    CHARACTERIZATION OF RAINFALL FOR CROP PLANNING IN NASHIK DISTRICT OF MAHARASHTRA
    (MPKV,Rahuri, 2018) Inamdar Neha Chhotubhai; Dr. V. B. Gedam
    The daily tahasilwise rainfall data of Nashik district was collected and studied for intra seasonal, yearly, monthly as well as weekly variations and its deviation from normal of corresponding temporal variation. The data revealed that amongst the various tahasils, the annual rainfall ranged between 540.0 to 2992.0 mm. The average annual rainfall was I 084.3 mm. The average annual rainfall for the district was received in 52 days. The seasonal rainfall is much more important for suggesting the cropping pattern. SouthWest monsoon played most imp011ant role in all the tahasils ofNashik district, which is assured rainfall for khar(f crops of different growing periods such as sh011 duration and medium duration crops can be safely grown under rainfed cropping system. However, the good quantum of rainfall received in North-East monsoon season (post-monsoon) can help m proper establishment and early growth of rainfed rabi crops particularly. The summer showers are important from preparatory tillage point of view. There was significant variation in the monthly rainfall variability across the district and the tahasils particularly. The major portion of rainfall concentrated during the months of June, July, August and September. However, a good quantum of rainfall was also recorded in the month of October. During the early months of year i.e. January to May as well as month of November and December a very meager amount of rainfall was recorded in almost all the tahasils. The variation in rainfall fi·om agricultural management point of view is much more important when considered on weekly basis. The study revealed that the monsoon season is very much ideal for agricultural enterprise in the district. The commencement of rainy season in the

    CHARACTERIZATION OF RAINFALL FOR CROP PLANNING IN DHULE DISTRICT OF MAHARASHTRA
    (MPKV,Rahuri, 2018) Kengale Dipali Manohar; Dr. J. D. Jadhav
    The daily tahasilwise rainfall data of Dhule district was collected and studied for intra seasonal, yearly, monthly as well as weekly variations and its deviation from nonnal of corresponding temporal variation. The data revealed that amongst the various tahasils, the annual rainfall ranged between 541.8 to 730.7 mm. The average annual rainfall was 605.1 mm. The average annual rainfall for the district was received in 34 days. The seasonal rainfall is much more important for suggesting the cropping pattern. South-West monsoon played most important role in all the tahasils of Dhule district which is assured rainfall for khar(f'crops of different growing periods such as short duration and medium duration crops can be safely grown under rai!?f'ed condit.ions. However, good quantum of rainfall was received through North-east monsoon (post-monsoon) which help in proper establishment and early growth or rainfed mhi crops particularly. The summer showers are important from preparatory tillage point of view. There was signiticant variation in the monthly rainfall variability across the district and the tahasils particularly. The major p01tion of rainfall concentrated during the months of June, July, August and September. However, a good quantum of rainfall was also recorded in the month of October. During the early months of year i.e. January to May, whereas, in the month of November and December a meager amount of rainfall was recorded in almost all the tahasils. The variation in rainfall from agricultural management point of view is much more important when considered on weekly basis. The study revealed that the monsoon season is very much ideal for agricultural enterprise in the district. The commencement of rainy season in the district on an average was noticed in 22 to 28 MW and persistence of monsoon activities in the following weeks strongly suggested to initiate sowing operation in 22 MW onwards. Sometimes there is break in monsoon activity and vagaries of monsoon has experienced dry spell which adversely affect the crop growth. The analysis showed that the more chance of occ urrence of dry spell at 44 to 45 MW in all tahasils of Dhule district, so care has to be taken that fertilizer application, hoeing and weeding should be avoided.

