Amongst forty six chilli germplasms screened against yellow mite BCCH-SL-4 was found to be the least susceptible to yellow mite (1.5 mite/leaf) followed by SB-6-2-1 (2.8 mite/leaf). DS-1-2 (16.50 mite/leaf) and FL-1-2 (13.50 mite/leaf) were most susceptible against yellow mite. The highest yield was also obtained from BCCH-SL-4 (8.40 t/ha). Application of Dicofol 18.5 EC @ 2.5 ml/lit., spiromesifen 22.9% EC @ 1 ml/lit and diafenthiuron 1g/lit was significantly superior to other treatments.

The critical limit of boron (B) in soils and plants was determined through a pot culture experiment with 22 acidic soils of terai zone of West Bengal. The hot water soluble B in these soils was found to be positively and significantly correlated with pH, organic carbon, and per cent dry matter yield of rice, B concentration in plant tissues and B uptake by shoots. The critical concentration of soil available B and plant tissues B worked out to be 0.32 and 12.5 mg kg1, respectively below which appreciable responses to B application were observed. The average dry matter yield increased with increasing level of B application up to 1.5 mg kg1. The response to B application in rice on B-deficient soils was found to be 88.4%.

Despite the devastating effect of suicide on numerous lives, there is still a lack of knowledge concerning its neurochemical aspects. There is increasing evidence that brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are involved in the pathophysiology and treatment of depression through binding and activating their cognate receptors TrkB and TrkA respectively. The present study was performed to examine whether the expression profiles of BDNF and/or TrkB as well as NGF and/or TrkA were altered in the hippocampus of postmortem brain of the participants, who had committed suicide and whether these alterations were associated with specific psychopathologic conditions. These studies were performed on the hippocampus of 21 suicide victims and 19 non-psychiatric control individuals. The protein and mRNA levels of BDNF, TrkB, NGF, and TrkA were determined by sandwich enzyme-linked immunosorbent assay, Western blot and reverse transcription-PCR. Given the importance of BDNF and NGF and their cognate receptors in mediating physiological functions, including cell survival and synaptic plasticity, our findings of reduced expression of BDNF, TrkB, NGF, and TrkA on both the protein and mRNA levels of postmortem brains of suicide victims suggest that these molecules may play an important role in the pathophysiological aspects of suicidal behavior. © the author(s), publisher and licensee Libertas Academica Ltd.

Dissipation kinetics of two systemic fungicides, namely fluopicolide and propamocarb used as a combination formulation (Infinito 68.75 SC), were studied on tomato at four different locations by the All India Network Project on Pesticide Residues to recommend their pre-harvest interval (PHI) and to propose the maximum residue limits (MRL) for the two fungicides based on chronic hazard exposure assessment. The combination fungicide was sprayed thrice at the recommended dosage of 93.75g a.i./ha fluopicolide and 937.50g a.i./ha propamocarb as well as at double the recommended dosage of 187.50g a.i./ha fluopicolide and 1875.0g a.i./ha propamocarb on tomato crops and the residues were monitored periodically by GC-MS. The fungicides dissipated to below the limit of quantification (LOQ) within 10 to 15days, with a half-life of 2-4days for fluopicolide and 1-2days for propamocarb. Taking into consideration the MRLs of codex and calculations made using the method of MRL fixation of the Food Safety and Standard Authority of India (FSSAI) as well as the Organization for Economic Co-operation and Development (OECD) calculator, MRL of 5mg/kg is proposed for fluopicolide and 15mg/kg for propamocarb, following critical exposure of the commodity considering PHI of 1day.

Insect pests are the main limiting factor for vegetable production in India and tropical Asia, amongst which Lepidopteran pests cause a significant amount of damage. Vegetables are some of the most profitable crops and farmers everywhere feel the need to protect such high value crops from any type of damage caused by insect pests. They often use synthetic insecticides indiscriminately, and insect resistance to insecticides is very common. Lepidopteran pests such as diamond-back moth (DBM) on cabbage (Plutella xylostella), fruit borer on tomato (Helicoverpa armigera), pod borer on chilli (Spodoptera litura), shoot and fruit borers on brinjal (Leucinodes orbonalis) and okra (Earias fabia) are among the major pests of vegetables. To control Lepidopteran pests efficiently, some new pesticides, with novel modes of action, have been developed recently. To determine the effectiveness of the new pesticides compared with traditional chemicals (chlorpyrifos+cypermethrin), five field experiments were done on brinjal, okra tomato, cabbage and chilli, over two seasons. Altogether nine pesticides (flubendiamide, spinosad, emamectin benzoate, chlorfenapyr, Bacillus thuringiensis, novaluron, lufenuron, methoxyfenozide and mixed formulations of chlorpyrifos+cypermethrin) were used with untreated controls. All other agronomic practices were standard, and a blanket spray to control sucking pest insects and mites was applied when necessary. Results showed that flubendiamide, spinosad and chlorfenapyr were highly effective in reducing the damage caused by diamond-back moth on cabbage, fruit borer on tomato, pod borer on chilli, shoot and fruit borer on brinjal and shoot and fruit borer on okra, and led to increases in yield. Novaluron was most effective against pod borer on chilli, closely followed by spinosad, flubendiamide and chlorfenapyr. In the case of fruit borer on tomato, spinosad was the most effective. Shoot and fruit borers on brinjal and okra were also controlled effectively by flubendiamide, spinosad and chlorfenapyr. Emamectin benzoate methoxyfenozide, and Bacillus thuringiensis, also performed well in reducing damage and increasing yield. Bacillus thuringiensis and methoxyfenozide were, however, less effective against shoot and fruit borer on brinjal and okra. The new pesticides, with novel modes of action and high selectivity, were highly effective against Lepidopteran pests. They are safer to non-target organisms and quickly degrade to non-toxic products.

