Assessment of Chilli hybrids for Growth, yield and Economics at Tiruvallur District of Tamilnadu
Hot pepper or Chilli (Capsicum annuum L.) is an important and widely cultivated vegetable and spice crops of India (Arun Kumar, 2006). Assessment of chilli hybrids for growth, yield, economics and higher productivity was conducted in five different farmer’s field during the year 2017-2018 at Ellapuram and Ekkadu blocks under on farm trial to know about the performance of chilli hybrids Viz., TNAU CO (ch)1 and IIHR Arka Harita. Several growth, yield and economical characters of the two hybrids were studied in comparison with the local variety Arani local chilli. The results showed that Arka Harita exhibited the highest values for growth, yield and economic traits. The growth characters like plant height (49.5), number of fruits per plant (81.20), fruit length (10.4 cm), market preference (very good) were observed the highest values in Arka Harita followed by TNAU CO (ch)1 (48.42 cm, 77.8, 10.7 cm and good) whereas local variety recorded the lowest values (44.26 cm, 65.4, 10.0 cm and average). Arka Harita recorded the minimum number of days for 50 per cent flowering (42) and number of days to 1st harvesting of fruits (80.48). Arka Harita recorded the highest number of fruits per plant (81.2) followed by TNAU CO (ch)1 is (77.8) whereas the local variety registered the lowest number of fruits per plant of 65.40. Regarding yield characters, Arka Harita recorded the highest fresh pod yield (29.04 t/ha) and dry pod yield (6.0 t/ha) followed by TNAU CO (ch) 1 (fresh pod 26.6 t/ha and dry pod 5.3 t/ha) whereas local variety recorded the lowest yield of 18.8 t/ha as fresh pod yield and 1.8 t/ha as dry pod yield. With respect to benefit cost ratio, Arka Harita recorded the highest ratio of fresh pod (3.05) and dry pod (5.58) with the net profit of fresh pod (Rs.2,34,487) and dry pod (Rs. 5,21,897) followed by TNAU CO (ch)1 of fresh pod (2.76) and dry pod (5.08) with the net profit of fresh pod (Rs.1,95,781) and dry pod (Rs.4,40,486) respectively, whereas local variety observed the lowest BC ratio (fresh pod 1.82; dry pod 1.52) and net profit for (fresh pod Rs.97,177; dry pod Rs.59,559). Thrips incidence was low in Arka Harita (25.4 per cent) when compare to local variety (16.4 per cent). Arka Harita recorded higher technology gap (2.96 t/ha), extension gap (10.2 t/ha) and harvest index (10.1 per cent), compare to local variety and also showed high parentage yield increase over local type and recorded 54.10 per cent increase yield.
Evaluation of coconut equivalent yield and economics of coconut based high density multispecies cropping system in coastal Odisha.
An experiment on “Evaluation of coconut equivalent yield and economics of coconut based high density multispecies cropping system in coastal Odisha.” was conducted in the experimental farm, under the Department of Fruit Science & Horticulture Technology, College of Agriculture, OUAT, and Bhubaneswar during the period July 2016 to June 2018. The crop combination taken in the cropping system was coconut + banana+ pineapple + guava + taro. The treatments consists of T1: 75% of recommended NPK + 25 % N through organic recycling with vermicompost, T2: 75% of Recommended NPK+ 25% N through organic recycling with vermicompost + PGR*; T3: 50 % of recommended NPK + 50 % N through organic recycling with vermicompost + in situ green manuring+ vermicompost wash + biofertilizers; T4:50 % of recommended NPK + 50 % N through organic recycling with vermicompost + in situ green manuring + vermicompost wash + biofertilizer + plant growth regulator*; T5: Fully organic (100 % N through organic recycling with vermicompost + in situ green manuring + vermicompost wash + CCP+ biofertilizer ; T6: Fully organic (100 % organic recycling with vermicompost + in situ green manuring + vermicompost wash + CCP) + biofertilizer + PGR*; T7 : Sole cropping of coconut with 100% recommended doses of fertilizer. The experiment was designed in randomized block design (RBD), with 7 treatments replicated 3 times. During the experimental period the average CEY of various intercrops varied between 2349.89 nuts ha-1 annum-1 and 20267.14 nutsha-1 annum-1, lowest with colocasia and highest with pineapple. The gross return obtained from one hectare of land ranged from Rs. 258773/ha-1 to Rs 331874 in cropping system and it was only Rs. 58,116/ in mono-cropping of coconut. Among all the combinations, the maximum (pooled mean) B:C ratio was 1:3.16 which was recorded in the system where crops grown with 75% RDF + 25% N through vermicompost with plant growth regulators.
