RESUMEN
A field experiment was conducted during rabi season of 2022 at Karunya Institute of Technology and Sciences, Coimbatore to study the performance of different pearl millet-based intercropping with legumes under rainfed condition. Greengram (Vigna radiata), cowpea (Vigna unguiculata) and redgram (Cajanus Cajan) were sown as intercrops in replacement series of 4:1 and 6:1 row ratio. The result of the study indicated that intercropping of blackgram and redgram with pearl millet in 4:1 gave higher total grain yield (25503.0 kg/ha) and stover yield (4927.1 kg/ha) compared to the sole cropping of pearl millet under rainfed condition. Other intercropping indices like grain equivalent yield, land equivalent ratio, relative crowding coefficient, competition index and income equivalent ratio were calculated. Intercropping system of pearl millet + blackgram (4:1) recorded the higher net returns (Rs. 81,621/ha) and B:C ratio (2.42).
RESUMEN
The Field experiments were conducted to evaluate the effect of cropping systems and nutrient management practices on the yield, and economics of pearl millet in the School of Agricultural Science, Karunya Institute of Technology and Sciences, Coimbatore, India). The experiments were laid out in Factorial Randomized Block Design (FRBD) with two factors (Cropping system and Nutrient management) and three replications for two consecutive seasons in 2022-23. The study comprised three cropping system treatments namely C1 – Sole Pearl millet cropping, C2 - Pearl millet + Black gram intercropping (1:1), C3 – Pearl millet + Cowpea intercropping (1:1) along with four nutrient management treatments viz., N1 - 100% Recommended dose of fertilizer (RDF) @80:40:40 kg of N, P2O5, and K2O/ha., N2– 75% RDF + Azospirillum @2kg/ha and Phosphate solubilizing bacteria (PSB) @2kg/ha, N3 – 75% RDF + Soil application of Azospirillum (2kg/ha) and PSB (2kg/ha) + Foliar spray of 2% urea @ 15 and 35 days after transplanting (DAT), N4 – 75% RDF + Soil application of Azospirillum (2kg/ha) and PSB (2kg/ha) + Foliar spray of Panchagavya3% @ 15 and 35 DAT. The results of the experiment revealed that the intercropping of black gram or cowpea in pearl millet proves to be beneficial and advantageous in terms of, grain yield and returns per rupee invested, rather than going for the sole cropping of pearl millet. On the other hand, reduced application of inorganic recommended dose of fertilizers by 25% with the inclusion of biofertilizers like Azospirillum and phosphate solubilizing bacteria, along with the foliar application of 2% urea or 3% Panchagavya will be an economically viable and environmentally sustainable nutrient management practice for improving the yield of pearl millet.
RESUMEN
A field experiment was conducted in rabi seasons (2022) at Karunya Institute of Technology and Sciences, Coimbatore to study the maize-based intercropping with different legumes under rainfed condition as there are less research work regarding intercropping of maize in this area. Greengram (Vigna radiata), cowpea (Vigna unguiculata) and horsegram (Macrotyloma uniflorum) were selected as intercrops in 4:1 and 6:1 row ratio. The result of the study indicated that intercropping of greengram and cowpea with maize (Zea mays L.) in 4:1 gave higher total grain yield and stover yield compared to the sole cropping of maize under rainfed condition. Other intercropping indices like grain equivalent yield, land equivalent ratio, relative crowding coefficient, competition index and income equivalent ratio were calculated. Intercropping system of maize + greengram (4:1) recorded the higher net return and B: C ratio followed by it maize+ cowpea (4:1). Therefore, under rainfed conditions of western zone of Tamil Nadu, maize + greengram 4:1 intercropping system may be suggested to get greater net return and B: C ratio.
RESUMEN
A field experiment with the objectives to understand the evaluation of mulching effects on weed control in blackgram production under irrigated condition involving two factors viz., mulching (paddy straw mulching, sugarcane trash mulching, no mulching) and herbicidal treatments (pendimethalin pre-emergence (PE) @ 1.0 Kg/ha, pendimathalin + Imazethapyr (pre-mix) pre-emergence Valor 32% EC 1.0 Kg/ha, Hand weeding on 15 and 30 days after sowing, weedy check) was undertaken in Factorial Randomized Block Design (FRBD) design with three replications at the instructional farm of Karunya Institute of Technology and Sciences, Coimbatore region of western Tamil Nadu during the cropping seasons of Rabi 2022-23. Results revealed that paddy straw mulching sequential application of Pendimathalin + Imazethapyr (pre-mix) pre-emergence Valor 32% EC and sugarcane trash mulching sequential application of pendimathalin + imazethapyr (pre-mix) pre-emergence Valor 32% EC recorded lower weed density, weed dry weight and maximum crop yield as well as net returns over rest of the mulching and herbicidal treatments.
RESUMEN
Autoimmune hemolytic anemia (AIHA) secondary to hematological malignancy is well-known and common in the elderly. AIHA associated with infection is less commonly reported in the elderly. We are reporting a case of AIHA in an elderly female with comorbidities, probably secondary to Gram-negative infection. The case was admitted and treated during the peak of the second wave of the COVID pandemic. The treatment of AIHA also had an impact on the progress and outcome of the underlying disease, leading to readmission in a short span of time. The patient also developed a thrombotic complication known to be associated with AIHA.
