Lotus Pedunculatus

The development of successful seed production techniques for the recently released tetraploid cultivar of Lotus pedunculatus Cav. (syn: L. uliginosis Schk.; and L. major Scop. Sm.) 'Grasslands Maku' must take account of the distinctive agronomic characteristics of the cultivar. These include slow establishment, particularly in the cool season, slow recovery from defoliation, and poor competitive ability with white clover and other weeds in fertile soils. Spring sowings in cooler areas, a minimum of lenient grazings, and the use of low rates (0.5 to 1.0 kg/ha) of ethofumesate to control white clover in establishing stands are recommended. Although shattering of ripe pods can be reduced by careful harvesting techniques and cutting when 70 to 80% of the pods have turned brown, some loss of seed is inevitable. It is suggested that the cultivar should be grown as a specialist seed crop rather than as part of a dual-purpose grazing and seed-production enterprise. Key words: Seed production, 'Maku' Lotus Pedunculatus, lotus, ethofumesate, seed harvesting, Trifolium repens.

Abstract Knowledge of genetic diversity is crucial to assess the variability of genotypes and their potential use in crop improvement program. The present experiment was conducted at Horticultur Research Station (HRS), Dailekh (1300 masl) for three years during 2016-2018 to study the agro-morphological variability and performance of six genotypes of French bean (Phaseolus vulgaris L.) for pod and seed yield. The genotypes viz; Bhatte, Chaumase, Dhankute Chirrke, WP Con Bean, White OP and Trishuli were experimented in Randomized Completely Block (RCB) design with four replications. Observations were recorded on 14 qualitative and 12 quantitative traits. Among the qualitative traits, French bean genotypes observed variability w.r.t. stem pigmentation, leaf color, leaflet shape, stem hairyness, flower color, pod color, pod shape, pod cross section, pod beak position, pod appearance, seed size, seed shape and seed color. Analysis of variance for quantitative traits showed significant differences among all the genotypes for all the characters studied. Three year mean results showed the genotype Chaumase (35.0 t/ha) followed by Trishuli (28.0 t/ha), WP Con Bean (24.6 t/ha) and White OP (22.9 t/ha) recorded the maximum green pod yield. Similarly, genotypes Chaumase (2.1 t/ha), Trishuli (2.1 t/ha), Dhankute Chirrke (1.44 t/ha) and White OP (1.09 t/ha) were found promising for seed production purpose. The agro-morphological variation observed in growth and pod characters could be utilized in variety improvement programs. Future research work needed to be focused on the further evaluation of these genotypes under different production system for yield and seed production and to identify traits useful for crop improvement.

Development Goals

There is an intrinsic link between the challenge we face to ensure food security through the twenty-first century and other global issues, most notably climate change, population growth and the need to sustainably manage the world's rapidly growing demand for energy and water . Our progress in reducing global poverty and achieving the Millennium Development Goals will be determined to a great extent by how coherently these long-term challenges are tackled. A key question is whether we can feed a future nine billion people equitably, healthily and sustainably. Science and technology can make a major contribution, by providing practical solutions. Securing this contribution requires that high priority be attached both to research and to facilitating the real world deployment of existing and emergent technologies. Put simply, we need a new, ‘green er revolution’. Important areas for focus include: crop improvement; smarter use of water and fertilizers; new pesticides and their effective management to avoid resistance problems; introduction of novel non-chemical approaches to crop protection; reduction of post-harvest losses; and more sustainable livestock and marine production. Techniques and technologies from many disciplines, ranging from biotechnology and engineering to newer fields such as nanotechnology, will be needed.

Sugar Mills

The main purpose of the study was to investigate role of sugar mills in introducing improved production and protection methods for increasing sugarcane yield. Sugarcane farmers and Extension Field Staffs (EFS) in Pakistan are performing laborious jobs but the ultimate production of sugarcane crop is quite low as compared to neighboring countries. The main constraint associated with it is lack of technical competencies in the field of agriculture on the part of farming community and EFS of public and private sectors. There is a dire need to equip them with latest technological advancements in order to cope with changing demand of the country. The operational area of Hussein Sugar Mills (HSM) was selected which consisted of 200 villages. Out of which 4 villages namely chak 53, 54, 55 and 61 were selected randomly. From each village 30 respondents were selected through convenient sampling method. Hence, a total sample of 120 respondents was selected from the related section area of the sugar mill. The data were collected with the help of pre-tested and validated interview schedule. It was concluded that HSM must increase its area of operation as sugarcane growers mostly followed the instructions of EFS of HSM.

The legitimacy of parents and progenies used in crop improvement programmes is vital for any meaningful progress in selection. While acknowledging the shortcomings of controlled pollination in oil palm breeding and commercial seed production, the legitimacy of 20 oil palm progenies from the Nigerian Institute for Oil Palm Research (NIFOR) breeding programme was determined using 16 fluorescently-labeled microsatellite markers. The genotyping of parents and progenies was conducted by capillary electrophoresis using the ABI 3730 DNA Genetic Analyzer (Applied Biosystems, USA). Results revealed a complementary expression of the parents’ alleles in 18 out of the 20 individual progenies screened, confirming their hybridity and genetic identity. The two illegitimate progenies detected could be attributed to pollination and planting errors, respectively. A subset of three sufficiently informative loci (sMg00016, sMg00179 and sMo00102) was identified for routine quality control genotyping. The detection of illegitimate progenies provided ample evidence to substantiate the importance of assessing hybrid fidelity in breeding programmes. Furthermore, the usefulness of microsatellite markers as a reliable technique for routine assessment and unambiguous identification of oil palm crosses was established. The implications of microsatellite- based hybrid identification in oil palm varietal improvement programmes have been adequately discussed.

Restricted Use

The main reason of low production and productivity is restricted use of inputs, notably improved seeds and fertilizers. May vegetable seeds are imported which results in different problems like disease outbreak, timely unavailability, costly and so on. The demand of vegetable seed is increasing from time to time. Though vegetable seed production is difficult, there are attempts and efforts to produce at local level. Strengthening of community based seed multiplication is a means to develop the vegetable seed production techniques and business. In order to bring this to practical, demonstration and scaling up activities conducted since 2009 to 2014. Farmers Research Group (FRG) approach was used to implement the research. In 2013 an average yield of 7q/ha of onion seed was recorded while the maximum was 10 q/ha. While in 2014 a maximum yield 16 q/ha was recorded at farmers field. The yield increment might be due to skill development by the farmers. Farmers could get gross income of 24, 000 thousand from a parcel of 300 m2 land. Thus local seed production practice is technically possible and economically feasible and should be encouraged and promoted by all stakeholders so as to enhance the income and livelihood of farmers.
