Soil Fertility Status

A field experiment was conducted to study the integrated use of organic and inorganic fertilizers on the soil fertility status of Entic Haplustart in maize at Malayalathanpatti village, situated at Madurai district during Kharif season of 2008-2009. The experiment was conducted in Randomized Block Design with three replications in Annaiyur soil series (Entic Haplustert). The results revealed that highest grain yield of 4402 kg ha-1 was recorded in treatment that received vermicompost @ 5t ha-1 with 75 percent Recommended dose of fertilizer (RDF) and it was found to be superior to over treatments. Application of vermicompost @ 5t ha-1+75 percent RDF recorded the highest calcium and magnesium content in pot harvest soil sample (0.139 and 0.281%). And also increased the crude protein (16.67 %) and starch (81.34 %) content in maize crop and it was followed by the treatment which received sewage sludge 2t ha-1 with 75 percent RDF (Recommended dose of fertilizers) and green leaf manure @12.5t ha-1whereas the lowest value was recorded in control plot respectively. The vermicompost along with inorganic fertilizers were efficiently used by maize crop for their growth and development and also maintainined soil fertility and increased yield of the crop.

Soil Fertility Status

A field experiment was conducted to evaluate the effect of integrated nutrient management modules on garlic yield, nutrient uptake, and pungency during 2011-12 and 2012-13. The experiment consisted of nine treatments that were performed in randomized block design with three replications. Integration of inorganic fertilizers, farm yard manure (FYM) and vermicompost (VC) or poultry manure (PM) or integration of inorganic fertilizers with FYM, VC and PM increased garlic yield by 6.5-7.9 per cent compared to inorganic fertilizers alone and 9.9-11.2 per cent compared to integrated use of single source of organic manure, biofertilizers, and inorganic fertilizers. Pyruvic acid content was higher in the plots received integrated use of inorganic fertilizers, organic manures, and biofertilizers increased soil organic carbon, and maintained soil fertility status compared to pre-planting soil test values. INM treatments had higher levels of nutrient uptake compared to the treatments received inorganic fertilizers alone. This result indicate that the farmers could save 25 per cent inorganic fertilizers and organic manures by integrating inorganic fertilizers, FYM with VC or PM, or by integrating inorganic fertilizers, FYM, VC, and PM.

The experiment was carried out during kharif season of 2013. The experiment was conducted in randomized block design with three replications using cv. HG - 365, with eleven treatments. The combination of FYM and vermicompost with two kinds of bio-fertilizers (Azotobacter and PSB) and reduced doses of chemical fertilizers were tested in comparison to recommended dose fertilizer. The yield components viz., number of clusters plant-1, number of pods in a cluster, length and diameter of pod differed significantly due to the different INM treatment. The treatment 75% of recommended dose of inorganic fertilizers and 25% RDF through vermicompost along with biofertilizers (Rhizobium at 25 g kg-1 seed + PSB at 5 kg ha- 1) recorded significantly highest pod yield (159.58 g plant-1). Hence, it was concluded that, for getting optimum growth, and higher pod yield the crop should be supplied with the 75% of recommended dose of inorganic fertilizers and 25% RDF through vermicompost alongwith biofertilizers (Rhizobium at 25 g kg-1 seed + PSB at 5 kg ha-1).

Field experiments were conducted at experimental farm, Faculty of Agriculture, Annamalai University, Chidambaram during July to September (2008) and January to March (2009) in two seasons to study the effect of foliar spray of Panchagavya on the growth and yield of Baby corn cv. COBC 1. The experiments were laid out in Randomized Block Design with fourteen treatments and replicated thrice. The treatments included foliar spray and inorganic nutrient application at various stages of baby corn. The results revealed that application of 100% recommended dose of fertilizers (RDF) [N150: P60 (P2O5): K40 (K2O)] and 4 sprays (15, 25, 35 and 45 DAS) of 3 % Panchagavya recorded the highest growth attributes and yield of fresh Baby corn and this was followed by application of recommended dose of fertilizers (100 %) along with 3 sprays (15, 25 and 35 DAS) of 3 % panchagavya during both the seasons. The least growth and yield parameter were recorded in 3 sprays of 4 % Panchagavya without use of inorganic fertilizers. The increase in growth and yield of baby corn was mainly attributed by greater availability of nutrients through soil application (100 % RDF) and foliar spray of panchagavya at various stages of crop growth.

