Biochar is considered as a possible and potential tool for soil fertility improvement, climate change mitigation and long term sink for atmospheric carbon dioxide. Soil application of biochar enhances the soil properties indirectly. A field experiment was conducted to evaluate the influence of organic manures viz., Farm Yard Manure (FYM), Vermicompost, Biochar, Biochar composite on soil properties, growth and yield of bhendi, Abelmoschus esculentus in Somayyanur soil series of Madurai district, Tamil Nadu. The experiment was laid out in randomized block design (RBD) with eleven treatments and three replications during the summer season (March – June) 2021 with the inclusion of inorganic fertilizers based on soil test crop response (STCR) based recommendation. Application of biochar composite (5 t ha-1) along with STCR based NPK (75% STCR) increased the total carbon content in soil by 0.538 %. This, in turn, increased the available nitrogen status to 295 and 244 Kg ha-1 at 40 and 70 DAS, respectively. Similarly, the available phosphorous (22.4, 19.3 Kg ha-1) and potassium (344.70, 323.70 Kg ha-1) status also showed a considerable increase with the same treatment. The yield attributes of bhendi viz., fruit length, girth, weight, dry matter production and yield recorded maximum values of 15.23 cm, 6.93 cm, 21.56 g, 11.9 t ha-1 and 25.20 t ha-1 with the combined application of biochar composite and NPK. The findings revealed that 25 % STCR based NPK could be reduced with the application of 5 t ha-1 of biochar composite, which is economically an option besides promoting soil health.

Background: Investigations were carried out during Rabi, 2016 and Summer, 2017 at farmer’s field in Kodukkanpalayam village of Cuddalore District, Tamil Nadu to evaluate the direct effects of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), crop residues, farmyard manure with 50% inorganic sources, with and without Rhizobia on various traits of groundnut. There were twelve treatments in randomized block design (RBD) with three replications. Results revealed that the growth and yield components of groundnut viz., plant height, DMP and LAI at flowering stage, number of pods per plant, hundred kernel weight, pod yield and kernel yield were greatly influenced by the treatments. Methods: Combination of Pressmud @ 12.5 t ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T7) recorded the highest and followed by the application of distillery spentwash @ 100 m3 ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T8). Similar trend of results was recorded in summer, 2017 also. This might be due to the increase in the availability of nutrients, which increased the growth and yield attributes of groundnut in both the seasons. Also, use of agro industrial wastes and biofertilizers in any cropping sequence minimize the cost of inorganic fertilizers, thereby act as a boom to farmers by making the waste into wealth and maintain the soil health and fertility. Result: The study revealed the scope of utilization of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), organic sources (crop residues and FYM) and biofertilizer (Rhizobia) in Agriculture.

Background: Black gram (Vigna mungo. L) is one of the most cultivated legume pulse crop with high nutritive value and Malabar neem (Melia dubia) is an emerging industrial agroforestry tree in Southern India. To maximize the land utilization with a field experiment was conducted at Western zone of Tamil Nadu to investigate the performance of black gram varieties under different spatial arrangements of Melia dubia plantations. Methods: An agroforestry trial was laid out in randomized block design (RBD) with eight treatments and three replications during kharif and rabi (2019-20) season. Black gram crop varieties (V1 - CO6 and V2 - VBN 6) were intercropped with M. dubia (1.5 year old plantation) with three different spacing of S1 (3 x 1.5 m), S2 (3 x 3 m) and S3 (4 x 4 m) while S0 as open field (Sole crop of black gram) for both the season. Result: The results of pooled analysis of two season shown that, treatment S0V2 recorded plant height (49.96 cm), number of branches (3.76), number of leaves (259.75), number of flowers (53.44), number of pods (22.85), seed yield per plant (5.38 g) and seed yield per hectare (0.82 tonnes) in open condition. Similarly in intercropping the growth and yield attributes of black gram were minimum performance recorded in CO 6 at closer spacing (3 x 1.5 m). In tree growth maximum pooled height increment (1.57 m) was observed in closer spacing (3 x 1.5 m) and maximum diameter recorded in wider spacing of both varieties. Hence wider spacing of S3 (4 x 4 m) can be suggested for intercropping under M. dubia plantations upto 4 years.

An experiment was conducted at Research and Demonstration Farm of Agricultural Science Department, Federal College of Education, Pankshin located in the Northern Guinea Savanna Agro-ecological Zone of Nigeria to investigate defoliation effects on morphological characters and yield attributes of okra (Abelmoschus esculentus) carried out during 2015 and 2016 dry season. The experiment comprised five levels of defoliation viz: 0% (control), 30%, 60%, 90%, and 100%. The experiment was laid out in identical Randomized Complete Block Design (RCBD) with six replications. Results revealed that defoliation had significant effect on the studied crop characters and yield. Most of the parameters like plant height, stem girth; number of leaves, leaf area, and yield parameters decreases which are a function of increasing defoliation levels intensity. Defoliation at 0% and 30% were tolerable for okra plant growth and development, while at 90% and 100% was detrimental to plant growth and yield. Hence, defoliation at 30% is recommended to meet farmers’ pod and leaf requirement.

