Study of Genetical Components Determining Vegetative, Flowering and Seed Parameters in Dogflower (Antirrhinum majus L.)
Get PDFField experiment was conducted to elucidate the genetical components forvegetative, flowering and seed characters following Vr-Wr graphical analysis. The studywas carried out in half diallel mating system excluding reciprocals involved 10 inbreds and45 hybrids were developed by crossing inbreds in one direction. The F1s were evaluatedduring 2016-17 and 2017-18 for some of the floricultural important traits. Additive anddominant genetic components were found significant for plant height, number of primarybranches, leaf area index, days taken to flowering, diameter of spike, length of spike, daystaken to seed ripening, number of seeds/pod and weight of seeds/pod in both years exceptnumber of leaves/plant. However, the dominant genetic component was more in magnitudeas compared to additive genetic component. It indicates that dominant genetic variancewas more important than additive genetic variance in determining all the characters exceptnumber of leaves/plant.

Effect of Pretreatment and Packaging Materials on Quality of Spinach Powder During Storage
Get PDFhe study was conducted at School of Agriculture and Environmental Sciences, ShobhitUniversity, Gangoh, Saharanpur, U.P. to evaluate the effect of control sample (unblanched) spinachleaves and hot water blanched sample on shelf-life of spinach powder and to evaluate the effect of watertreatments, chemical composition such as moisture content, fat content and ash content were carried out.Sensory analysis of colour, texture, aroma and overall acceptability were carried out according to 9 pointhedonic scale. To evaluate the shelf-life of spinach powder packed in High Density Polyethylene (HDPE),Low Density Polyethylene (LDPE) and Poly propylene (PP) packaging materials, Total plate count (TPC)and yeast & mould counts were carried out. The results showed that unblanched sample was moresuitable according to fat and ash content. For moisture content hot water blanched sample was morefavourate. PP excelled than HDPE and LDPE as a packaging material to store spinach powder for a longperiod of time. According to sensory score, hot water blanched sample was more favourate by the panelistthan unblanched sample. With increase in storage period TPC and yeast & mould increased but hot waterblanched sample showed less growth of TPC and yeast & mould when compared to unblanched sample.PP showed less microbial count than the HDPE and LDPE, so it is most suitable for spinach powderpackaging for a long period of tim
STUDIES ON EFFECT OF MULCHING ON SOIL MICROBIAL POPULATION IN ACID LIME (Citrus aurantifolia Swingle)
Get PDFAn experiment was conducted at Fruit Research Farm, College of Horticultureand Forestry, Pasighat, Arunachal Pradesh to study the effects of organic and inorganicmulching on soil microbial population in acid lime using Randomized Block Design. Thestudy revealed that the microbial population of the soil was found to be highly significant. Thehighest microbial population count for bacteria was observed in paddy straw mulch (83.45 ×105 cfu/g) followed by rice husk mulch (74.88 × 105 cfu/g) and minimum was found in control(14.06 × 105cfu/g). Likewise, the highest microbial population count for fungi was observed inrice husk mulch (119.34 ×105 cfu/g)followed by paddy straw mulch (54.77 ×105 cfu/g). Thestudy revealed that organic mulching treatment has higher micriobial population as comparedto inorganic mulches which might be due to the supply of large amount of carbon whichserves as a major food source for fungi and bacteri
System of Wheat Intensification Study using Hydroponically raised Wheat Seedling – A New Approach towards Farmer’s Welfare
Get PDF: Wheat is 3rd most consumed crop in India after Rice and Maize. Its production is a source ofemployment for a major part of the country. Inspite of having such high demand Wheat Cultivatingfarmers faces problems like unavailability of irrigation water, poor survival rate, higher diseaseinfestation, poor yields and unhealthy crop. In view of the same System of Wheat intensification (SWI) wasexpected to come out as a possible solution to these problems. In year 2017, Ayurvet Research Foundation,Chidana had conducted a field trial in which Hydroponically (soil- less method of raising crops) raised 8-day old Wheat seedling was transplanted through principle of SWI (through which fixed distance ismaintained between 2 consecutive seedlings which facilitates proper root development and better yields). 4treatments were practiced through which spacing of 10X10cm, 15X15cm and 20X20cm was maintained.Results showed direct yield gain of 18% (2311.1kg/acre) and 13% (2229.3kg/acre) in 10X10cm and 15X15cm spacing as compared to conventional broadcasting method (1956.4kg/acre). The reason for not soconvincing performance of 20X20cm spacing (1766.25kg/acre) was lower plant population though thehighest seed weight of 32.5gm was recorded in 20X20cm treatment.SWI is an efficient technology and can be of great help in doubling farmer’s income. It had reducedweeding, use of pesticides and insecticides. Huge amount of water was saved because of the use ofhydroponically raised Wheat seedling, germination rate was higher, survival rate was higher and thenutritive content of the seeds was way better than the conventional Wheat seeds.Keywords: System of Wheat Intensification (SWI); Hydroponics; soil less technology; System of RiceIntensification (SRI); plant to plant spacing. 