The Impact

A field experiment was conducted during 2018 and 2019 at Tamil Nadu Agricultural University, Agriculture College and Research Institute, Coimbatore to study the impact of weed management practices on yield attributes, economics and phytotoxicity of kharif maize. Ten treatments were tested in randomized block design with three replications viz., pre emergence (PE) atrazine at 0.5 kg a.i. ha-1 fb hand weeding (HW) at 20 DAS, PE atrazine at 0.5 kg a.i. ha-1 fb power weeder (PW) at 20 DAS, PE atrazine at 0.5 kg a.i. ha-1 + pendimethalin at 1 kg a.i. ha-1 (Tank mix), PE atrazine at 0.5 kg a.i. ha-1 + pendimethalin at 1 kg a.i. ha-1 fb HW at 20 DAS, early post emergence (EPoE) topramezone at 25.2 g a.i. ha-1, PE atrazine at 0.5 kg a.i. ha-1 fb EPoE topramezone at 25.2 g a.i. ha-1, EPoE tembotrione at 122 g a.i. ha-1, PE atrazine 0.5 kg a.i. ha-1 fb EPoE tembotrione 122 g a.i. ha-1, hand weeding twice at 20 and 45 DAS and control (weedy check). Among the different weed management practices significantly higher yield attributes viz., cob length, cob girth, weight of cob, No. of grain rows cob-1, No. of grains cob-1, grain yield cob-1 was found with hand weeding twice at 20 and 45 DAS and it was at par with atrazine at 0.5 kg a.i. ha-1 as PE  fb topramezone at 25.2 g a.i. ha-1 as EPoE and atrazine at 0.5 kg a.i. ha-1 as PE + tembotrione at 122 g a.i. ha-1 as EPoE. Maximum net return and B:C ratio were recorded under atrazine at 0.5 kg a.i. ha-1 as PE fb topramezone at 25.2 g a.i. ha-1 as EPoE followed by atrazine at 0.5 kg a.i. ha-1 as PE + tembotrione at 122 g a.i. ha-1 as EPoE. However, among the different herbicidal treatments used, all the herbicidal treatments were found to be safe to the maize crop without any caused phototoxic effect on maize during both the years of experimentation. Now-a-days, increased labour scarcity and costs are encouraging farmers to adopt labour and cost- saving options by using chemical method.

Effect Of Age

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to December 2014 with a view to finding out the effect of age of seedlings at staggered transplanting and nutrient management on growth and yield of aromatic fine grained rice (cv. BRRI dhan38). The experiment consisted of three ages of seedlings (30, 45 and 60 day-old) at staggered transplanting and six nutrient managements viz. control (no nutrients), recommended dose of inorganic fertilizers, 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 and 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. The experiment was laid out in a randomized complete block design with three replications. The effect of age of seedlings at staggered transplanting, nutrient management and their interactions were significant on crop characters, yield components and yield of aromatic fine rice. The tallest plant was recorded due to transplanting 30- day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. The highest leaf area index (6.55), number of total tillers hill-1 (12.56), number of effective tillers hill-1 (8.54), panicle length (24.07cm) and number of grains panicle-1 (141.3) were recorded in 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 while the lowest values were recorded in 60-day old seedling with control. In case of sterile spikelets panicle-1, 60-day old seedlings with control treatment showed the highest value (30.94). The highest grain (3.85 t ha-1) and straw (5.29 t ha-1) yields were obtained in 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. Therefore, 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 appeared as the promising technique for appreciable growth and grain yield of aromatic fine grained rice (cv. BRRI dhan38).SAARC J. Agri., 16(1): 49-59 (2018)

Effect Of Age

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to December 2014 with a view to finding out the effect of age of seedlings at staggered planting and nutrient management on growth of aromatic fine rice (cv. BRRI dhan38). The experiment comprised three ages of seedlings viz., 30, 45 and 60-day old and six treatment of nutrient managements viz. control (no manures and fertilizers),  recommended dose of inorganic fertilizers, 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1,  50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 and 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. The experiment was laid out in a randomized complete block design with three replications. The effect of age of seedlings and nutrient management and their interaction were significant on crop growth characters of aromatic fine rice. The result revealed that the highest plant height, total tiller hill-1, total dry matter production hill-1 and CGR were found when 30-day old seedlings were transplanted. Among the nutrient managements the highest growth parameters was obtain in 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 due to the continuous supply of nutrients by the combination of organic and inorganic fertilizer which led to better growth in plants. In 30-day old seedlings with 75% inorganic fertilizer + poultry manure @ 2.5 t ha-1 treatment performed best in case of all growth parameters, while the lowest one was observed in 60-day old seedlings with control. Therefore, 30-day old seedlings with 75% inorganic fertilizer + poultry manure @ 2.5 t ha-1 treatment might be a promising practice in aromatic fine rice cultivation in terms of growth performance.

Soil Fertility Status

A field experiment was conducted in popular carrot cultivar Nepa Dream using randomized complete block design (RCBD) with four replications for evaluating the effects of ten different treatments of soil conditioner in combination with organic and inorganic fertilizers on root growth and soil productivity. Soil samples from each microplot were also analyzed for soil texture, pH, organic matter, total nitrogen, available nitrogen, total phosphorus and total potassium before sowing and after harvest. Effects on soil was not significant in the single season experiment but effects of the treatments on the carrot root growth and production was significant. For higher root yield and biological yield, treatments Soil Conditioner +Micronutrient (Double Dose)+1/2 Recommended Dose of Fertilizer +1/2 Farm Yard Manure (T10) followed by Soil Conditioner +Micronutrient (Normal)+1/2Recommended Dose of Fertilizer +1/2 Farm Yard Manure (T7), and Recommended Dose of Fertilizer Full (T2) were found better whereas treatment T10 was found closer to T2 and Soil Conditioner +Micronutrient  (Double Dose)+Farm Yard Manure Full (T9) which showed higher mean performances for root diameter, cortex diameter and root length of carrot. In contrast, total soluble sugar as % brix was found less in the treatments involving one or more combinations of conditioner whereas highest for Farm Yard Manure and Recommended Dose of Fertilizer treatments either alone or in combination.  Thus, use of normal dose of GMT™ soil conditioner along with ½ Recommended Dose of Fertilizer and ½ Farm Yard Manure (T7) can be used as an alternative to T2 for higher carrot production which also can reduce the use of commercial inorganic fertilizers for improving soil fertility status. For organic carrot production at low cost, T9 can also be used as an alternative to other combinations of chemical fertilizers.
