On-Farm trail was conducted in Longleng district of Nagaland during the kharif season of 2014-15 and 2015-16 to find out the most suitable nutrient management practices viz. recommended doses of fertilizers (RDF) 80:60:40 kg NPK/ha, locally available weed biomass (Eupatorium @ 10 t/ha) and farmers practices at farmers field of Krishi Vigyan Kendra, Longleng, Nagaland. The experiment was laid out in Completely Randomized Block Design. Result revealed that growth and yield parameters were recorded maximum under RDF and followed by Eupatorium @ 10 t/ha compared to farmers practice. The maximum grain yield (3590 kg/ha) was with RDF closely followed by weed biomass @10t/ha (3270 kg/ha) over the farmer's practices (2730 kg/ha), respectively. Grain yield was increased by 31.5 % in RDF and 11.8 % in Eupatorium @ 10 t/ha compared to the farmer's practices. Similarly, production efficiency was recorded the highest with RDF (28 kg/ha/day) followed by Eupatorium @ 10 t/ha (25.5 kg/ha/day) and farmers practice (21.3 kg/ha/day). With respect to economics, the maximum net returns and benefit: cost ratio (B: C ratio) were recorded with RDF (Rs.18850/ha and 1.91) as compared to other treatments. Economic efficiency was also noted highest under RDF (Rs.147.27/ha/day) followed by Eupatorium @10 t/ha (Rs.128.36/ha/day). Hence, it may be concluded that the farmer’s practices can be replaced with the adoption of RDF or locally available weed biomass (Eupatorium) as a source of nutrition for achieving the higher productivity and profitability of the lowland rice under the mid-hill altitude condition of Nagaland

Rice is an important cultivated food crop which feeds more than half of the world's population. Even though the area under rice cultivation is large, the productivity is low due to various interaction factors. The imbalance in usage of fertilizers is one of the main factors responsible for the low productivity and also the continuous use of inorganic fertilizers resulted in declining of soil fertility. An integrated nutrient management practices may be necessary to maintain the sustainability in crop production. Field experiment was conducted at wetland farm of Tamil Nadu Agricultural University, Coimbatore during kharif season to study the effect of integrated nutrient management practices on growth, physiological, nutrient uptake, root characters and yield parameters of transplanted lowland rice. The experiment was laid out in randomized block design with three replications and nine treatments. Rice CO(R) 48 was used as a test variety. Dhaincha, vermicompost, farmyard manure were incorporated before transplanting of rice as per treatment schedule. The results revealed growth parameters (Plant height and number of tillers hill-1), physiological parameters (leaf area index and crop growth rate),  nutrient uptake (N, P and K uptake), root characters (root length, root volume and root dry weight) and yield parameters (Number of productive tillers m-2 and Dry Matter Production) were significantly influenced with application of 100 % NPK through inorganic fertilizers + 6.25 t dhaincha which was comparable with 100 per cent NPK through inorganic fertilizers + 5 t vermicompost and 100 per cent NPK through inorganic fertilizers + 12.5t farmyard manure. This was followed by 100 per cent N through dhaincha + balance P & K through inorganic fertilizers.

The Impact

The experiment was conducted in a greenhouse during 2017 and 2018 growing seasons to evaluate the impact of the shading and various nutrition programs on mitigating heat stress, reducing the use of chemical minerals, improving the reproductive growth and yield of tomato plant. Split-plot within Randomized Complete Block Design (RCBD) with three replications was conducted in this study. Shading factor was allocated in the main plots and the nutrition programs distributed randomly in the subplots. Results indicate that shading resulted in the decrease of daytime temperature by 5.7˚C as an average for both seasons; thus a significant increasing was found in leaf contents of macro nutrients (Nitrogen, Phosphorous, and Potassium), and micro nutrients (Iron, Zinc and Boron), except the Iron content in 2018 growing season. Furthermore, shading improved significantly the reproductive growth and tomato yield. Among the plant nutrition programs, the integrated nutrient management (INM) including the application of organic substances, bio inoculum of AMF and 50% of the recommended dose of chemical fertilizers; lead to the enhancement of nutrients content, reproductive characteristics and plant yield. Generally, combination of both shading and INM showed positive effects on plants nutrient status and persisting balance on tomato flowering growth and fruits yield.

