“…The decrease in the weight and length of the silk filament is extreme. From the literature it is inferred that the quantitative as well as qualitative nutrition is highly essential for sericigenous insects to maintain important physiological status and lack of such nutrition in the tasar silkworm might have extended its larval span (Chapman, 1998;Behmer, 2006;Kumar et al , 2010). This is in agreement with the present studies which show an instar-wise extension of larval life span, more so in the fifth instar (Table 1).…”

The commercial rearing of polyphagous Indian tasar silkworm, Antheraea mylitta Drury being practiced on naturally grown primary food plants like Terminalia arjuna, (Arjun) Terminalia tomentosa (Asan), and Shorea robusta (Sal) available in the tropical forests of central India , at times, is seriously affected by the disease-Pebrine, caused by Nosema sp., a microsporidian pathogen. The present investigation on comparative larval, silk gland weight and also cocoon parameters in Pebrine-free and Pebrine-infected ecorace of tasar silkworm Antheraea mylitta Drury (Daba TV), illustrates the tasar silkworm larvae infected with pebrine disease causing heavy losses to the economy of the silk industry. IntroductionThe tropical tasar culture is an important forest based agro-industry of producing vanya silk by rearing a wild silkworm, Antheraea mylitta Drury (Lepidoptera:Saturniidae), primarily on Terminalia arjuna (arjun), Terminalia tomentosa (asan) and Shorea robusta (sal) and secondarily on Lagerstroemia parviflora, Zizyphus mauritiana, Anogeis suslatifolia, Syzigium cumini, Careya arborea and Hardwickia binata, etc. Tasar Culture is "a forest based industry". It plays a major role in improving socio-economic status of tribal, weaker sections, landless people and women.The tasar food plant leaf quality in terms of nutrition can influence the health and growth of larvae, effective rate of rearing (ERR) and crop yields as it has correlation with the weights of cocoon, shell and silk ratio and can influence the crop economics. The leaf nutrient status of tasar food plant is fundamental not only for silk productivity, but also for its metamorphosis during life cycle and subsequent parental moth reproductive efficiency. The larval feeding status of any polyphagous commercial insect has impact on food storage and budgeting for biological activities so as to combat the adverse or to excel during favorable conditions (Reddy et al., January 2012).The diseases in silkworm are the major constraints

“…Infact, nutrients released by organic matter can be slow depending on temperature, oxygen supply, soil moisture, hydrogen ion concentration and inorganic nutrient contents, C/N ratio of the mulched organic matter [19]. This situation can impaired crop nutrition because of delay in nutrients supplying.…”

Abstract-Tropical soils have low fertility and chemical fertilizers are not affordable for most of the farmers, especially in West Africa. The development of low cost technologies for amending agricultural soils in this environment is needed. Biological and organic fertilizers were tested in 20 farmers' fields in central Benin for rainfed rice production on acidic plinthosol under monomodal rainfall pattern conditions. Short time matured cowpea and native grass fallow were preceding NERICA1 and Ina Okpè rice cultivars that are interspecific (Oryza glaberrima × Oryza sativa) and local varieties respectively. Cowpea and bush residues were incorporated into soil before rice seeding. Soil nutrients (C,N,K, Ca and Zn) contents were significantly depleted whereas null balance was observed for soil available-P content. An increased of soil content in Fe (>130 mg kg -1 ) was significantly observed in all the treatments. Highest yield of 1.6 t ha -1 was recorded in the treatment composed of cowpea and NERICA1. The study technology was deemed suitable in deficient-P acid soil whereas the land foot slope position was excluded to avoid potential increasing of Fe content (iron toxicity of rice) in soil of the subsequent lowland. Minimum chemical fertilizer was required for improving rainfed rice cultivation on plinthosol in monomodal rainfall pattern ecology.
