    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) NAGARAJU, S; Dr. K. L. NARASIMHA RAO
    The present investigation entitled “Physiological effects of Boron, Brasssinosteroid and Salicylic acid on drymatter partitioning and yield of chickpea (Cicer arietinum L.)” was undertaken at the Agricultural College Farm, Bapatla during rabi 2013-14.The experiment was laid out in randomized block design with eight treatments viz., Brassinosteroid @ 1ppm at 25DAS (T1), Salicylic acid @ 20ppm at 35DAS (T2), Borax @ 0.25% at 45DAS (T3), Brassinosteroid @ 1ppm at 25DAS + Salicylic acid @ 20ppm at 35DAS (T4 ), Brassinosteroid @ 1ppm at 25DAS + Borax @ 0.25% at 45DAS (T5), Salicylic acid @ 20ppm at 35DAS + Borax @ 0.25% at 45DAS (T6), Brassinosteroid @ 1ppm at 25DAS + Salicylic acid @ 20ppm at 35DAS + Borax @ 0.25% at 45DAS (T7) and Control (T8) in three replications. Among all the treatments, combination spray of Brassinosteroid at 25DAS + Salicylic acid at 35DAS + Borax at 45DAS (T7) exhibited higher performance by increased plant height by 13.9 per cent. The number of flowers developed in to pods per plant was found high with Brassinosteroid, Salicylic acid and Borax sprays, which resulted in an increase of 11.9, 12.0 and 15.9 per cent respectively compared to control. Flower drop and flower abortion were recorded low in plants treated with combination spray of Brassinosteroid at 25DAS + Salicylic acid at 35DAS + Borax at 45DAS. The plants sprayed with Brassinosteroid at 25DAS + Salicylic acid at 35DAS + Borax at 45DAS (T7) increased the accumulation of dry matter in root, stem and leaves by 35, 46.5 and 64.7 per cent respectively compared to control whereas the spray of Brassinosteroid at 25DAS + Salicylic acid at 35DAS + Borax at 45DAS (T7) accumulated 20.16 per cent higher amount of pod dry matter, and 27.14 per cent higher total biomass than control. The higher values of CGR was noticed during 55 DAS – 70 DAS with combination foliar spray of Brassinosteroid at 25DAS + Salicylic acid at 35DAS + Borax at 45DAS (T7) and it was 39.65 per cent higher than control. Maximum RGR was observed during 25-40 DAS with foliar application of Brassinosteroid at 25DAS + Salicylic acid at 35DAS + Borax at 45DAS (T7) by 38.23 per cent compared to control. Brassinosteroid +Salicylic acid +Borax sprays maintained high RWC in leaves. Chlorophyll a, chlorophyll b, carotenoids and total chlorophyll were found higher than control due to spray of combination of Brassinosteroid + Salicylic acid + Borax (T7), followed by Salicylic acid + Borax (T6). Nitrate reductase activity was influenced mainly by Borax spray. The Protein content in seeds was observed 13 per cent higher than control by Brassinosteroid + Salicylic acid + Borax spray (T7).