Feasibility and Prospects of Robotics in Agriculture: A Review
Get PDFAchievement of a sustained and equitable development is the main goal of any production and planning system.To keep up with the increasing human population and with the available arable lands, more food production will have to beachieved over the next 50 years. Agriculture and its allied sectors depend simultaneously on both the exploitation andconservation of natural resources. Their impacts on the environment need to be reduced such that it can continue to developsustainable production systems. However, this is rarely achieved. In most of the hilly areas of developing countries, theresources essential to these sectors are threatened by rapid population growth, extreme poverty, loss of biodiversity,pollution of air and water, soil toxicity. In western countries, the adoption of robotics technology has already initiated. Infuture agricultural scenario, it is envisaged that this new and latest technology holds the key to new farming systems toincrease yields and generate income while improving sustainability. Swarm of robots have the characteristics of beingsimplistic and low cost, so that they can be manufactured and deployed in mass without being overly concerned about theirsurvivability. It is a growing industry being put to use in creative ways. The concept has been around for decades, butgroups of small robots working in teams to complete tasks have come in handy on the conservation, sustainability andagricultural front. envisage

Get PDFA field experiment on chickpea (Cicer arietinum) was conducted for threeconsecutive years to study and evaluate the effect of symbiotic N2 fixing bacteria (Rhizobia)with and without symbiotic N2 fixer (Azotobacter) and P solubilizing bacteria an chickpeagrain yield, crude protein content, N, P uptake as also changes in chemical characteristics ofamended alkali soil. The treatment comprised of 8 treatments i.e. T1 control with noinoculation T2, Azotobacter inoculation T3 P.S.B. inoculation, T4 Rhizobia, inoculation, T5Rhizobium +PSB, T6 Rhizobium + Azotobacter T7 Azotobacter + PSB, T8 Rhizobium +PSB+ Azotobacter. Three years observation clearly revealed significantly high nodulationand grain yield were recorded in combined inoculation treatment (Rhizobium +PSB+Azotobacter). Even seed inoculation with Rhizobium and PSB alone, could significantlyincrease the nodule dry weight plant–1and grain yield of chickpea. Similar observations wererecorded in terms of crude protein and uptake of nutrients (N and P). Combined inoculationof chickpea seeds not only increased crop yield significantly but improved soil property interm of pHs ECe dsm–1) and ESP. 
A CRITICAL STUDY ON WEED CONTROL TECHNIQUES
Get PDFWeed is a major problem in crop production, affecting the cropyield as well as the quality of harvested produce. Weeds compete with themain crop for soil nutrients (NPK) of worth Rs 5,000 crores per year in India.The value of total crop losses due to weeds is around Rs. 10,000 crores (Rao,2000). Weed control is one of the most difficult tasks in crop productionagriculture that accounts for a considerable share of the cost involved inagricultural production. There are many methods for weed management, butout of those methods, chemical methods are the most popular. These methodsare hazardous for the environment as well as for human health. To ensurefood security and sustainable development of agriculture, it is criticallyimportant to develop chemical and pollution-free agricultural products. Thisstudy has been carried out to know the different weed controlling techniquesused by the different researchers to be adapted in agricultural wor
