The Government

The government of Nepal has recommended blanket fertilizer application for rice cultivation, which results in lower nutrient use efficiency (NUE) particularly under rainfed conditions. With the aim of finding an appropriate nutrient management practices concerning rice production and profitability, a field experiment was conducted during rainy season of 2017 and 2018 at Kavrepalanchowk and Dang district of Nepal. Altogether, five treatments comprising various nutrient management practices viz. Nutrient Expert Model (NE), use of Leaf Color Chart (LCC), Government Recommended Fertilizer Dose (GON), Farm Yard Manure (FYM), and Farmers’ Field Practice (FFP), were laid out in RCBD with four replications in farmers’ fields. The analysis of variance showed significant difference between treatments for test weight and grain yield in Kavrepalanchowk whereas all traits except number of effective tillers were significant in Dang. The significantly higher grain yield and harvest index were obtained in NE, followed by LCC; and the overall straw yield was highest in LCC, followed by NE in both the locations. Also, yield gap analysis suggested the NE had 44.44% and 23.97% increase in yield as compared to FPP in Kavrepalanchowk and Dang, respectively. The combined analysis with Best Linear Unbiased Estimator revealed the interaction of nutrient management and location significantly effects the straw yield and harvest index across both the locations. The estimated mean straw yield and harvest index were 10.93 t/ha and 34.98%, respectively. Both correlation study and biplot of principal component analysis signaled grain yield had positive correlation with all other traits. Furthermore, the net revenue was maximum for NE, followed by LCC in both the locations. The benefit: cost ratio was highest for NE which was 1.55 in Kavrepalanchowk and 2.61 in Dang. On the basis of these findings, NE and LCC can be effectively used as nutrient management practice by the farmers to obtain maximum production and profitability in Rice.

Rainfed Wheat

The improvement in grain yield of wheat throughout Australia through both breeding and management has been impressive. Averaged across all farms, there has been an approximate doubling of yield per unit area since ~1940. This has occurred across a broad range of environments with different rainfall patterns. Interestingly, the gain in the driest years (9 kg ha–1 year–1 or 0.81% year–1) has been proportionally greater than in the most favourable years (13.2 kg ha–1 year–1 or 0.61% per year) when expressed as yield relative to 2012. These data from all farms suggest that further yield progress is likely, and evidence is presented that improved management practices alone could double this rate of progress. The yield increases achieved have been without any known compromise in grain quality or disease resistance. As expected, improvements have come from both changed management and from better genetics, as well as from the synergy between them. Yield improvements due to changed management have been dramatic and are easiest to quantify, whereas those from breeding have been important but more subtle. The management practices responsible have largely been driven by advances in mechanisation that enable direct seeding, more timely and flexible sowing and nutrient management, and improved weed and pest control, many of which have been facilitated by improved crop sequences with grain legumes and oilseeds that improve water- and nutrient-use efficiency. Most of the yield improvements from breeding in Australia have come from conventional breeding approaches where selection is almost solely for grain yield (together with grain quality and disease resistance). Improvements have primarily been through increased harvest index (HI), although aboveground biomass has also been important. We discuss future opportunities to further increase Australian rainfed wheat yields. An important one is earlier planting, which increases resource capture. This will require knowledge of the genes regulating phenological development so that flowering still occurs at the optimum time; appropriate modifications to sowing arrangements and nutrient management will also be required. To improve yield potential, we propose a focus on physiological traits that increase biomass and HI and suggest that there may be more scope to improve biomass than HI. In addition, there are likely to be important opportunities to combine novel management practices with new breeding traits to capture the synergy possible from variety × management interactions. Finally, we comment on research aimed at adapting agriculture to climate change.

