Legume Research, 2026
Rainfed deep Vertisols in semi-arid regions of India are traditionally left fallow during the kharif season to conserve soil moisture for rabi crops, particularly chickpea (Cicer arietinum L.). While this practice ensures residual moisture availability, it significantly limits cropping intensity, land productivity and resource use efficiency. Recent agronomic research has demonstrated the feasibility of cropping kharif fallows with short-duration, low-water-demand crops such as green gram, foxtail millet, sesame and cowpea. These crops can be harvested before the onset of rabi season, leaving sufficient residual moisture for chickpea establishment. Moreover, strategic interventions in land configuration, nutrient management and integrated pest control have enabled successful kharif cropping in Vertisols, mitigating risks associated with waterlogging and poor soil aeration. This review synthesizes multidisciplinary research on kharif crop-chickpea systems, comparing them with conventional fallow-chickpea rotations across agronomic, economic and ecological metrics. Evidence from long-term trials and farmer participatory research reveals that intensified systems improve chickpea equivalent yields, enhance soil carbon sequestration, suppress pest and disease cycles and contribute to climate resilience. Integrated nutrient and residue management further supports soil health and microbial activity, while diversified cropping systems offer better profitability and livelihood security. Across Vertisol regions, inclusion of kharif crops increased chickpea equivalent yield by 22-33% and soil organic carbon by 18-21% compared with traditional fallow-chickpea system, while also improving yield stability and farm profitability. The paper also identifies key research gaps and policy interventions needed to scale sustainable kharif cropping in Vertisol landscapes. By integrating agronomic innovations with ecological and socioeconomic perspectives, this review provides a comprehensive framework for advancing chickpea-based systems and promoting sustainable intensification in rainfed agriculture. - Indigenous technical knowledge on drought mitigation techniques on yield of groundnut and adoption of farmers in semi-arid regions of Andhra Pradesh

Indian Journal of Agricultural Research, 2025
Background: Cluster Front Line Demonstrations were conducted to study the comparative performance of new chickpea varieties in the western parts of Kurnool district, Andhra Pradesh. These demonstrations were conducted at twenty five locations during the Rabi season of two consecutive years (2019-20 and 2020-21). Methods: Three improved chickpea varieties (Nandyal Gram-3, Nandyal Gram-49 and Nandyal Gram-452) were selected to implement these demonstrations and the improved varieties were compared with the locally grown JG-11 variety. Result: During two years of assessment, the pooled results revealed that the highest mean number of pods (51.3) per plant and average pod yield (2234 kg ha-1) were recorded in Nandyal Gram-452 compared to local variety JG-11 (41.2 pods per plant; 1862 kg ha-1). The lowest incidence of fusarium wilt was recorded in Nandyal Gram 452 (6.14%) followed by Nandyal Gram 49 (9.73%) and Nandyal Gram 3 (12.04%) compared to JG-11 (15.83%). The lowest dry root rot was also observed with Nandyal Gram-452 variety (10.92%) compared to JG-11 (18.19%). The higher average net income (80486 Rs ha-1) and benefit cost ratio (2.9) were realized in the demonstration with the improved Nandyal Gram-452 variety in comparison to lower net income (58370Rs ha-1) and benefit cost ratio (2.3) with JG-11. These results clearly indicated that the improved chickpea variety Nandyal Gram 452 is the best alternative old variety JG-11 which is being cultivated since 2005. - Survey and Molecular Identification of Begomovirus Associated with Chilli Leaf Curl Disease in Kurnool District of Andhra Pradesh

Background: Chilli is an important spice and vegetable crop grown in tropical and sub-tropical climate. Recently, Chilli leaf curl disease has become a serious threat to chilli growing farmers. Methods: The present study was aimed to know prevalence of leaf curl disease in chilli. For this, roving field survey was carried out in 63 randomly selected chilli fields covering 21 villages in seven mandals of Kurnool district in Andhra Pradesh during 2019-20. Attempts were also made on molecular diagnosis of begomovirus associated with chilli leaf curl disease. Result: The average mean per cent incidence of chilli leaf curl virus in Kurnool district was 50.76% ranging from 25.0% to 82.2%. During the field survey, the highest mean leaf curl incidence was noticed in Peddakadubur mandal (71.1%) followed by Gonegandla (59.96%) and Nandavaram (52.27%) mandals, while the lowest leaf curl incidence was observed at Adoni (37.83%) mandal in Kurnool district. The amplified coat protein gene was sequenced and obtained 770bp sequence which was deposited in Gen Bank. The obtained sequence shared maximum identity of 99.7% with chilli leaf curl virus Guntur isolate (MN417112). As per species demarcation and nomenclature criteria of begomovirus, the virus associated with chilli leaf curl disease in Kurnool district shared greater than 94% sequence identity with Chilli leaf curl virus. Hence it was identified as chilli leaf curl virus (ChiLCV). - On Farm Testing on Foliar Application of Nutrients and Growth Regulators in Pigeonpea (Cajanus cajan L.)