A field experiment was conducted during kharif 2011 on experimental farm of the College of Post Graduate Studies (CAU–Imphal), Umiam (Meghalaya) to evaluate the effect of integration of green manuring, FYM and fertilizers as integrated nutrient management (INM) practices on growth and developmental behaviour of quality protein maize cultivar QPM 1. The data revealed that comparatively higher amount of primary nutrients were added in green manured maize plots in comparison to non green manured treatments. Green manuring also left a positive response on plant height, CGR, RGR leaf area, and dry matter accumulation in plants though the difference between green manured and non-green manured treatments was at par. Treatments 75 % RDF + 5 t FYM ha-1, 50 % RDF + 7.5 t FYM ha-1, 100 % RDF ha-1 and 75 % RDF + 2.5 t FYM ha-1 recorded significantly higher values of all the above said growth parameters over 50 % RDF + 5 t FYM ha-1 and control treatments. At all stages of observations, the maximum dry matter was associated with RDF (recommended doses of fertilizers) which was at par with 75 % RDF + 5 t FYM ha-1, but significantly higher over the plant dry weight recorded from all remaining treatments. A Significant difference in CGR at 30 – 60 and 60 – 90 DAS stage and in RGR at 90 DAS - harvest stage was observed due to various combinations of recommended dose of fertilizer with different doses of FYM. Number of days taken to attain the stages of 50% tasselling, silking and maturity did not differ significantly due to green manuring. However, treatment 75 % RDF + 5 t FYM ha-1 took significantly lesser number of days for these stages than other treatment combinations. The superiority of the treatment 75 % RDF + 5 t FYM ha-1 indicated a possibility of substituting 25% of RDF with 5 t FYM ha-1 without any loss in dry matter accumulation in plants of the quality protein hybrid maize in mid-hill ecosystems of Meghalaya.

Yield Gap

In this study, we aimed to improve rice farmers’ productivity and profitability in rainfed lowlands through appropriate crop and nutrient management by closing the rice yield gap during the dry season in the rainfed lowlands of Indonesia. The Integrated Crop Management package, involving recommended practices (RP) from the Indonesian Agency for Agricultural Research and Development (IAARD), were compared to the farmers’ current practices at ten farmer-participatory demonstration plots across ten provinces of Indonesia in 2019. The farmers’ practices (FP) usually involved using old varieties in their remaining land and following their existing fertilizer management methods. The results indicate that improved varieties and nutrient best management practices in rice production, along with water reservoir infrastructure and information access, contribute to increasing the productivity and profitability of rice farming. The mean rice yield increased significantly with RP compared with FP by 1.9 t ha–1 (ranges between 1.476 to 2.344 t ha–1), and net returns increased, after deducting the cost of fertilizers and machinery used for irrigation supplements, by USD 656 ha–1 (ranges between USD 266.1 to 867.9 ha–1) per crop cycle. This represents an exploitable yield gap of 37%. Disaggregated by the wet climate of western Indonesia and eastern Indonesia’s dry climate, the RP increased rice productivity by 1.8 and 2.0 t ha–1, with an additional net return gain per cycle of USD 600 and 712 ha–1, respectively. These results suggest that there is considerable potential to increase the rice production output from lowland rainfed rice systems by increasing cropping intensity and productivity. Here, we lay out the potential for site-specific variety and nutrient management with appropriate crop and supplemental irrigation as an ICM package, reducing the yield gap and increasing farmers’ yield and income during the dry season in Indonesia’s rainfed-prone areas.

One of the most challenging topics for the sustainable agriculture is how to decrease high fertilization rates. A pot experiment, exploring the effects of zeolite (ZEO) and/or vermiculite (VER) as soil amendments, comparing to the soil application of a controlled release fertilizer (CRF), was realized in chestnut plants. Various parameters related to soil fertility, and plant growth, nutrition, and physiology were investigated to gain knowledge towards more sustainable management. After ZEO application and in comparison to CRF, an impressive boost in soil K was achieved. Moreover, soil P and Zn levels were higher in the VER-treated soil, compared to CRF. Leaf K and Ca concentrations were significantly higher in ZEO, compared to the VER treatment; the highest foliar N and Zn concentrations were measured in CRF and VER, respectively. However, significantly lower foliar Mn and Cu were found in VER. The highest root biomass produced in the ZEO treated plants. For most nutrients, their total uptake per plant was higher in CRF and ZEO. Finally, photosynthetic rates were higher in VER (mainly due to non-stomatal factors) and CRF (mainly due to stomatal factors). Our data open a discussion towards the application of ZEO and/or VER as soil amendments in chestnut nurseries and orchards, aiming at partially decreasing fertilization rates and boosting sustainable nutrient management.
