Indian processed vegetables in International markets accelerate the growth of Indian economy. Studying the changes in share of processed vegetables to different countries, improve the welfare of farmers, processers and exporters. In this regard, an attempt was made to quantify the changing structure of Indian processed vegetables exports. The main objective of the present study was to analysis the growth and the direction of trade in processed vegetables export. In this regard, secondary data, mainly quantity of processed vegetables exports from India was collected from APEDA, for a period of 1995-96 to 2017-18. Growth rates was estimated by using the exponential growth model and the Markov chain analysis model was computed through linear programming method to assess the transition probabilities for the major Indian processed vegetables export markets using Lingo Programming computer package. Accordingly, processed vegetables export market have positive double digit growth rate, UK retained 22.5 per cent, countries pooled under ‘others category’ retained 32.4 percent of share of Indian processed vegetables export. That the countries pooled under ‘others category’ and UK would be the more stable importers of the processed vegetables from India in future and country like Germany and Netherland was not found as the stable importer.

The present investigation was carried out to study the efficacy of different novel insecticides and bio-pesticides against stem borer Scirpophaga incertulus (Walker) during kharif 2015-16 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Efficacy of newer insecticides (fipronil 5 SC, cartap hydrochloride 50SP,chlorpyriphos 20 EC, imidacloprid), one biopesticide (Neemarin 1500 ppm) and one bio-control agent (Trichogramma japonicum) were evaluated against yellow stem borer Scirpophaga incertulas (Walk.) in Basmati rice. The stem borer recorded as dead heart ear heads ranged from 4.85 to 10.55 per cent and white ear head showed that it was recorded on 38th standard weak. All the treatments were found significantly effective in reducing the infestation of stem borer and increasing the yield compared with control. Application of fipronil 5 SC was the most effective treatment in reducing the stem borer infestation at all observational interval resulting highest grain yield The results of paddy yield depicted in table 3, showed that the plots treated with fipronil 0.3 GR @ 25 kg/ha gave the highest yield (45.56 q/ha).

A study was conducted in vitro condition to analyse the morphology and efficacy of bio agent, plant extract and some chemical against P. mangiferae which was collected from different districts of Manipur. The morphological characters under study consist of colony and conidial characteristics such as colour, shape, size and appendages. The cultural growth colour of P. mangiferae on PDA varied from concolour to versicolour fuliginous. The conidial shape varied from oval and spherical to elliptical with prominent appendages. The conidial length and widths were 22.9 and 5.7 μm respectively. The diseased sample which was collected from different district of Manipur consists of three septation and the number of conidial appendages was found 2-3 numbers. Among seven antagonists namely Penicillium citrinum, Trichoderma atroviride, T. ovalisporum, Hypocrea lixii, T. harzianum (69 and 131) and T. asperellum evaluatedin vitro, T. asperellum showed the best in inhibiting the growth of the fungus (85.8%). Among three plant extracts viz. garlic, neem and sweet flag evaluated in vitro, garlic extract (3.0%) showed the best result (100.0%). Among the seven chemicals viz. carbendazim, thiophenate methyl, mancozeb, imidacloprid, fipronil, profenophos and thiomethoxam evaluated in vitro, thiophenate methyl (0.05%) and carbendazim (0.05%) showed the best result with 100.0 percent inhibition in fungal growth.

The present investigation had shown the genetic analysis of different agronomic characters as well as quality traits in linseed of six parents were evaluated in 2009-10, during rabi season at Students Instructional Farm, C. S. A. University of Agriculture and Technology, Kanpur, U.P., revealed the role of both additive and non-additive gene action for all ten characters through diallel cross analysis. Average degree of dominance showed the presence of partial dominance for all the characters except iodine value which showed over dominance. The proportions of positive and negative effects in the parents were asymmetrical for all the characters. The ratio of dominant and recessive alleles in parents (KD/KR), indicated the dominant alleles were more frequent than recessive alleles for the characters, number of capsules per plant, days to maturity and iodine value in F1 and days to flower in F2 generation. Characters, plant height, number of primary and secondary branches per plant, 1000-seed weight, seed yield per plant and oil content in both F1 and F2 generations showed that recessive alleles were more frequent determining the extents of genetic gain that can be made in particular direction. If the alleles present in the population are predominantly of recessive nature, the extent of genetic advance will be limited. The computed ratio of (ĥ2/Ĥ2) estimate the number of gene groups suggested the preponderance of recessive genes; however they do have dominant genes. ‘t2’ value for uniformly test for Wr, Vr interprets distribution of dominant and recessive genes among the parents by investigating the relations.