Background: Onfarm Testings were conducted to asses effect of TNAU Pulse wonder in pigeonpea variety LRG-52 in ten farmer’s holdings of kurnool district during kharif from 2018-19 to 2020-21. Methods: The experiment consisted of 7 technology options (treatments). T1: consisting recommended dose of fertilizers along with spraying of pulse wonder @ 5 kg ha-1 during flowering and 15 days after 1st spray, T2: 75% RDF + Pulse wonder @ 5 kg ha-1 at flowering, T3: 50% RDF + Pulse wonder 5 kg ha-1 at flowering,T4: 100% RDF+ 2% DAP at flowering and pod formation stage T5: 100% RDF alone (20:50: 0 NPK kg ha-1),T6: Farmers practice ( 30: 60: 10 NPK kg ha-1 ),T7: Control. Data was analyzed using least significant difference in R software. Result: The results revealed that the T1 recorded the highest plant height (130,129,127 cm at flowering stage in 2018-19, 2019-20 and 2020-21 respectively). The lowest flower shedding observed in T1 treatment while it was the highest under T6 in all the three years of the study. Pod yield was the highest in T1 (1889, 1870 and ,1873 kg ha-1 in 2018-19, 2019-2020 and 2020-21 respectively) and the lowest in T7. The average highest benefit cost ratio (4.0) was realized in T1 and lowest in farmers practice (T6). Seed yield was positively correlated with number of flowers plant -1 (r value 0.813, 0.762 and 0.735) and test weight (r value 0.795,0.8 and 0.754) and negatively correlated with flower shedding ( r value -0.788,-0.712 and -0.750) in 2018-19, 2019-20 and 2020-21 years respectively. The final yield of crop is the cumulative effects of growth and yield attributes which manipulate the favorable parameters for higher yields. - Construction of Full-length Dimer Clones of Yellow Mosaic Virus and Screening of Blackgram Germplasm using Agroinoculation

Legume Research, 2023
Background: Vigna mungo (Blackgram) is the major pulse crop cultivated in the Indian sub-continent. It is highly prone to yellow mosaic disease (YMD), which is widespread problem because all cultivated varieties are susceptible to the YMD in Andhra Pradesh state. The presence of two species of begomovirus i.e. Mungbean yellow mosaic virus (MYMV) and Mungbean yellow mosaic India virus (MYMIV) with YMD was reported in Andhra Pradesh. The current study was aimed to develop simple method of viral dimer clone construction and identifying the resistant blackgram genotypes against two species of begomovirus (MYMV and MYMIV) by agroinoculation technique. Methods: In this study, we standardize the rolling circle amplification (RCA) based viral dimer clone construction (MYMV DNA-A, MYMV DNA-B and MYMIV DNA-A) and constructed viral dimer clones were used to transform Agrobacterium tumefaciens EHA105 cells through freeze-thaw technique. Sprouted seed method of agroinoculation screening was conducted. Result: Total 45 blackgram genotypes were screened by sprouted seed method of agroinoculation with two combinations of viral dimeric constructs (MYMV-TPT-A+MYMV-TPT-B and MYMIV-TPT-A+MYMV-TPT-B). Twenty four genotypes offered resistant against MYMV infection and twenty three genotypes were resistant to MYMIV infection. Total 17 genotypes offered resistance to both species of virus (MYMV andMYMIV) associated with YMD. - Genetic Variability Studies of Yellow Mosaic Virus Infecting Blackgram [Vigna mungo (L.)

Legume Research, 2022
Background: The productivity of blackgram is affected by many biotic and abiotic stresses. Among the biotic stresses, yellow mosaic disease (YMD) cause severe yield loss and it is caused by four distinct viruses (belongs to genus begomovirus) collectively known as yellow mosaic virus (YMV). Hence there is need to characterize various YMV isolates associated with blackgram in Andhra Pradesh. Methods: YMV infected blackgram samples were collected from East Godavari, Kurnool and Prakasam districts of Andhra Pradesh. The Rolling Circle Amplification (RCA) based full length MYMIV DNA-A and MYMV DNA-B of three isolates were cloned and sequenced. Result: Nucleotide sequence of full length DNA-A of MYMIV-East Godavari isolate showed greater than 96% similarity at nucleotide and greater than 90% at amino acid level with other MYMIV isolates in NCBI database. The complete DNA-A nucleotide sequence of MYMIV-Kurnool and MYMIV-Prakasam isolates shared greater than 99% similarity at nucleotide and greater than 98% at amino acid level with other MYMIV isolates. The complete nucleotide sequence of MYMV DNA-B of three isolates (East Godavari, Kurnool and Prakasam) had greater than 97% homology with other MYMV DNA-B isolates from database. The predicted amino acid sequence of MYMV DNA-B of three isolates shared greater than 96% homology with other MYMV-B isolates. The common region (CR) sequence similarity between MYMIV-As and MYMV-Bs of East Godavari and Kurnool isolates was 76.4% and 78.3% with Prakasam isolate. The divergence between the MYMIV-A and MYMV-B of present three isolates (East Godavari, Kurnool and Prakasam) under study were ranged from 22.2 to 22.6%. - On farm testing of rice variety ndlr-7 as an alternative to traditionally grown bpt-5204 in kurnool district of Andhra Pradesh

Agricultural Science Digest, 2020
Back Ground: Rice (Oryza Sativa L.) is major crop in Andhra Pradesh being cultivated in 22.11 lakh ha average productivity of 3350Kg/ha Local BPT-5204 (samba mashuri) is high susceptibility to blast, sheath blight and gall midge. Since this is consumers’ preference both in the rural and urban markets, farmers are cultivating BPT-5204 though this variety is susceptibility to blast and BPH leads to high cost of cultivation .As an alternative to this NDLR-7 variety developed by Regional Agricultural Research Station (RARS), Nandyal, ANGRAU NDLR-7 was tolerant to blast, BPH, sheath blight, leaf folders and gall midge. Methods: NDLR-7 was introduced by KVK, Banavasi through on farm trail during 2016-17 and this trial was continued for three years as an alternative to traditionally grown BPT-5204. Result: The data from the three years of on farm trail reveals that the cost of cultivation has drastically reduced from Rs. 66050/ha to 50,538/ha due to reduced use of pesticides. The yield in demonstration plot (NDLR-7) was 7437.5 Kg/ha compared to control (5812 Kg/ha).
