Abstract

Now-a-days, the producers are taking more interest in the nutritional harvest i.e., quality of the produce in terms of its food value rather than its quantity per hectare. Ignorance of organic manures and random use of chemical fertilizers, soil becomes vulnerable that leads to nutrient imbalance and threat to ecological sustainability. A Field experiment was conducted during the rabiseason at the College of Horticulture, Rajendranagar, Hyderabad. Palak, a nutrient-rich leafy green vegetable, is an essential crop for human consumption, providing vital vitamins, minerals, and antioxidants. To meet the increasing demand for Palak, farmers rely on fertilizers to enhance growth and productivity. Inorganic nutrients such as Nitrogen, Phosphorus, and Potassium are widely used, but their excessive application can harm the environment and human health. Biofertilizer offers a sustainable alternative to promoting plant growth while maintaining soil health. Therefore, research with the ten integrated treatments consisting of inorganic nutrients (75%, 50% and 25% NPK kg ha-1), Bio-fertilizers (Azotobacter, Phosphorus Solubilizing Bacteria (PSB), Potassium Solubilizing Bacteria (PSB), Arka Microbial Consortium (AMC) along with Arka vegetable special (micronutrient spray) @ 5 gm litre-1 was done for 3 times at 15 days interval with three replications. Results revealed that maximum growth was influenced by the application of a 50% Recommended Dose of Fertilizers (NPK kg ha-1), 50% Biofertilizers (Arka Microbial Consortium + Potassium Solubilizing Bacteria), along with Arka Vegetable Special (micronutrient spray). This study investigates the influence of inorganic nutrients and Biofertilizers on growth parameters like Leaf area, Leaf area Index, Specific leaf area, Specific leaf weight, and Leaf area duration of Palak, aiming to identify an optimal fertilization strategy that balances productivity and environmental sustainability.

Abstract

The soil texture has a significant impact on crop yield and soil fertility because it controls
root penetration, nutrient availability, and water retention—all of which are essential for plant
growth and development. This meta-analysis synthesizes data from several agroecosystems to
provide a thorough knowledge of the interactions between soil textural classes (sand, silt, and
clay proportions) and their effects on agronomic results. Sandy soils, which are distinguished
by their coarse particles, have a low capacity to hold nutrients and drain water quickly,
making frequent fertilization and irrigation necessary. On the other hand, clayey soils, which
have fine particles, are more fertile and retain more moisture, but they also present problems
including inadequate aeration and drainage, which can impede root development and cause
waterlogging. The correct ratio of sand, silt, and clay in balanced loamy soils frequently
promotes maximum productivity because of their advantageous physical and chemical
characteristics. In order to address the challenges of food security in a changing climate, the
review highlights how knowledge of the role of soil texture not only allows for targeted
management strategies catered to particular soil types, but also improves crop yields,
fertilizer efficiency, and supports sustainable agricultural practices worldwide.

Abstract

A pot culture experiment was conducted on “Influence of Phosphorus and Sulphur Application on Nutrient Content and Uptake by Sesamum in High Phosphorus soils of Telangana”. In this experiment, two high phosphorus status soils were selected consisting of 67.29 kg P 2 O 5 ha -1 and 83.46 kg P 2 O 5 ha -1 . Treatments mainly include five levels of phosphorus (P 0 -0, P 1 – 5, P 2 -10, P 3 -15 & P 4 -20 kg ha -1 of soil) and four levels of sulphur (S 0 -0, S 1 -10, S 2 -20 & S 3 -30 kg ha -1 of soil) and it was conducted factorial completely randomized design. Results indicated that a significant increase in nutrient content and uptake by sesamum crop could be achieved by combined application of 15 kg P 2 O 5 ha -1 ( 75 % RDP ) + 20 kg S ha -1 in both high available phosphorus soils. Among the various treatments tested, the highest nutrient content and uptake by sesamum crop was recorded with a combined application of 75 per cent RDP (15 kg P 2 O 5 ha -1 ) + 20 kg S ha -1 in soil 1 and 50 per cent RDP (10 kg P 2 O 5 ha -1 ) + 20 kg S ha -1 in soil 2.

