Abstract Background: Teff (Eragrostis tef (Zucc.) Trotter) is an important grain crop, but a paucity of research means that the mean yield is below 1.5 t ha−1. Its high genetic diversity has not been exploited to improve its yield potential. Previous efforts at increasing yield were based entirely on phenotypic, morphologic, and agronomic merits. However, photosynthetic capacity has been neglected, so its possible contributions to yield improvements remain unexplored. Results: We grew 15 teff cultivars in a controlled environment to explore variations in photosynthetic capacity and nitrogen use efficiency (NUE), and examined the relationships of gas exchange and NUE before anthesis with growth and yield attributes. Substantial differences were found in leaf photosynthetic rate (19 ± 9 μmol m−2 s−1, mean ± SD), stomatal conductance (0.11 ± 0.09 mol m−2 s−1), and transpiration rate (2.4 ± 1.3 mmol m−2 s−1). The cultivars differed significantly (P < 0.05) in both NUE (190 ± 227 g m−2) and photosynthetic NUE (59 ± 34 µmol g−1s−1). On average, the plants partitioned 29% of N to leaf, 28% to panicle, and 13% to stem before anthesis. Yield and biomass production were closely associated with photosynthetic capacity and NUE. Clustering of the cultivars on the basis of photosynthesis, NUE, growth, and yield indicates wide variations in photosynthetic capacity and NUE in the wider teff gene pool that should be exploited. Conclusion: We conclude that leaf photosynthesis and NUE are positively related to yield and biomass production in teff.

All India coordinated Research Project on linseed conducted a field experiment on Agriculture Farm, College of Agriculture, Nagpur under Dr. PDKV, Akola, Maharashtra during Rabi Season of 2019-20 in Factorial Randomized Block Design with three replication. Three genotypes NL – 356, JLS-95, T-397 were tested with three nutrient levels i.e. 50 % RDF, 100% RDF and 150 % RDF. The result revealed yield potential of the entry NL-356 was 26% highest over JLS-95 and 13% more on T-397 under rainfed condition. However, the increase in nutrient level from 50 % RDF to 150 % RDF influence the growth and yield attributes which favours the increase in yield. Therefore, it is concluded that genotype NL 356 with 100 % RDF achieve higher growth rate i.e. plant height, number of branches as well as yield attributes number of capsules per plant, number of seed per capsule and highest NMR and B:C ratio.

AbstractCrop cultivation provides ecosystem services on increasingly large fields. However, the effects of in-field spatial heterogeneity on crop yields, in particular triticale, have rarely been considered. The study assess the effects of in-field soil heterogeneity and elevation on triticale grown in an intensively cropped hummocky landscape. The field was classified into three soil classes: C1, C2, and C3, based on soil texture and available water capacity (AWC), which had high, moderate, and low yield potential, respectively. Three elevations (downslope (DS), midslope (MS), and upslope (US)) were considered as the second study factor. An unbalanced experimental design was adopted with a factorial analysis of variance for data analysis. Temporal growth analysis showed that soil classes and elevation had significant effects. Generally, better growth was observed in C1 compared to that of C3. DS had a lower yield potential than that of MS and US. In addition, the interactive effect was confirmed, as triticale had poor growth and yield in C3 on the DS, but not on US. Crop physiological parameters also confirmed the differences between soil classes and elevation. Similarly, soil moisture (SM) content in the plow layer measured at different points in time and AWC over the soil profile had a positive association with growth and yield. The results confirmed that spatial differences in AWC and SM can explain spatial variability in growth and yield. The mapping approach combining soil auguring techniques with a digital elevation model could be used to subdivide fields in hummocky landscapes for determining sub-field input intensities to guide precision farming.

