Diversity interrelationships among capsicum spp. and forms and developement of papricas
(Department of Olericulture, College of Horticulture, Vellanikkara, 1994) Indira, P; Peter, K V
Capsicum, a new world genus, has richness in diversity that has not yet received the needed attention. The cultivated chilli varieties offer many problems in classification because of their great number, the transitory nature and creation of new ones through hybridization and selection processes. The present studies on “Diversity inter relationships among Capsicum spp. And forms and development of paprikas” were conducted at the College of Horticulture, Vellanikkara. The main objectives were grouping of chilli genotypes biometrically and biochemically and development of paprikas. For biometrical grouping chilli genotypes belonging to four cultivated species of Capsicum were evaluated during two seasons (August, 1991- January, 1992 and May, 1992- September, 1992). They were clustered into different groups based on D2 values. There were 9 clusters during first season and 6 clusters during second season. The distribution of genotypes into clusters showed no regularity. The isozyme patterns of two enzymes viz.peroidase and esterase were studied in the three cultivated species of Capsicum and also for the nine biometrical groups. Among the different plant parts studied roots showed clear bands in case of peroxidase and mature leaves were the best sampling tissue for esterase enzyme. There were species specific bands in all the three species. The nine biometrical groups showed variation for banding pattern in case of peroxidase and esterase. There were some common bands for both the enzymes. Twenty paprika genotypes were collected from different sources and their morphological descriptions were made as per IBPGR descriptor. Field evaluation was done for two seasons (October –March, 1991; May – October, 1992). There was significant difference among genotypes for the different characters studied. There was much seasonal variation also. CA 517 recorded minimum incidence of bacterial wilt during both seasons under the field conditions. CA 582 showed highest colour value but CA 604 and CA 605 recorded minimum pungency.

Impact of deposit mobilisation campaign on the agricultural advances of the primary agricultural credit societies
(College of Co-operation and Banking, Mannuthy, 1988) Indira, P; Mohandas, M
The study on the Impact o f the Deposit Mobilisation Campaign on the agricultural advances o f the Primary Agricultural Credit Societies has been carried out to examine the extent end pattern of deposits mobilised and its impact on their resource base as well as their agricultural advances. Fourteen societies consisting of ten per cent of the PaCS in Trichur district were selected at random for detailed study. It was seen that no scientific criteria like the past performance o f the societies or the savings potential of the area were considered while fixing the targets. Percentage analysis and paired t-test revealed that there was significant increase in deposits in four years when the DMC was held during April-May While it was not significant in two years 1982-83 end 1983-84 When the DMC was held during November-January. There was also qualitative improvement in the composition of deposits. During the normal period, fixed deposits occupied only below 19 per cent of the deposits but during the DMC it ranged between 23 per cent and 29 per cent. A correlation test between the correlation coefficients of deposits and withdrawals during the normal period and with one month lag revealed that it was significant in 1983-84 and 1984-85 indicating concurrent withdrawal of deposits. But in 1985-86, i t was significant with one month lag. Alternative concepts o f Credit Deposit Ratios (CDR - estimated as the ratio of advances to deposits) were used to analyse the lending pattern. Cross CDR ranged between 13.87 and 42.86 during the DKC while it was high during the normal period 1 ranging between 88.97 and 120.01. But it showed an increasing trend with three months lag except in 1982-83 and 1983-84. Gold loans occupying below 57 per cent o f the total loans during the normal period was above 57 per cent during the DMC in five years. But Agricultural Loans were getting an increased share with a lag o f two months. DKCs during the period o f April-May had resulted in significant increase in incremental and to ta l deposits and comparatively higher CDR but those held during the months of November-December and Dec amber-January did not show any significant increase in deposits and had a lower CDR. it was thus observed that the period o f the EMC has an important effect on the success o f the EMC.

Performance of capsicum under rainshelter
(Department of Olericulture, College of Horticulture, Vellanikkara, 2003) Vezhavendan, S; Indira, P
An experiment was carried out in the Department of Olericulture, College of Horticulture, Vellanikkara, during the rabi (2001) and kharif (2002) seasons to study the performance of capsicum under rain shelter. The experiment was laid out in Completely Randomised Block Design with four replications. Four Capsicum varieties, viz. CA 776, Yolo Wonder, California Wonder, CA 567 and one Fl hybrid Pusa Deepthi were used for the study. The study revealed that the crops grown under rain shelter performed better with respect to all the characters viz. Plant height, 'number of branches, early flowering, early harvest, number of fruits per plant, fruit size, fruit yield per plant, number of seeds per fruit and number of harvests. As like the growing condition, the season also influenced some attributes. Rabi season crop gave better results regarding number of fruits per plant, fruit .yield per plant, number of seeds per fruit, fruit size and number of harvests. Where as kharif crop produced tall plants with larger fruit size. Though tlte variety CA567 gave more yield consistently during both the seasons, the yield was higher under rain shelter condition. CA 776 (CA 776) performed well during rabi but its performance was poor during kharif due to the severe incidence of pest and diseases. Even though the weather parameters like temperature, humidity and light intensity not influenced individually and significantly but Lad cumulative effect, which is evident from the performance of the crop under rain shelter condition. The severe incidence of pest like mite caused reduction in the yield during kharif season under rain shelter. The B/C ratio obtained from rain shelter crop was !: 0.51 and 1: 0.15 for open field crop. 75 per cent of total cost of cultivation was incurred labour charge. If we are utilizing the family labour, it not only provides better profit but also create chances of self-employment for the literate, unemployed youth of Kerala .