Abstract

Investigation on Nutrient dynamics in foxtail millet- Melia dubia agroforestry system
under organic production system was conducted for two years (2018-19 and 2019-20) at the
University of Agricultural Sciences, Raichur, Karnataka, India. There were eleven treatments
with three replications, laid out in a completely randomized block design. In pooled data,
nitrogen, phosphorus, and potassium uptake by foxtail millet at harvest were significantly higher
in sole foxtail millet with recommended organic nutrient management practices without tree
components (45.67, 12.77 and 55.90 kg ha -1 , respectively) when compared with all the treatments
with tree association. No organic manurial treatment recorded significantly lower nitrogen,
phosphorous and potassium uptake (10.55, 4.95, and 22.18 kg ha -1 , respectively) at harvest of the
crop. While, with tree association in agroforestry system, available soil nitrogen, phosphorus and
potassium were significantly higher by application of FYM + poultry manure + panchagavya
alternated with vermiwash spray (242.80, 27.60 and 311.52 kg ha -1 , respectively) followed by
application of FYM + poultry manure + vermiwash spray (235.17, 24.93 and 288.61 kg ha -1 ,
respectively) which in turn showed significant superiority over no organic manurial treatment,
application of FYM and FYM + vermiwash spray.

Abstract

A field experiment was conducted during two consecutive kharif 2019 and 2020 on sandy loam soils of S.V. Agricultural College, Tirupati, Andhra Pradesh. The field experiment was laid out in a split-plot design with three replications. The treatments comprised of four nitrogen management practices viz., control (N1), recommended dose of fertilizer (N2), green seeker directed N application (N3) and soil test based fertilizer application (N4) assigned to main plots and nine weed management practices viz., unweeded check (W1), hand weeding twice at 15 and 30 DAS (W2), pre emergence application of atrazine 1.0 kg ha-1 fb post emergence application of topramezone 30 g ha-1 (W3), pre emergence application of atrazine 1.0 kg ha-1 fb post emergence application of tembotrione 120 g ha-1 (W4), application of parthenium water extract 15 l ha-1 twice at 15 and 30 DAS (W5), application of sunflower water extract 15 l ha-1 twice at 15 and 30 DAS (W6), pre emergence application of atrazine 1.0 kg ha-1 fb post emergence application of parthenium water extract 15 l ha-1 (W7), pre emergence application of atrazine 1.0 kg ha-1 fb post emergence application of sunflower water extract 15 l ha-1 (W8) and brown manuring (W9) allotted to subplots. Growth parameters of maize, yield attributes, and yield were higher with green seeker-directed N application (N3). Control (N1¬) recorded significantly lower values during both the years of study and in the pooled mean. With regard to weed management practices, significantly higher values were produced with hand weeding twice at 15 and 30 DAS (W2), which was however, in parity with pre-emergence application of atrazine 1.0 kg ha-1 fb post-emergence application of topramezone 30 g ha-1 (W3) and pre emergence application of atrazine 1.0 kg ha-1 fb post-emergence application of tembotrione 120 g ha-1 (W4). Lower values of growth parameters were recorded with an unweeded check (W1). Significant interaction between nitrogen and weed management practices was observed with dry matter production, cob length, kernel weight cob-1, kernel yield and stover yield. Higher and lower values were recorded with green seeker-directed N application along with hand weeding twice at 15 and 30 DAS (N3W2) and control coupled with an unweeded check (N1W1) respectively during both the years of study and in pooled mean.

Abstract

Main Forage Research Station, ICAR Unit 9, Anand Agricultural University located in the middle agroclimatic zone of Gujarat India, has different Agroclimatic zone with a different agricultural pattern. Most of the farmers are doing agriculture as a first enterprise and dairy as a second one. The demand for fodder is higher in the different zone of Gujarat state. To improve cultural practices and reduced the shortfall of fodder with highly nutritive fodder these studies were carried out to evaluate the effect of the level of nitrogen on different marvel grass varieties in middle Gujarat. Continuous three years of experimentation on marvel grass, results revealed that marvel grass varieties did not show significant effects on growth, yield attributes, and yield as well as quality parameters. A perusal of experiment data revealed that application of 60 kg N/ha (30 kg N/ha at the time of transplanting or immediately after cutting and 30 kg N/ha at 30 DAS/ 30 Days after each cutting) noted higher growth parameters (height and several tillers per meter row length) also reported higher total green fodder yield and quality of marvel grass as well as higher net return and benefit-cost ratio.
