the results, it is recommended to apply an initial dose of 20 kg ha−1 nitrogen along with two-time management with GreenSeekerTM for obtaining more green fodder yield in fodder oat. In Crux, with N1, a total of 80 kg ha−1 nitrogen was applied to achieve an estimated net profitability of USD 582.13. With N4, a total 58 kg ha−1 nitrogen was used to achieve a net profitability of USD 836.16; therefore, this treatment was found to be environmentally safe as compared to N1 (80 kg ha−1).

Pitombeira is a native fruit tree from Amazon and is exploited in an extractive way. Currently, there is no commercial cultivation of this crop since there are no technologies for cultivation, propagation methods, fertilization and irrigation. In this context, the aim of this study was to evaluate growth and dry matter of pitombeira seedlings (Talisia esculenta (A. St.-Hill.) Radlk.) under salinity levels with or without bovine biofertilizer. The experiment was performed in a nursery at the State University of Paraíba (UEPB), Campus IV, in Catolé do Rocha, Paraíba, from September to December 2015. It was adopted a completely randomized design (CRD) with 10 treatments and 4 repetitions, in factorial arrangement 5 x 2, corresponding to 5 salinity levels: (0,8; 2; 4; 6 e 8 dS m-1) with or without bovine biofertilization. Plant height, stem diameter, number of leaves, leaf area, total leaf area, Dickson quality index, dry mass of root, stem, leaf and the whole plant were analyzed. The increase in salinity provides a decrease in growth and dry matter of pitombeira seedlings. The use of biofertilizers mitigates the harmful effects of salinity on pitombeira seedlings.

Background: Fig belongs to tropical and subtropical climates, and Haripur district being a subtropical area have great potential for successful commercial cultivation of figs. The most common method of fig propagation is by hardwood cutting, which is an easy and economical way of propagation. But lack of knowledge regarding suitable date of cutting collection and sowing and selection of appropriate potting medium severely limits the production of fig on a commercial scale. Objectives: Current study was undertaken in order to identify suitable collecting dates of fig cuttings and to develop a suitable potting media for the successful establishment of fig cutting. Methodology: The study was comprised of four different potting media i.e. Soil, Farmyard or Manure (FYM), Compost, Soil+FYM+Compost (1:1:1) and cuttings of fig cultivar Sawari were collected and sown on two different dates i.e. 1st January and 15th January in polyethene bags of uniform size. The experiment was laid in Complete Randomized Design (CRD). Results: Results revealed that maximum Length of the root (9.8 cm), Shoot thickness (1.4 cm) and Number of leaves (4.1) were noted in FYM, whereas maximum days to Sprouting (18.5) and Survival percentage (82.3%) were noted in Soil+FYM+Compost (1:1:1). Whereas fig cutting sown on 15th January showed maximum Days to sprouting (18.8), Length of the root (9.4 cm), Survival percentage (87.1%), Shoot thickness (1.8cm) and Number of leaves (4.6). Conclusion: It can be concluded that FYM and 15th January showed highest values of studied parameters.

Thirty genotypes of forage sorghum were studied for generating information on nature and magnitude of genetic variability and diversity for designing breeding programme. The experiment was conducted in randomized complete block design in three replications. The data were recorded on days to 50% flowering, plant height, leaf breadth, leaf length, leaf area, stem girth, leaves per plant, leaf stem ratio, total soluble solids, protein content and green fodder yield. Analysis of variance revealed a substantial amount of variability among the genotypes for all the characters under study, indicated a wide spectrum of variability among the genotypes. Highest estimates of the phenotypic coefficient of variation and genotypic coefficient of variation were observed for plant height, leaf breadth, leaves per plant, leaf stem ratio and green fodder yield. High heritability coupled with high genetic advance was observed for plant height, leaf area, stem girth, leaves per plant, leaf stem ratio and green fodder yield. Based on D2 – Statistics, 30 genotypes were grouped into six clusters. The highest inter-cluster distance was observed between cluster III and VI followed by IV and VI, indicating genotypes included in these clusters had wide genetic diversity. Genetic divergence and cluster mean indicates maximum heterosis and good recombinants may be achieved in crosses between genotypes of clusters III, IV and VI in varietal improvement programme. Thus, crossing between genetically diverse genotypes of cluster III with genotypes CSV 15, PC 1001, SPV 462, PC 3, SSV 84, PC 8 and cluster VI with genotype HJ 513 are expected to exhibit high heterosis and good recombinants with desired traits.