Wheat Genotypes

Understanding how changing environment and cultivars influence crop phenology and potential yield is essential for crop adaptation to future climate change. Plant Genetic Diversity (PGD) provides the basis for survival in plants in nature and for crop improvement. Under changing climate scenario and increase in population pressure, wheat genotypes with attributes such as; short duration, lesser water loving, and abundant yield potential are of considerable importance. The present study was designed to evaluate best wheat genotypes which may better perform under the changing climatic conditions of southern Punjab, Pakistan. A field trial to study the comparative performance of newly evolved four genotypes; Millat-2011, Faisalabad-2008, Punjab-2011 and AARI-2011 was conducted at two different agro-climatic conditions of Dera Ghazi Khan, Punjab, during crop season, 2013-2014. The design used was randomized complete block with three replicates. Plot size was maintained as (4x 6m) and (2.5x 6m) respectively, for site-1 2. Seed rate of 125 kg ha-1 was used. The recommended dose of NPK (128-114-62 Kg/ha), irrigation, weed control methodology and all other agronomic practice were kept the same for all the treatments in both sites. Statistical analysis of the data was carried out by studying different yield components (Germination count m-2, Number of Fertile tillers m-2, No. of spikelets spike-1, Plant height at maturity, Spike Length, No. of grains spike-1, 1000 grain weight and Grains yield) and their means were separated by using the least significance difference test. As per results achieved from the experiment, performance (growth and yield attributes) of genotype Millat-2011 was best as compared to all other genotypes tested under local condition. Millat-2011 recorded a significant increase in all growth and yield variables, including germination, grains number, test weight and yield of wheat under local conditions as compared to rest three genotypes.

The Impact

Field-based experiments were conducted during wheat cultivation seasons of 2017–2018 and 2018–2019 to minimize the impact of hidden hunger (micronutrient deficiencies) through agronomic biofortification of two wheat cultivars with zinc and iron. Two spring-planted bread wheat cultivars: Zincol-16 (Zn-efficient) and Anaj-17 (Zn-inefficient with high-yield potential) were treated with either zinc (10 kg/ha), iron (12 kg/ha), or their combination to study their effect on some growth attributes (plant height, tillers, and spike length, etc.,), productivity, and quality. No application of zinc and iron or their combinations served as the control. Maximum Zn and Fe contents of grains were improved by sole application of Zn and Fe, respectively. A higher concentration of Ca in grains was observed by the combined application of Zn and Fe. Starch contents were found maximum by sole application of Fe. Sole or combined application of Zn and Fe reduced wet gluten contents. Maximum proteins were recorded in Anaj-17 under control treatments. Zincol-16 produced maximum ionic concentration, starch contents, and wet gluten as compared to Anaj-17. Yield and growth attributes were also significantly (p &lt; 0.05) improved by combined application as compared to the sole application of Zn or Fe. The combined application also produced the highest biological and grain yield with a maximum harvest index. Cultivar Anaj-17 was found more responsive regarding growth and yield attributes comparatively. The findings of the present study showed that the combined application of Zn and Fe produced good quality grains (more Zn, Fe, Ca, starch, and less gluten concentrations) with a maximum productivity of bread wheat cultivars.

Sesame cultivars perform differently in various environments comprising specific locations and years. Micronutrient fertilizers increase crop yields and can enhance resistance to environmental hazards and contribute to potential yield. For assessing the effect of environment and micronutrients, field experiments were carried out at three different locations (BARI, URF and NARC) of Pothwar region, Pakistan, in two succeeding years (2014, 2015). Four sesame cultivars and three micronutrients (Zn, B and Mn) with a control treatment were used in RCB design with a split-plot procedure and four replications. The results showed significant differences in the main effects of all tested factors (cultivars, micronutrients, locations and years). Maximum mean values of plant height, capsules plant−1, biomass yield and seed yield were recorded for SG-30, while TH-6 was the lowest for these parameters. Maximum mean values of capsule length, capsule weight, seeds capsules−1 and the weight of 1000 seeds were recorded for TH-6 but vice versa for SG-30. Maximum capsule length and seeds capsule−1 were observed at NARC, while other growth and yield attributes were maximum at BARI and URF, including biomass yield and seed yield. The interactive effect of cultivar × location × year was highly significant for all growth and yield traits except capsule length. Sesame cultivars revealed a differential response for all traits at three locations during both years. Application of micronutrients significantly augmented all growth and yield features of sesame. Micronutrient fertilizers (i.e., ZnSO4 at 10 kg ha−1, borax at 10 kg ha−1 and MnSO4 at 5 kg ha−1) would increase yield and yield-attributing traits in low- or medium-precipitation areas where suitable cultivars have been designated.

