Effect of Phospho-enriched compost and fertility levels on different fraction of phosphorus in maize crop

Paper ID- AMA-17-01-2022-11019

Soil phosphorus forms have been practically defined as chemically fractionated pools. A knowledge of the phosphorus fraction in soil and factor affecting them will lead to better soil management. The aim of study is to investigate study the effect of phospho enriched compost and fertility levels on different fraction of phosphorus. The experiment was undertaken during Kharif 2018 and 2019 at Instructional Farm (Agronomy), Rajasthan College of Agriculture, Udaipur (Rajasthan). The treatments comprised of four levels of phospho enriched compost (PEC) i.e. control, PEC @ 2.0, 4.0 and 6.0 t ha-1 and four levels of fertility i.e. control, 50% RDF + foliar spray of Zn 0.5%, 75% RDF + foliar spray of Zn 0.5% and 100% RDF + foliar spray of Zn 0.5% kg ha-1. The extractable-P, total-P, organic-P, saloid bound-P, aluminium bound-P, iron bound-P, calcium bound-P, reductant soluble-P, iron + aluminium bound-P, carbonate bound-P, occluded-P in soil at harvest stage of crop ware increased significantly with increasing levels of phospho enriched compost during both the years and in pooled analysis. The chemical pools of phosphorus viz. extractable-P, total-P, organic-P, saloid bound-P, aluminium bound-P, iron bound-P, calcium bound-P, reductant soluble-P, iron + aluminium bound-P, carbonate bound-P, occluded-P in soil increased significantly with application of fertility levels with foliar spray of zinc.

Design and experiment of 2F-40 type suspended organic fertilizer deep applicator

Paper ID- AMA-15-01-2022-11018

In view of the problems of low fertilization efficiency of conventional fertilizer applicators, easy clogging of organic fertilizer, and difficulty in mixing organic fertilizer and chemical fertilizer, a hanging deep watermelon organic fertilizer applicator is designed, which realizes a single operation process to complete the opening of fertilizer ditch and chemical fertilizer. The mechanized duplex operation of organic fertilizer mixed deep application and trench soil backfilling. Through the combined design of the crushing knife group and the auger fertilizer discharger, the pulverization and uniform transportation of organic fertilizers are realized the mechanized mixing and deep application of organic fertilizers/chemical fertilizers are realized, and precise control can be performed according to the nutrient requirements of watermelon. The ratio of organic and chemical fertilizers. The performance test shows that the working parts of the watermelon organic fertilizer deep applicator run stably. The field test shows that the fertilizer particles are evenly distributed, among which the distribution stability coefficient of organic fertilizer is ≥91.65%, the stability coefficient of chemical fertilizer distribution is ≥93.28%, and the distribution of mixed fertilizer The stability coefficient is ≥ 93. 70%, which meets the production requirements of watermelon.

Mechanized weed management in Chickpea (Cicer arietinum L.)

Paper ID- AMA-15-01-2022-11017

A study was carried out during Rabi (winter) season of 2017-18 and 2018-19 at Research Farm, CCSHAU Regional Research Station, Bawal, India to find out cost effective weed management technique through mechanized interculture in chickpea with modifications in row spacing. The experiment consisted to nine treatments and laid out in randomized block design replicated thrice. The crop was infested with Chenopodium album, Chenopodium murale, Anagallis arvensis, Phalaris minor etc. Two mechanized interculture with tractor drawn cultivator 30 and 60 DAS under 60 cm row sopacing was found cost effective and more profitable seed yield of 1.65t/ha, and 26 % lesser cost of cultivation; 25 % higher net returns; and B:C ratio of 2.14 compared to the recommended manual interculture with Kasola at 25-30 and 45-50 DAS under 45cm row spacing over two years (2017-18 and 2018 -19). WCE of two mechanized interculture with tractor drawn cultivator or power weeder ranged from 59-63 % in comparison with 70 % observed under recommended two interculture with Kasola. Uncontrolled weeds throughout the crop season caused yield loss of 53 % over study period.

Effect of aggressiveness and varietal screening in sesame against stem and Root Rot Pathogen

Paper ID- AMA-15-01-2022-11016

Sesame is important oilseed crop growing under light and drained soil for the oil and medicinal purpose. Stem and root rot caused maximum losses under sesame growing area and management is too difficult because of soil borne nature of the pathogen. Ten isolates collected from major sesame growing area of Rajasthan in which, all the isolates were significantly pathogenic on sesame tested on highly susceptible variety VRI-1 and produced typical symptoms. Among all the isolates, MPjd1 showed higher per cent disease incidence (56.00%) with minimum germination per cent (86.67%) of sesame seed tested against stem and root rot disease followed by MPjd2 (49.23%) disease incidence. Initial symptoms occurred within 26 days after sowing and found maximum pre emergence mortality with MPjd1 isolate. Twenty five entries of sesame were screened under field condition against stem and root rot and found that the none of variety or germplasm was recorded free from disease and categorized as immune or resistant. Only seven varieties namely RT-54, RT- 103, RT- 125, RT- 127, RT-351, RT- 346 and TKG- 306 were found moderately resistant.

Impact of ICAR-participatory seed production on the income of the small-holders farmers’ in Imphal West district of Manipur, India.

Paper ID- AMA-14-01-2022-11015

This study was conducted in Imphal West district of Manipur so as to assess the impact of the ICAR-Participatory Seed Production (PSP) on the income of the small-holder farmers who have been producing quality seeds of rice. Altogether 50 farmers who cultivates ICAR most popular rice varieties (RC-Maniphou-12; RC-maniphou-13 and RC-maniphou-7) were selected for the study using purposive sampling technique. The study incorporates both the participating farmers and the implementing agency (ICAR) so as to take the complete information for analysis of the data. The study reveals that the participating farmers perceived the knowledge of the quality seed production and it is also found that the implementing agency has imparted the complete package and practices of seed production along with the necessary seed certification modalities. With the use of the ICAR varieties (RC-Maniphou-7; RC-Maniphou-12 and RC-Maniphou-13), it is also found that the yield of the rice increases by 37.5 %; 28.5 % and 62.5 % respectively as compared to the yield of the local cultivars and conventional rice production system. The results also show that 22% of the participating farmers have cultivated and produced quality rice seeds in both the pre-kharif and kharif season. 82% of the farmers’ reveals that their incomes have been increased almost by doubled whereas 18% have realized more than 50%. It is also found that almost all the seed producers can reduced their cost of cultivation upto 9 %. Lack of sufficient revolving fund for timely payment for buyback of seeds from farmers, high transportation charges and lack of manpower and storage facilities are the major constraints face by the implementing agencies whereas delayed payment for the seed, outbreak of major pests & diseases and natural calamities are the major problems encountered by the participating rice seed growers of the district.
