A field experiment was conducted during late Kharif (September-November) of the year 2018 at Eastern Block Farm, Tamil Nadu Agricultural University, Coimbatore to find out the effect of agronomic bio-fortification with zinc on physiological parameters, nutrient uptake, yield and economics of babycorn under irrigated condition. The field experiment was laid in randomized complete block design with three replications. The treatments comprised of T1: No zinc (control), T2: Zinc Sulphate (ZnSO4) at 25 kgha-1 as soil application, T3: ZnSO4 at 37.5 kgha-1 as soil application, T4: Foliar spray of ZnSO4 at 0.5% on 20 and 40 DAS, T5: Foliar spray of ZnSO4 at 1.0% on 20 and 40 DAS, T6: ZnSO4 at 25 kgha-1 as soil application + foliar spray at 0.5% on 20 and 40 DAS, T7 : ZnSO4 at 25 kgha-1 as soil application + foliar spray at 1.0% on 20 and 40 DAS, T8: ZnSO4 at 37.5 kgha-1 as soil application + foliar spray at 0.5% on 20 and 40 DAS, T9: ZnSO4 at 37.5 kgha-1 as soil application + foliar spray at 1.0% on 20 and 40 DAS. Babycorn hybrid G-5414 was used to experiment with a plant spacing of 45 cm x 25 cm. The results showed that the combined application of zinc sulphate @ 37.5 kgha-1 with 0.5% foliar spray at 20 and 40 DAS recorded significantly higher Crop Growth Rate (CGR) (31.07, 30.83) gcm-2day-1, Relative Growth Rate (RGR) (110.25, 31.67) mgg-1day-1 and Net Assimilation Rate (NAR) (9.65, 4.54) mgcm-2day-1 at 25-45 DAS and 45 DAS - harvest intervals respectively. NPK uptake was recorded higher in (T8) and green cob yield was recorded higher in (T9) at harvest stage. Green fodder yield and higher benefit cost ratio was obtained higher with soil application of zinc sulphate @ 37.5 kgha-1 with 0.5% foliar spray at 20 and 40 DAS.

A field experiment was conducted during spring 2020-21 at Wetland farms of Tamil Nadu Agricultural University, Coimbatore to study the effect of foliar Nanonutrients (N, Zn and Cu) application on the yield and nutrient uptake by rice at harvest. Twelve treatments with three replications were laid out in randomized complete block design. The results revealed that application of 100% NPK + Nano N at active tillering (T3) and 75% N + 100% PK + Nano N at active tillering (T4) increased the grain yield (5112 and 5063 kg ha-1) and N uptake (106.48 and 89.51 kg ha-1) of rice, respectively and was on par with 100% NPK + Nano Zn at active tillering and panicle emergence (T10). However, significantly higher Zn and Cu uptake were recorded in 100% NPK + Nano Zn at active tillering and panicle emergence (T10, 457.61 g ha-1) and 100% NPK + Nano Cu at active tillering and panicle emergence (T12, 92.36 g ha-1), respectively which was followed by 100% NPK + Nano N at active tillering (T3, 372.45 and 81.51 g ha-1) and 75% N + 100% PK + Nano N at active tillering (T4, 355.41 and 84.13 g ha-1). Thus, it can be concluded that application of foliar Nano N at active tillering along with soil application of either 100% NPK or 75% N + 100% PK can provide better results in terms of grain yield and nutrient uptake.