Characterization of onion (Allium cepa L.) genotypes for agro- morphological and yield traits in the Bundelkhand region
A field experiment was conducted to ascertain the production potential of different onion varieties and to identify the most suitable high yielding varieties with better growth, yield and quality. The experiment was carried out during the rabi season of 2019-20 at the experimental research farm of RLBCAU, Jhansi. Nineteen onion varieties were evaluated in Randomized block design with three replications. The data analysis revealed sufficient variability among all the genotypes for all the studied traits. The results depicted that, NHRDF Red-4 performed better with respect to majority of the yield and contributing traits and it can be further considered for multiple trials for further evaluation. The highest number of leaves, Polar diameter of bulb, leaf diameter was recorded in the variety Pusa Sona.
Effect of Chitosan and Mulching on Yield attributing characters and Yield Of Sweet pepper
Field experiments were carried out to study the effect of Chitosan and mulching on yield attributing characters and yield of sweet pepper (CV. Indra) in Rayagada district of Southern Odisha during September-January of 2019-20 and 2020-21. The experiments were laid out in Factorial Randomized Block Design with three replications and twelve treatments viz., T1: No mulch + No Chitosan, T2: No mulch + Chitosan@ 20PPM, T3: No mulch + Chitosan@40PPM, T4: No mulch + Chitosan@60PPM, T5: Silver Plastic mulch + No Chitosan, T6: Silver Plastic mulch+ Chitosan @20 PPM, T7: Silver Plastic Mulch +Chitosan @ 40 PPM, T8: Silver Plastic Mulch + Chitosan @ 60PPM, T9: Paddy Straw Mulch@ 7.5t/ha + No Chitosan, T10: Paddy Straw mulch @ 7.5t/ha + Chitosan @ 20PPM, T11: Paddy Straw Mulch@ 7.5t/ha + Chitosan @ 40PPM, T12: Paddy Straw Mulch @ 7.5t/ha + Chitosan @ 60PPM. The present study revealed that the maximum plant height (48.62 cm) was obtained with Paddy straw mulch + Chitosan 60PPM, where as maximum fruiting branches (8.20), maximum fruit weight (106.80g), polar diameter (7.75cm), shoulder diameter (6.51cm) and fruit yield (31.55t/ha) was recorded with Silver Plastic Mulch + Chitosan @ 40 PPM. The less the number of days required for flowering and fruiting the fruit can reach the market early and can fetch higher price which was directly related to higher return to the farmer and it was obtained by application of Chitosan @ 60 PPM with silver plastic mulching (21.9 days for flowering and 52.7 days for fruiting).
MULTI MILLETS BASED THERAPEUTIC FOOD MIXES FOR NUTRITIONAL SECURITY
Millets are a group of highly variable small seeded grasses, widely grown around the world as cereal crops/ grains for fodder and human food. In India, eight millets species (Sorghum, Pearl millet, Finger millet, Foxtail millet, Kodo millet, Proso millet, Barnyard millet and Little millet) are commonly cultivated under rain fed conditions. The diet based on millets and leafy vegetables having antidiabetic properties gives a new approach in the treatment of diabetic mellitus. The study was carried out to formulate multi millet based convenient chappathi and dosa mix with incorporation of dried drumstick and palak leaves and evaluated the anti diabetic effect of these mixes in alloxan induced diabetic albino rats. All the developed four mixes are scored higher acceptability and provided high amount of fibre, iron and beta carotene. In the anti diabetic study, rats were divided into 6 groups of 6 animals each. Group 1 served as non diabetic control, Group 2 as diabetic control and Groups 3,4, 5 and 6 served as treatment groups. Diabetic was induced in rats by administration of alloxan monohydrate (150mg/kg) through the intra peritoneal route. Treatment groups (G3-G6) received diet of (100mg/kg of body weight) multi millets drumstick leaves chappathi mix (T1); multi millet palak leaves chappathi mix (T2); multi millet drumstick dosa mix (T3) and multi millet palak leaves dosa mix (T4) respectively. After the 28 days of treatment, diabetic rats showed highly significant reduction in blood glucose levels when compared to diabetic control and non diabetic groups. Hence the study concluded that multi millets and leafy vegetable based instant mixes have an effective antidiabetic property which controlling the blood glucose levels in the rats and also this study will create a new avenue to formulate the special convenient food mixes for diabetic people.
