A field experiment was conducted at Horticultural Research Station, Nanjanadu farm Ooty to study the effect of Integrated Nutrient Management on yield and the soil microbial populations in garlic. The experiment was carried out ina Randomized Blocks Design with 9 treatments and three replications. The plot size of 12 m2 was laid out. The experiment was conducted for three years from 2011 -13 and the pooled data was analysed. Pooled analysis was done for the three-harvest data (2011, 2012, 2013). All the organic manures like farm Yard Manure (FYM), Vermicompost (VC) and Poultry Manure (PM) and biofertilizers viz., Azospirillum and Phosphorus Solubilizing Bacteria each @ 5 kg each/ ha was applied as a basal as per the treatment. 50 % of the recommended inorganic applied as basal at the time of planting and the remaining 50 % N was applied in two equal splits during 30 and 45 days after planting. The full dose of P, K and S applied at the time of planting as per the treatment schedule. The treatments received three levels of FYM (15, 7.5,5 t -1/ha), Poultry Manure (7.5,3.75,2.5 t -1/ha) and Vermi Compost (7.5,3.75,2.5 t-1/ha). Observations are recorded on no. of leaves, Equatorial Diameter (ED), Polar Diameter (PD), Average Bulb Weight (ABW), A-grade bulbs (AGB), B grade bulbs (BGB), C grade bulbs (CGB), Marketable yield (MY) and Total yield (TY). Soil samples were collected at two stages (bulbing and at harvest) for microbial populations of total bacteria, fungi and actinomycetes. Results were compared among the treatments for total yield of garlic. Results revealed that the highest total as well as marketable yield was recorded in T 9 (75:40:40:40 Kg NPKS + 5 t FYM / ha + 2.5 t PM + 2.5 t VC/ ha) and T6 (75:40:40:40 Kg NPKS + 7.5 t FYM / ha + 3.75 t PM/ ha). Among the nine treatments significantly the maximum plant height (68.65 cm), the number of leaves (8.17), neck thickness (3.47 cm), polar diameter (40.03 mm), equatorial diameter (36.83cm), the average weight of 10 bulbs (203.34 g). B grade bulbs (51. 27 %), minimum C grade bulbs (16. 11%), marketable yield (8.52 tonnes/ ha), total yield (10.61 tonnes/ ha) was recorded in the T9 followed by T6 (9.72 tonnes /ha). The population of bacteria, fungi and actinomycetes were found to be maximum at the harvesting stage when compared to the bulbing stage under treatment T9.

This study evaluates the influence of different irrigation frequencies and different nitrogen fertigation frequencies on the growth performance of the watermelon (Citrullus lanatus) culture. Two experiments were conducted at the Paraguay farm in the Cruz municipality, Ceará, Brazil. They was randomized blocks design with six treatments and four replications. The irrigation frequency experiment consisted of the application of different irrigation frequencies. The treatments were: DM - daily irrigation in the morning with 100% daily dosage; DT - daily irrigation in the afternoon, with 100% daily dosage; DMT - twice daily irrigation, with 50% daily dosage in the morning and 50% daily dosage in the afternoon; 2D - irrigation every two days; 3D - irrigation every three days and 4D - irrigation every four days. To the experiment with different nitrogen fertigation frequencies, the treatments used were: 2F - 2 fertigations in a cycle; 4F - 4 fertigations in a cycle; 8F - 8 fertigations in a cycle; 16F - 16 fertigations in a cycle; 32F - 32 fertigations in a cycle and 64F - 64 fertigations in a cycle. We evaluated the marketable yield (PC), fruit weight (M), polar diameter (DP), equatorial diameter (DE), shell thickness (EC) and soluble solids (SS). The irrigation frequency treatments influenced all variables significantly, with twice daily irrigation (DMT, 50% in the morning and the 50% in the afternoon) promoting the highest productivity (69.79 t ha-1). The different frequencies of fertigation also significantly influenced all variables, except for the shell thickness, the highest yield (80.69 t ha-1) being obtained with treatment 64 fertigations in a cycle.

