Physiological and bio chemical modification through bio inducer in tube rose infected with root knot nematode (Meloidogyne incognita)
The main aim for this study is to investigate on physiological and bio chemical modification through bio inducer in tube rose infected with root knot nematode, Meloidogyne incognita. Two pot culture experiments was carried out during 2015-2018 for assessment of bio chemicals changes induced by selected bio stimulant in tube rose infected with root knot nematode, M. incognita. In this study bulbs of tuberose var. prajwalwas planted at the rate of 1 bulb/pot with three replications and each replication consist of two pots. The juveniles (1juvinile/g of soil) was inoculated under controlled condition. The pots wastreated with ascorbic acid - corm soaking (24hrs)+ foliar spray (45 & 90 DAP) with various concentration viz.,250 ppm,500 ppm and 1000 ppm, Humic Acid - corm Soaking (24hrs)+ foliar spray (45 & 90 DAP) 1,2 and 3percent, salicylic acid - corm soaking (24hrs)+ foliar spray (45 & 90 DAP)50 ppm, 100ppm and200 ppm, monocrotophos 0.2% - corm soaking (24hrs)+ foliar spray (45 & 90 DAP). Field experiments was conducted at farm of RRS, Paiyur during the period of 2016-2017 The best performed five treatments were callout from pot culture experiments I & II and further experiment was conducted at field conditions in split plot (3mX3m) with three replications. The standard cultural practices were followed as recommended by Tamil Nadu Agricultural University, Coimbatore. The observation viz., Stalk length (Cm), Inflorescences length (cm), Stalk weight(g),Total number of florets, Nematode population in root(5g), Nematode population in soil (200cc), gall index and yield were recorded.
Influence of Pruning and Integrated Nutrient Management on Custard Apple (Annona Squamosa L.)
An investigation was carried out at Fruit Research Station, Madhadi Baugh Farm, Department of Fruit science, College of Horticulture, Junagadh Agricultural University, Junagadh during April 2019 to November 2020. The experiment was laid out in Randomized Block Design with Factorial concept (FRBD) consisting three factors with three replications each. The treatment comprised with three levels of pruning and eight treatments of integrated nutrient management. The yield and yield attributes and quality parameters were significantly influenced by various level of pruning. Maximum fruit yield (2.44 t/ha), average weight of fruit (174.11 g), fruit length (6.59 cm), fruit girth (6.83 cm), maximum pulp weight (104.45 g), pulp: seed ratio (8.18), pulp: rag ratio (1.82), minimum number of seed (25.55), weight of seed (13.42 g), maximum total sugar (22.33%), reducing sugar (18.47 %), non-reducing sugar content (3.83%), ascorbic acid (21.55 mg/100g), TSS (22.31°Brix) and minimum acidity (0.25%) were noted in medium pruning at 20 cm (P3). Whereas, minimum days to flower initiation (73.41) was recorded with unpruned tree (P1). The quality parameters were also significantly influenced by organic manures are maximum total sugar (23.34%), reducing sugar (19.34%), ascorbic acid (23.02 mg/100g), TSS (22.74 °Brix) and minimum acidity (0.25%) were recorded in 100% RDN + 10 kg FYM + Azotobacter 15 ml + PSB 15 ml + Micronutrient grade-IV (0.5%) + GA3 25 ppm (F2).
Challenges, Scope, and upcoming strategies for Direct Seeding of Rice: A Global Meta-analysis
In the Indo-Gangetic Plains of South Asia, the predominant cropping system occupies 13.5 million hectares and consists of rice and wheat. Rice cultivation using the traditional puddle transplanted method requires a lot of water, capital, and energy. The structural integrity of the soil will deteriorate as a result of this system. Additionally, wheat yields are affected by aeration stress because of the formation of hard pans during the rice growing season. Growing plants on a mat-type nursery require specific expertise, and learning how to operate a transplanter puts mechanical transplanting in the background as a secondary choice. Sustainable rice production is possible with the use of direct sowing with zero or reduced tillage if the issues of weeds, nutritional deficiencies, worms, and the establishment of an aerobic variety are dealt with. Direct seeding of rice is an option for sustainable rice production. In addition, rice grown via direct seeding results in lower emissions of greenhouse gases. In this article, we examine the efficacy of directly seeding rice in soils with varying textures and a variety of agroclimatic conditions, as well as the primary challenges that this method presents.
Development and Performance Evaluation of Garlic Splitter Cum Grader
Agriculture in Pakistan is vital for the country's economy and food security, employing over 40% of the workforce and contributing significantly to the GDP. Beside major cash crops, different vegetables and fruits including garlic have a potentially high economic value. Across the farming community, garlic is usually split manually using labor force. For planting purpose, graded garlic cloves are required. Therefore, there is a need for a machine which splits and grades the garlic simultaneously. In this study, a garlic splitter cum grader was developed and its performance was evaluated. According to the results, the machine achieved 48 times more garlic splitting compared to manual labor per working day. Additionally, the machine achieved a material capacity of 6 maund/working hour. The machine was tested at different rpm, clearance, feed rate, and bulb size. In addition, two different varieties of garlic namely Chinese and Desi variety were used for the performance evaluation. The machine splits and grades the garlic cloves into three different categories (i.e., small, medium, large). Furthermore, it was observed that the manual labor only provides splitting service whereas the machine provides splitting as well as grading. It was concluded that the machine could potentially save 346 PKR/maund of split garlic.
An insight into combining ability, heterosis and gene action for false smut disease resistance and agronomic traits in rice (Oryza sativa L.)
Thirty F1s were generated using six rice genotypes with different levels of resistance to false smut based on Griffing’s full diallel fashion and evaluated at Hybrid Rice Evaluation Centre, Gudalur (Hotspot location), Tamil Nadu, India to understand the disease reaction, gene action and combining ability for seven disease related and 13 agronomic traits. Highly significant lower mean disease incidence of number of infected grains per panicle was recorded in the parents, RG170 and RG172. Eight and 11 crosses exhibited highly resistant and resistant reaction respectively. GCA variance was numerically higher than the SCA variance for 16 traits and Baker’s ratio revealed strong additive gene action for five traits. Combining ability analysis revealed marked variations of gca and sca effects for most of the studied traits in parents and crosses respectively. Parent RG 170 was inferred as the best general combiner for false smut disease resistance and agronomic traits. The crosses RG170/BPT5204 and RG162/RNR15048 expressed desirable sca effects for most of the resistance traits notably, number of infected plants, number of infected tillers and percentage of infected tillers. Use of one parents with resistance or moderate resistance would provide adequate false smut resistance combined with yield. The crosses identified from the present study viz., RG162/RG170, RG162/BPT5204, RNR15048/RG162, RG22/BPT5204, RG170/RG172 and BPT5204/ RG172 can be further utilized in pedigree breeding by scoring for false smut resistance in each generation and selection for other agronomic traits based on gene action in order to develop recombinants combining yield and false smut resistance in rice.