The study was conducted in two locations of coastal districts Patuakhali and Satkhira during 2012 and 2013 T. Aman season. Stress tolerant rice varieties along with nitrogen application using prilled urea (PU), leaf color chart (LCC), urea super granule (USG), and rice crop manager (RCM) software based nitrogen (N) dose were examined. The objectives of the study were to identify the response of saline tolerant varieties to N fertilization on grain yield and profitability. Among the tested varieties, grain yield of BRRI dhan40, BRRI dhan41 and BRRI dhan54 were higher compared to BRRI dhan52 and BRRI dhan53 irrespective of location. There were no significant difference among the better performed varieties. Interaction effect of yield was significant in 2013 at Patuakhali but insignificant in both the locations in 2012. During 2013 in Patuakhali, the interaction effect of BRRI dhan40 × USG and BRRI dhan41 × USG produced higher grain yield and total N uptake. In Satkhira BRRI dhan54 and BRRI dhan40 performed better and produced higher grain yield and N uptake. Among the N application treatments USG application was the best compared to either LCC or RCM. The combination of BRRI dhan54×USG and BRRI dhan41×USG had more economic gains in both 2012 and 2013 in Patuakhali. The combination of BRRI dhan52×USG and BRRI dhan41×LCC appeared as themost profitable in Satkhira during 2013. Integration of saline tolerant varieties along with USG application could improve the yield of saline tolerant rice in saline environmentBangladesh Rice j. 2017, 21(1): 77-89

A two years field experiment was carried out in sandy loam soil during rainy (Kharif) seasons in 2019-2020 at CRC farm of sardar vallabhbhai patel university of agricultural & technology, Meerut, Uttar Pradesh to evaluate the various Planting techniques and integrated nutrient management on yield and soil health of rice (Oryza sativa L.) under rice- wheat copping system. The treatments comprised of two Planting techniques i.e., E1-Conventional puddled transplanted rice (CT- TPR), E2- Wide bed Transplanted rice (W Bed-TPR) and Nine Nutrient management practices {N1- Control, N2- 100% RDF + ZnSO4 25 kg ha-1, N3- 125% RDN + ZnSO4 25 kg ha-1, N4- STCR based NPK application + ZnSO4 25 kg ha-1, N5- N2+ FYM  (5 t ha-1), N6- N2+ FYM  (5 t ha-1) + PSB (5 kg ha-1)+ Azotobactor 20 kg ha-1, N7- 75% RDN + FYM (5 t ha-1) + ZnSO4 25 kg ha-1, N8-75% RDN + FYM (5 t ha-1) + PSB (5 kg ha-1) + Azotobactor 20 kg ha-1 +  ZnSO4 25 kg ha-1, N9- Organics Practices @ FYM (30 t ha-1)+PSB (5 kg ha-1) + Azotobactor 20 kg ha-1 + ZnSO4 25 kg ha-1} are laid down in Factorial Randomized block design and replicated thrice. The results indicated that among the different Planting techniques (PTs), conventional puddled transplanted rice (E1, CT-TPR) was recorded significantly higher grain yield (40.4 & 41.3 q ha-1), straw yield (62.7 & 63.8  q ha-1), NPK content and uptake and also improved soil health status ie., available NPK, organic carbon and other physical properties i.e, Bulk density, EC, pH  in soil than wide bed transplanted rice (E2, W Bed-TPR) during both years of kharif 2019 & 2020 respectively. Among the nutrient management practices, the N6 (100% RDF + ZnSO4 25 kg ha-1 + FYM  (5 t ha-1) + PSB (5 kg ha-1)+ Azotobactor 20 kg ha-1 ) treatment produced significantly higher grain yield (49.0 & 50.2 q ha-1), straw yield (81.2 & 82.8 q ha-1), NPK content and uptake, and available NPK organic carbon in soil than the other treatments, which were comparable to the N3 (125% RDN + ZnSO4 25 kg ha-1) treatment and the lowest in the control treatment  N1, respectively. Thus, the results suggest that inclusion of inorganic fertilizer along with organic manure (FYM) enhanced the rice yield Therefore, application of conventional puddled transplanted rice (E2, CT-TPR) along with N6 (100% RDF + ZnSO4 25 kg ha-1 + FYM  (5 t ha-1) + PSB (5 kg ha-1)+ Azotobactor 20 kg ha-1 ) found beneficial to increase productivity and soil health of rice crop.