Organic And Inorganic Fertilizers

Reliance on inorganic fertilizers with less or no use of organic fertilizers has impaired the productivity of soils worldwide. Therefore, the present study was conducted to quantify the effects of integrated nutrient management on rice yield, nutrient use efficiency, soil fertility, and carbon (C) sequestration in cultivated land. The experiment was designed with seven treatments comprising of a zero input control, recommended inorganic fertilizers (RD), poultry manure (PM) (5 t ha−1) + 50% RD, PM (2.5 t ha−1) + 75% RD, vermicompost (VC) (5 t ha−1) + 50% RD, VC (2.5 t ha−1) + 75% RD, and farmers’ practice (FP) with three replications that were laid out in a randomized complete block design. The highest grain yield (6.16–6.27 t ha−1) was attained when VC and PM were applied at the rate of 2.5 t ha−1 along with 75% RD. Uptake of nutrients and their subsequent use efficiencies appeared higher and satisfactory from the combined application of organic and inorganic fertilizers. The addition of organic fertilizer significantly influenced the organic carbon, total carbon, total nitrogen, ammonium nitrogen, nitrate nitrogen, soil pH, phosphorus, potassium, sulfur, calcium, and magnesium contents in post-harvest soil, which indicated enhancement of soil fertility. The maximum value of the organic carbon stock (18.70 t ha−1), total carbon stock (20.81 t ha−1), and organic carbon sequestration (1.75 t ha−1) was observed in poultry manure at the rate of 5 t ha−1 with 50% RD. The soil bulk density decreased slightly more than that of the control, which indicated the improvement of the physical properties of soil using organic manures. Therefore, regular nourishment of soil with organic and inorganic fertilizers might help rejuvenate the soils and ensure agricultural sustainability.

For sustainable boro rice production in Bangladesh, a balanced fertilization to improve the current soil condition caused by mono-application of inorganic fertilizers and appropriate rice variety selection are very crucial. Therefore, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the boro season of December 2016 to May 2017 to evaluate the effect of integrated nutrient management on two boro rice cultivars. The varieties were BRRI dhan28 and BRRI dhan29 and eight kinds of nutrient management viz., control (no fertilizers), recommended dose of inorganic fertilizers (120-60-40 N, P2O5, K2O kg ha-1 + gypsum 60 kg ha-1 and ZnSO4 @ 10 kg ha-1), full dose of poultry manure @ 5 t ha-1, cowdung @ 10 t ha-1, poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of other inorganic fertilizers, cowdung @ 5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers, poultry manure @ 2.5 t ha-1 + 75% prilled urea and full dose of inorganic fertilizers, and cowdung @ 5 t ha-1 + 75% prilled urea and full dose of other inorganic fertilizers. The experiment was laid out in a split plot design with three replications. Result showed that, yield and yield components of boro rice were significantly influenced by variety, nutrient management and interaction of variety and nutrient management. In respect of grain yield, BRRI dhan29 produced the maximum yield (5.46 t ha-1). BRRI dhan28 showed poor performance with all characters and gave the minimum yield (4.07 t ha-1). In case of nutrient managements, the highest yield and yield component were obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers and produced the maximum grain yield (5.70 t ha-1). In the interaction of variety and integrated nutrient management, the highest grain yield (6.83 t ha-1) and straw yield (7.61 t ha-1) was obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers with BRRI dhan29 variety. So, BRRI dhan29 with 2.5 t ha-1 poultry manure + 50% prilled urea and full dose of the recommended inorganic fertilizers might be a promising practice for boro rice cultivation.

Soil applied herbicides may persist to adversely affect rotational crops as well as perturb soil microbiological functions. This experiment therefore aimed at determining the effects of soil residual activity of diuron (3,4-dichlorophenyl)-N,N-dimethylurea) on Corchorus olitorius plants and on soil microbial population. Diuron herbicide was applied to potted soils at varying times of 12, 9, 6, 3 and zero weeks before planting Corchorus olitorius. Seed germination, seedling mortality, plant growth as well as soil microbial populations were determined. Results indicated that diuron, regardless of time of application significantly reduced growth parameters of C. olitorius plants few days after emergence, and this was followed by 100% die-back in the herbicide treated pots. Results further showed a reduction in soil microbial population with diuron application, and the reduction was inversely related to time of diuron application before sowing C. olitorius. Sensitive vegetables such as C. olitorius should not be sown to succeed a short season crop in which diuron had been applied to control weeds at the usual recommended rate of 3.0 kg a.i/ha. Allowance of a fallow period following the first crop might also help the soil microbial community to recover from diuron toxicity.

