    Studies on response of sweet corn (zea mays L.) To micronutrient (mg, zn and b) application
    (Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2017-05-29) Bhangare, Rupali Vitthal; Salunke, V.D.
    The experiment was conducted on experimental site of Wheat and Maize Research Unit, VNMKV, Parbhani during kharif season 2016-17. The soil was medium black with moderate moisture retention capacity. The land having uniform topography was used to study the responses of micronutrient's (Mg, Zn and B) to crop hybrid (Phule Madhu) under irrigated condition, by using soil and foliar application of (Mg, Zn and B) micronutrients in presence of RDF @ 120:60:50 NPK kg/ha. The experiment was laid out in RBD with three replication and ten treatments, T1 (control), T2 (RDF 120:60:50 kg NPK!ha), T3 (RDF +Mg +Zn +B @ 20kg, 20kg, 5kglha) respectively, soil application at the time of sowing), T4 (RDF + Mg @ 20kg/ha, soil application at the time of sowing), T5 (RDF +Zn@ 20 kglha, soil application at the time of sowing), T6 (RDF +B@ 5 kg/ha at the time of sowing), T 7 (RDF +Mg + Zn+ B foliar application @ 1% at 30 & 45 DAS), T8 (RDF +Mg foliar application @ 1% at 30 & 45 DAS), T9 (RDF+ Zn @ 1% foliar application at 30 & 45 DAS) and T10 (RDF+ foliar application ofB@ 1% at 30 & 45 DAS). The biometric observations i.e. plant height at flowering and harvesting (em), chlorophyll index (SPAD), initial & fmal plant count (m2 ), days to 50 % tassels & silk (DAS), cob height (em) at flowering & harvesting, leaf area ( dm2 ) at flowering & harvesting and the yield parameters green cob weight with husk I without husk at harvest (kg/plot), cob length (em), cob girth (em), green cob sweetness (brix reading %) and cob yield ( qtlha) at harvest. The maximum cob yield The maximum cob yield was recorded by treatment T7 (436.80 q ha1 ) with the application of 120:60:50 kg NPK!ha and spraying of Mg+ Zn+ B@ 1% at 30 and 45 DAS) (41.93 kg plof 1 and 436.80 q ha- 1 ) which was at par with treatment T 8 (RDF+ Foliar application of Mg @ 1% at 30 & 45 DAS) (36.42 kg plof1 and 379.39 q ha-l) and significantly superior over rest of treatments.

    Effect of bioregulators on growth and yield of green gram (vigna radiata l.wilczek)
    (Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2017-07-15) Devgune, Vaishali Maruti; Shinde, S.S.
    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.

    Studies on physiological and biochemical changes during seed storage in soybean (glycine max l. merrill)
    (Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2017-05-30) Bhullarkar, Sony Balchander; Dalvi, D.G.
    An investigation entitled “Studies on physiological and biochemical changes during seed storage of Soybean (Glycine max L. Merrill)” was undertaken to in view of the objectives i.e. (1) to study the effect of genotypes on yield and seed storability in soybean, (2) to study the physiological changes during seed storage and (3) to study the biochemical changes during seed storage. The experiment was carried out in different during July 2016 to May 2017 at Vasanthrao Naik Marathwada Krishi Vidyapeeth, Parbhani. To study the effect of genotype four soybean cultivars viz., MAUS - 71, MAUS - 81, MAUS - 158 and MAUS -162 were sown in five replication as per recommedation in Kharif 2016 and observed for different growth and yield characters. The results revealed that the variety MAUS-158 and MAUS-162 fallowed by were found to be the most ideal for yield and storability. The variety MAUS-81 was found most unstable nature for yield performance. To study the physiological changes during seed storage and to study the biochemical changes during seed storage, the soybean seed of varieties MAUS - 71, MAUS - 81, MAUS - 158 and MAUS -162 were stored in cloth bag, gunny bag and High Density Poly Ethylene bags. The monthly observations for different seed quality parameters were taken during storage. Among the varieties, It was also seen that the variety MAUS - 162 fallowed by MAUS - 158 and MAUS - 71 were better stored than the variety MAUS - 81. It was also noticed that the storage of seed in High density Poly Ethylene bag had significantly increased the storability of soybean seed over the seed stored in gunny bag and cloth bags. The physiological and biochemical components i.e. germination, root-shot length, vigour index, dry matter content viability as tested by TZ test, protein content, oil content were found to be decreased, whereas moisture content and electrical conductivity increased during storage, as the storage period advances irrespective of the varieties and storage containers. In general it could be stated that the germination above Minimum Seed Certification Standard (70%) was maintained upto 10, 9, 9, and 6 months in variety MAUS -162, MAUS -158, MAUS -71 and MAUS -81 respectively. However, the seed stored in HDPE bag and gunny bag was successfully maintained one month more MSCS than the seeds stored in cloth bags irrespective of varieties.

    Effects of micronutrients on growth and yield of soybean (Glycine max L.)
    (Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2017-08-18) Bokse, Manoj Maroti; Bhadarge, H.H.
    A field experiment entitled “Effects of micronutrients on growth and yield of soybean (Glycine max L.)” was conducted during kharif 2016 at Instructional Farm, Department of Agriculture Botany, Vasantrao Naik Marathwada Agriculture University, Parbhani. The experiment was laid out in randomized block design with three replications and ten treatments. The micronutrients, sulphur (22.22, 33.33 and 44.44 kg/ha), boron (11.11, 16.66 and 22.22 kg/ha), and zinc (1.111, 1.481 and 1.851 kg/ha) concentrations were applied as soil application at 30 DAS. Application of micronutrients (sulphur, boron and zinc) increased the plant height. The number of branches increased significantly with micronutrients. The micronutrient treatments significantly increased number of leaves, leaf area, leaf dry weight, dry weight of stem with pod, total dry weight and days to 50% flowering. The growth parameters viz., AGR, RGR, NAR, and LAI increased significantly due to micronutrients application. Biochemical parameters viz., total chlorophyll content (50.15%), protein (42.00%) and oil content (21.00%) were significantly higher with the application of boron (22.22 kg/ha). The number of pods per plant, number of grains per plant (70.33 ), seed yield per plant (8.44 g), seed yield per plot (0.832 kg), seed yield per hector (33.00 q), hundred seed weight (12.00 g), straw per plant (18.56 g) and harvest index (45.50 %) increased significantly due to micronutrients application at concentration (boron 22.22 kg/ha). The application of boron (22.22 kg/ha) recorded significantly highest seed yield in the soybean genotype MAUS-158.
