    Studies on physiological efficiency of bt cotton hybrids and their non bt counterparts
    (Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2010-05-20) Ghodke, Pranjali Harischandra; Gitte, A.N.
    A field experiment entitled "Studies on physiological efficiency of Bt cotton (Gossypium hirsutum) hybrids and their non-Bt counterparts" was conducted at the farm of Cotton Research Scheme, Marathwada Agricultural University, Parbhani during kharif season, 2009-10. The experiment was sown in simple randomized block design with three replications and six Bt cotton hybrids along with their non-Bt counterparts. Observations on plant height, leaf area, leaf chlorophyll content, relative leaf water content, specific leaf weight, seed cotton yield and its components and length of root and shoot etc were recorded. The hybrid Ajeet 155 Bt out yielded other hybrids owing to moderate leaf area and highest number of bolls per plant, bigger boll size and high harvest index and biological yield was also high. The characters leaf area, number of bolls per plant, biological yield and harvest index showed highly significant positive correlation with seed cotton yield per plant. As a consequence of Bt gene, there was reduction in plant height and increase in leaf area and tqtal dry matter produced per plant. Average of partly red leaves was more in Bt hybrids compared to their non-Bt counterparts.

    The present studies on "Effect of sulphur and boron on physiological growth parameters of soybean (Gly cine ma.'C (L.) MetTill)" involved the study on various physiological aspects were the material used were nine treatments including one control, ' three sulphur with increment dose, three borax with increment and two combinations of sulphur and borax. A wide variation was found for almost all the treatments. Among all the treatments Sulphur @ 40 kg /ha + Borax @ 20 kg /ha showed better performance for all physiological aspects. Observations on yield components shows that number of grains,- number of pods and yield per plant were most important to decide soybean yield. In general growth factors such as AGR, RGR, NAR, LAI and LAD per plant were different during the entire period of crop growth. The total chlorophyll, protein' and oil content maximum in Sulphur @ 40 kg/ha + Borax @ 20 7 kg/ha (T 8) among all the treatments. The treatment Sulphur @ 40 kg /ha + Borax @ 20 kg /ha were superior in these char~cters among all treatments respectively. Therefore yield performance was better in this treatment.

    The field experiment was conducted on field of Depa1iment of Agri l. Botany, College of Agriculture Parbhani, during kharif 20 I 6-17 to study the study "EFFECT OF BIOREGULATORS ON GROWTH AND YIELD OF GREEN GRAM (Vigna radiata L.Wilczek)"The experiment was laid out in randomized block design with seven treatments and three repl ications. The treatments consists of bioregulators viz. , T 0 (Control), T 1 (Salicylic acid 25 ppm), T2 (Salicylic acid 50 ppm), T3 (Eheral 100 ppm), T4 (Etheral 200 ppm), T5 (Cycocel 250 ppm), T6 (Cycocel 500 ppm). Results revealed that the application of plant bioregulators significantly increased morpho-physiological traits viz., plant height, number of branches a compared to control and it reduced the physiological shedding of fl owers and immature pods. Growth parameters viz., leaf area, LAI, AGR, RGR, NAR, CGR were also influenced by the application of bioregul ators. The bio-chemical parameters viz., chlorophyll content, protein content increased sign ificant ly due to the application of plant bioregulators. Application of bioregulators increased the total dry weight significantly and the total dry weight showed a positive correlation with yield. All the yield contributing characters viz., number of pods per plant, seed yield per plant, seed yield per plot increased significantly due to plant bioregulators. The grain yield was significantly higher with the foliar application of cycocel (500 ppm) fo llowed by cycocel (250 ppm) compared to control.

    Safflower is an important rabi oilseed crop. Safflower has a superior adaptability to scanty moisture conditions. It has been under cultivation in India either for its colored florets and much valued oil. Productivity of safflower needs to be increased as this is a cash crop of small and medium holding farmers. There is urgent need to develop suitable management practices and genotypes to make safflower cultivation a successful proposition under Marathwada region of vertisols. In view of the above, it was felt necessary to study the effect of sowing time and suitable genotype under irrigated conditions. The present investigation has been implemented during rabi season of 2018-19 at experimental farm, Department of Agricultural Botany, College Of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was laid out in split plot design comprising sixteen treatments with four main plots i.e. irrigation applied at stem elongation stage (I1), irrigation applied at branching stage (I2), irrigation applied at flowering stage and Irrigation applied at all three selected stages (control) with 4 sub plots of varieties, i.e., PBNS 12 (V1), PBNS 86 (V2) and Sharda (V3) and PBNS 40 (V4). All the treatments were replicated three times. Well irrigated plants, i.e., irrigation treatment at three selected growth stages (I4) recorded significantly highest plant height, number of functional leaves, leaf area, leaf dry weight per plant, relative water content and chlorophyll content than other irrigation treatment. The yield attributes viz., number of capitula per plant and number of seeds per capitulum were observed significantly highest in irrigation treatment I4 followed by I2. Irrigation treatment at all three selected stages (I4) and irrigation at branching stage (I2) recorded high seed yield, biological yield and oil content. Genotypes, PBNS 12 and PBNS 86 recorded significantly highest plant height, number of functional leaves, leaf area and yield attributes viz., number of capitula per plant, number of seeds per capitulum and seed yield and biological yield than other varieties.

    Germinative evaluation of physiological quality in rabi sorghum (sorghum bicolor (L.) moench)
    (Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2019-05-31) Mohd. Riyaz; Kamble, B.G.
    One of the important basic needs for higher agricultural productivity is physiological quality of seed, which is characterized by viability and vigour. As rabi sorghum (Sorghum bicolor (L.) Moench) is classified as "moderate storer" as its viability fluctuates drastically under warm and humid conditions under hot and humid storage conditions. The present research study was conducted to evaluate rabi sorghum seed material with the objectives to relate field emergence and laboratory evaluation with respect to physiological quality of rabi sorghum, with special reference to germinative evaluation criteria, to study the effect of storage on vigour and viability on rab sorghum seeds. Seeds of rabi sorghum variety, SPV-1411, SPV-1595, CSV-22R, CSV-29R, SPV2407 stored in air tight plastic containers and kept under ambient laboratory conditions. Completely randomized block design was employed with four replications. Various germinative criteria including imbibition rate, standard germination test and vigour indexes were studied. The storage of seeds resulted in deterioration of seed vigour as evident by decline in the various parameters investigated. Considering the field stand establishment (field emergence final count) as dependent parameter and various evaluation criteria as independent parameters the simple linear correlation and regression was done for individual parameters. The most rapid, easy and convenient criterion of seed vigour as reflected in terms of stand establishment (field emergence- final count) in rabi sorghum was imbibition rate after 16 hours (R2 = 0.735). The other significant evaluation criteria for the prediction of seed vigour in rabi sorghum were laboratory germination (particularly final count) and vigour indexes.