(Department Of Olericulture, College Of Horticulture, Vellanikkara, 2007) Margaret Thomas; Indira, P
Investigation on physiological attributes of yield in tomato was carried out at Department of Olericulture, College of Horticulture, Vellanikkara, Thrissur during October 2005 to February 2006 under two different growing conditions (polyhouse and open field). The experiment was laid out in Randomised Complete Block Design with four replications. Indeterminate LE 643 and semideterminate Anagha were the varieties used for the study. The study revealed that crop raised in polyhouse showed more plant height (upto 30 DAT) and internodal length. Number of branches was higher in open field. Relative Growth Rate and Net Assimilation Rate were higher in open field compared to polyhouse at initial stages but at later stages, reverse situation was noticed. Crop growth Rate and LAI were maximum in polyhouse condition. Number of inflorescences and fruits per plant, number of harvests per plant, single fruit weight and fruit yield per plant were observed higher in polyhouse. Maximum temperature and RH at morning had positive significant correlation with vegetative characters and number of inflorescences irrespective of growing condition. Maximum temperature and light intensity had significant correlation with days to flower. Rainfall showed negative correlation with plant characters. Canonical correlation revealed that crop characters were more related to the weather parameters under polyhouse condition. Significant partial correlation was noticed between crop yield and maximum and minimum temperature in polyhouse. Relative humidity at morning and light intensity had variety specific correlation with yield. Pests and diseases incidence was comparatively higher in polyhouse condition due to higher temperature but cracking percentage was higher in open field. The fruit appearance and quality were comparatively better in polyhouse condition.

(Department of Olericulture, College of Horticulture, Vellanikkara, 2013) Ambily Sadanandan; Indira, P
The present study entitled “Productivity of cucumber (Cucumis sativus L.) as influenced by seasons and growing systems” was undertaken in the Department of Olericulture, College of Horticulture, Vellanikkara during 2009. The objectives of the study were to investigate the feasibility of off season production of cucumber in rain shelter, to identify ideal variety for protected cultivation and to study the comparative performance of crops in rain shelter and open field. The experiment was laid out in a randomized block design with three replications inside the rain shelter and open field. Three varieties Poinsette, AAUC-2 and Kuruppamthara Local were used for the study during summer season (February to April) and rainy season (June to August). Protected condition was provided using a rain shelter of 100m2 floor area. Observations on vegetative and reproductive characters were recorded during the course of investigation. The daily weather parameters were recorded inside and outside the rain shelter. During summer season, rain shelter crop had maximum vine length than open field crop. AAUC-2 recorded maximum vine length inside the rain shelter and open field. AAUC-2 recorded maximum number of branches also inside the rain shelter than open field. During rainy season Kuruppamthara Local had more vine length and number of branches inside the rain shelter and open field. Variety Poinsette produced male flower earlier than other varieties during summer season inside the rain shelter but in the open field Kuruppamthara Local was earlier than other varieties. During rainy season, Poinsette was earlier than other varieties under both growing condition. During both season, this variety produced female flower earlier than other varieties under two growing conditions. During summer season, AAUC-2 produced female flower at lowest node in the open field. Poinsette was early to harvest inside the rain shelter during summer and Kuruppamthara Local was early in the open field. But during rainy season, AAUC-2 was early inside the rain shelter and Poinsette in the open field. AAUC-2 recorded highest crop duration under two growing condition during summer season and Kuruppamthara Local had maximum duration during rainy season. AAUC-2 recorded maximum number of harvests under two growing conditions during summer season and inside the rain shelter during rainy season. Kuruppamthara Local recorded maximum number of harvests in the open field during rainy season. Same pattern was observed in the case of fruits per plot and yield per plot. During summer season maximum fruit weight was recorded by variety Kuruppamthara Local under two growing condition and rainy also this variety recorded maximum fruit weight in the open field. But inside the rain shelter AAUC-2 recorded maximum fruit weight. AAUC-2 recorded maximum fruit length under two growing conditions during two seasons. Kuruppamthara Local recorded maximum fruit girth and flesh thickness under two growing conditions during two seasons. AAUC-2 produced maximum number of seeds in the open field during rainy season than summer season. During rainy season, inside the rain shelter horizontally trailed varieties had highest yield than vertically trailed varieties and there was no significant difference in the open field. During summer season trailing methods had no significant influence on yield per plant. Pest attack was minimum during both seasons under two growing conditions and the main diseases were damping off and mosaic. Severity of mosaic diseases was high during rainy season. Cracking was observed during summer season and variety Poinsette inside the rain shelter recorded highest percentage of cracking. During summer season, cost benefit ratio inside the rain shelter was 1:5.15 and in the open field cost benefit ratio was calculated as 1:4.8. During rainy season, cost benefit ratio of rain shelter crop was 1:1.4. In the open field, the cost benefit ratio during rainy season was 1:6.0. From this study it can be concluded that AAUC-2 is the ideal variety for off season (summer) cultivation inside rain shelter. Kuruppamthara Local is ideal for open field cultivation during rainy season under vertical trailing system.
Response of chilli genotypes to ethephon whole plant sprays
(Kerala Agricultural University, 1985) Indira, P; Gopalakrishnan, P K; Peter, K V
Response of chilli genotypes to 4 levels of ethephon (0,100, 200 and 300 ppm) was studied during May-December 1981 and October-March 1981-82 seasons. The 4 levels of ethephon made significant differences for days to first fruitset and days to first red chilli harvest. Yield increased with ethephon application though it was not statistically significant. Plant stature was affected resulting in dwarf plant habit. Differential response to ethephon application was recorded only for days to first fruitset. Ethephon has only a limited use in chilli.
