This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Stigma is receptive from a day earlier to anthesis and continued for 2 days after anthesis. Chilli plant is often cross pollinated crop with 50% of natural crossing. Application of growth regulator to chilli plant either before bloom or at flowering suppress stamen formation leading to male sterility. Providing support services and best management practices for augmenting the marketing development efforts of the groups agricultural input companies (NFCL and NACL). Sow chilli seeds as early as possible (January or February for the hot varieties). A kilogram seeds contain 120-170 thousand seeds. after anthesis. Leaf thickness has bearing on pest tolerance especially thrips. Over 90 percent of the capsaicin found in the pericarp is found in the dissepiment. High branching is preferred in chilli for easy picking of fruits and for effective inter cultivation and to prevent rotting of fruits. The tip of epicotyle is called plumule. Recently example in fertilizers includes the development of Customized Fertilizer Grades (for NFCL across India that are crop and location specific have not only reduced the current consumption of fertilizers of farmers but have significantly enhanced crop yields and farmer incomes) that are expected to add significant revenues to the company. Seeds start developing 15 days after Answer Now and help others. Red ripe fruits are valued for colour and flavour. Increase or decrease seed content in fruits. The other major carotenoids which contribute to red colour are capsolubin (6.4%) and zeaxanthin (2.3%).

Annuals – plants which complete their life-cycle in one season eg: mustard, sunflower; Biennials- plants which complete their life-cycle in two seasons eg: radish, beetroot; Perennials – plants which live for a number of years and produce flowers and fruits at specific seasons every year eg: mango, termarind. Morphology of a Gram Seed (Cicer arietinum): Gram seed (Fig. 11th grade. The place of origin of the vascular strand from the embryo axis is called cotyledonary node. The solubilised food is absorbed by it and then transferred to the embryo axis. However, there is a lack of adequate Management knowledge and skills amongst the professionals. Moreover, chilli crop picks up its growth after receipt of rains. The pollen grains are fertile a day before anthesis with maximum fertility on the day of anthesis. Question 2. During germination, the radicle comes out first through the micropyle and grows to form a tap root.
