Delayed Flowering

Mango cv. Alphonso is established on more than 90 per cent of area in Konkan region of Maharashtra. Early flowering is for early harvest which assures premium rate in market. In recent years climatic aberrations such as delayed rains especially during initiation of flowering badly affected the performance of Alphonso. The delayed flowering further delay fruit development and harvesting. The late harvested fruits often trapped in early rains and fetches low market price. An attempt was made to estimate benefit ratio and net returns of various non-chemical approaches for mango cv. Alphonso in relation to early induction of flowering which lead to early harvesting to earn lucrative market price. The experiment entitled “Economics of chemical and non-chemical approaches for induction of early flowering in mango cv. Alphonso” which was conducted at college of Horticulture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli during the year 2018-19 and 2019-20. Experiment was laid out in randomized block design with seven treatments viz., T1- removal of new shoots, T2- removal of old shoots below new, T3- foliar spray of paclobutrazol @ 500 ppm, T4- foliar spray of paclobutrazol @ 1000 ppm, T5- foliar spray of ortho-phosphoric acid @ 0.5 %, T6- foliar spray of ortho-phosphoric acid @ 1 % and T7- control which were replicated at thrice. From the pooled analysis, early induction of flowering was rapid in T1(35.83 days) and had maximum yield (6.19 t/ha), higher gross return (Rs.309657), maximum net profit (Rs.217781.70) and highest B:C ratio (3.37) which was followed by T2 (3.34), T3 (2.99) and T4 (2.75). The minimum yield (2.90 t/ha), gross return (Rs. 124860), minimum net profit (Rs. 65509.20)with minimum B:C ratio were found in control.

Quantification of Avoidable Yield Losses in OilseedBrassicaCaused by Insect PestsA six year field study was conducted from 2001-2002 to 2006-2007 at Punjab Agricultural University, Ludhiana, India to study the losses in seed yield of differentBrassicaspecies (B. juncea, B. napus, B. carinata, B. rapaandEruca sativa) by the infestation of insect pests. The experiment was conducted in two different sets viz. protected/sprayed and unprotected, in a randomized block design, with three replications. Data on the infestation of insect pests, and seed yield were recorded at weekly intervals and at harvest, respectively. The loss in seed yield, due to mustard aphid and cabbage caterpillar, varied from 6.5 to 26.4 per cent.E. sativasuffered the least loss in seed yield and harboured the minimum population of mustard aphid (2.1 aphids/plant) and cabbage caterpillar (2.4 larvae/plant). On the other hand,B. carinatawas highly susceptible to the cabbage caterpillar (26.2 larvae/plant) and suffered the maximum yield loss (26.4%).

The effect of molybdenum (Mo) on common bean grown in desiccated corn stover in a no-tillage system was evaluated under two application modes: Mo mixed with the desiccant glyphosate and Mo direct spray to the bean leaves. The treatments (four replicates) were assigned to a completely randomized block design in a split-plot arrangement with the application of Mo (0, 100, 200, 400 and 800 g ha-1) mixed with glyphosate in the main plots and Mo foliar spray (0 and 100 g ha-1) in the sub-plots. The field experiments were carried out in 2009 and 2010 in the municipality of Coimbra, Minas Gerais State, with the common bean cultivar Ouro Vermelho. Mo mixed with glyphosate had neither an effect on common bean yield nor on the Mo and N contents in leaves, however it increased the Mo and N contents in seeds. Application of Mo via foliar spray increased Mo content in leaves and Mo and N contents in seeds. The reapplication of molybdenum with glyphosate for desiccation in subsequent crops caused a cumulative effect of Mo content in bean seeds.

This study was carried out to determine whether the yield of soybean cultivars and the severity of Asian Soybean Rust (ASR) are influenced by foliar spray of silicon exclusively or along with a fungicide mixture, as well as the economic viability of their use for a sustainable crop. The experiment was performed in randomized-block design, five replicates, two soybean cultivars and (2×6) + 2 factorial arrangements: S1 (AlSi at R1 + R4); S2 (AlSi at R1 + R5.1); S3 (AlSi at R1 + FM at R4); S4 (FM at R1 + AlSi at R4); S5 (AlSi at R1 + FM at R5.1); S6 (FM at R1 + AlSi at R5.1); NC and PC (negative and positive control). The economic evaluation and sensitivity analysis were undertaken for Anta 82 RR. There was no interaction effect between the factors, and cultivar CD 2737 had a higher yield. ASR was less severe in CD 2737, and S3 and S5 provided the lowest disease severity. Exclusive spray of aluminum silicate was able to reduce the number of lesions with uredinia, open uredinia and uredinia per lesion. S3 increased grain yield, resulting in higher revenues and a 66.1% gross margin. Sensitivity analysis revealed that S3 was profitable in all scenarios.

The combination of consumer’s ongoing demand for chia (Salvia hispanica L.) alongside the increased demand for regionally produced food products provided the impetus for this study. Its aim was to test if a regional cultivation of new chia genotypes, which were adapted to day lengths greater than 12 hours, is feasible under Central European conditions. Therefore, three early flowering chia genotypes (Sahi Alba 914, W13.1, G8) were cultivated in a randomized block design at two experimental stations in Southwestern Germany (Ihinger Hof, Eckartsweier) over the course of two years (2015, 2016). Mean yields ranged from 100 to 1290 kg ha−1. Mucilage content ranged from 9.5% to 12.2%, while the crude protein content ranged from 17.2% to 25.0%. Crude oil content fell in the range of 30.9–33.7% and the PUFA:SAT ratio ranged from 4.0 to 9.4, whereas the omega6:omega3 ratio varied from 0.27 to 0.5. As chia seed yields surpassed yield levels obtained by their countries of origin and as quality parameters obtained, were in line with the genotypes cultivated in their countries of origin, it can be assumed that a regional chia production in Southwestern Germany offers great potential, being ecologically and economically profitable.

