Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    INFLUENCE OF SEED PHYSICO-CHEMICAL PROPERTIES ON BRUCHID (Callosobruchus chinensis L.) AND ITS MANAGEMENT IN GREENGRAM
    (Acharya N.G. Ranga Agricultural University, 2018) KAVITHA, G; SESHA MAHALAKSHMI, M
    The present investigation was carried out by conducting three different experiments under laboratory conditions in Regional AgriculturalResearch Station (RARS), Lam, Guntur andDepartment of Seed Science and Technology, Advanced Post Graduate Centre, Lam, Guntur from August, 2017 to March, 2018.All the experiments were laid out in Completely Randomized Design with three replications under ambient conditions. The relative preference of twelve greengram genotypes by pulse bruchid, Callosobruchus chinensis, were assessed based on the biological parameters viz., oviposition, adult emergence, mean developmental period and growth index of the test insect and weight loss of seed under no-choice test. The biological parameters of the test insect after artificial infestation were initially low but gradually increased with increase in period of storage upto eight months. The results revealed that PM-5 was less preferred, while WGG-42 was highly preferred by the pulse bruchid. Based on growth index of insect, five greengram genotypes viz., PM-5, LGG-610, LGG-607, GGG-1 and LBG-595 were categorized as resistant, one as moderately susceptible and the remaining six as highly susceptible to pulse bruchid. Studies on the influence of artificial infestation by pulse bruchid revealed significant differences for germination, seedling parameters and electrical conductivity of seed leachates among the twelve greengram genotypes throughout the storage period of eight months. PM-5 recorded highest germination, seedling length, seedling vigour index and moisture content and lowest electrical conductivity, while WGG-42 recorded lowest germination, seedling length, seedling vigour index and highest moisture content and electrical conductivity through out the storage period. The physical parameters of seed were evaluated for all the twelve greengram genotypes viz., colour, shape, surface texture, seed length and width, seed coat hardness and 100 seed weight. From the data, it was evident that the greengram genotypes with smooth texture, oblong or globose shape and light coloured seed might be less preferred xv by the pulse bruchid for egg laying. The genotype, PM-5 with more length (4.77 mm), width (3.77 mm), length width ratio (1.26) and seed coat hardness (96.00%) recorded less number of eggs, long mean development period and less seed weight loss. Test (100 seed) weight of greengram genotypes under study was highest in PM-5 (4.87 g) and it was observed that test weight had non-significant influence on the incidence of pulse bruchid. Biochemical parameters viz., protein content, phenol content and sugar content were estimated from all the twelve greengram genotypes before and after eight months of storage after artificial infestation by pulse bruchid. The data showed that PM-5 having low sugar and protein content and high phenol content was resistant, while WGG-42, with high sugar and protein contents and low phenol content was susceptible to pulse bruchid. The correlation studies between biological parameters of insect and physical and biochemical characters of seed showed that biological parameters i.e., number of eggs, adult emergence and growth index had significant positive association with protein content, sugar content, moisture content and electrical conductivity and negative correlation with phenol content, 100 seed weight and seed coat hardness. In contrast, mean development period of pulse bruchid had negative correlation with protein content, sugar content, electrical conductivity and moisture content and positive association with phenol content, 100 seed weight and seed coat hardness. Multiple linear regression studies revealed that all the physical and biochemical properties of seed together contributing to a large and significant variation in growth and development of pulse bruchid. The breeder seed of greengram variety, LGG-460, treated with six botanicals viz., turmeric powder @ 20 g kg-1, neem leaf powder @ 25 g kg-1, neem seed kernel powder @ 5 g kg-1, coconut oil @ 5 ml kg-1, inert dust @ 5 g kg-1 and fly ash @ 10 g kg-1 and malathion dust (recommended insecticide) @ 1 g kg-1 (check) along with untreated control seed was used to evaluate their efficacy as seed protectants against pulse bruchid.All the seed protectants used in the present study were significantly superior to untreated seed and were able to protect the greengram seed upto eight months of storage. Highest mortality of adult beetles, lowest number of eggs, adult emergence and seed weight loss were recorded from seed treated with coconut oil and malathion. Among the different seed protectants, turmeric powder and fly ash registered the lower mortality of adult beetles, highest number of eggs and adult emergence. Irrespective of the seed protectants used for seed treatment, the seed quality parameters like germination, seedling length and seedling vigour index decreased, while electrical conductivity and moisture content increased progressively over the period of storage. All the seed protectant treatments significantly improved the germination and seedling growth compared to that of untreated seed through out the storage period of eight months. However, non-significant variation in seed moisture content was observed between the seed treatments. Among the seed protectants evaluated, highest germination, seedling length and seedling vigour index and lowest electrical conductivity and moisture content were recorded in seed treated with botanical product, coconut oil @ 5 ml kg-1which was found as effective as insecticide check, malathion dust @ 1 g kg-1.