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.

To study the effects of cover methods and nitrogen (N) levels on the growth and yield components of tomato Cv. Pear F1, field experiments with a 4x3 factorial design were conducted in the 2019 spring and winter seasons using a randomized complete block design with three replications. The cover methods included four treatments: bare soil (BS), black plastic mulch (BPM), transparent polypropylene row cover (RC), and a combination of BPM and RC (BPMRC) with the RC removed approximately 30 days after transplanting. Nitrogen (N) was applied at three levels (150, 180, and 210 kg N ha-1). Using BPM and RC generally led to an increased air temperature, air humidity, soil moisture, and soil temperature compared to the BS treatment. Higher N rates (180 and 210 kg N ha-1) did not result  in different tomato fruit sizes and fruit weights but positively increased fruit yield and quality (Brix values and fruit dry weight) as compared to the 150 kg N ha-1 addition. The cover methods positively affected the yield components and fruit yield of tomato as well as the fruit characteristics compared to the BS treatment. Using cover materials (BPM and RC) combined with a higher N application significantly increased the yield attributes and fruit yield. The highest fruit yield was achieved under the mulching treatment by black plastic (BPM treatment) combined with a 210 kg N ha-1 application, resulting in 50.90 tons ha-1 in the spring and 58.27 tons ha-1 in the winter.

Abstract. Modern agricultural systems rely on inorganic nitrogen (N) fertilization to enhance crop yields, but its overuse may negatively affect soil properties. Our objective was to investigate the effect of long-term N fertilization on key soil properties under continuous corn [Zea mays L.] (CCC) and both the corn (Cs) and soybean [Glycine max L. Merr.] (Sc) phases of a corn-soybean rotation. Research plots were established in 1981 with treatments arranged as a split-plot design in a randomized complete block design with three replications. The main plot was crop rotation (CCC, Cs, and Sc), and the subplots were N fertilizer rates of 0 kg N ha−1 (N0, controls), and 202 kg N ha−1, and 269 kg N ha−1 (N202, and N269, respectively). After 36 years and within the CCC, the yearly addition of N269 compared to unfertilized controls significantly increased cation exchange capacity (CEC, 65 % higher under N269) and acidified the top 15 cm of the soil (pH 4.8 vs. pH 6.5). Soil organic matter (SOM) and total carbon stocks (TCs) were not affected by treatments, yet water aggregate stability (WAS) decreased by 6.7 % within the soybean phase of the CS rotation compared to CCC. Soil bulk density (BD) decreased with increased fertilization by 5 % from N0 to N269. Although ammonium (NH4+) did not differ by treatments, nitrate (NO3−) increased eight-fold with N269 compared to N0, implying increased nitrification. Soils of unfertilized controls under CCC have over twice the available phosphorus level (P) and 40 % more potassium (K) than the soils of fertilized plots (N202 and N269). On average, corn yields increased 60 % with N fertilization compared to N0. Likewise, under N0, rotated corn yielded 45 % more than CCC; the addition of N (N202 and N269) decreased the crop rotation benefit to 17 %. Our results indicated that due to the increased level of corn residues returned to the soil in fertilized systems, long-term N fertilization improved WAS and BD, yet not SOM, at the cost of significant soil acidification and greater risk of N leaching and increased nitrous oxide emissions.

A pot experiment was carried out in the nethouse of Soil Science Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2014-2015 through 2015-2016. The design of the experiment was factorial randomized completely block design with 4 replications. The objectives of the study were to evaluate the potential of Arbuscular mycorrhization (AM) on the germination, yield and yield attributes of lentil treated with different concentration of sodium chloride (NaCl). Five NaCl treatments (0, 1, 2, 3 and 4%) possessed NaCl level as the first factor that were treated with soils before sowing of lentil seeds overriding or pivotal pulse crop in Bangladesh. The second factor consists of mycorrhizal and non-mycorrhizal treatments. Mycorrhizal plants showed better performance in terms of germination %, yield and yield contributing characters than non-mycorrhizal plants. With increasing NaCl concentration germination %, yield and yield contributing characters in the rhizosphere soil, decreased significantly (p<0.01). Interaction effects of mycorrhizal inoculation and NaCl on germination %, growth and yield of lentil were appeared to be statistically non-significant. The highest germination (96.25% in 2014-2015 and 92.50% in 2015-2016), seed yield (6.45 g pot-1 in 2014-2015 and 5.89 g pot-1 in 2015-2016), and stover yield (9.55 g pot-1 in 2014-2015 and 8.58 g pot-1 in 2015-2016) was found in NaCl 0% + AM treatment. The lowest germination %, seed yield and stover yield was found in NaCl 4% treatment. Mycorrhizal inoculation increased seed yield on an average by 31.85% during 2014-2015 and 63.71% during 2015-2016, and increased stover yield on an average by 48.56% during 2014-2015 and 63.55% during 2015-2016 over non-mycorrhizal inoculation. Therefore, it can be concluded that mycorrhizal inoculation increases germination %, growth and yield of lentil over non-mycorrhizal inoculation. The Agriculturists 2017; 15(1) 156-169