The present study was carried out to examine the effect of integrated nutrient management on growth and yield parameters of okra (Abelmoschus esculentus L. Moench) at Horticulture Research Farm, Department of Horticulture, Chaudhary Charan Singh University, Meerut, U.P. during the year 2018. The field experiment was laid out in randomized block design with three replications. The treatments involved in the study were eight in numbers i.e. T1 Control (no fertilizers), T2 (125 kg N + 50 kg P2O5 + 60 kg K2O /ha), T3 (100 kg N + 40 kg P2O5 + 48 kg K2O + 5 t FYM /ha) T4 (100 kg N + 40 kg P2O5 + 48 kg K2O + 12 q VC /ha), T5 (75 kg N + 30 kg P2O5 + 36 kg K2O + 10 t FYM /ha), T6 (75 kg N +30 kg P2O5 + 36 kg K2O + 24 q VC /ha), T7 (25 t FYM /ha), T8 (60 q VC /ha). All variable parameters regarding vegetative and reproductive parameters of okra were significantly influenced by integrated nutrient management practices. Soil of the experimental field was sandy loam and neutral in pH reaction. The present investigation clearly indicate that the combined application of organic and inorganic fertilizers i.e. T6 (75 kg N +30 kg P2O5 + 36 kg K2O + 24 q VC /ha) had the better effect on growth and yield parameters viz., plant height (129.11 cm), number of nodes on main stem (19.23), fresh weight of plant (351.13 g), dry weight of plant (72.12 g), number of pods per plant (16.13), length of pod (15.80 cm) and yield (134.14 q /ha) as compared to other treatments in case of okra cv. Arka Anamika under Western Uttar Pradesh conditions. On the basis of present investigation, it may be concluded that an integrated use of organic manure with chemical fertilizer increased the growth and yield of okra than that of sole application of either chemical fertilizer or organic manures.

Amarsimhas Amarkosa (Namalinganusasanam) is an ancient Sanskrit thesaurus. It has bearing on teaching of Sanskrit but also includes information on nearly all facets of human life inclusive of Indian biodiversity. It is composed of Sanskrit verses which are replete with references to Sanskrit common plant names. The present author assessed these names and equated with Latin plant names and their respective families. This attempt deals only with the exotic plant species to decipher pant invasion in the erstwhile by consulting relevant taxonomic literature. A total of 64 species belong to 58 genera and 37 Angiospermic families. The data accrued is discussed in the light of plant invasion and implications in the then and present India.

Tomato (Lycopersicon esculentum) is highly perishable and has potential for processing industries in bumper producing seasons in Nepal. The study on judicious use of nitrogen and potassium levels was aimed to explore the quality attributes along with the shelf life of tomato fruits. Three levels of nitrogen comprising 0 kg/ha (N0), 100 kg/ha (N100), 200 kg/ha (N200) and four levels of potassium 0 K2O kg/ha (K0), 80 K2O kg/ha (K80), 160 K2O kg/ha (K160), 240 K2O kg /ha (K240) were used as treatments in randomized complete block design with three replications at Chitwan (Inner Terai) Nepal. Tomatoes at breaker stage were harvested from the field and 10 fruits from each treatment per replication were kept for physiological weight loss, color rating and shelf life in ambient condition (17.5±3 0C and 80.5±6.5 % RH). Fruit quality with respect to physicochemical properties like firmness, TSS, TA, pH and Vitamin C was assessed at the end of shelf life. Higher potassium levels hasten color development and increased TSS, firmness and vitamin C content. Physiological weight loss was greatly reduced and extended shelf life was achieved with 100 kg N/ha and 240 kg K2O/ha.

A field experiment conducted for screened 288 germplasm of linseed against bud fly infestation at Kanpur, Uttar Pradesh during rabi season to study the historical basis of resistance of linseed against bud fly. The results indicated that the sepal thickness negative highly significant relationship (r=--0.7224) with bud infestation. The resistant germplasm line maximum sepal thickness (0.49 mm) had relative minimum bud infestation (6.88%) and was statically at par other resistant germplasm lines viz. A-95B, CI-1385, EC-1392, EC-1424, GS-234, IC-15888 and JRF-5. While minimum sepal thickness (0.24 mm) with maximum bud infestation (65.11%) which was statically at par with other susceptible lines viz. Ajgan-3-1, Ajgan-20M, Alipur (Hamirpur), Anand, GS-148, GS-440, Gunawal Local, NP (RR) 193, RAULD-7810, RLC-28 (PM), MS-14, SJKO-2, SJKO-45. The genotypes with minimum thickness of sepal suffered maximum bud infestation as compared to those with maximum sepal thickness.
