“…The reason behind this was addition of 50% more recommended dose of fertilizer which resulted in higher readily available soil nutrients and there by higher nutrient uptake at harvest which inturn resulted in enhanced photosynthesis and growth attributes in the treatments. The results are in conformity with Santosh et al [5]; Malo et al [6] and Patel et al [7].…”

The field experiment was conducted during 2018 Kharif at Zonal Agricultural Research Station, Vishwesharaiah Canal Farm, Mandya to study the Effect of different establishment methods and nutrient management practices on growth, yield and economics of rice (Oryza sativa L.). The experiment laid out in a split plot design with three replications. The treatments comprised of three rice establishment methods viz., semi dry, drum seeding & transplanting and five nutrient management practices. Among establishment methods, growth and yield parameters such as LAI at 60 DAS, plant height, dry matter production at harvest, panicles m-2, panicle weight, test weight, grain and straw yields recorded were statistically analyzed at par with each other. Further between nutrient management practices, application of 150% RDIF recorded significantly higher LAI at 60 DAS, plant height, dry matter production at harvest, panicles m-2, panicle weight, test weight, grain and straw yields as compared to rest of the nutrient management practices. Further semi dry and drum seeding of rice recorded higher B:C ratio (2.15) over transplanting of rice (2.10). Similarly, 150% RDIF recorded higher B:C ratio (2.37), but was closely followed by 100% RDIF (2.22).

“…On the basis of results obtained, application of 75 per cent RDF (90:45:30 kg NPK/ha + 25 per cent N through FYM and nutrient supply system was found to be more suitable for higher yield of wheat variety Malviya 234". Malo et al [56] conducted "an experiment to study the effect of inorganic and biofertilizers on growth and yield of rice in New Alluvial zone of West Bengal. The results revealed that the highest plant height, LAI, dry matter accumulation and crop growth rate were observed in 100 per cent RDF which was statistically at par with 75 per cent recommended dose of NP + 100 per cent RDK + Azotobacter chroococcum at 5 kg/ha".…”

The adequate and balanced supply of plant nutrients is of critical importance in improving the productivity of wheat crop. Due to prohibitive cost of chemical fertilizers, Indian farmers, mostly marginal and small, do not supply the recommended doses of nutrients to these energy rich crops, indigenously available organic sources of nutrients have been recorded to enhance the efficiency and reduce the requirement of chemical fertilizers. The nutrients (N, P, K and Zn) can be supplied through fertilizers, organic manures, biofertilizers, bio-stimulants and their combined applications under integrated nutrient management. Wheat varieties differ in their phenology, requirement of thermal and photoperiod units and growth habits which cumulatively determine the varietal adaptation at different locations and sowing times. Therefore, comparative evaluation of varieties suitable for early, normal and late sown conditions is warranted to identify the growth patterns, physiological traits and yield attributes that will favorably influence the grain yield and biomass in wheat under normal and late sown conditions. This review examines response of wheat varieties to integrated nutrient management practices in wheat crop sown under normal and late planting conditions.

“…The current study showed that ethephon application reduced leaf area but increased specific leaf weight, which was also found by several investigators [56,119] who reported that thicker leaves (greater SLW) increased stomatal density, enhanced chlorophyll and protein contents, increased CO 2 exchange rate, and yield of maize. Growing conditions, particularly at changing water levels, might cause variations in accumulated GDDs [120,121]. Overdosages of ethephon application decreased maize GDDs by causing early plant senescence.…”

A major portion of maize is produced under rainfed conditions in the tropics with relatively poor yield because of the unpredictable and irregular distribution of seasonal rainfall, as well as a decline in pre-rainy season rainfall due to climate change, so identification of sustainable production options is utmost needed. Thus, the present studies were conducted in a greenhouse (GH) to ascertain the water stress-tolerant traits of maize and at the field level in the tropical environment of Thailand to see the stimulating possibility of the ascertained traits in a locally popular cultivar using ethephon. Depending on tolerance level, three maize genotypes (Suwan 2301 > Suwan 4452 > S 7328) were tested under different water conditions—well-watered, short-term, and long-term water stress—in the GH. At the field level, the locally popular maize cultivar Suwan 5819 was examined with six ethephon levels (doses in g a.i. ha−1 of ethephon, i.e., T1, 281 at V6 stage; T2, 281 at V6 + 281 at V10 stage; T3, 281 at V10 stage; T4, 562 at V6 stage; T5, 562 at V6 + 562 at V10 stage; T6, 562 at V10 stage) against no ethephon application (T0) under rainfed conditions. Maize suffered from the scarcity of sufficient rainfall during 26–39 days after planting (DAP) and 43–63 DAP in the field. The yield index (YI) was identified from biplot analysis as one of the suitable standards for drought tolerance checks for maize at GH as well as at field level in the tropics. The YI value of observed agro-physio-biochemical traits of maize in GH showed that relative water content (RWC, 1.23), stem base diameter (SBD, 1.21), total soluble sugar (TSS, 1.15), proline (Pr, 1.13), aboveground plant biomass (APB, 1.13), root weight (RW, 1.13), relative growth rate (RGR, 1.15), specific leaf weight (SLW, 1.12), and net assimilation rate (NAR, 1.08) were the most desirable. Efforts were made to stimulate these traits under water stress at the field level. Ethephon application as T1 helped to gain higher kernel yield (KY) (5.26 t ha−1) with the support of higher RWC (90.38%), proline (24.79 µmol g−1 FW), TSS (1629 mg g−1 FW), SBD (24.49 mm), APB (271.34 g plant−1), SLW (51.71 g m−2), RGR (25.26 mg plant−1 day−1), and NAR (0.91 mg cm−2 day−1) compared to others, especially no ethephon application. Furthermore, the attributes SLW, SBD, Pr, heat utilization efficiency (HUE), 100-kernel weight, TSS, electrolyte leakage, and lodging percentage showed a substantial direct effect and significant correlation with KY. Aside from higher KY, ethephon application as T1 tactics resulted in higher values of energy efficiency (1.66), HUE (2.99 kg ha−1 °C days−1), gross margin (682.02 USD ha−1), MBCR (3.32), and C absorption (6.19 t C ha−1), indicating that this practice may be a good option for maize sustainable production under rainfed conditions.
