    INFLUENCE OF GROWTH AND CANOPY ATTRIBUTES ON PRODUCTIVITY OF RAINFED GROUNDNUT
    (Acharya N G Ranga Agricultural University, Guntur, 2019) SREELATHA, P; SUDHAKAR, P
    The experiment was conducted under rainfed conditions during kharif 2017 and 2018 in dryland farm, S.V Agricultural College, Tirupati with ten spanish bunch groundnut genotypes of three growth habits of erect (TCGS 894, TAG 24, K6, TMV2, Narayani), decumbent 2 (K9, Kadiri Amaravathi) and decumbent 3 (Dharani, TCGS1157, ICGS 76). Experiment was laid out in randomized block design and replicated thrice. The genotypes were evaluated for canopy attributes viz., plant height, internodal length, number of primary and secondary branches, angle of primary branch with main stem, leaf angle, leaf thickness and pubescence at various growth stages. Interrelation of these canopy attributes with canopy photosynthesis related traits, growth parameters and yield attributes were analyzed. Among the genotypes tested decumbent 3 and decumbent 2 growth habit genotypes recorded ideal range of canopy attributes viz., moderate plant height (36.18 to 36.64 cm), maximum number of primary branches (5.67 – 6.67 ) and secondary branches (5.83 – 6.61), wider angle between primary branch and main stem (81.79o – 86.90o) compared to erect growth habit genotypes. The data on canopy photosynthetic parameters revealed that maximum light was intercepted through the genotypes under decumbent-3 growth habit viz., Dharani (505.55 lux), TCGS 1157 (507.17 lux) followed by D-2 type K9 and Kadiri Amaravathi (432.30 lux). Whereas, lower light interception was recorded by erect genotype TCGS894 (162.67 lux). Similarly, D-3 type xvi Dharani recorded high radiation use efficiency (RUE) in terms of dry matter per unit amount of light interception (6.34 g MJ-1) followed by D-2 types K9 (4.72 g MJ-1) and Kadiri Amaravathi (4.96 g MJ-1). Erect growth habit genotypes recorded lower RUE viz., TCGS 894 (1.21 g MJ-1), Narayani (2.07 g MJ-1), TAG 24 (2.01 g MJ-1) and K6 (1.97 g MJ-1). Consequent to higher light interception and RUE, rate of photosynthesis was also higher in D-3 type Dharani (36.74 µ mol CO2 m-2 sec-1) followed by D-3 type TCGS 1157 (33.73 µ mol CO2 m-2 sec-1) and D-2 type K9 (33.25 µ mol CO2 m-2 sec-1). Mean values revealed that decumbent-3 growth habit types were superior in all photosynthetic attributes, followed by decumbent-2 at grand growth stage i.e. 60 DAS. Total drymatter was also higher in decumbent-3 growth habit genotypes viz., TCGS 1157 (52 g plant-1) followed by Dharani (45.55 g plant-1) and ICGS 76 (44.31 g plant-1). Maximum drymatter partitioning to pod is critical for achieving higher pod yield and decumbent growth habit genotypes TCGS1157 (51.26), K9 (51.26), ICGS76 (49.85), Dharani (47.71) and Kadiri Amaravathi (45.46) found superior than erect types. D-2 type Kadiri Amaravthi recorded higher critical LAI (5.39) followed by D-3 type TCGS 1157 (5.24). D-3 growth habit genotypes maintain higher physiological efficiency in terms of higher mean values of CGR, NAR and LAD throughout the crop growth, followed by D-2 and erect growth habit genotypes. D-3 growth habit genotypes also recorded moderate SLA (151.60 cm2 g-1) along with higher SCMR (44.78) followed by D-2 growth habit genotypes and erect growth habit types which denotes both decumbent types are efficient in maintaining higher WUE than erect types. Mean values of decumbent 3 and decumbent 2 growth habit genotypes recorded higher reproductive efficiency in terms of higher peg to pod ratio compared to erect types and higher yield attributing characters viz., higher number of filled pods per plant, maximum shelling percentage (> 45%) 100 sound kernel weight (> 65 g) and harvest index (46.6) compared to erect types. Consequently decumbent-3 type TCGS1157 recorded higher pod yield of 3760.77 kg ha-1 and it was on par with D-2 type Kadiri Amaravathi compared to best performance of mean of erect growth habit genotypes (2493.06 kg ha-1). The data on correlation studies revealed that plant height recorded significant negative correlation with peg to pod ratio. Number of secondary branches recorded significant positive correlation with rate of photosynthesis, leaf area, total drymatter, leaf area index, leaf area duration, SCMR, yield and yield attributes viz., number