Field experiment was conducted at farmer field in kadukkarai village, Kanyakumari during February 2021 – April 2021 to evaluate the Effect of foliar nutrition for maximizing the productivity of rice fallow blackgram (Vigna mungo (L). Hepper). Nine treatments were tested in randomized block design with three replications. Among the treatments, application of RDF + Foliar spray of 1% 19:19:19 on 15 DAS + Foliar spray of 1% 12: 61:0 30 DAS + Foliar spray of 1% 13:0:45 on 45 DAS significantly recorded highest grain yield (723 kg ha-1) and haulm yield (2320 kg ha-1). However, the highest gross return (Rs.53, 955), net return (Rs.41, 305) and BC ratio (3.27) were recorded the foliar spray of 1% 19:19:19 on 15 DAS + Foliar spray of 1% 12: 61:0 30 DAS + Foliar spray of 1% 13:0:45 on 45 DAS.

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research experiment was conducted in a farmer’s field at Pudhupalayam, Coimbatore to investigate the effect of foliar application of PPFM, plant growth regulating compounds and nutrients on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2019 (kharif and rabi) season. The treatments include 100% recommended dose of NPK along with foliar application of diammonium phosphate (DAP), brassinolide (Br), salicylic acid (SA) and pink pigmented facultative methylotrophs (PPFM) with different concentration (1%, 2%, 1 ppm, 2 ppm, 50 ppm, 100 ppm, respectively) in addition to control. PPFM and PGRs were sprayed at 30 and 45 days after the sowing of blackgram. Result: The experiment results of the two seasons study revealed that the application of 100% RDF + PPFM @ 2% recorded higher growth characters viz., plant height (cm), number of branches plant-1, leaf area index and yield attributes viz., number of pods plant-1, number of seeds pod-1, pod weight (g), pod height (cm), 100 seed weight (g) and yield viz., grain yield (kg/ha), straw yield (kg/ha) and harvest index (%). As well as the same treatment recorded higher net return and B:C ratio. Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield with a magnitude of 1.91 and 1.67, respectively. Therefore, application of 100% RDF+2% PPFM spray can be recommended as the best technology to improve the yield and economics of blackgram.

Background: Foliar application or foliar nutrition is a technique of feeding plants by applying liquid fertilizer directly to their leaves. Water soluble fertilizers have been introduced exclusively for foliar feeding and fertilization. There is very little information about the foliar application of water soluble fertilizers. There is need for more research in this field. Therefore, foliar nutrition is being recognized as an important method of fertilization in modern agriculture. The current study aimed to study the effect of foliar application of water soluble fertilizers on growth and yield of chickpea (Cicer arietinum L.). Methods: The field experiment was conducted during rabi 2017-18, 11 different treatments were laid out in a randomized block design on clay loam soil. In the field, the data was collected and analyzed and the final result was concluded. Result: The experiment revealed that the growth attributes such as plant height (60.28 cm), number of primary branches (5.22), number of secondary branches (22.93) and dry matter accumulation (241.61 g) were maximum with 75% RDF + foliar application of 2% DAP + 2% Urea + 2% WSF at 60 and 80 DAS (T10) and minimum in control (T1) at harvest stage. Further, seed yield (24.26 q ha-1), stover yield (31.38 q ha-1) and biological yield (55.65 q ha-1) was maximum with 75% RDF + foliar application of 2% DAP + 2% Urea + 2% WSF at 60 and 80 DAS (T10) and minimum in control (T1).

Weed Control Efficiency

Background: Time of pre-emergence herbicide application is an important factor that decides the efficiency of herbicide. If the pre-emergence herbicide is not applied at appropriate time, it may cause ineffective weed control or toxicity to crops. With this background, a field experiment was conducted at TNAU, Madurai to optimize the time of pre-emergence herbicides namely pendimethalin and oxyfluorfen application for effective weed management in irrigated blackgram. Methods: The experiment was laid out in randomized block design with three replication. Treatments were application of pendimethalin at 0.75 kg ha-1 and oxyfluorfen at 0.2 kg ha-1 on 1, 2, 3, 4 days after sowing, weed free check and unweeded check. Result: Results of the study revealed that oxyfluorfen gave maximum weed control efficiency as compared to pendimethalin, but toxicity to the crop was observed when oxyfluorfen was sprayed after 2 days of sowing. Yield and economics were achieved higher with application of 0.75 kg ha-1 of pendimethalin at 2 DAS, which was on par with application of 0.2 kg ha-1 of oxyfluorfen at 1 DAS due to lesser toxicity. Application of 0.75 kg ha-1 of pendimethalin and 0.2 kg ha-1 of oxyfluorfen didn’t leave any herbicide residue after harvest. Hence, application of 0.75 kg ha-1 of pendimethalin at 2 DAS and 0.2 kg ha-1 of oxyfluorfen at 1 DAS can be recommended for effective weed management in irrigated balckgram.