A field experiment was conducted during 2007-2009 in the instructional farm of Uttar Banga Krishi Viswavidyalaya, West Bengal, India to find out the effect of integrated nutrient management on oil and protein yield of Rapeseed (Brassica campestris var. Yellow sarson). The experiment was laid out in randomized block design with 12 treatments viz., 100% Recommended Dose Fertilizer (RDF) 60:30:30 Kg ha-1 of N: P: K (T1), 100% RDF + Borax @ 10.0 Kg ha-1 (T2), FYM @ 10.0 t ha-1 (T3), Vermicompost @ 5.0 t ha-1 (T4), Neemcake @ 5.0 t ha-1 (T5), Poultry manure @ 5.0 t ha-1 (T6), T1+ FYM @ 5.0 t ha-1 (T7), T1+ Vermicompost (VC) @ 2.5 t ha-1 (T8), T1+ Neemcake (NC) @ 2.5 t ha-1 (T9), T1+ Poultry Manure (PM) @ 2.5 t ha-1 (T10), 50% RDF+ FYM @ 2.5 t ha-1 + VC @1.25 t ha-1 + NC @ 1.25 t ha-1 + PM @ 1.25 t ha-1 (T11) and Control (T12) and replicated thrice. Average results of oil and protein content and their respective yields was maximum (44.99 & 29.84% and 606.33 & 402.11 kg ha-1 respectively) in the crop fertilized with 50% RDF + FYM @ 2.5 t ha-1 + VC @1.25 t ha-1 + NC @ 1.25 t ha-1 + PM @ 1.25 t ha-1 (T11) followed by T9 i.e. application of T1+ Neemcake @ 2.5 t ha-1 (44.81 & 29.22% and 600.67 & 391.50 kg ha-1 respectively) and T8 i.e. application of T1+ Vermicompost @ 2.5 t ha-1 (44.24 & 29.01 and 585.33 & 383.67 kg ha-1 respectively). Based on pooled data T11 treatment recorded maximum seed yield of 1347.68 kg ha-1 which was statistically at par with T9 (1340.47 kg ha-1), However, treatment T1 (100 % RDF) showed highest BCR (3.85) due to low cost of cultivation.

Integrated Nutrient Management

This experiment was conducted in the farmer’s field at Khajrauta, Gadhawa-4, Dang, Nepal to evaluate the effect of integrated nutrient management on growth and yield of cauliflower as well as their residual effects on soil properties. The cauliflower variety silvercup-60 was grown under eight different treatments; T1: 50% N through RDF + 50% N through FYM; T2: 50% N through RDF + 50% N through PM; T3: 50% N through RDF + 50% N through VC, T4: 50% N through RDF + 25% N through FYM + 25% N through PM; T5: 50% N through RDF + 25% N through VC + 25% N through PM; T6: 50% N through RDF + 25% N through VC + 25% N through FYM; T7: 50% N through RDF + 25% N through  VC +25% N through FYM; T8: 50% N through RDF + 50% N  through FYM,VC and poultry manure. The experiment was laid out in RCB design with three replications. The result revealed that the  highest plant height (36.40 cm), number of leaves (15), plant spread (31.72 cm), leaf area (526.5 cm2), curd weight (207.3g) and curd yield (12.85 t/ha) were found under 50% N through RDF +50% N through VC. The root length, root diameter and root density were better under all INM treatments as compared to 100% N through RDF. INM treatments showed lesser bulk density, lesser particle density, greater infiltration rate and greater organic matter content than application of 100% N through RDF. Soil total nitrogen was increased in all INM treatments while soil available phosphorus decreases in all treatments except 100% N trough RDF and 50% N through RDF +50% N through PM. Thus, farmers are suggested to apply 50% N through VC along with 50% N through RDF to increase cauliflower yield.