A field experiment was performed at Agricultural College, Bapatla, ANGRAU, Guntur during kharif season of 2020 to evaluate the efficacy of zinc nutrition on quality, yield and economics of sweetcorn. Experiment was carried out in Randomized Block Design and comprising of nine treatments with three replications. The results disclosed that application of recommended dose of fertilizers along with soil application of 10 kg ha-1 Zn EDTA + two foliar sprays of nano zinc @ 250 ppm at 20 & 40 DAS registered remarkably higher protein content (12.98%) and zinc content (34.59 ppm) in kernel which was considered to be superior over the remaining zinc management practices tried. Also, highest green cob (12,638 kg ha-1), green fodder (19,674 kg ha-1), stover yield (7,590 kg ha-1) and gross returns (₹ 1,93,360 ha-1) was recorded from the treatment with soil application of Zn EDTA @ 10 kg ha-1 + two foliar sprays of nano zinc @ 250 ppm at 20 & 40 DAS along with RDF over control. However, highest net returns (₹ 1,38,664 ha-1) and benefit cost ratio (2.74) was recorded with RDF + ZnSO4 @ 25 kg ha-1 (Soil) + Nano ZnO @ 250 ppm at 20 and 40 DAS (Foliar spray). The effectiveness of Zn EDTA compared to ZnSO4 is responsible for the higher quality parameters and yield of sweetcorn but due to its higher cost, Net returns and B;C ratio are maximum for the plots treated with ZnSO4 making it more economically viable.

A field experiment was carried out during kharif season of 2016 and 2017 at an experimental farm of MACS Agharkar Research Institute, Pune, India to study the influence of foliar application of nutrient on growth, yield, economics, soil nutritional status and nutrient uptake of soybean crop. An experiment was laid out in randomized block design (RBD) comprising of three replications and nine treatments. Recommended dose of fertilizers (RDF) was applied as basal application to all treatments. Seven treatments consisted of different doses of nutrients as foliar application at pod initiation stage. Water spray at pod initiation stage and RDF alone were treated as control. The results revealed that, growth attributes, nodulation and its weight, morpho-physiological parameters, yield and its attributes, nutritional parameters and economics significantly differed by various foliar nutrition treatments except control and RDF + water spray. RDF + Urea 2% (3098 kg ha-1) gave significantly higher seed yield over control (2704 kg ha-1) and RDF + water spray (2686 kg ha-1) but was at par with RDF + DAP 2% (3050 kg ha-1), RDF + MOP 0.5% (2992 kg ha-1) and RDF + Molybdenum 0.5% (2955 kg ha-1). The increase in seed yield with foliar application of 2% Urea along with RDF was 14.57% over control and 15.34% over RDF + water spray. Higher net returns (Rs. 49,006/- ha-1) and benefit: cost ratio (2.23:1) was obtained in treatment RDF + Urea 2% followed by RDF + DAP 2% foliar spray. Availability of N, P and K was significantly higher with treatment RDF + Urea 2% foliar spray over control and RDF + water spray. N and P uptake by soybean plants was significantly higher in treatment RDF + 2% Urea over RDF + water spray and RDF alone (control).

The field demonstrations were carried out during 2016-17 in Rabi season to know effect of zinc and boron on yield of brinjal at total 10 farmers from Bharuch district. The production of brinjal is quite low in some part of the district due poor soil fertility status and imbalance fertilizer application by farmer. There was complete absence of micronutrients application to the crop. The initial soil analysis data showed deficiency of zinc and boron in experimental soil. Thus, to compare effect and method of use of zinc and boron; soil application and foliar spray were made along with improved practices against farmer practices. The highest plant height, average fruit weight, number of fruits per plant and fruit yield of brinjal was recorded with the soil application of zinc and boron which was superior over the foliar spray and farmer’s practices. The gross return, net return and benefit cost ratio recorded was also maximum in improved practices consisting soil application of zinc and boron as compared farmer’s practices.