    EVALUATION OF MAIZE (Zea mays L.) HYBRIDS FOR TOLERANCE TO WATERLOGGING
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) TUFAIL MANZOOR; Dr. K. JAYALALITHA
    A field experiment was conducted at Agricultural College Farm, Bapatla, during kharif 2014 to evaluate the maize (Zea mays L.) hybrids for tolerance to waterlogging. The experiment was laid out in split plot design with two main treatments i.e., control (M1) and waterlogging for six days (M2) and eight maize hybrids as sub treatments in three replications. Waterlogging was imposed at knee height stage i.e. 30 DAS. The soil moisture content of different treatments varied significantly at 36 DAS where the soil moisture content was increased by 44.1 per cent in waterlogging treatment over the control. The findings of the experiment revealed significant differences between waterlogging treatment and hybrids. The growth parameters such as plant height, number of leaves, leaf area and total dry matter and its partitioning measured at different intervals and were significantly affected by waterlogging. Waterlogging resulted in decrease in plant height (15.92 and 16.88 %), number of leaves (15.07 and 18.50 %) at 46 and 90 DAS, respectively over control. The hybrid Lakshmi-2277, maintained higher plant height followed by SY- 280 and Bharati-99 where as CN-117 recorded the lower plant height. The hybrid Lakshmi-2277, maintained higher number of leaves followed by King3063 where as CN-117 recorded the lower number of leaves. Waterlogging decreased the leaf area by 19.19 and 9.16 per cent at 46 and 90 DAS, respectively over control. Waterlogging treatment for six days affected leaf dry matter by 16.71, 11.08 and 25.82 per cent; stem dry matter by 18.97, 16.29 and 15.70 per cent; reproductive parts dry matter by 4.85, 36.25 and 44.37 per cent and total dry matter by 12.68, 23.30 and 33.69 per cent at 46, 90 DAS and at harvest, respectively over control. The hybrid Lakshmi-2277 maintained higher leaf area, leaf, stem, reproductive parts and total dry matter followed by Bharati-99 where as the hybrid CN-117 showed lower value for these parameters. Waterlogging resulted in 50.62% increase in nodes bearing adventitious roots compared to control. Among the hybrids, Lakshmi-2277 maintained higher number of nodes bearing adventitious roots followed by Bharati-99 and SY-280 where as CN-117 showed lower number of nodes bearing adventitious roots. These results also indicated that waterlogging caused increase in ASI by 21.37 per cent over control. Among the hybrids, Lakshmi-2277, showed lower increase in ASI followed by Bharati-99 and SY-280 where as CN-117 showed the highest increase in ASI. Waterlogging treatment resulted in 14.03 and 9.59 per cent decrease in relative water content at 36 and 46 DAS, respectively, over control. Among the hybrids, Lakshmi-2277 maintained higher RWC followed by Bharati-99 and SY280 where as CN-117 showed lower RWC. The results of biochemical parameters indicated that waterlogging decreased the SPAD chlorophyll meter readings, total chlorophyll content and total sugars by 13.38 and 22.98, 20.19 and 14.68 and 20.33 and 21.03 per cent at 36 and 46 DAS, respectively over control. Among the hybrids, Lakshmi-2277 maintained higher values for all these parameters followed by Bharati-99 and SY280 where as CN-117 showed lower values for these parameters. Super oxide dismutase activity was increased by 65.71 and 38.61 per cent at 36 and 46 DAS, respectively over control due to waterlogging stress. The hybrid, Lakshmi-2277, showed higher SOD activity indicating tolerance to excess moisture stress followed by Bharati-99 and SY-280 where as CN-117 showed lower SOD activity. Waterlogging treatment decreased the yield and yield attributes. Cob length decreased by 24.21 per cent, cob girth by 10.37 per cent, cob weight by 37.98 per cent, 100 seed weight by 3.48 per cent, number of kernel rows per cob by 10.43 per cent, number of kernels per row by 29.99 per cent, cob yield by 55.26 per cent and kernel yield by 48.26 per cent. The hybrid, Lakshmi-2277, maintained higher yield and its attributes, apart from higher physiological and biochemical traits followed by Bharati-99 and SY-280 where as CN-117 showed lower values for all these parameters. Hence, Lakshmi-2277 is a superior maize hybrid and possessed waterlogging tolerance traits in addition to high growth attributes and yield followed by Bharati-99 and SY-280.