Frontline demonstration was taken up in farmers’ holdings of Dharmapuri district, Tamil Nadu, India during kharif 2015 to create awareness among the farmers and demonstrate the improved production technologies in finger millet. The integrated crop management practices including cultivation of drought tolerant and short duration finger millet variety ML 365, integrated nutrient management, integrated pest and disease management practices were demonstrated and compared with the existing farmers practice followed in Finger millet cultivation. Results showed that demonstration of finger millet variety ML 365 with integrated crop management practices recorded higher grain yield of 2100 kg/ha and farmers practice recorded lower yield of 1730 kg/ha. Adoption of integrated crop management practices increased the grain yield of finger millet to the tune of 21.7 per cent compared to farmers practice. Farmers earned higher net income of Rs.14244/ha through the demonstration and Rs.10018/ha with farmers practice. Besides, farmers realized higher benefit cost ratio (1.58) through the demonstration compared to farmers practice (1.46). Thus, the frontline demonstration of improved variety with crop management practices increased the grain yield and net income of the farmers growing finger millet under rainfed condition. In the present study, potential of the improved variety and technologies were demonstrated systematically and scientifically in the farmers field along with farmers practice for further adoption by farming community in large scale.

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

Hybrid Maize

Poor nutrient management is one of the key factors contributing to decline in the productivity of maize in Nepal. Few studies have been done on developing site and variety specific fertilizer recommendation. Therefore, a field experiment was conducted at National Maize Research Program (NMRP) Rampur, Chitwan during winter season in September 2016 to study the response of hybrid maize (RML95/RML96) to different doses of soil application of nitrogen (N) and phosphorous (P). The treatments included were 120:60, 120 :( 40+20), 160:60, 160 :( 40+20), 200:60, 200 :( 40+20), 240:60, and 240 :( 40+20) N: P kg ha-1. Potassium fertilizer was fixed and applied as per the Government recommendation i.e., 40 kg K ha-1.Eight treatments were replicated three times in randomized complete block design and maize was planted in six rows of four meter long plot. The research findings revealed that each level of N significantly increased grain yield up to 240 kg N ha-1. The grain yield (8.8 t ha-1) obtained under 240 kg N ha-1 was significantly higher than that obtained under 120,160 and 200 kg N ha-1. However, the results revealed that split application of P failed to bring about any significant difference in the grain yield as well as yield parameters of maize. We can, thus conclude that the addition of increasing rate of N increases the yield and yield attributing characters of maize.  Int. J. Appl. Sci. Biotechnol. Vol 5(4): 537-541

AbstractA field experiment was carried out in sub-tropical climate of Bhimdattanagar, Kanchanpur to assess the effect of site specific nutrient management approach in productivity of spring rice. The experiment was carried in single factor randomized completely block design with four replication, in four different farmer’s field, each farmers’ field as single replication. The seedlings were grown in the mat nursery bed and transplanted in the experimental plots with different nutrient management practices. Nutrient management practices were Site Specific Nutrient Management with Nutrient Expert dose (SSNMNE)(109:28:38 kg NPK/ha), Government recommendation dose (100:30:30kg NPK/ha +6 ton FYM), Farmer’s field practice (FFP)(different among farmers) with three omission plots viz. omission of Nitrogen (0:28:38 kg NPK/ha), Omission of Phosphorus (109:0:38 kg NPK/ha) and Omission of Potassium (109:28:0 kg NPK/ha). SSNM-NE dose was obtained by household survey in the respective area and using nutrient expert model. The growth parameters, yield, yield attributing traits and total cost of production were recorded. Data were analyzed using Duncan’s Multiple Range Test (DMRT) in Genstat. Result indicates that the highest grain yield (5.81 t/ha) was obtained from SSNM-NE which was statistically at par with government recommendation (5.54 t/ha). Similarly, thousand grains weight, straw yield in the experiment 23.20g, 6.90t/ha were significantly higher in SSNM-NE respectively. Straw yield, grain yield and thousand grain weight of SSNM-NE were found to be statistically at par with government recommendation. The economic analysis revealed that higher B: C ratio (1.91), net return and gross return were higher in SSNM-NE.

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.