Weeds are one of the major problems for farmers in any crop production, which reduce the availability of nutrients, water, sun light to the crop and provide a tough competition to crop. Hence causing severe loss to the crop quality and produce. Weeds are also considered one of the major problems in seed spices. Ajwain is an important seed spice crop grown in Rajasthan, Madhya Pradesh and Andhrapradesh. The research on Ajwain crop is very meagre, it is severely affected by various. biotic and abiotic factors which affects the yield potential significantly. Plant weed competition is one of the major factors, besides insect pest and diseases causing significant yield and quality losses. Ajwain being a rabi crop faces severe competition with the weeds like Chenopodium album, Coronopus didymus, Melilotus spp., Rumex spp., Cyperus rotundus etc. To enhance the yield potential it is must to have an efficient cost-effective weed management modules.Best growth parameters were observed in weed free condition through out growth period treatment. Maximum (98.91percentage) loss in yield was recorded with the treatment, weedy through out under growth period (T9). Weed count and weed biomass was recorded maximum in T9’whereas minimum in T18. Critical period for weed competition in ajwain was found to be 63 days after sowing. Weedy period up to 75 DAS gave tough competition to the crop for growth which was reflected in yield attributes and seed yield of Ajwain. The maximum yield of 638.15kg/ha was obtained with the treatment weed free throughout growth period, this was also found economically viable which resulted in highest gross return of 99987/ha, net returns 66315/ha and B: C ratio of 1.97. The Benefit: Cost ratio of 0.31 and 1.31 was observed for weed free condition up to 90 DAS (T15) and 120 DAS (T17) respectively.

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.

Poor early growth and uneven crop establishment are reported as the major bottlenecks in wide-scale adoption and optimal yield realization of dry direct-seeded rice (DSR). Seed priming can potentially help overcome these problems in DSR. Therefore, laboratory and field studies were conducted at Punjab Agricultural University, Ludhiana, India, during kharif/wet-season 2018 and 2019 to evaluate the effect of different priming techniques on germination, establishment, growth, and grain yield of rice under DSR conditions. The following priming treatments were evaluated: dry non-primed seed (control), hydropriming with distilled water, halopriming with 2.0% potassium nitrate, hormopriming with 50 ppm gibberellic acid (GA3), and osmopriming with polyethylene glycol (PEG)(−0.6 MPa), each with 12 and 24 h priming duration. In 2019, priming treatments were tested under two DSR establishment methods—conventional DSR (sowing in dry soil followed by irrigation) and soil mulch DSR (locally known as vattar DSR) (sowing in moist soil after pre-sowing irrigation), whereas in 2018, priming treatments were evaluated under conventional DSR only. In both years, halopriming and hormopriming resulted in a 7–11% increase in rice yields compared to non-primed dry seed (control). Osmopriming resulted in a 4% yield increase compared to control in 2018 but not in 2019. The higher yields in halopriming and hormopriming were attributed to higher and rapid germination/crop emergence, better root growth, and improvement in yield attributes. Priming effect on crop emergence, growth, and yield did not differ by DSR establishment methods and duration of priming. Conventional DSR and soil mulch DSR did not differ in grain yield, whereas they differed in crop emergence, growth, and yield attributes. These results suggest that halopriming with 2.0% potassium nitrate and hormopriming with 50 ppm GA3 has good potential to improve crop establishment and yield of rice in both conventional and soil mulch DSR systems.