The main objective of this study was to identify the best date of sowing and soil moisture content at different soil depths to get the highest seed production for fenugreek. Plots were planted for 2 years (2012–2013 and 2013–2014) at the following sowing dates: 2nd, 9th, 16th and 23rd and 30th November (D1, D2, D3, D4 and D5). It may be concluded that to obtain higher seed yield, fenugreek should be sown earlier at 2nd November and irrigation should be given in all the major growth phases at seedling, branching, flowering, pod formation and pod development stages. © 2016, The National Academy of Sciences, India.

Field studies were undertaken for two consecutive seasons to evaluate the bioefficacy of cyazypyr 10% OD, a new molecule belonging to anthranilic diamide group of insecticides, along with imidacloprid 17.8% SL and fipronil 5% SC as standard checks, against the insect pest complex of tomato vis-à-vis its impact on natural enemies and crop health. The toxicity of cyazypyr 10% OD and four other molecules, each at two doses (diluted in 600l water), against the pupal stage of Trichogramma pretiosum Riley, an important egg parasitoid of Helicoverpa armigera Hubn., was evaluated in the laboratory. Cyazypyr 10% OD @ 90 and 105 g a.i./ha was highly effective in controlling the fruit borer, Helicoverpa armigera Hubn., aphid, Aphis gossypii Glov. and white fly, Bemisia tabaci Gen., and increasing the yield of marketable fruits. This insecticide @ 60-105 g a.i./ha effectively controlled the leaf miner, Liriomyza trifolii Burg. Imidacloprid 17.8% SL @ 22.5 g a.i./ha and fipronil 5% SC @ 60 g a.i./ha were also highly effective in controlling the pests. Considering the bioefficacy and yield, cyazypyr 10% OD @ 90 g a.i./ha may be recommended for effective control of pest complex of tomato. Cyazypyr 10% OD @ 45-105 g a.i./ha did not significantly reduce the field population of natural enemies and was safe to the crop even @ 360 g a.i./ha. In laboratory test, cyazypyr @ 90 and 60 g a.i./ha found to be safe to T. pretiosum Riley pupae, causing only 23.17 and 20.73% mortality, respectively.

In order to study the effects of sowing dates on phenology and yield of coriander (Coriandrum sativum L.), an experiment was conducted during 2010-2012 based on a randomized complete block design with three replications in HRS, Mondouri, BCKV, India. Six sowing dates included 5th November (D1), 12th November (D2), 19th November (D3), 26th November (D4), 3rd December (D5) and 10th December (D6). The results showed that a delay in sowing from November 5 to December 10 decreased plant height, number of primary branches per plant, days to 50% germination, days to flower initiation, days to 50% flowering and days to fruit maturity significantly. The 5th November exhibited significant improvement in yield attributes namely numbers of umbels per plant (25.58), umbellets per umbel (6.85), seeds per umbel (30.55), test weight (12.61 g), seed weight per plant (6.85 g) and seed yield ha-1 (1098.33 kg ha-1). © 2014 Academic Journals Inc.

An experiment was conducted to study regrowth and yield of coriander influenced by nitrogen (N) with five different urea doses (0, 1.5, 2.0, 2.5, 3.0% by volume) as foliar spray. Spraying of urea has a significant impact on growth and yield in the second cut. Leaf emergence rate (LER) was higher during initial growth phase and then drastically reduced until first cutting, whereas the stem elongation rate (SER) recorded its peak value during 75-105 DAS. Impact of foliar spray was conspicuous during the later phase of regrowth with the treatment of 2.5% urea achieving the highest SER. Additional return due to spraying was positive up to a dose of 2.5% urea and decreased thereafter. Hence, the study indicated that a foliar spray of nitrogen (2.5% urea) may be beneficial for coriander leaf production under multicut system and the crop is sensitive to rainfall, phototemperature, and morning humidity. © Taylor & Francis Group, LLC.

Background: Recent research on nanoparticles in a number of crops has evidenced for enhanced germination and seedling growth, physiological activities including photosynthetic activity and nitrogen metabolism, mRNA expression and protein level, and also positive changes in gene expression indicating their potential use in crop improvement. We used a medicinally rich vegetable crop, bitter melon, as a model to evaluate the effects of seed treatment with a carbon-based nanoparticle, fullerol [C60(OH)20], on yield of plant biomass and fruit characters, and phytomedicine contents in fruits.Results: We confirmed the uptake, translocation and accumulation of fullerol through bright field imaging and Fourier transform infra-red spectroscopy. We observed varied effects of seed treatment at five concentrations, including non-consequential and positive, on plant biomass yield, fruit yield and its component characters, and content of five phytomedicines in fruits. Fullerol-treatment resulted in increases up to 54% in biomass yield and 24% in water content. Increases of up to 20% in fruit length, 59% in fruit number, and 70% in fruit weight led to an improvement up to 128% in fruit yield. Contents of two anticancer phytomedicines, cucurbitacin-B and lycopene, were enhanced up to 74% and 82%, respectively, and contents of two antidiabetic phytomedicines, charantin and insulin, were augmented up to 20% and 91%, respectively. Non-significant correlation inter se plant biomass, fruit yield, phytomedicine content and water content evidenced for separate genetic control and biosynthetic pathways for production of plant biomass, fruits, and phytomedicines in fruits, and also no impact of increased water uptake.Conclusions: While our results indicated possibility of improving crop yield and quality by using proper concentrations of fullerol, extreme caution needs to be exercised given emerging knowledge about accumulation and toxicity of nanoparticles in bodily tissues. © 2013 Kole et al.; licensee BioMed Central Ltd.