    MANIPULATION OF SOURCE-SINK RELATIONSHIP THROUGH GROWTH PROMOTERS, MICRONUTRIENTS AND AMINO ACIDS IN BLACK GRAM (Vigna mungo L.Hepper)
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) SOMLA NAIK, R; UMAMAHESH, V
    A field experiment on manipulation of source sink relationship of blackgram through foliar application of amino acids, growth promoting substances, micronutrients and urea either alone or in combinations was conducted at department of Crop physiology S.V.Agricultural college, Tirupati during rabi, 2014. The experiment was laid out in randomized block design with 17 treatments replicated thrice. The treatments used in the experiment was,T1 Glutamine + Arginine; T2 Glutamine; T3 Arginine; T4 Ammonium molybdate + Borax; T5 Ammonium molybdate; T6 Borox; T7 NAA + BAP; T8 NAA; T9 BAP; T10 Ammonium molybdate + Borox + NAA + BAP; T11 Borox+ NAA + BAP; T12 Ammonium molybdate + NAA + BAP; T13 Glutamine + Arginine + Ammonium molybdate + Borox + NAA + BAP; T14 Arginine + Ammonium molybdate + Borox+ NAA + BAP; T15 Glutamine + Ammonium molybdate + Boron + NAA + BAP; T16 Control i.e water spray and T17 was Urea spray. The concentration of the chemicals was fixed irrespective of their usage either alone or in combination. The concentrations used in the experiment were - Glutamine @1000 ppm, Arginine @1000 ppm, Ammonium molybdate @ 0.3 %, Borax @ 0.5 %, NAA @ 100 ppm and BAP @ 50 ppm. In the control treatment 100 % recommended dose of fertilizers was supplied as basal dose and in the rest of the treatments fertilizers were applied @ 75% RDF. The result revealed that Amino acids either alone or in combinations (arginine and glutamine @ 1000 ppm) recorded significantly highest plant height, number of primary branches, number of root nodules, advanced days to 50 per cent flowering, SCMR values, leaf area and total dry matter. Besides a significant increase in reducing, non reducing sugars and per cent protein content in leaf and seeds of blackgram was also observed. Almost a similar result was also recorded with 2 percent urea spray (T17). Increased LAI, LAD and CGR by amino acids and 2 percent urea resulted in higher dry matter production and better partitioning efficiency. Plant growth promoting substances (NAA and BAP) either alone or in combination did not show better results compared to that of amino acids either physiological or in bio chemical parameters. This is due to nitrogen limitation as only 75% RDF was given in basal dose in these treatments. Without proper nitrogen supply NAA and BAP failed to perform their function. However these treatments were found to be on par with control. In the treatments with micronutrient combinations a better result was obtained with ammonium molybdate because of presence of nitrogen in ammonical form. Molybdenum either alone or in combination with boron showed at par result with control for various physiological and bio chemical parameters. T5 Ammonium molybdate@ 0.3 %; T6 Borax@ 0.5 %; T7 NAA @100 ppm + BAP @ 50 ppm; T8 NAA @100 ppm; T9 BAP @ 50 ppm also showed at par result with control. Pod yield plant-1 was found significantly higher in T1 (11.96) compared to that of control (10.5) followed by T3 (11.21), T2 (10.75), T17 (10.67), T4 (10.20), T5 (9.82), T6 (9.71), T7 (9.36) T8 (9.09), T9 (8.89), T11 (8.76) and T10 (7.78). All these treatments were at par with control (10.5). A significant variation among treatments was observed in number pods plant-1 and test weight where as seed number per pod did not differ significantly. A significant difference among various treatments with respect to seed yield Kg ha-1 was recorded. Highest seed yield was observed in T1 (751.3), followed by T2 (709.7), T3 (679.1), T17 (672.5), T6 (645.0), T5 (610.5), T4 (587.8), T7 (572.2), T8 (545.8), T9 (526.1) T10 (501.9) and T11 (506.1). They were found to be at par with control (672.5). Significantly lowest Pod yield plant-1 and seed yield Kg ha-1 was recorded in T15 (7.14 and 467.2) followed by T14 (7.16 and 480.0), T12 (7.75 and 490.56) and T13 (7.60 and 490.2). From the study it was found that T13( Glutamine @ 1000 ppm + Arginine@ 1000 ppm + Ammonium molybdate @ 0.3% + Borox @ 0.5% + NAA @ 100 ppm+ BAP @ 50 ppm) T14 ( Arginine @ 1000 ppm + Ammonium molybdate @ 0.3 % + Borox@ 0.5 % + NAA @100 ppm + BAP@ 50 ppm) and T15 (Glutamine @1000 ppm + Ammonium molybdate @ 0.3% +Boron @ 0.5 % + NAA @100 ppm + BAP @ 50 ppm) showed antagonistic effect on crop growth. This might be due to the incompatible reaction of the components or over dose of their concentrations. The benefit cost ratio of different treatments was calculated. The best ten treatments were found to be T17, T16, T6, T8, T2, T3, T7, T9, T1 and T11 with corresponding values of 3.2, 3.1, 2.9, 2.7, 2.4, 2.3, 2.0, 1.9, 1.8 and 1.6 respectively.