Npk Fertilization

Background: Nitrogen, phosphorus and potassium (NPK) are amongst the fundamental macronutrients, which are crucial for the growth and development plants. There is lack of information for the most effective method for NPK fertilization in pea cultivars grown in Pakistan. In most of the cases, NPK is applied as soil application rather than foliar spray. Methods: Experiments were conducted to find out the most effective method of NPK fertilization i.e. soil application or foliar spray on three pea cultivars (Aleena, Climax and Meteor). Experiment was arranged in a completely randomized design with 4 replicates and data was recorded at different growth stages. Result: Soil and foliar spray of NPK showed significant results for the enhancement of root and shoot development, foliage growth, relative growth rate (RGR), net assimilation rate (NAR), photosynthetic pigments, total carbohydrate contents and soluble proteins. Antioxidant activities i.e. catalases (CAT), peroxidase (POD) and yield attributes increased significantly with NPK applications. NPK foliar application showed better result only for the higher relative growth rate (RGR) and net assimilation rate (NAR). It was noted that NPK soil applications were more effective for the improvement of growth, quality and yield of pea as compared to foliar spray. Climax and Aleena cultivars were better in relation to growth, quality and yield than Meteor with soil NPK application. Changes in antioxidant activities by NPK significantly increased the defense mechanism in plants resulted improved in plant metabolism that increased the growth, yield and quality of pea. It was concluded that soil application of NPK was more effective for higher productivity of pea than foliar use.

A field experiment to assess the effect of  planting methods and sett treatments on quality, nutrient uptake and economics of bajra napier hybrid grass CO (BN) 5 was conducted during 2018-2019 at the Eastern block farm of the Department of Agronomy, Tamil Nadu Agricultural University – Coimbatore, Tamil Nadu. The experimental field was laid out in factorial randomized block design. The main plots were vertical planting (M1) and horizontal planting (M2) and sub-plots were 13 sett treatments. The results on some quality parameters viz., crude protein, crude fibre, crude fat, total ash contents (%), showed non-significant difference on planting methods, sett treatments and their interaction. Among planting methods, vertical planting had registered higher crude protein yield of 1.23 t ha-1cut-1, nitrogen uptake (151 kg ha-1cut-1), phosphorus uptake (23.4 kg ha-1cut-1) and potassium uptake (87.7 kg ha-1cut-1). Among sett treatments, water soaking for 12 hours and 24 hours incubation (S1) significantly registered higher crude protein yield (1.78 t ha-1cut-1), nitrogen uptake (186.8 kg ha-1cut-1), phosphorus uptake (31.9 kg ha-1cut-1) and potassium uptake (108.4 kg ha-1cut-1). In two planting methods, low cost of cultivation ($ 629 ha-1), higher gross return ($ 1227 ha-1), net return ($ 598 ha-1) and benefit cost ratio (1.98) were registered with vertical planting (M1). Similarly, among sett treatments, water soaking for 12 hours and 24 hours incubation (S1) recorded lower cost of cultivation ($ 563 ha-1), higher gross return ($ 1698 ha-1), net return ($ 1135 ha-1) and benefit cost ratio (3.02). With this, it can be concluded that for planting method, vertical planting (M1), and for sett treatment, water soaking for 12 hours and 24 hours incubation (S1) are the recommended practices for achieving better quality, nutrient uptake and economics from bajra napier hybrid grass.

The integrated use of chemical and organic fertilizers can help in sustainable and environmentally sound nutrient management of soils. A study was conducted in the farmer’s field of Godaghari, Rajshahi from February to May 2012 to investigate the effect of integrated nutrient management on nutrient uptake by rice cv. NERICA 10 and economization of inputs. Six treatments viz. T1 = Control, T2 = RFD for MYG + cowdung @ 5 t ha-1, T3 = RFD for HYG, T4 = RFD for HYG + cowdung @ 5 t ha-1, T5 = RFD for HYG + cowdung @ 5 t ha-1 based on IPNS, and T6 = RFD for HYG + 10% excess fertilizer of HYG were used. The experiment was laid out in a randomized complete block design with three replications. Results showed that the uptake of N, P, K, S, Ca and Mg by both grain and straw of rice were statistically significant due to use of integrated nutrient management. The highest nutrient uptake was recorded from the treatment T5 and the lowest value was obtained from control. Combined application of cowdung @ 5 t ha-1 along with recommended chemical fertilizers based on IPNS was more economic compared to other treatments because maximum benefit cost ratio was calculated from this treatment. The overall results suggest that integrated nutrient management can be used as an alternate option of chemical fertilization to achieve maximum yield, nutrient uptake and cost of return for rice cv.
