Soil Quality Assessment as Influenced by Direct Effect of Nutrient Management Practices in Pearlmillet (Pennisetum glaucum L.) -Mungbean (Vigna radiata L.) System
A field experiment was conducted during the spring–rainy (kharif) season of 2019 on a pearlmillet–mungbean cropping system at the Department of Agronomy, Anand Agricultural University's college agronomy farm Gujarat, India. The objectives of this study were to investigate the direct effect of organic sources, inorganic fertilizers and liquid biofertilizer to applied pearlmillet on soil physical, chemical and biological properties after harvest of pearlmillet crop in a pearlmillet–mungbean cropping system. The experiment with ten treatments was laid out in a completely randomized block design with four replications. The direct effects of different nutrient management practices applied to pearlmillet were significant (P<0.05) on the water holding capacity of the soil, electrical conductivity, organic carbon, cation exchange capacity, available NPK & sulphur. The direct effect of nutrient management practices on soil pH and bulk density found non-significant. The soil microbiological properties were significantly improved, including the population of total bacterial, Azotobacter, phosphate solubilizing bacteria (PSB), microbial biomass carbon and dehydrogenase activity of soil after harvest pearlmillet crop. Application of 100 % RDF + 15 t FYM ha-1 + Bio NP consortia (T5) significantly improved the soil available nutrients and cation exchange capacity.
Effect of Phospho-enriched compost and fertility levels on different fraction of phosphorus in maize crop
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
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.)
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
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.
