An investigation was carried out to fine tune nutrient management techniques for improving the yield of rice fallow blackgram at the Wetlands of Tamil Nadu Agricultural University, Coimbatore in a split plot design. Three fertilizer application practices viz. recommended dose of fertilizer to preceding rice crop, recommended dose of fertilizer (last split through DAP based on N equivalent) to the preceding rice crop and basal application of fertilizer to blackgram of N and P2O5 @ 12.5:25 kg ha-1 (10 days prior to harvest of rice crop) formed the main plot treatments and foliar sprays viz., control, 1% urea, 2% DAP, 1% KCl and 2% DAP + 1% KCl twice at flowering and pod filling stages of crop growth constituted the subplot treatments. The treatments were replicated thrice. The results revealed that basal application of N and P2O5 fertilizers @ 12.5:25 kg ha-1 (10 days prior to harvest of rice crop) to blackgram favoured the nutrient uptake. Similarly the NPK uptake at harvest (64.64, 6.75 and 46.51 kg ha-1) and yield (1037 kg ha-1) were significantly influenced when foliar spray of 2% DAP + 1% KCl was given at flowering and pod filling stages of crop growth. Interaction between basal application of fertilizer N and P2O5 @ 12.5:25 kg ha-1 just before the harvesting of preceding rice crop along with foliar spray of 2% DAP + 1% KCl twice at flowering and pod filling stages was significant for NPK uptake, yield attributes and yield.

The Impact

Aim: Cereal-legume cropping system has been proved to be one of the best alternatives for a productive as well as profitable farming in West Bengal. Maize is an important cereal crop which is widely grown during rainy (kharif) season throughout the State. While garden pea, a short duration winter (rabi) season vegetable, can easily fit in any existing cereal-legume cropping system. The present nutrient management strategies solely relay on NPK based chemical fertilizer application which results in the gradual deterioration in soil physical and chemical properties and stagnant crop yield. To maximize production level by spraying extracts of natural products that contain stimulants, is a strategic move to overcome the ill effects of the use of excessive doses of inorganic fertilizer. Methodology: The present field experiment was conducted in Nadia district, West Bengal during rainy and winter season of 2016-17 and 2017-18 to assess the impact of seaweed extracts on crop growth and productivity under maize-garden pea cropping sequence. There were four concentrations of Kappaphycus seaweed sap (K-sap) (5.0 and 10%); two concentrations of GA3 free K-sap (5.0 and 10%); two concentrations of Gracillaria seaweed sap (G-sap) (5.0 and 10%) and a control [Recommended dose (RD) of NPK only]. Results: Experimental results revealed that the foliar application of K-sap (10%) along with RD of NPK resulted in an impressive performance of both the crops in terms of growth (plant height, biomass, crop growth rate), yield attributes and yield, which was closely, followed G sap (10%). Throughout the growth period of garden pea, plants received recommended dose of fertilizer supplemented with K-sap at 10% concentration recorded significantly highest biomass production (56.94, 170.02 and 309.37 g m-2 respectively). Conclusion: This may be concluded that the foliar application of 10% K-sap along with RD of NPK can be recommended for maize-garden pea cropping sequence.

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.

Aim: To determine the impact of soil and foliar application of ZnSO4.7H2O at late stages of wheat as heading initiation (5% ear formation), 100% heading (complete ear formation) and heading initiation and 100% heading along with recommended dose of fertilizer on growth, yield and quality of zero till wheat. Methodology: The field experiment was conducted on zero till wheat. The treatments consisted of control (no Zn), soil application of 12.5, 25, 37.5, 50 kg ha-1 ZnSO4.7H2O and foliar application of 0.5% Zn as one spray at heading initiation (5% ear formation), one spray at 100% heading (complete ear formation) and two sprays at heading initiation and 100% heading with recommended dose of fertilizer. These treatments were evaluated in RBD with three replications. Results: Soil application of 50, 37.5 and 25 kg Zn ha-1 with two foliar sprays of 0.5% at heading initiation (5% ear formation) and 100% heading (complete ear formation) stages gave significantly higher average grain and straw yield and Zn concentration in grain than other treatments, including control. Interpretation: Enhanced application of Zn as soil and foliar application ameliorates soil Zn deficiency and increases protein content in grains, which might influence the quality and yield of zero tilled wheat.

A field experiment was conducted during the summer, 2014 at College of Agriculture, Vellayani, Kerala to evaluate the influence of irrigation levels, nitrogen stress and method of application of fertilizers on growth and yield of yard long bean. The experiment consisted of four levels of irrigation, two levels of nitrogen and two methods of application. The results indicated that daily irrigation at 10 mm depth and recommended dose of nitrogen (30 kg ha-1) recorded superior values for growth parameters viz., functional leaves per plant and leaf area index The major yield attributes like number of pods per plant and pod yield per plant and total pod yield were not influenced by levels of irrigation and nitrogen indicating that irrigation once in three days at 20 mm depth and nitrogen level of 22.5 kg ha-1 is sufficient for yard long bean. Soil and foliar application of nitrogen and potassium recorded superior growth characters, however, the yield was superior when the recommended dose of nutrients were supplied as soil application. Increasing irrigation interval to three days and imparting N stress did not result in any reduction in gross income and net income while, a higher benefit: cost ratio was noted in irrigation at wider intervals. Soil application of nutrients recorded higher gross income, net income and BCR compared to soil + foliar application.

Agronomic Biofortification

Agronomic biofortification increases the concentration of target mineral in edible portions of crops by the use of mineral fertilizers to increase dietary intake of target minerals. Among these iron and zinc deficiencies in human nutrition are noticed in countries where maize is the staple food. The objective of this study was to evaluate agronomic biofortification performance in association with Integrated Nutrient Management in maize (Zea mays .L). The study was conducted under field conditions in Chinnakandiankuppam village, Vriddhachalam Taluk, in the North-eastern region of Tamil Nadu state, India of Kharif 2020 season. Two hybrids in main plots (M1 – Non biofortified and M2 – Biofortified) were combined with six treatments in sub-plots (100 % RDF through NPK (S1), 100 % RDF through FYM (S2), 50% RDF through NPK + 50% through FYM (S3) as soil application, S1+ Zinc + Iron (S4), S2 +Zinc + Iron (S5) and S3 + Zinc + Iron (S6) as foliar application with evaluations were carried out in wet season period of the year. Application of 50 percent RDF through NPK + 50 percent RDF through FYM with Fe, Zn, foliar applications (S6) was the most efficient agronomic biofortification practice for growth attributes, yield and yield attributes, nutrient uptake, and quality parameters for the maize cropping system under the irrigated condition of the northeastern zone of Tamilnadu State, India.
