Background: Among the different production factors, irrigation and nutrient management are of immense importance in Pigeon pea cultivation. Drip irrigation can be considered as an efficient irrigation system to maintain optimum moisture content in the root zone. Split application of fertilizers at appropriate stages of crop growth ensure a regular flow of both water and nutrients resulting in increased growth rate and higher yield. Fertigation proposed as a means to increase efficient use of water and fertilizer to increase yield and sustained irrigated agriculture. The current study aims to study the efficacy of split application of N, P and K on growth, water and nutrient use efficiency, productivity and profitability of Pigeon pea.Methods: The field experiment was conducted at Department of Agronomy Farm, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during three consecutive kharif season of 2016-17, 2017-18 and 2018-19. The experiment was laid out in randomised block design with four replications and eight treatments with an objective to study the efficacy of split application of nutrients on growth, water and nutrient use efficiency, productivity and profitability of Pigeon pea. Result: The results revealed that, all the growth parameters, yield attributes and grain yield of Pigeon pea were substantially enhanced by drip fertigation levels at 125:100:100 per cent recommended NPK than lower fertigation levels (75 and 100%) and over conventional soil application of recommended dose of NPK kg ha-1. Drip fertigation at 125:100:100 per cent recommended dose of NPK ha-1 recorded higher pigeon-pea pooled grain yield of 4053 kg ha-1. The maximum GMR (Rs.226807 ha-1), NMR (Rs.176604 ha-1), B:C ratio (4.52) and highest economic efficiency of Rs.883 day-1 ha-1.

Crop modeling can provide us with information about fertilizer dose to achieve the target yield, crop conditions, etc. Due to conventional and imbalanced fertilizer application, nutrient use efficiency in wheat is low. Estimation of fertilizer requirements based on quantitative approaches can assist in improving yields and nutrient use efficiency. Field experiments were conducted at 20 sites in eastern India (Nadia district of West Bengal) to assess the soil supply, requirement, and internal efficiency of N, P, K, and Zn in wheat. The data were used to calibrate the QUEFTS (Quantitative Evaluation of the Fertility of Tropical Soils) model for site-specific, balanced fertilizer recommendations. The parameters of maximum accumulation (a) and maximum dilution (d) in wheat were calculated for N (35, 100), P (129, 738), K (17, 56), and Zn (21502, 140244). Grain yield of wheat showed statistically significant correlation with N (R2= 0.937**), P (R2= 0.901**), and K uptake (R2= 0.801**). The NPK ratio to produce 1 tonne grain yield of wheat was calculated to be 4.9:1.0:8.9. The relationships between chemical properties and nutrient-supplying capacity of soils were also established. The model was validated using the data from four other experiments. Observed yields with different amounts of N, P, K, and Zn were in good agreement with the predicted values, suggesting that the validated QUEFTS model can be used for site-specific nutrient management of wheat.

Abstract Maize area is rapidly spreading in south India in response to rising demand from the poultry and fish feed industries. The planting of maize during winter season is necessary to increase the total area and production of maize. The present investigation encompassing different sowing windows with different fertility levels revealed that significantly higher winter maize productivity was achieved from first and second week of October planting along with application of 200 % RDF(recommended dose of fertilizer) followed by 150 % RDF. Planting of winter maize during first week of October recorded significantly higher grain yield (8786 kg ha-1) and stover yield (1220 kg ha-1) and was found on par with sowing during second week of October. Among fertility levels, significantly higher grain yield (8320 kg ha -1) and stover yield (1195 kg ha-1) were recorded with application of 200 % RDF and was found on par with application of 150 % RDF. Similarly higher dry matter production, more days for physiological maturity, higher accumulation of growing degree days, photo thermal units and heliothermal units were recorded from crop planted during first and second week of October along with application of either 200 % or 150 % RDF. Further higher nutrient use efficiency was recorded from first and second week October planted crop along with lower fertility level (100 % RDF). Similarly significantly higher output energy, net energy and specific energy were higher from crop planted during first week of planting along with application of 200 % RDF. Also it recorded higher net returns and gross returns Whereas, energy use efficiency and energy productivity were higher with planting during first week of October along with application of 100 % RDF.

