Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Evaluation of the productivity of chilli hybrids
    (Department of Plant Breeding, College of Agriculture, Vellayani, 1986) Elizabeth Philipose; KAU; Manikantan Nair, P
    A study was conducted at College of Agriculture, Vellayani, for evaluating the productivity of six intervarietal chilli (Capsicum annuum L.) hybrids obtained by crossing four inbreds in all possible combinations without reciprocals. Since the germination of the combination PR x PCl was poor, the other five hybrids along with four parents were evaluated in a 9 x 3 RED during 1984-85 and 1985-86. Observations on twenty quantitative and five five qualitative attributes were recorded. The statistical analysis included analysis of variance , pooled analysis and the estimation of genetic parameters, correlations among sixteen quantitative traits and three types of heterosis namely relative heterosis, heterobeltiosis and standard heterosis

    Breeding behaviour of interspecific hybrids in the genus Arachis L.
    (Regional Post Graduate Training Centre, Agricultural College and Research Institute, Coimbatore, 1962) Gopinathan Nair, P; KAU; Ponnaiya, B W X
    The investigation aims at a comparative study of two kinds of F2 populations. The first one was derived from hybrids between two tetraploid parents, namely A-hypognea and A.sp (A.354) whose genomes are homologous. The second typeof tetraploids were derived from back cross hybrids between A-hypognea and allotriploid (resulting from the cross A-hypognea X A.sp. (A.329)). A comparative morphological and cytological analysis of these F2 populations have been made. Special techniques such as Hybrid index method and Polygraphic analysis were adopted and the variability expressed in the two F2populations have been eveluated. The possible causes for the occurrence of a skewed recombination in the straight F2 population have been suggested.

    Pollination, pod set and compatibility studies in open pollinated progenies of cocoa var. Forastero
    (Department of Plant Breeding, College of Horticulture, Vellanikkara, 1984) Madhu, P; KAU; Kumaran, K
    Investigations were carried out at the College of Horticulture Vellanikkara, Thrissur, to study the polination , pod set and compatibility aspects of open pollinated progenies of cocoa, var. Forastero. It was found that eventhough cocoa flowered thoughout the year, maximum flower production was between November and April. The flower opening was a slow process starting from 2 to 4 pm and lasting upto 2 to 4 pm on the subsequent day . Maximum stigma receptivity was found between 10 am and 12 Noon. Natural pollination was through the agency of insects. By controlled pollination there was 48 per cent increase in the pod set. Hand pollination by forceps was found to be the best method of artificial pollination. A large number of pod set was not carried to maturity due to the incidence of cherelle wilt. The loss due to Cherelle wilt ranged from 37.04 percent to 70.37 per cent. Most of the trees studied were self-incompatible , while two of them were self compatible. The self - incompatibility in the materials investigated herein could be exploited for production of hybrid pods.

    Cross compatibility between abelmoschus esculentus and abelmoschus manihot and hybrid sterility
    (Department of Plant Breeding, College of Agriculture, Vellayani, 1986) Prabha, P; KAU; Gopakumar, K
    Observations made during 1985, while conducting a breeding experiment on interspecific hybridization in the genus Abelmoschus of family MALVACEAE, reveal that the virus caused Yellow Vein Mosaic disease susceptible bhindi varieties of the cultivated species esculentus cross readily with the resistant wild/ semi-wild species manihot. Absence of interspecific mating incompatibility is of advantage in programmes of breeding for evolving improved varieties of the crop with built-in-resistance. The first generation hybrids though do not produce viable seeds in profusion, are not totally sterile. The scanty viable seed recovery from the hybrids against the parents is suspected to be due to chromosomal differentation that could have taken place during speciation in the genus

    Progeny studies in west coast tall coconut palms of different yield groups
    (Department of Plant Breeding, College of Agriculture, Vellayani, 1982) Bindu, M; KAU; Gopakumar, K
    Observations made during 1981-82, while conducting a Systematic Pedigree Progeny Analysis at the Coconut Research Station, Balaramapuram, on the coconutpalm, variety West Coast Tall, belonging to the categories of Low, Medium and High yielders, yielded valuable information so as to ensure realization of the desired effect in inducing an overall enhancementin the late stage seedling progeny performance standards. Earlier recommendations stressed the need for exercising phase protracted selection at the levels of the motherpalm population, seednuts and the seedling progeny stand in the nursery, on specified norms. The findings of this study help to develop a more reliable methodology for identifying distinctly, the vigorous from the less vigorous among the seedling progeny.

    Investigations on the effects of X-rays on Cowpea (Vigna sinensis L. SAVI.)
    (Division of Agricultural Botany, Agricultural Botany, Agricultural College & Research Institute, Vellayani, 1964) Ravindran Nayar, P N; KAU; Kumara Pillai, P
    This thesis embodies the results of an investigation carried out to study the effect of X-rays on the common cowpea (vigna senensis). A pure variety of cowpea (African) was selected , dry and pre soaked seeds of which were treated with X-raysat the following doses: 1000, 3000, 5000, 7000, 9000, 11,000, 13,000 and 15,000 r. units. Germination, survival of plants, chlorophyll and other morphological abnormalities, growth of plants, pollen sterility, flower production, fruit set, average seeds per pod and 1000 seed weight were studied. The frequency of abnormal anaphases were studied from root tip squashes. Regression analysis was carried out for almost all obsevations to establish the relationship between doses and the different characters observed.
