    ESTIMATION OF SURFACE ENERGY FLUXES OVER MUSTARD CROP USING TWO SOURCE ENERGY BALANCE MODEL
    (DEPARTMENT OF AGRICULTURAL METEOROLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2020) Vala Radhika P.; Dr. M. M. Lunagaria
    The present investigation entitled “Estimation of surface energy fluxes over mustard crop using two source energy balance model” was laid out in research farm near Agrometeorological observatory, B. A. College of Agriculture, AAU, Anand (Gujarat), India during 2019-2020. The soil of the experiment field was loamy sand. The objectives were to parameterize of two source energy balance model for mustard crop, estimation of surface energy fluxes over mustard crop and validation of TSEB-2T model. The treatment combinations consisting of four levels of sowing dates in a main plot and three varieties of mustard in a sub-plot were tested under split plot design with four replication. Three cultivars namely, Bio 902, GM 3 and GDM 4 were sown on 10th October, 20th October, 30th October and 10th November. Periodical plant biometric observations and micrometeorological observations were taken from each plot of a single replication at weekly and every alternate day respectively.

    STUDY OF ASTRO-METEOROLOGICAL TECHNIQUES FOR PREDICTING RAINFALL AND ITS DISTRIBUTION IN GUJARAT
    (DEPARTMENT OF AGRICULTURAL METEOROLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2020) Vaidya Vidyadhar Bhaskar; Dr. Vyas Pandey
    The study on “Astro-meteorological techniques for predicting rainfall and its distribution in Gujarat” was conducted with an aim to conglomerate the ancient knowledge of astronomy with present day weather forecast and develop relationship between astrological/astronomical parameters with actual rainfall received over the period of time. The study was conducted with the objectives (i) finding out predominant planetary combinations, (ii) classifying and establishing relationship between planetary combinations and start of rainy season, wet spells, extreme rainfall and withdrawal of monsoon and (iii) forecasting and validation of Varahmihir’s Model of seasonal rainfall prediction for 16 locations of Gujarat. Validation of predominant planetary combination model using 35 years data for onset of monsoon, withdrawal of monsoon, wet spell and extreme rainfall at different locations of Gujarat was carried out in independent data (2015-2018).

    MOISTURE STRESS DETECTION IN CHICKPEA (Cicer arietinum L.) BASED ON CANOPY – AIR TEMPERATURE DIFFERENTIAL USING INFRARED THERMOMETER
    (DEPARTMENT OF AGRICULTURAL METEOROLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2020) Sabhani Khyati H.; Dr. B. I. Karande
    The present investigation entitled “Moisture stress detection in chickpea (Cicer arietinum L.) based on canopy – air temperature differential using infrared thermometer” was laid out on the Agronomy farm, B. A. College of Agriculture, AAU, Anand (Gujarat), India during rabi season of the year 2019-2020. The soil of the experiment field was loamy sand. The objectives were to determine the crop water stress index (CWSI) for chickpea crop and explore association of stress indices with crop soil moisture regimes, yield and yield attributes and to determine optimum irrigation scheduling under IW:CPE ratio and FYM interaction. The treatment combinations consisting of three irrigation levels in a main plot and two FYM levels in a sub-plot were tested under split plot design with four replication. Three irrigation levels include 0.4 IW:CPE ratio, 0.6 IW:CPE ratio and 0.8 IW:CPE ratio and two FYM levels include no FYM and 10 t ha-1 FYM application. Agrometeorological observations were taken from each plot of a single replication at every alternate day. Periodical crop observations were taken from each plot of a single replication at every 15 days interval starting from 20 days after sowing. Post harvest observations were taken from each plot at harvesting.

    EVALUATION OF AQUACROP MODEL FOR SIMULATION OF YIELD RESPONSE TO WATER IN RAINFED GROUNDNUT
    (DEPARTMENT OF AGRICULTURAL METEOROLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2020) Joshi Sanjaybhai; Dr. M. M. Lunagaria
    An experiment was conducted at Agronomy farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during kharif-2018. The experiment was laid out in a randomized block design (factorial) with four treatments in six replications. It was carried out with combination of two dates of sowing and two varieties. The prime objective of the field experiment was to evaluate and validate the AquaCrop model for groundnut. Discussion of the results of the field experiment and statistical analysis of the experimental data was complete in itself for agronomic purpose.

    DETERMINATION OF INFRARED THERMOMETRY BASED INDICES FOR CROP WATER STATUS MONITORING IN RAINFED PEARL MILLET
    (DEPARTMENT OF AGRICULTURAL METEOROLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2019) RATIYA PUJA BHIMABHAI; Dr. M. M. Lunagaria
    A field experiment was conducted during kharif season of 2018 at Agronomy farm, near Agrometeorological observatory, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat), India to study infrared thermometry-based indices for crop water status monitoring in rainfed pearl millet. The soil of the experimental field was loamy sand in texture. The experiment was laid out in split plot design with four replications. The nine treatments composed of three dates of sowing and three cultivars were studied. Three cultivars namely, GHB 538, GHB 558 and GHB 744 were sown at onset of monsoon, after 10 days of onset of monsoon and after 20 days of onset of monsoon.

    MICROCLIMATE IN PEARL MILLET CROP UNDER DIFFERENT PLANTING GEOMETRIES
    (DEPARTMENT OF AGRICULTURAL METEOROLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2019) Harshkumar R. Pandya; Dr. M. M. Lunagaria
    A field experiment was conducted during kharif season of 2018 at Agronomy farm, near Agrometeorological observatory, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat to study microclimate in pearl millet crop under different planting geometries. The experiment was laid out in a randomized complete block design with six replications and four treatments. Photosynthetically active radiation (PAR) was measured using a Line quantum sensor (Li-Cor Inc., USA). Vertical PAR profile was measured weekly by positioning the sensor 2 cm, 40 cm, 80 cm, 120 cm heights during 1220 h to 1300 h. Daytime PAR pattern was observed fortnightly by measurements at 800 h, 1100 h, 1400 h and at 1700 h. Air temperature and relative humidity were measured using Assaman psychrometer. They were measured at 2 cm, 40 cm, 80 cm, 120 cm heights during 1220 h to 1300h. Daytime air temperature and humidity patterns were measured fortnightly at 800 h, 1100 h, 1400 h and 1700 h.