The experiment was conducted to study the effect of salicylic acid (SA) as foliar spray on yield and yield contributing characters of BRRI Hybrid dhan3.The experiment was laid out in a randomized complete block design (RCBD) with three replications and six treatment combinations as, T1: 0 μM SA, T2: 200 μM SA, T3: 400 μM SA, T4: 600 μM SA, T5: 800 μM SA and T6: 1000 μM SA. The results revealed that biomass production, dry matter production and yield and yield contributing characters were significantly increased due to the foliar application of SA. At the maximum tillering (MT) stage, the highest biomass production (15.0 t/ha) and dry matter production was observed in T3 treatment. Treatments T4, T5 and T6 showed significant variation on the effective tillers/hill. The maximum effective tillers/hill were found in the treatment T6. The percentages of spikelet sterility were decreased with increasing the level of SA and the percentage of filled grains/panicle were increased with increasing level of SA. The insect infestation was reduced with increasing level of SA to up to 1000 μM. The maximum grain yield (9.21 t/ha) and straw yield (9.22 t/ha) was found in the treatment T6 which was identical to T5. On the other hand, in all cases the lowest results were found in the control treatment. The result showed that grain yield of rice increased with increasing level of SA to up to 1000 μM (T6 treatment). Our results suggest that foliar spray of SA might be applied to increase the yield of hybrid rice in Bangladesh.Res. Agric., Livest. Fish.4(3): 157-164, December 2017

A field experiment on evaluation of biopesticides against gram pod borer (Helicoverpa armigera Hub.) on pigeon pea was carried out during kharif season of 2012-13. The experiment was laid out in randomized block design with three replications. Gram pod borer is a major pest of pigeon pea in India. For the management of this pest seven biopesticides were tested along with control. Among the biopesticides, Beauveria bassiana @ 1 liter / ha (1x1012 spores/ml) was found to be most effective biopesticide as it recorded lowest larval population (6.68 larvae / 5plants). The highest larval population was recorded in control (12.61 larvae /5 plants). The least effective treatment was Paecilomyces fumosoreseus (9.31 larvae /5 plants). Similar trend was observed in the grain yield as 1667.55 kg/ha, 709.41kg/ha and 1025.21kg/ha , respectively.

Field experiment was conducted during rice fallow season (January-March), 2011 and 2012 to study the effect of DAP application to preceding rice in last irrigation and foliar nutrition to black gram on the productivity and profitability of black gram(ADT 3) under rice fallow condition. The results indicated that application of DAP at 50 kg/ha to preceding rice in last irrigation and foliar spray of DAP (2 per cent) and KCl (1 per cent) at 30 and 45 days after sowing to black gram registered higher plant height (24.6 cm) at 20 DOS number of pods per plant (18.4), grain yield (639 kg/ha), net returns (Rs.22290/ha) and additional income (Rs. 7563/ha). Application of DAP at 50 kg/ha in last irrigation to preceding rice produced significantly higher grain yield of succeeding black gram (613 kg/ha.) over control (488 kg/ha) which was comparable with foliar application of 2 per cent DAP and 1 per cent KCl to black gram. With reference to return per rupee invested, application of DAP at 50 kg/ha to preceding rice in last irrigation registered higher benefit cost ratio of 3.56 in black gram.

The objective of this study was to evaluate the response of irrigation and foliar application of fungicide on the burned grain complex, fungal incidence (Blotter test) and grain yield of two maize hybrids. The experiments were conducted in the agricultural crop 2014/15, in Cruz Alta, RS. For both experiments, the treatments were arranged in a randomized block design and arranged in factorial scheme:2 (commercial hybrids) x 4 (3 fungicides and 1 control), with 4 replicates. In the laboratory, the grains were evaluated, as percentage of burned grains, grain sanity by Blotter test method, weight of one thousand grains and grain yield. There was influence of the use of irrigation, the hybrid, and the application of fungicides on grain yield and the incidence of burned grains and phytopathogenic fungi. Irrigation favored a higher incidence of burned grains and fungi Fusariumsp. and Aspergillussp. The hybrid BG7060HR provided a lower incidence of fungi and burned grains, parallel to a greater mass of a thousand grains and productivity when the fungicide Azoxystrobin + Benzovindiflupir was applied. The application of fungicides in the V8 stage of the culture reduced the incidence of fungi Fusariumsp.and Aspergillussp., especially the fungicide Azoxystrobin + Benzovindiflupir.

