Phenology, thermal indices and yield prediction models of indigenous aromatic rice of West Bengal, India

Phenology, thermal indices and yield prediction models of indigenous aromatic rice of West Bengal, India

The phenological development and thermal unit requirements of seven aromatic rice landraces of West Bengal were studied in randomized block design (RBD) with 3 replications at ‘C’ Block Farm (22o 99’ N, 88o 45’ E, 9.75 m.s.l.), Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal, India during kharif (wet) season of 2008 and 2009. All seven indigenous scented rice cultivars were long-duration types (140.0 – 148.3 days) and differed slightly among themselves towards attainment of different phenophases and accumulation of heat units.

A study on phytochemicals and mineral content of indigenous red rice of Assam, India

A study on phytochemicals and mineral content of indigenous red rice of Assam, India

Considering nutraceutical potentiality of phytochemicals, a few indigenous red rice germplsams of Assam, India were analysed for various phytochemicals, antioxidant activities and a few mineral contents. Among the sixteen germplasm analysed in their brown form, the total phenol content, total flavonoid content, and the anthocyanin content per100 gm dry matter ranged from752.89 mg±18.12 (‘Ranga Dariya’) to 2223 mg±33.48 (‘Amana Bao’), 252.12±15.40mg (‘Ixojoy’) to 1000.75±86.93mg (‘Dal Bao’) and 76.05± 0.32 µg (‘Kolaguni’) to159.42±15.97 µg (‘Betu’), respectively. For the polished form of rice, the same in 100 gm dry matter ranged from76.51 mg±1.46 in ‘Ranga Dariya’ to 1409 mg±100.88 in ‘Kolaguni’, from 32.09± 7.17 mg in ‘Ranga Dariya’ to 374.46± 2.05mg in ‘Negheribao’ and from 17.91±5.08µg (‘Biroi’) to 115.42±11.72µg (‘Hurupibao’), respectively. The antioxidant activities were observed to be the highest 96.00±0.26% in ‘Negheribao’ (for brown form of rice) and 86.35± 3.88% in ‘Kenekuabao’ (for polished form of rice) and the lowest 81.54±0.23% in ‘Betu’(for brown form of rice) and 59.65±4.64 % in ‘Ranga Dariya’ (polished rice), respectively. In brown rice, on dry weight basis, the iron, zinc and manganese content ranged from 2.12-54.40 mg per 100 gm, 2.42 mg to 26.57mg per 100 gm and 0.04 mg per 100 gm to 25.13 mg per 100 gm, respectively.

Characterization and genetic potential of ginger genotypes evaluated in Terai Region of West Bengal, India

Characterization and genetic potential of ginger genotypes evaluated in Terai Region of West Bengal, India

Character association and path analysis studies were investigated in 2016-2017 and 2017- 2018 in all physical and rhizome characters of ginger to find out the influence of characters among themselves on yield. Characters were investigated according to the DUS descriptors as described by Indian Institute of Spices Research, Kozhikode, Kerala. Number of leaves had the highest positive direct effect (1.759) on yield followed by number of shoots (1.053) and rhizome thickness (0.460). The correlation coefficients among the different characters at phenotypic and genotypic levels revealed that Rhizome thickness (0.45*) was the only trait having positive and significant correlation with rhizome yield (t/ha). Number of leaves had the highest positive direct effect on yield followed by number of shoots and rhizome thickness indicating that selection should be made on the basis of these characters taking other characters into consideration, while making improvement in yield of ginger. In cluster analysis, gap statistics was done to find optimal number of clusters and two groups of clusters were found. So, genotypes GCP-39, SEHP-9, SE-8640, SG-2640, SE-8681 and ACC-247 should be chosen for cultivation among these genotypes in this region of West Bengal.

Factors responsible for adoption of Gobindabhog rice in some selected areas of Burdwan district, West Bengal, India

Factors responsible for adoption of Gobindabhog rice in some selected areas of Burdwan district, West Bengal, India

Adoption is a process of making a decision about an innovation of technology option offered to anyone. Even though we have brought about green revolution and moving for second green revolution, more than 60% of technology cannot reach the domain of farmer‟s innovation decision. So the present study takes care of adoption process of „Gobindabhog‟ famous traditional aromatic rice, to explore the process and complexity of its adoption and subsequent socialization. Aromatic rice like Gobindabhog has got social, ecological and economic importance. The general objective is estimating the factors responsible for adoption of Gobindabhog rice and following are the specific objectives: -1. To find out the relationship of the selected independent variables with the adoption behaviour of the farmers engaged in „Gobindabhog‟ rice cultivation. 2. To identify the degree to which the adoption behaviour may be predicted from this characteristics. 3. To access the different problems faced by the farmers hindering the adoption process and the measures suggested by them as remedies. The important relevation of the study depicts that the following independent variables i.e. Age (X1), Caste (X2), Family type (X3), Family size (X4), Education (X5) Area under „Gobindabhog‟ rice cultivation(X6), Land (X7), House (X8), Farm power (X9), Material possession (X10), Annual Income (X11), Social Participation (X12), Attitude towards „Gobindabhog‟ rice cultivation (X13), Knowledge about „Gobindabhog‟ Rice cultivation(X14), Market Orientation (X15), Production Orientation (X16), Risk Orientation (X17), Economic Motivation (X18), Innovation Proneness (X19), Massmedia exposure (X20), Personal Cosmopolite (X21), Personal Localite (X22) have got distinct contribution to the dependent variable i.e. Adoption of Gobindabhog rice cultivation. Analyzing the data using the statistical tools correlation of coefficient and multiple regression documented results were obtained.

Genetics of quality and yield traits using aromatic and non aromatic genotypes through generation mean analysis in rice (Oryza sativa L.)

Generation mean analysis was carried out with 5 generations (P1, P2, F1, F2, and F3) crossing 5 aromatic and 3 non-aromatic genotypes of rice for prime kernel quality characteristics and grain yield per plant. Besides main genetic effects (d and h), interaction effects (i and l) were also highly significant for quality traits, indicating the importance of epistasis exploitation in breeding for quality rices.

Growth and instability of pulses production in Andhra pradesh

Growth and instability of pulses production in Andhra pradesh

This paper analyses the growth rates and instability indices of major pulses in Andhra Pradesh. Decomposition analysis was carried out to measure the relative contribution of area and yield to the growth in total production of major pulses. The study period has been divided into two sub periods for the purpose of analysis of growth rates and decomposition analysis viz., 1995-96 to 2005-2006 and 2005-06 to 2015-16. Growth rate analysis showed that both the production and yield of major pulse crops were positive whereas the area was positive except for green gram and black gram. The instability indices indicate that during the periods I and II, instability in area, production and yield was high in red gram expect for yield in period I which was highest in bengal gram.
