A present experiment was conducted during the kharif season 2019 at the Research Farm, JNKVV, Jabalpur (M.P.) to study the efficacy of herbicidal mixtures against weed flora in direct-seeded rice under rainfed and irrigated agroecosystems. The experiment was laid out in a split-plot design with rainfed and irrigated agroecosystems in main plot treatments and eight weed control herbicides in sub-plot treatments. Among all kinds of dicot as well as monocot weeds Echinochloa colona and Alternanthera sessilis were the most dominant with a mean relative density of (30 and 28.6%) and (26 and 25%) respectively, under rainfed and irrigated agroecosystems. The maximum weed control efficiency under both rainfed and irrigated rice was observed in plots receiving hand weeding which was closely followed by bispyribac sodium at 25 g a.i./ha. Growth parameters, yield attributes as well as grain yield of direct-seeded rice were higher in plots receiving bispyribac sodium 10% SC at 25 g a.i./ha at 20 DAS except for hand weeding twice which registered the maximum values of these parameters.
Climate change is a natural process, but its pace has been accelerated by human interventions that draw attention of academicians, researchers and policymakers. Since last few decades it remained central theme of global discussion but general perception particularly among farming community is far from satisfactory. Agriculture is intricately interlinked with climate; hence any adverse change in climate will adversely affect agriculture. In this back ground, present study undertaken. The findings of the study revealed significant increase in maximum temperature and decrease in minimum temperature. At the same time annual precipitation found declining. Overall 72.5 per cent farming community found perceived the change across season. In nut shell, this is the first report on emerging contours of changing climate in the hilly region supplemented with community perception that may be foundation stone for future climate smart initiatives in the region.
In order to solve the problems of low utilization rate of straw round baler microbial inoculum and uneven spraying of microbial inoculum, a straw round baler microbial inoculum spraying control system based on feed quantity feedback was designed. According to the working principle and control characteristics of the self-propelled round baler, the design of the microbial inoculum spraying device, the design and selection of key components, the software design and the construction of the control system were carried out. In order to obtain the relevant parameters of the control system and test the effectiveness and stability of the control system, bench test and field tests were conducted. The relationship between PWM duty cycle and dynamic flow rate of nozzle spraying was obtained in the bench test, which provides the basis for intelligent control of microbial inoculum spraying. The field test showed that the total microbial inoculum spraying volume and auxiliary circuit microbial inoculum spraying volume were changed accordingly with the change of feed quantity. This control system can meet the design requirements, and can be adjusted according to the change of feed quantity, which can effectively improve the utilization rate of microbial inoculum.
The present investigation was undertaken to obtain information on theextent of heterosis and to identify potential parental lines and cross combinations for genetic improvement in brinjal usingdiallel excluding reciprocal. The crosses PB-6 x PB-101 and BARI x PusaUpkar showed highest economic heterosis for yield attributing traits, can be utilized for commercial exploitation of heterosis for obtaining maximum yield. It can also be concluded that for total yield per plant (Kg) SMB-115, Pant Rituraj (PR) and PB-101 were established as good general combiners and yield per hectare (q). Hence, the parents can be utilized for further investigation and genotypes improvement in respective traits of brinjal. The crosses PB-6 x PB-101, BARI x Pant Samrat and BARI x PusaUpkar highest sca effect for most the characters. However, these cross combinations can be utilized as commercially exploited to higher yield. Wild relatives of eggplant are commonly exploited for eggplant improvement, but the genetic improvement relies on the information of the genetic basis of inheritance of traits.
Thirty basmati and non basmati rice genotypes were evaluated for GxE interaction and stability performance under transplanted rice production systems at RRS, Kaul, CCS HAU, Hisar, (Haryana) during Kharif season. The experiment carried out 30 genotype using Randomized Complete Block Design with three replications. Micro-environments were created by using different dates of sowing. GxE interaction and stability of genotypes for days to 50% flowering, days to maturity, plant height, panicle length, number of tillers per plant, harvest index, number of grains per panicle, biological yield per plant and grain yield per plant were analyzed by Eberhart and Russell’s method. The genotypes, environments and genotype × environment interaction components showed significant differences for most of the traits when tested against pooled deviation revealed that the selected genotypes are rich in variation and environments were different from each other and wide differential response of genotypes in changing environments. The genotype main effects, environment (linear) and the E+GxE (linear) interaction were all highly significant. Pusa basmati 1 obtained as a stable genotype for number of grains per panicle and genotypes such as HKR 12-2, HKR 11-87, HKR 07-147, HKR 11-79, IR 91648-B-59-B-1-1, IR 91648-B-2-38-B-1-2, HKR 47and HKR 48, were found suitable for grain yield for favourable environments.