    SIMULATION OF SOYBEAN GROWTH AND YIELD BY USING DSSAT MODEL UNDER VARIED ENVIRONMENTAL CONDITIONS AT PUNE LOCATION
    (MPKV,Rahuri, 2015) TUPE ARVIND RAMAJI; Dr.D. W. Thawal
    A field investigation entitled "Simulation of soybean growth and yield by using DSSA T model under varied environmental conditions at Pune location" was conducted in 'D' division of Agronomy Farm, on the experimental field of Department of Agricultural Meteorology, College of Agriculture, Pune-5 during khar(f seasons of 2012 and 2013. Four sowing times I FN of June (S 1) , II FN of June (S2) , 1 FN of July (S3) and II FN of July (S4) to create different set of environmental conditions for weather variability and tlu·ee varieties JS-335 (V1) , MACS-450 (V2) and DS-228 (V3) were laid out in Split Plot Design (SPD) with four replications.The soybean crop was sown in I FN of June (S 1) accumulated higher Growing Degree Days (GOD) and significantly higher biomass and seed yield with maximum heat use efficiency. Subsequent, sowings beyond II FN of June (S2) , I FN of July (S3) and II FN of July (S4) during 2012 and 2013 encountered higher amount of heat use efficiency and rainfall during vegetative and flowering stage and decreasing trend of heat use efficiency and rainfall across the critical reproductive stage of seed formation to development which consequently resulted in lower seed yield. Soybean variety, DS-228 (V 3) recorded significantly higher seed yield with maximum heat use efficiency. Subsequent, delay in sowing during II FN of July (S4) resulted in shortening of the crop growth period and decrease of plant height, dry matter accumulation, leaf area index, yield attributes and harvest index. The growth and yield parameters were recorded the highest in early sown crop I FN of June (S 1), followed by II FN of June (S2), I FN of July (S3) and the lowest in II FN of July (S4) sowing during both years of study. The climatic factors viz., maximum and minimum temperature (0C), morning and everting relative humidity(%), rainfall (mm) and number of rainy days, wind speed (km hr- 1 ), evaporation rate (mm day" 1 ) and bright sunshine (hrs) were played vital role in occurrence and development of pest like semilooper, girdle beetle and spodoptera on soybean crop. These climatic factors are highly correlated either positively or negatively with the occurrence and development of semilooper, girdle beetle and spodoptera on soybean crop. Crop simulation model (CROPGRO-soybean, DSSAT v 4.5) performance in respect of phenological phases viz., anthesis day, first pod day, first seed day, physiological maturity, plant height, leaf area index, seeds per pod, seeds per square meter, threshing percentage and harvest index was found to be highly reliable. The model predicted the reliable seed yield in varieties DS-228 (V3) and MACS-450 (V2) during 2013. But the seed yield was slightly overestimated in varieties viz., JS-335 (V1) and MACS-450 (V2) during both

    RELATIONSHIP BETWEEN WEATHER PARAMETERS AND INCIDENCE OF MITES, THRIPS ON ROSE AND THEIR MANAGEMENT UNDER POLYHOUSE CONDITIONS
    (MPKV,Rahuri, 2014) Deshmukh Anuuta Prashant; S.B.Kharbade
    The research experiment on, "Relationship between weather parameters and incidence of mites, thrips on rose and their management under polyhouse conditions" was carried out during 2013 at Hi-Tech. Floriculture and Vegetable Project, College of Agriculture, Pune. The newer chemical pesticide molecules along with biopesticides viz:Acetamiprid (TJ), Spinosad (T2),Thiamethoxam (T3 ), Clothianidin (T4), Chlorfenapyr (Ts), Hexythiazox (T6), Abamectin (T7),M.anisopliae (Ts),M-Impact (T9), Neem oil (T10) were evaluated against mites and thrips on rose under poly house conditons. The treatments with Chlorfenapyr, Abamectin and Clothianidin were found to be most effective against mites by recording m~an population of 2.65, 3.76 and 4.47 mites/three leaves, respectively. The next best treatments