AbstractIn recent years, producers of agricultural products have increased the use of chemical fertilizers per unit area. The goal of this research was to analyze the interaction of genotype in treatment (NPK fertilizer) on grain yield, protein content, oil content, and the starch content on 13 maize hybrids using analysis by the model of additive and multiplier effects AMMI and to evaluate genotypes, treatments, and their interactions using biplot in Hungary. Treatments include NPK0 (N: 0 kg/ha, P2O5:0 kg/ha, K2O: 0 kg/ha), NPK1 (N: 30 kg/ha, P2O5: 23 kg/ha, K2O: 27 kg/ha), NPK2 (N: 60 kg/ha, P2O5: 46 kg/ha, K2O: 54 kg/ha), NPK3 (N: 90 kg/ha, P2O5: 69 kg/ha, K2O: 81 kg/ha), NPK4 (N: 120 kg/ha, P2O5: 92 kg/ha, K2O: 108 kg/ha), NPK5 (N: 150 kg/ha, P2O5: 115 kg/ha, K2O: 135 kg/ha) in four replications based on complete randomized block design in 2019. The NPK fertilizer effects indicate that the fertilizers are different on yield genotype. AMMI analysis showed that there was a significant difference between genotypes, treatment, and the interaction effect of genotype * treatment at one percent. Besides, the maximum yield had Loupiac and NPK3 on grain yield, Loupiac and NPK2 on oil content, P0023, and NPK3 for starch content, DKC 3/ES4725 (DKC4725) and NPK3 for protein content. Also, GGE biplot analysis indicates that had maximum grain yield in Loupiac, protein content in P9978, oil content in MV Maronetta, and starch content in Sushi.

A field experiment was conducted during kharif season of 2015 on silty clay loam soil at MPKV, Rahuri (MS), to study the varying nutrient management levels on productivity and economics of different soybean varieties. The experiment was laid out in factorial randomized block design with 15 combinations of three varieties (KDS-344, JS-9305 and KS-103) and five nutrient management levels ( GRDF, 75% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS, 100% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS, N4: 125% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS and 50:75:30 N, P2O5, K2O kg ha-1 + 5 tons FYM ha-1. The variety KDS-344 and application of nutrient management dose 125% GRDF + 0.5 Grade IInd foliar spray at 30 and 45 DAS recorded significantly the highest growth and yield attributes viz., plant height (cm), number of branches, number root of nodules, number of pod plant-1 and weight of seeds plant-1 (g). The variety KDS-344 recorded highest grain and stover (3.66 and 4.64 t /ha) yield and highest economic indices like cost of cultivation (40,623), net monetary returns (87355) and net returns per rupee invested (3.17). The grain yield (4.34 t/ha) and stover yield (4.53 t/ha) of soybean was significantly higher by application of fertilizer dose of 125% GRDF + 0.5% Grade IInd foliar spray at 30 and 45 DAS than rest of treatments, but it was also at par with 75% GRDF + 0.5 Grade IInd foliar spray at 30 and 45 DAS and 100% GRDF + 0.5% Grade IInd foliar spray at 30 and 45 DAS. Similarly, variety KDS-344 and application of nutrient levels of 75 % GRDF + 0.5 % Grade IInd foliar spray at 30 and 45 DAS recorded the highest net returns (82756) and net returns per rupee invested (3.24) in soybean due to reduce in cost of cultivation (36931) and nutrient losses.

The potato is one of the most economically important crops in Brazil, and among the items that most cost the production is seed potatoes. The deficiency of one nutrient can interfere with the absorption and accumulation of the others in plants. The aim of this work was to quantify the optimal potassium (K) dose for minituber basic seed potato yield in hydroponic system. The experiment was installed in a greenhouse with the Agata cultivar minitubers. The treatments consisted of five doses of K (0.0; 2.5; 5.0; 7.5 e 10.0 mmol L-1) with four repetitions. The experimental design was a randomized block design. Data were submitted to analysis of variance and regression. The number of tubers, fresh mass, classification and dry mass were measured. The content of K and content other nutrients in the seed potato tubers were also evaluated. In the hydroponic systems, the maximum yield per plant was 48.41 tubers obtained with 6.15 mmol L-1 of K and maximum mass of fresh matter was 646.6 g.

ABSTRACT This study aimed to evaluate the effect of nitrogen (N) and potassium (K) fertilization in yield and contents of macronutrients in heliconia plants (Heliconia psittacorum x Heliconia spathocircinata Aristeguieta) cv. Golden Torch. The experiment was set in a randomized block design, in a 4 x 4 factorial, corresponding to N doses (0, 120, 180 and 240 g of N hole-1) and K doses (0, 120, 180 and 240 g of K2O hole-1) with four replicates and five rhizomes per plot, under field conditions. After one year of cultivation, yield (number of flower stems per square meter) and the leaf contents of N, P, K, Ca, Mg and S were determined. The applied N doses did not influence either yield or the leaf contents of the evaluated macronutrients. K fertilization favored the increase in leaf K content and the decrease in the contents of P, Ca and Mg in leaves of heliconias. Under the conditions of this experiment, it is recommended to apply 161.46 g of K2O hole-1 for a maximum yield of 9.89 stems m-2 per month.