Because of using sulphur free fertilizer, rice crop facing tremendous sulphur (S) deficiency throughout the world as well as in Bangladesh. However, farmers of Bangladesh often overlook the importance of sulphur fertilization on rice yield. Therefore, the present study was conducted to investigate the influence of different levels of sulphur on growth, yield attributes and uptake of N, P, K and S by grain and straw of BRRI dhan41 rice variety. The experiment was laid out in randomized complete block design with three replication and eight treatments including control. The result of the study revealed that the highest plant height, panicle length, filled grain was found in T1 (50% RFD of S) treatment, while the utmost number of effective tiller and straw yield was recorded in T5 (150% RFD of S) treatment. Interestingly, maximum grain yield as well as uptake of N, P, K and S by grain and straw was significantly higher in T6 (175% RFD of S) treatment. The highest grain yield of T6 treatment might be due to maximum nutrient use efficiency. However, in all cases control treatment (T0) gave the worst result. The present study clearly indicates that higher rates (175% of the recommended dose) of S along with other fertilizers may be recommended for better growth and yield of BRRI dhan41 in Bangladesh soil.

An experiment was carried out during the Kharif 2002 and 2003, to study the productivity and nutrient use efficiency of hybrid rice (Oryza sativa L.) in response to integrated use of organic and inorganic sources of nutrients at Research farm, IGAU, Raipur (CG). In all 12 treatments, comprising of different N, P and K levels and its conjunction with organic fertilizers were laid out in Randomized Block Design with 3 replications. The results revealed that application of inorganic fertilizer level of 150:80:60 kg NPK ha-1 significantly increased number of active leaf, leaf area, leaf area index and dry matter accumulation at later stages as compared to lower level of inorganic fertilizer. The conjunction of 100:60:40 kg NPK ha-1 along with PM or N blended with CDU found to be equally effective to that of inorganic fertilizer level of 150:80:60 kg NPK ha-1 for above growth parameters. The chlorophyll content during crop period under above level was the highest under said treatment. The highest crop growth rate was observed between 60-90 DAT followed by 90 DAT-harvest and 30-60 DAT, respectively. The per day accumulation of dry matter during 60-90 DAT period was almost three to four times of that accumulated during 30-60 DAT. Thereafter growth rate almost declined till maturity during both the years.The increased concentration of N at different growth stages and its uptake by plant helped in increasing the yield components and grain yield. The critical analysis of grain yield observations revealed that conjunction of lower levels of inorganic fertilizer (100:60:40 or 50:30:20 kg NPK ha-1) along with CDU or PM gave the saving of 50 kg N, 20 kg P and 20 kg K ha-1 for the cultivation of hybrid rice. Moreover, the higher buildup of available N and K has been also observed under said combination of organic and inorganic fertilizer treatments. The application of 150:80:60 kg NPK ha-1 along with PSB gave the highest buildup of available phosphorus. Inorganic level of 150:80:60 kg NPK ha-1 gave the highest production efficiency and productivity rating index, which was followed by application of inorganic fertilizer of 100:60:40 kg NPK ha-1 along with PM and blending of N with CDU, respectively. The application inorganic fertilizer of 50:30:20 kg NPK ha-1 + PM gave the highest nutrient efficiency during both the years. The highest input cost, net profit and per rupee investment was found under 150:80:60 kg NPK ha-1 followed by application of 100:60:40 kg NPK ha-1 along with PM.

The development of rice cultivars with nutrient use efficiency (NuUE) is highly crucial for sustaining global rice production in Asia and Africa. However, this requires a better understanding of the genetics of NuUE-related traits and their relationship to grain yield. In this study, simultaneous efforts were made to develop nutrient use efficient rice cultivars and to map quantitative trait loci (QTLs) governing NuUE-related traits in rice. A total of 230 BC1F5 introgression lines (ILs) were developed from a single early backcross population involving Weed Tolerant Rice 1, as the recipient parent, and Hao-an-nong, as the donor parent. The ILs were cultivated in field conditions with a different combination of fertilizer schedule under six nutrient conditions: minus nitrogen (–N), minus phosphorus (–P), (–NP), minus nitrogen phosphorus and potassium (–NPK), 75% of recommended nitrogen (75N), and NPK. Analysis of variance revealed that significant differences (p < 0.01) were noted among ILs and treatments for all traits. A high-density linkage map was constructed by using 704 high-quality single nucleotide polymorphism (SNP) markers. A total of 49 main-effect QTLs were identified on all chromosomes, except on chromosome 7, 11 and 12, which are showing 20.25% to 34.68% of phenotypic variation. With further analysis of these QTLs, we refined them to four top hotspot QTLs (QTL harbor-I to IV) located on chromosomes 3, 5, 9, and 11. However, we identified four novel putative QTLs for agronomic efficiency (AE) and 22 QTLs for partial factor productivity (PFP) under –P and 75N conditions. These interval regions of QTLs, several transporters and genes are located that were involved in nutrient uptake from soil to plant organs and tolerance to biotic and abiotic stresses. Further, the validation of these potential QTLs, genes may provide remarkable value for marker-aided selection and pyramiding of multiple QTLs, which would provide supporting evidence for the enhancement of grain yield and cloning of NuUE tolerance-responsive genes in rice.