Objective of this study was to examine and evaluate the role of different rates of salicylic acid (SA) as foliar spray on growth and yield performance of BRRI dhan29. The experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh from November, 2016 to May, 2017 following a randomized complete block design with five rates of SA in six replications. The results showed that the lower rate of SA (upto 0.75 mM) has a positive effect on rice biomass production including effective tiller per hill, filled grain per panicle, grain yield and straw yield. The highest dry matter production at both maximum tillering and panicle initiation stages was found at SA spray rate of 0.5 mM. The highest number of effective tillers per hill (14.7) as well as the highest filled grain (120.4) and grain yield (8.1 t/ha) were found at SA rate of 0.75 mM. However, the maximum biomass production was obtained at SA rate of 0.25 mM. The minimum grain yield (7.0 t/ha) was observed in the control treatment.

A field experiment was conducted during Kharif 2018 at College Farm, College of Agriculture, PJTSAU to evaluate the effect of various sources of zinc and iron on grain yield, nutrient uptake and grain quality parameters of finger millet. The experiment was laid out in a randomized block design with 14 treatments and replicated thrice.The results revealed that application of different Zinc and iron sources at different rates significantly influenced the grain yield, nutrient (N, P and K) uptake and grain quality parameters (protein and calcium content) of finger millet. Highest grain yield (3653 kg ha-1), protein (11.25%) and calcium content (2.33%) in grain were obtained in the treatment receiving RDF + foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with treatment receiving RDF + foliar application of Fe-humate twice at 30 and 60 DAS (3612 kg ha-1, 10.90% and 2.0%) and the lowest grain yield (1995 kg ha-1), (6.25%) and calcium content (1.10%) were recorded with application of RDF alone. The nutrient uptake (N, P, K and Fe) at all the crop growth stages was significantly higher with the treatment receiving RDF (60:40:30 kg N,P2O5 and K2O kg ha-1) + foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with treatment receiving RDF+ foliar application of Fe-humate twice at 30 and 60 DAS. Highest iron uptake was recorded in treatment receiving RDF+foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with T8, T14 treatments.The highest nutrient uptake of Zinc was obtained in treatment receiving RDF + Zn Humate foliar spray @ 0.25% twice at 30 and 60 days after sowing which was on par with treatment receiving RDF + Zn Humate soil  application. Contrary to the grain yield, nutrient uptake, protein and calcium content there were no significant differences between treatments with respect to Zn, Fe and carbohydrate content in grain.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, to explore the growth and yield performance of boro rice cv. BRRI dhan28 is influenced by foliar spray of potassium nitrate (KNO3) at four rice growth stages. The experiment consisted of four doses of KNO3 viz. 0 (Control), 0.25, 0.50 and 1.00 kg ha−1 and applied at four growth stages of rice development viz. at panicle initiation, at ear emergence, at anthesis period and at dough stage. This experiment was carried out in Randomized Complete Block Design (RCBD) with three replications with 10 m2 (4.0 m × 2.5 m) unit plot size and spacing between blocks and unit plots was 1 m and 0.5 m, respectively. Results revealed that foliar application of potassium nitrate at four growth stages significantly affected yield and yield contributing characters of BRRI dhan28. But most of the yield contributing characters did not differ significantly due to the interaction between potassium nitrate and stage of foliar spray. However, the foliar application of KNO3 @ 0.25 kg ha−1 showed the highest yield production (5.86 kg ha−1) while the lowest yield (4.85 kg ha−1) was found in control. Furthermore, better yield performances were recorded when the KNO3 was applied at panicle initiation stage rather than the other four growth stages. The total number of tillers, 1000–grain weight and grain yield, was higher with foliar spraying of a 0.25 kg ha−1 KNO3 at panicle initiation stage. From this experiment, it may be concluded that foliar application of KNO3 affected the yield performances of BRRI dhan28 and 0.25 kg ha−1 KNO3 produced the highest grain yield when applied at panicle initiation stage of boro rice.
