Rice (Oryza sativa L.) is a dominant staple food crop of Nepal which production and productivity is significantly declining compared to several years due to inappropriate nutrient management practices. A field experiment was conducted at Lamahi, Dang to evaluate the performance of hybrid rice(US-305) under rain fed condition with five precision nutrient management practices [Viz: Nutrient Expert® -Rice (NE) recommendation; Leaf Color Chart (LCC) N and Nutrient Expert (P and K); Nutrient Expert (N) and Farmers Fertilizer Practices (P and K); Farmers Fertilizer Practices (FFP) and Government Recommendation (GR)] replicated four times in RCBD design during June to October, 2018. The experimental finding showed that SSNM based Nutrient Expert® -Rice (NE) recommendation gave higher grain yield (6.36 ton ha-1) and straw yield (12.62 ton ha-1) which leads to highest gross return (NRs 242,498) and B: C ratio(3.08). Between the treatments Nutrient Expert® -Rice (NE) recommendation was excellent to growth parameters like plant height, crop growth rate, relative growth rate and leaf area index over FFP. Further, Nutrient Expert® -Rice (NE) recommendation gave significantly higher effective tiller m-2(354.50), panicle length (26.31), panicle weight (81.50), filled grain (390) and fertility (87.56%) over FFP. Nutrient Expert® -Rice (NE) recommendation has increased the grain yield by 23.97% with yield difference of 1.23 ton ha-1 and straw yield by 39.44 % with yield difference of 3.57 ton ha-1 in comparison with FFP. Hence the experiment concluded that site specific nutrient management recommendation that accounts Nutrient Expert® -Rice and leaf color chart could be the practical decision tool for making authentic fertilizer recommendation.

Eight treatment combinations comprising of K1: RDF i.e.,120:60:60 kg N:P2O5:K2O ha-1 (1/3rd N each at transplanting (TP), active tillering (AT) and panicle initiation (PI), K2:50 % RDF (1/3rd N each at TP, AT and PI) + FYM 5 t ha-1, K3:75 %RDF (1/3rd N each at TP, AT and PI) + FYM 5 t ha-1 , K4:100 % RDF (1/3rd N each at TP, AT and PI) + FYM 5 t ha-1, K5:100% RDF (½ N at TP, ¼th N at AT, ¼ th N at PI) + FYM 5 t ha-1 , K6:100 % RDF (¼th N at TP, ½ N at AT, ¼ th N at PI) + FYM 5 t ha-1, K7:50% RDF (1/3rd N each at TP, AT and PI) + FYM 10 t ha-1 and K8: FYM 5 t ha-1 + Vermicompost (VC) 2.5 ha-1 + Azospirillum 5 kg ha-1 + PSB 5 kg ha-1 were applied to hybrid rice var. Ajay grown under SRI method during kharif season and during rabi season mustard was grown taking the eight kharif season plots as main plot and three nutrient management practices viz., R1:100% RDF (40:20:20 kg N:P2O5:K2O ha-1), R2: 50% RDF + Azotobacter and R3-control (no fertilizer) in sub-plot and replicated thrice. The results revealed that application of 100% RDF + FYM 5 t ha-1 to rice registered significantly higher grain (7545 kg ha-1) and straw yield (7241 kg ha-1) of rice and higher seed yield (806 kg ha-1), stover yield(1423 kg ha-1), harvest index (36.3%) of subsequent mustard crop and system rice equivalent yield (9629 kg ha-1). Application of 50% RDF with BF to mustard recorded higher soil organic carbon and pH than RDF and control. The decrease in bulk density was more in the plots applied with 50% RDF+10t FYM to kharif rice (1.38 Mg m-3) and 50% RDF + BF to rabi mustard (1.41 Mg m-3). The available N, P and K content of soil increased to 237.6, 17.1 and 374.9 kg ha-1 from its initial value 148.2, 12.7 and 352.4 kg ha-1, respectively, at the end of second year with application of 50% RDF + BF to mustard.

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.