in descending order of their efficacy were Thiamethoxam > Hexythiazox> Acetamiprid and Spinosad. This was followed by the treatments with biopestcides, M-Impact, Neem oil and M anisopliae. For the management of thrips infesting rose leaves and buds, the treatments with Spinosad and Clothianidin were observed to be most promising by recording lowest incidence. The next best treatments in descending order of their efficacy were Chlorfenapyr > Thiamethoxam > Hexythiazox > Acetamiprid > Abamectin. This was followed by biopesticide treatments M- Impact, Neem oil, M. anisopliae. Weekly mean incident radiation (PAR) of 350.37 ~unolm-2 s- 1 was recorded with different pesticide treatments under polyhouse conditions as against 1040.13 f.Unolm-2s-1 in open field condition. The lowest weekly mean canopy reflected radiation (13.58 f.1molm- 2s-1) was observed with spraying of Spinosad 45% SC @0.3 ml/1 (T2) under polyhouse conditions. Lowest weekly mean transmitted radiation of 168.56 f.1molm-2s-1 was recorded in a treatment with spraying of Spinosad 45%SC@ 0.3mlll(T2) followed by treatment of Clothianidin 50%WDG @ 0.2g/l (T4) (l70.49f.1molm-2s-1). The pesticide treatments recorded lower transmitted radiation due to denser canopy and lower incidence of mites and thrips. The highest absorbed radiation was found in the treatment with spraying ofSpinosad 45%EC@ 0.3ml/l (T2) (17l.llf.1molm-2s-1)_The light

    "EFFECT OF WEATHER PARAMETERS ON THE INCIDENCE ' . ... .~ \ :.... .. . •. ' . OF SORGHUM SHOOT FLY'(Athertgona soccata Rondani) UNDER DIFFERENT SOWING DATES"
    (MPKV,Rahuri, 2012) Chakane Sunanda Rajaram; S.B.Kharbade
    The research experiment on "Effect of weather parameters on the incidence of sorghum shoot Fly (Atherigona soccata Rondani) under different sowing dates" was undertaken during kharif 20 ll season, at . Agril. Meteorology Department Farm, College of Agriculture, Pune. The experiment was laid out in a Randomized Block Design with five treatments and four replications. Sorghum crop was sown at five different dates viz.; June 2Yd (25th MW), July 1st (26111 MW), July gth (27thMW), July 15th (28th MW) and July 22"d (29th MW). The gross and net plot sizes were 4.95 m X 3.60 m and 4.05 m X 3.00 m, respectively. The incidence of shoot fly on sorghum infestation in kharif season increased as sewings were delayed from onset of monsoon season. Initial sowing date of 23rd June (25th MW) was observed to be the most suitable sowing date in kharif season for hybrid sorghum CSH-9 cultivar since the crop suffers less from the infestation of shoot Fly because of conditions. The increase in egg laying was observed as the sowing dates were delayed except, sowing date treatment of 15th July (S4). The lowest total egg count of 22.7 was observed in initial treatment of 23rd June sowing (S 1). This was followed by sowing treatments of 1st July (S2) and gth July (S3) in which total egg count of 25.5 and 33.2 was recorded,respectively. However, the sowing treatment of 15th July (S4) recorded 31.5 eggs/ 10 plants. The highest total egg count of 39.5 eggs/ 10 plants was observed in sowing treatment of22"d July (S5). The initial treatment 23rd June sowing (SI) recorded lowest of 84 total dead hearts/ plot. The treatment with 1st July (S 2) sowing recorded 101 total dead hearts per plot. This was followed by the treatments with gth July (S3) and 15th July (S4) in which 113 and I 51 dead hearts per plot were noticed. The highest of 203 total dead hearts/ plot were recorded in a treatment with 22"d July sowing (S5). On per cent basis the treatment with 23rd June (S 1) sowing was found to be most suitable which recorded lowest of 33.6 per cent dead hearts. This was followed by the treatments with I 51 July (S2), 8111 July (S3), 151 h July (S4) in which 40.4, 45.2, 60.4 per cent dead hearts were noticed, respectively. The highest percentage of dead hearts (81.2) was recorded in delayed sowing treatment of 22"d July (Ss).