High Heritability

Vegetable soybean production is dependent on the development of vegetable type varieties that would be achieved by the use of germplasm to evolve new agronomically superior yielding vegetable type with beneficial biochemical traits. This can be accomplished by a better understanding of genetics, which is why the research was conducted to reveal the quantitative genetics of vegetable soybean genotypes. Genetic variability of main morphological traits in vegetable soybean genotypes and their divergence was estimated, as a result of the magnitude of genotypic variation (GV), and phenotypic variation (PV) of traits varied among the genotypes. All traits showed high heritability (h2) associated with high genetic advance percentage mean (GAM). Therefore, these variable traits are potential for genetic improvement of vegetable type soybean. Genetic diversity is the prime need for breeding, and the magnitude of genetic diversity values were maximized among specific genotypes. Eight clusters were found for all genotypes; cluster VIII and cluster I were considered to have the most diversity. Cluster VIII consisted of two genotypes (GM-6 and GM-27), based on the mean outcomes of the high yield attributing traits. Hence, these two (GM-6, GM-27) genotypes can be advanced for commercial cultivation; furthermore, other genotypes can be used as source of breeding lines for genetic improvement of vegetable soybean.

ABSTRACT The intensive cultivation of vegetables with frequent chemical fertilization may cause accumulation of nutrients in the soil. This, in turn, may reduce crop yields and damage the environment due to contamination of ground water and rivers. Thus, to increase the effects of P (0, 100, 200, 300 and 400 kg ha -1 of P2O5) and K (0, 60, 120, 180 and 240 kg ha-1 of K2O) doses on the growth and productivity of radish cultivars (Sakata 19 and Sakata 25) in a soil with high levels of these nutrients, two experiments were conducted in randomized blocks with the factors cultivars and doses arranged in a 2 x 5 factorial design with three replications. Number of leaves per plant, leaf area, shoot and root dry mass, total and commercial productivity, percentage of cracked roots and P and K contents in the plant and in the soil were evaluated. The Sakata 19 cultivar performed better than the Sakata 25 in both experiments. The fertilization with P or K did not influence the growth and the productivity of both radish cultivars. Therefore, both cultivars of radish evaluated do not need to be fertilized with P and K when planted in a Latosol with high levels of these nutrients.

ABSTRACT The objective of this study was to evaluate the growth of crisp lettuce in hydroponic cultivation, following the nutrient film technique (NFT), using optimized mineral and organomineral nutrient solutions. The experiment was set in 8 x 3 factorial scheme, with treatments distributed in randomized blocks and split plots, with three replicates. The plots corresponded to eight nutrient solutions, of which four were mineral solutions with chemical composition suggested by Bernardes, Furlani, Castellane & Araújo and Ueda, and four were organomineral solutions, suggested by this research with chemical composition similar to those of the previously mentioned mineral solutions. The subplots corresponded to three varieties of crisp lettuce: Thaís, Vanda and Verônica. At 25 days after transplanting, the following parameters were evaluated: stem and crown diameter, root length, leaf area and number of leaves. For stem and crown diameters and number of leaves, the mineral solutions promoted the highest means. The mineral solution of Furlani and the organomineral solutions, except the modified solution of Castellane & Araújo, promoted the greatest root lengths. The smallest leaf area was obtained in the organomineral solution of Ueda. The cultivar Verônica had the highest root length and stem diameter.