of pegs per plant, total filled pods, shelling percentage, 100 sound kernel weight, pod yield, harvest index. Primary branch angle with main stem recorded positive significant correlation with rate of photosynthesis, radiation use efficiency, light interception. Leaf area, xvii total drymatter, CGR, LAI, LAD. Yield and yield attributes viz., number of pegs per plant, total number of filled pods, shelling percentage, 100 sound kernel weight, pod yield. Among canopy attributes of groundnut number of secondary branches and primary branch angle showed to play pivotal role for higher physiological efficiency in groundnut. Based on canopy attributes and their correlation with growth, drymatter and yield characters in groundnut, the ideal plant type attributes for kharif rainfed conditions were described as follows. Medium plant height (35 – 40 cm), wider primary branch angle with main stem (80o to 86o), higher number of secondary branches (5 – 6), maximum critical leaf area index at peg to pod formation stage (4.5 to 5), moderate SLA (180-200 cm2 g-1) and high SCMR (45 – 50) for high WUE, high reproductive efficiency in terms of high peg to pod ratio (> 50), higher drymatter partitioning to pods (> 50%) at pod filling stage and crop duration of 100-110 days.

    ENHANCEMENT OF GERMINABILITY IN SUGARCANE PLANTING MATERIAL THROUGH CHEMICALS
    (Acharya N.G. Ranga Agricultural University, Guntur, 2016) SREELATHA, P; UMAMAHESH, V
    The present investigation was aimed to enhancing sprouting and establishment of bud chips and three budded setts of sugarcane cultivar 2003T121 and 2003V46 variety through various chemical treatments. They were tested for enhancement of germination in different planting materials and to increase the morpho-physiological, growth attributes and various biochemical parameters. The present investigation was carried out at Perumallapalli, ARS, Tirupati, in green house. Experiment was conducted in split plot design with two varieties 2003V46 and 2003T121 were taken as main plot and seven treatments (control, water soaking, cow dung slurry, Ethrel, Calcium chloride, CEPA, CEPA+CaCl2) as subplots. These bud chip raised seedlings were transplanted into field. This experiment was laid out as Randomized Block Design with seven treatments and three replications. The treatments were imposed on the selected two varieties before planting. The germination percentage was increased by different chemical treatments and plant growth regulators which induce the different biochemical parameters and increase the activity of enzymes which were essential for germination. Pre planting sett treatments with different chemicals and waters soaking 24 hrs increases the germination percentage and speed of germination by changing the different biochemical parameters. The study finally reveals that, the morphological parameters viz., shoot length, root length, leaf area, total dry matter, growth parameters (CGR, LAI), biochemical parameters viz., acid invertase, reducing sugars, protein content and non reducing sugars, brix percentage recorded high values in different chemical treatment compared to control . Among the various chemical treatments to improve the sprouting and establishment of bud chips and three budded setts. CaCl2+CEPA, followed by water soaking and calcium chloride showed highest survival percentage, speed of germination and reduce the spread of germination. Different morpho-physiological attributes viz., shoot length, root length, leaf area, number of leaves, number of tillers and total dry matter. Different biochemical parameters viz., acid invertase, reducing sugars, non reducing sugars and proteins were increased by the different chemical treatments. Calcium chloride and 2-Chloroethyl phosponic acid were increase the activity of acid invertase and ATPase. Acid invertase hydrolyze the sucrose in to hexoses that will increase the sprouting and different growth parameters. The present study reveals that, pre planting sett treatments with water soaking or combination of Calcium chloride and 2- chloro ethyl phosponic acid are superior in terms of improvement of survival percentage, seedling vigour index and all morphological characters. Initial growth of the crop established through three budded setts was found better compared to bud chip raised crop.
